Forward-Looking Statements

This Annual Report contains “forward-looking statements” as defined in the U.S. Private Securities Litigation Reform Act of 1995 and are intended to be covered by the safe harbor provided for under these sections. Our forward-looking statements are based on management’s assumptions and beliefs in light of the information currently available to it and may include, without limitation:

● Our and Cerro Verde’s costs and expenses;

● estimates of future costs applicable to sales;

● estimates of future exploration and production results;

● plans for capital expenditures;

● expected commencement dates of mining or metal production operations; and

● estimates regarding potential cost savings and operating performance.

The words “anticipate,” “may,” “can,” “plan,” “believe,” “estimate,” “expect,” “project,” “intend,” “likely,” “will,” “should,” “to be” and any similar expressions are intended to identify those assertions as forward-looking statements. In making any forward-looking statements, we believe that the expectations are based on reasonable assumptions. We caution readers that those statements are not guarantees of future performance and our actual results may differ materially from those anticipated, projected or assumed in the forward-looking statements. Important factors that can cause our actual results to differ materially from those anticipated in the forward-looking statements include:

● The results of explorations at our mines and those of our mines of joint venture partners;

● the results of our joint ventures and our share of the production of, and the income received from, such joint ventures;

2

● commodity prices;

● production rates;

● geological and metallurgical assumptions;

● industry risks;

● timing of receipt of necessary governmental permits or approvals;

● regulatory changes;

● political risks;

● inaccurate estimates of reserves or mineralized material not in reserve;

● anti-mining protests or other potential issues with local community relationships;

● labor relations;

● pandemics, or the future outbreak of any other highly infectious or contagious disease, including the COVID-19 pandemic;

● the effects of a pandemic or epidemic and any subsequent mandatory regulatory restrictions

● containment measures environmental risks;

● our ability to finance capital expenditures;

● our ability to replace reserves as they become depleted;

● our ability to maintain positive relationships with the communities in which we operate;

● information technology failures;

● risks relating to tailings dams;

● legal proceedings and their effect on our existing financing agreements;

● any future defaults in respect of our outstanding debt agreements;

● the ongoing conflict between Russia and Ukraine; and

● other factors described in more detail under “Item 3. Key Information—D. Risk Factors.”

Many of the assumptions on which our forward-looking statements are based are likely to change after our forward-looking statements are made, including, for example, commodity prices, which we cannot control, and Cerro Verde’s production volumes and costs, some aspects of which we may or may not be able to control. Further, we may make changes to our business plans that could or will affect our results. We do not intend to update our forward-looking statements, notwithstanding any changes in our assumptions, changes in our business plans, our actual experience or other changes, and we undertake no obligation to update any forward-looking statements more frequently than required by applicable securities laws.

● Concentrate: A metal-rich product resulting from a mineral enrichment process such as gravity concentration or flotation, in which most of the desired mineral has been separated from the waste material in the ore.

● Crushing: Initial process of reducing ore particle size by impact to render it more amenable for further processing.

● Cut-off Grade (CoG): The grade of mineralized rock above which it becomes profitable to extract the mineralization.

● Deposit: A mineralized body thathas been physically delineated by sufficient drilling, trenching, and/or underground work, and found to contain a sufficient average grade of metal or metals to warrant further exploration and/or development expenditures. Such a deposit does not qualify as a commercially mineable ore body or as containing reserves or ore, unless final legal, technical and economic factors are resolved.

● Development: The process of constructing a mining facility and the infrastructure to support the facility is known as mine development.

● Diamond drill: A type of rotary drill in which the cutting is done by abrasion rather than percussion.

Factors Relating to the Company

We have incurred losses in the past and may incur losses in the future.

For the years ended December 31, 2021, 2020 and 2019, our net loss was $(262.8) million $(150.3) million and $(28.5) million, respectively. We may incur losses in the future and there can be no assurance that we will be able to operate profitably during future periods. If we are unable to operate profitably during future periods, and are not successful in obtaining additional financing, we could be forced to cease certain exploration and evaluation programs and mine development activities as a result of insufficient cash resources.

Our financial performance is highly dependent on the performance of our partners under our mining exploration and operating agreements.

Our participation in joint venture mining exploration projects and mining operations with other experienced mining companies is an integral part of our business strategy. Our partners, co-venturers and other shareholders in these projects generally contribute capital to cover the expenses of the joint venture or provide critical technological, management and organizational expertise. The results of these projects can be highly dependent upon the efforts of our joint venture partners and we rely on them to fulfill their obligations under our agreements.

Our financial performance is highly dependent on the prices of gold, silver, copper and other metals.

The results of our operations are significantly affected by the market price of specific metals, which are cyclical and subject to substantial price fluctuations. Our revenues are derived primarily from the sale of gold and silver and the revenues of Cerro Verde, in which we have a material equity investment, are derived primarily from copper sales. The prices that we and Cerro Verde obtain for gold, silver, copper and ore concentrates containing such metals, as applicable, are directly related to world market prices for such metals. Such prices have historically fluctuated widely and are affected by numerous factors beyond our control, including (i) the overall demand for and worldwide supply of gold, silver, copper and other metals; (ii) levels of supply and demand for a broad range of industrial products; (iii) the availability and price of competing commodities; (iv) international economic and political trends; (v) currency exchange fluctuations (specifically, the U.S. Dollar relative to other currencies); (vi) expectations with respect to the rate of inflation; (vii) interest rates; (viii) actions of commodity markets participants; and (ix) global or regional political or economic crises.

We have in the past engaged in hedging activities, such as forward sales and option contracts, to minimize our exposure to fluctuations in the prices of gold, silver and other metals; however, we and our wholly owned subsidiaries no longer hedge the price at which our gold and silver will be sold. In addition, Cerro Verde does not engage in hedging activities. As a result, the prices at which we and Cerro Verde sell gold, silver, copper and ore concentrates, as applicable, are fully exposed to the effects of changes in prevailing market prices. See “Item 11. Quantitative and Qualitative Disclosures About Market Risk” and Note 33 to the Consolidated Financial Statements. For information on gold and silver prices for each of the years in the five-year period ended December 31, 2019, see “Item 4. Information on the Company—Buenaventura—B. Business Overview—Sales of Metal Concentrates.”

On December 31, 2021 and March 31, 2022, the morning fixing price for gold on the London Bullion Market was US$ 1,820.10 per ounce and US$1,924.10 per ounce, respectively. On December 31, 2021 and March 31, 2022, the afternoon fixing spot price of silver on the London market, or “London Spot,” was US$23.085 per ounce and US$24.815 per ounce, respectively. On December 31, 2021 and March 31, 2022, the London Metal Exchange Settlement Price for copper was US$9,692 per ton and US$10,337 per ton, respectively.

12

The world market prices of gold, silver and copper have historically fluctuated widely. We cannot predict whether metal prices will rise or fall in the future. A continued decline in the market price of one or more of these metals could adversely impact our revenues, net income and cash flows and adversely affect our ability to meet our financial obligations. If prices of gold, silver and/or copper should decline below our cash costs of production and remain at such levels for any sustained period, we could determine that it is not economically feasible to continue production at any or all of our mines. We may also curtail or suspend some or all of our exploration activities, which may result in our depleted reserves not being replenished. This could further reduce revenues by reducing or eliminating the profit that we currently expect from reserves. Such declines in price and/or reductions in operations could cause significant volatility in our financial performance and adversely affect the trading prices of our Common Shares and ADSs.

The COVID-19 pandemic has has had, and may continue to have, an adverse impact on our business, financial condition, and results of our operations, the global economy, and the demand for and prices of oil and natural gas. The unprecedented nature of the current situation makes it impossible for us to identify all potential risks related to the pandemic or estimate the ultimate adverse impact that the pandemic may have on our business.

The COVID-19 pandemic, and the actions taken by third parties, including, but not limited to, governmental authorities, businesses and consumers, in response to the pandemic, have adversely impacted the global economy and created significant volatility in the global financial markets. Business closures, restrictions on travel, “stay-at-home” or “shelter-in-place” orders, and other restrictions on movement within and among communities have significantly reduced demand for and the prices of oil and natural gas. As of the date of this annual report, efforts to contain COVID-19 have not been successful in many regions, vaccination programs have encountered delays, and the global pandemic remains ongoing. A continued prolonged period of such reduced demand, the failure to timely distribute or the ineffectiveness of any vaccines, the failure to develop adequate treatments, and other adverse impacts from the pandemic may materially adversely affect our business, financial condition, cash flows, and results of operations.

Our operations rely on our workforce being able to access our mines, structures and facilities located upon or used in connection with our mining activities. Additionally, because we have implemented remote working procedures for a significant portion of our workforce for health and safety reasons and/or to comply with applicable national, state, and/or local government requirements, we rely on such persons having sufficient access to our information technology systems, including through telecommunication hardware, software and networks. If a significant portion of our workforce cannot effectively perform their responsibilities, whether resulting from a lack of physical or virtual access, quarantines, illnesses, governmental actions or restrictions, information technology or telecommunication failures, or other restrictions or adverse impacts resulting from the pandemic, our business, financial condition, cash flows, and results of operations may be materially adversely affected.

The unprecedented nature of the current situation resulting from the COVID-19 pandemic makes it impossible for us to identify all potential risks related to the pandemic or estimate the ultimate adverse impact that the pandemic may have on our business, financial condition, cash flows or results of operations. Such results will depend on future events, which we cannot predict, including the scope, duration and potential reoccurrence of the COVID-19 pandemic or any other localized epidemic or global pandemic, the distribution and effectiveness of vaccines and treatments and the actions taken by third parties, including, but not limited to, governmental authorities, customers, contractors and suppliers, in response to the COVID-19 pandemic or any other epidemics or pandemics. The COVID-19 pandemic and its unprecedented consequences have amplified, and may continue to amplify, the other risks identified in this annual report.

Economic, mining and other regulatory policies of the Peruvian government, as well as political, regulatory and economic developments in Peru, may have an adverse impact on our and Cerro Verde’s businesses.

Our and Cerro Verde’s activities in Peru require us to obtain mining concessions or provisional permits for exploration and processing concessions for the treatment of mining ores from the Peruvian Ministry of Energy and Mines (the “MEM”). Under Peru’s current legal and regulatory regime, these mining and processing rights are maintained by meeting a minimum annual level of production or investment and by the annual payment of a concession fee. A fine is payable for the years in which minimum production or investment requirements are not met. Although we are, and Cerro Verde has informed us that they are, current in the payment of all amounts due in respect of mining and processing concessions, failure to pay such concession fees, processing fees or related fines for two consecutive years could result in the loss of one or more mining rights and processing concessions, as the case may be.

13

Mining companies are also required to pay the Peruvian government mining royalties and/or mining taxes. See “Item 4. Information on the Company—Buenaventura—B. Business Overview—Regulatory Framework—Mining Royalties and Taxes.” We cannot assure you that the Peruvian government will not impose additional mining royalties or taxes in the future or that such mining royalties or taxes will not have an adverse effect on our or Cerro Verde’s results of operations or financial condition. In addition, future regulatory changes, changes in the interpretation of existing regulations or stricter enforcement of such regulations, including changes to our concession agreements, may increase our compliance costs and could potentially require us to alter our operations. We cannot assure you that future regulatory changes will not adversely affect our business, financial condition or results of operations.

In the political environment, the current government has faced significant opposition, and, as a result, two motions to impeach the president have been made. On December 7, 2021 the Congress voted on the first motion which resulted in a decision  not to impeach the president with a majority of 76 votes against the motion. Later, on March 28, 2022, the Congress voted again on impeachment, which was rejected with 54 votes against the motion.

Environmental and other laws and regulations may increase our costs of doing business, restrict our operations or result in operational delays.

Our and Cerro Verde’s exploration, mining and milling activities, as well our smelting and refining activities, are subject to a number of Peruvian laws and regulations, including environmental laws and regulations.

Additional matters subject to regulation include, but are not limited to, concession fees, transportation, production, water use and discharges, power use and generation, use and storage of explosives, surface rights, housing and other facilities for workers, reclamation, taxation, labor standards, mine safety and occupational health.

We anticipate additional laws and regulations will be enacted over time with respect to environmental matters. The development of more stringent environmental protection programs in Peru could impose constraints and additional costs on our and Cerro Verde’s operations and require us and Cerro Verde to make significant capital expenditures in the future. Although we believe that we are substantially in compliance and Cerro Verde has advised us that they are substantially in compliance, with all applicable environmental regulations, we cannot assure you that future legislative or regulatory developments will not have an adverse effect on our or Cerro Verde’s business or results of operations. See “Item 4. Information on the Company—Buenaventura—B. Business Overview—Regulatory Framework—Environmental Matters” and “—Permits” and “Item 4. Information on the Company—Yanacocha—B. Business Overview—Environmental Matters.”

Our ability to successfully obtain key permits and approvals to explore for, develop and successfully operate mines will likely depend on our ability to do so in a manner that is consistent with the creation of social and economic benefits in the surrounding communities. Our ability to obtain permits and approvals and to successfully operate in particular communities or to obtain financing may be adversely impacted by real or perceived detrimental events associated with our activities or those of other mining companies affecting the environment, human health and safety or the surrounding communities. Delays in obtaining or failure to obtain government permits and approvals may adversely affect our operations, including our ability to explore or develop properties, commence production or continue operations.

Our operations are subject to physical challenges related to climate change

Climate change may have an adverse impact on the regions where our operations are located. Some of the risks include droughts, heavy precipitation or extremely high temperatures. Extreme weather conditions, such as floodings, may damage the roads and potentially reduce our productivity and increasing our costs. Roads blocked as a consequence of floods could also increase the lead times for mineral concentrates and supplies.

14

Our business and operations could be negatively affected as a result of Russia’s invasion of Ukraine, the sanctions imposed against Russia as a result and the effects of the conflict on the global economy

We do not depend on suppliers in the involved countries. However, our business and operations may be adversely affected by the political tensions, hostility and instability caused by the conflict currently ongoing in Europe. For example, the invasion of Ukraine by Russia in February 2022 led to the imposition of a series of economic sanctions by, among others, the United States, the European Union, the United Kingdom, Japan and Switzerland on Russia, certain Russian financial institutions and several politically linked individuals.

The conflict is having broader ramifications for the global economy as a result of increasing oil and natural gas prices, inflation and trade sanctions, which in turn could have an adverse effect on our business. If the conflict were to broaden to include other countries or regions, additional sanctions were put in place or the economy was further impacted by the conflict, it could exacerbate these risks and could have a material adverse effect on our business and operations.

Our estimates of mineral reserves and resources may be materially different from the total mineral quantities we actually recover, and changes in metal prices, operating and capital costs, and other assumptions used to calculate these estimates may render certain mineral reserves and resources uneconomical to mine.

There is a degree of uncertainty attributable to the estimation of mineral reserves and resources. Until mineral reserves and resources are actually mined and processed, the quantity of metal and grades must be considered as estimates only, and no assurance can be given that the indicated levels of metals will be produced. In making determinations about whether to advance any of our projects to development, we must rely upon estimated calculations for the mineral reserves and mineral resources and grades of mineralization on our properties. The estimation of mineral reserves and resources is a subjective process that is partially dependent upon the judgment of the qualified persons preparing such estimates. The process relies on the quantity and quality of available data and is based on knowledge, mining experience, statistical analysis of drilling results and industry practices. Valid estimates made at a given time may significantly change when new information becomes available.

Our estimates of mineral reserves and resources are based on geological interpretation and statistical inferences or assumptions drawn from drilling and sampling analysis made as of the date of such estimates. We periodically update our mineral reserves and resources estimates based on the conclusions of the relevant qualified persons with respect to new data from exploratory and infill drilling, results from technical studies and the experience acquired during the operation of the mine and metallurgical processing, as well as changes to the assumptions used to calculate these estimates.

Several of the assumptions used to calculate these estimates, including the market prices of commodities, operating and capital costs and mining and metallurgical recovery rates, among others, can greatly fluctuate, which may result in significant changes to our current estimates. These changes may also render it uneconomic to exploit some or all of our proven and probable mineral reserves and measured and indicated mineral resources and may ultimately result in a reduction of mineral reserves and resources.

In addition, inferred mineral resources have a great amount of uncertainty as to their existence and their economic and legal feasibility. You should not assume that any part of an inferred mineral resource will be upgraded to a higher category or that any of the mineral resources not already classified as mineral reserves will be reclassified as mineral reserves.

We depend on our ability to replenish our mineral reserves for our long-term viability.

Mineral reserves data is only indicative of future results of operations at the time the estimates are prepared and are depleted over time as we conduct our mining operations. We use several strategies to replenish and increase our mineral reserves that are depleted, including exploration activities and the acquisition of mining concessions. If we are unable to replenish our mineral reserves or develop our mineral resources, our business, results of operations and prospects would be materially adversely affected.

15

Our metals exploration efforts are highly speculative in nature and may not be successful.

Precious metals exploration, particularly gold exploration, is highly speculative in nature, involves many risks and is frequently unsuccessful. We cannot assure you that our or Cerro Verde’s metals exploration efforts will be successful. Once mineralization is discovered, it may take a number of years from the initial phases of drilling before production is possible, during which time the economic feasibility of production may change. Substantial expenditures are required to establish proven and probable ore reserves through drilling, to determine metallurgical processes to extract the metals from the ore and, in the case of new properties, to construct mining and processing facilities. As a result of these uncertainties, we cannot assure you that our exploration programs will result in the expansion or replacement of current production with new proven and probable ore reserves.

We base our estimates of proven and probable ore reserves and estimates of future cash operating costs largely on the interpretation of geologic data obtained from drill holes and other sampling techniques and feasibility studies. Advanced exploration projects have no operating history upon which to base estimates of proven and probable ore reserves and estimates of future cash operating costs. Such estimates are, to a large extent, based upon the interpretation of geologic data obtained from drill holes and other sampling techniques, feasibility studies which derive estimates of cash operating costs based upon anticipated tonnage and grades of ore to be mined and processed, the configuration of the ore body, expected recovery rates of the mineral from the ore, comparable facility and equipment operating costs, anticipated climatic conditions and other factors. As a result, it is possible that actual cash operating costs and economic returns based upon proven and probable ore reserves may differ significantly from those originally estimated. Moreover, significant decreases in actual over expected prices may mean reserves, once found, will be uneconomical to produce. It is not unusual in new mining operations to experience unexpected problems during the start-up phase. See “Item 5. Operating and Financial Review and Prospects—Cerro Verde—A. Operating Results” for the price per ounce used by us and Cerro Verde, respectively, to calculate our respective proven and probable reserves.

Increased operating costs could affect our profitability.

Costs at any particular mining location frequently are subject to variation due to a number of factors, such as changing ore grade, changing metallurgy and revisions to mine plans in response to the physical shape and location of the ore body. In addition, costs are affected by the price of commodities, such as fuel and electricity, as well as by the price of labor. Commodity costs are at times subject to volatile price movements, including increases that could make production at certain operations less profitable. Reported costs may be affected by changes in accounting standards. A material increase in costs at any significant location could have a significant effect on our profitability.

Our business is capital-intensive and we may not be able to finance necessary capital expenditures required to execute our business plans.

Precious metals exploration requires substantial capital expenditures for the exploration, extraction, production and processing stages and for machinery, equipment and experienced personnel. Our estimates of the capital required for our projects may be preliminary or based on assumptions we have made about the mineral deposits, equipment, labor, permits and other factors required to complete our projects. If any of these estimates or assumptions change, the actual timing and amount of capital required may vary significantly from our current anticipated costs. In addition, we may require additional funds in the event of unforeseen delays, cost overruns, design changes or other unanticipated expenses. We may also incur debt in future periods or reduce our holdings of cash and cash equivalents in connection with funding future acquisitions, existing operations, capital expenditures or in pursuing other business opportunities. Our ability to meet our payment obligations will depend on our future financial performance, which will be affected by financial, business, economic and other factors, many of which we are unable to control. There can be no assurance that we will generate sufficient cash flow or that we will have access to sufficient external sources of funds in the form of outside investment or loans to continue exploration activities at the same or higher levels than in the past or that we will be able to obtain additional financing, if necessary, on a timely basis and on commercially acceptable terms.

16

We engage in mergers and acquisitions activity in the ordinary course of business and may make future acquisitions and dispositions that may not achieve expected benefits.

In the future, we may decide to expand or contract by acquiring other companies in Peru or abroad in order to diversify our existing portfolio of products and services and expand our geographic footprint, or alternatively by disposing of some of our assets. Any future acquisitions and dispositions will depend on our ability to identity suitable candidates or buyers, negotiate acceptable terms, and obtain financing in the case of acquisitions. If future acquisitions or dispositions are significant, they could change the scale of our business and expose us to new geographic, political, operating and financial risks. In addition, each transaction involves a number of risks, such as the diversion of our management’s attention from our existing business, possible adverse effects on our results of operations, our inability to achieve the intended objectives of the transaction and potential unknown liabilities associated with the acquired assets.

Estimates of proven and probable reserves are subject to uncertainties and the volume and grade of ore actually recovered may vary from our estimates.

The proven and probable ore reserve figures presented in this Annual Report are our and Cerro Verde’s estimates, and there can be no assurance that the estimated levels of recovery of gold, silver, copper and certain other metals will be realized. Such estimates depend on geological interpretation and statistical inferences or assumptions drawn from drilling and sampling analysis, which may prove to be materially inaccurate. Actual mineralization or formations may be different from those predicted. As a result, reserve estimates may require revision based on further exploration, development activity or actual production experience, which could materially and adversely affect such estimates. No assurance can be given that our or Cerro Verde’s mineral resources constitute or will be converted into reserves. Market price fluctuations of gold, silver and other metals, as well as increased production costs or reduced recovery rates, may render proven and probable ore reserves containing relatively lower grades of mineralization uneconomic to exploit and may ultimately result in a restatement of proven and probable ore reserves. Moreover, short-term operating factors relating to the reserves, such as the processing of different types of ore or ore grades, could adversely affect our profitability in any particular accounting period.

We may be unable to replace reserves as they become depleted by production.

As we produce gold, silver, zinc and other metals, we deplete our respective ore reserves for such metals. To maintain production levels, we must replace depleted reserves by exploiting known ore bodies and locating new deposits. Exploration for gold, silver and the other metals produced is highly speculative in nature. Our exploration projects involve significant risks and are often unsuccessful. Once a site is discovered with mineralization, we may require several years between initial drilling and mineral production, and the economic feasibility of production may change during such period. Substantial expenditures are required to establish proven and probable reserves and to construct mining and processing facilities. There can be no assurance that current or future exploration projects will be successful and there is a risk that our depletion of reserves will not be offset by new discoveries. See “Item 5. Operating and Financial Review and Prospects—Cerro Verde—A. Operating Results” for a summary of our and Cerro Verde’s estimated proven and probable reserves as of December 31, 2021. On February 8, 2022, Buenaventura entered into binding agreements with Newmont to sell its total interest in Yanacocha. See detail in Note 1(e) to the Consolidated Financial Statements.

Our operations are subject to risks, many of which are not insurable.

The business of mining, smelting and refining gold, silver, copper and other metals is generally subject to a number of risks and hazards, including industrial accidents, labor disputes, unavailability of materials and equipment, unusual or unexpected geological conditions, changes in the regulatory environment, environmental hazards and weather and other natural phenomena such as earthquakes, most of which are beyond our control. Such occurrences could result in damage to, or destruction of, mining properties or production facilities, personal injury or death, environmental damage, delays in mining, monetary losses and possible legal liability. We and Cerro Verde each maintain insurance against risks that are typical in the mining industry in Peru and in amounts that we and Cerro Verde believe to be adequate but which may not provide adequate coverage in certain circumstances. No assurance can be given that such insurance will continue to be available at economically feasible premiums or at all. Insurance against certain risks (including certain liabilities for environmental pollution or other hazards as a result of exploration and production) is not generally available to us or to other companies within the industry.

Legal proceedings could have a material adverse effect on our business.

We are involved in legal proceedings against the Peruvian National Customs and Tax Administration Superintendence (“SUNAT”) in connection with ongoing tax disputes relating to an audit in respect of the Company’s income tax payments for the years 2007 and 2008 (and the tax consequences in respect of the years 2009 and 2010), in which SUNAT refused to recognize the Company’s deductions in respect of contracts for physical deliveries and certain contractual payments made by the Company on the basis that such payments would, according to SUNAT, correspond to an early settlement of financial derivative contracts in situations where the Company did not establish the purpose or risks covered by such instruments.

On November 26, 2020, following the intervening tax court’s decision to dismiss the Company’s appeal against certain Administrative Resolutions issued by SUNAT in connection with the above-referenced matter, SUNAT began collection proceedings in an aggregate amount of 2,107.5 million soles (approximately US$585.4 million), comprised of the original claim of 373.3 million soles (approximately US$103.7 million) plus penalties and accrued interest according to SUNAT’s estimations. On December 30, 2020, we entered into a deferral and payment plan in respect of the amounts claimed by SUNAT; however, we cannot assure you that we will be able to obtain additional waivers in the event of future defaults” below. As a result of our entering into such arrangements, on April 13, 2021, Fitch Ratings Inc. (“Fitch”) downgraded our credit rating to “BB” from “BB+”.

On July 30, 2021, the Company paid the full amount of the tax debt related to the 2007, 2008, 2009 and 2010 tax processes that were subject to deferment and installment and that are recorded in the caption “Trade and other receivables, net”, For the fiscal years 2007 and 2008, the total amount paid was S/1,584,227,000 (equivalent to US$398,548,000), which included updating of the debt to reflect interest accrued as of July 30, 2021, such interest amounting to S/78,279,000 (equivalent to US$19,693,000). For the fiscal year 2009, total amount paid was S/193,398,000 (equivalent to US$48,654,000), which included updating the debt to reflect interest accrued as of July 30, 2021, such interest amount to S/8,477,000 (equivalent to US$2,133,000). For the fiscal year 2010, which was subject to deferral and installment, the total amount paid was S/356,691,000 (equivalent to US$89,733,000) which included the updating of the debt to reflect interest accrued as of July 30, 2021, such interest amounting to S/16,762,000 (equivalent to US$4,217,000).

As of December 31, 2021, as a result of the advance payment mentioned above, the deferral and installment resolutions of the SUNAT tax debt have been rendered null, and the letters of credit that were delivered as collateral for said debt have been returned to the issuing banks.

We will continue to pursue appeals on this matter in Peruvian courts. These legal proceedings may be costly and time consuming and there can be no guarantee in respect of the final outcome of these proceedings or that SUNAT will not bring future claims against us.

Increases in equipment costs, energy costs and other production costs, disruptions in energy supply and shortages in equipment and skilled labor may adversely affect our results of operations.

In recent years, there has been a significant increase in mining activity worldwide in response to increased demand and significant increases in the prices of natural resources. The opening of new mines and the expansion of existing ones have led to increased demand for, and increased costs and shortages of, equipment, supplies and experienced personnel. These cost increases have significantly increased overall operating and capital budgets of companies like ours, and continuing shortages could affect the timing and feasibility of expansion projects.

Energy represents a significant portion of our production costs. Our principal energy sources are electricity, purchased petroleum products and natural gas. An inability to procure sufficient energy at reasonable prices or disruptions in energy supply could adversely affect our profits, cash flow and growth opportunities. Our production costs are also affected by the prices of commodities we consume or use in our operations, such as sulfuric acid, grinding media, steel, reagents, liners, explosives and diluents. The prices of such commodities are influenced by supply and demand trends affecting the mining industry in general and other factors outside our control, and such prices are at times subject to volatile movements. Increases in the cost of these commodities or disruptions in energy supply could make our operations less profitable, even in an environment of relatively high copper, gold or silver prices. Increases in the costs of commodities that we consume or use may also significantly affect the capital costs of new projects.

18

We may be adversely affected by labor disputes.

Our ability to achieve our goals and objectives is dependent, in part, on maintaining good relations with our employees. A prolonged labor disruption at any of our material properties could have a material adverse impact on our results of operations. We, Compañía Minera Coimolache S.A., or “Coimolache,” and Cerro Verde have all experienced strikes or other labor-related work stoppages in the past.

As of December 31, 2021, unions represented approximately 21% of our and our subsidiaries’ employees, including Coimolache’s employees and contractors. Although we consider our relationship with our employees to be positive, there can be no assurance that we will not experience strikes or other labor-related work stoppages that could have a material adverse effect on our operations and/or operating results in the future.

Our and Cerro Verde’s operations are subject to political and social risks.

Our and Cerro Verde’s exploration and production activities are potentially subject to political and social risks. Over the past several years, we have been the target of local political protests. In recent years, certain areas in the south and northern highlands of Peru with significant mining developments have experienced strikes and protests related to the environmental impact of mining activities. Such strikes and protests have resulted in commercial disruptions and a climate of uncertainty with respect to future mining projects.

In 2020, the Peruvian Central Government continued to support responsible mining as a vehicle for the growth and future development of Peru. However, we are unable to predict whether the Peruvian Central Government will continue to take similar positions in the future.

We cannot assure you that our business and operations will not be subject to local and community opposition in the future or that the continuation or intensification of community protests will not adversely affect our exploration and production activities or our results of operations or financial condition.

In addition, during 2011, Peru enacted Law No. 29785, the Law of Prior Consultation for Indigenous and Native Communities (Ley del Derecho a la Consulta Previa a los Pueblos Indígenas y Originarios, Reconocido en el Convenio 169 de la Organización Internacional del Trabajo). Implementing regulations thereunder were approved by Supreme Decree No. 001-2012-MC, which became effective on April 2, 2012. This law establishes a prior consultation procedure that the Peruvian government must undertake in concert with any local indigenous communities whose collective rights may be directly affected by new legislative or administrative measures, including the granting of new mining concessions. The implementing regulations specify the form and circumstances of the required consultation and the manner in which agreements will be formalized, and cap the consultation process at 120 calendar days. Under the law, the Peruvian governmental body responsible for issuing or approving the administrative measure or decree in question, rather than the affected local indigenous community, retains the right to approve or reject the relevant legislative or administrative matter following such consultation. However, to the extent that any future projects operated by us or Cerro Verde require legislative or administrative measures that impact local indigenous communities, the required prior consultation procedure may result in delays, additional expenses or failure to obtain approval for such new project.

We could face geotechnical challenges, which could adversely impact our production and profitability.

No assurances can be given that unanticipated adverse geotechnical and hydrological conditions, such as landslides and pit wall failures, will not occur in the future or that such events will be detected in advance. Geotechnical instabilities can be difficult to predict and are often affected by risks and hazards outside of our control, such as severe weather and considerable rainfall, which may lead to periodic floods, mudslides, wall instability and seismic activity, which may result in slippage of material.

Geotechnical failures could result in limited or restricted access to mine sites, suspension of operations, government investigations, increased monitoring costs, remediation costs, loss of ore and other impacts, which could cause one or more of our projects to be less profitable than currently anticipated and could result in a material adverse effect on our results of operations and financial position.

19

We rely on contractors to conduct a significant portion of our operations and mine development projects.

A significant portion of our operations and mine development projects are currently conducted by contractors. As a result, our operations are subject to a number of risks, some of which are outside our control, including:

● failure of a contractor to perform under its agreement;

● interruption of operations or increased costs if a contractor ceases its business due to insolvency or other unforeseen events;

● failure of a contractor to comply with applicable legal and regulatory requirements, to the extent it is responsible for such compliance; and

● problems of a contractor with managing its workforce, labor unrest or other employment issues.

In addition, we may incur liability to third parties as a result of the actions of our contractors. The occurrence of one or more of these risks could adversely affect our results of operations and financial position.

We are exposed to behaviors incompatible with our and Cerro Verde’s ethics and compliance standards.

Given the large number of contracts with suppliers and other partners to which we and Cerro Verde are a party, the geographic distribution of our operations and the great variety of parties that we interact with in the course of our business, we are subject to the risk that our employees, contractors and other persons having relations with us may misappropriate our assets, manipulate our assets or information or engage in money laundering or the financing of terrorism, for such person’s personal or business advantage. Our systems for identifying and monitoring these risks may not be effective to fully mitigate them in all circumstances. Such acts may result in material financial losses or reputational harm to us.

We are not, and do not intend to become, regulated as an investment company under the U.S. Investment Company Act of 1940, as amended (the “Investment Company Act”), and if we were deemed an “investment company” under the Investment Company Act, applicable restrictions could make it impractical for us to operate as contemplated.

As of December 31, 2021, we owned a 43.65% partnership interest in Yanacocha and a 19.58% partnership interest in Cerro Verde. These interests may constitute “investment securities” for purposes of the Investment Company Act. On February 8, 2022, the Company sold the entirety of its stake in Yanacocha to Newmont. As such, Yanacocha has been classified on our financial statements as an asset held for sale as outlined in Note 1(e) to our Consolidated Financial Statements.

Under the Investment Company Act, an investment company is defined in relevant part to include (i) any company that is or holds itself out as being engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities and (ii) any company that owns or proposes to acquire investment securities having a value exceeding 40% of such company’s total assets (exclusive of certain items) on an unconsolidated basis. Issuers that are investment companies within the meaning of the Investment Company Act, and which do not qualify for an exemption from the provisions of such act, are required to register with the Securities and Exchange Commission (the “SEC”) and are subject to substantial regulations with respect to capital structure, operations, transactions with affiliates and other matters. If we were deemed to be an investment company and did not qualify for an exemption from the provisions of the Investment Company Act, we would be required to register with the SEC and would be subject to such regulations, which would be unduly burdensome and costly for us and could adversely impact us.

We received an order from the SEC on April 19, 1996 declaring us to be primarily engaged in a business other than that of an investment company and, therefore, not an investment company within the meaning of the Investment Company Act. We intend to conduct our operations and maintain our investments in a manner, and will take appropriate actions as necessary, to ensure we will not be deemed to be an investment company in the future. The SEC, however, upon its motion or upon application, may find that the circumstances that gave rise to the issuance of the order no longer exist, and as a result may revoke such order. There can be no assurance that such order will not be revoked.

20

Our inability to maintain positive relationships with the communities in which we operate may affect our reputation and financial condition.

Our relationship with the communities in which we operate are critical to ensuring the future success of our existing operations and the construction and development of our projects. Adverse publicity generated by non-governmental organizations or local communities related to extractive industries generally, or our operations specifically, could have an adverse effect on our reputations or financial condition and may impact our relationships with the communities in which we operate. In addition, following the enactment of Law No. 29785, the Law of Prior Consultation for Indigenous and Native Communities in 2011, the Peruvian government must undertake a prior consultation procedure in concert with local indigenous communities whose collective rights may be directly affected by new legislative or administrative measures, including the granting of new mining concessions. Implementing regulations under Law No. 29785 were approved by Supreme Decree No. 001-2012-MC, which became effective on April 2, 2012. The implementing regulations specify the form and circumstances of the required consultation and the manner in which agreements will be formalized, and cap the consultation process at 120 calendar days. Our national reputation for maintaining positive relationships with the communities in which we operate may affect the outcome of any such prior consultation process involving approvals that we seek for new projects. While we are committed to operating in a socially responsible manner, there is no guarantee that our efforts in this regard will mitigate this potential risk. We have implemented extensive community relations and security and safety initiatives to anticipate and manage social issues that may arise at our operations.

Deterioration in our financial position or a downgrade of our ratings by a credit rating agency could increase our borrowing costs, and our business relationships could be adversely affected.

Credit rating agencies could downgrade our ratings either due to factors specific to Buenaventura, a prolonged cyclical downturn in the precious metals mining industries, macroeconomic trends (such as global or regional recessions) or trends in credit and capital markets more generally. For instance, on April 3, 2020, Moody’s Investors Service downgraded our unsecured corporate rating from “Ba2” to “B1” due to the deterioration of the commodities markets and a downturn in the precious metals mining sector, as well as concerns about our liquidity. On April 13, 2021, Fitch downgraded our credit rating to “BB” from “BB+” as a result of our entering into a deferral and payment plan in respect of the amounts claimed by SUNAT.

A deterioration of our financial position or a further downgrade of any of our credit ratings for any reason could increase our borrowing costs and have an adverse effect on our business relationships with customers and suppliers. A subsequent downgrade could adversely affect our existing financings, limit access to the capital or credit markets, or otherwise adversely affect the availability of other new financing on favorable terms, if at all, result in more restrictive covenants in agreements governing the terms of any future indebtedness that we incur, increase our borrowing costs, or otherwise impair our business, financial condition and operating results.

Our tailings dams are subject to significant environmental, safety and engineering challenges and risks that could adversely affect our business.

The rupture of a tailings dam or similar structure may cause severe damages. Currently, the Company owns 18 tailings dams, consisting of seven active and 11 inactive (those in the process of being closed or remediated) tailing dams, and other geotechnical structures. All seven active and one of the inactive tailings dams were built using the “downstream” raising method or were raised with filtered/compacted tailings. The remaining inactive tailings dams were built using the “upstream” raising method, which could present stability risks, especially related to liquefaction.

Management of these facilities is regulated in the jurisdiction where we operate and our programs are designed to comply with applicable national laws, permits and approved environmental impact studies.

The failure of tailings dams could cause loss of life and severe personal, property and environmental damages, which could further have an adverse effect on our business, results of operations and reputation.

21

We could be subject to information technology system failures, network disruptions, and breaches in data security which could negatively affect our business, financial position, results of operations, and cash flows.

As dependence on digital technologies is expanding, cyber incidents, including deliberate attacks or unintentional events have been increasing worldwide. Computers and telecommunication systems are used to conduct our exploration, development and production activities and have become an integral part of our business. We use these systems to analyze and store financial and operating data, as well as to support our internal communications and interactions with business partners. Cyber-attacks could compromise our computer and telecommunications systems and result in additional costs as well as disruptions to our business operations or the loss of our data.

A cyber-attack involving our information systems and related infrastructure, or those of our business partners, could disrupt our business and negatively impact our operations in a variety of ways, such as, among others:

● an attack on the computers which control our mining operations could cause a temporary interruption of our production while contingency manual systems are brought online;

● a cyber-attack on our accounting or accounts payable systems could expose us to liability to employees and third parties if their sensitive personal information is obtained;

● possible loss of material information, which in turn could delay productive processes and selling efforts, causing economic losses; or

● a cyber-attack on a service provider could result in supply chain disruptions, which could delay or halt our major development projects.

The laws of Peru related to anti-bribery and anti-corruption are still developing and could be less stringent than those of other jurisdictions, and our risk management and internal controls may not be successful in preventing or detecting all violations of law or of company-wide policies.

Our business is subject to a significant number of laws, rules and regulations, including those relating to anti-bribery and anti-corruption. However, the Peruvian regulatory regime related to anti-bribery and anti-corruption legislation is still developing and could be less stringent than anti-bribery and anti-corruption legislation which has been implemented in other jurisdictions.

In addition, our existing compliance processes and internal control systems may not be sufficient to prevent or detect all inappropriate practices, fraud or violations of law by our employees, contractors, agents, officers or any other persons who conduct business with or on behalf of us. We may in the future discover instances in which we have failed to comply with applicable laws and regulations or internal controls. If any of our employees, contractors, agents, officers or other persons with whom we conduct business engage in fraudulent, corrupt or other improper or unethical business practices or otherwise violate applicable laws, regulations or our own internal compliance systems, we could become subject to one or more enforcement actions by Peruvian or foreign authorities (including the U.S. Department of Justice) or otherwise be found to be in violation of such laws, which may result in penalties, fines and sanctions and in turn adversely affect our reputation, business, financial condition and results of operations.

The climatic phenomenon El Niño and other natural phenomena such as earthquakes and floods may have a material and adverse effect on us.

Peru has experienced natural phenomena in the past such as earthquakes, other geologic events and flooding. A major earthquake could damage the infrastructure necessary for our operations. In addition, increased rainfall from the weather phenomenon known as “El Niño,” which typically occurs every two to seven years, can contribute to flooding and mudslides, which could damage roads and highways providing access to our facilities. Peru has also experienced droughts caused by low rainfall. If such events occur in the future, we may suffer damage to, or destruction of, properties and equipment, or losses not covered by our insurance policies, as well as temporary disruptions to our services, which may materially and adversely affect us. If a significant number of our employees were affected by a natural disaster, our ability to conduct business could be impaired.

22

Factors Relating to Peru

Political conditions in Peru including confrontations between different branches of government may have an adverse impact on our and Cerro Verde’s businesses.

All of our and Cerro Verde’s operations are conducted in Peru. Accordingly, our and Cerro Verde’s business, financial condition or results of operations could be affected by changes in economic or other policies of the Peruvian government or other political, regulatory or economic developments in Peru.

Peru has experienced political instability from time to time, spanning a succession of regimes with differing economic policies and programs. Although Peru has been widely considered a stable democracy in recent years, more recently in 2019 the country slid into a protracted political crisis when the then-President of the country (MartinVizcarra) took executive action to dissolve the Peruvian Congress and called for a new election of congressional members. After such actions, the now-former members of the legislative body voted to suspend the President for 12 months, and appointed the Vice President as interim president, who resigned from the position the following day. In January 2020, the Peruvian Constitutional Court ruled that the President’s closing of Congress was constitutional and legally valid, and new congressional elections were held that resulted in a highly fragmented Congress. Following these elections, the Peruvian executive and legislative branches have been at odds over several important economic and social measures, including initiatives to address the economic and social impact of the COVID-19 pandemic on Peru. In October 2020, a group of congressmen introduced a motion to hold impeachment proceedings against the then-standing President, as a result of allegations that he received illicit payments from construction companies when he was the governor of Moquegua between 2011 and 2014. In November 2020, Congress approved the impeachment of the then-standing President and, because Peru did not have any designated Vice President at such time, the then-President of Congress assumed the role of acting President. Following multiple protests across the country, the then-President of Congress resigned from his role of acting President, and Congress elected congressman Francisco Rafael Sagasti Hochhausler as president of Congress, and therefore as acting President.

Peru’s general elections to elect the president of the republic, two vice-presidents and all 130 members of congress for 2021-2026, were held on April 11, 2021. Of the candidates for president, Mr. Jose Pedro Castillo Terrones and Mrs. Keiko Sofia Fujimori Higuchi obtained the highest number of votes, but no candidate achieved outright majority of the votes. As a result, a presidential run-off election was held on June 6, 2021. Mr. Jose Pedro Castillo Terrones won that runoff election was elected as President. He started his term in July 2021.

After a June 2021 runoff election, Mr. Pedro Castillo was elected as President. He started his term at end of July 2021. As of today, his term has been characterized by many changes in the Ministerial Cabinets and certain instability. During this period of time, there have also been many changes inside the Ministries. One of President Castillo’s main proposals was the creation of a Constituent Assembly. This proposal has been consistently denied by the Congress, which has the power to review any attempted constitutional reform. Additionally, President Castillo initially proposed several tax reforms that involved increasing royalties for mining companies that have large operating margins. This proposal has been prevented by the Congress. Despite the initial measures proposed by President Castillo, there have been no substantial legislative changes that have been enacted to date that could materially affect our business.

However, we cannot predict the future proposals of either President Castillo or the Congress. Such proposals, if enacted, could have a material adverse effect on our business, prospectus, financial condition, results of operations or cash flows. Even if not enacted into law, political instability caused by future proposals of the President (or by other political officials in Peru) could affect the macroeconomic climate in Peru, including spurring currency volatility. Such political instability could have a material adverse effect on our business, prospects, financial condition, results of operations or cash flows.

Another example of political instability is the two impeachment motions that were presented in December 2021 and March 2022, respectively. The current government has faced significant opposition , and, as a result, two motions to impeach the president have been made. On December 7, 2021 the Congress voted on the first motion which resulted in a decision  not to impeach the president with a majority of 76 votes against the motion. Later, on March 28, 2022, the Congress voted again on impeachment, which was rejected with 54 votes against the motion.

23

Inflation, reduced economic growth and fluctuations in the Sol exchange rate may adversely affect our financial condition and results of operations.

Prior to 1994, Peru periodically experienced high inflation, slow or negative economic growth and substantial currency devaluation. The inflation rate in Peru, as measured by the Indice de Precios al Consumidor and published by Instituto Nacional de Estadística e Informática has fallen from a high of 7,649.7% in 1990 to 6.4% in 2021. Our revenues and operating expenses are primarily denominated in U.S. Dollars. If inflation in Peru were to increase without a corresponding devaluation of the Sol relative to the U.S. Dollar, our financial position and results of operations, and the market price of our Common Shares and ADSs, could be affected. Although the Peruvian government’s stabilization plan has significantly reduced inflation since 1999, and the Peruvian economy has experienced strong growth in recent years, there can be no assurance that inflation will not increase from its current level or that such growth will continue in the future at similar rates or at all.

Among the economic circumstances that could lead to a devaluation would be the decline of Peruvian foreign reserves to inadequate levels. Peru’s foreign reserves at December 31, 2021 were US$78.5 billion as compared to US$74.7 billion at December 31, 2020, as per the Banco Central de Reserva. Although actual foreign reserves must be maintained at levels that will allow the succeeding government the ability to manage the Peruvian economy and to assure monetary stability in the near future, there can be no assurance that Peru will be able to maintain adequate foreign reserves to meet its foreign currency denominated obligations, or that Peru will not devalue its currency should its foreign reserves decline.

In the past, Peru experienced significant levels of domestic terrorist activity. It is possible that a resurgence of terrorism in Peru may occur in the future, which would have a material adverse effect on the Peruvian economy and, ultimately, on us.

In the late 1980s and early 1990s, Peru experienced significant levels of terrorist activity targeted against, among others, the government and private sector. These activities were attributed mainly to two local terrorist groups, Sendero Luminoso and the Túpac Amaru Revolutionary Movement.

Both terrorist groups suffered significant defeats in the 1990s, including the arrest of their leaders, considerably limiting their activities after the 2000s. Although we believe that terrorist organizations no longer pose as significant a risk as they did in the 1980s and early 1990s, a small group of terrorists, primarily engaged in drug trafficking, still operate in remote mountainous and jungle areas in central and southern Peru. Despite the suppression of most terrorist activity, terrorist activity and the illegal drug trade continue to be key challenges for Peruvian authorities. Any violence derived from the drug trade or a resumption of large-scale terrorist activities could hurt our operations and businesses. If a resurgence of terrorism in Peru occurs, it could affect the Peruvian economy and us.

Another source of risk is related to political and social unrest in areas where mining, oil and gas operations take place. In recent years, Peru has experienced protests against mining projects in several regions around the country. On several occasions, local communities have opposed these operations and accused them of polluting the environment and hurting agricultural and other traditional economic activities. Social demands and conflicts may occur in the future which may have a material adverse effect on our business, financial condition and the Peruvian economy.

Deterioration in economic and market conditions in Latin America, Peru and other emerging market countries could affect the prices of our Common Shares and American Depositary Receipts (“ADRs”).

Although economic conditions are different in each country, the reaction of investors to developments in one country is likely to cause the capital markets in other countries to fluctuate. For example, political and economic events, such as the crises in Venezuela, Ecuador, Bolivia, Brazil and Argentina, have influenced investors’ perceptions of risk with regard to Peru. The negative investor reaction to developments in Latin America, particularly in our neighboring countries, may adversely affect the market for securities issued by countries in the region, cause foreign investors to decrease the flow of capital into Latin America and introduce uncertainty about plans for further integration of regional economies.

24

Peruvian exchange and investment control policies could affect dividends paid to holders of Common Shares and ADRs.

Peruvian law currently imposes no restrictions on the ability of companies operating in Peru to transfer foreign currency from Peru to other countries, to convert Peruvian currency into foreign currency or foreign currency into Peruvian currency or to remit dividends abroad, or on the ability of foreign investors to liquidate their investment and repatriate their capital. Before 1991, Peru had restrictive exchange controls and exchange rates. During the latter part of the 1980s, exchange restrictions prevented payment of dividends to our shareholders in the United States (the “U.S.”) in U.S. Dollars. Accordingly, should such or similar controls be instituted, dividends paid to holders of Common Shares and, consequently, holders of ADRs, could be affected. There can be no assurance that the Peruvian government will continue to permit such transfers, remittances or conversion without restriction. See “Item 10. Additional Information—D. Exchange Controls.”

Holders of our securities may find it difficult to enforce judgments against us outside of Peru.

We are organized under the laws of Peru. A significant majority of our directors and officers reside outside the U.S. (principally in Peru). All or a substantial portion of our assets or the assets of such persons are located outside the U.S. As a result, it may not be possible for investors to effect service of process within the U.S. upon us or upon such persons or to enforce against them in federal or state courts in the U.S. judgments predicated upon the civil liability provisions of the federal securities laws of the U.S. We have been advised by our Peruvian counsel that there is uncertainty as to the enforceability, in original actions in Peruvian courts, of liabilities predicated solely under the U.S. federal securities laws and as to the enforceability in Peruvian courts of judgments of U.S. courts obtained in actions predicated upon the civil liability provisions of the U.S. federal securities laws.

Factors Relating to the Common Shares and ADSs

The concentration of our capital stock ownership with certain members of the Benavides Family may limit our stockholders’ ability to influence corporate matters.

As of March 31, 2022, two of our directors (and their families), Roque Benavides and Raul Benavides (who transferred his shares to his children), all of which are members of the immediate and extended family of the late Alberto Benavides de la Quintana, our founder and former Chairman (collectively, the “Benavides Family”) held an aggregate of 10.92% of Buenaventura’s outstanding share capital (including outstanding Common Shares and investment shares with a nominal (par) value of ten Peruvian Soles per share, which do not entitle their holders to voting rights (“Investment Shares”)). In addition, certain other members of the Benavides Family are believed to hold a significant number of our Common Shares in aggregate. While the Benavides Family is not, to our knowledge, acting together as a group to vote their Common Shares, there can be no assurance that the Benavides Family will not, in the future, form a group for the purpose of voting their Common Shares or exerting influence over the management and policies of Buenaventura. Because of the significant aggregate ownership interest held by individual members of the Benavides Family, the Benavides Family could have the power to elect a significant number of the outstanding directors and exercise significant influence over the outcome of substantially all matters to be decided by a vote of shareholders.

In addition, under the terms of the amended and restated deposit agreement dated May 3, 2002 (as further amended and restated as of November 12, 2003, the “Amended and Restated Deposit Agreement”), among us, The Bank of New York Mellon (formerly The Bank of New York), as depositary, or the “Depositary”, and the owners and beneficial owners of ADSs, or the Amended and Restated Deposit Agreement, relating to our ADSs, if holders of ADSs do not provide the Depositary with timely instructions for the voting of Common Shares represented by such ADRs, the Depositary will be deemed to be instructed to give a person designated by us, which could be a member of the Benavides Family, a discretionary proxy to vote such shares, unless we inform the Depositary that we do not wish such proxy to be given.

Shareholders’ rights under Peruvian law may be fewer and less well-defined than shareholders’ rights in other countries, including the U.S.

Our shareholders have fewer and less well-defined rights under applicable Peruvian law than they might have as shareholders of a corporation incorporated in a jurisdiction of the U.S. or certain other countries. For example, Peruvian law does not provide for proceedings by which non-controlling shareholders may file class action lawsuits or shareholder derivative actions against controlling shareholders or officers and directors, and the procedural requirements to file shareholder actions in Peru differ from those of the U.S. As a result, holders of our shares may face difficulty enforcing their rights.

25

U.S. securities laws do not require us to disclose as much information to investors as a U.S. issuer is required to disclose, and you may receive less information about us than you might otherwise receive from a comparable U.S. company.

The corporate disclosure requirements applicable to us may not be equivalent to the requirements applicable to a U.S. company and, as a result, you may receive less information about us than you might otherwise receive in connection with a comparable U.S. company. We are subject to the periodic reporting requirements of the United States Securities Exchange Act of 1934, as amended, or the Exchange Act, that apply to “foreign private issuers.” The periodic disclosure required of foreign private issuers under the Exchange Act is more limited than the periodic disclosure required of U.S. issuers.

A sale of a substantial number of shares by the Benavides Family could have an adverse impact on the price of our Common Shares and ADSs.

The sale of a substantial number of our shares by members of the Benavides Family, or a market perception of the intention of members of the Benavides Family to sell a substantial number of shares, could materially and adversely affect prevailing market prices for the Common Shares and ADSs. There is no contractual restriction on the disposition of shares of our share capital by our shareholders, including the Benavides Family. Furthermore, under the Ley General de Sociedades Peruanas, or “Peruvian Companies Law,” any restriction on the free sale of shares in a sociedad anónima abierta (publicly held corporation) such as we are, is null and void.

Holders of ADSs may be unable to exercise preemptive rights and accretion rights available to the Common Shares underlying the ADSs.

Holders of the ADSs are, under Peruvian law, entitled to exercise preemptive rights and accretion rights on the Common Shares underlying the ADSs in the event of any future capital increase by us unless (x) the increase is approved, expressly stating that the shareholders have no preemptive rights to subscribe and pay for the Common Shares to be issued in such increase, by holders of Common Shares holding at least 40% of the Common Shares at a properly called meeting with a proper quorum and (y) the increase is not designed to improve directly or indirectly the shareholding of any shareholder. However, U.S. Holders (as defined herein) of ADSs may not be able to exercise through the Depositary for the ADSs the preemptive rights and accretion rights for Common Shares underlying their ADSs unless a registration statement under the Securities Act of 1933, as amended, or the “Securities Act,” is effective with respect to such rights or an exemption from the registration requirement thereunder is available. Any such rights offering would have a dilutive effect upon shareholders who are unable or unwilling to exercise their rights. We intend to evaluate, at the time of any rights offering, the costs and potential liabilities associated with any registration statement as well as the associated benefits of enabling the holders of ADSs to exercise such rights and will then make a decision as to whether to file such a registration statement. Therefore, no assurance can be given that we will file any such registration statement. To the extent that holders of ADSs are unable to exercise such rights because a registration statement has not been filed and no exemption from such registration statement under the Securities Act is available, the Depositary will, to the extent practicable, sell such holders’ preemptive rights or accretion rights and distribute the net proceeds thereof, if any, to the holders of ADSs, and such holders’ equity interest in us will be diluted proportionately. The Depositary has discretion to make rights available to holders of ADSs or to dispose of such rights and to make any net proceeds available to such holders. If, by the terms of any rights offering or for any other reason, the Depositary is not able to make such rights or such net proceeds available to any holder of ADSs, the Depositary may allow the rights to lapse.

ITEM 4.Information on the Company

In this Item 4, we present information first with respect to Buenaventura. We previously presented information with respect to Yanacocha; however, as of the filing of the report on Form 20-F, Yanacocha has been classified on our Consolidated Financial Statements as an asset held for sale as outlined in Note 1(e) and as such is not discussed here.

BUENAVENTURA

A.History and Development

Overview

We are Peru’s largest publicly traded precious metals company in terms of market capitalization and we are engaged in the exploration, mining and processing of gold, silver, copper and (to a lesser extent) other metals in Peru. We currently operate the Orcopampa, Uchucchacua, Julcani and Tambomayo mines and have controlling interests in three other mining companies that operate the Colquijirca-Marcapunta, Coimolache and La Zanja mines. We also own an electric power transmission company, a hydroelectric plant and a processing plant, as well as non-controlling interests in several other mining companies, including a significant ownership interest in Cerro Verde, a Peruvian company that operates a copper mine located in the south of Peru. For the year ended December 31, 2021, our consolidated sales were US$900.5 million and our consolidated net loss was US$262.8 million.

Discontinued operations. During 2020, we sold our Mallay mining unit which was previously classified as discontinued during 2019. During December 2021, Buenaventura management reclassified its negative investment held in Minera Yanacocha S.R.L for US$264,838,000 as available for sale and recognized it as a discontinued operation in the consolidated income statement for the years 2019, 2020 and 2021. See Note 1(e) and Note 2.4(w) to the Consolidated Financial Statements. On February 7, 2022, Buenaventura entered into definitive agreements to sell the entirety of its interest in Yanacocha for cash consideration of $300,000,000 to Newmont, as well as contingent cash payment linked to (i) production of the Sulphides Project that Newmont plans to develop at Yanacocha and (ii) potential future increases in mineral prices. Collectively, such contingent payments can potentially amount to an additional $100,000,000. On February 8, 2022, Newmont paid us the initial $300,000,000 cash consideration owned. Due to this transaction, we have classified Yanacocha as an asset held for sale on our Consolidated Financial Statements. As of December 31, 2021, we have classified four mining units as units with discontinued operations: Yanacocha, Mallay, Poracota and Shila-Paula.

The table below summarizes the total production and our equity share of production for the Orcopampa, Uchucchacua, Julcani, Tambomayo, El Brocal, La Zanja, Coimolache, Yanacocha and Cerro Verde mines for the year ended December 31, 2021:

History

During the first several decades of our operations, we focused on the exploration and development of silver mines in Peru, including our Julcani, Orcopampa and Uchucchacua mines. Beginning in the early 1980s, we began to explore for gold and other metals in Peru, in order to diversify our business and reduce our dependence on silver. We expanded our mineral reserves through property acquisition and intensive exploration programs which were designed to increase reserves and production of gold. We also conducted exploration leading to the discovery of gold mineralization and subsequent production of gold at our Orcopampa, La Zanja, Breapampa and Tambomayo mines. In addition, we made significant equity investments in Yanacocha, which operates an open-pit gold mine in Peru, Cerro Verde, which operates an open-pit copper mine in Peru, and Coimolache, which owns the Coimolache gold mine that we operate. As a result of these initiatives, the majority of our revenues are now derived from the production of gold, silver and copper.

Business Strategy

Our strategy is to sustain our position as Peru’s largest, publicly traded gold and silver mining company by expanding our reserves and production. We are currently engaged in an active exploration and mine development program and participate in several mining exploration projects with Newmont Mining, Southern Copper Corporation, Corporación Aceros Arequipa S.A. and Compañía de Minas Caudalosa S.A.C. In addition, we seek to increase the efficiency and capacity of our mining operations. We are aware of our social and environmental responsibilities and aim to excel in the prevention, mitigation and rehabilitation of mining-related disturbances.

Maintaining an Active Exploration Program

During the years ended December 31, 2021, 2020 and 2019, we spent US$11.3 million, US$8.5 million and US$11.9 million, respectively, on “exploration in non-operating areas” and US$56.4 million, US$28.0 million and US$44.2 million, respectively, on “exploration in operating units.” Our “exploration in non-operating areas” were mainly focused on the Emperatriz and Marcapunta exploration projects. Our “exploration in operating units” were mainly focused in the Colquijirca, Orcopampa, Uchucchacua and Tambomayo units.

In 2022 we intend to invest approximately between US$50 and US$60 million in exploration in operating units (mainly in Tambomayo, Orcopampa, Uchucchacua and El Brocal) and between US$20 and US$30 million in exploration in non-operating areas.

Participation in Mining Exploration Agreements

In addition to managing and operating precious metals mines, we participate in mining exploration agreements with mining partners to reduce risks, gain exposure to new technologies and diversify revenues to include other base metals, such as copper and zinc. See “B. Business Overview—Exploration.” We believe that maintaining our focus on mining operations complements our partnership strategy because the engineering and geological expertise gained from such operations enhances our ability to participate in, and contribute to, those projects.

Orcopampa

Location and means of access

The Orcopampa mine is located in the province of Castilla, department of Arequipa, approximately 1,350 kilometers southeast of the city of Lima, at an altitude between 3,800 and 4,500 meters above sea level. There are two routes of access to the property: (1) through Peru’s Panamerican Highway starting in Lima and continuing to the city of Arequipa for a total distance of 319 kilometers from Orcopampa; and (2) the route between Arequipa and Aplao-Viraco for a total distance of 333 kilometers. The Orcopampa mine is also accessible through a commercial flight from Lima to Arequipa.

History

The first mining operations date back to colonial times. The district was abandoned from 1842 until 1910, when the Orcopampa Mining Union was formed to continue mining. In 1960, we became interested in the area, and in 1962, exploration began in Orcopampa, with work resuming in the Tudela area and studies in Manto. The results of our initial work concluded with the signing of a lease agreement with the Orcopampa Mining Union and consequently with the construction of a 300-ton concentrator plant, which began operating in 1967 under an agreement with the Orcopampa Mining Union for royalties. We have maintained our operations at the site since that date.

29

Title, leases and options

The Orcopampa mine is wholly owned and operated by Buenaventura. We lease the rights to the mining concessions of Orcopampa from a group of private investors. This lease, which expires in 2043, requires us to pay 10% of production value, subject to certain conditions. Operations began at the Orcopampa mine in 1965. In 2021, we made lease payments of US$7.0 million. We operated Orcopampa as a silver mine until the late 1990s, when we also began to mine gold-bearing veins.

Mineralization

The Orcopampa mine consists of an epithermal gold telluride deposit, hosted into lava flows and domes of Sarpane complex (calc-alkaline to high potassium), of early Miocene to Holocene, which forms part of the tertiary metallogenic belt of Southern Peru (Au-Ag).

Operations and infrastructure

Mining at Orcopampa is conducted underground using the mechanized bench-and-fill and cut-and-fill methods. Mine ore is processed by the carbon-in-leach method in a plant located in Orcopampa. Electric power is primarily obtained from the Peruvian national electricity grid. Water for operations at Orcopampa is obtained from a lake and local river.

The mining method in Orcopampa’s underground mine is conventional and mechanized cut and fill (Breasting), this method is used to mine ore veins thickness from 0.8 to 5m. Mining is done by us and a service provider. The equipment used for development and exploration includes single-arm jumbos, bolters, scaler and scoop loaders (4yd3). The equipment used for conventional production are jacklegs, micro-electrical scoops (0.5-2yd3) and for mechanized are single-arm jumbos and diesel scoops loaders (2-4yd3). Ore haulage to surface is done with 20 and 35 m³ tipper trucks and 40m³ loading pocket in Nazareno’s and Prometida’s Shaft. Ore is taken to the process plant with 35 m³ tipper trucks.

Production

The Orcopampa mine is in the production stage and has a treatment plant capacity of 2,250 tones of ore per day. The table below summarizes the Orcopampa mine’s concentrate production, metal contained in concentrates produced and average grades for the periods indicated. Production in 2021 was significantly higher than 2020 due to the higher volume of ore treated. This was due to the fact that in 2020, our operations were suspended from March to June due to of government measures related to COVID-19.

2. The total Mineral Resources dated from December 31, 2021 considered an ownership basis of 100%.

In comparison to 2020, Orcopampa’s Mineral Resources show a decrease, mainly due to the application of new criteria used under S-K 1300, which has downgraded Measured Mineral Resources and Indicated Mineral Resources. This was partially offset by the inclusion of new veins (R4, R5 and R6), enabling Orcopampa to add Indicated Mineral Resources and Inferred Mineral Resources to the inventory

Uchucchacua

Location and means of access

The Uchucchacua mine is wholly owned and operated by Buenaventura. Operations began in 1975 and Uchucchacua remains our largest single source silver production. Uchucchacua is located in the province of Oyón, in the department of Lima, approximately 265 kilometers northeast of the city of Lima at an altitude of between 4,000 and 5,000 meters above sea level. The mine site is accessible through the Panamericana Norte highway, following the Lima - Huacho - Sayán - Churín - Oyón - Uchucchacua route for a distance of 283 kilometers.

History

Uchucchacua is a silver deposit in the central highlands discovered during the viceroyalty. Evidence of this are the many Spanish workings in the areas of Nazareno, Mercedes, Huantajalla and Casualidad. The mines passed into the hands of the Jungbluth, who continued with small scale works and even mined ore in Uchucpaton and Otuto, where there are vestiges of old “mills”.

32

At the beginning of 1960, Cia. de Minas Buenaventura started prospecting-exploration works in the area. Initial conditions were difficult as there was no road between Oyón and Chacua road until 1965, and the road was only later extended to Yanahuanca. From 1969 to 1973, Buenaventura installed a pilot plant that initially treated ores from the Socorro and Carmen mines. Satisfactory results led to the installation of an industrial plant in 1975, which currently has a treatment capacity of 4,200 metric tons per day. Currently, the Socorro, Carmen and Casualidad mines are operating. The Huantajalla area mine is also operating, though to a lesser extent.

Title, leases and options

The Uchucchacua mining unit, including Yumpag, comprises 29 mining concessions and one beneficiation concession (concentrator). These 29 concessions represent the area of mines and exploration projects. Mining and exploration activities are carried out within these mining concessions. Uchucchacua’s concessions have a total area of approximately 43,050 hectares.

Mineralization

The Uchucchacua mineral structures are hosted by Mesozoic limestone of the Jumasha Formation and are classified as a mesothermal polymetallic deposit of silver-lead-zinc with important contents of manganese. The main mineralized structures are veins and ore bodies with high-grade silver content.

Operations and infrastructure

Mining at Uchucchacua is conducted underground and utilizes the mechanized bench-and-fill and cut-and-fill methods. Ore is processed at a mill located at Uchucchacua. The mill has a rated capacity of 4,200 tons per day and utilizes differential flotation to obtain a lead-silver concentrate and a zinc concentrate, using two circuits of 3,000 tons per day and 1,200 tons per day respectively. Electric power is obtained from the Peruvian national electricity grid, a hydroelectric plant and a diesel generator. Water for operations at Uchucchacua is obtained from three local lakes.

During 2021, the manganese sulfate plant of Rio Seco treated 14,179.3 tons of concentrates from the Uchucchacua mine, with 62.3 ounces per ton of silver, 7.5% lead and 28.1% manganese. Following treatment, 7,232.87 tons were obtained, with 110.9 ounces per ton of silver, 13.19% lead and 1.52% manganese. This process also allowed for the production of 9,408.51 tons of sulfuric acid of 98.3% purity and 12,362.8 tons of commercial grade manganese sulfate monohydrated.

33

Production

The Uchucchacua mine is in the production stage and has a treatment plan capacity of 4,100 tons of ore per day. The table below summarizes the Uchucchacua mine’s concentrate production, metal contained in concentrates produced and average grades for the periods indicated. Production in 2021 was significantly lower than in 2020 due to a lower volume ore treatment, since, in 2021, operations were suspended in September.

Julcani

Location and means of access

Julcani is an underground mine that is wholly owned and operated by us that we acquired in 1953 as our first operating mine. Julcani is located in the province of Angaraes, in the department of Huancavelica, approximately 500 kilometers southeast of Lima at an altitude between 4,200 and 5,000 meters above sea level. There are two routes to access the mine site, both departing from Lima: (1) a first road starting in Lima and continuing to La Oroya followed by Huancayo and Huancavelica for a total distance of 444 kilometers; and (2) a second road starting in Lima and continuing to Pisco and then through Huancavelica which is 45 kilometers from the property for a total distance of approximately 499 kilometers.

History

The mining district of Julcani has been known since colonial times. Between 1936 and 1945 the Swiss-Peruvian Julcani Mining Company mined the veins on an industrial scale. The mine was then worked by the Cerro de Pasco Corporation until 1951. In 1953, the Buenaventura Mining Company was founded and has worked the Julcani mines until today, more than 68 years later.

Title, leases and options

The Julcani mining unit, comprises six mining concessions and one beneficiation concession (concentrator). These six concessions represent the area of mines and exploration projects. Mining and exploration activities are carried out within these mining concessions. Julcani’s concessions have a total area of approximately 11,566 hectares.

Mineralization

Julcani is a large polymetallic deposit in Central Peru, which principally produces silver that presents mainly as sulpho-salts in many mineralogically complex veins. They are hosted in dacite domes, tuffs, breccias and other tertiary volcanic rocks.

Operations and infrastructure

Ore is processed by bulk flotation to obtain a concentrate of silver-lead-copper-gold. The plant has a rated capacity of 585 tons per day. Water for operations in Julcani is obtained from mine drainage (that must be previously treated with lime), from seasonal streams and a small lagoon.

The mining method used in this operation is cut and fill, for which the primary equipment employed are pneumatic shovels, and locomotives. The mine is currently deepening the mine at level 710 operating with synergistic equipment such as electric shovels, jumbo jets and battery powered locomotives.

Electric power for the site is generated by two hydroelectric plants, Huapa and El Ingenio.Power is also provided by the Peruvian national electricity grid which Julcani is connected to.

36

Production

The Julcani mine is in the production stage and has a treatment plant capacity of 500 tons of ore per day. The table below summarizes the Julcani’s mine’s concentrate production, metal contained in concentrates produced and average grades for the periods indicated. Production in 2021 was significantly higher than 2020 due to the higher volume of ore treated. This was primarily due to the fact that in 2020, our operations were suspended from March until August as a result of the impact of government measures related to COVID-19.

In comparison to 2020, Julcani’s Mineral Resources have increased, mainly due to positive results from explorations.The explorations developed in the different levels of the mine, mainly 610, 510 on the veins: Leyci, Mirian, Santa Fe, Leonor, etc., have had a positive impact on the increase of resources and reserves in Ag. This contributed to the increase of resources and reserves in Ag metallic content. Additionally, the development of the 710 level (which is the deepest level) in the West sector, contributed to the increase of inferred resources and potential.

Tambomayo

Location and means of access

The Tambomayo mine is located in the province of Caylloma, Arequipa region, at an altitude between 4,550 and 5,000 meters above sea level. There is one route of access to the property through Peru’s Panamericana Highway starting in Lima and going to the city of Arequipa for a total distance of 764 kilometers. Between Arequipa and Tambomayo, there is a 300-kilometer road along Cañahuas-Sibayo-Caylloma-Talta Huarahuarco. The site is also accessible through a commercial flight from Lima to Arequipa.

History

Between 1990-2004 the mining company Hochschild developed several exploration campaigns in the Surihuire mountain without any success. For the years 2006-2007, CEDEMIN SAC (Shila-Paula) carried out the procedures to delineate the high zones of the eastern part of the Molloco River, and when they obtained the concessions, they named it Tuyuminas.

In 2008, exploration work began, evidencing a prominent outcrop that showed a silica-quartz outcrop, which had continuity in length, known today as the Mirtha Vein. After an aggressive exploration campaign in which geological mapping and sampling were developed, we obtained robust geological information by 2009, which included geochemical analysis of the Mirtha vein sector, which led us to begin a drilling campaign at the site in late 2009. Between January and May 2010, the results of the first drill holes were obtained, validating the continuity of the structure at depth.

Finally, in 2012, Compañía de Minas Buenaventura acquired directly 100% of the Tuyuminas concessions, changing its name to Tambomayo

Title, leases and options

The Tambomayo mining unit comprises seven mining concessions and one beneficiation concession (concentrator). These seven concessions represent the area of mines and exploration projects. Mining and exploration activities are carried out within these mining concessions. Tambomayo’s concessions have a total area of approximately 29,566 hectares.

Mineralization

Tambomayo is an underground mine that is wholly owned and operated by us. It is considered an epithermal deposit with quartz veins and mineralization mainly of gold and silver with important contents of lead and zinc.

Operations and infrastructure

The underground works on the main Mirtha and Paola veins and diamond drilling carried out to date show an economic mineralization that deepens up to approximately 900 meters, and it expands over 900 horizontal meters (1,500 horizontal meters as a quartz system), increasing the size of the economic mineralization area to explore. Mining at Tambomayo is conducted underground and utilizes the mechanized bench-and-fill and cut-and-fill methods.

39

The mining method in Tambomayo’s underground mine is sub-level stopping and mechanized bench and fill. This method is used to mine massive ore body (30 meters between sublevels and a 10-meter stope span). We conduct the ore mining while horizontal labor is provided by a service provider. The equipment used for development and exploration includes single-arm jumbos, bolters, scalers and scoop loaders (4-6yd³). The pieces of equipment used in stopes are Simbas (Bolting Cable and Production) and scoops with remote control (6-7yd³). Ore haulage to surface is done with 35 m³ tipper trucks. Ore is taken to the process plant with 35 m³ tipper trucks.

Tambomayo is connected to the Peruvian electricity grid and water for its operations comes from the damming of a stream with seasonal variations in flow.

Production

The Tambomayo mine is in the production stage and has a treatment plant capacity of 1,500 tons of ore per day. The table below summarizes the Tambomayo mine’s concentrate production, metal contained in concentrates produced and average grades for the periods indicated. Production in 2021 was significantly higher than 2020 due to higher ore treated, since in 2020 operations were suspended from March to June due to the impact of government measures related to COVID-19.

El Brocal was founded in 1956 and is engaged in the extraction, concentration and sale of concentrates of polymetallic minerals—mainly zinc, copper, lead and silver. Our aggregate direct and indirect equity interest in El Brocal was 61.43% as of December 31, 2021.

Title, leases and options

The El Brocal mining unit comprises one mining concession, one mining transport concession and one beneficiation concession (concentrator). These concessions represent the area of mines and exploration projects. Mining and exploration activities are carried out within these mining concessions. El Brocal’s concession has an extension of approximately 32,819 ha.

Mineralization

El Brocal produces zinc, lead and silver concentrates from the Tajo Norte mine and copper concentrates from the Marcapunta mine. The Colquijirca mine consists of three important polymetallic deposits: (1) Tajo Norte–Smelter, which contains zinc, silver, lead, copper and gold; (2) Marcapunta, which contains an auriferous mineralization in breccia oxides and an arsenic copper enargite mineralization as a continuation of the mineralized mantles of the Marcapunta mine; and (3) San Gregorio, which contains zinc.

Operations and infrastructure

The Tajo Norte (Colquijirca) and Marcapunta mines primarily rely on a power line connected to the Peruvian national electricity grid, and the ore from the mines is primarily treated in two plants. In 2021, for the period in which the plants were able to operate without the interference of COVID-19 restrictions, the two plants treated on an average of 15,000 tons per day.

As in 2021, in 2022, El Brocal continued to focus on optimizing Marcapunta’s mining method, while also seeking the optimization of productivity and production costs, as well as accelerating the conversion of resources to reserves.

The mining method in the Marcapunta mine (Underground) is sub-level stopping with long pillars and backfill. This method is used to mine the Copper mantle that has an ore thickness up to 60 meters. Mining is made by contactor with its own equipment. The equipment used for development are 2 arm jumbos with 6 yd3 underground loaders. The equipment used for production includes S7 top hammer Simbas with 6 yd3 underground loaders with remote control. Ore haulage to surface is done with 12 m³ and 15 m³ tipper trucks. Ore is taken to the process plant with 15 m³ and 20 m³ tipper trucks. In 2022, we are planning to use 9 yd3 underground loaders and in the hole hammer. Bench height is also being optimized in new zones from 20 meters to 30 meters.

Meanwhile, the mining method in Tajo Norte is an open pit. It is a conventional truck and shovel operation, through a contractor. The height of a workbench is 6 meters and the equipment used includes DM45 and DML drilling rigs. Loading is by hydraulic excavators EC950E (5.6 m³) and 374D (4.6 m³) and hauling is by G500 B8X4 trucks (24.5 m³). For 2022, we are planning to use eight excavators and 48 trucks. To maximize mine production, Tajo Norte mine employs a fleet management system that supports the transmission and receipt of data across the mobile fleet, and supports the collection of data which is input directly by equipment operators.

Production

The El Brocal mine is in the production stage and has a treatment plan capacity of 20,000 tons of ore per day. The table below summarizes the El Brocal Zinc-Lead-Silver zone of Tajo Norte (Colquijirca) mine’s concentrate production, metal contained in concentrates produced and average grades for the periods indicated. Production in 2021 was significantly lower than 2020 due to the lower volume of ore treated. The decrease was due to reserves write off from phase 6 (a previously mined area) and delays in stripping of phase 12. This decrease was partially offset by copper production from the open pit.

La Zanja

Location and means of access

The La Zanja mine is located in the district of Pulan, province of Santa Cruz, department of Cajamarca, 48 kilometers northwest of the Yanacocha gold mine, at an average altitude of 3,500 meters above sea level. Access to the operation site is available through the Panamericana Norte highway from Lima to Cajamarca followed by a departmental road network that leads to Pulán where the mining concession is located. La Zanja is operated by us.

History

In 1990, La Zanja was part of the northern Peru project established between Buenaventura and Newmont, covering 83,900 hectares in the Yanacocha volcanic belt by Buenaventura Ingenieros S.A. In addition to La Zanja, other copper and gold prospects were discovered in the La Huaca, Peña Verde and Galeno zones. In 1997, a total of 3,800 m of diamond drilling was completed at La Zanja.

After many years, in August 2010, the Peruvian government granted permits to Buenaventura to commence metallurgical operations at La Zanja. In September of 2010, Buenaventura and Newmont began production at La Zanja. The mine was expected to produce 100,000 oz Au per year over a seven-year mine life.

Title, leases and options

The operation area has mining concessions assigned to La Zanja, and the surrounding area also shows the presence of other concession holders such as Buenaventura, Newmont and several other companies. The La Zanja mining unit comprises 43 mining concessions and one beneficiation concession (concentrator). These 43 concessions represent the area of mines and exploration projects. Mining and exploration activities are carried out within these mining concessions. La Zanja’s concessions have an extension of approximately 27,414 hectares.

Mineralization

La Zanja is located within a large area of hydrothermal alteration, mainly related to epithermal gold deposits in high sulphidation environments, in addition to some bonanza Au vein epithermal systems, Cu-Au transitional epithermal-porphyry, and breccias pipe Cu-Au-Mo. We have two-ore deposits in production in oxide material: San Pedro Sur and Pampa Verde.

Operations and infrastructure

During 2021, the operation focused on the San Pedro Sur and Pampa Verde open pits. Reinterpretation geological exploration was also carried out in projects with resources and reserves. The operation is carried out with outsourced equipment, which includes loading equipment of 2.4–4.7 m³ and hauling equipment of 20-22 m³. The average material moved is 11.7 kilo tons per day.

Mining operations are conducted through the open-pit method. The plant utilizes a carbon-in-column circuit as well as a Merrill-Crowe circuit to recover gold from heap leach operations. The gold laden carbon is then transported to Coimolache to be processed into doré bars.

In 2021, a total of 18,331 meters of diamond drilling in the Cu-Au exploration project Emperatriz, and the extensions of the corridors Olga and Isabel were confirmed.

54

Production

The La Zanja mine is in the production stage and has a treatment plan capacity of 20,000 tons of ore per day. The table below summarizes the La Zanja mine’s doré bars production, metal contained in doré bars produced and average grades for the periods indicated. Production in 2021 was significantly higher than in 2020 due to a higher volume of ore treated. The increase was primarily due to the fact that in 2020, our operations were suspended from March to June due to the impact of government restriction imposed in connection with COVID-19.

Coimolache’s history is linked from its origins to the Hualgayoc Mining District, as a historic mining center in northern Peru. The first work in the area was recorded from 1969 to 1971 by the British Geological Survey (BGS) who carried out sediment sampling in the region and the district and identified seven anomalies in the Tantahuatay and Sinchao creeks. From 1970 to 1991 Cia. Minera Colquirrumi S.A., developed exploration and exploitation works in the Hualgayoc district.

The first works during SPCC’s administration involved geological mapping, rock and soil geochemistry in trenches and test pits. From 1994 to 1998 they carried out 27,411 meters of diamond drilling between the sectors of Tantahuatay, Mirador, Ciénaga and Peña de las Águilas as Calera Orbamas S.A. (the company’s name was CMC at that time).

BVN took over the administration in 1999 and carried out underground exploration for oxides with two tunnels in the deposits of Tantahuatay 2 (BISA)and Cienaga Norte, respectively and carried out diamond infill drilling in the deposits of Tantahuatay 2 (BISA) and Ciénaga Norte, Mirador Norte (CEDIMIN) during 2002 and from 2006 to 2007, for a total of 6,063 meters. The project is part of the final exploration plans of Cia. Minera Colquirrumi of the Buenaventura group.

CMC began the pre-feasibility stage in 2007, the EIA was completed with a public hearing in Hualgayoc in 2008, and construction began in 2009. The oxide operation started in June 2011.

Title, leases and options

The area of the concessions in which CMC performs exploitation and beneficiation activities totalizes 16,713.52 has (SRK, 2019) and the titleholder is Compañía Minera Coimolache S.A.

58

There are 26 mining concessions and one beneficiation concession (beneficiation plant). These 26 concessions cover the area of the mines and the exploration projects. The mining operation and the explorations are conducted within the mining concessions. SRK indicates that all the mining reserves and resources presented in this report are located within these concessions controlled by Compañía Minera Coimolache.

Mineralization

Geologically, the Coimolache ore deposits are located in a sequence volcano-magmatic hydrothermal, predominantly linked to the regional mineralized sector northern of Peru.

Coimolache consists of several areas of epithermal Au-Ag mineralization, contained in oxide material. Below the oxides level of the Cerro Tantahuatay area, there is a significant resource of copper, gold and silver associated to pyrite-enargite-chalcopyrite (sulphides), which are present as disseminations and fracture fillings associated with an epithermal-porphyry transitional zone, breccias bodies multiphases, and porphyry intrusives.

Operations and infrastructure

During 2021, the operation was focused on the Tantahuatay 2 and Ciénaga Norte areas. Reinterpretation geological exploration was also performed at projects with resources and reserves. The operation is carried out with outsourced equipment, which includes loading equipment of 5.6-3.6 m³ and hauling equipment of 15-22 m³. The average material moved is 49.3 kilo tons per day.

Production

The Coimolache mine is in the production stage and has a treatment plan capacity of 30,000 tons of ore per day. The table below summarizes the Coimolache mine’s doré bars production, metal contained in doré bars produced and average grades for the periods indicated. Production in 2021 was slightly lower than in 2020 due to a lower volume of ore treated since the leach PAD was restricted because the environmental permit approval was delayed during the COVID-19 pandemic.

The Coimolache Mineral Resources estimates in the table above were estimated with three independent block models that were prepared for each of Tantahuatay’s deposits: Tantahuatay, Cienaga and Mirador, which are open-pit operations. 3D geological model was generated by Buenaventura for different types of data (mainly drill holes, blastholes, working mapping and section interpretation) to constrain and control mineralization and its domains. Drilling data from cores were combined into geological structures. Gold and silver grades were interpolated into block models for the different deposits. Mine zones were modeled using ordinary Kriging in each deposit. The results were visually validated, through various statistical comparisons.Additional information regarding the Mineral Resources estimates provided can be found in Section 11 of the Coimolache Technical Report Summary.

Cerro Verde

Location and means of access

We hold a 19.58% interest in Cerro Verde, which operates an open-pit copper and molybdenum mining complex located 20 miles southwest of Arequipa, Peru. The site is accessible by paved highway. The Cerro Verde mine has been in operation since 1976, and was previously owned by the Peruvian government before its privatization in 1993. Freeport-McMoRan Inc. holds a majority interest in Cerro Verde.

History

First activities of the Cerro Verde porphyry copper deposit date back to the late 1800s when artisanal mining produced high-grade oxide ore. In 1917 Anaconda Copper Mining Company acquired the property and operated intermittently until 1970 when the property was nationalized. Minero Perú S.A., a government-controlled mining company, commenced mining and processing of ore with a SX/EW plant and pilot concentrator plant in 1977. The SX/EW plant was among the first in the world to be commissioned.

Minero Perú S.A. sold Cerro Verde to Cyprus Climax Metals Company in 1994. By 1996, remaining ownership included Buenaventura and a variety of individual investors trading their shares on the Lima Stock Exchange. Shortly thereafter, Cyprus invested in improvements to the leach process production. Cyprus Climax Metals Company was acquired by the Phelps Dodge Corporation (PDC) in 1999. By 2004, the SX/EW plant capacity was at 200 million pounds of copper cathode per year (Bernal and Velarde, 2004).

In 2005, SMM Cerro Verde Netherlands B.V. acquired 21 percent ownership, and Buenaventura increased their ownership to 18.3 percent while PDC retained 53.56 percent as part of construction of a primary sulfide concentrator (C1). Production started in 2006, with a capacity of 108,000 metric tons of ore per day. In 2011, C1 capacity was increased to 120,000 metric tons per day following completion of various debottlenecking projects.

FCX acquired PDC in 2007. In 2007, FCX started a drilling program for deep exploration, infill confirmation, geomechanical, hydrogeological, and condemnation targets. Between 2008 and 2011, more than 200,000 meters were drilled.

Construction of new, additional concentrator facilities (C2) with a nominal capacity of 240,000 metric tons of ore per day was completed in 2016. As a result, the total Cerro Verde concentrating capacity expanded to 360,000 metric tons of ore per day. Recent production trends are exceeding the designed capacities. In 2018, ore processing capacity of C2 was increased to 288,000 metric tons of ore per day.

The Cerro Verde mine is a well-developed property currently in operation and all previous exploration and development work has been incorporated where appropriate in the access and operation of the property.

Title, leases and options

In Peru, mining rights through claims and concessions are regulated by Peru’s General Mining Law. Cerro Verde’s major operations take place in the mining concession “Cerro Verde No 1, 2, y 3” and in the Cerro Verde processing facilities concession “Cerro Verde Beneficiation Plant”, (hereinafter the “Beneficiation Plant”). Sociedad Minera Cerro Verde is the titleholder of the entire mining concession, all other concessions, and areas where the Cerro Verde operations are located. They are retained through the annual payments of rights for the concessions or the corresponding penalties for not exploiting them. Surface land is not owned; however, Supreme Decree 017-1996-AG granted mining companies surface rights of those concessions already titled by the time this regulation was passed upon formal declaration before the Peruvian Ministry of Energy and Mines (MINEM). Cerro Verde mining and main core concessions were declared and exempted from the farmland’s privatization processes. The Beneficiation Plant authorization includes the processing and recovery methods of ore entirely sourced from the mining concession.

Mineralization

The Cerro Verde mine is a porphyry copper deposit that has leachable oxide and secondary sulfide mineralization, and millable primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper “pitch.”

63

Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite and molybdenite are the dominant primary sulfides.

Operations and infrastructure

Cerro Verde’s operation consists of an open-pit copper mine, with a processing capacity of 548,500 metric tons-per-day that includes (i) concentrator facilities with a 409,500 metric ton-per-day capacity (361,500 metric tons-per-day prior to the expansion approved by the MEM during 2018), (ii) solution extraction and electrowinning (SX/EW) leaching facilities with leach copper production derived from a 39,000 metric ton-per-day crushed leach facility and (iii) a run-of-mine (ROM) leach system with a capacity of 100,000 metric tons-per-day. This SX/EW leaching operation has a production capacity of approximately 200 million pounds of copper per year.

Cerro Verde has sufficient equipment to move an average of 947,000 tons of material per day using a fleet of haul trucks. Copper cathodes and concentrate production are transported approximately 70 miles by truck and rail to the Pacific Port of Matarani for shipment to international markets.

Cerro Verde receives electrical power under long-term contracts with electric utility companies. Water for Cerro Verde’s processing operations comes from renewable sources through a series of storage reservoirs, which Cerro Verde believes will be sufficient to support its currently planned operations.

Production

The Cerro Verde mine is in the production stage and has a treatment plant capacity of 400,000 tons of ore per day. The table below summarizes the Cerro Verde mine’s concentrate production, metal contained in concentrates produced and average grades for the periods indicated. Production in 2021 was significantly higher than 2020 due to a higher volume ore treatment. This was primarily due to the fact that in 2020, operations were suspended in March due to government measures related to COVID-19.

San Gabriel

Location and means of access

The San Gabriel Project is located in the Ichuña district, in the General Sánchez Cerro Province of the Moquegua Region in southern Peru. The project is approximately 837 kilometers southeast of Lima and 116 kilometers northeast of Moquegua.

The Project can be accessed from the cities of Arequipa, Moquegua and Juliaca via a mixture of paved and unpaved roads.

History

In 2003, Minera Gold Fields Peru S.A. (Gold Fields Peru) obtained the Chucapaca, Chucapaca Norte, Orcori, Yaretapampa and Yaretapampa Sur mining concessions. In February 2007, Gold Fields Peru joint ventured the Project with Buenaventura. In 2009, Buenaventura and Gold Fields Peru formed Canteras del Hallazgo S.A.C. (Canteras del Hallazgo) as the operating entity. In 2014, Buenaventura acquired a 51% interest in Gold Fields Peru and a 100% interest in Canteras del Hallazgo, giving Buenaventura a 100% interest in the Project.

Title, leases and options

The San Gabriel Project comprises five mining concessions, covering an area of 3,467.3 hectares. Buenaventura complies with the annual payment of the obligations given by the state for the maintenance of the mining property, the license fees and, if applicable, payment of any penalties incurred. Three royalties are payable on the Ichuña 2 IMG concession.

Mineralization

The San Gabriel deposit shows many of the characteristics of an intermediate sulfidation epithermal deposit.

An inlier of folded and faulted basement Jurassic-Cretaceous siliciclastic and carbonate sedimentary rocks of the Yura Group forms a basement high in the Ichuña District. It is overlain by a cover sequence of Cenozoic (Paleogene, Neogene, and Quaternary) volcaniclastic sediments and lavas.

Mineralization is hosted in Jurassic–Cretaceous Yura Group sediments, with dark grey limestones and interbedded clastic rocks of the Gramadal Formation hosting the most continuous replacement-style alteration and mineralization. The San Gabriel deposit is approximately 3,000 meters long, 250 meters wide, and averages 170 meters in thickness. It has been drill tested to a depth of 700 m.

Operations and infrastructure

The San Gabriel Project is currently serviced by an operational 22.9 kV transmission line that was installed from the public electricity grid, servicing the mine services (1 MVA) and the Agani advance camp (650 kVA). The transmission line will continue to be used during the construction phase. Exploration activities preferentially hire labour from the local communities. During construction and mine operations, Buenaventura plans to preferentially hire qualified or unskilled personnel from the populations within the project’s area of influence, including C.C. Santa Cruz de Oyo Oyo, Maycunaca and Antajahua, and C.C. Corire and the Ichuña District. Where local labor is unavailable, hiring will be first come from the region, and only afterwards from outside the region.

The required infrastructure to support the LOM plan will include the underground mine, backfill and concrete batch plants, waste rock storage facilities, topsoil stockpile, process plant, run-of-mine (ROM) stockpile, process water ponds, mine water pond, freshwater dam, filtered TSFs (FTSF), tailings thickening and filtering platform, tailings drying platforms, temporary tailings storage area, mine operations and warehouse area, administration offices, truck, maintenance and work shops, fuel station, core shed, gatehouse, accommodation camp, sewage treatment plant, temporary waste storage area, and electrical substation. The camp capacity is based on an estimate of construction personnel and operations personnel. In operation, the camp will have a capacity of 816 people. However, during construction the capacity of some modules will be increased to support a total camp capacity of 1,440 persons.

Trapiche

Location and means of access

The Trapiche Project is located in the Apurimac region in south-central Perú and is located about 95 km south of the town of Abancay and about 8 km south of the Mollebamba village in the Antabamba Province. The location coordinates are UTM 728,672 E and 8,396,177 N. The elevation of the property and deposits range from 3,900 to 4,650 meters above sea level (masl).

Two access roads are being considered for the access to the mine site from Chunchumayo. One is termed the East Access Road begins in Chunchumayo and ends in the township of Mollocco. The other road is termed the West Access Road and begins in Chunchumayo and eventually ties into the road to Mollebamba. The main access road will be built as a joint effort by the Regional Government and the Federal Government of Peru.

History

The geological prospecting work began in 1996, extending until 2000, consisting of geochemical prospecting (stream sediments), mapping and rock geochemistry, determining Cu and Mo anomalies that motivated the continuity of the explorations. In 2001-2002, a diamond drilling campaign was completed with the execution of six drill holes (2,192.95 meters). The results were positive leading to the discovery of the Trapiche porphyry with Cu-Mo sulfide mineralization.

70

Title, leases and options

The Trapiche Project area consists of 44,098 hectares in 38 mining concessions as well as an additional 2,300 hectares with land use rights that were granted by the Mollebamba village in 2011 through an easement agreement signed with Compañía de Minas Buenaventura and El Molle Verde S.A.C.

Mineralization

The Trapiche deposit corresponds to a typical porphyry deposit with Cu and Mo mineralization, which is related to the location of the hydrothermal polyphase quartz monzonite porphyry (QMP) and Breccia Pipe, which crosscuts sedimentary sequences of Late Jurassic to Early Cretaceous age.

The mineralization is a Cu-Mo porphyry, constituted mainly by primary and secondary copper sulfides, molybdenite and to a lesser extent, copper oxide. The highest volume of sulfides is located in the Breccia Pipe, followed by the quartz monzonite porphyry, and in a lower percentage, the Cu oxides located in the western border with contact to the breccia and calc-silicate sediments, associated with the monzonite intrusive dikes.

Operations and infrastructure

The construction of a topsoil material stockpile (DMO, for its acronym in Spanish) has-been planned as part of the auxiliary facilities for the Trapiche Project, with the aim of stockpiling and saving organic soil (topsoil) recovered during the construction phase of the project for use during progressive and final closures.

Currently, the power supply for the exploration facilities is provided by generators in the Pionner Camp area with a maximum installed capacity of 460 kW and a capacity of up to 2 MW. The closest electrical substation is Cotaruse and the closest distribution line is the high voltage line that goes from Cotaruse to Las Bambas.

Mineral Reserves and Mineral Resources

The Trapiche Mineral Reserves estimates are based on the definitions for Mineral Reserves in S-K 1300 and the tables below are based on costs and modifying factors from the Trapiche mine.

Mineral Resources and Reserves

Disclosure of Mineral Resources and Reserves

The SEC amendments to its disclosure rules modernizing the mineral property disclosure requirements for mining registrants became effective on January 1, 2021. The amendments include the adoption of Subpart 1300 of Regulation S-K as promulgated by the SEC (“S-K 1300”), which governs disclosure for mining registrants S-K 1300 replaced the historical property disclosure requirements for mining registrants that were included in the SEC’s Industry Guide 7 and better align disclosure with international industry and regulatory practices.

For the meanings of certain technical terms used in this prospectus, see “Additional Information-Glossary.”

The qualified persons that have reviewed and approved the scientific and technical information contained in this annual report are identified in the footnotes to the tables summarizing the Mineral Reserves and Resources estimates. See “Information on the Company-Mining operations” below. For the meanings of certain technical terms used in this report, see “Introduction—Glossary of Selected Mining Terms.”

Presentation of information concerning Mineral Reserves

The estimates of proven and probable reserves at our mines and projects and the estimates of life of mine (LOM) included in this annual report have been prepared by the qualified persons referred to herein, and in accordance with the technical definitions established by the SEC. Under S-K 1300:

Proven Mineral Reserves are the economically mineable part of a Measured mineral resource and can only result from conversion of a measured mineral resource.

Probable Mineral Reserves are the economically mineable part of an indicated and, in some cases, a measured mineral resource.

Measured Mineral Resource is that part of a mineral resource for which quantity and grade or quality are estimated based on conclusive geological evidence and sampling. The level of geological certainty associated with a Measured Mineral Resource is sufficient to allow a qualified person to apply modifying factors, as defined in S-K 1300 (as defined below), in sufficient detail to support detailed mine planning and final evaluation of the economic viability of the deposit. Because a Measured Mineral Resource has a higher level of confidence than the level of confidence of either an Indicated Mineral Resource or an Inferred Mineral Resource, a Measured Mineral Resource may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve.

Indicated Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated based on adequate geological evidence and sampling. The level of geological certainty associated with an Indicated Mineral Resource is sufficient to allow a qualified person to apply modifying factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Because an Indicated Mineral Resource has a lower level of confidence than the level of confidence of a measured mineral resource, an indicated mineral resource may only be converted to a probable mineral reserve.

Inferred Mineral Resource is that part of a Mineral Resource for which quantity and grade or quality are estimated based on limited geological evidence and sampling. The level of geological uncertainty associated with an Inferred Mineral Resource is too high to apply relevant technical and economic factors likely to influence the prospects of economic extraction in a manner useful for evaluation of economic viability. Because an Inferred Mineral Resource has the lowest level of geological confidence of all mineral resources, which prevents the application of the modifying factors in a manner useful for evaluation of economic viability, an Inferred Mineral Resource may not be considered when assessing the economic viability of a mining project and may not be converted to a mineral reserve.

73

We periodically update our reserves and resources estimates when we have new geological data, economic assumptions or mining plans. During 2021, we performed an analysis of our reserves and resources estimates for certain operations, which is reflected in new estimates as of December 31, 2021. Reserves and resources estimates for each operation assume that we either have or expect to obtain all the necessary rights and permits to mine, extract and process mineral reserves or resources at each mine. Where we own less than 100% of the operation, reserves and resources estimates are presented in two forms, showing figures considering 100% ownership and also adjusted to reflect our ownership interest. Certain figures in the tables, discussions and notes have been rounded.

Mineral Reserves

The following table shows our estimates of Attributable Mineral Reserves for our material mining properties as of December 31, 2021. With the exception of Julcani and La Zanja (for which the reports were generated internally) the below estimates were prepared in accordance with Subpart 1300 of Regulation S-K.

Internal Control Disclosure

Buenaventura has implemented established quality assurance/quality controls (“QA/QC”). SRK, our independent consultants, review Buenaventura´s QA/QC procedures annually to ensure that those procedures follow best practices and recognized international standards for Mineral Resources and Reserves estimations. The main objective of QA/QC is to monitor and ensure the accuracy (quality) in the sampling both in the preparation phase and in the assay phase, and to verify the probable errors that could arise through the process. Additionally, QA/QC aim to identify any contamination caused by poor or deficient sampling, preparation (crushing and pulverizing) and/or assaying. Before the sample preparation phase, quality control (QC) samples are inserted at pre-determined intervals representing a percentage of the total samples. The control samples inserted in the preparation phase are coarse duplicates, fine duplicates, certified reference materials or standards, coarse blanks, and fine blanks, with the insertion distribution designed by the quality assurance/ quality control Supervisor in accordance with the protocols established for the project. The control samples help to identify some errors in the sampling, preparation and assay phases of the samples, which are been corrected by continuous monitoring and appropriate statistical analysis in order to ensure the quality of the ordinary samples. QA/QC procedures include insertion of blank and duplicate samples and insertion of certified reference materials (CRMs), blanks, and duplicates to monitor the sampling, sample preparation and analytical processes. Every mine and advanced project provides a detailed QA/QC report at least once a year. Internally, regular data verification workflows are carried out to ensure the collection of reliable data. Coordinates, core logging, surveying, and sampling are monitored by exploration and mine geologists, and verified routinely for consistency.

Capital Expenditures

Our capital expenditures during the past three years have related principally to the acquisition of new mining properties, construction of new facilities and renewal of plant and equipment, excluding cost for mine closures and rights of use asset, during a given period. Capital expenditures relating to exploration are not included in the table below and are discussed separately in “B. Business Overview— Exploration.” Our presentation of capital expenditures may not be comparable to other similarly titled measures used by other companies. Set forth below is information concerning capital expenditures incurred by us in respect of each of our principal operating mines and by category of expenditure:

We partially funded the El Brocal Expansion and the construction of the Huanza hydroelectric power plant with leasing facilities. See “Item 5. Operating and Financial Review and Prospects—Buenaventura—B. Liquidity and Capital Resources—Long-Term Debt.”

We have budgeted approximately US$190 to US$210 million for capital expenditures for 2022. We continuously evaluate opportunities to expand our business within Peru, as well as in other countries as opportunities arise, and expect to continue to do so in the future. We may in the future decide to acquire part or all of the equity of, or undertake other transactions with, other companies involved in the same business as us or in other related businesses. However, there can be no assurance that we will decide to pursue any such new activity or transaction.

B.Business Overview

We mainly produce refined gold and silver, either as concentrates or doré bars, and other metals such as lead, zinc and copper as concentrates that we distribute and sell locally and internationally. The following table sets forth the production of the Orcopampa, Tambomayo, Uchucchacua, Julcani, La Zanja and Colquijirca-Marcapunta mines by type of product for the last three years, calculated in each case on the basis of 100% of the applicable mine’s production. Production from Cerro Verde, Yanacocha and Coimolache are not included in these production figures.

(1) The amounts in this table reflect the total production of all of our consolidated subsidiaries, including El Brocal and La Zanja.

(2) Amounts exclude production from the operating mines that are classified as discontinued operations.

Exploration

We view explorations as our primary means of generating value for our shareholders, and we maintain a portfolio of active exploration projects at various stages of exploration for mineral resources in Peru. During 2021, 2020 and 2019, we spent US$11.3 million, US$8.5 million and US$11.9 million, respectively on “exploration in non-operating areas” investments and US$56.4 million, US$28.0 million and US$44.2 million, respectively on “exploration in operating units” investments mainly focused in the Tambomayo, Uchucchacua and Colquijirca mining units.

During 2022, we expect to invest approximately US$70 to US$90 million in these exploration activities.

79

Our exploration department develops programs and budgets for individual projects each year and we allocate, subject to board approval, the proper amount to fund each particular exploration program. Because of the nature of mining exploration and to maintain flexibility to take advantage of opportunities, we allocate budgeted amounts by property or project only in the case of high probability of success. We also allocate non-budgeted amounts over the course of the year to new projects that our technical team considers highly prospective.

We have active joint venture exploration agreements with other mining companies, including Southern Copper Corporation, Regulus Resources, Alianza Minerals and Minera Bateas. Additionally, we now hold 19.3% of the current outstanding shares of Tinka Resources Limited. Consequently, we have access to promising mining projects through exploration of our own mining properties as well as third-party properties while sharing the exploration and development risks with recognized partners, and increasing our exposure to new exploration technologies, while expanding our knowledge and experiences of management, geologists and engineers. In these mining exploration agreements, we may be the operator, an equity participant, the manager or a combination of these and other functions.

The following table lists our principal exploration projects in non-operating areas, our effective participation in each project, our partners with respect to each project, the total number of hectares in each project, observed mineralization of each project and the exploration expenditures for each project during 2019, 2020 and 2021.

The following is a brief summary of current exploration activities conducted by Buenaventura directly and through joint exploration agreements, which we believe represent the best prospects for discovering new reserves. There can be no assurance, however, that any of our current exploration projects will result in viable mineral production or that any of the mineralization identified to date will ultimately result in an increase in our ore reserves. Set forth below is a map of our principal exploration projects in Peru as of December 31, 2021.

Exploration Projects in Non-Operating Areas

Yumpaq. The Yumpaq project is located four kilometers northeast of the Uchucchacua mine. This project is an epithermal silver-manganese deposit hosted by Cretaceous limestone. Mineralization is structurally influenced by the Cachipampa fault, which also influences significant areas of silver mineralization at the Uchucchacua mine.

81

In 2021, we conducted an additional 6,045 meters of infill drilling in the Camila vein and 11,840 meters of exploration drilling in the Tomasa vein system which has allowed us to identify silver mineralization over 600 meters along the strike with average grade of 25 ounces of silver.

For 2022, we expect to execute an additional of 8,000 meters of drilling in the Tomasa vein. We also expect to conduct 12,700 meters of drilling to explore the southwest extension of the Camila vein and 5,000 meters of drilling to test new veins.

Trapiche. The Trapiche project is operated by Molle Verde S.A.C, which is a wholly owned subsidiary of Buenaventura. The project is located in the Apurimac region and belongs to the Andahuaylas-Yauri belt, which contains several iron, copper and gold deposits.

During 2021, the on-site metallurgy lab was completed, and 36 out of 100 column tests were started according to the feasibility plan agreed to with M³. Additionally, the environmental base-line study was completed and submitted to the relevant government authority, followed by one out of two local workshops aiming at starting the EIA by the end of the third quarter of 2022. Finally, the Pre-Feasibility study was updated and aligned with the S-K1300 pursuant to which the following reserves and resources were published:

As of December 31, 2021, Trapiche had mineral reserves of 283,200 thousand metric tons at 0.51% Cu representing 144,432 copper metric tons and mineral resources of 653,800 at 0.32% representing 209,216 copper metric tons.

San Gabriel. The San Gabriel project is wholly owned by Buenaventura. The project is located in the Moquegua region in southern Peru. This deposit is an intermediate sulfidation deposit hosted by the diatreme breccia body at the sediment-intrusive contact.

During 2021, all technical issues regarding construction permits were responded to and the “Consulta Previa” process was concluded with both communities. We received the permit on March 30, 2022. In order to mitigate the delays in the permit process, we performed engineering and procurement activities with Ausenco. Finally, the Feasibility study was updated and aligned with S-K1300 pursuant to which the following reserves and resources were published:

As of December 31, 2021, San Gabriel had mineral reserves of 14,900 thousand metric tons at 4.04 g/t Au. This represents 1.96 million ounces of gold.

Ccelloccasa. Is an epithermal vein deposit located in the Ayacucho region and consists of 13,210 hectares of mining concessions wholly owned by Buenaventura. The “Consulta previa” process was completed in both local communities. For 2022, we expect to execute 2,600 meters of diamond drilling in this vein.

Don Jorge, The Project is located in the Puno department and consists of 7,481 hectares of mining concessions and a series of polymetallic-silver rich veins. In August 2021, Direccion General de Asuntos Ambientales Mineros observed the filing of the environmental instrument. We have currently filed an appeal, and we expect a response in the second quarter of 2022.

Exploration in Operating Areas

Orcopampa. Our explorations were focused on a new vein called “Ramal 4,” which is part of the Pucara vein system. During 2021, infill drilling between the 3690 and 3540 mine level was completed. As December 31, 2021 we estimated our measured and indicated resources at 174,054 tons with an average grade of 12.4 grams of gold per ton.

Additionally, two exploration tunnels were executed at the 3540 level. We completed one in third quarter of 2021, and we expect to complete the other during the second quarter of 2022. We expect that these additional tunnels will allow us to explore five targets related to the Pucara system with diamond drilling.

Finally, we will continue exploring the southwest extension of the Ramal 4 vein. We plan to execute 22,000 meter of diamond drilling in 2022.

Tambomayo. In 2020, we executed 3,946 meter of diamond drilling at the near-mine project “Los Diques”, with encouraging results at the 4,500 level. In order to continue the exploration within the mine, we are currently excavating a 600-meter exploration tunnel at the 4540-mine level, which we expect to be complete during the fourth quarter of 2022.

82

Additionally, a second exploration tunnel will be executed the second quarter of 2022 to explore the eastern extension of the Mirtha vein in the Venturosa sector.

Finally, during 2022, the Soledad and Diques Norte near-mine project will be explored. We expect to execute 5,500 meters of diamond drilling.

Uchucchacua. In September 2021, Buenaventura announced the temporary suspension of mining and ore processing activities at the Uchucchacua mine, including the underground exploration activities.

For 2022, the short-term exploration program includes the Nora-Geraldine and Karen-Rosalia targets and the mid-long term exploration program includes the exploration of Cahipampa Norte, Nevada and Huantajalla Este. We plan to execute two additional drilling projects at this site: first, a 32,600-meter diamond drilling project and, second, an additional 47,400-meter drilling project.

Competition

We believe that competition in the metals market is based primarily upon cost. One of Buenaventura’s competitive advantages is that it has a diversified portfolio in terms of commodities (which include gold, silver, copper, zinc and lead) and in a number of assets (with 10 mining operations located in different regions of Peru). Additionally, Buenaventura’s long term business plan relies on three main drivers of value: its portfolio of operations, its portfolio of projects (seeking organic growth with a disciplined capital allocation) and, finally, Buenaventura’s position as a ‘partner of choice’ for several other companies in the mining sector in Peru. We also compete with other mining companies and private individuals for the acquisition of mining concessions and leases in Peru and for the recruitment and retention of qualified employees.

Sales of Metal Concentrates

All of our metal production is sold to smelters and traders, either in concentrate or metal form, such as gold-silver concentrate, silver-lead concentrate, zinc concentrate, lead-gold-copper concentrate, gold-copper concentrate and gold and silver bullion. Our concentrates sales are made under one to three-year, U.S. Dollar-denominated contracts, pursuant to which the selling price is based on world metal prices as follows: generally, in the case of gold and silver-based concentrates, the London Spot settlement prices for gold, less certain allowances, and the London Spot or the U.S. Commodities Exchange settlement price for silver, less certain allowances; and, in the case of base-metal concentrates, such as zinc, lead and copper, the London Metals Exchange (“LME”) settlement prices for the specific metal, less certain allowances. Sales of concentrates and metal allow for price adjustments based on their market price at the end of the relevant quotational period (QP), generally being the month of, the month before, or the month following the scheduled month of shipment or delivery according to the terms of the contracts. Sales of concentrates and metals at provisional prices include a gain (loss) to be received at the end of the QP, based on the spread between the actual price at the end of the QP and the agreed contractual average prices; this is considered a variable portion of the consideration. Changes in the price during the QP are recognized in the “Sales of goods” caption of the consolidated statements of profit or loss.

The historical average annual prices for gold and silver per ounce and our average annual gold and silver prices per ounce for each of the last two years and through March 31, 2022 are set forth below:

	Gold		Silver
	Average Annual	Our Average Annual	Average Annual	Our Average
	Market Price	Price(1)	Market Price	Annual Price(1)
	US$/oz.(2)	US$/oz.	US$/oz.(3)	US$/oz.
2020	1,769.6	1,842	20.5	22.14
2021	1,798.9	1,775.4	25.14	25.09
2022 (through March 31, 2022)	1,877.2	1,895.8	24.01	24.1

(1) Our average annual price includes only the consolidated average annual price from our mines.

(2) Average annual gold prices are based on the London PM fix as provided by Metals Week.

83

(3) Average annual silver prices are based on London Spot prices. Most of the sales contracts we enter into with our customers state a specific amount of metal or concentrate the customer will purchase. We have sales commitments from various parties for nearly all of our estimated 2022 production; however, concentrates not sold under any of our contracts may be sold on a spot sale basis to merchants and consumers.

(1) Represents committed sales volumes from 2022 to 2024.

We also sell refined gold, which is derived from our operations at Orcopampa, Tambomayo, Coimolache and La Zanja to Asahi Refining, or “Asahi,” which further refines the gold. During 2021, the price of gold supplied was determined based on, for the gold content, the quotation for gold at the London Gold Market PM fixing in U.S. Dollars, and for the silver content, the quotation for silver at the London Silver Market spot fixing in U.S. Dollars or at spot prices, minus, in each case, certain minimum charges, as well as charges for customs clearance and treatment of the gold (which varies depending on its gold and silver content). We may elect to have our material toll refined at Asahi’s works and returned to our account for sale to third parties. Pursuant to our agreement, we are responsible for delivering the gold to Asahi’s designated flight at the Lima airport.

Hedging/Normal Sales Contracts

We and our wholly owned subsidiaries are completely unhedged as to the prices at which our gold and silver will be sold. See “Item 3. Key Information—D. Risk Factors—Factors Relating to the Company—Our financial performance is highly dependent on the prices of gold, silver, copper and other metals.”

El Brocal uses derivative instruments to manage its exposure to changes in the price of metals. Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

El Brocal’s hedge is classified as a cash flow hedge. The effective portion of gain or loss on the hedging instrument is initially recognized in the consolidated statements of changes in equity, under the caption other equity reserves, while the ineffective portion is recognized immediately in the consolidated statements of profit or loss in the finance costs caption. Cerro Verde has not engaged in, and is currently not engaged in, gold or copper price hedging activities, such as forward sales or option contracts, to minimize their respective exposures to fluctuations in the price of gold and copper.

From January to December 2021, El Brocal had outstanding hedging commitments amounting to 23,750 fines tons of copper at an average fixed price of US$ 7,193 per ton.

From January to December 2021, El Brocal had outstanding hedging commitments amounting to 1,000 fines tons of copper at an average fixed price of US$ 3,850 per ton.

Regulatory Framework

Mining and Processing Concessions

In Peru, as in many other countries, surface land is owned by private landowners, while the government retains ownership of all subsurface land and mineral resources. Our right to explore, exploit, extract, process and/or produce silver, gold and other metals is granted by the Peruvian government in the form of mining and processing concessions. The rights and obligations of holders of mining concessions, provisional permits and processing concessions and other similar matters are currently set forth in the General Mining Law (Single Unified Text approved by Supreme Decree 014-92-EM), which is administered by MEM.

Pursuant to the General Mining Law, filers of mining claims must obtain a mining concession before they start any mining activity. Depending on the applicable regime, applications for mining concessions must be filed with the regional mining directors of each regional government where the mining concession is located (artisan and small-scale miners); or with Instituto Geológico Minero y Metalúrgico the Geological, Mining and Metallurgical Institute of Peru INGEMMET (general regime).

Mining concessions are irrevocable, provided the holder of a mining concession complies with the obligations set forth in the General Mining Law and applicable regulations. Such concessions have an indefinite term, subject to payment of an annual concession fee per hectare granted and achievement of minimum annual production for each hectare, or payment of a penalty when applicable. Failure to achieve annual production targets will result in a penalty. Failure to pay annual concession fees or fines for two consecutive years in any mining concession will result in the cancellation of such mining concession. Failure to satisfy minimum annual production thresholds for a specified period of time (currently thirty years beginning the year after the mining concessions were granted for mining concessions granted after October 10, 2008, and thirty years beginning on January 1, 2009 for mining concessions granted before October 10, 2008) could result in cancellation of the mining concessions.

Our processing concessions enjoy the same duration and tenure as our mining concessions, subject to payment of a fee based on nominal capacity of the applicable processing plant. Failure to pay processing fees for two consecutive years will result in the cancellation of the processing concessions.

Our mining rights and processing concessions are in full force and effect under applicable Peruvian laws. We believe we are in compliance with all material terms and requirements applicable to the mining rights and processing concessions and that we are not subject to any condition, occurrence or event that would cause the revocation, cancellation, lapse, expiration or termination thereof, except that we may, from time to time, allow to lapse, revoke, cancel or terminate mining rights and processing concessions that are not material to the conduct of our business.

In addition to obtaining mining rights from the Peruvian government, applicable Peruvian regulations require us to obtain easements or other rights from private landowners that own the surface land above the mineral resources that we intend to explore or mine. Supreme Decree No. 042-2017-EM requires us to obtain such easements or other rights before commencing exploration activities. We have been actively seeking to acquire land surface rights, easements for land containing prospective geological exploration target sites, deposits that can be exploited in the future and areas suitable for plants or facility sites. Regarding processing concessions, Article 82 of Supreme Decree Nº 020-2020-EM, Regulation for Mining Proceedings, in force and effect since August 9, 2020, requires holders of such concessions to own the land underlying the concession or to have the authorization of the owner of the land. We have been actively seeking to acquire land surface deposits that can be exploited in the future and areas suitable as plant or facility sites.

The possibility of developing mining activities in an urban area or urban expansion area is linked to the compatibility of such areas and mining activities. The Law Regulating Mining Concessions in Urban Areas and Urban Expansion Areas and related regulations set forth procedures for the granting of mining rights in urban and urban expansion areas. To grant a mining concession in an urban area and an urban expansion area, MEM is required to receive the approval of the council of the applicable provincial municipality. The council has sixty days to issue its decision. Mining concessions in urban expansion areas are granted for 10-year terms, which may be renewed by MEM subject to the approval of municipal authorities, but cannot exceed 100 hectares.

Law No. 28964, which became effective on January 25, 2007, created the Organismo Supervisor de la Inversión en Energía y Minería (OSINERGMIN) as the government agency in charge of regulating and auditing the electricity, hydrocarbon and mining activities of companies. Law No. 28964 provides that the overview and audit of activities related to the environment, mining safety and health regulations may be performed by companies duly certified and approved by OSINERGMIN. However, pursuant to Supreme Decree No. 001-2010-MINAM, OSINERGMIN transferred its environmental supervisory functions to the Environmental Evaluation and Oversight Agency (OEFA). Beginning July 22, 2010, OEFA assumed the authority to carry out unexpected audits and levy fines on companies if they fail to comply with enforceable environmental regulations and approved environmental assessments. According to Supreme Decree No. 128-2013-PCM, mining companies are required to make monetary contributions to OSINERGMIN and, according to Supreme Decree No. 130-2013-PCM, monetary contributions are also required to be made to OEFA.

Regarding employee health and safety and employer liability in mining activities, Law 28964 has been amended and replaced by Law 29783. Such employee health and safety and employer liability and related matters are now audited by the Ministry of Labor and Employment (MINTRA). Law 29783, as amended by Law 30222, establishes the minimum rules designed to prevent employee safety risks and allocate liabilities in relation to such risks. The main principle of this law is that the employer assumes the economic, legal and any other type of liability arising from accidents or diseases suffered by the employee while working and guarantees the employee’s health and safety in connection with the employee’s work. This legislation entitles labor inspectors to inspect commercial facilities and, under certain circumstances, suspend operations. By Supreme Decree No. 003-2013—TR, MINTRA transferred its security supervisory, audit and sanctioning functions to the National Superintendence of Labour Inspection (SUNAFIL). Such law amended the relevant provision of the criminal code, which currently establishes that a person who intentionally breaches the safety and health provisions, and who after being required by the relevant authority, does not adopt the measures contemplated in such provisions, is deemed to jeopardize the life, health or physical integrity of such person’s employees and may be held criminally liable for such behavior.

On July 28, 2016, Supreme Decree No. 024-2016-EM, as amended by Supreme Decree No. 029-2016-EM and Supreme Decree No. 023-2017-EM, relating to Occupational Health and Safety Regulations for Mining was published. These Regulations aim to prevent the occurrence of incidents, work-related accidents and occupational diseases, aiming to promote a culture of prevention of occupational hazards in mining activities. MEM through the General Directorate of Mining, is the competent authority on Occupational Health and Safety policy and regulation. In addition, SUNAFIL is the competent authority for the supervision and enforcement of compliance with legal and technical standards related to Occupational Safety and Health in Mining; while OSINERGMIN is the competent authority to supervise compliance of the legal and technical provisions related to the safety of infrastructure in mining.

COVID-19 Pandemic

In response to the COVID-19 pandemic, the Peruvian government issued Supreme Decree N° 044-2020-PCM, as amended, declaring a state of national emergency and halting social mobility. As of March 16, 2020, mining activities were initially permitted, however, only critical operations were allowed, which did not include exploration, exploitation, processing and mining transportation.

Supreme Decree N° 080-2020-PCM, which modified Supreme Decree N° 044-2020-PCM on May 3, 2020, allowed the gradual resumption of economic activities, including large-scale mining. Nevertheless, recovery was not automatic because the companies were obligated to file a monitoring plan with the relevant governmental authority (e.g., the Ministry of Energy and Mines). Relevant governmental authority approval was required to register these monitoring plans on the Ministry of Health web portal, SICOVID.

The “Health Protocol for the implementation of prevention and response measures against COVID-19 in the activities of the Mining Subsector, the Hydrocarbons Subsector and the Electricity Subsector,” approved by Ministerial Resolution N° 128-2020-MINEM/DM, determined the structure of the monitoring plan that shall be prepared and submitted by mining companies and their workers and/or contractors that work or provide services in all activities of the mining subsector.

On June 4, 2020, Supreme Decree N° 101-2020-PCM, allowed companies to conduct exploration and exploitation activities, including processing, transportation, storage and mines closure regarding large, middle and small mining.

87

To address environmental matters during the COVID-19 pandemic, the government issued Urgency Decree N° 026-2020 and Urgency Decree N° 029-2020, suspending deadlines for administrative and judicial procedures with government entities. This decree was extended through June 10, 2020. Legislative Decree N° 1500, issued on May 11, 2020, outlined companies’ compliance with environmental obligations during the pandemic. It allowed companies including those in the mining sector to suspend environmental obligations. Such disposition of obligations was later included in R.C.D. 008-2020-OEFA/CD, issued by OEFA, the environmental enforcement agency that regulates environmental obligations and supervises compliance during the pandemic.

According to such regulations, supervision of environmental obligations is linked to the monitoring plan registered by companies on SICOVID. We and our associated companies are in compliance with all COVID-19-related regulations when conducting mining activities.

The term of the state of national emergency imposed by the government through Supreme Decree N° 044-2020-PCM was extended several times and finally ended on November 30, 2020. However, a new state of national emergency was imposed by the government on November 30, 2020 through Supreme Decree N° 184-2020-PCM, starting on December 1, 2020. Under this new decree and its extensions, all mining activities are allowed.

In this regard, by means of Supreme Decree N° 007-2021-EM, published on April 1, 2021, the Ministry of Energy and Mines issued a special measure related to the environmental management instruments of the mining sector. These regulations establish the reprogramming of mining activities and their respective environmental measures, commitments and obligations assumed in the approved Environmental Impact Assessments, Complementary Environmental Management Instruments and their modifications, up to a maximum period of twelve (12) months, counted from the presentation of the reprogramming plan before the competent environmental authority, without implying the modification, reduction and/or incorporation of environmental measures, commitments and/or obligations assumed in the aforementioned studies and instruments, in response to the State of National Emergency for the impact of COVID-19 and the health emergency. The measure is applicable for those activities that could not have been developed due to the impact of the pandemic.

Environmental Matters

In 2005, Peru enacted the General Environmental Law (Law No. 28611), which establishes the main environmental guidelines and principles applicable in Peru. Pursuant to the General Environmental Law, the Ministry of Environment (MINAM) issued national environmental regulations, which have gradually replaced prior guidelines governing governmental agencies environmental competencies. OEFA, as the environmental enforcement agency, has the authority to inspect mining operations and fine companies that fail to comply with prescribed environmental regulations and their approved environmental assessments.

In May 1993, the regulation for environmental protection under mining and metallurgical activities (reglamento para la proteccion ambiental en la actividad minero - metalúrgica), was published and approved by Supreme Decree No. 016-93-EM. This regulation required every mining unit that began operations before May 1993 to file a Preliminary Environmental Assessment (“EVAP”) followed by a Program for Environmental Adequacy and Management (“PAMA”). Additionally, an EIA had to be submitted for any new operations. In 2014, this regulation was repealed by Supreme Decree No. 040-2014-EM  (reglamento de Protección y Gestión Ambiental para las Actividades de Explotación, Beneficio, Labor General, Transporte y Almacenamiento Minero), approved on November 12, 2014, which regulates mining production, processing, labor, transportation and storage and sets forth a new set of requirements for these activities. Going forward, social and technical teams from MEM will gather the baseline information to regulate these activities. Early involvement by the regulatory authority in environmental assessments processes is expected to shorten approval times. On March 2, 2020 this regulation was modified by Supreme Decree N° 005-2020-EM (Modificación del Reglamento de Protección y Gestión Ambiental para las Actividades de Explotación, Beneficio, Labor General, Transporte y Almacenamiento Minero), amending articles 76, 102 and 132. Pursuant to these modifications the ITS would permit the reserve confirmations through underground works, communicate ITS approval to the social influence area and direct the storage of concentrate minerals in warehouses out of mining concessions. This modification also created Article 133A which introduces the possibility of excuting certain changes and improvements without modifying the EIA, though only with a Prior Communication (Comunicación Previa). During September 2021, MINAM published and approved by Supreme Decree N° 027-2021, directing that the Servicio Nacional de Meteorología e Hidrología (the “SENAMHI”), have the exclusive authority and jurisdiction to evaluate and review all air pollution models required from mining sector participants during the review of environmental impact assessments.

88

In 1996, MEM also issued regulations that establish maximum permissible levels (“LMPs”) of (i) liquid effluents emissions and (ii) elements and compounds present in gaseous emissions resulting from mining activities. Mines and processing plants that were in operation before May 1993 were required to comply with LMPs within 10 years and in the meantime, operators were required to prepare Environmental Adaptation and Management Programs, or PAMAs, that set forth plans to ensure compliance with more stringent LMPs. The first General Water Law was enacted in 1969. In 2008 and 2010, MINAM enacted new water quality standards and new LMPs for liquid effluents, and, in 2009, all Peruvian mining companies were required to submit updated environmental management plans that complied with water quality standards and new LMPs for liquid effluents to MEM. By the end of 2015, Supreme Decree No. 015-2015 - MINAM (the “2015 Decree”) was enacted, modifying water quality standards for designated beneficial uses which apply to mining companies and establishing supplementary provisions related to compliance. In 2017, Environmental Quality Standards (Estándares de Calidad Ambiental) (ECAs) for water were modified by Supreme Decree No. 004-2017-MINAM. Permissible maximum limits approved in 2010 are still valid.

In May 2008, the MINAM was created by Legislative Decree No. 1013. MINAM’s main functions include formulating and implementing policies and regulations related to environmental matters and pollution control, including regulation of air and water quality standards, through supervision and education.

On March 26, 2013, Supreme Decree No. 002-2013-MINAM regarding soil quality became effective. It approved the ECAs for soils, or “Standards,” which are applicable to any project or activity that may generate an environmental impact. Subsequently, on March 25, 2014, supplementary provisions for the application of the standards were approved through Supreme Decree No. 002-2014-MINAM. Projects operating at the time those regulations came into force were required to submit the first phase of soil characterization within twelve months of the passage of the decree. Buenaventura and its associated companies submitted this information within the required time.

In 2017, new ECAs for soils were approved by Supreme Decree No. 011-2017-MINAM, replacing the ECAs approved by Supreme Decree No. 002-2013-MINAM. The new ECAs are applicable to new environmental assessments that are required to carry out future mining activity in accordance with the mining regulations. With respect to the environmental assessments that were approved prior to the approval of the new ECAs, Supreme Decree No. 002-2013-MINAM will remain applicable and the new ECAs will only be enforced when the approved environmental assessments need to be modified or updated. In 2017, Supreme Decree No. 012-2017-MINAM replaced Supreme Decree No. 002-2014-MINAM, approving new supplementary provisions for application of the new ECAs. Buenaventura and its associated companies have taken into consideration all new environmental regulations when executing its mining activities.

In 2012, Peru enacted Supreme Decree No. 020-2012-EM, which added Chapter XVII to the Mining Proceedings Regulations approved by Supreme Decree No. 018-92-EM. The new provisions require the approval of the General Mining Directorate of MEM or of the relevant regional government before proceeding to start and re-start exploration, development, preparation and exploitation. The authorizations to start and re-start mining activities may need to be pre-approved by MEM if the mining activities affect indigenous or native people.

In addition, in December 2017, a new regulation for Solid Waste Management was approved by Supreme Decree No. 014-2017-MINAM which brought into force the new Law for Integral Management of Solid Waste, approved by Legislative Decree No. 1278 in December 2016. This resulted in new regulations for all extractive productions and services in Peru, including mining, which prioritize the material and energy recovery of solid waste through different methods, including recycling, reuse and co-generation.

89

Regulations governing mining explorations. In May 2008, the Peruvian government enacted Supreme Decree 020-2008-EM, which governs mining exploration activities and related matters. At the end of 2017, this Supreme Decree was modified by a new regulation for exploration activities. Under Supreme Decree 042-2017-EM, exploration activities fall into two categories: Category I and Category II. Category I exploration activities are those involving no more than 40 drilling platforms or affecting a surrounding area measuring less than 10 hectares in size, while Category II exploration activities are those involving between 40 and 700 drilling platforms and affecting an area measuring greater than 10 hectares. For Category I exploration activities, an Environmental Impact Statement (Declaración de Impacto Ambiental) (DIA) is required. For Category II exploration activities, a semi-detailed EIA (EIAsd) that incorporates technical, environmental and social matters is required. In addition, the new regulation approved by Supreme Decree No. 042-2017-EM requires an Environmental Technical Report (Ficha Técnica Ambiental) (FTA), which is a complementary environmental assessment for exploration activities that do not have significant negative impacts. Exploration activities must start within twelve months following the date that the DIA or EIAsd is approved. The DIA, the EIAsd and the FTA, as applicable, must be approved before exploration activities begin. Any commitments assumed by mining companies in a DIA, EIAsd or FTA are mandatory and, if they are not fulfilled, OEFA has the authority to fine non-compliant mining companies. The regulation also provides that the holder of mining concessions will perform specified closure and post closure activities during exploration programs. In addition, fines can be imposed if exploration programs begin before the DIA, the EIAsd and the FTA are approved, and the approval of environmental assessments for exploration activities performed within protected natural areas requires the approval of the competent authority. Exploration in Prehispanic Archeological Sites (referred to in Supreme Decree No 004-2000-ED) is forbidden unless expressly authorized by the Ministry of Culture.

In May 2008, MEM also enacted Supreme Decree No 028-2008-EM, which regulates the citizen participation process within the framework of environmental permit approval. The DIA and EIAsd provide local communities with an opportunity to engage actively in this process.

The regulation for exploration activities Supreme Decree No. 042-2017-EM, was modified by Supreme Decree No. 019-2020 - EM. The most important changes are: the Ministry de Energy and Mines allows the positive administrative silence for FTA, additional assumptions for Prior Communication, the determination of a deadline to OEFA which must conduct the final closure inspection and the rules modifications of Citizen Participation for the FTA.

The following DIAs and sdDIAs were approved in 2021:

Regulations Promoting Investments. Supreme Decree 054-2013-PCM was passed to promote investment projects. It allows companies to submit a supporting technical report, ITS (Informe Técnico Sustentatorio), to modify ancillary components, capacity expansions, or introduce technological improvements in exploration and exploitation activities. SENACE (EIAd) and MEM (DIA and EIAsd) will then issue a compliance waiver within no more than 15 working days from the date of submission. This should facilitate the approval of environmental assessments for our new exploration projects and simplify the issuance of certificates of non-existence of archeological remains required for mining projects.

On December 28, 2015, the Servicio Nacional de Certificación Ambiental (SENACE), which operates under the auspices of MINAM, took responsibility for the assessment and approval of detailed EIA (EIAd) submitted by private, public, or mixed-capital organizations. This development is consistent with the expansion of MINAM’s technical and regulatory capacities. In 2020, EIAs for Yumpaq and Trapiche were prepared under SENACE supervision.

90

Moreover, the Environmental Baseline Elaboration Guidelines (Guía para la elaboración de la Línea Base en el marco del Sistema Nacional de Evaluación del Impacto Ambiental– SEIA) and the Identification and Characterization of Environmental Impacts Guidelines (Guía para la Identificación y Caracterización de Impactos) were approved by Ministerial Resolution No. 036-2018-MINAM in 2018. The purpose of the aforementioned guidelines is to provide information, directives and references to professionals involved in the review of baselines, as well as to provide general guidelines to the project owner or consulting firm for the process of identifying and evaluating the impacts on the environment (including physical, biological and social impacts), the results of which allow decisions to be made on the environmental viability of the project.

Finally, in 2021, Supreme Decree No. 026-2021-EM modified the Supreme Decree No. 040-2014-EM, giving companies the option to carry out actions not incorporated in their Environmental Impact Statements, when the purpose that action was to control the effects of environmental emergencies. Companies must communicate the execution of these actions to the OEFA within 10 days of execution.

In 2021 the following IGAs related to EIAd were approved:

Finally, the Environmental Baseline Elaboration Guidelines (Guía para la elaboración de la Línea Base en el marco del Sistema Nacional de Evaluación del Impacto Ambiental– SEIA) and the Identification and Characterization of Environmental Impacts Guidelines (Guía para la Identificación y Caracterización de Impactos) were approved by Ministerial Resolution No. 036-2018-MINAM in 2018.

Regulations governing mine closures. In 2003, Law No. 28090, Ley que Regula el Cierre de Minas (Law that Regulates the Closing of Mines), established the obligations and procedures that mining companies must follow to prepare, submit and execute plans for the closing of mines, or “Closure Plans,” and the granting of financial environmental guarantees to secure compliance with Closure Plans. We are required to submit a Closure Plan for new projects to MEM within one year following approval of an EIA or PAMA; and inform MEM semi-annually of any progress on the conditions established in the Closure Plan. We are also required to perform the Closure Plan consistent with the schedule approved by MEM during the life of the project and to set up a financial environmental guarantee that covers the estimated amount of the Closure Plan. In addition, Supreme Decree No. 020-2008-EM requires mining companies that perform exploration activities to conduct certain closing activities in accordance with the approved environmental assessment, subject to deferral under certain circumstances, and contemplates a Closure Plan to be submitted by the mining company following the terms and conditions of Supreme Decree Nº 033-2005-EM. Supreme Decree Nº 036-2016-EM modified articles 12 and 17 and included articles 46-A y 66-A of the Supreme Decree Nº 033-2005-EM.

In August 2021, the MEM enacted Law No. 31347 regulating the closure of mines. This law makes important changes in the obligations of mine owners regarding the financial guarantees required in their Mine Closure Plans. The law requires that Mine Closure Plans guarantee the progressive closure for the main facilities (Componentes Principales) and also requires that Mine Closure Plan guarantees must cover the costs of environmental rehabilitation ordered by OEFA. Finally, the law also regulates the actions and obligations of the authorities in case of abandonment of mining facilities.

In 2017, our Closure Plans were approved by MEM for all of our mines and advanced explorations activities.

On November 9, 2009 Supreme Decree No. 078-2009-EM became effective, creating additional environmental obligations for mining concessions holders. Under this provision, mining concessions holders that performed mining activities, including mining exploration, production and processing activities or related activities, without having an environmental certification are required to prepare and perform an environmental remediation plan to address the environmental impact in the areas in which such activities have been conducted. Environmental remediation plans can only be filed once mining activities have ceased and contain a detailed description of all mining facilities and activities performed without the corresponding environmental certification, including maps and related information, a detailed description of the environmental impacts created by such activities, a detailed description of the remediation actions, a detailed description of the compensation that is proposed to be made, a budget and schedule of the remediation activities, including their costs, and a bond in favor of MEM for the cost of the execution of the measures contained in the environmental remediation plan. Once the environmental remediation plan is completed, mining concessions holders are required to inform the auditing entity so it can verify that the actions were carried out as approved. The auditing entity is required to send the respective report to the relevant authority so that the bond may be returned.

Law No. 28271, Law that Regulates the Environmental Liabilities of Mining Activities (Ley que Regula los Pasivos Ambientales de la Actividad Minera), came into force on July 7, 2004 and serves to regulate the identification of environmental liabilities and financial responsibility for remediation in mining activities, in each case to mitigate any negative impact mining may have with respect to the health of the population, environment and property. Pursuant to Law No. 28271, as amended by Law No. 28526 and Legislative Decree No. 1042, MEM’s technical branch will identify environmental liabilities, mining companies responsible for abandoned mining facilities, mining works and residue deposits that may be linked to such environmental liabilities and holders of inactive mining concessions with mining liabilities. Holders of inactive mining concessions with environmental mining liabilities will be required to submit a Closure Plan and enter into environmental remediation agreements with MEM to perform any studies and work necessary to control and mitigate the risk and effects of any contamination. Regulations under Law No. 28271, Regulations of Environmental Liabilities of Mining Activities (Reglamento de Pasivos Ambientales de la Actividad Minera), were approved by Supreme Decree No. 059-2005-EM. and then modified by Supreme Decree No. 003-2009-EM.

We have presented Closure Plans to MEM for all our mining concessions with environmental mining liabilities. To date, the Hualchocopa, Lircay, Bella Unión-Paucaray, Chaquelle Ayacucho and Rifle Rumimaqui mining units have all been closed and post-closure activities at each of these units are currently underway.

We anticipate additional laws and regulations relating to environmental matters will be enacted over time. The development of more stringent environmental regulations in Peru could impose additional constraints and additional costs on our operations that would require us to make significant additional capital expenditures in the future. Although we believe that we are substantially in compliance with all known and applicable environmental regulations, there is no assurance that future legislation or regulatory developments will not have an adverse effect on our business or results of operations.

Prior Consultation with Local Indigenous Communities

In 2011, Peru enacted Law No. 29785, the Law of Prior Consultation for Indigenous and Native Communities (Ley del Derecho a la Consulta Previa a los Pueblos Indígenas y Originarios – ILO 169 Convention). This law establishes a prior consultation procedure that the Peruvian government must undertake in concert with local indigenous communities whose collective rights may be directly affected by new legislative or administrative measures. Under this law, the Peruvian governmental agency responsible for issuing or approving the administrative measure or decree in question, rather than the affected local indigenous community, retains the right to approve or reject the relevant legislative or administrative matter following such consultation. However, to the extent that any of our future projects require the promulgation of legislative or administrative measures that impact collective rights of local indigenous communities, the required prior consultation procedure may result in delays, additional expenses or failure to obtain approval for such new project.

Regulations under Law No. 29785 were approved by Supreme Decree No. 001-2012-MC, which became effective on April 2, 2012. These regulations specify the form and circumstances of the required consultation and the manner in which agreements will be formalized, and provide for a consultation process that lasts no more than 120 calendar days. In 2019, Ministerial Resolution No. 304-2019-MINEM/DM was issued, establishing the administrative procedures from the Mining Sector that require prior consultation-in case those procedures affect indigenous communities - which are: (i) processing concession; (ii) authorization to initiate or re-initiate exploration, development or exploitation activities; (iii) mineral transport; and (iv) mining labor.

At the start of the COVID-19 pandemic in 2020, the Peruvian Central Government did not make adequate accommodations and legal modifications for the use of digital tools which, consequently, interrupted the prior consultation process. However, the Peruvian Central Government made efforts to include additional mechanisms for some procedures with established COVID-19 protocols. Additionally, the process has been delayed by local indigenous communities’ involvement of political leaders to communicate the desire for and expectation of increased benefits for their respective communities. However, despite the adverse conditions, prior consultation processes in San Gabriel, Yumpag and Ccelloccasa were fulfilled and accomplished by the Peruvian Central Government in their expected stages.

Mine/Project	Type of Study	Administrative Measure
Yumpag Phase 03	2nd EIA Modification	Start of activities
San Gabriel	EIA – Detailed	Mining plan and operational permits
Ccelloccassa	EIA – First Stage	Start of activities

Permits

We believe that our mines and facilities have all necessary material permits to operate. All future exploration projects will require a variety of permits. Although we believe the permits for these projects can be obtained in a timely fashion, permitting procedures are complex, time-consuming, and subject to potential regulatory delay. We cannot predict whether we will be able to renew our existing permits or whether material changes in existing permitting conditions will be imposed. Non-renewal of existing permits or the imposition of additional permitting conditions could have a material adverse effect on our financial condition or results of operations. Moreover, the COVID-19 pandemic slowed down the permitting process all through the mine lifecycle, and further delays are to be expected.

Insurance

We maintain a comprehensive insurance program designed to address specific risks associated with our operations, in addition to covering the insured risks common to major mining companies. Our insurance program is provided through the local Peruvian insurance market and includes employers’ liability, comprehensive third-party general liability and comprehensive automobile liability, all risk property on a replacement basis, including transit risks, as well as business interruption insurance and mining equipment insurance.

93

Mining Royalties and Taxes

Under Peruvian law, holders of mining concessions are required to pay the Peruvian government a mining royalty (regalia minera) for the exploitation of metallic and non-metallic resources. In accordance with Law No. 28258, as amended by Law No. 29788, mining royalties are payable either as a specified percentage of operating profit or 1% of revenues, whichever is higher. If the mining royalty is calculated as a percentage of operating profit, marginal rates ranging from 1% to 12% that increase progressively for companies with higher operating margins will apply. Percentages for the distribution of proceeds from mining royalties were amended by Law No. 28323.

Mining companies that are a party to mining stabilization agreements are not required to pay a mining royalty during the tenure of their stabilization agreements.

In addition to mining royalties, pursuant to Law No. 29789, effective from October 1, 2011, mining operations in Peru are subject to an extraordinary mining tax. Mining companies that do not have taxation stability agreements with the Peruvian government, such as Buenaventura, will pay the “Special Mining Tax” (Impuesto Especial a la Minería). The Special Mining Tax is calculated each quarter as a percentage of operating profit. Marginal rates ranging from 2% to 8.4% that increase progressively for companies with higher operating margins will apply. Mining companies that have stability agreements with the Peruvian government will pay the “Special Mining Duty” (Gravamen Especial a la Minería) created by Law No. 29790. The Special Mining Duty is calculated as a percentage of operating profit, with marginal rates ranging from 4% to 13.12% that increase progressively for companies with higher operating margins.

Safety

During 2021, neither Buenaventura nor any of its subsidiaries have reported any fatal accidents in our mining units and projects. In addition, as of December 2021, we have gone 29 months without a fatal accident in mining activities. However, three fatal accidents were reported in non-mining activities at the Conenhua, Canal Huaruro and Almacén Campoy locations, respectively.

Starting in 2017, we expanded classifications parameters to account for lost time due to injuries and external non-mining projects (public roads, health and education facilities construction) all of which were reported to the Bureau of Labor.

At Buenaventura, we believe that safety is an inherent part of every process, rather than something separate. This means that Safety management is the responsibility of the operational officer in charge of each respective process. Safety is part of our quality indicators and a crosscutting value throughout the Company.

In light of these results, we must continue to work hard and allocate resources to ensure sustainability through a Critical Risk management approach (operational controls) and the Pact for Life (change in beliefs).

94

The table below shows Accident Rates based on the number of fatal and lost time accidents (Frequency) and days lost (Severity). The table shows an increasing trend for Accident Rates between 2020 (0.16) and 2021 (2.52).

Our main activities included the following:

● Outreach to labor unions through awareness aessions called“Internalizing commitments to life thinking about the family that awaits us at home.”

● Strengthening Buenaventura’s personnel and contractors through the activities of the personal commitment program named “Pacto por la Vida”: http:www.pactoporlavida.com

● Implementation of the “Critical Risk Management” initiative, focused on the prevention of permanent disabling and fatal accidents through Engineering-type controls.

● Involvement of the supervision levels, workers and unions through the Participatory Safety approach.

● Improved efficiency of corrective actions through the prioritization of engineering-type operating controls and the application of the ICAM methodology for accident investigation.

We keep on working towards the achievement of a Safe Production Culture that involves the entire personnel of Buenaventura.

ITEM 4A.Unresolved Staff Comments

None.

ITEM 5.Operating and Financial Review and Prospects

In this Item 5, we present information first with respect to Buenaventura, followed by information with respect to Yanacocha, in which, as of December 31, 2019, 2020 and 2021 we had a 43.65% equity participation for all years. On February 8, 2022, the Company sold the entirety of its stake in Yanacocha to Newmont. As such, Yanacocha has been classified on our financial statements as an asset held for sale as outlined in Note 1(e) to our Consolidated Financial Statements.

We record our investments in Yanacocha and Cerro Verde in accordance with the equity method as further described in “Item 5. Operating and Financial Review and Prospects—Buenaventura—A. Operating Results—General” and Note 2.4(f) to the Consolidated Financial Statements.

BUENAVENTURA

Introduction

The following discussion should be read in conjunction with the Consolidated Financial Statements as of December 31, 2020 and 2021 and for the years ended December 31, 2019, 2020 and 2021 and the related Notes thereto included elsewhere in this Annual Report, and  Item 5 to our annual report for the year ended December 31, 2020 (the “2020 20-F”). The Consolidated Financial Statements are prepared and presented in accordance with IFRS as issued by the IASB. We present our consolidated financial statements in U.S. Dollars.

A.Operating Results

General

Overview. We were established in 1953 and are one of Peru’s leading producers of gold, silver and other metals. Our Consolidated Financial Statements comprise all of our accounts and those of our subsidiaries, which include:

● the Julcani, Tambomayo, Uchucchacua and Orcopampa mining units;

● the Colquijirca and La Zanja mines, which are owned by our non-wholly owned consolidated subsidiaries;

● Condesa, which is mainly a holding company for internal investments in affiliated mining companies;

● Conenhua, which is mainly engaged in the transmission of electric power to mining companies;

● other minor subsidiaries; and

● discontinued operations.

We also have material equity investments in (i) Yanacocha, which is an equity investee engaged in the exploitation and commercialization of gold, (ii) Cerro Verde, which is an equity investee engaged in the exploitation and commercialization of copper and (iii) Coimolache, which is an equity investee engaged in the exploitation and commercialization of gold and silver. We account for these investments under the equity method.

98

Yanacocha. Historically, a substantial part of our net profit (loss) before income tax was derived from our equity interest in Yanacocha. The Company’s equity participation, as of December 31, 2019, 2020 and 2021 in Yanacocha was 43.65%. During December 2021, the Company’s management decided to dispose of its investment in Yanacocha. On February 8, 2022, the Company sold the entirety of its stake in Yanacocha to Newmont for consideration of US$300,000,000, as well as contingent payments linked to (i) the production of the Sulphides Project that Newmont plans to develop at Yanacocha and (ii) potential future increases in mineral prices. Collectively, such contingent payments can potentially amount to an additional US$100,000,000. As such, Yanacocha has been classified on our financial statements as an asset held for sale as outlined in Note 1(e) to our Consolidated Financial Statements.

Cerro Verde. As of December 31, 2021, we had a 19.58% equity participation in Cerro Verde, which allows us to exercise significant influence over the company. As a result, we account for our investment in Cerro Verde using the equity method. Although Cerro Verde has no fixed dividend policy, there is an understanding that earnings not required for capital expenditures or future development projects are expected to be distributed.

Results of operations. The primary factors affecting our results of operations are:

● the amount of gold, silver, zinc and copper produced and sold;

● prevailing world market prices for gold, silver, zinc and copper;

● commercial terms with respect to the sale of ore concentrates; and

● our operating expenses.

Gold and silver price hedging. Our revenues and earnings are strongly influenced by world market prices for gold, silver, zinc and copper that fluctuate widely and over which we have no control. Depending upon the metal markets and other conditions, we may from time to time hedge our gold and silver sales to decrease our exposure to fluctuations in the prices of these metals. We and our wholly owned subsidiaries are currently completely unhedged as to the price at which our gold and silver will be sold. As a result, we are fully exposed to the effects of changes in prevailing market prices of gold and silver.

Operating costs and expenses. Operating costs and expenses consist of:

● operating costs, which are direct production costs, the major component of operating expenses;

● exploration costs in operational mining sites;

● depreciation and amortization expenses;

● exploration costs in non-operational mining areas;

● administrative expenses, which principally consist of personnel expenses;

● royalties, which consist of payments to third parties and the Peruvian government to operate leased mining rights; and

● selling expenses, which principally consist of freight expenses.

99

Reserves. We utilize geological mapping, projection of ore-bearing structures, diamond drilling, core logging and chemical assaying, in addition to drifting along previously indicated mineralization, to replace and grow reserves. In addition, we use metallurgical test-work of core and bulk samples as a follow-up activity to prove the amenability of any previously indicated mineralization to certain extraction methods available on site. We continuously analyze this information with respect to tonnage, precious-metals average grades, metallurgical recoveries and economic value and allocate funds preferentially to those projects that have the best potential to sustain or enhance profitable mine production in the near-term. Our mining operations are primarily conducted underground and consist of deposits that are difficult to explore and measure in advance of mining and in which the value or prospects for ore based on geologic evidence exceeds the value based on proved reserves throughout most of the life of mines supported by them, or extramensurate deposits.

In addition, underground mine infrastructure, such as declines, shafts and/or dewatering/ore haulage crosscuts, that facilitate access to ore reserves are constructed and categorized as mine development. We consider such underground mine infrastructure vital to assure sustainable mine production and reserve production. The design, construction and implementation of our underground mine infrastructure are presented and supervised by our operations manager with the Board of Directors’ (the “Board”) approval. We capitalize mine development and mineral land costs incurred after we have approved the feasibility of the conceptual study of a project. Upon commencement of production, we amortize these costs over the expected life of the mining area, based on proven and probable reserves and other factors.

Our other mining operations are smaller and have variable fluctuations in production and reserves due to complexities of the ore located in certain mining operations (such as the Colquijirca mine); the sale of certain mining operations; partial and temporary closures of mining operations; and the production of silver only as by-product of gold (such as the Orcopampa mine).

Net income and net distributable income. Under Peruvian law, each company is required to establish a legal reserve equal to at least 20% of its paid-in capital on an unconsolidated basis. An annual contribution of at least 10% of net income must be made until such legal reserve equals 20% of paid-in capital. The legal reserve may offset losses or be capitalized. However, following any instance in which the reserve is used, Peruvian law calls for mandatory replenishment of the reserve.

Royalties. Royalty expenses consist mainly of payments made by us pursuant to lease agreements relating to mining rights for the Orcopampa mine. Specifically, we pay the lessor a royalty of 10% of the value of the concentrates produced. We are also required to pay the Peruvian government mining royalties and taxes. In addition to mining royalties, pursuant to Law No. 29789, effective October 1, 2011, mining operations in Peru are subject to an extraordinary mining tax. See “Item 4. Information on the Company—Buenaventura—B. Business Overview—Regulatory Framework—Mining Royalties and Taxes.”

Environmental protection laws and related regulations. Our business is subject to Peruvian laws and regulations relating to the exploration and mining of mineral properties, as well as the possible effects of such activities on the environment. We conduct our operations substantially in accordance with such laws and regulations.

Discontinued operations. During 2020, we sold our Mallay mining unit previously classified as discontinued during 2019. During December 2021, Buenaventura management reclassified its negative investment held in Minera Yanacocha S.R.L for US$264,838,000 as available for sale and recognized it as a discontinued operation in the consolidated income statement for the years 2019, 2020 and 2021. See Note 1(e) and Note 2.4(w) to the Consolidated Financial Statements. On February 7, 2022, Buenaventura entered into definitive agreements to sell the entirety of its interest in Yanacocha for cash consideration of $300,000,000 to Newmont, as well as contingent cash payment linked to (i) production of the Sulphides Project that Newmont plans to develop at Yanacocha and (ii) potential future increases in mineral prices. Collectively, such contingent payments can potentially amount to an additional $100,000,000. As a result of this transaction, Yanacocha has been classified as an asset held for sale. As of December 31, 2021 the mining units with discontinued operations were Yanacocha, Mallay, Poracota and Shila-Paula.

SUNAT litigation. Buenaventura is involved in legal proceedings against SUNAT in connection with SUNAT’s refusal to recognize Buenaventura’s deductions with respect to contracts for physical deliveries and certain contractual payments made by the Company during the years 2007 and 2008, as well as tax loss, which was offset in 2009 and 2010.

100

During 2007 and 2008, Buenaventura modified its gold client contracts, shifting from a fixed price arrangement to a variable price arrangement which allowed the Company to appropriately benefit from improved market prices. This change incurred significant expenses for Buenaventura during the 2007-2008 two-year transition period, which also impacted the income tax payable by Buenaventura for said fiscal years. However, the modified pricing structure also favorably impacted Buenaventura’s financial results with a corresponding increase in Buenaventura’s income tax payment to SUNAT.

SUNAT’s position is that Buenaventura should disregard the additional expenses incurred in connection with the shift to variable price arrangement for purposes of calculating its income tax for fiscal years 2007 and 2008. According to SUNAT, said payments correspond to an early settlement of financial derivative contracts in situations where the Company did not establish the purpose or risks covered by such instruments. Additionally, SUNAT does not recognize the tax losses that the Company offset during fiscal years 2009 and 2010, related to the losses incurred during fiscal years 2007 and 2008.

The claim for the years 2007, 2008, 2009 and 2010 initially amounted to S/373.3 million soles (approximately US$103.7 million) which, according to SUNAT’s estimations, amounted to 2,107.5 million soles (approximately US$585.4 million) including penalties and accrued interest as of the date of commencement of the collection proceedings.

On November 26, 2020, following the intervening tax court’s decision to dismiss the Company’s appeal against certain Administrative Resolutions issued by SUNAT in connection with the above-referenced matter, SUNAT began collection proceedings in respect of such amounts. Following the commencement of such collection proceedings by SUNAT, the Company filed a request for deferral and payment plan of the amounts claimed by SUNAT in order to make such tax payments over a 67-month term, in addition to making interest payments in connection with such payments. The requested payment plan consisted of an initial payment in an amount equal to 14% of the amount claimed by SUNAT and 66 equal installments for the remaining amounts. In order to finalize the deferral and payment agreement with SUNAT, the Company was required to deliver Letters of Credit (as described below under “—Issuance of letters of credit and default under our Syndicated Term Loan”) in an amount equal to the aggregate claimed amount in accordance with applicable law. To satisfy this requirement, on December 30, 2020, the Company entered into the Syndicated L/C Agreement with a group of financial entities, as described below and following delivery of the Letters of Credit, SUNAT approved the Company’s payment plan.

On July 30, 2021, the Company paid the full amount of the tax debt related to the 2007, 2008, 2009 and 2010 tax processes that were subject to deferment and installment and that are recorded in the caption “Trade and other receivables, net”. For the fiscal years 2007 and 2008, the total amount paid of S/1,584,227,000 (equivalent to US$398,548,000), which includes the updating of interest as of July 30, 2021 for S/78,279,000 (equivalent to US$19,693,000). For the fiscal year 2009, the total amount paid was S/193,398,000 (equivalent to US$48,654,000) which includes an update to reflect interest owed as of July 30, 2021 of S/8,477,000 (equivalent to US$2,133,000). For the fiscal year 2010, which was subject to deferral and installment, the total amount paid was S/356,691,000 (equivalent to US$89,733,000) which includes the updating of interest as of July 30, 2021 of S/16,762,000 (equivalent to US$4,217,000).

As of December 31, 2021, as a result of the advance payment mentioned above, the deferral and installment resolutions of the SUNAT tax liability have been rendered null and the letters of credit that were delivered as collateral for said debt have been returned to the issuing banks.

Critical Accounting Policies and Estimates

The following is a discussion of our application of critical accounting policies that require our management, or “Management,” to make certain assumptions about matters that are highly uncertain at the time the accounting estimate is made, and where different estimates that Management reasonably could have used in the current period, or changes in the accounting estimate that are reasonably likely to occur from period to period, would have a material impact on our Consolidated Financial Statements. Management has identified the following key accounting estimates:

● determination of mineral reserves and resources;

● unit-of-production depreciation;

● closure of mining units provision;

101

● inventories;

● impairment of non-financial assets;

● deferred income tax and recoverability; and

● fair value of contingent consideration.

The Company’s key judgments associated with its accounting policies include:

● contingencies and uncertain tax treatment;

● development start date;

● production start date;

● useful life of property, plant and equipment; and

● revenue from contracts with customers.

We also have certain accounting policies that we consider important, such as our policies for investments carried at fair value, and exploration costs that do not meet the definition of critical accounting estimates, as they do not require Management to make estimates or judgments that are subjective or highly uncertain.

Management has discussed the development and selection of our critical accounting estimates with the Audit Committee of the Board.

Determination of mineral reserves and resources

Recoverable proven and probable reserves and resources are the part of a mineral deposit than can be economically and legally extracted or produced at the time of the reserve and resources determination. The determination of reserves involves numerous uncertainties with respect to the ultimate geology of the ore bodies, including quantities, grades and recovery rates. Estimating the quantity and grade of reserves and resources requires Buenaventura to determine the size, shape and depth of its ore bodies by analyzing geological data, such as sampling of drill holes, tunnels and other underground workings. In addition to the geology of Buenaventura’s mines, assumptions are required to determine the economic feasibility of mining these reserves, including estimates of future commodity prices and demand, the mining methods Buenaventura used and the related cost incurred to develop and mine its reserves and resources. The process to estimate proven and probable ore reserves and resources is audited by an independent consultant each year.

All estimated reserves and resources represent estimated quantities of mineral proven and probable that under current conditions can be economically and legally processed. Changes could occur on reserve and resources estimates due to, among others, revisions to the data or geological assumptions, changes in prices, production costs and results of exploration activities. Changes in estimated reserves and resources primarily would impact the depreciation of development costs, property, plant and equipment related directly to mining activity, the provision for mine closure, the assessment of the deferred asset’s recoverability and the amortization period for development costs.

Unit-of-production depreciation

Reserves and resources are used in determining the depreciation and amortization of mine-specific assets. This results in a depreciation or amortization charge proportional to the depletion of the anticipated remaining life of mine (LOM) production. Each mine’s life is assessed annually to evaluate: (i) physical life limitations and (ii) present assessments of economically recoverable reserves of the mine property. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes are recorded prospectively.

102

This results in a depreciation or amortization charge that is proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, is determined based on both its physical life limitations and present assessments of economically recoverable reserves of the mine property where the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes in estimates are accounted for prospectively.

Closure of mining units provision

We record a provision for mine closure when a legally enforceable obligation arises, which is independent of the full depletion of the mine reserves. Once such an obligation has been appropriately measured, it is recorded by creating a liability equal to the amount of the obligation and recording a corresponding increase to the carrying amount of the related long-lived asset (mine development cost and property, plant and equipment). Over time, the amount of the obligation changes, impacting recording and accretion expenses. Additionally, the capitalized cost is depreciated and/or amortized based on the useful lives of the related assets.

Any difference in the settlement of the liability is recorded in the results of the period in which such settlement occurs. The changes in the fair value of an obligation or the useful life of the related assets that occur from the revision of the initial estimates should be recorded as an increase or decrease in the book value of each of the obligation and related asset.

Following our accounting treatment, as of December 31, 2021, we have recorded an accrual for mine closure costs of US$272.0 million to comply with governmental requirements for environmental remediation for Buenaventura and its mining subsidiaries. Please see Note 15(b) to the Consolidated Financial Statements.

We assess our provision for closure of mining units annually. This assessment entails significant estimates and assumptions because there are a number of factors that will affect the ultimate liability for this obligation. These factors include estimating the scope and costs of closing activities, technological changes, regulatory changes, increases in costs compared to inflation rates and changes in the discount rates. Such estimates or assumptions may result in actual expenses in the future that differ from the amounts provisioned at the time the provisions were established. The provision at the date of this report represents our best estimate of the present value of future costs for the closure of mining units.

Inventories

Inventories are classified as short-term or long-term depending on the length of time that management estimates will be needed to reach the production state of concentrate extraction for each mining unit.

Net realizable value tests are performed at least annually and represent the estimated future sales price of the product based on prevailing spot metals prices at the reporting date, less estimated costs to complete production and bring the product to sale. Additionally, management also considers the time value of money in calculating the net realizable value of our long-term inventories.

Classified minerals, which are materials with metal content that were removed from the pit of the Colquijirca mining unit for treatment at the expansion operation plant, contain lower grade ore than the average of treated minerals and are available to continue in the process of recovery of mineral and concentrates. Because it is generally impracticable to determine the mineral contained in the classified mineral located in the deposit field near Tajo Norte by physical count, reasonable estimation methods are employed. The quantity of minerals delivered to classified mineral is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper, lead and zinc grades of material delivered to classified minerals.

For minerals outside leach platform inventories, finished and in-progress goods are measured by estimating the number of tons added and removed. The number of contained gold ounces is based on assay data, and the estimated recovery percentage is based on the expected processing method. Tonnages and ounces of mineral are verified by periodic surveys.

For minerals inside leach platform inventories, reasonable estimation methods are employed because it is generally impracticable to determine the mineral contained in leach platforms by physical count. The quantity of material delivered to leach platforms is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated ore grades of material delivered to leach platforms.

103

Impairment of non-financial assets

We determine whether the operations of each mining unit are cash generating units, considering each mining unit operation independently. We assess at each reporting date whether there is an indication that an asset may be impaired. If any such indication exists, we estimate the asset’s recoverable amount. An asset’s recoverable amount is (i) the fair value less costs of disposal and (ii) value in use and is determined for an individual asset (cash-generating unit) unless the asset does not generate cash inflows that are clearly independent of those from other assets or groups of assets. These assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates, operating costs and others. These estimates and assumptions are subject to risk and uncertainty.

A cash-generating unit is the smallest identifiable group of assets that generates cash inflows from continuing use that are independent of the cash inflow generated by other assets or groups of assets. We have determined the operations of each mining unit as a single cash generating unit.

In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate that reflects current market assessments of the time value of money and the risks specific to the asset.

At each reporting date, we update our assessment of the recoverability of the book value of our long-term assets under the procedures established by IAS 36 – “Impairment of Assets” for all of our mining units. As a result, we recorded impairment losses and reversals of impairment during 2019, 2020 and 2021.

In 2019, we recorded an impairment for US$2.1 million as a result of the analysis of the recoverable amount of our Julcani mining unit. The main factors considered in the impairment analysis were reserves and life of the mine.

In 2020, we recorded a reversal in our impairment provision related to our Julcani mining unit of US$2.1 million. This provision was previously recorded in 2019.

In 2021, we recorded an impairment in our Río Seco unit for US$19.9 million. In addition, we recognized a reversal of impairment provision of US$5.0 million for our La Zanja mining unit.

These impairment charges have not had an impact on our operating cash flows. Cash flows used to assess recoverability of our long-lived assets and measure the carrying value of our mining operations were derived from current business plans using near-term price forecasts reflective of the current environment and Management’s projections for long-term average metal prices and operating costs.

Our asset impairment evaluations required us to make several assumptions in the discounted cash flow valuation of (i) our individual mining operations, including near and long-term metal price assumptions, production volumes, estimates of commodity-based and other input costs and (ii) proven and probable reserve estimates, including any costs to develop the reserves and the timing of producing the reserves, as well as the appropriate discount rate. Our December 31, 2019, 2020 and 2021 impairment evaluations were based on price assumptions reflecting prevailing metals prices for the following years.

We believe events that could result in additional impairment of our long-lived assets include, but are not limited to, (i) decreases in future metal prices, (ii) decreases in estimated recoverable proven and probable reserves and (iii) any event that might otherwise have a material effect on mine site production levels or costs.

Deferred income tax asset and recoverability

In preparing our annual Consolidated Financial Statements, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the tax and book bases of assets and liabilities. Deferred income tax assets and liabilities are measured using tax rates applicable to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates and laws is recognized in income in the period in which such changes are enacted.

104

All deductible temporary differences and loss carry-forwards generate the recognition of deferred assets to the extent that it is probable that they can be used in calculating taxable income in future years. Deferred income tax liability is recognized for all deductible temporary differences and tax loss carry-forwards, to the extent that it is probable that taxable profit will be available against which the deductible temporary differences and unused tax losses can be utilized. The carrying amount of the deferred income tax asset is reviewed at each consolidated statement of financial position date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred asset to be utilized. Unrecognized deferred assets are reassessed at each consolidated statement of financial position date.

Deferred assets and liabilities are offset if there is a legal right to set them off and the taxes deferred relate to the same entity and the same tax authority.

Deferred tax assets, including those resulting from unused tax losses, require that we assess the likelihood that we would generate taxable earnings in future periods to apply the deferred tax assets. Estimated future taxable income is based on projections of cash flow from operations and application of the tax law existing in each jurisdiction. To the extent to which actual future cash flows and taxable income differ significantly from those estimated, our ability to realize the deferred tax assets posted as of the reporting date may be affected.

In addition, future changes in the tax law in jurisdictions where we operate could limit our ability to obtain tax deductions in future periods.

Our unrecognized deferred income tax asset related to the investment in associates was US$64.8 million as of December 31, 2021 (US$64.2 million as of December 31, 2020).

Fair Value of contingent consideration

The contingent consideration arising from a business combination is measured at fair value at the date of acquisition, as part of the business combination. If the contingent consideration is eligible to be recognized as a financial liability the fair value is subsequently re-measured at each date of the Consolidated Financial Statements. Determining the fair value of the contingent consideration is based on a model of discounted future cash flows. The key assumptions take into account the likelihood of achieving each goal of financial performance as well as the discount factor.

Contingencies and uncertain tax treatment

Contingent liabilities, when identified, are assessed as either remote, possible or probable. Contingent liabilities are recorded in the consolidated financial statements when it is probable that future events will confirm them and when their amount can be reasonably estimated. Contingent liabilities deemed as possible are only disclosed, together with a possible debit range, when determinable, in notes to the Consolidated Financial Statements.

Contingent assets are not recognized in the Consolidated Financial Statements; however, they may be disclosed in notes to the Consolidated Financial Statements if it is probable that such contingent assets will be realized. See Note 31(c) and (d) to the Consolidated Financial Statements.

Determining contingencies inherently involves the exercise of judgment and calculation of the estimated outcomes of future events.

Development start date

We assess the status of each exploration project of our mining units to determine when the development phase begins. One of the criteria used to evaluate the development start date is when we determine that the property can be economically developed.

105

Production start date

We assess the stage of each mine under development to determine when a mine moves into the production stage. The criteria used to assess the start date are determined based on the nature of each mining project, the complexity of a plant and its location. We consider various relevant criteria for assessing when the mine is substantially complete and ready for its planned use. Some of these criteria are the level of capital expenditure compared to development cost estimates, a reasonable testing period for the mine’s plant and equipment and the ability to produce ongoing production of metal.

When a mine development project moves into the production stage, the capitalization of certain costs ceases, and they are considered as inventory or expenses, except for costs that qualify for capitalization relating to mining asset additions or improvements, underground mine development or mineable reserve development. It is also at this point that depreciation or amortization commences.

Useful life of property, plant and equipment

Straight-line method

Depreciation is calculated under the straight-line method of accounting considering the lower of estimated useful lives of the asset or estimated reserves of the mining unit. The useful lives are the following:

Property, Plant and Equipment	Estimated Years of Useful Life
Buildings, constructions and other	2 to 11
Machinery and equipment	5 to 10
Transportation units	5
Furniture and fixtures	5 to 10
Computer equipment	3 to 4

An item of property, plant and equipment is de-recognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising from de-recognizing an asset (calculated as the difference between the proceeds from the sale and the book value of the asset) is included in the consolidated statement of profit or loss in the year the asset is de-recognized.

Revenues from contracts with customers

According to our accounting policies, revenue is recognized when control of goods or services is transferred to the customer in an amount equal to the consideration that we expect to receive in exchange for those goods and services.

Revenues from sales of concentrates and metals are recognized at the point in the time when control of the asset is transferred to the customer. Revenues related to services, such as energy generation and transmission, industrial services, and other services, are recognized over time.

See Note 2.4(q) to the Consolidated Financial Statements.

Results of Operations for the Years Ended December 31, 2021 and 2020

Sales of goods. Sales of goods increased by 35%, mainly due to the net effect of an increase in both volume (mainly explained by the production reduction related to the State of National Emergency due to the COVID-19 pandemic during 2020) and variations in the average realized prices, as set forth in the chart below:

	Year ended December 31,
Sales of goods	2020	2021	Variation	Variation
	(US$ in thousands)
Copper (a)	181,311	340,522	159,211	88	%
Silver (b)	230,498	316,930	86,432	37	%
Gold (c)	229,590	262,676	33,086	14	%
Zinc (d)	120,546	143,580	23,034	19	%
Lead	48,426	51,907	3,481	7	%
Manganese sulfate	4,051	4,976	925	23	%
	814,422	1,120,591	306,169	38	%
Commercial deductions (e)	(179,748)	(196,201)	(16,453)	9	%
Hedge operations (f)	(6,464)	(51,952)	(45,488)	704	%
Fair value of accounts receivable	5,154	(3,831)	(8,985)	N.A.
Adjustments to prior period liquidations	4,255	(5,137)	(9,382)	N.A.
Total sales of goods	637,619	863,470	225,851	35	%

(a) Copper sales. The increase in copper sales is mainly due to increases of 24% in the volume of copper sales of the Colquijirca mining unit, and a 51% increase in the average realized price.

(b) Silver sales. The increase in silver sales is mainly due to the net effect of: (i) increases of 86% and 57% in the volume of silver sales in the Colquijirca and Julcani mining units, respectively, partially offset by a decrease of 24% in the Uchucchacua mining unit, and (ii) an increase in the average realized silver price of 13%.

(c) Gold Sales. The increase in gold sales is mainly due to increases of 20% and 63% in the volume of gold sales in the Orcopampa and Colquijirca mining units, respectively, partially offset by a decrease in the average realized price of 4%.

(d) Zinc sales. The increase in zinc sales is mainly due to the net effect of a 42% increase in the average realized price and a 34% decrease in the volume of zinc sold in the Colquijirca mining unit.

(e) Commercial deductions. The increase in 9% in the commercial deduction is mainly explained by the increase in sales. Sales of goods figures are obtained by deducting the commercial deductions which corresponds to adjustments in price for treatment and refining charges. These charges can include certain penalties that, in accordance with the applicable contract, are deducted from the international fine metal spot price and that are incurred after the time of sale of the applicable concentrate.

(f) Hedge operations. Sales of goods figures are obtained by considering the effect of the hedge operations related to sales.

The following tables reflect the average realized prices and volumes of gold, silver, lead, zinc and copper sold during the years ended December 31, 2020 and 2021, as well as the variation in such average realized prices and volumes recorded for these years:

Average Realized Price	Year ended December 31,
	2020	2021	Variation
Gold (US$/oz.)	1,841.96	1,775.37	(4)	%
Silver (US$/oz.)	22.14	25.09	13	%
Lead (US$/t)	1,708.25	2,290.74	34	%
Zinc (US$/t)	2,233.55	3,182.05	42	%
Copper (US$/t)	6,259.49	9,455.09	51	%

107

Volume Sold	Year ended December 31,
	2020	2021	Variation
Gold (oz.)	124,644	147,956	19	%
Silver (oz.)	10,410,476	12,631,890	21	%
Lead (t)	28,348	22,659	(20)	%
Zinc (t)	53,971	45,122	(16)	%
Copper (t)	28,966	36,015	24	%

Sales of services. Sales of services during 2021 were in line with 2020 as set forth in the chart below:

Sales by services	Year ended December 31,
	2020	2021	Variation	Variation
	(US$in thousands)
Insurance brokerage	14,753	15,651	898	6	%
Energy generation and transmission	5,532	5,401	(131)	(2)	%
Total sales of services	20,285	21,052	767	4	%

Royalty income. In 2021, royalty income received by our subsidiary Chaupiloma amounted to US$15.9 million, representing a decrease of 15% from the US$18.6 million in royalty income received in 2020. This decrease was mainly explained by a decrease in the sales of Yanacocha.

Total operating costs. Total operating costs in 2021 increased by 25% compared to 2020 as indicated in the following table:

Operating Costs	Year ended December 31,
	2020	2021	Variation	Variation
	(US$ in thousands)
Cost of sales of goods, excluding depreciation and amortization (a)	(393,888)	(529,731)	(135,843)	34	%
Unabsorbed cost due to production stoppage (b)	(27,758)	(25,509)	2,249	(8)	%
Cost of sales of services, excluding depreciation and amortization	(1,554)	(1,269)	285	(18)	%
Depreciation and amortization	(189,620)	(187,211)	2,409	(1)	%
Exploration in operating units (c)	(28,044)	(56,412)	(28,368)	101	%
Mining royalties	(11,749)	(12,974)	(1,225)	10	%
Total operating costs	(652,613)	(813,106)	(160,493)	25	%

(a) Cost of sales of goods, excluding depreciation and amortization. The increase in cost of sales of goods was mainly due to increase in our Colquijirca, Orcopampa and Tambomayo mining units in US$77.8 million, US$19.0 million, and US$18.4 million, respectively.

	2020	2021	Variation	Variation
	(US$in thousands)
Colquijirca	170,148	248,021	77,873	46	%
Uchucchacua	100,097	95,359	(4,738)	(5)	%
Tambomayo	64,107	82,531	18,424	29	%
Orcopampa	37,139	56,183	19,044	51	%
La Zanja	31,978	46,531	14,553	46	%
Julcani	16,679	31,319	14,640	88	%

The increase in cost of sales across Buenaventura’s mining unit during 2021 is explained by the production reduction in 2020 related to the State of National Emergency due to the COVID-19 pandemic, which paralyzed operations from March 16, 2020 until the second quarter of 2020.

108

(b) Unabsorbed cost due to production stoppage. The allocation of fixed production overheads to the costs of conversion is based on the normal capacity of the production facilities under IAS 2, Inventories and unabsorbed overheads are recognized as an expense in the period in which they are incurred. Cost of sales related to the unabsorbed costs are presented separately from the rest of cost of sales.

During the year 2021, the unabsorbed production costs of the mining units corresponded to the stoppage of production of the Uchucchacua mining unit incurred as of October 2021. The production stoppage was due to operational problems in the unit that were aggravated by the COVID-19 pandemic. During 2020, the unabsorbed production costs of the mining units corresponded to the stoppage of the Group’s production as a result of the State of National Emergency related to the COVID-19 pandemic. Due to these factors, Buenaventura’s mining units have operated below planned volume.

(c) Exploration in operating units. The increase in exploration in operating units was mainly due to increases in our Colquijirca, Orcopampa, and Uchucchacua mining units in US$11.3 million, US$6.3 million, and US$4.4 million, respectively. The increase in exploration activities during 2021 compared to 2020 is explained by a lower exploration activity during 2020 as a result of the effects of COVID-19 pandemic.

Total operating expenses. Operating expenses in 2021 increased compared with those of 2020 due to changes in the following components:

Operating Expenses, net	Year ended December 31,
	2020	2021	Variation	Variation
	(US$ in thousands)
Administrative expenses	(67,185)	(67,585)	(400)	1	%
Selling expenses	(18,533)	(20,827)	(2,294)	12	%
Exploration in non-operating areas	(8,475)	(11,270)	(2,795)	33	%
Write –off of stripping activity asset (a)	(11,633)	(6,763)	4,870	(42)	%
Impairment loss (reversal) of long-lived assets (b)	2,083	(14,910)	N.A.	N.A.
Reversal for contingences	(4,150)	(2,687)	1,463	(35)	%
Other, net (c)	2,690	(29,260)	N.A.	N.A.
Total operating expenses, net	(105,203)	(153,302)	(48,099)	46	%

(a) Write-off of stripping activity asset. During 2021, as a result of the reserves review, the subsidiary El Brocal wrote off the phase 6 for a total of 1,181,280 DMT at a value of US$6,763,000. The write-off corresponds to a new estimation of reserves of the superficial operation as a result of the topographical information. During 2020, as a result of the review of the mineral reserve balances, El Brocal wrote off the phase 9 for a total of 1,102,117 DMT at a value of US$11,633,000. The write-off corresponds to a loss of reserves due to variation in technical and economic parameters such as: decrease in estimated prices; increased cut-off; percentage decrease in payable items; and new block model.

(b) Impairment reversal / loss of long-lived assets. During 2021, the Group identified impairment indicators in Orcopampa, Uchucchacua, La Zanja and Río Seco. The Group evaluated and concluded that there is impairment in Río Seco unit of US$19.9 million. In addition, La Zanja mining unit recognized a reversal of impairment of US$5.0 million. During 2020, Buenaventura recognized a reversal for impairment of long-lived assets for US$2.1 million derived from the evaluation of its Julcani mining unit.

(c) Other, net. The variation from an income of US$2.7 million in 2020 to an expense of US$29.3 million in 2021 is primarily due to the net effect of:

- an income of US$2.4 million during 2021 compared to US$4.4 million during 2020 related to insurance claim recovery of the subsidiary El Brocal.

- an income of US$3.3 million during 2021 related to dividends in other investments. During 2020 no dividends incomes were received.

109

- an income of US$3.8 million occurred in 2020 related to revenue from commercial claims. During 2021 no revenues from commercial claims were recorded.

- higher provision for impairment of spare parts and supplies of US$5.1 compared to 2020. During 2021 the provision of impairment of spare parts and supplies amounted to US$22.4 million, compared to US$17.3 million in 2020.

- higher changes in environmental liabilities provision of US$15.4 million mainly explained by the update of the closure plan for environmental liabilities of Santa Bárbara and Delta Ulpamayo of the subsidiary El Brocal of US$12.7 million.

Other income (expense) captions. Other income (expenses) captions in 2021 increased compared with those of 2020 due to changes in the following components:

Other income (expense) captions	Year ended December 31,
	2020	2021	Variation	Variation
	(US$ in thousands)
Shares in the results of associates and joint venture (a)	62,702	240,450	177,748	283	%
Finance income	2,411	5,952	3,541	147	%
Finance costs (b)	(37,822)	(60,629)	(22,807)	60	%
Net (loss) from currency exchange difference (c)	(4,116)	(18,686)	(14,570)	354	%

(a) Shares in the results of associates and joint ventures. Shares in the results of associates and joint venture increased by US$177.7 million during 2021 compared to 2020 primarily explained by an increase of US$179.6 million in our share of Sociedad Minera Cerro Verde S.A.A. See “Item 5. Operating and Financial Review and Prospects—Cerro Verde” for more information

(b) Finance costs. Finance costs increased by US$22.8 million during 2021 compared to 2020. The increase was primarily explained by the net effect of:

- higher interest expenses of US$13.3 million related to the bonds issued during 2021;

- higher finance expenses of US$12.1 million related to commissions for bond letters issued to SUNAT;

- higher amortized cost of financial obligations of US$8.8 million;

- lower interest expenses related to financial obligations of US$6.0 million; and -lower expense of US$5.7 million related to the change of the fair value related to contingent consideration liability (during 2021, the change of fair value resulted in a finance income).

(c) Net (loss) from currency exchange difference. Changes in the exchange difference expense of US$14.6 million are explained by the fluctuations in exchange due to a year on year weakening of the PEN relative to the U.S. dollar (3.624 PEN/USD as of December 31, 2020 compared to 3.998 PEN/USD as of December 31, 2021). SUNAT’s claim is based in Peruvian Soles as part of Buenaventura’s “accounts receivables”, therefore, a higher exchange rate decreases the total amount when converted to U. S. dollars.

Income tax from continuing operations. Provisions for income tax changed from an expense of US$25.4 million in 2020 to an income of US$23.7 million in 2021, mainly due to the deferred income tax that changed from an expense of US$15.5 million in 2020 to a benefit of US$44.0 million in 2021. The changed is mainly explained by a higher deferred asset related to tax-loss carryforward due to a higher tax-loss during 2021 of US$28.4 million and a higher deferred asset related to provision for closure of mining units of US$16.1 million due to a higher provision during 2021.

Non-controlling interest income (loss). Non-controlling interest income changed from an income of US$1.3 million in 2021 compared to a loss of US$14.6 million in 2020 primarily explained by the changes in the results of the subsidiary El Brocal from an expense of US$12.9 million in 2020 compared to income of US$4.3 million as a result of our share in net profit in El Brocal.

	(14,621)	1,271	15,892	(109)	%

Income (loss) for the year. As a result of the foregoing, net loss increased by US$112.5 million in 2021 compared to 2020. Loss for the year was 22% of revenues in 2020 and 29% of revenues in 2021.

Discontinued operations. Buenaventura management reclassified its negative investment held in Minera Yanacocha S.R.L for US$264,838,000 as available for sale and recognized it as a discontinued operation in the consolidated statements of profit (loss) for the years 2019, 2020 and 2021. See Note 1(e) and Note 2.4(w) to the Consolidated Financial Statements. On February 7, 2022, Buenaventura entered into definitive agreements to sell the entirety of its interest in Yanacocha for cash consideration of $300,000,000 to Newmont, as well as contingent cash payment linked to (i) production of the Sulphides Project that Newmont plans to develop at Yanacocha and (ii) potential future increases in mineral prices. Collectively, such contingent payments can potentially amount to an additional $100,000,000. As a result of this transaction, Yanacocha has been classified as an asset held for sale. As of December 31, 2021, the mining units with discontinued operations were Yanacocha, Mallay, Poracota and Shila-Paula.

Income tax from discontinued operations. For 2021, the change is mainly explained by a deferred asset related to provision for sale of investment in associate Yanacocha of US$50.4 million and deferred liability related to effect of translation into U.S. dollars for that asset of US$9.0 million.

Results of Operations for the Years Ended December 31, 2021 and 2020 by Segment

We present the operating results for each of our operating segments for the years ended December 31, 2020 and 2021 in more detail in Note 33 to the Consolidated Financial Statements.

The change in sales of goods for the year ended December 31, 2021 as compared to the year ended December 31, 2020 is mainly explained by the changes in volume sold, as presented in the following chart:

Sales of goods – Mining Segments	Year ended December 31,
	2020	2021	Variation	Variation
	(US$ in thousands)
Julcani (a)	32,034	56,065	24,031	75	%
Orcopampa (b)	77,825	89,567	11,742	15	%
Uchucchacua (c)	90,420	79,375	(11,045)	(12)	%

Colquijirca (e)	255,275	410,390	155,115	61	%

(a) Julcani. Sales of goods increased by 75% in 2021 compared to 2020 due to the effect of a 14% increase in the average realized silver price and a 57% increase in the quantity of silver sold at that unit.

(b) Orcopampa. Sales of goods increased by 15% in 2021 compared to 2020 due to the net effect of a 20% increase in the quantity of gold sold at that unit partially offset by a 4% decrease in the average realized gold price.

(c) Uchucchacua. Sales of goods decreased by 12% in 2021 compared to 2020 due to the net effect of a 17% increase in the average realized price and a 24% decrease in the quantity of silver sold at that unit as a consequence of the operation suspension in that unit.

(d) Tambomayo. Sales of goods increased by 27% in 2021 compared to 2020 due to the net effect of a 4% decrease and 10% increase in the average realized gold and silver prices, respectively and an increase of 10% and 8% in the quantity of gold and silver sold, respectively at that unit.

(e) Colquijirca. Sales of goods increased by 61% in 2021 compared to 2020 due to a 51% increase in the average realized copper price and a 24% increase in the quantity of copper sold at that unit.

Total operating expenses – Mining Segments. The change in operating expenses for the year ended December 31, 2021 as compared to the year ended December 31, 2020 is mainly explained by:

Operating Expenses – Mining Segments	Year ended December 31,
	2020	2021	Variation	Variation
	(US$ in thousands)
Julcani	(2,050)	(5,741)	(3,691)	180	%
Orcopampa	(10,628)	(8,481)	2,147	(20)	%
Uchucchacua (a)	(10,169)	(19,717)	(9,548)	94	%
Tambomayo (b)	(19,776)	(25,639)	(5,863)	30	%
La Zanja	(7,846)	(4,907)	2,939	(37)	%
Colquijirca (c)	(24,923)	(38,248)	(13,325)	53	%

(a) Uchucchacua. The higher operating expense of US$9.5 million was mainly due to personnel expenses and expenses of US$5.8 million related to the operation suspension in 2021.

112

(b) Tambomayo. The higher operating expense of US$ 5.9 million was mainly due to a higher write-off of assets in that unit for US$ 1.8 million.

(c) Colquijirca. The higher operating expense of US$13.2 million wasmainly due to a US$12.8 million expense as a result of an update of the closure plan for environmental liabilities of Santa Bárbara and Delta Ulpamayo.

Total operating expenses - Other Segments

Operating income (expenses) – Other Segments	Year ended December 31,
	2020	2021	Variation	Variation

Rental of mining concessions	(49)	(193)	(144)	294	%

(a) Industrial activities segment. The higher expense of US$20.4 million in 2021 compared to 2020 was mainly explained by a US$19.9 million impairment loss recorded by our subsidiary Río Seco which suspended operations until the restart of Uchucchacua operations (Río Seco receives raw materials from Uchucchacua mining unit).

Results of Operations for the Years Ended December 31, 2020 and 2019

B.Liquidity and Capital Resources

As of December 31, 2021 and 2020, we had cash and cash equivalents of US$377.0 million and of US$235.4 million, respectively.

113

Cash provided by operating activities for the years ended December 31, 2021 and 2020. Net cash and cash equivalents provided by operating activities changed from an income of US$142.4 million to an expense of US$197.5 million, primarily due to the changes shown in the chart below:

Operating activities cash flows	Year ended December 31,
	2020	2021	Variation	Variation
	(US$ in thousands)
Proceeds from sales (a)	708,196	945,631	237,435	34	%

Net cash and cash equivalents provided by (used in) operating activities	142,434	(197,510)	N. A.	N. A.

(a) The increase in the proceeds from sales was mainly due to higher sales and production of the Group, as described in Results of Operations for the Years Ended December 31, 2021 and 2020 by Segment.

(b) The increase in dividends received from Cerro Verde was mainly due to the US$137.1 million received during 2021.

(c) The decrease in the value-added tax and other taxes recovered is explained by the lower recoveries by the Group during 2021 as a result of a higher offsetting of our tax credit applied against local sales taxes of the Group during 2021. In 2020, Buenaventura, El Brocal, La Zanja, and Río Seco recovered US$19.2 million, US$9.2 million, US$8.2 million, US$5.8 million, respectively, compared to US$14.8 million, US$6.1 million, US$6.2 million, US$0.6 million recovered by Buenaventura, El Brocal, Río Seco and La Zanja, respectively, in 2021.

(d) The increase in payments to suppliers and third parties is mainly explained by the increase in the operations and ore production by the Group, as described in Results of Operations for the Years Ended December 31, 2021 and 2020 by Segment.

(e) The variation corresponds to different payments made during 2021 and 2020 related to claims with the Tax Administration. See the detail of payments in Note 7(c) of the Consolidated Financial Statements.

(f) The higher income tax and royalties paid to Peruvian State are mainly explained by the increase in the profits and operations of the Group, as described in Results of Operations for the Years Ended December 31, 2021 and 2020 by Segment.

(g) The decrease in the interest paid was mainly explained by the changes in the interest rates negotiated with banks.

114

Cash used in investing activities for the years ended December 31, 2021 and 2020. Net cash and cash equivalents used in investing activities increased by US$24.1 million primarily due to the changes shown in the chart below:

Investing activities cash flows	Year ended December 31,
	2020	2021	Variation	Variation	%
	(US$ in thousands)
Proceeds from sale of investments	—	3,640	3,640	100	%
Proceeds from sale of property, plant and equipment (a)	24,416	739	(23,677)	(97)	%

Net cash and cash equivalents used in investing activities	(62,224)	(86,287)	(24,063)	39	%

(a) The proceeds from sale of assets decrease in 2021 mainly due to higher proceeds in 2020 related to a sale of property, plant and equipment due to a collection of US$21.0 million related to the sales of energy transmission systems in the areas of Huancavelica, Trujillo, Cajamarca, Callalli – Ares and Lorema by Buenaventura (through its subsidiary Consorcio Energético de Huancavelica S.A.). No similar sales activity occurred during 2021.

(b) In January 2020, Buenaventura acquired 19.30 per cent of common shares on a non-diluted basis from Tinka Resources Ltd., through private placement financing, which represented 65,843,620 common shares of Tinka at a price of C$0.243 per common share, for gross proceeds to Tinka of C$16 million (equivalent to US$13.4 million).

(c) The increase in capital expenditures was mainly due to the increase in Colquijirca and Uchucchacua mining units of US$13.7 million and US$5.7 million, respectively. See “Item 4: Information on the Company—Buenaventura—A. History and Development—Capital Expenditures.”

Cash provided by (used in) financing activities for the years ended December 31, 2021 and 2020. Net cash and cash equivalents used in financing activities changed from an expense of US$54.8 million in 2020 to an income of US$425.3 million in 2021 primarily due to the changes shown in the chart below:

Short-Term Debt

We borrow, from time to time, short-term unsecured loans from local Peruvian banks to supplement our working capital needs at favorable short-term interest rates. As of December 31, 2021 and 2020, the amount outstanding under such short-term loans was US$50.0 million and US$65.8 million, respectively. In 2021, we used the proceeds of such short-term loans for general working capital purposes.

Long-Term Debt

Sociedad Minera El Brocal S.A.A. On October 29, 2019, El Brocal entered into a new financing agreement in an amount of US$161,893,850 with Banco de Crédito del Perú in order to repay a financial leaseback signed in 2015 and a medium-term financing entered into in 2017. The new financing agreement has the following terms and conditions:

	Tranche A	Tranche B
Principal	US$113,325,695	US$48,568,155
Annual interest rate	3.76 percent	Three-month LIBOR plus 2.39 percent
Term	5 years beginning in October 2019 (matures in October 2024)	7 years beginning in October 2019 (matures in October 2026)

According to this financing agreement, El Brocal is required to maintain the following financial ratios: (i) Debt service coverage ratio: Higher than 1.3, (ii) Leverage Ratio: Less than 1.0 times, and (iii) Indebtedness ratio: Less than 2.25 times. This new financial obligation is collateralized by a security agreement in respect of assets; certain contractual rights, flows and account balances, a real estate mortgage; and a mortgage on certain mining concessions.

In April and July 2020, El Brocal arranged with the Banco de Crédito del Perú to defer the payment of the second and third installment, scheduled for April 30, and July 30, 2020 (each installment in an amount of US$5,396,000 exclusively consisting of principal) through 2 new promissory notes with a maturity of 180 days. The initial due dates of these promissory notes were October 27, 2020 and January 26, 2021, respectively. On October 27, 2020, El Brocal rescheduled the payment of the first promissory note for an additional 180 days, with a new due date on April 24, 2021. As of December 31, 2021, these promissory notes were paid in full.

As of December 31, 2021 and 2020, the amount outstanding under this financing was US$118.1 million and US$139.7 million, respectively. Compliance with the financial ratios is monitored by El Brocal’s management. El Brocal’s management obtained a waiver from Banco de Crédito del Perú for any possible breach of the financial ratios that occurred for the fourth quarter of 2020. As of December 31, 2021, El Brocal complied with the coverage and indebtedness ratios.

Empresa de Generación Huanza S.A. The long-term debt of Huanza is made up of: (i) a financial lease agreement entered into on December 2, 2009, with Banco de Crédito del Perú in an aggregate amount of US$119.0 million, for purposes of constructing a hydroelectric power station. Huanza is the lessee under such agreement. On October 29, 2020, as part of Buenaventura’s strategy to preserve cash, Huanza entered into an amendment to this lease agreement (in respect of the final principal installment thereunder, amounting to US$44,191,000), pursuant to which parties agreed to extend the maturity through May 2022 and to modify the interest applicable to the loan to 30-day LIBOR plus a 2.10% margin, and (ii) a financial lease agreement entered into on June 30, 2014, with Banco de Crédito del Perú in an aggregate amount of US$103.4 million.

- Offering Format: private placement under Rule 144A and Regulation S of the U.S. Securities Act of 1933.

116

- Listing: The bonds were listed on the Singapore Exchange Securities Trading Limited (“SGX-ST”).

The bonds were offered in a private placement to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (hereinafter the “Securities Act”), and outside the United States to non-U.S. persons in accordance with Regulation S under the Securities Act. The Notes are fully and unconditionally guaranteed jointly and severally by Compañía Minera Condesa S.A., Inversiones Colquijirca S.A., Procesadora Industrial Río Seco S.A. and Consorcio Energético Huancavelica S.A.

As part of its issuance of the Notes, Buenaventura entered into an indenture (the “Indenture”) among Buenaventura, The Bank of New York Mellon, and various subsidiary guarantors. Under the terms of the Indenture, Buenaventura agreed to comply with certain restrictive covenants. As a result of these covenants, Buenaventura must confirm that it is in compliance with the Notes Indenture if it wants to undertake any transactions that involve:

(i) the incurrence of additional debt;

(ii) certain asset sales;

(iii) the making of certain investments;

(iv) the payment of dividends;

(v) the purchasing of Buenaventura’s equity interests or making any principal payment prior to any scheduled final maturity or schedule repayment of any indebtedness that is subordinated to the Notes (collectively, “Restricted Payments”, as defined in the Indenture),

(vi) creation of liens; or

(vii) a merger, consolidation or sale of substantially all assets.

These covenants are known as “Limitations on incurrence of indebtedness”, “Limitation on Asset Sales”, “Limitation on Restricted Payments”, “Limitation on Liens” and “Limitation on Merger, Consolidation or Sale of Assets”, respectively, which also have exceptions that let the Company operate in the ordinary course of business.

The following table shows our contractual obligations as of December 31, 2021:

	Payments due by Period (US$in millions)

As of December 31, 2021, we had no other commercial commitments.

Exploration Costs and Capital Expenditures

During the years ended December 31, 2021, 2020 and 2019, we spent US$11.3 million, US$8.5 million and US$11.9 million, respectively, on “exploration in non-operating areas” and US$56.4 million, US$28.0 million and US$44.2 million, respectively, on “exploration in operating units.” Our “exploration in non-operating areas” mainly focused on the Emperatriz and Marcapunta exploration projects. Our “exploration in operating units” mainly focused in the Colquijirca, Orcopampa, Uchucchacua and Tambomayo units.

117

We expect that we will meet our working capital, capital expenditure and exploration expense requirements for the next several years from internally generated funds, cash on hand and dividends received from our investments in non-consolidated mining operations. Additional financing, if necessary, for the construction of any project, is expected to be obtained from borrowings under bank loans and the issuance of debt securities. There can be no assurance, however, that sufficient funding will be available to us from the internal or external sources to finance any future capital expenditure program, or that external funding will be available to us for such purpose on terms or at prices favorable to us. A very significant decline in the prices of gold and silver would be reasonably likely to affect the availability of such sources of liquidity. In addition, if we fund future capital expenditures from internal cash flow, there may be fewer funds available for the payment of dividends.

Recent Accounting Pronouncements

Amendments to IAS 1: Classification of Liabilities as Current or Non-current -

In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classifying liabilities as current or non-current. The amendments clarify:

- What is meant by a right to defer settlement;

- That a right to defer must exist at the end of the reporting period;

- That classification is unaffected by the likelihood that an entity will exercise its deferral right; and

- That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification.

The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and must be applied retrospectively. The Group is currently assessing the impact the amendments will have on current practice and whether existing loan agreements may require renegotiation.

Reference to the Conceptual Framework – Amendments to IFRS 3 -

In May 2020, the IASB issued Amendments to IFRS 3 Business Combinations - Reference to the Conceptual Framework. The amendments are intended to replace a reference to the Framework for the Preparation and Presentation of Financial Statements, issued in 1989, with a reference to the Conceptual Framework for Financial Reporting issued in March 2018 without significantly changing its requirements.

The Board also added an exception to the recognition principle of IFRS 3 to avoid the issue of potential ‘day 2’ gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 or IFRIC 21 Levies, if incurred separately. At the same time, the Board decided to clarify existing guidance in IFRS 3 for contingent assets that would not be affected by replacing the reference to the Framework for the Preparation and Presentation of Financial Statements. The amendments are effective for annual reporting periods beginning on or after January 1, 2022 and apply prospectively. The Group will apply changes in IFRS 3 prospectively for any business combination.

Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 -

In May 2020, the IASB issued Property, Plant and Equipment — Proceeds before Intended Use, which prohibits entities deducting from the cost of an item of property, plant and equipment, any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss. The amendment is effective for annual reporting periods beginning on or after January 1, 2022 and must be applied retrospectively to items of property, plant and equipment made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment.

The amendments are not expected to have a material impact on the Group due to there are no proceeds from selling items produced, while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management during the years 2021, 2020 and 2019.

Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37 -

In May 2020, the IASB issued amendments to IAS 37 to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making. The amendments apply a “directly related cost approach”. The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract. The amendments are effective for annual reporting periods beginning on or after January 1, 2022. The Group evaluated and concluded that there are no changes as a consequence of the application of the amendments.

IFRS 9 Financial Instruments – Fees in the ‘10 per cent’ test for derecognition of financial liabilities -

As part of its 2018-2020 annual improvements to IFRS standards process the IASB issued an amendment to IFRS 9. The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by either the borrower or lender on the other’s behalf. An entity applies the amendment to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment. The amendment is effective for annual reporting periods beginning on or after January 1, 2022 with earlier adoption permitted. The Group evaluated and concluded that there are no changes as a consequence of the application of the amendments.

Definition of Accounting Estimates - Amendments to IAS 8 -

In February 2021, the IASB issued amendments to IAS 8, in which it introduces a definition of ‘accounting estimates’. The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and the correction of errors. Also, they clarify how entities use measurement techniques and inputs to develop accounting estimates. The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and apply to changes in accounting policies and changes in accounting estimates that occur on or after the start of that period. Earlier application is permitted as long as this fact is disclosed. The Group will apply changes in IAS 8 prospectively for any business combination.

Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2 -

In February 2021, the IASB issued amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements, in which it provides guidance and examples to help entities apply materiality judgments to accounting policy disclosures. The amendments aim to help entities provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures. The amendments to IAS 1 are applicable for annual periods beginning on or after January 1, 2023 with earlier application permitted. Since the amendments to the Practice Statement 2 provide non-mandatory guidance on the application of the definition of material to accounting policy information, an effective date for these amendments is not necessary. The Group is currently assessing the impact of the amendments to determine the impact they will have on the Group’s accounting policy disclosures.

C.Research and Development

Not applicable.

D.Trend Information

Other than as disclosed in this Annual Report, we are not aware of any trends, uncertainties, demands, commitments, or events which are reasonably likely to have a material effect upon our net sales or revenues, income from continuing operations, profitability, liquidity or capital resources, or that would cause reported financial information to be not necessarily indicative of future operating results or financial condition.

119

For our exploration activities, there is no production, sales or inventory in a conventional sense. Our financial success is dependent upon the extent to which we are capable of discovering mineralization and the economic viability of exploration properties. The construction and operation of such properties may take years to complete and the resulting income, if any, cannot be determined with certainty. Further, the sales value of mineralization discovered by us is largely dependent upon factors beyond our control, including the market value of the metals produced at any given time.

E.Off-Balance Sheet Arrangements

There are no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors.

F.Reserved

G.Reconciliation of Costs Applicable to Sales and Cost Applicable to Sales per Unit Sold

Cost applicable to sales and Cost applicable to sales per unit of mineral sold are not measures of financial performance under IFRS, and may not be comparable to similarly titled measures of other companies. We consider Cost applicable to sales and Cost applicable to sales per unit of mineral sold to be key measures in managing and evaluating our operating performance. These measures are widely reported in the precious metals industry as a benchmark for performance, but do not have standardized meanings. You should not consider Cost applicable to sales or Cost applicable to sales per unit of mineral sold as alternatives to cost of sales determined in accordance with IFRS as indicators of our operating performance. Cost applicable to sales and Cost applicable to sales per unit of mineral sold are calculated without adjusting for by-product revenue amounts.

In calculating these figures, we utilize financial records maintained with respect to the various mining units and subsidiaries, each on a standalone basis. Within the standalone accounts for each mining unit or subsidiary, we then allocate cost of sales (excluding depreciation and amortization), exploration in operating units and selling expenses in the proportion to each mineral’s commercial value (realized price multiplied by volume sold).

The tables below set forth (i) a reconciliation of consolidated Cost of sales, excluding depreciation and amortization to consolidated Cost applicable to sales, (ii) reconciliations of the components of Cost applicable to sales (by mine and mineral) to the corresponding consolidated line items set forth on our consolidated statements of profit or loss for the years ended December 31, 2021 and 2020 and (iii) reconciliations of Cost of sales, excluding depreciation and amortization to Cost applicable to sales for each of our mining units. The amounts set forth in Cost applicable to sales and Cost applicable to sales per unit sold for each mine and mineral indicated in the tables below can be reconciled to the amounts set forth on our consolidated statements of profit or loss for the years ended December 31, 2021 and 2020 by reference to the reconciliations of Cost of sales, excluding depreciation and amortization (by mine and mineral), Selling Expenses (by mine and metal) expenses and Exploration in operating units (by mine and mineral) to consolidated Cost of sales, excluding depreciation and amortization, consolidated Selling Expenses and Consolidated Exploration in operating units expenses, set forth below.

YANACOCHA

Introduction

The following discussion should be read in conjunction with (i) the Yanacocha Consolidated Financial Statements as of December 31, 2020 and 2021 and for the years ended December 31, 2019, 2020 and 2021 and the related Notes thereto included elsewhere in this Annual Report, and (ii) Item 5 to our 2020 20-F. The Yanacocha Consolidated Financial Statements are prepared and presented in accordance with IFRS as issued by the IASB and in U.S. Dollars.

127

A.Operating Results

Overview

Yanacocha was established in Peru in January 1992 and commenced production activities in 1993. Yanacocha’s operations are located in the Andes Mountains in Northern Peru, in the area of Cajamarca which is located approximately 600 kilometers north of Lima and north of the city of Cajamarca, at an altitude of 4,000 meters above sea level. Yanacocha is 51.35% owned by Newmont Second Capital Corporation, 43.65% owned by Buenaventura through our wholly owned subsidiary Condesa and 5% owned by Summit Global Management II VB. Yanacocha is managed by Newmont International Services. See “Item 4. Information on the Company—Yanacocha—B. Business Overview—Management of Yanacocha—General Manager/Management Agreement.”

The table below highlights Yanacocha’s key financial and operating results:

Summary of Financial and Operating Performance

	Year Ended December 31,
	2021	2020
Gold sales (in thousands of US$)	471,069	592,394
Gold sold (oz.)	262,587	339,068
Average gold price received (US$/oz.)	1,794	1,747
Other operating expenses, net (in thousands of US$)	(36,291)	(34,322)
Loss on assets held for sale	(152,224)	—
Impairment reversal	97,592	—
Loss for the year (in thousands of US$)	(967,682)	(165,449)

Gold sales. Gold sales decreased 22% primarily due to lower mill throughput as a result of the ramp down of the mill, partially offset by higher leach pad production as a result of higher leach recoveries.

Costs applicable to sales. Costs applicable to sales include: (i) operating costs, consisting primarily of direct production costs such as mining and treatment of the ore, which are the most significant components of costs applicable to sales, (ii) depreciation and amortization, (iii) write downs of ore on leach pads to net realizable value expense, (iv) reclamation expenses and (v) other costs. Costs applicable to sales per gold ounce increased 88% primarily due to higher year-end provision for mine closure update, as a consequence of revised water treatment costs. Depreciation and amortization per gold ounce increased 8% primarily due to higher depreciation rates from higher ounces from Quecher Main and La Quinua, considering that during the previous year the operation was placed on care and maintenance.

Other operating expenses, net. Other operating expenses, net decreased by 5.7% or US$1,9 million from 2020 to 2021, primarily due to higher exploration and advanced projects expenses.

Loss on assets held for sale, During 2021, Yanacocha entered into a binding agreement to sell certain equipment and assets related to the Conga project, for total cash proceeds of US$68 million, net of associated cost for sale for US$46 million. The book value of these assets before classification as held for sale was US$174 million (includes the book value of assets included in the sales agreement for US$79 million) book value of services and other assets capitalized for US$95 million, accordingly, Yanacocha recognized an expense of US$152 million.

Impairment reversal, Yanacocha recognized an impairment reversal of Yanacocha CGU of US$97.6 million, mainly explained for the increase of the gold prices and the near development of the Sulfides project.

Income tax benefit (expense). Yanacocha’s financial and operating results included an income and mining tax expense of US$51 million in 2021 compared to an expense of US$53 million in 2020. The difference was driven by a higher loss before income tax in 2021 for US$ 917 million as compared to a loss before tax of US$112 million in 2020 and higher valuation allowance on deferred income tax assets in 2021 for $ 253 million (US$57 million in 2020).

Results of Operations for the Years Ended December 31, 2021 and 2020

Sales

Gold sales. Gold sales decreased 22% primarily due to lower mill throughput as a result of the ramp down of the mill, partially offset by higher leach pad production as a result of higher leach recoveries. Yanacocha has not engaged in gold price hedging activities, such as forward sales or option contracts, to minimize its exposure to fluctuations in the price of gold.

Costs applicable to sales

Costs applicable to sales for the year ending December 31, 2021 and 2020 comprised:

	2021	2020
	(US$ in thousands)
Beginning balance of finished goods and in-process	222,258	302,382
Beginning balance of provision for net realizable value	(13,287)	(47,925)
Royalties to related parties	15,928	18,638
Mining royalties to the government	6,553	7,570
Consumption of supplies	111,532	138,041
Personnel expenses	41,751	61,298
Other services	40,211	31,864

Power	12,933	20,241
Depreciation and amortization	151,843	140,252
Workers’ profit participation	12,059	17,199
Incremental costs related to COVID-19 pandemic and care and maintenance	20,309	43,672
Provision for mine closure	823,889	124,780
Ending balance of provisions for net realizable value	1,259	13,287
Ending balance of finished goods and in-process	(211,845)	(222,258)
	1,252,710	666,456

Costs applicable to sales. Costs applicable to sales include: (i) operating costs, consisting primarily of direct production costs such as mining and treatment of the ore, which are the most significant components of costs applicable to sales, (ii) depreciation and amortization, (iii) write downs of ore on leach pads to net realizable value expense and (iv) other costs. Costs applicable to sales increased by 88% or US$586 million from 2020 to 2021. Costs applicable to sales per ounce of gold increased by 143% from US$1,965 per ounce in 2020 to US$4,771 per ounce in 2021.

Operating costs decreased by 17% from US$269 million in 2020 to US$224 million in 2021. Operating costs consist primarily of drilling, blasting, loading, hauling, leaching, milling and metal recovery costs

129

Provision for mine closure of US$824 million are due to a non-cash charge to reclamation expenses for the year ended December 31, 2021 mainly related to the areas of Yanacocha’s operations no longer in production. The increase to the reclamation obligation in 2021 is mainly due to water treatment costs.

Workers’ profit participation decreased by 29%, from US$17 million in 2020 to US$ 12 million in 2021. This decrease was driven by lower revenues. Workers’ profit participation expense is calculated based on taxable net income, in accordance with Peruvian labor legislation.

The portion of leach pad inventory write-downs associated with costs applicable to sales decreased from US$34.6 million to US$ 12.0 million due to higher realizable price.

Depreciation, depletion and amortization increased by 8% from US$140 million in 2020 to US$ 152 million in 2021. This increase was attributable principally to unit of production amortization from Quecher Main and La Quinua related assets.

Administrative expenses

Administrative expenses for the years ended December 31, 2021 and 2020 were composed of:

	2021	2020
	(US$ in thousands)
Management expenses	635	874
Other	269	353
	904	1,227

Other operating expenses, net

Other operating expenses, net for the years ended December 31, 2021 and 2020 were as follows:

	2021	2020
	(US$ in thousands)
Cost of sales from the sale of fixed assets	—	30
Exploration and advance project	23,619	19,279
Severance program	5,769	4,454
Tax fine	234	11
Write-off of fixed assets	613	460
Revenue from sale of fixed assets	(1,009)	(40)
Social responsibility commitments	—	6,730
Others, net	7,065	3,398
	36,291	34,322

Exploration and advanced project costs increased from US$20 million in 2020 to US$24 million in 2021. This increase was mainly driven by the higher drilling activities in current year, given the paralyzed impact from prior period due to COVID-19.

Reversal of impairment of long-lived assets

In 2021, Yanacocha Management identified as an impairment reversal indicator the significant increase in the long-term gold price, as a result the Company had to determinate the recoverable amount for its CGU Yanacocha and CGU Conga. As a result of this analysis the Company concluded that, for Conga, no additional impairment or impairment reversal was required to be recorded as the recoverable amount exceeded the carrying amount of the CGUs’ assets. However, for the Yanacocha assets, the Company concluded that a reversal of impairment loss was required as the recoverable amount was higher than the carrying amount of the CGU’s assets. The recoverable amount for the Yanacocha CGU was based on the FVLD using estimated future cash flows expected to be generated from the continued use of the CGU’s using market assumptions. Based on the fair value calculated, the Company recognized an impairment reversal on Yanacocha of $97,592.

130

Income tax provision.

Yanacocha’s financial and operating results included income and mining tax expenses of US$ 51 million in 2021 compared to US$53 million in 2020. This decrease was driven by the higher valuation allowance on deferred income tax assets in 2021 for US$252 million (US$57 million in 2020), favorable effect of change in translation to US dollars for US$36 million (unfavorable US$23 million in 2020), offset by the higher loss before income tax in 2021 for US$917 million (US$112 million loss in 2020).

Net loss

Net loss increased by US$802.2 million, from net loss of US$165.5 million in 2020 to net loss of US$ 967.7 million in 2021, mainly explained by the higher provision for mine closure driven by the higher future water treatment costs.

Results of Operations for the Years Ended December 31, 2020 and 2019

See “Item 5. Operating and Financial Review and Prospects” in our 2020 20-F for a comparative discussion of Yanacocha’s consolidated results of operations for the year ended December 31, 2020 and 2019.

B.Liquidity and Capital Resources

As of December 31, 2021, Yanacocha had cash and cash equivalents of US$693 million, substantially all of which were held in U.S. Dollars, as compared to US$871 million as of December 31, 2020.

Cash provided by operating activities

Yanacocha generated net cash flow from operations of US$13 million in 2021 and US$196 million in 2020. The net cash flow from operations in 2021 was -94% or US$183 million lower than in 2020. The decrease was primarily driven by lower Gold Sales.

Cash used in investing activities

Net cash used in investing activities was US$191 million in 2021 compared to US$143 million in 2020. The increase in cash used in investing activities was mainly due to higher purchase of property plant and equipment.

Cash used in financing activities

Net cash used in financing activities was US$0.2 million in 2021, as compared to cash used of US$0.3 million in 2020. There was no material variance.

The following table shows Yanacocha’s contractual obligations as of December 31, 2021:

	Payments due by Period (US$ in millions)
		Less than			More than
	Total	1 year	1-3 years	3-5 years	5 years

CERRO VERDE

Introduction

The following discussion should be read in conjunction with the Cerro Verde Financial Statements as of December 31, 2020 and 2021 and for the years ended December 31, 2019, 2020 and 2021 and the related Notes thereto included elsewhere in this Annual Report, and (ii) Item 5 to our 2020 20-F. The Cerro Verde Financial Statements are prepared and presented in accordance with IFRS as issued by the IASB.

A. Operating Results

Overview

We hold a 19.58% interest in Cerro Verde, which operates an open-pit copper and molybdenum mining complex located 20 miles southwest of Arequipa, Peru. The site is accessible by paved highway. The Cerro Verde mine has been in operation since 1976, and was previously owned by the Peruvian government before its privatization in 1993. Freeport-McMoRan Inc. holds a majority interest in Cerro Verde.

The Cerro Verde mine is a porphyry copper deposit that has oxide, secondary sulfide, and primary sulfide mineralization. The predominant oxide copper minerals are brochantite, chrysocolla, malachite and copper “pitch.” Chalcocite and covellite are the most important secondary copper sulfide minerals. Chalcopyrite and molybdenite are the dominant primary sulfides.

Cerro Verde’s operation consists of an open-pit copper mine, with a processing capacity of 548,500 metric tons-per-day that includes (i) concentrator facilities with a 409,500 metric ton-per-day capacity (361,500 metric tons-per-day prior to the expansion approved by the MEM during 2018), (ii) solution extraction and electrowinning (SX/EW) leaching facilities with leach copper production derived from a 39,000 metric ton-per-day crushed leach facility and (iii) a run-of-mine (ROM) leach system with a capacity of 100,000 metric tons-per-day. This SX/EW leaching operation has a production capacity of approximately 200 million pounds of copper per year.

On March 15, 2020, the Peruvian government issued a Supreme Decree and declaration of a National Emergency in its efforts to contain the outbreak of COVID-19. The order was initially for 15 days but was subsequently extended for different periods ultimately lasting through March 31, 2022.

132

During 2021, Cerro Verde milling rates at concentrator plants averaged 380,300 metric tons per day. During 2020, Cerro Verde temporarily went into a state of care and maintenance (in order to comply with government requirements) and adjusted its operations to prioritize critical activities and subsequently revised its operating plans (milling rates at concentrator plants averaged 331,600 metric tons per day). Subject to ongoing monitoring of COVID-19 protocols, Cerro Verde is targeting milling rates to increase to approximately 400,000 metric tons of ore per day during 2022.

Cerro Verde continues to update its “Plan for the Surveillance, Prevention and Control of COVID-19” at work. The implementation of these prevention, early detection and response measures and actions helps to control the risk of spread and health impact caused by the COVID-19 pandemic during the development of operational activities.

The available fleet consists of fifty-four 300-metric-ton haul trucks and ninety-three 245-metric-ton haul trucks (21 of which are currently on standby) and three 363-metric-ton leased haul trucks loaded by 13 electric shovels with bucket sizes ranging in size from 33 to 57 cubic meters and two hydraulic shovels with a bucket size of 21 cubic meters (both of which are currently on standby). This fleet is capable of moving an average of approximately 970,000 metric tons of material per day.

Copper cathodes and concentrate production that are not sold locally are transported approximately 113 kilometers by truck and by rail to the Port of Matarani for shipment to international markets. Molybdenum concentrate is transported by truck to either the Ports of Callao or Matarani for shipment.

Cerro Verde currently receives electrical power, including hydro-generated power, under long-term contracts with electric utility companies. Water for Cerro Verde’s processing operations comes from renewable sources through a series of storage reservoirs on the Rio Chili watershed that collect water primarily from seasonal precipitation and from wastewater collected from the city of Arequipa and treated at a wastewater treatment plant. Cerro Verde believes that the operation has sufficient water resources to support current operations.

Presented in the table below are certain summary financial and operating data regarding Cerro Verde for the years ended December 31, 2020 and 2021:

(2) Reserve calculations are derived from “Item 3. Key Information – A. Selected Financial Data.” Cerro Verde used US$2.50 per pound of copper to determine copper as of December 31, 2021. The calculation or estimation of proven and probable ore reserves for Cerro Verde may differ in some respects from the calculations of proven and probable ore reserves for us and for Yanacocha located elsewhere in this Annual Report. According to Cerro Verde, ore estimates for Cerro Verde are based upon engineering evaluations of assay values derived from samplings of drill holes and other openings. Cerro Verde’s ore estimates include assessments of the resource, mining and metallurgy, as well as consideration of economic, marketing, legal, environmental, social and governmental factors, including projected long-term prices for copper and molybdenum and Cerro Verde’s estimate of future cost trends.

Cerro Verde Mining Royalties

On June 23, 2004, Law 28258 was approved, which requires the holder of a mineral concession to pay a royalty in return for the exploitation of metallic and non-metallic minerals. The royalty is calculated using different rates applicable to the value of concentrate or its equivalent according to the international price of the commodity published by the Ministry of Energy and Mines. Prior to January 1, 2014, the Company determined that these royalties were not applicable because it operated under the 1998 Stability Agreement with the Peruvian government. However, beginning January 1, 2014, the Company began paying royalties calculated on operating income with rates between 1% to 12% and a new special mining tax for its entire production base under its current 15-year tax stability agreement, which became effective January 1, 2014. The amount to be paid for the mining royalty will be the greater of a progressive rate of the quarterly operating income or 1% of quarterly sales.

SUNAT assessed mining royalties on materials processed by the Company´s concentrator, which commenced operations in late 2006. These assessments cover the period December 2006 to December 2013. The Company contested each of these assessments because it considers that its 1998 Stability Agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing such minerals. No assessments can be issued for years after 2013, as the Company began paying royalties on all of its production in January 2014 under its new 15-year stability agreement.

Since 2017, the Company has recognized the related expense for the royalty and special mining tax assessments for the period December 2006 through the year 2013. Since 2014, the Company has been paying the disputed assessments under protest for the period from December 2006 through December 2013 under installment payment programs granted through scheduled monthly installments. In August 2021, the Company decided to pay in advance and under protest the total pending installment debt. As of December 31, 2021, the Company has made total payments of S/2.9 billion under these installment programs (US$791.9 million based on the date of payment exchange rate).

During February 2020, the Company requested the initiation of an arbitration proceeding against the Republic of Peru before the International Centre for Settlement of Investment Disputes and on October 19, 2021, the Company formally filed the arbitration claim. On March 31, 2021, Superintendence Resolution 044-2021/SUNAT was published in which new default monthly interest rates were established effective April 1, 2021. The default interest rate in national currency changes from 1% to 0.9%.

Critical Accounting Policies

Cerro Verde has furnished us with a discussion of its critical accounting policies and methods used in the preparation of its financial statements. Critical accounting policies are defined as those that are reflective of significant judgments and uncertainties and could potentially impact results under different assumptions and conditions. Note 2 to the Cerro Verde Financial Statements includes a summary of the significant accounting policies and methods used in the preparation of the Cerro Verde Financial Statements. The following is a brief discussion of the identified critical accounting policies and the estimates and judgments made by Cerro Verde.

Contingencies

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential amount of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

134

Stripping cost

Cerro Verde incurs waste removal costs (stripping costs) during the development and production phases of its surface mining operations. During the production phase, stripping costs (production stripping costs) can be incurred both in relation to the production of inventory in that period and the creation of improved access and mining flexibility in relation to ore to be mined in the future. The former are included as part of the costs of inventory, while the latter are capitalized as asset stripping activities, where certain criteria are met.

Inventories

Net realizable value tests are performed at least annually and represent the estimated future sales price of the product based on prevailing spot metals prices, less estimated costs to complete production and bring the inventory to sale. Additionally, in calculating the net realizable value of Cerro Verde’s long-term stockpiles, Cerro Verde’s management also considers the time value of money.

Mill and leach stockpiles generally contain lower grade ores that have been extracted from the ore body and are available for copper recovery. Mill stockpiles contain sulfide ores and recovery of metal is through milling and concentrating. Leach stockpiles contain oxide ores and certain secondary sulfide ores and recovery of metal is through exposure to acidic solutions that dissolve contained copper and deliver it in a solution to extraction processing facilities.

Because it is generally impracticable to determine copper contained in mill and leach stockpiles by physical count, a reasonable estimation method is employed. The quantity of material delivered to mill and leach stockpiles is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blast hole cuttings determine the estimated copper grades of material delivered to mill and leach stockpiles.

Expected copper recovery rates for mill stockpiles are determined by metallurgical testing. The recoverable copper in mill stockpiles, once entered into the production process, can be produced into copper concentrate almost immediately.

Determination of mineral reserves

Mineral reserves are the parts of mineral deposit ore that can be economically and legally extracted from the mine concessions. Cerro Verde estimates its mineral reserves based on information compiled by individuals qualified in reference to geological data about the size, depth and form of the ore body, and requires geological judgments in order to interpret the data.

The estimation of recoverable reserves involves numerous uncertainties with respect to the ultimate geology of the ore body, including quantities, grades and recovery rates. Estimating the quantity and grade of mineral reserves requires Cerro Verde to determine the size, shape and depth of the ore body by analyzing geological data. In addition to the geology, assumptions are required to determine the economic feasibility of mining the reserves, including estimates of future commodity prices and demand, future requirements of capital and production costs and estimated exchange rates. Revisions in reserve or resource estimates have an impact on the value of mining properties, property, plant and equipment, provisions for cost of mine closure, recognition of assets for deferred taxes and depreciation and amortization of assets.

Units of production Depreciation

Estimated mineral reserves are used in determining the depreciation and/or amortization of mine-specific assets. This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, is impacted by both its physical life limitations and present assessments of economically recoverable reserves of the mine property where the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves.

135

Expected copper recovery rates for leach stockpiles are determined using small-scale laboratory tests, historical trends and other factors, including mineralogy of the ore and rock type. Total copper recovery in leach stockpiles can vary significantly depending on several variables, including type of copper recovery, mineralogy and the size of the rock. For newly placed material of active stockpiles, as much as 80% of total copper recovery may be extracted during the first year, and the remaining copper may be recovered over many years. Processes and recovery rates are monitored continuously, and recovery rate estimates are adjusted periodically as additional information becomes available and as related technology changes.

Provision for remediation and Mine Closure

Cerro Verde assesses its provision for remediation and mine closure quarterly. It is necessary to make estimates and assumptions in determining this provision, including cost estimates of activities that are necessary for the rehabilitation of the site, technological and regulatory changes, interest rates and inflation rates. As discussed in Note 2(k) to the Cerro Verde Financial Statements, estimated changes in the fair value of the provision for remediation and mine closure or the useful life of the related assets are recognized as an increase or decrease in the book value of the provision and related asset retirement cost (“ARC”) in accordance with IAS 16, “Property, Plant and Equipment.”

According to Cerro Verde’s accounting policies, the provision for remediation and mine closure represents the present value of the costs that are expected to be incurred in the closure period of the operating activities of Cerro Verde. Closure budgets are reviewed regularly to take into account any significant change in the studies conducted. Nevertheless, the closure costs of mining units will depend on the market prices for the closure work required, which would reflect future economic conditions. Also, the timing of disbursements depends on the useful life of the mine, which is based on estimates of future commodity prices.

If any change in the estimate results in an increase to the provision for remediation and mine closure and related ARC, Cerro Verde shall consider whether or not this is an indicator of impairment of the assets and will apply impairment tests in accordance with IAS 36, “Impairments of Assets.”

Impairment of Long-lived Assets

Cerro Verde has determined that its operations consist of one cash generating unit. Therefore, Cerro Verde’s operations are evaluated at least annually in order to determine if there are impairment indicators. If any such indication exists, Cerro Verde makes an estimate of the recoverable amount, which is the greater of the fair value less costs to sell and the value in use. These assessments require the use of estimates and assumptions, such as long-term commodity prices, discount rates, operating costs and others.

Fair value is defined as the amount that would be obtained from the sale of the asset in an arm’s-length transaction between willing and knowledgeable parties. The fair value of assets is generally determined as the current value of future cash flows derived from the continuous use of the asset, which includes estimates, such as the cost of future expansion plans and eventual disposal, while applying assumptions that an independent market participant may take into account. The cash flows are discounted by applying a discount rate that reflects the current market, the time value of money and the risks specific to the asset.

Once Cerro Verde has identified its production stripping costs for each surface mining operation, it identifies the separate components of the ore bodies for each of its mining operations. An identifiable component is the specific volume of the ore body that is made more accessible by the stripping activity. Significant judgment is required to identify and define these components, and also to determine the expected volumes (e.g., in tons) of waste to be stripped and ore to be mined in each of these components.

Results of Operations for the Years Ended December 31, 2021 and 2020

Sales. Sales, including mark-to-market adjustments for pounds of copper pending settlement, increased by 65%, from US$2,538.6 million in 2020 to US$4,199.4 million in 2021, principally due to higher copper prices. The following table reflects the average realized price and volume sold of copper (both cathode and concentrate) during the years ended December 31, 2020 and 2021:

	Year ended December 31,
	2020	2021	Variation
Average price
Copper (US$per ton)	6,766	10,449	54	%
Volume sold (unaudited)
Copper (in metric tons)	375,185	401,886	7	%

Average realized copper prices per ton increased from US$6,766 in 2020 to US$10,449 in 2021. The volume of copper sold increased from 375,185 tons in 2020 to 401,886 metric tons in 2021. The combined effect of these changes resulted in a US$1,660.9 million increase in income from sales in 2021 compared to 2020.

Total costs of sales of goods. Total costs of sales of goods increased from US$1,809.3 million in 2020 to US$2,155.1 million in 2021, due mainly to the net effect of the following:

(a) Materials and supplies and third-party services increased by 23%, from US$746.2 million in 2020 to US$919.2 million in 2021, primarily as a result of an increase in operating costs given the progressive restoration of operations after the gradual loosening of restrictions imposed by the Peruvian government as a result of the COVID-19 pandemic in 2020.

(b) Labor costs, including workers’ profit sharing, increased by 48%, from US$288.1 million in 2020 to US$425.5 million in 2021, mainly due to bonuses granted to workers as part of new Union Agreements signed in 2021 and higher profit sharing.

(c) Benefits associated with work in process inventories decreased by 66%, from US$(49.6) million in 2020 to US$(16.6) due to higher pounds removed from mill and leach stockpiles.

Total operating expenses. Operating expenses decreased by 9%, from US$130.0 million in 2020 to US$118.0 million in 2021 due mainly to the following:

(a) Other operating (expenses), income net decreased by 75%, from US$32.3 million in 2020 to US$8.1 million in 2021, primarily associated with the excess of salary limit in workers’ profit sharing (recognized in year 2020 corresponding to previous years assessments of $ 17.1 million) and lower royalty non-income tax (based on revenues) of $ 10.8 million.

(b) Selling expenses increased by 12%, from US$97.7 million in 2020 to US$109.9 million in 2021, mainly due to higher ocean freight rates coupled with an increase in the volume of copper concentrate sold.

Income tax. Income tax expense, including current and deferred expense, increased by 211%, from an expense of US$236.9 million in 2020 to an expense of US$735.7 million in 2021 primarily due to higher profit generated in 2021.

Profit of the year. As a result of the foregoing, profit of the year increased by 334%, from US$274.5 million in 2020 to US$1,191.5 million in 2021. As a percentage of net sales, net income was 28% in 2021, compared to 11% in 2020.

Results of Operations for the Years Ended December 31, 2020 and 2019

See “Item 5. Operating and Financial Review and Prospects” in our 2020 Form 20-F for a comparative discussion of Cerro Verde’s consolidated results of operations for the year ended December 31, 2020 and 2019.

B. Liquidity and Capital Resources

As of December 31, 2021, Cerro Verde had cash and cash equivalents of US$937.7 million, compared to US$533.7 million as of December 31, 2020.

Cash provided by operating activities for the years ended December 31, 2021 and 2020. Net cash and cash equivalents provided by operating activities were US$1,693.3 million in 2021, compared to net cash provided by operating activities of US$638.3 million in 2020. This change in net cash flow provided by operating activities in 2021 compared to 2020 was mainly attributable to the following factors:

An increase in proceeds from sales from US$2,418 million in 2020 to US$4,234 million in 2021.

An increase in income tax payments and royalty case payments from US$226 million in 2020 to US$737 in 2021.

An increase in operational payments from US$1,647 million in 2020 to US$2,018 million in 2021 primarily associated with higher operational cost (higher throughput at mills associated with lower restrictions associated with COVID-19), higher commodity prices, and higher labor costs (profit sharing and bonuses related to new union labor agreements).

Cash used in investing activities for the years ended December 31, 2021 and 2020. Net cash used in investing activities increased from US$376.6 million in 2020 to US$271.7 million.

Cash used in financing activities for the years ended December 31, 2021 and 2020. Net cash and cash equivalents used in financing activities was US$912.7 million in 2021, compared to net cash used in financing activities of US$314.4 million in 2020. The increase in net cash used in financing activities was primarily due to dividend payments of US$700 million in 2021 (there were no payments made in 2020). The increase was partially offset by lower syndicated bank loan repayment of US$105 million.

The following table shows Cerro Verde’s contractual obligations as of December 31, 2021:

	Payments due by Period (US$ in millions)
		Less than 1	1-5	More than 5

141

C. Board Practices

Audit Committee

The Audit Committee, which is composed entirely of independent directors as defined in Section 303A.02 of the New York Stock Exchange’s Listed Company Manual, is responsible for assisting the Board in the appointment of independent auditors, upon delegation of such responsibility by the shareholders at the general meeting of shareholders (the “General Meeting”) and reviewing the scope of internal and external audits. The Audit Committee also reviews compliance with internal control systems, reviews our annual and quarterly Consolidated Financial Statements before their presentation to the Superintendencia del Mercado de Valores, or the SMV (formerly known as the Comisión Nacional Supervisora de Empresas y Valores (National Supervisory Commission of Business and Securities)) (CONASEV), the Bolsa de Valores de Lima (Lima Stock Exchange) and the SEC and maintains the integrity of the preparation of audits. The members of the Audit Committee are Messrs. Zaldívar, Ortiz-de-Zevallos and de la Torre.

Innovation and Sustainability Committee

The Innovation and Sustainability Committee is responsible for monitoring initiatives and practices related to Innovation and Sustainability. The members of the Innovation and Sustainability Committee for 2021 were Miss Nicole Bernex, Messrs. Roque Benavides, Raúl Benavides and de la Torre.

D. Employees

As of December 31, 2021 we, including our subsidiaries and Coimolache, had 3,045 employees (including permanent and temporary employees). In addition, we have entered into arrangements with independent contractors that employed 9,258 workers at our operations. We have sought to strengthen our workforce by implementing a qualifications-based hiring policy and, with respect to employees working in the mines, reducing the average age of the workforce. As of December 31, 2021, the average tenure of Buenaventura’s permanent laborers was approximately 10.05 years.

Of the 2,957 permanent employees (considers employees working on an indefinite term contract) employed by Buenaventura, its subsidiaries and Coimolache, approximately 50% are members of 14 different labor unions (including five unions for clerical workers and nine unions for laborers), representing all aforementioned clerical workers and laborers in collective negotiations. There are also six unions for workers employed by independent contractors that were formed over the last nine years in our mines at Uchucchacua, Orcopampa, Tambomayo, Julcani, El Brocal and Coimolache.

Each of the labor unions is company-based with an affiliation to a national union. Administrative personnel are not represented by unions. Labor relations for unionized and non-unionized employees in our production facilities, including compensation and benefits, are governed by collective bargaining agreements, the terms and length of which are negotiated throughout the year as the various collective bargaining agreements come up for renewal. These collective bargaining agreements are typically one year in length and set wages for the applicable period and benefits such as overtime, bonuses and family benefits.

In May 2021 we experienced a two-day work stoppage at the Uchucchacua mine called by the workers’ union for contractor companies. In September 2021 we also experienced a three-day work stoppage at the same mine and called by the same union.

142

Compensation received by our employees includes salary, other cash payments (such as overtime, vacation pay and bonuses, including, but not limited to, high altitude and underground mining bonuses) and non-cash benefits. Non-cash benefits include medical insurance, life insurance and training programs for workers and administrative staff. For mine and processing plant workers, benefits also include transportation services, meals or food allowances, education for children of our employees and housing, hospitals and a full range of social services for our permanent employees and their families at town sites near our mines in compliance with mining regulations. We voluntarily provide power, water and sewage services for the camp and houses of the workers as well as for certain towns nearby. In addition, pursuant to a profit-sharing plan mandated by Peruvian labor legislation, employees of mining companies in Peru are entitled to receive the employee profit sharing amount equivalent to 8% of the annual pre-tax profits of their employer, 50% of such profits to be distributed based on the number of days each employee worked during the preceding year and the remaining 50% of such profits to be distributed based on the aggregate annual salary of each employee. Effective January 1, 1997, the annual payment to each employee under the profit sharing plan cannot exceed 18 times such employee’s monthly salary, and any difference between the employee profit sharing amount and the aggregate amount paid to employees must be contributed by us to FONDOEMPLEO, a fund established to promote employment and employee training.

Currently, we have (and strictly comply with) a Wage Policy that helps ensure equitable compensation under the principle of non-discrimination. The Wage Policy meets with the parameters established by Law N°30709, which forbids salary discrimination between men and women, as well as the related Regulations approved by Supreme Decree N°002-2018-TR.

Under Peruvian law, we may dismiss workers for just cause after completing certain formal procedures. In addition, several decisions adopted by the Peruvian Constitutional Court, holding that an employee is entitled for reinstatement if no cause for dismissal is expressed by the employer or for failure to present evidence supporting the employer’s grounds, have limited our ability to dismiss a worker without cause.

In the absence of just cause, workers are typically terminated by paying the applicable worker a layoff indemnification based on, at least, an amount equal to one and a half month’s salary for each full year worked plus the pro rata portion for any uncompleted year, collectively, not to exceed in the aggregate 12-months’ salary. The use of this method is subject to the worker’s acceptance.

Regardless of the cause for termination, all employees are entitled to a severance payment. Such payment is equal to one month’s salary (including an amount assigned for the value of other benefits), for each full year worked plus the pro rata portion for any uncompleted year. Pursuant to the Peruvian labor laws, said severance payments are deposited in a special bank account selected by each employee and for the benefit of such employee, in both May and November of each year (approximately 50% of a monthly salary each time). Workers may withdraw such funds in excess of four times the worker’s gross monthly salary. Upon termination, the remaining balance may be withdrawn by the worker for any reason.

We are subject to the recently enacted Supreme Decree N°001-2022-TR. This decree amended the Regulations of Law N°29245, a law governing the rules regarding outsourcing services. Under the new decree, a subject company is forbidden from outsourcing all activities considered to be part of the company’s “nuclear business.” Companies may still outsource specialized activities that are not part of the company’s nuclear business. Prior to this amendment, we were, in accordance with Law N°29245, allowed to outsource any part of the productive process. The Company expects to (and expects that many other employees will) challenge the validity of Supreme Decree N°001-2022-TR, but the initiation and outcome of these proceedings is not known.

Our permanent employees receive the benefit of one of two types of pension arrangements. All workers can choose to enroll in a public pension fund managed by the state (the “ONP” system) or in a private pension fund (the AFP system). We are required to withhold from each of the salaries of the employees enrolled in the ONP system 13% of such employee’s salary, and pay such amount to the ONP system and withhold from the salary of each employee enrolled in the AFP system approximately 12.5% of such employee’s salary, and pay such amounts to the respective AFP (exact amount varies from one AFP to another). Additionally, for workers involved in mining and metallurgical processes, an additional 2% is withheld from their salaries, and we contribute an additional 2% to increase their pension funds. We have no liability for the performance of these pension plans. Our independent contractors are responsible for covering severance and pension payments with respect to their employees.

In addition, we pay EsSalud, the Social Health Insurance Institute of Peru, 9% of our total payroll for general health services for all permanent employees. Further, Law No. 26790 also requires us to provide private insurance representing an average payment equal to 1.30% of the payroll of covered employees for employment-related incapacity and death for blue collar employees and other employees exposed to mining-related hazards.

As of March 31, 2022, we estimate that 221,265,398 Common Shares were held in the U.S., which represented approximately 87.21% of Common Shares outstanding. The number of institutional record holders of our Common Shares (or of ADSs representing our Common Shares) in the U.S. was 48 institutions.

B. Related Party Transactions

Except as otherwise disclosed herein, no director, senior officer, principal shareholder or any associate or affiliate thereof had any material interest, direct or indirect, in any transaction since the beginning of our last financial year that has materially affected us, or in any proposed transaction that would materially affect us. Except as otherwise disclosed herein, we have entered into no transactions with parties that are not “related parties” but who would otherwise be able to negotiate terms not available on an arm’s-length basis. From time to time in the ordinary course of business, we enter into management, exploration, mine construction, engineering and employment contracts with joint venture companies in which one or more of our direct or indirect subsidiaries holds equity or partnership interests.

The compensation of our key executives (including the related income taxes we assumed in connection therewith) amounted to US$14.4 million in 2019, US$13.4 million in 2020 and US$12.1 million in 2021. Please refer to Note 32(d) to the Consolidated Financial Statements for further information.

Chaupiloma is the legal owner of the mineral rights operated by Yanacocha and receives a 3% royalty based on quarterly sales, after deducting refinery and transportation costs. Royalties amounted to US$22.3 million, US$18.6 million, and US$15.9 million in 2019, 2020 and 2021, respectively, and are presented as royalty income in our consolidated statements of profit (loss).

Condesa did not receive cash dividends from its investment in Yanacocha in 2019, 2020, or 2021.

145

In 2019 and 2021, we received cash dividends from Sociedad Minera Cerro Verde S.A.A. in an amount of US$29.4 million, US$137.1 million, respectively. We did not receive cash dividends in 2020 from this investment.

We received cash dividends from Coimolache of approximately US$4.0 million in 2019, US$3.6 million in 2020, and US$11.3 million in 2021.

In November 2000, Conenhua signed an agreement with Yanacocha for the construction and operation of a 220 kW transmission line between Trujillo and Cajamarca, a 60 kW transmission line between Cajamarca and La Pajuela, and the Cajamarca Norte substation; this agreement also encompassed activities necessary to enlarge the Trujillo substation. In June 2006, an addendum to this contract extended the completion date to June 2007. Concurrently, we and Yanacocha signed a 10-year agreement covering electric energy transmission and infrastructure operation beginning in 2007. In exchange for us operating and managing the transmission project, Yanacocha pays a fee of US$3.7 million with annual maturities. The annual revenues for these services amounted to approximately US$0.3 million in 2019, US$0.3 million in 2020 and US$0.3 in 2021.

Legal Proceedings

SUNAT litigation

Buenaventura is involved in legal proceedings against SUNAT in connection with SUNAT’s refusal to recognize Buenaventura’s deductions with respect to contracts for physical deliveries and certain contractual payments made by the Company during the years 2007 and 2008, as well as tax loss, which was offset in 2009 and 2010.

During 2007 and 2008, Buenaventura modified its gold client contracts, shifting from a fixed price arrangement to a variable price arrangement, which allowed the Company to appropriately benefit from improved market prices. This change incurred significant expenses for Buenaventura during the 2007-2008 two-year transition period, which also impacted the income tax payable by Buenaventura for said fiscal years. However, the modified pricing structure also favorably impacted Buenaventura’s financial results with a corresponding increase in Buenaventura’s income tax payment to SUNAT.

SUNAT’s position is that Buenaventura should disregard the additional expenses incurred in connection with the shift to variable price arrangement for purposes of calculating its income tax for fiscal years 2007 and 2008. According to SUNAT, said payments correspond to an early settlement of financial derivative contracts in situations where the Company did not establish the purpose or risks covered by such instruments. Additionally, SUNAT does not recognize the tax losses which the Company offset during fiscal years 2009 and 2010, related to the losses incurred during fiscal years 2007 and 2008.

146

The claim for the years 2007, 2008, 2009 and 2010 initially amounted to 373.3 million soles (approximately US$103.7 million) which, according to SUNAT’s estimations, amounted to 2,107.5 million soles (approximately US$585.4 million) including penalties and accrued interest as of the date of commencement of the collection proceedings.

On November 26, 2020, following the intervening tax court’s decision to dismiss the Company’s appeal against certain Administrative Resolutions issued by SUNAT in connection with the above-referenced matter, SUNAT began collection proceedings in respect of such amounts. Following the commencement of such collection proceedings by SUNAT, the Company filed a request for deferral and payment plan of the amounts claimed by SUNAT in order to make such tax payments over a 67-month term, in addition to making interest payments in connection with such payments. The requested payment plan consists of an initial payment in an amount equal to 14% of the amount claimed by SUNAT and 66 equal installments for the remaining amounts. In order to finalize the deferral and payment agreement with SUNAT, the Company was required to deliver Letters of Credit in an amount equal to the aggregate claimed amount in accordance with applicable law. To satisfy this requirement, on December 30, 2020, the Company entered into the Syndicated L/C Agreement with a group of financial entities and following delivery of the Letters of Credit, SUNAT approved the Company’s payment plan.

On July 30, 2021, the Company paid the full amount of the disputed tax assessment related to the 2007, 2008, 2009 and 2010 tax processes that were subject to deferment and installment and that are recorded in the caption “Trade and other receivables, net”, For the fiscal years 2007 and 2008, the total amount paid was S/1,584,227,000 (equivalent to US$398,548,000), which included updating the debt to reflect interest accrued as of July 30, 2021, such interest amounting to S/78,279,000 (equivalent to US$19,693,000). For the fiscal year 2009, total amount paid was S/193,398,000 (equivalent to US$48,654,000) which included updating the amount claimed to reflect interest accrued as of July 30, 2021, such interest amounting to S/8,477,000 (equivalent to US$2,133,000). For the fiscal year 2010, which was subject to deferral and installment, the total amount paid was S/356,691,000 (equivalent to US$89,733,000) which included the updating the amount claimed to reflect interest accrued as of July 30, 2021, such interest amounting to S/16,762,000 (equivalent to US$4,217,000).

As of December 31, 2021, as a result of the advance payment mentioned above, the deferral and installment resolutions of the SUNAT tax claim have been rendered null and the letters of credit that were delivered as collateral for said disputed payments have been returned to the issuing banks.

We will continue to pursue appeals on this matter in Peruvian courts. These legal proceedings may be costly and time consuming and there can be no guarantee in respect of the final outcome of these proceedings or that SUNAT will not bring future claims against us.

See Note 29 (d) to the Consolidated Financial Statements for additional information.

Dividends and Dividend Policy

We can distribute three kinds of dividends: (i) cash dividends, which are paid out of our net distributable income for each year, (ii) stock dividends that are akin to stock splits rather than distributions of earnings, which are issued for the purpose of adjusting the book value per share of our stock and (iii) stock dividends for the purpose of capitalizing profits, in each case as described in more detail below. All shares outstanding and fully paid are entitled to share equally in any dividend declared based on the portion of our capital represented by such share. No cash dividend may be declared if our financial statements do not show distributable profits. However, we may declare dividends during the year. We may make interim provisional payments to shareholders in respect of net distributable income for the current fiscal year, which are referred to as “provisional dividends” or “dividends on account” as explained below, provided the financial statements as of end of the month preceding the date where such dividends are declared, show the existence of net distributable income obtained during the current year and there are no losses to be covered from past years.

The Board, following the end of each fiscal year, makes a recommendation at the Annual Mandatory Meeting regarding the amount and timing of payments, if any, to be made as dividends on our Common Shares and Investment Shares. The Shareholders Meeting can delegate to the Board the approval to pay interim dividends.

147

The dividend policy establishes that Buenaventura will distribute an annual cash dividend of at least 20% of net income generated by majority-owned operations and subsidiaries. In the case of Buenaventura’s Associates (Coimolache, and Cerro Verde ), 20% attributable to Buenaventura’s net income will be included if they distribute cash dividends to Buenaventura. In principle there are two kinds of dividend payments: interim dividends, which are approved by the Board and are generally paid during the fourth quarter of the year, and the final dividend payment, which will be paid in accordance with the general shareholders’ meeting resolutions. However, the amount and timing of such payments is subject to the final approval at such Annual Mandatory Meeting and Board meeting, as well as to the availability of earnings to distribute. According to the Peruvian Companies Law, holders of at least 20% of the total Common Shares outstanding can request a dividend of 50% or less of the previous year’s after-tax profits, net of amounts allocated to the legal reserve.

Available earnings are subject to the following priorities. First, the mandatory employee profit sharing of 8% of pre-tax profits (which may differ from pre-tax profits determined under IFRS due to different depreciation treatment and different adjustments of non-taxable income and/or non-deductible expenses) is paid.

Next, remaining earnings are taxed at the standard corporate income tax rate, which is 29.50%. Not less than 10% of such after-tax net profits must then be allocated to a legal reserve, which is not available thereafter except to cover future losses or for use in future capitalizations, in which case it must be replenished again. Amounts reserved are nevertheless included in taxable income. The obligation to fund this reserve continues until the reserve constitutes 20% of the paid-in share capital. In addition, the holders of Common Shares can agree to allocate any portion of the net profits to any special reserve. The remainder of the net profits is available for distribution to shareholders.

Dividends are subject to an additional withholding tax for shareholders that are either (i) individuals, whether domiciled or non-domiciled in Peru, or (ii) non-domiciled companies or entities. For dividends paid out of our accumulated net profits, the withholding tax rate is 5% when the dividend originated from profits earned on or after January 1, 2017. If any tax or other governmental charge will become payable by Scotiabank Peru, as custodian, the Depositary or us with respect to any ADR or any deposited securities represented by the ADSs evidenced by such ADR, such tax or other governmental charge will be payable by the owner or beneficial owner of such ADR to the Depositary.

Dividends paid to domiciled companies or entities are not subject to such withholding tax. If any tax or other governmental charge will become payable by Scotiabank Peru, as custodian, the Depositary or us with respect to any ADR or any deposited securities represented by the ADSs evidenced by such ADR, such tax or other governmental charge will be payable by the owner or beneficial owner of such ADR to the Depositary.

Dividends on issued and outstanding Common Shares and Investment Shares are distributed in accordance with the proportion of the total capital represented by such respective shares. Dividends are distributed pro rata in accordance with the number of Common Shares or Investment Shares. Accordingly, any dividend declared would be apportioned 99.73% to the holders of Common Shares and 0.27% to the holders of Investment Shares. This proportion will not change in the future except if, and to the extent that holders of Common Shares and Investment Shares exercise their preemptive rights disproportionately in any future issuance of Common Shares and Investment Shares, or if we issue Common Shares without preemptive rights in accordance with Article 259 of the Peruvian Companies Law.

Holders of Common Shares and Investment Shares are not entitled to interest on dividend payments.

Holders of ADRs are entitled to receive dividends with respect to the Common Shares underlying the ADSs evidenced by such ADRs, subject to the terms of the related Amended and Restated Deposit Agreement, to the same extent as owners of Common Shares.

148

To the extent that we declare and pay dividends on the Common Shares, owners of the ADSs on the relevant record date are entitled to receive the dividends payable in respect of the Common Shares underlying the ADSs, subject to the terms of the Amended and Restated Deposit Agreement. Cash dividends are paid to the Depositary in Soles and, except as otherwise described under the Amended and Restated Deposit Agreement, are converted by the Depositary into U.S. Dollars and paid to owners of ADRs net of currency conversion expenses. Under the Amended and Restated Deposit Agreement, the Depositary may, and will if we so request, distribute stock dividends in the form of additional ADRs evidencing whole ADSs resulting from a dividend or free distribution of Common Shares by us received by the Depositary. Amounts distributed with respect to ADSs were subject to a Peruvian withholding income tax of 6.8% for profits earned during 2016, which was the withholding tax rate applicable to distributions in respect of Common Shares during 2016. The withholding tax rate decreased to 5% for dividends paid out of our accumulated net profits after December 31, 2016. See “Item 10. Additional Information—E. Taxation—Peruvian Tax Considerations.”

We issue stock dividends for value per share of our stock. The book value of our share capital is based on the nominal (par) value of each share but is adjusted to account for inflation; thus, in inflationary periods, our book value will increase while the nominal value will remain constant. To adjust the book value of each share to equal or approximate the nominal value, we periodically issue new shares that are distributed as stock dividends to each existing shareholder in proportion to such shareholder’s existing holdings, unless it increases the nominal value of the existing shares. These stock dividends (which under the Peruvian income tax law are not considered dividends) do not change a stockholder’s percentage of interest in us. In addition, we may from time to time capitalize profits and, in such case, must distribute stock dividends representing the profits capitalized.

Dividends not collected within 10 years will be retained by us, increasing our legal reserve, and the right to collect such dividends will expire.

Under Peruvian law, each company may make formal cash distributions only out of net distributable income (calculated on an individual, unconsolidated basis and demonstrated by a statement of financial position at any given time). We, however, may pay provisional dividends. Payment of provisional dividends will be approved on the basis of consolidated financial statements which show the existence of net distributable income obtained during the current fiscal year. If, following such an interim provisional payment, we suffer a loss or if we finish the fiscal year with a net income that is lower than the amount of provisional dividends paid during such fiscal year, shareholders that acted in good faith may retain the dividends exceeding the distributable profit, with such dividends counting as advanced payments credited against profits or liquidation proceeds that they are entitled to receive in following periods. Therefore, it has been and continues to be our policy not to require shareholders to return such payment of provisional dividends, but rather to cover such contingency through a “dividends paid in advance” account to be offset by future net distributable income.

The following table sets forth the amounts of interim and final cash dividends and the aggregate of cash dividends paid with respect to the years 2018 to 2021. Dividends with respect to the years 2018 to 2021 were paid per Common Share and ADS.

Non-controlling Shareholders

Law No. 28370, published on October 30, 2004, included in the Peruvian Companies Law certain provisions for the protection of non-controlling shareholders of public companies that are sociedades anónimas abiertas such as us and that were formerly contained in Law No. 26985, which was abrogated. Legislative Decree No. 1061, effective since June 29, 2008, Law No. 29782, effective since July 29, 2011, and most recently Law No. 30050, effective since June 27, 2013, have abrogated or amended certain of these provisions. Pursuant to Article 262-A of the Peruvian Companies Law, we will furnish on our website and on the SMV’s website, upon the earlier to occur of (1) sixty days after the Annual Mandatory Meeting, or (2) the expiration of the three-month period after the end of the prior fiscal year in which such Annual Mandatory Meeting is required to be held, the information regarding total number and value of any shares not claimed by shareholders, the name of such shareholders, the share quote in the securities market for such shares, the total amount of uncollected dividends, the name of shareholders having uncollected dividends and where shares and dividends pending claim are available for the non-controlling shareholders. Article 262-B describes the procedure to request share certificates and/or dividends, that the holder of the shares can instruct us to deposit the dividends in a specific bank account, and that delivery of such share certificates and/or dividends is to be made within 30 days from the request. Article 262-F describes the procedure for handling any claim that the non-controlling shareholders may file, such claims to be resolved by the SMV. SMV may apply warnings and fines between approximately US$ 1,300 and US$32,500 in case the Company fails to comply such provisions for the protection of non-controlling shareholders.

Additionally, the par value per share (for both Common Shares and Investment Shares) is S/.10.

B. Memorandum and Articles of Association

Organization and Register

We were formed on September 7, 1953 by public deed as a Peruvian sociedad anónima. However, in May of 1998, our By-laws were changed to conform with the new Peruvian Companies Law. The term of existence is indefinite and our principal place of business is Lima, Peru. We are registered under file number 02136988 at the Companies Registry of Lima.

We are managed by the Board and the management.

Objectives and Purposes

Our legal purpose, as set forth in our Articles of Association and By-laws, is to engage in mining operations and related activities either directly or through majority-owned subsidiaries and controlled companies. Likewise, we may hold shares of other companies, including companies performing mining operations.

Directors

The Board, which must be composed of seven members, is elected for a three-year term at the Annual Mandatory Meeting. Any changes in the Board require the approval of the shareholders. The removal of the Board must be approved at a shareholders’ meeting, attended by holders of 75% of the Common Shares in the first summons and 70% of the Common Shares in the second summons, by resolution approved by at least two thirds of the total number of Common Shares outstanding. In the case of resignation of directors, the Board may appoint substitute directors who will serve until the next shareholders’ meeting.

152

Members of the Board (“Directors”) are elected for a term of three years and may be reelected indefinitely. Pursuant to Article 29 of our By-laws, Directors are not required to be shareholders. The Board, in its first meeting after the Annual Mandatory Meeting during which elections are held, must choose from among its members a Chairman and a Lead Director. The Peruvian Companies Law requires that all companies (sociedades anónimas) provide for the representation of non-controlling shareholders on their Boards of Directors. To that effect, each of our Common Shares gives the holder the right to as many votes as there are directors to be elected. Each holder may pool his votes in favor of one person or distribute them among various persons. Those candidates for the Board who receive the most votes are elected directors.

The Board of Directors meets when called by the Chairman of the Board, who is appointed by the Board. The Board of Directors is validly convened when all Directors are present and unanimously agree to carry out the meeting for the purpose of transacting the business that has been proposed. Pursuant to Article 177 of the Peruvian Companies Law, Directors may be jointly and severally liable to us, the shareholders and third parties for their actions if they act with willful misconduct, gross negligence, or abuse their powers. In addition, Article 3 of Law No. 29720, which has been in force since June 26, 2011, as amended by Law No. 30050 in force since June 27, 2013, provides that directors and managers are liable for economic damages or any other kind of damages caused to us by any transaction they have approved that favors such director’s, or a related party’s, interest instead of the Company’s, when: (i) one of the parties involved in the transaction is a company whose shares are listed in the local stock exchange, as in our case; (ii) the shareholder controlling such listed company also controls the other party involved in the transaction; and (iii) the transaction is not made under arm’s-length conditions and represents at least 10% of such company’s assets. Directors not participating in the Board meeting or that voted against the transaction are not liable.

In addition, Article 51 of the Securities Market Law contains additional prohibitions for directors and managers of companies whose shares are traded in the stock exchange. Pursuant to Article 51(a) of such law, directors and managers are forbidden to receive loans from listed companies and from using goods and services of the listed company without the Board’s authorization for their own use, in their own profit or to benefit persons related to the directors and managers. Additionally, subsection (b) thereof further provides that directors and managers are forbidden from using their positions to obtain improper benefits for them or for persons related to them.

In connection therewith, Article 180 of the Peruvian Companies Law provides that directors can neither approve of resolutions that do not protect the company’s interest but rather the director’s own interests or a related party’s interest, nor may a director use a business opportunity that the director is aware of due to their position as a director in their own interest or in a related party’s interest. Our By-laws do not contain any provisions related to a director’s power to vote on matters in which the director is materially interested. However, such Article 180 of the Peruvian Companies Law requires a director with an interest that conflicts with an interest of ours on a specific matter to disclose such interest to us and abstain from participating in the deliberation and decision of the said matter. A director that contravenes such requirement is liable for the damages suffered by us and can be removed by the Board or a shareholders’ meeting upon the request of any shareholder or any member of the Board.

Our By-laws also do not contain any provisions with respect to the power of the directors to vote upon matters relating to their own compensation. Nevertheless, Article 30 of the By-laws requires that the Board receive compensation of no more than 4% of the profits of each fiscal year after making deductions for workers’ profit sharing, taxes, reinvestment of profits for tax benefits and legal reserves. This amount will be submitted for ratification by the General Meeting during the Annual Mandatory Meeting, at which time it approves the statement of financial position, taxes, reinvestment of profits for tax benefits and legal reserves.

Our By-laws contain no provision relating to the directors’ power to borrow from us. However, Article 179 of the Peruvian Companies Law provides that directors of a company may enter into an agreement with such company only if the agreement relates to operations the Company performs in the regular course of business and in an arms-length transaction. Furthermore, a company may provide a loan to a director or grant securities in his favor only in connection with operations that the Company usually performs with third parties. Agreements, credits, loans or guarantees that do not meet the requirements set forth above require prior approval from at least two thirds of the members of the Company’s Board. Directors are jointly liable to the Company and the Company’s creditors for contracts, credit, loans or securities executed or granted without complying with Article 179 of the Peruvian Companies Law. In addition, as mentioned above, Article 3 of Law No. 29720, as amended, provides that directors and managers are liable for economic or other damages that they may cause because of the approval of resolutions that favor such director’s, or a related party’s, interest instead of the Company’s, when: (i) one of the parties involved in the transaction is a company whose shares are listed in the local stock exchange, as in our case; (ii) the shareholder controlling such listed company also controls the other party involved in the transaction; and (iii) the transaction is not made under arm’s-length conditions and represents at least 10% of such Company’s assets.

Neither our By-laws nor the Peruvian Companies Law contain age limit requirements for the retirement or non-retirement of directors.

Shares and Voting Rights

We have two classes of shares, the Common Shares and the Investment Shares. The Common Shares represent 100% of our outstanding share capital. The Investment Shares have no voting rights and are not, under Peruvian law and accounting rules, characterized as share capital. The Common Shares and the Investment Shares may be either physical share certificates in registered form or book-entry securities in the CAVALI ICLV S.A. book-entry settlement system, also in registered form.

Holders of Common Shares are entitled to one vote per share, with the exception of the election of the Board, where each such holder is entitled to one vote per share per nominee. Each holder’s votes may all be cast for a single nominee or they may be distributed among the nominees at the holder’s discretion. Holders of Common Shares may attend and vote at shareholders’ meetings either in person or through a proxy. Additionally, holders of Common Shares have the right to participate in the distribution of dividends and shareholder equity resulting from liquidation. Our By-laws do not establish a maximum time limit for the payment of the dividends. However, according to Article 232 of the Peruvian Companies Law, the right to collect past-due dividends in the case of sociedades anónimas abiertas, as we are, expires at 10 years from the date on which the payment was due in accordance with the dividend declaration.

Our share capital may be increased by holders of Common Shares at a shareholders’ meeting. Capital reductions may be voluntary or mandatory and must be approved by holders of Common Shares at a shareholders’ meeting. Capital reductions are mandatory when accumulated losses exceed 50% of capital to the extent such accumulated losses are not offset by accumulated earnings and capital increases within the following fiscal year. Capital increases and reductions must be communicated to the SMV, the Lima Stock Exchange and the SUNAT and published in the official gazette El Peruano and in a widely circulated newspaper in the city in which we are located.

The Investment Shares do not represent our stock obligations. Holders of Investment Shares are neither entitled to exercise voting rights nor to participate in shareholders’ meetings. However, Investment Shares confer upon the holders thereof the right to participate in the dividends distributed according to their nominal value, in the same manner as Common Shares, as well as to participate in increases of the Investment Shares account.

Changes in the Rights of Shareholders

Our By-laws do not contain special provisions relating to actions necessary to change the rights of holders of the classes of shares. However, Article 88 of the Peruvian Companies Law establishes that all shares of a same class must have the same rights and obligations, and that if we decide to establish different rights and obligations, we must create a different class of shares, which creation will be agreed upon by the General Meeting in accordance with the requirements for modification of the By-laws. The Common Shares are the only class of shares representing 100% of our share capital, and, therefore, each Common Share has the same rights and obligations of each other Common Share. These requirements are described under “—Shares and Voting Rights” above.

The rights of any class of shares may not be reduced, except in accordance with the Peruvian Companies Law.

154

Shareholders’ Meetings

Pursuant to Peruvian law and our By-laws, the Annual Mandatory Meeting must be held during the three-month period after the end of each fiscal year. Additional General Meetings may be held during the year. Because we are a sociedad anónima abierta (publicly held corporation), we are subject to the special control of the SMV, as provided in Article 253 of the Peruvian Companies Law, to determine whether we have incurred any breach of the Peruvian Companies Law or regulations of the SMV and to impose sanctions. Shareholders’ meetings are convened by the Board when deemed convenient for us or when it is requested by the holders of at least 5% of the Common Shares, provided that such Common Shares do not have their voting rights suspended. If, at the request of holders of at least 5% of the Common Shares, the shareholders’ meeting is not convened by the Board within 15 business days of the receipt of such request, such holders of at least 5% of the Common Shares may request a notary public or a judge to convene the meeting. The Board is deemed to have implicitly refused to convene the meeting if the Board (a) does not convene a shareholders’ meeting within 15 business days of receipt of the request, (b) suspends or amends the terms of the agenda or in any other way amend the terms of the summons already made upon the request of at least 5% of the Common Shares or (c) schedules the shareholders’ meeting more than 40 days after the date on which the summons is published. The notary public or the judge of the domicile of the Company shall call for the shareholders meeting. Resolución CONASEV No. 111-2003-EF-94.10, as amended by Resolución CONASEV No. 078-2010-EF/94.01.1, approved provisions related to the right of the non-controlling shareholders to obtain information regarding a sociedad anónima abierta (publicly held corporation) such as ourselves. Notwithstanding the notice requirements as described in the preceding two sentences, any shareholders’ meeting will be deemed called and legally commenced, provided that the shareholders representing all of the voting shares are present, and provided that every present shareholder, whether or not such shareholder has paid the full price of such shareholder’s shares, agrees to hold the shareholders’ meeting and accepts the business to be discussed therein. Holders of Investment Shares have no right to request the Board to convene shareholders’ meetings.

Since we are a sociedad anónima abierta (publicly held corporation), notice of shareholders’ meetings must be given by publication of a notice, with the publication occurring at least 25 days before any shareholders’ meeting, in El Peruano and in a widely circulated newspaper in the city in which we are located. The notice requirement may be waived at the shareholders’ meeting by holders of 100% of the outstanding Common Shares. According to Article 25 of our By-laws and Article 257 of the Peruvian Companies Law, shareholders’ meetings called for the purpose of considering a capital increase or decrease, the issuance of obligations, a change in our By-laws, the sale in a single act of assets with an accounting value that exceeds 50% of our capital stock, a merger, division, reorganization, transformation or dissolution, are subject to a first, second and third quorum call, each of the second and third quorum to occur upon the failure of the preceding one. A quorum for the first call requires the presence of shareholders holding 50% of our total voting shares. For the second call, the presence of shareholders holding at least 25% of our total voting shares constitutes a quorum, and for the third call there is no quorum requirement. These decisions require the approval of the majority of the voting shares represented at the shareholders’ meeting. General Meetings convened to consider all other matters are subject to a first and second quorum call, the second quorum call to occur upon the failure of the first quorum.

In the case of shareholders’ meetings called for the purpose of considering the removal of members of the Board, at least 75% and 70% of the total number of Common Shares outstanding are required to be represented at the shareholders’ meeting on the first quorum call and second quorum call. Provided such quorum is attained, the affirmative vote of no less than two thirds of the total number of Common Shares outstanding is required to effect the removal of members of the Board. The special quorum and voting requirements described above cannot be modified at a shareholders’ meeting called for the purpose of considering the removal of members of the Board.

Under our By-laws, the following actions are to be taken at the Annual Mandatory Meeting of shareholders: approval of our statements of financial position, profit and loss statements and annual reports; the approval of management performance; the allocation of profits; the election of external auditors; the election of the members of the Board; and any other matters submitted by the Board. The following actions are to be taken at the same annual shareholders’ meetings if the quorum and majority requirements are met or at any other shareholders’ meeting: any amendment of our By-laws; any decision to increase or reduce capital; any decision to issue debt; initiating investigations or requesting auditor’s reports; and liquidating, spinning-off, merging, consolidating, dissolving, or changing our business form or structure.

In accordance with Article 21 of the By-laws, only those holders of Common Shares whose names are inscribed in our share register not less than 10 days in advance of a meeting will be entitled to attend shareholders’ meetings and to exercise their rights.

155

In response to the COVID-19 pandemic, article 5 of Urgency Decree 056-2020 (published on May 15, 2020) and article 4 of Urgency Decree 018-2021 (published on February 11, 2021) authorized companies listed in the Lima Stock Exchange, as we are, to convene and hold virtual shareholders’ meetings during a state of national emergency using technological or telematic means, even if the by-laws of such companies only contemplated physical or face-to-face meetings. Based on such Urgency Decrees, SMV issued several regulations including Regulation No. SMV 050-2020-SMV-02 and Regulation No. 019-2021-SMV-02 establishing how to convene such virtual meetings, measures to allow the shareholders to participate and vote, and several other related matters. On the grounds of such provisions, we held virtually our 2020 Annual Mandatory Meeting approving our financial statements for year 2019 and our 2021 Annual Mandatory Meeting approving our financial statements for year 2020. Finally, on May 15, 2021 Law N° 31194 was enacted amending Article 21-A of the Peruvian Companies Law. The newly-enacted Article 21-A provides that shareholders meetings as well as board meetings may be held virtually through electronic or similar means provided that the by-laws contemplate virtual meetings, whether a state of national emergency exists or not. Second Supplementary Final Provision Law N° 31194 stated that during a state of national emergency where certain constitutional rights are suspended, shareholders’ meetings and board meetings can be held virtually even if the by-laws of the company do not contemplate such virtual meetings. Our 2022 Annual Mandatory Meeting shall be held virtually as, on the date such meeting was announced, the state of national emergency imposed by Supreme Decree N° 016-2022-PCM was in effect.

Limitations on the Rights of Nonresident or Foreign Shareholders

There are no limitations in our By-laws or the Peruvian Companies Law on the rights of nonresident or foreign shareholders to own securities or exercise voting rights on our securities.

Change in Control

There are no provisions in our By-laws that would have the effect of delaying, deferring or preventing a change in control.

Disclosure of Share Holdings

There are no provisions in our By-laws governing the ownership threshold above which share ownership must be disclosed. However, according to Regulation No. 009-2006-EF.94.10 of the SMV, which became effective on May 3, 2006, as amended by Regulation No. 020-2006-EF.94.10, Regulation No. 05-2009-EF-94.01.1 and Regulation No. 034-2025-SMV-01.of the SMV, when, an individual or financial group acquires, in one act or various successive acts, a significant percentage (more than 25%) of the voting shares of a company with shares listed in a stock exchange, as well as upon any person or group increasing its ownership above the 50% and 60% thresholds, a procedure known as Oferta Pública de Adquisición, or a “Takeover Bid,” must be followed. This has the effect of alerting other shareholders and the market that an individual or financial group has acquired a significant percentage of a company’s voting shares, and gives other shareholders the opportunity to sell their shares at the price offered by the purchaser. The purchaser is obliged to launch a Takeover Bid unless it is exempt pursuant to Regulation No. 009-2006-EF.94.10 of the SMV, as amended. The purchase of ADRs is exempted from the Takeover Bid unless the holders: (i) exercises the voting rights of the Common Shares underlying the ADSs evidenced by such ADRs, or (ii) requests the delivery of such underlying Common Shares. In addition, the SMV and the Lima Stock Exchange must be notified of any transfer of more than 5% of our paid-in capital.

Changes in Capital

Our By-laws do not establish special conditions for increases or reductions of capital that are more stringent than required by the Peruvian Companies Law. Furthermore, the Peruvian Companies Law forbids sociedades anónimas abiertas, such as us, from including in their By-laws stipulations limiting the transfer of their shares or restraining their trading in other ways. We cannot recognize a shareholders’ agreement that contemplates limitations, restrictions or preferential rights on the transfer of shares, even if such agreement is recorded in our share register (matrícula de acciones) or in CAVALI ICLV S.A., unless they refer to shares that are not listed in a stock exchange, which is not the case for our shares.

156

Economic Group

On January 1, 2017 new Regulations on Indirect Property, Relation and Economic Groups (Reglamento de Propiedad Indirecta, Vinculación y Grupos Económicos) (the “Regulations”) approved by Regulation No. 019-2015-SMV-01 became effective, replacing the prior Regulations that were in effect since 2006. The new Regulations, which have been amended by Regulations 048-2016-SMV-01, 013-2017-SMV-01, 026-2017-SMV-01 and 016-2019-SMV-01, define more precisely who are considered independent directors, increase the standards of information we are required to provide, require us to identify the individuals that control our economic group, require us to report related individuals and entities; reduce the number of shareholders required to determine that there exists a “representative participation” from 10% of the total capital stock to 4% of voting shares and extend the definition of control. The “representative participation” definition is mainly used by listed companies such as us to determine the existence of indirect property. Regulation No. 083-2016-SMV-01 approved the new forms to be used to provide the SMV all the information about our economic group.

Criminal liability of companies

On April 2016, Law No. 30424 was enacted to establish the administrative liability of legal entities, such as us, in connection with transnational active bribery. The law has been amended by Legislative Decree No. 1352, which was published on January 7, 2017 and became effective on January 1, 2018 and Law No. 30835 in force since August 3, 2018. Regulations to this law have been recently approved by Supreme Decree No. 002-2019-JUS. The amendment expanded the definition of bribery beyond transnational active bribery to include asset laundering, illegal mining and organized crime. The law provides rules to be followed in case of a merger or spin-off and states that a legal entity is administratively liable for the above crimes when they have been committed in its name or for its benefit by its shareholders, directors, managers or employees that are subject to the control and authority of the legal entity. Several sanctions can be imposed on a company as result of such crimes, including fines, prohibitions on performing certain activities, cancellation of permits and even dissolution. A legal entity is not liable if its shareholders, directors, managers or employees engage in bribery or related crimes solely for their own benefit or for the benefit of third parties other than the legal entity. The Company will be exempted from any liability for such crimes if it adopts within its organization, and before the crime is committed, a so-called prevention model consistent with the Company’s nature, risks, necessities and characteristics, consisting of control, monitoring and surveillance measures suitable to prevent such crimes. Such model includes the appointment by the Board of a person in charge of prevention that must perform autonomously. In order to file a criminal accusation against the Company, a technical report from the SMV that analyzes the prevention model is required. We have prepared the prevention model required under Law No. 30424, as amended, following the guidelines approved by Regulation No. 006-2021-SMV-01, in addition to the other compliance measures and policies we currently have. The regulations contain, among other provisions, several definitions, types of risks and the criteria to identify them, as well as the minimum elements a prevention model must contain.

Dividends and Dividend Policy

We can distribute three kinds of dividends: (i) cash dividends, which are paid out of our net distributable income for each year, (ii) stock dividends that are akin to stock splits rather than distributions of earnings, which are issued for the purpose of adjusting the book value per share of our stock and (iii) stock dividends for the purpose of capitalizing profits. All shares outstanding and fully paid are entitled to share equally in any dividend declared based on the portion of our capital represented by such share. No cash dividend may be declared if our financial statements do not show distributable profits. We may declare dividends during the year. Also, we may make interim provisional payments to shareholders in respect of net distributable income for the current fiscal year, which are referred to as “provisional dividends” or “dividends on account” as explained below, provided the financial statements as of end of the month preceding the date where such dividends are declared, show the existence of net distributable income obtained during the current year and there are no losses to be covered from past years.

The Board, following the end of each fiscal year, makes a recommendation at the Annual Mandatory Meeting regarding the amount and timing of payments, if any, to be made as dividends on our Common Shares and Investment Shares. The Shareholders Meeting can delegate to the Board the approval to pay interim dividends and, at our Shareholders Meeting such authorization was granted to our Board by the participants in the Shareholders Meeting.

157

The dividend policy establishes that Buenaventura will distribute an annual cash dividend of at least 20% of net income generated by majority-owned operations and subsidiaries. In the case of Buenaventura’s Associates (Coimolache and Cerro Verde), 20% of attributable to Buenaventura’s net income will be included if they distribute cash dividends to Buenaventura. In principle there are two kinds of dividend payments: interim dividends, which are approved by the Board and are generally paid during the fourth quarter of the year, and the final dividend payment, which will be paid in accordance with the general shareholders’ meeting resolutions. However, the amount and timing of such payments is subject to the final approval at such Annual Mandatory Meeting and Board meeting, as well as to the availability of earnings to distribute. According to the Peruvian Companies Law, holders of at least 20% of the total Common Shares outstanding can request a dividend of 50% or less of the previous year’s after-tax profits, net of amounts allocated to the legal reserve.

Available earnings are subject to the following priorities. First, the mandatory employee profit sharing of 8% of pre-tax profits (which may differ from pre-tax profits determined under IFRS due to different depreciation treatment and different adjustments of non-taxable income and/or non-deductible expenses) is paid.

Next, remaining earnings are taxed at the standard corporate income tax rate, which is 29.50%. Not less than 10% of such after-tax net profits must then be allocated to a legal reserve, which is not available thereafter except to cover future losses or for use in future capitalizations, in which case it must be replenished again. Amounts reserved are nevertheless included in taxable income. The obligation to fund this reserve continues until the reserve constitutes 20% of the paid-in share capital. In addition, the holders of Common Shares can agree to allocate any portion of the net profits to any special reserve. The remainder of the net profits is available for distribution to shareholders.

Dividends are subject to an additional withholding tax for shareholders that are either (i) individuals, whether domiciled or non-domiciled in Peru, or (ii) non-domiciled companies or entities. For dividends paid out of our accumulated net profits, the withholding tax rate is 5%, when the dividend originated from profits earned on or after January 1, 2017. If any tax or other governmental charge will become payable by Scotiabank Peru, as custodian, the Depositary or us with respect to any ADR or any deposited securities represented by the ADSs evidenced by such ADR, such tax or other governmental charge will be payable by the owner or beneficial owner of such ADR to the Depositary.

Dividends paid to domiciled companies or entities are not subject to such withholding tax. If any tax or other governmental charge will become payable by Scotiabank Peru, as custodian, the Depositary or us with respect to any ADR or any deposited securities represented by the ADSs evidenced by such ADR, such tax or other governmental charge will be payable by the owner or beneficial owner of such ADR to the Depositary.

Dividends on issued and outstanding Common Shares and Investment Shares are distributed in accordance with the proportion of the total capital represented by such respective shares. Dividends are distributed pro rata in accordance with the number of Common Shares or Investment Shares. Accordingly, any dividend declared would be apportioned 99.73% to the holders of Common Shares and 0.27% to the holders of Investment Shares. This proportion will not change in the future except and to the extent that holders of Common Shares and Investment Shares exercise their preemptive rights disproportionately in any future issuance of Common Shares and Investment Shares, or if we issue Common Shares without preemptive rights in accordance with Article 259 of the Peruvian Companies Law.

Holders of Common Shares and Investment Shares are not entitled to interest on dividend payments.

Holders of ADRs are entitled to receive dividends with respect to the Common Shares underlying the ADSs evidenced by such ADRs, subject to the terms of the related Amended and Restated Deposit Agreement, to the same extent as owners of Common Shares.

158

To the extent that we declare and pay dividends on the Common Shares, owners of the ADSs on the relevant record date are entitled to receive the dividends payable in respect of the Common Shares underlying the ADSs, subject to the terms of the Amended and Restated Deposit Agreement. Cash dividends are paid to the Depositary in Soles and, except as otherwise described under the Amended and Restated Deposit Agreement, are converted by the Depositary into U.S. Dollars and paid to owners of ADRs net of currency conversion expenses. Under the Amended and Restated Deposit Agreement, the Depositary may, and will if we so request, distribute stock dividends in the form of additional ADRs evidencing whole ADSs resulting from a dividend or free distribution of Common Shares by us received by the Depositary. Amounts distributed with respect to ADSs were subject to a Peruvian withholding income tax of 6.8% for profits earned during 2016, which was the withholding tax rate applicable to distributions in respect of Common Shares during 2016. The withholding tax rate decreased to 5% for dividends paid out of our accumulated net profits after December 31, 2016. See Item 10. “Additional Information—E. Taxation—Peruvian Tax Considerations.”

We issue stock dividends for value per share of our stock. The book value of our share capital is based on the nominal (par) value of each share but is adjusted to account for inflation; thus, in inflationary periods, our book value will increase while the nominal value will remain constant. To adjust the book value of each share to equal or approximate the nominal value, we periodically issue new shares that are distributed as stock dividends to each existing shareholder in proportion to such shareholder’s existing holdings, unless it increases the nominal value of the existing shares. These stock dividends (which under the Peruvian income tax law are not considered dividends) do not change a stockholder’s percentage of interest in us. In addition, we may from time to time capitalize profits and, in such case, we have to distribute stock dividends representing the profits capitalized.

Dividends not collected within 10 years will be retained by us, increasing our legal reserve, and the right to collect such dividends will expire.

Under Peruvian law, each company may make formal cash distributions only out of net distributable income (calculated on an individual, unconsolidated basis and demonstrated by a statement of financial position at any given time). We, however, may pay interim provisional dividends as explained above. If, following such an interim provisional payment, we suffer a loss or if we finish the fiscal year with a net income that is lower than the amount of provisional dividends paid during such fiscal year, shareholders that acted in good faith may retain the dividends exceeding the distributable profit, with such dividends counting as advanced payments credited against profits or liquidation proceeds that they are entitled to receive in following periods. Therefore, it has been and continues to be our policy not to require shareholders to return such payment of provisional dividends, but rather to cover such contingency through a “dividends paid in advance” account to be offset by future net distributable income.

Non-controlling Shareholders

Law No. 28370, published on October 30, 2004, included in the Peruvian Companies Law certain provisions for the protection of non-controlling shareholders of public companies that are sociedades anónimas abiertas, such as us, and that were formerly contained in Law No. 26985, which was abrogated. Legislative Decree No. 1061, effective since June 29, 2008, Law No. 29782, effective since July 29, 2011, and most recently Law No. 30050, effective since June 27, 2013, have abrogated or amended certain of these provisions. Pursuant to Article 262-A of the Peruvian Companies Law, we will furnish on our website and on the SMV’s website, upon the earlier to occur of (1) sixty days after the Annual Mandatory Meeting, or (2) the expiration of the three-month period after the end of the prior fiscal year in which such Annual Mandatory Meeting is required to be held, the information regarding total number and value of any shares not claimed by shareholders, the name of such shareholders, the share quote in the securities market for such shares, the total amount of uncollected dividends, the name of shareholders having uncollected dividends and where shares and dividends pending claim are available for the non-controlling shareholders. Article 262-B describes the procedure to request share certificates and/or dividends, that the holder of the shares can instruct us to deposit the dividends in a specific bank account, and that delivery of such share certificates and/or dividends is to be made within 30 days from the request. Article 262-F describes the procedure for handling any claim that the non-controlling shareholders may file, such claims to be resolved by the SMV. SMV may apply warnings and fines between approximately US$1,235 and US$ 30,800 in case the Company fails to comply such provisions for the protection of minority shareholders.

C. Material Contracts

Below is a description of the material agreements entered into that we have entered into as of December 31, 2021. Such summaries exclude those agreements entered into in the ordinary course of business.

5.50% Senior Notes due 2026

In order to comply with its tax obligations, the Buenaventura’s Shareholders’ Meeting held on May 21, 2021 and its board of directors meeting held on July 12, 2021 approved the issue of senior unsecured notes due 2026 (hereinafter the “Notes”) which were issued on July 23, 2021 with the following terms:

-Denomination of Issue: US$550,000,000 5.500% Senior Notes due 2026.

-Principal Amount: US$550,000,000.

-Issue Date: July 23, 2021.

-Maturity Date: July 23, 2026.

-Issue Price: 99.140% of the principal amount.

-Interest Rate: 5.500% per annum.

-Offering Format: private placement under Rule 144A and Regulation S of the U.S. Securities Act of 1933.

-Listing: The bonds were listed on the SGX-ST

The bonds were offered in a private placement to qualified institutional buyers in accordance with Rule 144A under the Securities Act of 1933, as amended (hereinafter the “Securities Act”), and outside the United States to non-U.S. persons in accordance with Regulation S under the Securities Act. The Notes are fully and unconditionally guaranteed jointly and severally by Compañía Minera Condesa S.A., Inversiones Colquijirca S.A., Procesadora Industrial Río Seco S.A. and Consorcio Energético Huancavelica S.A.

As part of its issuance of the Notes, Buenaventura entered into an indenture (the “Indenture”) among Buenaventura, The Bank of New York Mellon, and various subsidiary guarantors. Under the terms of the Indenture, Buenaventura agreed to comply with certain restrictive covenants. As a result of these covenants, Buenaventura must confirm that it is in compliance with the Notes Indenture if it wants to undertake any of the following transactions that involve:

(i) the incurrence of additional debt;

(ii) certain asset sales;

(iii) the making of certain investments;

(iv) the payment of dividends;

(v) the purchasing of Buenaventura’s equity interests or making any principal payment prior to any scheduled final maturity or schedule repayment of any indebtedness that is subordinated to the Notes (collectively, “Restricted Payments”, as defined in the Indenture),

(vi) creation of liens; or

(vii) a merger, consolidation or sale of substantially all assets.

These covenants are known as “Limitations on incurrence of indebtedness”, “Limitation on Asset Sales”, “Limitation on Restricted Payments”, “Limitation on Liens” and “Limitation on Merger, Consolidation or Sale of Assets”, respectively, which also have exceptions that let the Company operate in the ordinary course of business.

D. Exchange Controls

Since August 1990, there have been no exchange controls in Peru and all foreign exchange transactions are based on free market exchange rates. Before August 1990, the Peruvian foreign exchange market consisted of several alternative exchange rates. Additionally, during the 1990s, the Peruvian currency has experienced a significant number of large devaluations, and Peru has consequently adopted and operated under various exchange rate control practices and exchange rate determination policies, ranging from strict control over exchange rates to market determination of rates. Current Peruvian regulations on foreign investment allow the foreign holders of equity shares of Peruvian companies to receive and repatriate 100% of the cash dividends distributed by such companies. Such investors are allowed to purchase foreign exchange at free market currency rates through any member of the Peruvian banking system and transfer such foreign currency outside Peru without restriction.

E. Taxation

The following summarizes the material Peruvian and U.S. federal income tax consequences under present law of the purchase, ownership and disposition of ADSs or Common Shares. The discussion is not a full description of all tax considerations that may be relevant to a decision to purchase ADSs or Common Shares. In particular, this discussion deals only with holders that hold ADSs or Common Shares as capital assets and that have the U.S. Dollar as their functional currency. The summary does not address the tax treatment of certain investors that may be subject to special tax rules, such as partnerships and other entities classified as partnerships for U.S. federal income tax purposes, banks, dealers and traders in securities or foreign currencies, insurance companies, tax-exempt entities, persons that will hold ADSs or Common Shares as a position in a “straddle” or “conversion transaction” for tax purposes, holders who actually or constructively own 10% or more of our shares by either vote or value, certain taxpayers who file applicable financial statements required to recognize income no later than when the associated revenue is reflected on such financial statements and holders who acquired our ADSs or Common Shares pursuant to the exercise of any employee stock option or otherwise as compensation. This discussion does not address all aspects of U.S. federal income taxation that may be applicable to a U.S. Holder (as defined below), including gift, estate, any U.S. state or local taxes, non-U.S. taxes, other than Peruvian taxes as provided below, the U.S. federal alternative minimum tax or the U.S. Medicare tax on net investment income. There is no tax treaty currently in effect between Peru and the U.S., except for a treaty to exchange tax information. The information to be exchanged is defined in such treaty as any data or declaration that may be relevant or essential to the administration and application of taxes. Accordingly, the discussions below of Peruvian and U.S. tax considerations are based on the domestic law of each of Peru and the U.S. which are subject to change possibly with retroactive effect.

“U.S. Holder” means a beneficial owner of ADSs or Common Shares that is (i) a U.S. citizen or resident, (ii) a domestic corporation, (iii) a trust subject to the control of one or more U.S. persons (as described in Section 7701(a)(30)) of the U.S. Internal Revenue Code of 1986, as amended, (“Code”) and the primary supervision of a U.S. court or that has validly elected to be treated as a U.S. person or (iv) an estate the income of which is subject to U.S. federal income taxation regardless of its source.

If a partnership or other entity taxable as a partnership for U.S. federal income tax purposes holds ADSs or Common Shares, the tax treatment of a partner will generally depend on the status of the partner in such partnership and the activities of the partnership. Partners of partnerships holding ADSs or Common Shares should consult their tax advisors.

Cash dividends paid with respect to Common Shares and amounts distributed with respect to ADSs are subject to Peruvian withholding income tax, at a rate of 5% for dividends paid or to be paid beginning January 1, 2017, when the dividend originated from profits earned on or after January 1, 2017. If the dividend originated from profits earned between January 1, 2015 and December 31, 2016, the withholding income tax rate for the dividend is 6.8%. If the dividend originated from profits earned as of December 31, 2014, the withholding income tax rate for dividends is 4.1%. The dividends distribution is related to prior accumulated results. This regime is applicable on dividends that are paid to shareholders that are: (i) individuals, whether resident or nonresident in Peru or (ii) nonresident entities. As a general rule, the distribution of additional Common Shares representing profits, distribution of shares that differ from the distribution of earnings or profits, as well as the distribution of preemptive rights with respect to Common Shares, which are carried out as part of a pro rata distribution to all shareholders, will not be subject to Peruvian Income Tax or withholding taxes.

Capital Gains

Pursuant to Article 6 of the Income Tax Law (the “ITL”), individuals and entities resident in Peru are subject to Peruvian Income Tax on their worldwide income while nonresident individuals or entities are subject to Peruvian Income Tax on their Peruvian source income only.

Furthermore, the ITL states that income deriving from the disposal of securities issued by Peruvian entities is considered Peruvian source income subject to the Income Tax (as defined below).

161

With respect to this matter, Article 2 of the ITL, as amended by Legislative Decree 945, defines: (i) capital gains as any revenue deriving from the disposal of capital goods; and (ii) capital goods as those whose purpose is not to be traded in the regular course of a business. Moreover, Article 2 of the ITL states that income deriving from the disposal of shares and similar securities is considered a capital gain.

Accordingly, capital gains deriving from the disposal of securities issued by legal entities incorporated in Peru are considered Peruvian-source income subject to Peruvian Income Tax.

Currently, regardless of whether or not the transferor is domiciled in Peru, the ITL establishes that taxable income resulting from the disposal of securities is determined by the difference between the sale price of the securities and its tax basis. However, before December 31, 2009, capital gains resulting from the disposal of ADSs or Common Shares issued by legal entities incorporated in Peru were exempt from Peruvian Income Tax if: (i) in the case of non-regular individuals (i.e., individuals who do not frequently trade securities), the transaction was carried out before December 31, 2009; and (ii) in the case of shareholders other than individuals, the transaction was carried out on the Lima Stock Exchange (floor session) before December 31, 2009.

Effective January 1, 2010, the exemption was repealed and, as such, capital gains resulting from the disposal of ADSs or Common Shares issued by legal entities incorporated in Peru became subject to Peruvian Income Tax, or the “Income Tax.” For non-resident entities or individuals, capital gains will be subject to an Income Tax rate of either 5% or 30%, depending on where the transaction takes place. If the transaction is consummated within Peru, the Income Tax rate is 5%; if the transaction is consummated outside of Peru, capital gains are taxed at a rate of 30%.

The ITL Regulations have defined transactions consummated within Peru to mean that the securities at issue are transferred through the Lima Stock Exchange. In contrast, the transaction is considered to have been consummated abroad when (i) the securities at issue are not registered on the Lima Stock Exchange or (ii) registered securities are not transferred through the Lima Stock Exchange.

Before December 31, 2012, for nonresident individuals, the first five tax units (approximately US$6,800) of capital gains deriving from the transfer of securities were exempted from the Income Tax. Effective January 1, 2013, this exemption was repealed. If the transferor is a resident entity, capital gains deriving from the disposal of securities will be treated as any other taxable income subject to the 30% corporate Income Tax rate.

Furthermore, before December 31, 2012, if the transferor was a resident individual, the first five tax units (approximately US$6,800) of capital gains deriving from the transfer of securities were exempted from the Income Tax. Effective January 1, 2013, such exemption was repealed. Any capital gain earned by a resident individual is subject to the 5% annual Income Tax rate regardless of whether or not the transaction is carried out on the Lima Stock Exchange and regardless of how many transactions are carried out by such individual. In this case, the 5% Income Tax rate will be applicable over the annual net capital gain, which is calculated by deducting from the annual gross capital gain of the annual losses resulting from the disposal of shares during the same fiscal year.

Moreover, if the transferor, either a resident or nonresident individual or entity, acquired the ADSs or Common Shares that were exempt from the Income Tax before January 1, 2010, pursuant to a special provision of the ITL, the tax basis is the higher of: (i) the acquisition cost; (ii) the face or nominal value of the shares; or (iii) the stock market value at closing on December 31, 2009.

If the transferor, whether resident or nonresident in Peru, acquires the ADSs or Common Shares on or after January 1, 2010, the tax basis is: (i) for shares purchased by the transferor, the acquisition price paid for the shares; (ii) for shares received by the transferor as a result of a capital stock increase because of a capitalization of net profits, the face or nominal value of such shares; (iii) for other shares received free of any payment, the stock market value of such shares if listed on the Lima Stock Exchange or, if not, the face or nominal value of such shares; and (iv) for shares of the same type acquired at different opportunities and at different values, the tax basis will be the weighted average cost.

The aforementioned rules are also applicable to ADSs or Common Shares acquired before January 1, 2010 that were not exempt from the Income Tax as of December 31, 2009.

162

On December 31, 2010, Law No. 29645 was promulgated and took effect from January 1, 2011. This law states that in any transaction of Peruvian securities through the Lima Stock Exchange, CAVALI ICLV S.A. (the Peruvian clearing house) will act as withholding agent. As a result of this amendment, the nonresident will no longer have to self-assess and pay its Income Tax liability directly to the Peruvian Tax Administration.

Law No. 29645 has technically been in force since January 1, 2011. Implementing regulations were enacted in July 2011, and CAVALI ICLV S.A. began acting as a withholding agent on November 1, 2011. As a result, with regard to securities transferred through the Lima Stock Exchange by a nonresident transferor after November 1, 2011, such nonresident transferor is no longer obliged to self-assess and pay its Income Tax liability directly to Peruvian tax authorities within the first 12 working days following the month in which Peruvian source income was earned.

If the purchaser is a resident in Peru and the sale is not performed through the Lima Stock Exchange, the purchaser will act as withholding agent, except in cases in which the transferor is a resident individual.

However, if the transferor is a resident entity, such transferor is solely responsible for its Peruvian Income Tax on capital gains resulting from the disposal of ADSs or Common Shares, regardless of whether such securities are listed on the Lima Stock Exchange or elsewhere.

On September 12, 2015 Law No. 30341 was published. This law entered into effect on January 1, 2016 and states that capital gains from the disposal of ADSs or Common Shares through December 31, 2018 issued by legal entities incorporated in Peru, executed through the Lima Stock Exchange, are exempt from Peruvian Income Tax if: (i) within a period of twelve (12) months the holder and its related parties do not transfer 10% or more of the issued shares of the legal entity in one or more transactions; and (ii) the Common Shares issued by such legal entity shall have been continuously traded in the stock market (the rules to determine if such shares are continuously traded are set forth in Law No. 30341, as amended). Law No. 30341 was amended by Legislative Decree No. 1262, published on December 10, 2016 and effective since January 1, 2017, which introduced minor amendments related to capital gains deriving from the disposal of ADSs and Common Shares and extended this income tax exemption through December 31, 2019. Law No. 30341 was amended for a second time by Urgent Decree No. 005-2019, published on October 24, 2019 and effective on January 1, 2020, which introduced minor amendments regarding to the rules to determine when shares are continuously traded; and extended this income tax exemption through December 31, 2022.

Exchange Transactions

No Peruvian estate or gift taxes are imposed on the gratuitous transfer of ADSs or Common Shares. No stamp, transfer or similar tax applies to any transfer of Common Shares, except for commissions payable by seller and buyer to the Lima Stock Exchange (0.021% of value sold), fees payable to the SMV (0.0135% of value sold), brokers’ fees (about 0.05% to 1% of value sold) and VAT (at the rate of 18%) on commissions and fees. Any investor who sells its Common Shares on the Lima Stock Exchange will incur these fees and taxes upon purchase and sale of the Common Shares.

Other Considerations

As explained in Item 10. Memorandum and Articles of Association – Final Beneficial Owners, on August 2, 2018, Legislative Decree No. 1372 was published. This law entered into effect on August 3, 2018 and its regulations were enacted by Supreme Decree No. 003-2019-EF, published on January 8, 2019. According to this law and its regulations, legal entities domiciled or established in Peru must report the identity of their ultimate beneficial owners, as a tool for law enforcement agencies to confront tax evasion, money laundering and terrorist financing. For this reporting obligation, legal entities include any corporation, partnership or similar entity, trust, investment fund or joint venture. This obligation is also applicable to legal entities that are not domiciled in Peru but have a branch, subsidiary, joint venture or permanent establishment in Peru or, in the case of trusts, which have a grantor, settlor, beneficiaries or trustees domiciled in Peru. Ultimate beneficial owner is defined as the individual that effectively owns or controls a legal entity. For this purpose, ownership is when at least 10% of the capital of the legal entity is directly or indirectly under the ownership of an individual and its related parties. On September 25, 2019, the Tax Authority issued Superintendence Resolution No. 185-2019/SUNAT, establishing rules for this mandatory report and, for the legal entities that qualify as principal taxpayers as of November 30, 2019, the first deadline for filing this mandatory report was established within the first half of December 2019. The first deadline to present the affidavit with information regarding the final beneficiaries as of November 30, 2019 was set in the first half of December 2019.

163

Peruvian law was amended with the objective to grant greater guarantees to the taxpayers through application of the general anti-evasive rule (Rule XVI of the Preliminary Title in the Tax Code) and with the objective of providing more tools to the Tax Administration for effective implementation of the rule.

U.S. Federal Income Tax Considerations

Assuming the obligations contemplated by the Amended and Restated Deposit Agreement are being performed in accordance with its terms, holders of ADSs (or ADRs evidencing ADSs) generally will be treated for U.S. federal income tax purposes as the beneficial owners of the Common Shares represented by those ADSs. U.S. Holders should be aware that the U.S. Internal Revenue Service (the “IRS”) has expressed concerns that parties to whom ADSs are pre-released before common shares are delivered to the depositary, or intermediaries in the chain of ownership between holders of ADSs and the issuer of the security underlying the ADSs, may be taking actions that are inconsistent with the claiming of foreign tax credits by holders of ADSs. Accordingly, the creditability of any Peruvian taxes could be affected by actions taken by such parties or intermediaries.

Cash Dividends and Other Distributions

In general, distributions with respect to the ADSs or Common Shares will, to the extent made from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles, constitute dividends for U.S. federal income tax purposes. If a distribution exceeds the amount of our current and accumulated earnings and profits, as so determined under U.S. federal income tax principles, the excess will be treated first as a non-taxable return of capital to the extent of the U.S. Holder’s tax basis in the ADSs or Common Shares, and thereafter as capital gain. We do not intend to maintain calculations of our earnings and profits under U.S. federal income tax principles and, unless and until such calculations are made, U.S. Holders should assume all distributions are made out of earnings and profits and constitute dividend income. As used below, the term “dividend” means a distribution that constitutes a dividend for U.S. federal income tax purposes.

Cash dividends paid with respect to Common Shares or Common Shares represented by ADSs can generally be included in the gross income of a U.S. Holder as ordinary income. Dividends generally are treated as foreign source income. Dividends paid to a U.S. Holder that is a domestic corporation are not eligible for the dividends received deduction available to such corporations. Under current law, a reduced U.S. tax rate is imposed on the dividend income of an individual U.S. Holder with respect to dividends paid by a domestic corporation or “qualified foreign corporation” if certain holding period requirements are met. A qualified foreign corporation generally includes a foreign corporation that is not a passive foreign investment company (“PFIC”) in the year in which the dividend is pair or in the preceding taxable year and either (i) its shares are readily tradable on an established securities market in the United States or (ii) it is eligible for benefits under a comprehensive U.S. income tax treaty. Clause (i) should apply with respect to the ADSs as long as the ADSs are traded on the New York Stock Exchange. As a result,  provided that we are not a PFIC in the year in which the dividend is paid or in the preceding taxable year, we should be treated as a qualified foreign corporation and, therefore, dividends paid to an individual U.S. Holder with respect to ADSs for which the minimum holding period requirement is met should be taxed at a reduced rate. In the case of our Common Shares held directly by U.S. Holders and not underlying ADSs, it is not clear whether dividends paid with respect to such shares will represent “qualified dividend income.” U.S. Holders holding our Common Shares directly and not through an ADS are urged to consult their own independent tax advisors.

Dividends paid in Soles are includible in a U.S. dollar amount based on the exchange rate in effect on the date of receipt (which, in the case of ADSs, will be the date of receipt by the Depositary) whether or not the payment is converted into U.S. dollars at that time. Any gain or loss recognized upon a subsequent sale or conversion or other taxable disposition of the Soles for a different amount of U.S. dollars will be U.S. source ordinary income or loss for U.S. federal income tax purposes. Distributions to U.S. Holders of additional Common Shares or preemptive rights with respect to Common Shares that are made as part of a pro rata distribution to all of our shareholders generally will not be subject to U.S. federal income tax but in other circumstances may constitute a taxable dividend.

164

A U.S. Holder will generally be entitled to claim a U.S. foreign tax credit in respect of any Peruvian taxes imposed on dividends received on our Common Shares or Common Shares represented by ADSs, subject to generally applicable limitations and restrictions and provided that the withholding tax constitutes a “covered withholding tax” under recent U.S. regulations.In the case of U.S. individuals for whom the reduced rate of tax on dividends applies, such limitations and restrictions will appropriately take into account the rate differential under rules similar to section 904(b)(2)(B) of the Code. U.S. Holders who do not elect to claim a credit for foreign taxes may instead claim a deduction in respect of such Peruvian taxes. Dividends received with respect to our Common Shares or Common Shares represented by ADSs may be treated as foreign source income for U.S. federal income tax purposes, and will be “passive category income” for purposes of calculating foreign tax credits in most cases, subject to various limitations. The rules governing foreign tax credits are complex, recent U.S. regulations have imposed additional requirements that must be met for a foreign tax to be creditable (including requirements that a “covered withholding tax” be imposed on nonresidents in lieu of a generally applicable tax that satisfies the regulatory definition of an “income tax,” which may be unclear or difficult to determine), and U.S. Holders should consult their tax advisors regarding their application to the particular circumstances of such holder.

A non-U.S. Holder generally is not subject to U.S. federal income or withholding tax on dividends paid with respect to Common Shares or Common Shares represented by ADSs, unless such income is effectively connected with the conduct by the non-U.S. Holder of a trade or business within the United States.

Capital Gains

U.S. Holders will recognize taxable gain or loss on the sale or other taxable disposition of ADSs or Common Shares (or preemptive rights with respect to such shares) held by the U.S. Holder or by the Depositary in an amount equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holder’s adjusted tax basis in the ADSs or Common Shares. Generally, such gain or loss will be a long-term capital gain or loss if the U.S. Holder’s holding period for such Common Shares or ADSs exceeds one year. Long-term capital gain for an individual U.S. Holder is generally subject to a reduced rate of U.S. federal income tax. The deductibility of capital losses is subject to limitations under the Code. Under recent U.S. regulations mentioned above, Peruvian withholding tax imposed on such U.S. source gain may not constitute a creditable tax. Moreover, in the case of a sale or other taxable disposition of Common Shares or ADSs in a transaction subject to Peruvian tax, even if the tax is a creditable tax, the U.S. Holder may not be able to claim a U.S. foreign tax credit for any Peruvian tax imposed on the gain unless it has sufficient foreign source income from other sources against which it can apply the credit.

For U.S. federal income tax purposes, U.S. Holders will not recognize gain or loss on deposits or withdrawals of Common Shares in exchange for ADSs or on the exercise of preemptive rights.

A non-U.S. Holder of ADSs or Common Shares will not be subject to U.S. federal income or withholding tax on gain from the sale or other disposition of ADSs or Common Shares unless (i) such gain is effectively connected with the conduct of a trade or business within the United States or (ii) the non-U.S. Holder is an individual who is present in the United States for at least 183 days during the taxable year of the disposition and (iii) certain other conditions are met.

Passive Foreign Investment Company

Based on our audited financial statements as well as relevant market and shareholder data, we believe that we were not a PFIC for U.S. federal income tax purposes with respect to our 2020 taxable year. However, although unclear, we can provide no assurance that we did not become a PFIC in our 2021 taxable year, as a result, in part of, changes in our income and the value of our assets and uncertainty as to the chacterization of certain assets. In particular, the conclusion could be affected by a pending tax refund claim the characterization of which for PFIC purposes is unclear and the value of which is highly speculative. For the same reason and also taking into account the effect of the Company’s sale of its stake in Yanacocha on February 7, 2022, even if we were not a PFIC for our 2021 taxable year, we cannot assure you that we will not become a PFIC with respect to our current taxable year. Furthermore, because a determination of our PFIC status is based on our income, assets and the nature of our business, as well as the income, assets and business of entities in which we hold at least a 25% interest, from time to time, involves the application of complex tax rules, including the application of proposed United States Treasury Regulations, on which we are entitled to rely until they are finalized, and since our view is not binding on the courts or the IRS, no assurances can be provided that we will not be considered a PFIC for the current, or any past or future tax year. The potential application of the PFIC rules is further discussed below.

165

A foreign corporation is a PFIC in any taxable year in which, after taking into account the income and assets of certain subsidiaries pursuant to the applicable look-through rules, either (i) at least 75% of its gross income is passive income or (ii) at least 50% of the average value of its assets is attributable to assets that produce passive income or are held for the production of passive income. Passive income generally includes interest, dividends, rents, royalties and certain gains (including certain commodity related gains), but active business gains from the sale of commodities is not considered “passive income” for purposes of determining whether a company is a PFIC. Our PFIC status for any taxable year is likely to depend upon the extent to which our gross profit from our mining activities is considered active business gains.

A U.S. Holder would also be subject to additional taxes on any excess distributions received from us and any gain realized from the sale or other disposition of ADSs or Common Shares (regardless of whether we continued to be a PFIC) unless such U.S. Holder makes an election to be taxed currently on its pro rata portion of our income, whether or not such income is distributed in the form of dividends, or otherwise makes a “mark-to-market” election with respect to the ADSs or Common Shares as permitted by the Code. A U.S. Holder has an excess distribution to the extent that distributions on ADSs or Common Shares during a taxable year exceed 125% of the average amount received during the three preceding taxable years (or, if shorter, the U.S. Holder’s holding period for the ADSs or Common Shares). To compute the tax on an excess distribution or any gain, (i) the excess distribution or the gain is allocated ratably over the U.S. Holder’s holding period for the ADSs or Common Shares, (ii) the amount allocated to the current taxable year is taxed as ordinary income and (iii) the amount allocated to other taxable years is taxed at the highest applicable marginal rate in effect for each year and an interest charge is imposed to recover the deemed benefit from the deferred payment of the tax attributable to each year.

If we were a PFIC, U.S. Holders of interests in a holder of ADSs or Common Shares may be treated as indirect holders of their proportionate share of the ADSs or Common Shares and may be taxed on their proportionate share of any excess distribution or gain attributable to the ADSs or Common Shares. An indirect holder also must treat an appropriate portion of its gain on the sale or taxable disposition of its interest in the actual holder as gain on the sale or taxable disposition of the ADSs or Common Shares.

U.S. Holders are urged to consult their own independent tax advisors regarding the potential application of the PFIC rules and related reporting requirements to the Common Shares or ADSs and the availability and advisability of making an election to avoid the adverse tax consequences of the PFIC rules should we be considered a PFIC for any taxable year.

Information Reporting and Backup Withholding

Dividends in respect of the ADSs or Common Shares and the proceeds from the sale, exchange, redemption or other disposition of the ADSs or Common Shares may be reported to the IRS and a backup withholding tax may apply to such amounts unless the holder (i) is a corporation (which may be required to establish its exemption by certifying its status on IRS Form W-9), (ii) in the case of a U.S. Holder other than a corporation, provides an accurate taxpayer identification number in the manner required by applicable law, (iii) in the case of a non-U.S. Holder, provides a properly executed IRS Form W-8BEN or W-8BEN-E or other applicable Form W-8, or (iv) otherwise establishes a basis for exemption. The amount of any backup withholding from a payment to a U.S. Holder generally may be allowed as a credit against the U.S. Holder’s U.S. federal income tax liability.

“Specified Foreign Financial Asset” Reporting

U.S. Holders of “specified foreign financial assets” with an aggregate value in excess of US$50,000 (and in some circumstances, a higher threshold), may be required to file an information report with respect to such assets with their U.S. federal income tax returns. “Specified foreign financial assets” generally include any financial accounts maintained by foreign financial institutions as well as any of the following, but only if they are not held in accounts maintained by financial institutions: (i) stocks and securities issued by non-U.S. persons, (ii) financial instruments and contracts held for investment that have non-U.S. issuers or counterparties and (iii) interests in foreign entities.

We are subject to the informational requirements of the Exchange Act. Accordingly, we are required to file reports and other information with the SEC, including annual reports on Form 20-F and reports on Form 6-K. The SEC maintains an Internet website that contains reports and other information about issuers, like us, that file electronically with the SEC. The address of that website is www.sec.gov.

See “Item 4. Information of the Company Buenaventura—C. Organizational Structure”

ITEM 11.Quantitative and Qualitative Disclosures About Market Risk

The following discussion contains forward-looking statements that are subject to risks and uncertainties, many of which are outside of our control. Our primary market risks are related to fluctuations in the prices of gold, silver, zinc and lead. To a lesser extent, we are subject to market risk related to fluctuations in US$/ Sol exchange rates and to market risk related to interest rate fluctuation on our cash balances.

Commodity Contracts

Gold, silver, lead and copper hedging and sensitivity to market price

Our revenues and earnings are to a great extent influenced by world market prices for gold, copper, silver, zinc and lead that fluctuate widely and over which we have no control. We and our wholly owned subsidiaries are completely unhedged as to the price at which our gold and silver will be sold. See “Item 3. Key Information—D. Risk Factors—Factors Relating to the Company—Our financial performance is highly dependent on the prices of gold, silver, copper and other metals.”

As of March 31, 2022, we had no silver derivative contracts or gold convertible put option contracts in place.

From January to December 2022, El Brocal had outstanding hedging commitments amounting to 24,500 fines tons of copper at an average fixed price of US$9,476 per ton and 6,000 fines tons of zinc at an average fixed price of US$3,716 per ton.

Cerro Verde has informed us that they have generally not engaged in, and are currently not engaged in, gold or copper price hedging activities, such as forward sales or option contracts, to minimize their exposure to fluctuations in the prices of gold or copper.

Normal Sales

We had no normal sales contracts with fixed or capped prices outstanding as of March 31, 2022.

Foreign currency risk

We buy and sell our products and obtain capital facilities and investment in U.S. Dollars. The assets and liabilities in different currencies from the U.S. Dollar (Soles) are not significant. We estimate that the future exchange rate fluctuations of Peruvian currency versus the U.S. Dollar will not significantly affect the results of our future operations. See Note 35(a).1.

Interest Rate Sensitivity

We reduce our exposure to the risks due to variations in interest rates by engaging in financial obligations and capital leasing with fixed interest rates. See Note 35(a.3) to the Consolidated Financial Statements. Consequently, we do not use derivative instruments to manage this risk and we do not expect to incur significant losses based on interest risks.

The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for depositary services by making deductions from cash distributions,by directly billing investors or by charging the book-entry system accounts of participants acting for them. The Depositary may generally refuse to provide fee-attracting services until its fees for those services are paid. The following table summarizes the fees and expenses payable by holders of ADSs:

Persons depositing or withdrawing shares must pay:	Payable to:	For:
US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs)	Depositary	Issuance of ADSs, including issuances resulting from a distribution of shares or rights or other property
US$5.00 (or less) per 100 ADSs (or portion of 100 ADSs)	Depositary	Cancellation of ADSs for the purpose of withdrawal, including if the deposit agreement terminates

168

Fees Incurred in Past Annual Period

From January 1, 2021 to May 13, 2022, we received no fees from the Depositary related to our ADR facility, including continuing annual stock exchange listing fees, standard out-of-pocket maintenance costs for the ADRs (consisting of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend checks, electronic filing of U.S. federal tax information, mailing required tax forms, stationery, postage, facsimile, and telephone calls), any applicable performance indicators relating to the ADR facility, underwriting fees and legal fees.

169

Fees to be Paid in the Future

The Depositary has agreed to reimburse us for expenses we incur that are related to establishment and maintenance expenses of the ADS program. The Depositary has agreed to reimburse us for our continuing annual stock exchange listing fees. The Depositary has also agreed to pay the standard out-of-pocket maintenance costs for the ADRs, which consist of the expenses of postage and envelopes for mailing annual and interim financial reports, printing and distributing dividend checks, electronic filing of U.S. federal tax information, mailing required tax forms, stationery, postage, facsimile and telephone calls. It has also agreed to reimburse us annually for certain investor relationship programs or special investor relations promotional activities. In certain instances, the Depositary has agreed to provide additional payments to us based on any applicable performance indicators relating to the ADR facility. There are limits on the amount of expenses for which the Depositary will reimburse us, but the amount of reimbursement available to us is not necessarily tied to the amount of fees the Depositary collects from investors.

The Depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The Depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The Depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them. The Depositary may generally refuse to provide fee-attracting services until its fees for those services are paid.

ITEM 15.Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of December 31, 2021, we carried out an evaluation under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon and as of the date of our evaluation, our Chief Executive Officer and Chief Financial Officer concluded that the disclosure controls and procedures are effective at providing reasonable assurance that information required to be disclosed in the reports we file and submit under the Exchange Act is recorded, processed, summarized and reported as and when required.

Management’s Annual Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external reporting purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2021. In making its assessment, management has utilized the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Our management concluded that based on its assessment, our internal control over financial reporting was effective as of December 31, 2021.

Our independent registered public accounting firm Tanaka, Valdivia & Asociados S. Civil de R.L., has issued an attestation report on our internal control over financial reporting, which is included below.

Report of Independent Registered Public Accounting Firm

We have audited Compañia de Minas Buenaventura S.A.A. and subsidiaries internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), (the COSO criteria). In our opinion, Compañia de Minas Buenaventura S.A.A. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of financial position of the Company as of December 31, 2021 and 2020, the related consolidated statements of profit or loss, other comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes and our report dated May 13, 2022, expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance International Financial Reporting Standards as issued by the International Accounting Standard Board. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance International Financial Reporting Standards as issued by the International Accounting Standard Board, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

173

ITEM 16G.Corporate Governance

There are significant differences in the corporate governance practices followed by us as compared to those followed by U.S. domestic companies under the NYSE, listing standards. The NYSE listing standards provide that the board of directors of a U.S. domestic listed company must consist of a majority of independent directors and that certain committees must consist solely of independent directors. Under Peruvian corporate governance practices, a Peruvian company is not required to have a majority of the members of the board of directors be independent.

The listing standards for the NYSE also require that U.S. domestic companies have an audit committee, a nominating/corporate governance committee and a compensation committee. Each of these committees must consist solely of independent directors and must have a written charter that addresses certain matters specified in the listing standards. Peruvian corporate governance practices permit the board of directors of a Peruvian company to form special governance bodies in accordance with the needs of such company and do not require that these special governance bodies be composed partially or entirely of independent directors. We maintain four committees, which include the Audit Committee, the Compensation and Nominating Committee, the Corporate Governance Committee and the Innovation and Sustainability Committee. Our Board has determined that our Audit Committee is composed entirely of independent directors, as defined in the NYSE’s Listed Company Manual.

The NYSE’s listing standards also require U.S. domestic companies to adopt and disclose corporate governance guidelines. In July 2002, the SMV and a committee composed of regulatory agencies and associations prepared and published a list of suggested corporate governance guidelines called “Principles of Good Governance for Peruvian Companies.” These principles are disclosed on the SMV’s website at http://www.smv.gob.pe.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders of Compañía de Minas Buenaventura S.A.A.

Opinion on the Financial Statements

We have audited the accompanying consolidated statements of financial position of Compañía de Minas Buenaventura S.A.A., and Subsidiaries (together the Group) as of December 31, 2021 and 2020, the related consolidated statements of profit or loss, other comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Group at December 31, 2021 and 2020, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) the Group´s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated May 13, 2022 expressed an unqualified opinion thereon.

Basis for Opinion

These consolidated financial statements are the responsibility of the Group ‘s management. Our responsibility is to express an opinion on the Group ‘s consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Impairment of mining concessions, development costs, right-of-use asset, property, plant and equipment

Description of the Matter

At December 31, 2021, the net carrying value of the Group’s mining concessions, development costs, right-of-use asset, and property, plant and equipment was US$1,538 million. Related disclosures are included in Note 2.4(n) and Note 11(b) to the consolidated financial statements. The Group reviews and evaluates its mining concessions, development costs, right-of-use asset, and property, plant and equipment for impairment at least annually, or when events or changes in circumstances indicate that the related carrying amounts may not be recoverable at the Cash Generating Unit level (CGUs). When the Group determines the existence of significant impairment indicators, management performs an assessment to determine whether an impairment has occurred. An impairment exists when the carrying value of an asset or CGU exceeds its recoverable amount, which is the higher of its fair value less costs to sell and its value in use. On the other hand, a previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset or CGU’s recoverable amount since the last impairment loss was recognized. The Company has estimated the value in use (VIU) at the CGU level to test for impairment. During 2021, the Group recognized an impairment in long lived assets of the Group’s Rio Seco CGU of US$19.9 million and a reversal of impairment in the La Zanja CGU of US$5.0 million. Auditing the Group´s long-lived assets impairment tests was complex and highly judgmental due to the significant estimation required to determine the VIU of each CGU. In particular the VIU estimates were sensitive to significant assumptions, among others, the production volumes, current life of mine plans, market-based commodity price assumptions, discount rates that reflect the current market assessments of the time value of money and the risks specific to the CGU, including estimated quantities of recoverable minerals and residual value.

F-4

Report of Independent Registered Public Accounting Firm (continued)

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design, and tested the operating effectiveness of controls over the Group´s impairment review process, including controls over the Group’s process for identifying and evaluating potential impairment and reversal indicators, management´s review of the significant assumptions described above, projected financial information and the methodology used to develop such estimates. To test the estimated VIU of the Group´s CGUs, we performed audit procedures that included, among others, assessing methodologies and testing the significant assumptions discussed above and the underlying data used by the Company in its analysis. We assessed the projected financial information by comparing forecasted commodity prices to available market information and internal business plans. We also assessed the future production levels used in the impairment analyses, which are based on the life of mine plans by comparing them to historical estimates, actual results and inspected supporting analyses. We involved our valuation specialists to assist in comparing market-based commodity price assumptions used against market data including a range of analysts’ forecasts. Additionally, our valuation specialists evaluated the discount rates used against current industry and economic trends as well as the Group-specific risk premiums applied. We also performed sensitivity analyses over changes in the discount rates and commodity price assumptions to evaluate the change in the recoverable amount of the CGU that would result from changes in the assumptions. The Group engages independent consultants to validate the estimated quantity of recoverable minerals reserves performed by management’s qualified persons, which were used in the impairment analyses. We inspected the independent consultants’ reports and evaluated their competence and objectivity as well as the competence of management’s qualified persons. Furthermore, we evaluated the Group´s estimated quantities of recoverable minerals by comparing them with the historical operating performance of the CGUs. Furthermore, we evaluated the disclosure of this matter in Note 2.4(n) and Note 11(b) to the consolidated financial statements. ​

Report of Independent Registered Public Accounting Firm (continued)

Uncertain tax positions

Description of the Matter

As disclosed in Note 31(d) to the consolidated financial statements, the Group has identified certain income tax-related contingencies associated to the tax years of 2007 through 2010, 2013 and 2014. In these years, relevant taxation authorities have challenged the tax treatment applied by the Group under the income tax law in Peru. As of December 31, 2021 the Group has recognized an income tax receivable for an amount of $591.8 million, resulting from payments made to the taxation authorities as part of the tax claim process in Peru but for which the Group is disputing the validity of the taxation authorities’ assessment. The Group has disclosed, but has not recorded a provision related to these matters, as management has concluded that the criteria for recognition of an income tax liability under IFRS has not been met and that the amounts paid to date are recoverable based upon the technical merits of the income tax positions taken by the Group. Uncertainty in a tax position may arise where there is an uncertainty as to the meaning of the tax law, or the applicability of the tax law to a particular transaction or both. The Group uses significant judgment to determine whether, based on the technical merits, a tax position is more likely than not to be sustained and in the determination of the recoverable amount of the income tax receivable that qualifies for recognition. Auditing the estimation of the outcome and measurement of the uncertain tax positions and the related recoverability of income tax receivables, before the uncertain tax treatment is resolved, requires a high degree of auditor judgment and significant audit effort due to the complexity and judgement used by the Group in the assessment based on interpretations of the income tax legislation and legal rulings in Peru.

F-6

Report of Independent Registered Public Accounting Firm (continued)

How We Addressed the Matter in Our Audit We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Group’s accounting process for income taxes, including uncertain tax positions and tax contingencies, for example, we tested the controls over management’s review of the technical merits of tax positions, disputed tax assessments and the determination and approval of the recoverable amount of the income tax receivable. ​ Our audit procedures included, among others, evaluating the assumptions used by the Group to develop its uncertain tax positions based on relevant Peruvian income tax laws, including the inspection of the Group´s internal and external counsel analysis of these matters. ​ In addition, we involved our tax subject matter professionals to assess the technical merits of the Group’s tax position and to evaluate the application of relevant tax law and accounting guidance in assessing the recognition and recoverability of the related income tax receivables. ​ Furthermore, we evaluated the disclosure of this matter in Note 31(d) to the consolidated financial statements. ​

Compañía de Minas Buenaventura S.A.A. and Subsidiaries

Notes to the consolidated financial statements

For the years 2021, 2020 and 2019

1.     Identification and business activity

(a)          Identification -

Compañía de Minas Buenaventura S.A.A. (hereafter “the Company” or “Buenaventura”) is a publicly traded corporation incorporated in Peru in 1953. The Company stock is traded on the Lima and New York Stock Exchanges through American Depositary Receipts (ADRs), which represent the Company’s shares deposited in the Bank of New York. The Company’s legal domicile is at Las Begonias Street N°415, San Isidro, Lima, Peru. The Company is the ultimate controlling party.

(b)          Business activity -

The Company and its subsidiaries (hereinafter “the Group") are principally engaged in the exploration, mining, concentration, smelting and marketing of polymetallic ores and metals.

The Company operates directly four operating mining units in Peru (Uchucchacua, Orcopampa, Julcani and Tambomayo), two discontinued mining units (Poracota and Shila-Paula), and one mining unit under development stage (San Gabriel). In addition, the Company has a controlling interest in (i) Sociedad Minera El Brocal S.A.A. (hereinafter “El Brocal”), which operates the Colquijirca mining unit; (ii) Minera La Zanja S.R.L. (hereinafter “La Zanja”), which operates La Zanja mining unit; (iii) El Molle Verde S.A.C. (hereinafter “Molle Verde”) which operates Trapiche, a mining unit at the development stage; and (iv) other entities dedicated to energy generation and transmission services, and other activities. All these activities are carried out in Peru. In addition, the Group has a non-significant subsidiary in Mexico related to exploration activities.

Temporary suspension of production at the Uchucchacua mining unit -The Uchucchacua mining unit has presented operational problems that were aggravated by the COVID-19 pandemic (delays in the preparation and exploration of the mine), which forced the Company to reduce the production estimates announced for the years 2020 and 2021. For this reason, on October 15, 2021 Buenaventura requested that the Ministry of Energy and Mines, approve the temporary suspension of activities at its Uchucchacua mine, specifically those related to mining exploitation activities.

The Company's management has estimated that the temporary suspension at the Uchucchacua mining unit will not significantly affect the cash flows originally estimated for the years 2021 and 2022 and, on the contrary, it will allow all the efforts of the operations team to be focused on implementing measures aimed at achieving efficiencies and reducing the cost of operations by the time it is decided to restart. The Company's management evaluated and concluded that there is no impairment of the assets of the Uchucchacua mining unit as a result of the analysis of the recoverable amount based on its value in use, as the temporary stoppage has not significantly affected the value in use.

During the temporary suspension of production, measures will be implemented that will aim to achieve greater operational efficiency, focused on the new strategy for the period 2021 - 2023 focused on exploration activities, re-engineering or redesign of the mine, and on the development of the Yumpag project. Additionally, during the period of temporary suspension of production, the Company will focus on improving the relationship with local communities and will continue with the work related to environmental commitments, such as monitoring, water treatment, waste collection, progressive mine closure, among others.

As a result, the industrial activities in the subsidiary Procesadora Industrial Río Seco S.A. (which receives raw materials from the Uchucchacua mining unit) are suspended until the restart of Uchucchacua’s operations. As of December 31, 2021, the Group had recognized an impairment in this subsidiary; see detail in note 11(b).

(f)          COVID-19 (Corona Virus Disease 2019) in Peru

The Group’s operations are subject to risks related to outbreaks of infectious diseases. For example, the recent outbreak of coronavirus COVID-19. Since March 15, 2020, and by means of Supreme Decree No. 044-2020, the Peruvian State declared a State of National Emergency and mandatory social isolation for an initial period of fifteen calendar days, with subsequent extensions. During the initial phase, constitutional rights related to personal freedom and security, inviolability of the home and freedom of assembly were restricted, except for the provision and access to certain services

F-16

Notes to the consolidated financial statements (continued)

and essential goods, such as those related to financial institutions, insurance and pensions, as well as complementary and related services. Operations at a national level have now resumed according to a phase plan issued by the Peruvian State.

In March, April, May and June 2020, direct operations of the Group were limited to those that are critical to ensuring the functionality of the mine pumping systems, water treatment plants, energy supply, hydroelectric substations, health services and overall minimum safety conditions, administrative supervision, security conditions, including filling and general support, among others. The production stoppage dates were as follows:

Phase 1 (initiated on May 16, 2020)

● Tambomayo

● Uchucchacua

● El Brocal (Tajo Norte and Marcapunta)

Phase 2 (initiated on June 16, 2020)

● Orcopampa

● Julcani

● La Zanja

Considering that the start of the quarantine began in the second half of March, the Group's mining units have operated below the planned volume for 2020, which is reflected in the variation in sales. In 2020, the Group's unabsorbed cost due to production stoppage amounted to a total amount of US$27.8 million (net of intercompany eliminations), see note 22.

Depreciation and amortization incurred during the production stoppage amounts to US$10.8 million for the year 2020, which is included in “Depreciation and amortization” caption in the consolidated statements of profit or loss.

In January 2021, in response to the significant increase in the number of infections, the number of deaths and the saturation of the health system, the Peruvian Government decreed compulsory social immobilization in ten regions of the country, with the exception of some sectors such as agriculture, energy, hydrocarbons, mining, construction, etc., thus it did not affect the Company's operations. This second confinement phase, had an initial period of fifteen days from January 31, being extended by 14 days until February 28, 2021. As of March 1, 2021 and for an initial period of 14 days (which continued to be renewed throughout 2021 and into 2022), new measures have been applied to mitigate the COVID-19 pandemic in the country.

The ultimate severity of the Coronavirus outbreak is uncertain at this time and therefore the Group cannot predict the possible impact on the world, the Peruvian economy, the international financial markets, or ultimately on the Group’s financial condition. However, as part of the business continuity and progress of operations, the Group has been executing its business plan, which expects that sales levels will continue to increase in the short and medium term, considering normal regularization of operations, the current commercial landscape and increase in metal prices.

2.     Basis for preparation, consolidation and accounting policies

2.1.     Basis of preparation -

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB).

F-17

Notes to the consolidated financial statements (continued)

The consolidated financial statements have been prepared on a historical cost basis, based on the records of the Company, except for the derivative financial instruments and financial assets and liabilities that have been measured at fair value and discontinued operations that have been valued at the lower of (i) their carrying amount and (ii) its fair value less cost to sell.

The consolidated financial statements are presented in U.S. dollars and all values are rounded to the nearest thousands, except when otherwise indicated.

The preparation of consolidated financial statements requires that management use judgments, estimates and assumptions, as detailed on the following note 3.

These consolidated financial statements provide comparative information in respect of prior periods.

Reclassifications of comparative information –

The Group reclassified current and non-current liabilities for US$16,184,000 and US$2,742,000, respectively, in the balances as of December 31, 2020 in accordance with IAS 1 - Presentation of Financial Statements. These concepts were presented together with the “Provisions and contingent liabilities” and are now presented as part of the “Trade and other payables” caption of the consolidated financial statement as of December 31, 2020.

F-18

Notes to the consolidated financial statements (continued)

2.2.     Basis of consolidation -

The consolidated financial statements comprise the financial statements of the Company and its subsidiaries to the date of the consolidated statements of financial position.

Control is achieved when the Group is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Group controls an investee if, and only if, the Group has:

- Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee).

- Exposure, or rights, to variable returns from its involvement with the investee.

- The ability to use its power over the investee to affect its returns.

Generally, there is a presumption that a majority of voting rights result in control. To support this presumption and when the Group has less than a majority of the voting or similar rights of an investee, the Group considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

- The contractual arrangement with the other vote holders of the investee.

- Rights arising from other contractual arrangements.

- The Group’s voting rights and potential voting rights or a combination of rights.

The Group re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Group obtains control over the subsidiary and ceases when the Group loses control of the subsidiary. Assets, liabilities, revenue and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Group gains control until the date the Group ceases to control the subsidiary.

Profit or loss and each component of other comprehensive income are attributed to the equity holders of the parent of the Group and to the non-controlling interests, even if this results in the non-controlling interests having a deficit balance. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with the Group’s accounting policies.

All intra-group assets and liabilities, equity, revenue, expenses and cash flows relating to transactions between members of the Group are eliminated in full on consolidation. A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction.

If the Group loses control over a subsidiary, it derecognizes the related assets (including goodwill), liabilities, non-controlling interest and other components of equity, while any resultant gain or loss is recognized in profit or loss. Any investment retained is recognized at fair value.

2.3.      Changes in accounting policies and disclosures -

Certain standards and amendments became effective in 2021; however, they did not have a material impact on the consolidated financial statements of the Group and therefore, have not been disclosed. The Group has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

Interest Rate Benchmark Reform – Phase 2 Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 -

The amendments provide temporary reliefs which address the financial reporting effects when an interbank offered rate (IBOR) is replaced with an alternative nearly risk-free interest rate (RFR). The amendments include the following practical expedients:

F-19

Notes to the consolidated financial statements (continued)

-A practical expedient to require contractual changes, or changes to cash flows that are directly required by the reform, to be treated as changes to a floating interest rate, equivalent to a movement in a market rate of interest.

-Permit changes required by IBOR reform to be made to hedge designations and hedge documentation without the hedging relationship being discontinued.

-Temporary relief provided to entities from having to meet the separately identifiable requirement when an RFR instrument is designated as a hedge of a risk component.

On March 5, 2021, the UK authorities confirmed that London IBOR rates would cease to be published with effect as of December 31, 2021 at all terms and in all currencies except for U.S. dollars, publication of which would continue until June 30, 2023 to facilitate the transition of current contracts. Due to this reform, which will apply to the Group through June 30, 2023, at the reporting date the amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 had no impact on the consolidated financial statements.

Covid-19-Related Rent Concessions beyond 30 June 2021 Amendments to IFRS 16 -

On May 28, 2020, the IASB issued Covid-19-Related Rent Concessions - amendment to IFRS 16 Leases. The amendments provide relief to lessees from applying IFRS 16 guidance on lease modification accounting for rent concessions arising as a direct consequence of the Covid-19 pandemic. As a practical expedient, a lessee may elect not to assess whether a Covid-19 related rent concession from a lessor is a lease modification. A lessee that makes this election accounts for any change in lease payments resulting from the Covid-19 related rent concession in the same way it would account for the change under IFRS 16 if the change were not a lease modification. The amendment was intended to apply until June 30, 2021, but as the impact of the pandemic is continuing, on March 31, 2021, the IASB extended the period of application of the practical expedient to June 30, 2022. The amendment applies to annual reporting periods beginning on or after April 1, 2021. However, the Group has not received Covid-19-related rent concessions but plans to apply the practical expedient if it becomes applicable to it in subsequent periods.

2.4.      Summary of significant accounting policies –

(a) Foreign currencies -

The Group´s consolidated financial statements are presented in U.S. dollars, which is also the parent company’s functional currency. For each entity, the Group determines the functional currency and the items included in the financial statements of each entity are measured using that functional currency. For consolidation purposes, each entity presents its financial statements in U.S. dollars.

Transactions and balances

Transactions in foreign currency are initially recorded by the Group at the exchange rates prevailing at the dates of the transactions, published by the Superintendence of Banking and Insurance and Pension Fund Administrators (AFP for its acronym in Spanish).

Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rates of exchange at the reporting date.

Differences arising from the settlement or translation of monetary items are recognized in profit or loss with the exception of monetary items that are designated as part of a hedge. These are recognized in other comprehensive income (OCI) until the hedged items are disposed of, at which time, the cumulative amount is reclassified to profit or loss. Tax charges and credits attributable to exchange differences on those monetary items are also recognized in OCI.

Non-monetary assets and liabilities recognized in terms of historical cost are translated using the exchange rates prevailing at the dates of the initial transactions.

F-20

Notes to the consolidated financial statements (continued)

(b) Financial instruments - Initial recognition and subsequent measurement -

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

(i) Financial assets -

Initial recognition and measurement -

Financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through OCI, and fair value through profit or loss.

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Group’s business model for managing them. Except for trade receivables that do not contain a significant financing component, the Group initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs.

For a financial asset to be classified and measured at amortized cost or fair value through OCI, it needs to give rise to cash flows that are “solely payments of principal and interest (SPPI)” on the principal amount outstanding. This assessment is performed at an instrument level.

The Group’s business model for managing financial assets refers to how it manages its financial assets in order to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both.

Purchases or sales of financial assets that require delivery of assets within a period established by regulation or convention in the marketplace (regular way trades) are recognized on the trade date.

Subsequent measurement -

For purposes of subsequent measurement, financial assets are classified in the following categories:

- Financial assets at amortized cost.

- Financial assets at fair value through OCI.

- Financial assets at fair value through profit or loss.

Financial assets at amortized cost -

The Group measures financial assets at amortized cost if both of the following conditions are met:

- The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows, and

- The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

Financial assets at amortized cost are subsequently measured using the effective interest (EIR) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired.

This category generally applies to other receivables included in the “Trade and other receivables, net” caption.

Financial assets at fair value through OCI -

Financial assets are classified and measured at fair value through OCI if they are held in a business model whose objective is achieved by both collecting contractual cash flows and selling financial assets.

This category generally applies to the “Hedge derivative financial instruments” caption.

F-21

Notes to the consolidated financial statements (continued)

Financial assets at fair value through profit or loss -

Financial assets at fair value through profit or loss include financial assets held for trading and financial assets designated upon initial recognition at fair value through profit or loss or financial assets mandatorily required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments. Financial assets with cash flows that are not solely payments of principal and interest are classified and measured at fair value through profit or loss, irrespective of the business model. Notwithstanding the criteria for debt instruments to be classified at amortized cost or at fair value through OCI, as described above, debt instruments may be designated at fair value through profit or loss on initial recognition if doing so eliminates, or significantly reduces, an accounting mismatch.

Financial assets at fair value through profit or loss are carried in the consolidated statements of financial position at fair value with net changes in fair value recognized in the consolidated statements of profit or loss.

This category generally applies to the trade receivables included in the “Trade and other receivables, net” caption.

Derecognition -

A financial asset (or, where applicable a part of a financial asset or part of a group of similar financial assets) is primarily derecognized when:

- The rights to receive cash flows from the asset have expired; or

- The Group has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a pass-through arrangement; and either (a) the Group has transferred substantially all the risks and rewards of the asset or, (b) the Group has neither transferred nor retained substantially all the risks and rewards of the asset but has transferred control of the asset.

When the Group has transferred its rights to receive cash flows from an asset or has entered a pass-through arrangement, it evaluates to what extent, it has retained the risk and rewards of ownership. When it has neither transferred nor retained substantially all the risks and rewards of the asset, nor transferred control of the asset, the Group continues to recognize the transferred asset to the extent of the Group´s continuing involvement. In that case, the Group also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Group has retained.

Impairment of financial assets -

The Group recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Group expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms.

ECLs are recognized in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL).

For trade receivables and contract assets, the Group applies a simplified approach in calculating ECLs. Therefore, the Group does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. The Group has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

F-22

Notes to the consolidated financial statements (continued)

The Group considers a financial asset in default when contractual payments are past due according to each contract. However, in certain cases, the Group may also consider a financial asset to be in default when internal or external information indicates that the Group is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Group. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.

(ii) Financial liabilities -

Initial recognition and measurement -

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans, borrowings and payables, net of directly attributable transaction costs.

The Group’s financial liabilities include trade and other payables, financial obligations, bank loans, financial liabilities for contingent consideration liability and Hedge derivative financial instruments.

Subsequent measurement -

The measurement of financial liabilities depends on their classification, as described below:

Financial liabilities at fair value through profit or loss -

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for repurchasing in the near term. This category also includes derivative financial instruments entered by the Group that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the consolidated statements of profit or loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IFRS 9 are satisfied. The Group has designated financial liabilities for contingent consideration as at fair value through profit or loss.

Financial liabilities at amortized cost (loans and borrowings) -

After initial recognition, interest-bearing loans and borrowing are subsequently measured at amortized cost using the EIR. Gains and losses are recognized in the profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by taking into account any discount or premium on acquisition and fees or costs that are an integral part of the EIR. EIR amortization is included in the “Financial costs” caption in the consolidated statements of profit or loss. This category generally applies to interest-bearing loans and borrowings.

Derecognition -

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the consolidated statements of profit or loss.

F-23

Notes to the consolidated financial statements (continued)

(iii) Offsetting of financial instruments -

Financial assets and financial liabilities are offset, and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

(c) Cash and cash equivalents -

“Cash and cash equivalents” caption presented in the consolidated statements of financial position comprise cash at banks and on hand, and short-term highly liquid deposits with a current maturity and subject to an insignificant risk of changes in value.

For the purpose of the consolidated statements of cash flows, cash and cash equivalents consist of cash and short-term deposits as defined above, net of outstanding bank overdrafts as they are considered an integral part of the Group’s cash management. In addition, the Group has restricted cash. See Note 6.

(d) Inventories -

Inventories are valued at the lower of cost or net realizable value. Cost is determined using the average method.

In the case of finished goods and work in progress, cost includes the cost of materials and direct labor and a portion of indirect manufacturing expenses, excluding borrowing costs.

The current portion of the inventories is determined based on the expected amounts to be processed within the next twelve months. Inventories not expected to be processed within the next twelve months are classified as non-current.

Net realizable value is the estimated selling price in the ordinary course of business, less estimated costs of completion and the estimated costs to make the sale.

Provision (or reversal) for losses on the net realizable value are calculated based on a specific analysis conducted annually by Management and is charged to profit or loss in the period in which it determines the need for the provision (or reversal).

Any provision for obsolescence of spare parts and supplies is determined by reference to specific items of stock based on inventory turnover level. A regular review is undertaken to determine the extent of any provision for obsolescence.

(e) Business combinations and goodwill -

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred measured at acquisition date fair value and the amount of any non-controlling interest in the acquiree. For each business combination, the Group elects whether to measure the non-controlling interests in the acquiree at fair value or at the proportionate share of the acquiree’s identifiable net assets. Acquisition-related costs are expensed as incurred and included in “Administrative expenses” caption.

When the Group acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances and pertinent conditions as at the acquisition date. This includes the separation of embedded derivatives in host contracts by the acquiror.

Any contingent consideration to be transferred by the acquirer will be recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IFRS 9 Financial Instruments, is measured at fair value, with changes in fair value recognized in either profit or loss or as a change to other comprehensive income. If the contingent consideration is not within the scope of IFRS 9, it is measured at fair value at the reporting date with changes in the fair value recorded in the consolidated statement of profit or loss.

F-24

Notes to the consolidated financial statements (continued)

Goodwill is initially measured at cost, being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interests, and any previous interests held, over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, the Group re-assesses whether it has correctly identified all of the assets acquired and all of the liabilities assumed and reviews the procedures used to measure the amounts to be recognized at the acquisition date. If the re-assessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain is recognized in the consolidated statements of profit or loss.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, this difference is allocated to each of the Group’s cash-generating units that are expected to benefit from the combination, irrespective of whether other assets or liabilities, of the acquiree, are assigned to those units.

Where goodwill has been allocated to a cash-generating unit and part of the operation within that unit is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed of in these circumstances is measured based on the relative values of the disposed operation and the portion of the cash-generating unit retained.

(f) Investments in associates and joint venture -

An associate is an entity over which the Group has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee, but not control over those policies.

A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control.

The considerations made in determining significant influence or joint control are similar to those necessary to determine control over subsidiaries. The Group’s investments in associates and joint ventures are accounted for using the equity method. Under this method, the investment in an associate or joint venture is initially recognized at cost.

The carrying amount of the investment is adjusted to recognize changes in the Group’s share of net assets of the associate and joint ventures since the acquisition date. Goodwill relating to the associate is included in the carrying amount of the investment and is not tested for impairment individually.

The consolidated statement of profit or loss reflects the Group’s share of the results of operations of the associates and joint ventures. Any change in OCI of those investees is presented, as part of the Group’s other comprehensive income. In addition, when there has been a change recognized directly in the equity of the associate or joint venture, the Group recognizes its share of any changes, when applicable, in the consolidated statements of changes in shareholders’ equity. Unrealized gains and losses resulting from transactions between the Group and the associate or joint venture are eliminated to the extent of the interest in the associate or joint venture.

The aggregate of the Group´s share of profit or loss of an associate or joint venture is shown on the face of the consolidated statements of profit or loss outside operating profit and represents profit or loss after tax in the associates and joint ventures.

The financial statements of the associates or joint venture are prepared for the same reporting period as the Group. When necessary, adjustments are made to bring the accounting policies in line with those of the Group.

After the application of the equity method, the Group determines whether it is necessary to recognize an impairment loss of its investment in associates or joint venture. At each reporting date, the Group determines whether there is objective evidence that the investments in the associates and joint ventures are impaired. If there is such evidence, the Group

F-25

Notes to the consolidated financial statements (continued)

calculates the amount of impairment as the difference between the recoverable amount of the associate and it carrying value, and then recognizes the loss in the consolidated statements of profit or loss.

Upon loss of significant influence over the associate or joint venture, the Group measures and recognizes any retained investment at its fair value. Any difference between the carrying amount of the associate and joint ventures upon loss of significant influence and the fair value of the retained investment and proceeds from disposal is recognized in consolidated statements of profit or loss.

(g) Prepaid expenses -

Non-monetary assets, which represent an entity’s right to receive goods or services, are presented as prepaid expenses. The asset is subsequently derecognized when the goods are received, and the services are rendered.

(h) Property, plant and equipment -

Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any.

The initial cost of an asset comprises its purchase price or construction cost, any costs directly attributable to bringing the asset into operation, the initial estimate of the obligation for mine closing and, borrowing costs for qualifying assets.

When significant parts of property, plant and equipment are required to be replaced at intervals, the Group depreciates them separately based on their specific useful lives. In addition, when a major inspection is performed, its cost is recognized in the carrying amount of plant and equipment as a replacement if the recognition criteria are satisfied. All other maintenance and repair costs are recognized in the consolidated statement of profit or loss as incurred.

Depreciation -

Unit-of-production method:

In mining units with long useful lives, depreciation of assets directly related to the operation of the mine is calculated using the units-of-production method, which is based on economically recoverable reserves of the mining unit. Other assets related to these mining units are depreciated using the straight-line method with the lives detailed in the next paragraph.

Straight-line method:

Depreciation of assets in mining units with short useful lives or used for administrative purposes is calculated using the straight-line method of accounting. The useful lives are the following:

	Years
Buildings, construction and other	2 to 11
Machinery and equipment	5 to 10
Transportation units	5
Furniture and fixtures	5 to 10
Computer equipment	3 to 4

The residual values, useful lives and methods of depreciation of property, plant and equipment are reviewed at each financial year-end, and adjusted prospectively, if appropriate.

Disposal of assets -

An item of property, plant and equipment and any significant part initially recognized is derecognized upon disposal, or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the consolidated statements of profit or loss when the asset is derecognized.

F-26

Notes to the consolidated financial statements (continued)

(i) Leases -

The Group assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period in exchange for consideration.

Group as a lessee -

The Group applies a single recognition and measurement approach for all leases, except for short-term leases with no renewal options and leases of low-value assets. The Group recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets.

i) Right-of-use assets -

The Group recognizes right-of-use assets at the commencement date of the lease. Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the related assets.

If ownership of the leased asset transfers to the Group at the end of the lease term or the cost reflects the exercise of a purchase option, depreciation is calculated using the estimated useful life of the asset.

ii)Lease liabilities –

At the commencement date of the lease, the Group recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Group and payments of penalties for terminating the lease, if the lease term reflects the Group exercising the option to terminate.

Variable lease payments that do not depend on an index or a rate are recognized as expenses (unless they are incurred to produce inventories) in the period in which the event or condition that triggers the payment occurs. The Group does not have variable lease payments that depend on an index or a rate.

In calculating the present value of lease payments, the Group uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the lease payments or a change in the assessment of an option to purchase the underlying asset.

The Group’s lease liabilities are included in the “Financial obligation” caption on the consolidated statements of financial position.

iii)Short-term leases and leases of low-value assets -

The Group applies the short-term lease recognition exemption to its short-term leases of machinery and equipment without renewal option. It also applies the lease of low-value assets recognition exemption to leases of office equipment, which are considered low value. Lease payments on short-term leases and leases of low value assets are recognized as expense on a straight-line basis over the lease term.

F-27

Notes to the consolidated financial statements (continued)

Group as a lessor -

Leases in which the Group does not transfer substantially all the risks and rewards incidental to ownership of an asset are classified as operating leases. Rental income arising is accounted for on a straight-line basis over the lease terms and is included in “Other, net” in the consolidated statement of profit or loss due to its operating nature. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset and recognized over the lease term on the same basis as rental income. Contingent rents are recognized as revenue in the period in which they are earned.

(j) Mining concessions -

Mining concessions represent ownership of the right of exploration and exploitation to the Group on mining properties that contains ore reserves acquired. Mining concessions are irrevocable, provided the holder of a mining concession complies with the obligations set forth in the General Mining Law. Such concessions have an indefinite term, subject to payment of an annual concession fee per hectare granted and achievement of minimum annual production for each hectare. Mining concessions are stated at cost and are amortized using a units of production method, based on proven and probable reserves. If the Group leaves these concessions, the costs associated are written off in the consolidated statements of profit or loss.

Cost includes the fair value attributable to mineral reserves and the portion of mineral resources considered probable of economic extraction at the time of a business combination.

At year-end, the Group evaluates if there is any indicator of impairment. If any indicator exists, the Group estimates the mining concession’s recoverable amount.

Mining concessions are presented in the caption of “Mining concessions, development costs, right-of-use asset, property, plant and equipment, net” in the consolidated statements of financial position.

(k) Exploration and mine development costs –

Exploration costs -

Exploration costs are expensed as incurred. These costs primarily include materials and fuels used, surveying costs, drilling costs and payments made to the contractors.

Exploration and evaluation activity includes:

- Researching and analyzing historical exploration data.

- Gathering exploration data through geophysical studies.

- Exploratory drilling and sampling.

- Determining and examining the volume and grade of the resource.

- Surveying transportation and infrastructure requirements.

- Conducting market and finance studies.

Development costs –

When the Group’s Management approves the feasibility of the conceptual study of a project, the costs incurred to develop such property, including additional costs to delineate the ore body and remove impurities it contains, are capitalized as development costs and included in the “Mining concessions, development costs, right-of-use asset, property, plant and equipment, net” caption in the consolidated statements of financial position. These costs are amortized when production begins, on the units-of-production basis over the proven and probable reserves.

The development costs include:

- Metallurgical and engineering studies.

- Drilling and other costs necessary to delineate ore body.

F-28

Notes to the consolidated financial statements (continued)

- Removal of the initial clearing related to an ore body.

Development costs necessary to maintain production are expensed as incurred.

(l) Stripping (waste removal) costs -

As part of its mining operations, the Group incurs waste removal costs (stripping costs) during the development and production phases of its mining operations. Stripping costs incurred in the development phase of a mine, before the production phase commences (development stripping), are capitalized as part of the cost of constructing the mine and subsequently amortized over its useful life using the units of production method. The capitalization of development stripping costs ceases when the mine starts production.

Stripping costs incurred during the production phase (production stripping costs) are generally considered to create two benefits, being either the production of inventory or improved access to the ore to be mined in the future. Where the benefits are realized in the form of inventory produced in the period, the production stripping costs are accounted for as part of the cost of producing those inventories. Where the benefits are realized in the form of improved access to ore to be mined in the future, the costs are recognized as a non-current asset, referred to as a stripping activity asset, if the following criteria are met:

- Future economic benefits are probable.

- The component of the ore body for which access will be improved can be accurately identified.

- The costs associated with the improved access can be reliably measured.

To identify components of mineral deposit, the Group works closely with the operating personnel to analyze the mine plans. Mostly, an ore body can have several components. The mine plans, and therefore, the identification of components, will vary among mines for several reasons.

The stripping activity asset is initially measured at cost, which is the accumulation of costs directly incurred to perform the stripping activity. The production stripping cost is presented within “Mining concessions, development costs, right-of-use asset, property, plant and equipment, net” caption in the consolidated statements of financial position.

The production stripping cost is subsequently depreciated using the units of production method over the expected useful life of the portion of the ore body that has been made more accessible by the activity. This production stripping cost is stated at cost, less accumulated depreciation and accumulated impairment losses, if any.

(m) Investment properties -

Investment properties are measured at cost, net of accumulated depreciation and impairment loss, if any. Depreciation of the investment properties is determined using the straight-line method with a useful life of 20 years.

Investment properties are derecognized when either they have been disposed of or when they are permanently withdrawn from use and no future economic benefit is expected from their disposal. The difference between the net disposal proceeds and the carrying amount of the asset is recognized in profit or loss in the period of derecognition. The amount of consideration to be included in the gain or loss arising from derecognition of investment property is determined in accordance with the requirements for determining the transaction price in IFRS 15.

Transfers are made to (or from) investment property only when there is a change in use. For a transfer from investment property to an item of property, plant and equipment, the deemed cost for subsequent accounting is the fair value at the date of change in use. If an item of property, plant and equipment becomes an investment property, the Group accounts for such property in accordance with the policy stated under property, plant and equipment up to the date of change in use.

F-29

Notes to the consolidated financial statements (continued)

(n) Impairment of non-financial assets -

The Group assesses, at each reporting date, whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing for an asset is required, the Group estimates the asset’s recoverable amount. An asset’s recoverable amount is the higher of (i) an asset’s or cash-generating unit’s (CGU) fair value less costs of disposal and (ii) its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

In assessing value in use, the estimated future cash flows are discounted to their present value using a post-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less cost of disposal, recent market transactions are taken into account. If no such transactions can be identified, an appropriate valuation model is used.

The Group bases its impairment calculation on detailed budgets and forecast calculations, which are prepared separately for each of the Group’s CGUs to which the individual assets are allocated. These budgets and forecast calculations generally cover a period of five years. A long-term growth rate is calculated and applied to project future cash flows limited to the life of the mine.

Impairment losses of continuing operations, including impairment of inventories, are recognized in the consolidated statements of profit or loss in expense categories consistent with the function of the impaired asset.

For non-financial assets, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses may no longer exist or have decreased. If such indication exists, the Group estimates the asset’s or CGU’s recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset or CGU’s recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the consolidated statements of profit or loss.

(o) Provisions -

General -

Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as a finance cost.

Provision for closure of mining units -

The Group records a provision for closure of mining units when a legally enforceable obligation arises, which is independent of the full depletion of the mine reserves.

The Group recognizes a provision for closure of mining units once the obligation has been properly measured. The liability is initially recognized at the present value of the estimated costs and is capitalized as part of the carrying amount of the related mining assets (property, plant and equipment). The discounted liability is increased for the change in present value based on discounted rates that reflects current market assessments and the risks specify to the liability. In addition, the capitalized cost is depreciated and/or amortized based on the useful life of the asset. Any gain or loss resulting from the settlement of the obligation is recorded in the current results.

Changes in the estimated timing of closure or changes to the estimated future costs are dealt with prospectively by recognizing an adjustment to the provision for closure and a corresponding adjustment to the related mining asset. Any reduction in the provision for closure and, therefore, any deduction from the mining asset to which it relates, may not

F-30

Notes to the consolidated financial statements (continued)

exceed the carrying amount of the mining asset. If it does, any excess over the carrying amount is recognized immediately to the consolidated statements of profit or loss.

If the change in estimate results in an increase in the provision for closure and, therefore, an addition to the carrying value of the mining asset, the Group considers whether this is an indication of impairment of the asset as a whole, and if so, the Group performs an impairment test.

For closed mines, changes to estimated costs are immediately recognized in the consolidated statements of profit or loss.

(p) Treasury shares -

The Group´s own equity instruments that are reacquired (treasury shares) are recognized at cost and deducted from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of the Group’s own equity instruments. Any difference between the carrying amount and the consideration, if reissued, is recognized as additional capital in equity. The voting rights related to treasury shares are cancelled for the Group and no dividends on such shares are allocated.

(q) Revenue recognition -

Revenue from contracts with customers is recognized when control of goods or services are transferred to the customer at an amount that reflects the consideration to which the Group expects to be entitled in exchange for those goods and services.

The Group has concluded that it is the principal in its revenue contracts because it typically controls the goods before transferring them to the customer.

The disclosures of significant accounting judgments, estimates and assumptions relating to revenue from contracts with customers are provided in Note 3.

Sales of goods (concentrates and metals) -

The Group recognizes revenue from sale of concentrates and metals at the point in time when control of the asset is transferred to the customer. Transfer of control is determined in accordance with the terms of each of the contracts entered with the Group’s customers; however, under such contracts, transfer of control generally occurs upon shipment or delivery of the goods, including transportation. The recognized revenue corresponds to an amount that reflects the consideration the Group expects to receive in exchange for those products.

Revenue from sale of concentrates and metals is recorded net of “Commercial deductions”. Commercial deductions correspond to adjustments in price for treatment and refining charges and can include certain penalties that, in accordance with the applicable contract, are deducted from the international fine metal spot price, and that are incurred after the time of sale of the applicable concentrate. The Group deems these deductions to be part of the transaction price. The normal credit term is 30 to 90 days after delivery.

The Group considers whether there are other promises in the contract that are separate performance obligations, to which a portion of the transaction price needs to be allocated. The Group considers that the only performance obligation is the delivery of the goods. In determining the transaction price for the sale of concentrates and metals, the Group considers the effect of variable consideration and the existence of significant financing components.

Variable consideration -

If the consideration in the contract includes a variable amount, the Group estimates the amount of consideration to which it will be entitled in exchange for transferring the goods to the customer. The variable consideration is estimated at contract inception and constrained until it is highly probable that a significant revenue reversal for revenue recognized will not occur when the associated uncertainty with the variable consideration is subsequently resolved.

F-31

Notes to the consolidated financial statements (continued)

The Group´s sales of concentrates and metals allow for price adjustments based on the market price at the end of the relevant quotation period (QP) stipulated in the contract. These are referred as to provisional pricing arrangements and are such that the selling price for metal in concentrate is based on prevailing spot prices on a specified future date after shipment to the customer. Adjustments to the sales price occur based on movements in quoted market prices up to the end of the QP. The period between provisional invoicing and the end of the QP can generally range between one and four months.

The Group's sales of concentrates and metals are also subject to slight variations in yield that can occur while such goods are in transit to their destination due to variations in humidity, weight and ore grades. Such variations are recognized directly as part of "Sales of goods" caption within the statements of profit or loss once the Group reaches an agreement with the applicable customer in respect of final amounts sold.

Sales of concentrates and metals at provisional prices include a gain (loss) to be received at the end of QP; this is considered a variable consideration. Changes in the price during the quotation period are recognized in the “Sales of goods” caption of the statements of profit or loss as "fair value of accounts receivables". See note 20(b).

For provisional pricing arrangements, any future change that occurs over the QP are embedded within the provisional price trade receivables and are, therefore, within the scope of IFRS 9 and not within the scope of IFRS 15. Given the exposure to the commodity price, these provisionally priced trade receivables will fail the cashflow characteristics test within IFRS 9 and will be required to be measured at fair value through profit or loss from initial recognition and until the date of settlement. The subsequent changes in fair value are recognized in the consolidated statements of profit or loss for each period and presented separately from revenue from contracts with customer as part of “fair value of trade receivables”. See note 20(b). Changes in fair value over, and until the end of, the QP, are estimated by reference to updated forward market prices for gold and copper as well as taking into account relevant other fair value considerations set out in IFRS 13, including interest rate and credit risk adjustments.

Sales of services –

Services are recognized over time because the customer simultaneously receives and consumes the benefits provided by the Group. The Group uses the output method for measuring progress of the services as the Group has the right to invoice an amount that corresponds directly to the performance completed to date.

Significant financing components

The Group receives short-term advances from its customers. Using the practical expedient in IFRS 15, the Group does not adjust the promised amount of consideration for the effects of a significant financing component if it expects, at contract inception, that the period between the transfer of the promised good to the customer and when the customer pays for that good will be one year or less.

Contract Balances -

Contract assets

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Group performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognized for the earned consideration that is conditional. As of December 31, 2021 and 2020, the Group has no contractual assets.

Trade receivables

A receivable represents the Group´s right to an amount of consideration that is unconditional.

Contract liabilities

A contract liability is the obligation to transfer goods or services to a customer for which the Group has received consideration (or an amount of consideration is due) from the customer. If customer pays consideration before the Group transfers the goods or services to the customer, a contract liability is recognized when the payment is made or the

F-32

Notes to the consolidated financial statements (continued)

payment is due (whichever is earlier). Contract liabilities are recognized as revenue when the Group performs under the contract. As of December 31, 2021 and 2020, the Group has no contractual liabilities.

Cost to obtain a contract

The Group pays sales commissions as part of the sales of services in the insurance brokerage segment. The Group has elected to apply the optional practical expedient for cost to obtain a contract which allows the Group to immediately expense sales commissions because the amortization period of the assets that the Group otherwise would have used is one year or less.

Interest income -

For all financial instruments measured at amortized cost, interest income is recorded using the EIR. EIR is the rate that exactly discounts the estimated future cash payments or receipts over the expected life of the financial instrument or a shorter period, where appropriate, to the net carrying amount of the financial asset or liability. Interest income is included in finance income in the consolidated statements of profit or loss.

Royalty income -

The royalty income is recognized when the later of the following events occurs: the subsequent sales occur or the performance obligation is satisfied (or partially satisfied).

Dividends -

Dividends from investments is recognized when the Group's right to receive the payment is established, which is generally, when the investments’ shareholders approve the dividend.

Rental income -

Rental income arising from operating leases on investment properties is accounted for on a straight-line basis over the lease term and is included in “Other, net” in the consolidated statement of profit or loss due to its operating nature.

(r) Benefits to employees -

Salaries and wages, bonuses and vacations are calculated in accordance with IAS 19 -Employee Benefits and are calculated in accordance with current Peruvian legislation on an accrual basis.

Workers’ profit sharing -

The Group recognizes workers’ profit sharing in accordance with IAS 19. Workers' profit sharing is calculated in accordance with the Peruvian law (Legislative Decree No. 892), and the applicable rate is 8% over the taxable net base for current year. According to Peruvian law, the limit in the workers' profit sharing that an employee can receive is equivalent to 18 months of wages, and any excess above such limit has be transferred to the Regional Government and “National Fund for Employment’s Promotion and Training” (“FONDOEMPLEO”).

(s) Borrowing costs -

Costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as part of the cost of an asset. The Group defines a qualifying asset as one which value is greater than US$5 million and requires a period greater than 12 months to get it ready for its intended use. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that the Group incurs in connection with the borrowing of funds.

(t) Taxes -

Current income tax -

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the tax authority. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted, at the reporting period.

F-33

Notes to the consolidated financial statements (continued)

Current income tax relating to items recognized directly in equity is recognized in equity and not in the consolidated statements of profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred income tax -

Deferred income tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred income tax liabilities are recognized for all taxable temporary differences, except for taxable temporary differences associated with investments in associates, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred income tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized.

The carrying amount of deferred tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates and tax laws that have been enacted or substantively enacted at the reporting date.

Deferred tax items are recognized in correlation to the underlying transaction either in profit and loss, OCI or directly in equity.

Deferred tax assets and deferred tax liabilities are offset if a legally enforceable right to compensate current tax assets against current income tax liabilities and the deferred taxes relate to the same taxable entity and the same taxation authority.

Uncertain tax positions -

The Group determines whether to consider each uncertain tax position separately or together with one or more other uncertain tax positions and uses the approach that better predicts the resolution of the uncertainty. The Group determines, based on its tax compliance and transfer pricing studies whether or not it is probable that its tax positions (including those for the subsidiaries) would be accepted by the tax authorities.

Peruvian mining royalties and special mining tax -

In accordance with Law No.28258, as amended by Law No. 29788, mining royalties are either payable as the higher of (i) a specified percentage of operating profit or (ii) 1% of revenues. If the mining royalty is calculated as a percentage of operating profit, marginal rates ranging from 1% to 12% that increase progressively for companies with higher operating margins will apply.

Mining royalties and the special mining tax are accounted for in accordance with IAS 12 - Income Taxes because they have the characteristics of an income tax. This is considered to be the case when they are imposed under government authority and the amount payable is based on taxable income-rather than physical quantities produced or as a percentage of revenue-after adjustment for temporary differences. Legal rules and rates used to calculate the amounts payable are those in effect on the date of the consolidated statements of financial position.

F-34

Notes to the consolidated financial statements (continued)

Therefore, obligations arising from Mining Royalties and the Special Mining Tax are recognized as income tax under the scope of IAS 12. Both Mining Royalties and Special Mining Tax generated deferred tax assets and liabilities, which must be measured using the average rates expected to apply to operating profit in the quarter in which the Group expects the temporary differences will reverse.

Sales tax -

Expenses and assets are recognized net of the amount of sales tax, except:

(i) When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable;

(ii) When receivables and payables are stated with the amount of sales tax included.

The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the consolidated statements of financial position.

(u) Fair value measurement

The Group measures its financial instruments at fair value at the date of the consolidated statements of financial position. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

- In the principal market for the asset or liability, or

- In the absence of a principal market, in the most advantageous market for the asset or liability.

The Group uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

- Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

- Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.

- Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are recognized in the consolidated financial statements on a recurring basis, the Group determines whether transfers have occurred between levels in the hierarchy by reassessing categorization (based on the lowest-level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

The Group's management determines the policies and procedures for both recurring fair value measurement and non-recurring measurement. At each reporting date, the Group's management analyzes the movements in the values of assets and liabilities, which are required to be re-measured or re-assessed as per the Group’s accounting policies.

For the purpose of fair value disclosures, the Group has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

F-35

Notes to the consolidated financial statements (continued)

(v) Derivative financial instruments and hedge accounting -

Initial recognition and subsequent measurement -

The Group uses derivative instruments to hedge its commodity price risk (forward commodity contracts ) and interest rate risk. Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently re-measured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

At the inception of the hedge relationship, the Group formally designates and documents the hedge relationship to which it wishes to apply hedge accounting and the risk management objective and strategy for undertaking the hedge.

The documentation includes identification of the hedging instrument, the hedged item, the nature of the risk being hedged and how the Group will assess whether the hedging relationship meets the hedge effectiveness requirements (including the analysis of sources of hedge ineffectiveness and how the hedge ratio is determined). A hedging relationship qualifies for hedge accounting if it meets all the following effectiveness requirements:

- There is ‘an economic relationship’ between the hedged item and the hedging instrument.

- The effect of credit risk does not ‘dominate the value changes’ that result from that economic relationship.

- The hedge ratio of the hedging relationship is the same as that resulting from the quantity of the hedged item that the Group hedges and the quantity of the hedging instrument that the Group actually uses to hedge that quantity of hedged item.

The Group’s hedges are classified as cash flow hedges. The effective portion of gain or loss on the hedging instrument is initially recognized in the consolidated statements of changes in equity, under the “Other comprehensive income (loss)” caption, while the ineffective portion is recognized immediately in the consolidated statements of profit or loss in the “Finance costs” caption.

(w) Discontinued operations -

Discontinued operations are excluded from the results of continuing operations and are presented as a single amount as profit or loss after tax from discontinued operations in the consolidated statement of profit or loss.

Additional disclosures are provided in note 1(e). All other notes to the consolidated financial statements include amounts for continuing operations, unless otherwise mentioned.

(x) Other assets -

The "Other assets" caption includes patents and industrial property, right-of-use assets related to rights of way, and software licenses. Patents and industrial property and right-of-use assets are amortized over their useful economic lives. Software licenses are amortized using the straight-line method over useful lives of 1 to 10 years.

The useful lives of intangible assets are assessed as either finite or indefinite. Intangible assets with finite live are amortized over their useful economic useful lives and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of profit or loss in the expense category that is consistent with the function of the intangible assets.

Internally generated intangibles, excluding capitalized development costs, are not capitalized. Instead, the related expenditure is recognized in the consolidated statement of profit or loss in the period in which the expenditure is incurred.

F-36

Notes to the consolidated financial statements (continued)

Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the consolidated statement of profit or loss when the asset is derecognized.

3.    Significant judgments, estimates and assumptions

The preparation of the Group’s consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. The estimates and assumptions are continuously evaluated and based on management´s experience and other facts, including the expectations about future events, which are reasonable under the current situation. Uncertainty about these estimates and assumptions could result in outcomes that require material adjustment to the carrying amount of assets and liabilities affected in future periods. Further information on each of these areas and how they affect the various accounting policies are described below and in the relevant notes to the consolidated financial statements.

3.1.  Judgments

In the process of applying the Group’s accounting policies, Management has made the following judgments, which have the most significant effect on the amounts recognized in the consolidated financial statements:

(a) Contingencies and uncertain tax positions-

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential impact of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

(b) Development start date -

The Group assesses the status of each exploration project of its mining units to determine when the development phase begins. One of the criteria used to evaluate the development start date is when the Group determines that the property can be economically developed.

(c) Production start date -

The Group assesses the stage of each mine under development to determine when a mine moves into the production phase. The criteria used to assess the start date are determined based on the unique nature of each mining project, such as the complexity of the project and its location. The Group considers various relevant criteria to assess when the production phase is considered to have commenced. Some of the criteria used to identify the production start date include, but are not limited to:

- Level of capital expenditure incurred compared to the original construction cost estimates.

- Completion of a reasonable period of testing of the mine plant and equipment.

- Ability to produce minerals in saleable form (within specifications).

- Ability to sustain ongoing production of minerals.

When a mine development /construction project moves into the production phase, the capitalization of certain mine development costs cease and costs are either regarded as forming part of the cost of inventory or expensed, except for costs that qualify for capitalization relating to mining asset additions or improvements. It is also at this point that depreciation or amortization commences.

F-37

Notes to the consolidated financial statements (continued)

(d) Useful life of property, plant and equipment

Depreciation is calculated under the straight-line method of accounting considering the lower of estimated useful lives of the assets or estimated reserves of the mining unit. See note 2.4(h) for useful lives.

(e) Revenue from contracts with customers -

The Group applies judgement for determining the timing of satisfaction of services of revenue from contracts with customers. The Group has concluded that revenue related to services such as energy generation and transmission, industrial services, and other services is to be recognized over time because the customer simultaneously receives and consumes the benefits provided by the Group.

The Group has determined that the output method is the best method in measuring progress of the services mentioned above due to the Group has the right to invoice an amount that corresponds directly to the performance completed to date.

3.2.        Estimates and assumptions

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Group based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may vary due to market changes or circumstances arising beyond the control of the Group. Such changes are reflected in the assumptions when they occur.

(a) Determination of mineral reserves and resources -

Recoverable proven and probable reserves and resources are the part of a mineral deposit than can be economically and legally extracted or produced at the time of the reserve and resources determination. The determination of reserves involves numerous uncertainties with respect to the ultimate geology of the ore bodies, including quantities, grades and recovery rates. Estimating the quantity and grade of reserves and resources requires the Group to determine the size, shape and depth of its ore bodies by analyzing geological data, such as sampling of drill holes, tunnels and other underground workings. In addition to the geology of the Group’s mines, assumptions are required to determine the economic feasibility of mining these reserves, including estimates of future commodity prices and demand, the mining methods the Group uses and the related cost incurred to develop and mine its reserves and resources. The process to estimate proven and probable ore reserves and resources is audited by an independent consultant each year.

All estimated reserves and resources represent estimated quantities of mineral proven and probable that under current conditions can be economically and legally processed. Changes could occur on reserve and resource estimates due to, among others, revisions to the data or geological assumptions, changes in prices, production costs and results of exploration activities. Changes in estimated reserves and resources primarily affect the depreciation of development costs, property, plant and equipment related directly to mining activity, the provision for mine closure, the assessment of the deferred asset’s recoverability and the amortization period for development costs.

(b) Units of production depreciation -

Reserves and resources are used in determining the depreciation and amortization of mine-specific assets.

This results in a depreciation or amortization charge proportional to the depletion of the anticipated remaining life of mine production. Each mine’s life is assessed annually to evaluate: (i) physical life limitations and (ii) present assessments of economically recoverable reserves of the mine property. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes are recorded prospectively.

(c) Provision for closure of mining units -

The Group assesses its provision for closure of mining units at each reporting date using a discounted future cash flow model. In determining the amount of the provision, it is necessary to make significant assumptions and

F-38

Notes to the consolidated financial statements (continued)

estimates, because many factors exist that can affect the final amount of this provision. These factors include estimates of the extent and costs of closure activities, technological changes, regulatory changes, cost increases as compared to the inflation rates, and changes in discount rates and periods such costs where are expected to be incurred. These uncertainties may result in future actual expenditure differing from the amounts currently provided. The provision at the reporting date represents management’s best estimate of the present value of the future closure costs required.

(d) Inventories -

Inventories are classified as current or non-current depending on the length of time that management estimates will be needed to reach the production state of concentrate extraction for each mining unit.

Net realizable value tests are performed at each reporting date and represent the estimated future sales price of the product the entity expects to realize when the product is processed and sold, less estimated costs to complete production and bring the product to sale. Additionally, management considers the time value of money in calculating the net realizable value of its non-current inventories.

Classified minerals, which are materials with metal content that were removed from the pit of the Colquijirca mining unit for treatment at the expansion operation plant, contain lower grade ore than the average of treated minerals and are available to continue in the process of recovery of mineral and concentrates. Because it is generally impracticable to determine the mineral contained in the classified mineral located in the deposit field near Tajo Norte of Colquijirca mining unit by physical count, reasonable estimation methods are employed. The quantity of minerals delivered to classified mineral is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated copper, lead and zinc grades of material delivered to classified minerals.

For minerals outside leach platform inventories, finished and in-progress goods are measured by estimating the number of tons added and removed. The number of contained gold ounces is based on assay data, and the estimated recovery percentage is based on the expected processing method. Tonnages and ounces of mineral are verified by periodic surveys.

For minerals inside leach platform inventories, reasonable estimation methods are employed because it is generally impracticable to determine the mineral contained in leach platforms by physical count. The quantity of material delivered to leach platforms are based on surveyed volumes of mined material and daily production records. Sampling and assaying of blasthole cuttings determine the estimated ore grades of material delivered to leach platforms.

(e) Impairment of non-financial assets -

The Group assesses each asset or cash generating unit in each reporting period to determine whether any indication of impairment exists. Where an indicator of impairment exists, a formal estimate of the recoverable amount is made, which is considered the higher of (i) the fair value less costs of disposal and (ii) value in use. The assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates, operating costs, among others. These estimates and assumptions are subject to risk and uncertainty.

The fair value of mining assets is generally calculated by the present value of future cash flows arising from the continued use of the asset, which include some estimates, such as the cost of future expansion plans, using assumptions that a third party might consider. The future cash flows are discounted to their present value using a discount rate that reflects current market assessment of the value of money over time, as well as specific risks of the asset or cash-generating unit under evaluation. The Group has determined the operations of each mining unit as a single cash generating unit.

Notes to the consolidated financial statements (continued)

(f) Deferred income tax asset and recoverability -

Deferred tax assets are recognized for unused tax losses to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant management judgment is required to determine the amount of deferred tax assets that can be recognized, based upon the likely timing and the level of future taxable profits together with future tax planning strategies.

(g) Fair value of contingent consideration -

The contingent consideration arising from a business combination is measured at fair value at the date of acquisition, as part of the business combination. If the contingent consideration is eligible to be recognized as a financial liability, the fair value is subsequently re-measured at each date of the consolidated financial statements. Determining the fair value of the contingent consideration is based on a model of discounted future cash flows. The key assumptions take into account the likelihood of achieving each goal of financial performance as well as the discount rate.

4.    Standards issued but not effective

Certain new accounting standards and interpretations have been issued that are not yet effective as of December 31, 2021, and have not been early adopted by the Group. These standards are not expected to have a material impact on the Group in the current or future reporting periods and on foreseeable future transactions.

Amendments to IAS 1: Classification of Liabilities as Current or Non-current -

In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classifying liabilities as current or non-current. The amendments clarify:

- What is meant by a right to defer settlement

- That a right to defer must exist at the end of the reporting period

- That classification is unaffected by the likelihood that an entity will exercise its deferral right

- That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification

The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and must be applied retrospectively. The Group is currently assessing the impact the amendments will have on current practice and whether existing loan agreements may require renegotiation.

Reference to the Conceptual Framework – Amendments to IFRS 3 -

In May 2020, the IASB issued Amendments to IFRS 3 Business Combinations - Reference to the Conceptual Framework. The amendments are intended to replace a reference to the Framework for the Preparation and Presentation of Financial Statements, issued in 1989, with a reference to the Conceptual Framework for Financial Reporting issued in March 2018 without significantly changing its requirements.

The Board also added an exception to the recognition principle of IFRS 3 to avoid the issue of potential ‘day 2’ gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 or IFRIC 21 Levies, if incurred separately. At the same time, the Board decided to clarify existing guidance in IFRS 3 for contingent assets that would not be affected by replacing the reference to the Framework for the Preparation and Presentation of Financial Statements. The amendments are effective for annual reporting periods beginning on or after January 1, 2022 and apply prospectively. The Group will apply changes in IFRS 3 prospectively for any business combination.

Notes to the consolidated financial statements (continued)

Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 -

In May 2020, the IASB issued Property, Plant and Equipment — Proceeds before Intended Use, which prohibits entities deducting from the cost of an item of property, plant and equipment, any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss. The amendment is effective for annual reporting periods beginning on or after January 1, 2022 and must be applied retrospectively to items of property, plant and equipment made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment. The amendments are not expected to have a material impact on the Group as it does not generally receive proceeds from selling items while bringing an asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37 –

In May 2020, the IASB issued amendments to IAS 37 to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making. The amendments apply a “directly related cost approach”. The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract. The amendments are effective for annual reporting periods beginning on or after January 1, 2022. The Group evaluated and concluded that there are no changes as a result of the amendments to its existing accounting policies.

IFRS 9 Financial Instruments – Fees in the ’10 per cent’ test for derecognition of financial liabilities -

As part of its 2018-2020 annual improvements to IFRS standards process the IASB issued amendment to

IFRS 9. The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by either the borrower or lender on the other’s behalf. An entity applies the amendment to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment. The amendment is effective for annual reporting periods beginning on or after January 1, 2022 with earlier adoption permitted. The Group evaluated and concluded that there are no changes as a result of the amendments.

Definition of Accounting Estimates - Amendments to IAS 8 -

In February 2021, the IASB issued amendments to IAS 8, in which it introduces a definition of “Accounting

Estimates”. The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and the correction of errors. Also, they clarify how entities use measurement techniques and inputs to develop accounting estimates. The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and apply to changes in accounting policies and changes in accounting estimates that occur on or after the start of that period. Earlier application is permitted as long as this fact is disclosed. The Group will apply changes in IAS 8 prospectively for any business combination.

Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2 -

In February 2021, the IASB issued amendments to IAS 1 and IFRS Practice Statement 2 Making Materiality Judgements, in which it provides guidance and examples to help entities apply materiality judgements to accounting policy disclosures. The amendments aim to help entities provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures. The amendments to IAS 1 are applicable for annual periods beginning on or after January 1, 2023 with earlier application permitted. Since the amendments to the Practice Statement 2 provide non-mandatory guidance on the application of the definition of material to accounting policy information, an effective date for these amendments is not necessary. The Group is currently assessing the impact of the amendments to determine the impact they will have on the Group’s accounting policy disclosures.

Investment in Minera Yanacocha S.R.L.-

The Group, through its subsidiary Compañía Minera Condesa S.A., has an interest of 43.65% of Minera Yanacocha S.R.L. (hereinafter “Yanacocha”). Yanacocha is engaged in gold production and exploration and development of gold and copper in their own concessions or owned by the subsidiary S.M.R.L. Chaupiloma Dos de Cajamarca, which signed a contract of use of mineral rights.

During December 2021, the Company's Management decided to dispose of its investment in Yanacocha, classifying it as held for sale as of December 31, 2021 and as a "Liability directly associated with the held for sale investment in Yanacocha”, see note 1(e), in order to concentrate on its existing asset portfolio, reduce its levels of financial indebtedness and improve the returns of its shareholders.

On February 7, 2022, Buenaventura entered into definitive agreements with Newmont to sell all of the shares it owned in Yanacocha for a consideration collected in full in February 2022 of US$300,000,000, as well as contingent payments linked to the production of the Sulphides Project that Yanacocha plans to develop and future increases in mineral prices, payments that can amount to up to US$100,000,000.

Additionally, the subsidiary Chaupiloma transferred all its mining concessions to Yanacocha, maintaining as consideration for this transfer a royalty equal to the one it currently receives from Yanacocha, as well as two additional royalties on concessions that may house future projects. Similarly, Newmont transferred in favor of Buenaventura its shares in the subsidiary Minera La Zanja S.R.L. (hereinafter “La Zanja”), in exchange for a royalty on the future production of said mining unit. On the other hand, Newmont paid US$45,000,000 to Buenaventura in order to cover part of the future costs of the La Zanja closure plan.

Net cost	1,754,372					1,650,361					1,537,870

(b) Impairment of long-lived assets

In accordance with its accounting policies and processes, each asset or CGU is evaluated annually at year-end, to determine whether there are any indications of impairment. If any such indications of impairment exist, a formal estimate of the recoverable amount is performed.

In assessing whether impairment is required, the carrying value of the asset or CGU is compared with its recoverable amount. The recoverable amount is the higher of (i) the CGU’s fair value less costs of disposal (FVLCD) and (ii) its value in use (VIU). Given the nature of the Group’s activities, information on the fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers or similar transactions are taking place. Consequently, the recoverable amount for each CGU is estimated based on discounted future estimated cash flows expected to be generated from the continued use of the CGUs using market-based commodity price and exchange assumptions, estimated quantities of recoverable minerals, production levels, operating costs and capital requirements, and its eventual disposal, based on the latest life of mine (LOM) plans. Capital and operating expenditure associated with our climate change initiatives are, to the extent necessary, taken into account when determining the recoverable amount of each CGU. The Group's environmental management follows industry best practices, seeking to innovate in water management and mine closure, looking forward to supporting the sustainability of operations. The use of clean technologies to reduce fresh water consumption and waste generation, together with the application of adequate environmental protection standards and procedures in the management of operations are essential for Buenaventura. The challenges that come from higher environmental and social expectations of the environment are being addressed appropriately, encouraging research to improve the prevention and control of the environmental impacts of our activities.

These cash flows were discounted using a real post-tax discount rate that reflected current market assessments of the time value of money and the risks specific to the CGU.

F-54

Notes to the consolidated financial statements (continued)

The estimates of quantities of recoverable minerals, production levels, operating costs and capital requirements are obtained from the planning process, including the LOM plans, one-year budgets and CGU-specific studies.

During 2021, the Group identified impairment indicators in Orcopampa, Uchucchacua, La Zanja and Río Seco. The Group evaluated and concluded that there is no impairment as a result of the analysis of the recoverable amount of said units based on their value in use for Orcopampa, Uchucchacua, and La Zanja. As a result of the analysis of the recoverable amount as of December 31, 2021 in Río Seco (which receives raw materials from Uchucchacua mining unit), the Group recognized an impairment of assets for US$19.9 million given the suspension of operations during 2021 and until the start of operations of the Uchuchacua mining unit. In addition, the La Zanja mining recognized a reversal of impairment of US$5.0 million, the main factors considered in the impairment reversal analysis were increase of prices and operation cost reduction.

During 2020, the Group identified impairment indicators in its Julcani, Orcopampa, Uchucchacua, El Brocal and La Zanja. The Group evaluated and concluded that there is no impairment as a result of the analysis of the recoverable amount of said units based on their value in use. The main factors considered in the impairment analysis were reserves, prices and mining useful lives. As a result of the analysis of the recoverable amount as of December 31, 2020, Buenaventura recognized a reversal for impairment of long-lived assets for US$2.1 million derived from the evaluation of its Julcani mining unit ( recognized a provision for impairment for US$2.1 million as of December 31, 2019). The main factors considered in the impairment analysis were the increase in metal price projections and the life of mine plans. The recoverable amounts of the Julcani mining unit are based on management’s estimations of the value in use.

During 2019, as a result of the analysis of the recoverable amount, The Group did not recognize an impairment or reversal of long-lived assets.

Key assumptions

The determination of value in use is most sensitive to the following key assumptions:

- Production volumes

- Commodity prices

- Discount rate

- Residual value

Production volumes: Estimated production volumes are based on detailed life-of-mine plans and take into account development plans for the mines agreed by management as part of planning process. Production volumes are dependent on a number of variables, such as: the recoverable quantities; the production profile; the cost of the development of the infrastructure necessary to extract the reserves; the production costs; the contractual duration of mining rights; and the selling price of the commodities extracted.

As each producing mining unit has specific reserve characteristics and economic circumstances, the cash flows of the mines are computed using appropriate individual economic models and key assumptions established by management. The production profiles used were consistent with the reserves and resource volumes approved as part of the Group’s process for the estimation of proved and probable reserves and resource estimates.

Commodity prices: Forecast commodity prices are based on management’s estimates and are derived from forward price curves and long-term views of global supply and demand, building on experience of the industry and consistent with external sources. These prices were adjusted to arrive at appropriate consistent price assumptions for the different qualities and type of commodities, or, where appropriate, contracted prices were applied. These prices are reviewed at least annually.

Notes to the consolidated financial statements (continued)

Estimates prices for the current and long-term periods that have been used to estimate future cash flows are as follows:

Silver	23.00/Oz	21.20/Oz
Copper	7,250/TM	7,083/TM
Lead	1,850/TM	2,056/TM

Discount rate: In calculating the value in use, as of December 31, 2021 a discount rate after tax of 6.04%, 7.01% and 7.86% (equivalent to pre-tax rate of 9.31%, 10.81% and 12.12%) were applied to the post-tax cash flows of Buenaventura, La Zanja and Río Seco, respectively. In calculating the value in use, as of December 31, 2020, a discount rate after tax of 5.25%, 7.91% and 5.96% (equivalent to pre-tax rate of 8.09%, 12.18% and 9.19%) were applied to the post-tax cash flows of Buenaventura, El Brocal and La Zanja, respectively. These discount rates are derived from the Group’s post-tax weighted average cost of capital (WACC), with appropriate adjustments made to reflect the risks specific to the CGU. The WACC takes into account both debt and equity. The cost of equity is derived from the expected return on investment by the Group’s investors. The cost of debt is based on its interest-bearing borrowings the Group is obliged to service. The Beta factors are evaluated annually based on publicly available market data.

(c) The book value of assets held under finance leases, and assets under trustworthy equity, amounted to US$270.8 million as of December 31, 2021 (US$187.8 million as of December 31, 2020) and is presented in various items of property, plant and equipment. During 2021 and 2020, no acquisitions of assets under lease agreements were made. Leased assets are pledged as security for the related finance lease liabilities.

(d) During 2021, 2020 and 2019, no borrowing costs were capitalized.

(e) Right-of-use assets

The net assets for right-of-use assets maintained by the Group correspond to the following:

Notes to the consolidated financial statements (continued)

During 2021, the additions to the right-of-use assets were US$3.0 million and no disposals were made (additions of US$6.2 million and disposals for US$1.3 million during 2020).

(f) Mining concessions includes goodwill of El Brocal for an amount to US$34.0 million.

(g) During June 2021, as a result of the reserves review, the subsidiary El Brocal wrote off the phase 6 for a total of 1,181,280 DMT at a value of US$6,763,000. The write-off corresponds to a new estimation of reserves of the superficial operation as a result of the topographical information. The balance as of December 31, 2021 of this phase is 5,730 DMT valued in US$118,000 which are expected to be produced during 2022.

In December 2020, as a result of the review of the mineral reserve balances, the subsidiary El Brocal wrote off the phase 9 for a total of 1,102,117 DMT at a value of US$11,633,000. The write-off corresponds to a loss of reserves due to variation in technical and economic parameters such as: decrease in estimated prices; increased cut-off; percentage decrease in payable items; and new block model.

The provision for closure of mining units and exploration projects represents the present value of the closure costs that are expected to be incurred between the years 2022 and 2041. The Group recognizes the provision of closure of mining units and explorations projects based on estimates of studies and activities that meet the environmental regulations in effect and that will be approved by the Ministry of Energy and Mines. The Group recognizes the provision of continued operations based on its analysis and estimates prepared by independent advisors and reviewed by the Group´s management. Provisions related to discontinued operations are based on estimates prepared by internal advisors.

The provision for closure of mining units and exploration projects corresponds mostly to activities that must be carried out for restoring the mining units and areas affected by operation and production activities. The principal works to be performed correspond to earthworks, re-vegetation efforts and dismantling of the plants. Closure budgets are reviewed regularly to take into account any significant change in the studies conducted. Nevertheless, the closure costs of mining units will depend on the market prices for the closure works required, which would reflect future economic conditions. Also, the time when the disbursements will be made depends on the useful life of the mine, which will be based on future metals prices.

As of December 31, 2021, the future value of the provision for closure of mining units and exploration projects was US$310.7 million, which has been discounted using annual risk-free rates from minimums of 0.29% to 3.63%, in periods of 1 to 20 years (as of December 31, 2020, the provision was US$277.7 million). The Group believes that this liability is sufficient to meet the current environmental protection laws approved by the Ministry of Energy and Mines.

As of December 31, 2021, the Group has constituted letters of credit in favor of the Ministry of Energy and Mines for US$155.9 million (US$140.0 million as of December 31, 2020) to secure current mine closure plans of its mining units and exploration projects to date.

- Annual interest rate: LIBOR 30 days plus 2.10%.

- Term: 18 months since November 2, 2020, with final maturity in May 2022.

Management performed an analysis to determine if the modification of the terms and conditions in October 2020 were substantially different terms and shall be accounted for as an extinguishment of the original financial liability and the recognition of a new financial liability. The Group concluded that the terms are not substantially different, due to the discounted present value of the cash flows under the new terms, including any fees paid net of any fees received and discounted using the original effective interest rate were less than 10 per cent different compared to the discounted present value of the remaining cash flows of the original financial liability.

19.   Tax situation

(a) Current tax regime -

The Company and its Peruvian subsidiaries are subject to the Peruvian tax regime. By means of Law N° 1261 enacted on December 10, 2016, the Peruvian government introduced certain amendments to the Income Tax Law, effective January 1, 2017. The most relevant are listed below:

- A corporate income tax rate of 29.5% is set.

- A tax of 5% of the income tax is established to the dividends or any other form of distribution of profits. The rate applicable to dividends will be considered taking into account the year in which the results or profits that form part of the distribution has been obtained. The rate will be considered according to the following: 4.1% with respect to the results obtained until December 31, 2014; 6.8% with respect to the results obtained during the years 2015 and 2016; and 5% with respect to the results obtained from January 1, 2017.

- It has been established that the distribution of dividends to be made corresponds to the oldest retained earnings.

In July 2018, Law No. 30823 was published. Under this Law, the Congress delegated to the Executive Power the power to legislate on various issues, including tax and financial matters. In this sense, the main tax regulations issued are the following:

(i) The Tax Code was modified in order to provide greater guarantees to taxpayers in the application of the general anti-avoidance rule (Rule XVI of the Preliminary Title of the Tax Code); as well as to provide the Tax Administration with tools for its effective implementation.

F-73

Notes to the consolidated financial statements (continued)

(ii) Rules were established for the accrual of income and expenses for tax purposes as of January 1, 2019. Until 2018, there was no regulatory definition of this concept, so in many cases the accounting standards for its interpretation.

(iii) Through Legislative Decree No. 1424 published on September 13, 2018, modifications were introduced in the Income Tax Law on the limit on the deduction for interest expenses. Since fiscal year 2021, net interest expenses will not be deductible in the part that exceeds 30% of the fiscal EBITDA of the previous fiscal year. It has been established that the amount of interest expenses that exceeds the amount of interest income, computable to determine net income, is considered net interest. Likewise, fiscal EBITDA is considered to be net income after compensation for losses plus net interest, depreciation and amortization. The net interest that cannot be deducted due to the application of this limit may be added to that corresponding to the four immediately following fiscal years. On December 30, 2021, the regulations were published through Supreme Decree No. 402-2021 establishing, among other points, that, in cases in which the taxpayer does not obtain net income in the taxable year or having obtained it, the amount of the losses of previous years compensable with that were equal to or greater, the tax EBITDA will be equal to the sum of the net interest, depreciation and amortization deducted in said year. As of December 31, 2021, the Group has not generated undeducted interest.

Through Legislative Decree No. 1488, published on May 10, 2020, a special depreciation regime is established, exceptionally and temporarily, for taxpayers of the General Income Tax Regime, the main aspects of which are the following:

- As of fiscal year 2021, buildings and constructions acquired in fiscal years 2020 to 2022, will be depreciated applying an annual percentage of 20% until their total depreciation, provided that the following conditions are met:

(i) Are totally affected by the production of third category taxable income.

(ii) Construction would have started as of January 1, 2020. For these purposes, the beginning of construction is understood to be the moment when the building license or other document established by the Regulation is obtained and in the case of processing plants and other construction of processing concessions, when the construction authorization is obtained.

(iii) Until December 31, 2022, the construction has a work progress of at least 80%. In the case of constructions that have not been completed until December 31, 2022, it is presumed that the work in progress to that date is less than 80%, unless the taxpayer proves otherwise. It is understood that the construction has been completed when the approval of the work or other document established by the Regulation has been obtained from the municipality and in the case of processing plants when the administrative act that approves the verification inspection of the construction of works has been obtained.

-As of fiscal year 2021, assets acquired in fiscal years 2020 to 2021, affected by the production of taxable income, will be depreciated by applying the following annual percentages until they are fully depreciated:

- Data processing equipment: 50%

- Machinery and equipment: 20%

- Land transport vehicle (except railways) with EURO IV, Tier II and EPA 2007 technology, used by authorized companies: 33.3%

- Hybrid or electric land transport vehicle (except railways): 50%.

On December 27, 2021, Law 31380 was published in which Congress delegates to the Executive Branch the power to legislate for a period of 90 days on tax, financial and economic reactivation matters for a period of 90 calendar days.

F-74

Notes to the consolidated financial statements (continued)

In tax matters, these powers refer to the Income Tax regulations on the deductibility of certain types of expenses, non-domiciled income, market value in the transfer of securities, among other issues, as well as the regulations of the Tax Code, Customs and Municipal Taxation.

On March 31, 2020, Superintendence Resolution 066-2020/SUNAT was published, establishing new default interest rates in force as of April 1, 2020. Thus, the default interest rate in national currency went from 1.2% to 1% and in the case of foreign currency it went from 0.6% to 0.5%. Likewise, the interest rates for the return of undue or excessive payments in national currency went from 0.50% to 0.42%, while in foreign currency it went from 0.30% to 0.25%. In the case of the interest for return for withholding and/or perceptions not applied to the IGV, it went from 1.2% to 1%.

Subsequently, on March 31, 2021, Superintendence Resolution 044-2021/SUNAT was published, establishing that the default interest rate in national currency goes from 1.0% to 0.9% per month, effective as of April 1, 2021. The other rates have not changed.

(b) Years open to tax review -

During the four years following the year of filing the tax return, the tax authorities have the power to review and, as applicable, correct the income tax computed by the Group. The Income Tax and Value Added Tax (VAT) returns for the following years are open to review by the Tax Authorities:

	Years open to review by the

Apu Coropuna S.R.L.	2016-2021
Cerro Hablador S. A. C.	2016-2021
Minera Azola S. R. L.	2016-2021

As of the date of issuance of these consolidated financial statements, Buenaventura is being audited by the Tax Administration for income tax for the taxable year of 2017. Likewise, the audit processes of the subsidiaries La Zanja and Compañía Minera Condesa S.A. are being initiated. for the taxable year 2016.

Due to the possible interpretations that the Tax Authorities may give to legislation in effect, it is not possible to determine whether any of the tax audits will result in increased liabilities for the Group. For that reason, any tax or surcharge that could arise from future tax audits would be applied to the income of the period in which it is determined. In management’s opinion and its legal advisors, any possible additional payment of taxes in the entities mentioned before would not have a material effect on the consolidated financial statements as of December 31, 2021 and 2020.

The open tax process of the Group and its associates are described in note 31(d).

F-75

Notes to the consolidated financial statements (continued)

(c) Tax-loss carryforwards -

As of December 2021 and 2020, the tax-loss carryforward determined by the Group amounts to approximately S/3,124,358,000 and S/2,469,226,000, respectively (equivalent to US$781,480,000 and US$681,354,000 respectively). As permitted by the Income Tax Law, the Group has chosen a system that permits to offset these losses against future net taxable income subject to an annual cap equivalent to 50% of net taxable income.

The Group recognized a deferred income tax asset related to the tax-loss carryforward of those entities where it is probable that a carryforward can be used to offset future taxable profits. See note 31.

(d) Transfer pricing - For purposes of determining its income tax, the transfer prices for transactions with related companies and companies domiciled in territories with little or no taxation must be supported with documentation and information on the valuation methods used and the criteria considered for their determination. The tax administration can request this information based on analysis of the Group’s operations. The Group’s management and its legal advisers believe that, as a result of the application of these standards, no material contingencies will arise for the Group as of December 31, 2021, 2020 and 2019.

(b) Contingent consideration -

On August 18, 2014, Buenaventura acquired from Minera Gold Fields Peru S.A. (“Gold Fields”) 51% of the voting shares of Canteras del Hallazgo S.A.C., which represent the whole interest of Gold Fields in the equity of such entity.

Through the merger with Canteras del Hallazgo S.A.C, the Group is the owner of the Chucapaca project, which is located in the Ichuña district, in the General Sanchez Cerro province, in the Moquegua department, Peru. According to previously performed studies, there is evidence of the existence of gold, silver, copper and antimony in the area, specifically in the Canahuire deposit.

F-83

Notes to the consolidated financial statements (continued)

The purchase and sale agreement considered a contingent consideration of US$23,026,000, which corresponds to the present value of the future royalty payments equivalent to 1.5% over the future sales of the minerals arising from the mining properties acquired. The fair value of the future royalty payments was determined using the income approach.

Significant increase (decrease) in the future sales of mineral would result in higher (lower) fair value of the contingent consideration liability, while significant increase (decrease) in the discount rate would result in lower (higher) fair value of the liability. Changes in the fair value of this contingent consideration have been recognized through profit or loss in the consolidated statement of profit or loss.

As of December 31, 2021 and 2020, it is highly probable that the Group reaches the projected future sales. The fair value of the contingent consideration determined as of December 31, 2021 reflects this assumption and changes in metal prices.

(c) A reconciliation of fair value measurement of the contingent consideration liability is provided below:

The Group has the preferential right of acquisition of the royalty in case Gold Fields decides to sell it.

(e) Related to the investment in associates, the Group has not recognized a deferred income tax asset of US$64.8 million as of December 31, 2021, originated by the difference between the financial and taxable basis of these investments (US$64.2 million as of December 31, 2020). Management believes that the timing differences will be reversed in the future without taxable effects. There is no legal or contractual obligation that would require the Company’s management to sell its investment in its associates (which event would result in a taxable capital gain based on current tax law).

31.  Commitments and contingencies

(b) Leased concessions -

The Group pays 10% on the valued production of mineral obtained from the concessions leased by Sindicato Minero Orcopampa S.A. This concession is in force until the year 2043. The payments are included as royalties, see note 24.

Contingencies

(c) Legal procedures -

Buenaventura -

The Group is a party to legal procedures that have arisen in the normal course of business. Nevertheless, in the opinion of Buenaventura’s Management, none of these procedures, individually or as a whole, could result in material contingencies for the Group’s consolidated financial statements.

The possible contingencies amount to US$4.1 million and US$5.4 million as of December 31, 2021 and 2020, respectively. See note 15(a).

The possible tax contingencies amount to US$5.9 million and US$6.3 million as of December 31, 2021 and 2020, respectively, see note 15(a).

Yanacocha -

Conga project Constitutional claim -

On October 18, 2012, Marco Antonio Arana Zegarra filed a constitutional claim against the Ministry of Energy and Mines and Yanacocha requesting the Court to order the suspension of the Conga project as well as to declare not applicable the October 27, 2010 directorial resolution approving the Conga Project Environmental Impact Assessment (“EIA”).

On October 23, 2012, a Cajamarca judge dismissed the claims based on formal grounds finding that: (i) plaintiffs had not exhausted previous administrative proceedings; (ii) the directorial resolution approving the Conga EIA is valid, and was not challenged when issued in the administrative proceedings; (iii) there was inadequate evidence to conclude that the Conga project is a threat to the constitutional right of living in an adequate environment and; (iv) the directorial resolution approving the Conga project EIA does not guarantee that the Conga project will proceed, so there was no imminent threat to be addressed by the Court. The plaintiffs appealed the dismissal of the case. The Civil Court of the Superior Court of Cajamarca confirmed the above mentioned resolution and the plaintiff presented an appeal.

On March 13, 2015, the Constitutional Court published its ruling stating that the case should be sent back to the first court with an order to formally admit the case and start the judicial process in order to review the claim and the proofs presented by the plaintiff. Yanacocha has answered the claim. Yanacocha cannot reasonably predict the outcome of this litigation. Yanacocha has not established a provision in the accompanying financial statements for a loss arising from this contingency, which it does not consider probable.

(d) Open tax procedures –

Buenaventura –

- During 2012 and 2014, the Superintendencia Nacional de Aduanas y de Administración Tributaria (SUNAT) reviewed the income tax for 2007 and 2008. As a result, SUNAT does not recognize tax declared deductions of S/1,056,310,000 (equivalent to US$264,210,000) for the year 2007 and S/1,530,985,000 (equivalent to US$382,938,000) for the year 2008. The main unrecognized deduction is the payment made for the removal of the price component of its commercial contracts of gold. In the opinion of management and its legal counsel, the objections are unfounded so Buenaventura expects to receive a favorable result in the initiated claim process.

In November 2018, the Tax Court resolved the appeal proceedings not recognizing the contracts of physical deliveries and the contractual obligation and considers that the payments correspond to an advance financial settlement of Contracts of Derivative Financial Instruments and that the Company would not have accredited the purpose of hedge and the risks covered. The Company’s management with the support of its legal advisers initiated various administrative and judicial actions to present their arguments and defend their rights.

Notes to the consolidated financial statements (continued)

On November 10, 2020, the Tax Court confirmed the reliquidation of the tax debt determined by SUNAT corresponding to 2007 and 2008. With this ruling, on November 13, 2020, SUNAT notified the Company of the start of the compulsory collection of such taxes for S/1,567,297,000 (equivalent to US$392,013,000), composed of S/192,049,000 (equivalent to US$48,036,000) of income tax and S/1,375,248,000 (equivalent to US$343,984,000) of interest and penalties.

The Company made payments under protest during the months of November and December 2020 for S/72,065,000 (equivalent to US$18,130,000), which are recorded in the caption “Trade and other accounts receivable, net”, note 7(c). Based on the opinion of the Company’s legal advisers, management expects to obtain a favorable result in the judicial process initiated.

The Company requested to SUNAT for an installment payment program that deferred payment for six months and thereafter satisfies the amount via 66 equal monthly payments, amounting to S/1,505,948,000 (equivalent to US$376,675,000), for which has been delivered, as a guarantee, letters of guarantee for the total amount plus 5% according to the tax requests for a total of S/1,580,126,000 (equivalent to US$395,229,000).

The total amount paid of S/1,584,227,000 (equivalent to US$398,548,000), which includes the updating of interest as of July 30, 2021 for S/78,279,000 (equivalent to US$19,693,000), is recorded in the caption “Trade and other accounts receivable, net”, see note 7(c).

On December 19, 2018, the Company with the support of its legal advisors filed contentious administrative lawsuits before the Judiciary regarding the controversy of taxable years 2007 and 2008.

On December 30, 2020, the Company was notified that the claim corresponding to fiscal year 2007 has been declared unfounded by the Nineteenth Administrative Litigation Court with a Subspecialty in Tax and Customs Issues. On January 11, 2021, the Company with the support of its legal advisors filed an appeal against said judgment, which will be submitted to the Superior Court.

On May 3, 2021, the Seventh Superior Chamber declared the First Instance Judgment null and void due to an evident lack of motivation and procedural consistency. On July 15, 2021, the new oral report was made before the Court of First Instance. On January 7, 2022, the new Judgment of the Court of First Instance was issued, declaring the lawsuit unfounded. According to the sponsoring lawyers, said ruling fails to comply with the mandate of the Seventh Chamber, again incurring grounds for annulment. On January 18, 2022, the appeal of the new sentence has been filed.

The lawsuit referring to fiscal year 2008 is pending resolution in the Twenty-Second Administrative Litigation Court.

In August 2019, the Company was notified of the resolution that decided to reject the precautionary request referring to fiscal year 2007. In December 2019, a new request for precautionary measure was presented that has been rejected by the Nineteenth Administrative Litigation Court with Subspecialty in Tax and Customs Issues, which has been appealed. On August 2, 2021, the Superior Chamber confirmed the First Instance ruling that rejected the precautionary measure and the definitive filing of the Precautionary Measure was ordered.

In April 2019, the Twenty-Second Administrative Litigation Court with a Subspecialty in Tax and Customs Issues required the Company to offer an injunction for 60% of the tax amount for fiscal year 2008. In compliance with said mandate, the Company delivered the letter of credit for S/511,030,000 (equivalent to US$141,013,000) with a validity of twelve months, until April 2020. In October 2020, the Company was notified of the resolution that resolved to reject the

precautionary request referring to fiscal year 2008 and the letter of collateral delivered has been without effect and will be returned to the Company.

In December 2019, a new request for a precautionary measure was submitted to the Twenty-Second Administrative Litigation Court with a Subspecialty in Tax and Customs Issues in order to suspend collection actions for 2008. Said Court has required the Company to provide collateral for 60% of the tax debt, updated as of January 31, 2020, of S/892,682,000 (equivalent to US$223,282,000).

The main unrecognized deductions by Buenaventura are: the non-deductibility of bonuses paid to contractors, a provision of doubtful accounts not accepted as an expense and income unduly deducted. In the opinion of Management and its legal counsel, Buenaventura expects to receive a favorable result in the initiated claim and appeal process.

In December 2018, the Tax Court resolved the appeal files confirming reparations S/66,623,000 (equivalent to US$16,664,000) related to the provision for collection of doubtful receivables as an expense and unfounded income unduly deducted.

In December 2019, SUNAT initiated actions of forced collection of interest and fines for the reliquidation that it has made of prepayments from January to December 2009 and January to February 2010. These are based on the 2007 and 2008 annual tax fiscal years, which were recalculated by SUNAT with the objections mentioned in the first and second paragraphs and which are questioned in the judicial process. On December 20, 2019, SUNAT executed the forced collection of S/120,262,000 (equivalent to US$30,255,000).

Notes to the consolidated financial statements (continued)

In April 2019, the Company and its sponsoring attorneys submitted the requests for precautionary measures in order to suspend the collection actions for the tax assessment for the 2009 and 2010 fiscal years.

As a result of this audit, SUNAT does not recognize the Company deductions declared for S/94,898,000 (equivalent to US$23,736,000). The main disagreements are related to the non-deductibility of bonus paid to contractors, which also affects the compensation of tax losses that can be withheld and the use of balances in favor that are not recognized by SUNAT. In the opinion of management and its legal advisors, these repairs don’t have technical support, so that a favorable result in the claim process that they have initiated is expected to be obtained.

On November 12, 2020, the Tax Court (last administrative instance) resolved the appeal, declaring founded, in part, the payment of bonuses to contractors and confirming the non-recognition of compensation for tax losses.

The main assertions made by the SUNAT include the non-deductibility of bonuses paid to contractors, the compensation of tax losses that can be withheld and the use of balances in favor that are not recognized by SUNAT. Based on the opinion of the Company’s legal advisers, management expects to obtain a favorable result in the judicial process initiated.

On March 15, 2021, the Tax Court (last administrative instance) has resolved the appeal, declaring, in part, the payment of bonuses to contractors and confirming the lack of compensation for tax losses and use of balance in favor for a total of S/139,235,000 (equivalent to US$34,826,000).

On July 23, 2021, the Tax Court (last administrative instance) has resolved the appeal declaring founded, in part, the claim for the repair of the tax credit for the bonuses paid to contractors and its impact on the carryover of the balance in favor of the exporter.

Subsidiaries –

Sociedad Minera El Brocal S.A.A. –

On May 30, 2014, SUNAT issued tax and fines assessments related to the 2011 income tax of El Brocal. They do not recognize the deduction of the loss in derivative financial instruments, the expense in mining royalties and the expenses of feeding of third parties within the terms of law. El Brocal filed an appeal that is pending resolution to date. It should be noted that on June 18, 2014, El Brocal decided to pay under protest the income tax assessment of S/8,333,000 (equivalent to US$2,096,000) so it can have access to reduced fine. This payment has been recorded as part of account receivables in the caption “Trade and other accounts receivable , net", see note 7(c).

On January 8, 2015, SUNAT notified El Brocal of a tax assessment for the 2012 income tax year related to deductions claimed by the subsidiary and rejected by SUNAT. As a result of the rejection of these deductions, SUNAT notified a tax assessment for income tax payments from January to December 2012, which amounts to S/4,030,000 (equivalent to US$1,008,000). El Brocal has filed an appeal to the Tax Court, which is pending resolution.

On June 14, 2017, SUNAT notified El Brocal of its determinations and fine resolutions as a result of the inspection procedure initiated for the 2013 income tax year where the balances in favor and the taxable tax loss are repaired. These resolutions were claimed without favorable results. On January 24, 2018, El Brocal filed the appeal before the Tax Court.

Notes to the consolidated financial statements (continued)

On August 9, 2019, El Brocal filed an administrative contentious lawsuit against the decision of the Tax Court since El Brocal had provided reliable documentation regarding the basis for the deductibility associated with the loss on derivative financial instruments and payment of mining royalties.

As of December 31, 2021, the possible contingencies regarding El Brocal amount to S/5,468,000 equivalent to US$1,274,000 (S/5,220,000 equivalent to US$1,445,000 as of December 31, 2020).

Based on the opinion of El Brocal’s legal advisers, management expects to obtain a favorable result and therefore it has not recorded a provision for these contingencies.

During 2019, SUNAT reviewed the tax return for El Brocal’s fiscal year 2015. As a result of this review, SUNAT communicated on December 31, 2019 its determination and resolutions where it questions the depreciation rate of two tailings and the deduction of the development costs of the Smelter Project for a total S/13,930,000 (equivalent to US$3,484,000) determining a debt of S /3,412,000 (equivalent to US$853,000). Management of El Brocal and its legal advisors considered that the findings rendered by the SUNAT are not supported by the technical merits of the positions taken by the SUNAT and have started the claim process.

On January 27, 2020, El Brocal made a payment of S/1,456,000 (equivalent to US$366,000), which has been recorded in the caption “Trade and other accounts receivable , net“, see note 7(c) as it expects to recover this amount.

During 2020, SUNAT reviewed the income tax return for the year 2014. As a result of this review, SUNAT notified El Brocal on December 30, 2020 of its determination Resolutions and the Fine where it questions the depreciation rate of two tailings dams, the deduction of the development costs of the Tajo Smelter Project and certain operating expenses for a total of S/16,582,000 (equivalent to US$4,148,000) determining an amount to be paid of S/10,902,000 (equivalent to US$2,727,000). El Brocal's management and its legal advisors consider that the findings have no technical merit and have initiated the claim process.

On January 7, 2021, El Brocal paid the tax assessment under protest in order to benefit from a reduction of the fine. The amount disbursed of S/7,871,000 (equivalent to US$1,980,000) has been recorded in the caption “Trade and other accounts receivable, net”, see note 7(c).

On May 21, 2021, SUNAT resolved the appeal, nullifying the initial observation referring to the deduction of the development costs of the Tajo Smelter Project and has confirmed its initial finding related to the deductions taken for the depreciation of the tailings for S/6,018,000 (equivalent US$1,505,000) and operating expenses for S/5,384,000 (equivalent to US$1,347,000). As a result of the ruling, SUNAT has returned part of the fine for S/3,003,000 (equivalent to US$755,000) so that as of December 31, 2021, an account receivable is recognized of S/4,868,000 (equivalent to US$ 1,225,000), note 7(c). Management of El Brocal and its legal advisors consider that the SUNAT’s findings are unfounded and the appeal process has begun before the Tax Court on June 11, 2021.

Minera La Zanja S.R.L. -

During the years 2016, 2017 and 2018, SUNAT audited the income tax return for the years 2013 and 2015; as a result, SUNAT does not recognize deductions for payments of profit sharing of workers, payments for police protection, balance of profit sharing and the exchange difference associated with the provision for mine closures. On November 20, 2020, the Tax Court has confirmed the position associated with the profit sharing and the exchange difference for the provision for mine

Notes to the consolidated financial statements (continued)

closure. As a result, on March 18, 2021, SUNAT has revised the imputed amount to be paid for the years 2013 and 2015 for S/3,438,000 (equivalent to US$860,000) that Minera La Zanja S.R.L. has proceeded to pay.

Possible contingencies for deductions not recognized by SUNAT that have been paid amount to S/3,060,000 (equivalent to US$770,000)and are recorded in the caption “Trade and other accounts receivable, net”, see note 7(c).

In the opinion of management and its legal advisors, the interpretation of the Tax Court is unsupported, therefore Minera La Zanja S.R.L., on March 9, 2021, has initiated a contentious-administrative lawsuit that is pending resolution in the Twenty-First Court of Administrative Litigation with Tax Subspecialty of Lima.

Empresa de Generación Huanza S.A. -

During 2015, SUNAT audited the 2014 income tax return of the Company’s subsidiary Huanza. As a result, a portion of the depreciation of its fixed assets was not recognized for S/27,532,000 (equivalent to US$6,886,000). The possible contingency amounts to S/7,993,000 (equivalent to US$1,999,000) as of December 31, 2021 (S/7,532,000 equivalent to US$1,884,000 as of December 31, 2020). In the opinion of Huanza’s management and of its legal advisors, this interpretation has no basis and therefore Huanza expects to obtain a favorable result in the appeal process that has begun.

Procesadora Industrial Río Seco S.A.-

The Customs Division of the SUNAT has determined an alleged omission in the payment of the General Sales Tax of S/1,815,000 (equivalent to US$454,000) in an import made in 2012 of certain equipment for the construction of Rio Seco’s industrial plant. SUNAT supported its position that Rio Seco should have included the amount of the consideration paid by Río Seco for the engineering services provided by its suppliers abroad in the customs value. In the opinion of management and its legal advisors, this observation is not substantiated and a favorable ruling is expected to be obtained in the complaint and appeal process.

On March 13, 2019, the Tax Court issued Resolution No. 0844-A-2019 that confirmed the observation of the Tax Administration.

On May 17, 2019, SUNAT initiated coercive collection actions for the tax amount assessed. Río Seco initiated several administrative and judicial actions to suspend the payment, without favorable results. During July to September 2019, Tax Administration executed the forced collection of the tax to be paid amounting to S/11,153,000 (equivalent to US$3,162,000). In the opinion of the legal advisors of Río Seco, a favorable result should be obtained in the judicial process that has been initiated, and therefore the amount paid has been recorded in the heading “Trade and other receivables, net”, see note 7(c).

On June 13, 2019, Río Seco has filed an administrative contentious lawsuit against the Tax Court’s Resolution seeking to overturn the Tax Administration’s objection.

Chaupiloma -

SUNAT has issued determination resolutions for fiscal years 2001, 2005, 2008, 2009, 2010, 2011 and 2013 challenging the recognition of the amortization of the investment in the mining concessions that was carried out according to the provisions of the Income Tax Law and that, according to SUNAT, said amortization should have been carried out according to the provisions of the General Mining Law applicable to the owners of mining activities. Deductions not recognized by SUNAT are S/10,500,000 (equivalent to US$2,626,000). In successive rulings, the Tax Court has confirmed that the amortization and deduction made by the Company has been carried out in accordance with the applicable law and has rendered the determination resolutions null. SUNAT has appealed to the Judiciary and has filed contentious-administrative lawsuits for the fiscal years 2008-2009, 2011 and 2013 to which Chaupiloma is responding to. In the opinion of management and Chaupiloma's legal advisors, it is expected that a favorable result will be obtained in the different judicial processes that are in process.

On June 11, 2021, the Tax Court resolved the audit file for fiscal years 2001-2005, ruling that the amortization taken for the year 2001 was not deductible because the concessions were not being exploited in said period. The Company has paid, under

protest, the tax amount for 2001 of S/1,270,000 (equivalent to US$323,000), which has been recorded in the caption “Trade and other accounts receivable, net”, see note 7(c) since in the opinion of Chaupiloma’s management and its legal advisors expect a favorable result to be obtained through the legal proceedings that have been initiated.

Mining Royalties

On June 23, 2004, Law N ° 28528 - Law of Mining Royalty was approved under which the owners of mining concessions had to be paid as financial compensation for the exploitation of metallic and non-metallic mineral resources. A mining royalty was determined applying rates that ranged between 1% and 3% on the value of the concentrate or its equivalent, according to the price quotation of the international market published by the Ministry of Energy and Mines. Based on the terms of an agreement signed in 1998 with the government of Peru, Cerro Verde determined that the payment of mining royalties was not applicable, because the new law was signed after the signing of the contract with the Peruvian Government. However, under the terms of its new guarantee contract, which became effective on January 1, 2014, Cerro Verde began to pay mining royalties and special mining tax for all its production based on Law No. 29788, which is calculated based on the operating profit with rates that fluctuate between 1% and 12%. The amount to be paid for the mining royalty will be the highest amount that results from calculating the result of applying the applicable tax rate on the quarterly operating profit (the rate is established based on the operating margin for the quarter) or 1% of revenues generated by sales made in the calendar quarter.

SUNAT has also assessed mining royalties on materials processed by Cerro Verde´s concentrator, which commenced operations in late 2006. These assessments cover the period December 2006 to December 2013. Cerro Verde contested each of these assessments because it believes that its 1998 stability agreement exempts it from royalties all minerals extracted from its mining concession, irrespective of the method used for processing such minerals. No assessments can be issued for years after 2013, as Cerro Verde began paying royalties on all of its production in January 2014 under its new 15-year stability agreement.

Since 2017, Cerro Verde has recorded payments of S/2.8 billion (approximately US$771.2 million at closing exchange rate as of December 31, 2020, including interest, deferral interest and penalties of US$496.5 million) related to the tax observations for mining royalties and special tax on mining for the period from December 2006 to December 2013. Since 2014, Cerro Verde has been paying these disputed assessments for the period from December 2006 to December 2013 through fractionation programs (granted through a schedule equivalent to 66 monthly installments), all under protest. In August 2021, Cerro Verde decided to make the payment of the entire amount of the pending subdivisions in advance and under protest. As of December 31, 2021, Cerro Verde has made payments totalling S/2.9 billion (equivalent to US$791.9 million based on the exchange rate on the payment date).

On February 2020, Cerro Verde filed arbitration proceedings with the International Centre for Settlement of Investment Disputes (CIADI) and on October 19, 2021, Cerro Verde formally filed the arbitration claim.

On March 31, 2021, Superintendence Resolution 044-2021 / SUNAT was published, establishing the new monthly default interest rate effective from April 1, 2021. The moratory interest rate in national currency ranges from 1 % to 0.9%.

Cerro Verde has also received assessments from SUNAT for additional taxes (other than the mining royalty), including penalties and interest. Cerro Verde has filed or will file objections to the assessments because it believes it has properly determined and paid its taxes. A summary of these assessments follows:

33.    Disclosure of information on segments

Management has determined its operating segments based on reports that the Group’s Chief Operating Decision Maker (CODM) uses for making decisions. The Group is organized into business units based on its products and services, activities and geographic locations. The broad categories of the Group’s business units are the following:

- Production and sale of minerals (mining units in operation).

- Exploration and development projects.

- Energy generation and transmission services.

- Insurance brokerage.

- Rental of mining concessions.

- Holding of investment in shares (mainly in the associate company Minera Yanacocha S.R.L.).

- Industrial activities.

The accounting policies used by the Group in reporting segments internally are the same as those contained in the notes of the consolidated financial statements.

The CODM monitors the operating results of the business units separately for the purpose of making decisions about resource allocation and performance assessment. Segment performance is evaluated based on operating profit or loss and is measured consistently with operating profit or loss in the Group’s consolidated financial statements. In addition, the Group’s financing and income taxes are managed at the corporate level and are not allocated to the operating segments, except for those entities,which are managed independently.

Corporate information mainly includes the following:

In the segment information of profit or loss -

- Sales to third parties of gold purchased by the Parent company from La Zanja mining unit and the corresponding cost of sale as well as other intercompany sales.

F-101

Notes to the consolidated financial statements (continued)

(a) Copper prices hedge -

The volatility of copper prices during the last years has caused management of the Company's subsidiary El Brocal to enter into forward contracts. These contracts are intended to reduce the volatility of the cash flows attributable to the fluctuations in the copper and zinc price in accordance with existing copper concentrate sales commitments, which are related to 50% of the annual production of copper and 25% of the production of two years of zinc, according to the risk strategy approved by the Board of Directors.

During 2021, the effect in profit or loss was a loss of US$51,952,000 and it is show in the “Sales of goods” caption (loss of US$6,464,000 in the year 2020 and profit of US$4,322,000 in the year 2019), see note 20(b).

The variation in the fair value of the caption generated a gain of US$9.5 million, a loss of US$15.8 million and a loss of US$2.8 million for 2021, 2020 and 2019, which are included within the consolidated statement of other comprehensive income and in ” Other comprehensive loss".

(c) Interest rate hedge -

In order to mitigate the exposure to the risk of changes in the interest rate related to its financial obligations, on April 2, 2020, the Company's management decided to enter into forward contracts in relation to the LIBOR three-month with BBVA Banco Continental, Banco de Credito del Perú, Banco Internacional del Perú and Itaú, which are designated as cash flow hedges.

There is an economic relationship between the hedged assets and the hedging instruments as the terms of the forward contracts are the same as the terms of the highly probable forward contracts. The Company has established a hedging ratio of 1: 1 for hedging relationships as the underlying risk of interest rate forward contracts are identical to the hedged risk components. In order to evaluate the effectiveness of the hedges, the Company uses the hypothetical derivative method, by which it compares the changes in the fair value of the hedging instruments against the changes in the fair value of the hedged items attributed to the hedged risks.

For the years ended December 31, 2021 and 2020, the effect on results was a loss of US$1,547,000 and US$146,000, respectively and is presented in the caption of “Financial costs and financial income” see note 29(a).

Variations in the fair value of hedging financial instruments generated a gain of US$2.0 million and an expense of US$2.6 million for 2021 and 2020, respectively, which are presented in the consolidated statement of comprehensive income within other comprehensive loss.

On January 3, 2022, the derivative hedging instruments were settled in advance generating a loss in results of US$804,000. Additionally, the net variation in the unrealized gain in derivative financial instruments maintained as of December 31, 2021 was recycled into results of the period.

35.         Financial - risk management objectives and policies

The Group’s principal financial liabilities, other than derivatives, comprise of trade accounts and other payables, and financial obligations. The main purpose of these financial instruments is to finance the Group’s operations. The Group’s principal financial assets include cash and cash equivalents and trade and other receivables that derive directly from its operations.

The Group is exposed to market risk, credit risk and liquidity risk. The Group’s management oversees the management of these risks. A committee that advises on financial risks supports it. This committee provides assurance to management that the Group’s financial risk activities are governed by appropriate policies and procedures and that financial risks are identified, measured and managed in accordance with the Group’s policies and risk objectives. All derivative activities for risk management purpose are carried out by internal specialists that have the appropriate skills, experience and supervision.

There were no changes in the objectives, policies or processes during the years ended December 31, 2021, 2020 and 2019.

The Board of Directors reviews and agrees policies for managing each of these risks, which are described below:

(a) Market risk -

Market risk is the risk that the fair value of the future cash flows from financial instruments will fluctuate because of changes in market prices. Market risks that apply to the Group comprise four types of risk: exchange rate risk, commodity risk, interest rate risk and other pricing, such as the risk of the stock price. Financial instruments affected by market risks include time deposits, financial obligations, embedded derivatives and derivative financial instruments.

The sensitivity analyses in this section relate to the positions as of December 31, 2021 and 2020 and have been prepared considering that the proportion of financial instruments in foreign currency are constant.

(a.1)       Exchange rate risk

F-112

Notes to the consolidated financial statements (continued)

The exchange rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in foreign exchange rates. The Group’s exposure to the risk of changes in foreign exchange relates primarily to the Group´s operating activities in soles. The Group mitigates the effect of exposure to exchange-rate risk by carrying out almost all of its transactions in its functional currency.

Excluding loans in soles, management maintains smaller amounts in soles in order to cover its needs in this currency (primarily payment of taxes).

A table showing the effect on results of a reasonable change in foreign-currency exchange rates is presented below, with all other variables kept constant:

	Exchange-rate		Effect on profit (loss)
	increase/decrease		before income tax
			US$(000)
2021
Exchange rate	10	%	56,122
Exchange rate	(10)	%	(56,122)
2020
Exchange rate	10	%	7,591
Exchange rate	(10)	%	(7,083)
2019
Exchange rate	10	%	4,053
Exchange rate	(10)	%	(3,545)

(a.2)       Commodity price risk

The Group is affected by the price volatility of the commodities. The price of mineral sold by the Group has fluctuated historically and affected by numerous factors beyond its control.

The Group manages its commodity price risk primarily using sales commitments in customer contracts and hedge contracts for the metals sold by the subsidiary El Brocal.

The Company’s subsidiary El Brocal entered into derivative contracts that qualified as cash flow hedges, with the intention of mitigating the risk resulting from the decrease in the prices of its minerals. These derivative contracts are recorded as assets or liabilities in the consolidated statements of financial position, see note 14, and are stated at fair value. To the extent that these hedges were effective in offsetting future cash flows from the sale of the related production, changes in fair value are deferred in an equity account under “Other comprehensive income (loss)". The amounts included temporarily in other comprehensive income (loss) are reclassified to the “sales of goods” when the related minerals are sold. See note 34(a) and note 20(b).

(a.3)       Interest rate risk -

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group’s exposure to the risk of changes in market interest rates relates to the Groups’ long-term financial obligations with floating interest rates.

F-113

Notes to the consolidated financial statements (continued)

Interest rate	10	%	(81)
Interest rate	(10)	%	81
2019
Interest rate	10	%	(306)
Interest rate	(10)	%	306

(b) Credit risk -

Credit risk is the risk that counterparty will not meet its obligations under a financial instrument or customer contract, leading to a financial loss. The Group is exposed to credit risk from its operating activities (primarily trade receivable) and from its financing activities, including deposits with banks and other financial instruments.

The Group invests the excess cash in leading financial institutions, sets conservative credit policies and constantly evaluates the market conditions in which it operates.

Trade accounts receivable are denominated in U.S. dollars. The Group’s sales are made to domestic and foreign customers. See concentration of spot sales in note 20(b). An impairment analysis is performed on an individual basis.

Credit risk is limited to the carrying amount of the financial assets to the date of consolidated statements of financial position, which is composed, by cash and cash equivalents, trade and other receivables and derivative financial instruments.

(c) Liquidity risk -

Prudent management of liquidity risk implies maintaining sufficient cash and cash equivalents and the possibility of committing or having financing committed through an adequate number of credit sources. The Group believes that maintains suitable levels of cash and cash equivalents and has sufficient credit capacity to get access to lines of credit from leading financial entities.

The Group continually monitors its liquidity risk based on cash flow projections.

36.         Fair value measurement

Fair value disclosure of assets and liabilities according to its hierarchy -

The following table provides the fair value measurement hierarchy of the Group’s assets and liabilities:

		Fair value measurement using:
		Quoted prices
		in active	Observable	Unobservable
		markets	inputs	inputs
	Total	(Level 1)	(Level 2)	(Level 3)
	US$(000)	US$(000)	US$(000)	US$(000)
As of December 31, 2021-
Assets and liabilities measured at fair value:
Fair value of account receivable (subject to provisional pricing)	133,977	—	133,977	—
Bank loans	50,000	—	50,000	—
Financial obligations	1,059,236	—	1,059,236	—
Contingent consideration liability	17,718	—	—	17,718
Hedge instruments	6,976	—	6,976	—
As of December 31, 2020 -
Assets and liabilities measured at fair value:
Fair value of account receivable (subject to provisional pricing)	126,553	—	126,553	—
Bank loans	65,793	—	65,793	—
Financial obligations	475,624	—	475,624	—
Contingent consideration liability	22,100	—	—	22,100
Hedge instruments	18,439	—	18,439	—

Financial instruments whose fair value is similar to their book value –

For financial assets and liabilities such as cash and cash equivalents, trade and other receivables, trade and other payables that are liquid or have short-term maturities (less than three months), it is estimated that their book value is similar to their fair value. The Group’s derivative financial instruments are recorded at their fair value.

The fair value of accounts receivable is determined using valuation techniques with information directly observable in the market (future metal quotations).

Financial instruments at fixed and variable rates -

The fair value of financial assets and liabilities at fixed and variable rates at amortized cost is determined by comparing the market interest rates at the time of their initial recognition to the current market rates with regard to similar financial instruments. The estimated fair value of deposits that accrue interest is determined by means of cash flows discounted using the prevailing market interest rates in the currency with similar maturities and credit risks.

Based on the foregoing, there are no important existing difference between the book value and the fair value of the assets and financial liabilities as of December 31, 2021 and 2020. There were no transfers between Level 1and Level 2 during 2021 and 2020.

As of December 31, 2021, there are no investment properties owned by the Group. As of December 31, 2020, the fair value of the investment property amounted to US$842,000. There was not an independent valuation for investment property.

Fair value measurements using significant unobservable inputs (level 3) –

Notes to the consolidated financial statements (continued)

The following table summarizes the quantitative information about the significant unobservable inputs used in level 3 fair value measurements:

	Fair value as of
	December 31,	Unobservable			Relationship of unobservable
Description	2021	inputs	Range of inputs		inputs to fair value
Contingent consideration liability	17,718	Rate before tax	8.73	%	A change in the discount rate by 10% (rate of 0.873%) higher/lower, the fair value would increase/decrease in US$1.4 million.
		Expected revenues annual average (US$000)	193,972		If expected sales change by 10% higher/lower, the fair value would increase/decrease in US$1.8 million.

37.         Events after the reporting period

Report of Independent Registered Public Accounting Firm

To the Partners of Minera Yanacocha S.R.L.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statements of financial position of Minera Yanacocha S.R.L. and subsidiary (the Company) as of December 31, 2021 and 2020, and related consolidated statements of comprehensive income, changes in equity (deficit) and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company at December 31, 2021 and 2020, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board which differ in certain respects from the accounting principles generally accepted in the United States of America (see notes 27 and 28 to the consolidated financial statements).

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Other matters

As explained in note 1 of the Notes to the consolidated financial statements, the Partners’ equity is lower than one third of its Partners’ contribution as of December 31, 2021 and shows a deficit of US$643,938,000. In accordance with Articles 407 and 423 of Peruvian Corporations Law, the Company is within a cause of dissolution and irregular situation. The Company has the financial support from its controlling partner and expects to rectify this irregularity in the next twelve months. Management is assessing legal ways to rectify the irregular situation including obtaining new capital contributions from its partners. Our opinion is not modified in respect to this matter.

Minera Yanacocha S.R.L. hereinafter “the Company” or “Yanacocha”, was incorporated in Peru on January 14, 1992 and commenced operations in 1993. The Company is currently engaged in the production, exploration and development of gold under the mining concessions it owns or that are owned by S.M.R.L. Chaupiloma Dos de Cajamarca (Chaupiloma). Future projects could include the production, exploration and development of copper as well.

At the year-end, the Company was 51.35% owned by Newmont Second Capital Corporation, a 100% indirectly owned subsidiary of Newmont Corporation ("Newmont", the ultimate Parent company), 43.65% owned by Compañía Minera Condesa S.A., which is 100% owned by Compañía de Minas Buenaventura S.A.A. (Buenaventura) and 5% owned by Summit Global Management II VB, a wholly-owned subsidiary of Sumitomo Corporation.

The controlling Partners of the Company (or their affiliates) also own the controlling interest in Chaupiloma. In accordance with a mining lease agreement, amended and effective on January 1, 1994, the Company pays Chaupiloma a 3% royalty based on quarterly production sold at current market prices, after deducting refinery and transportation costs. The royalty agreement expires in 2032.

In February 2022, Newmont completed the acquisition of Buenaventura's 43.65% noncontrolling interest in Yanacocha for $300 million cash consideration, certain royalties on any production from other future potential projects, and contingent payments of up to $100 million tied to the outstanding Yanacocha tax dispute (see note 24), higher metal prices and achieving commercial production at the Yanacocha Sulfides project. In addition, certain changes were made to the Chaupiloma royalty agreement. Upon close of the Yanacocha Transaction, Newmont's ownership interest in Yanacocha increased to 95%.

The Company’s legal domicile is at La Paz avenue No. 1049 office 401, Miraflores, Lima Peru.

A fine is payable for the years in which minimum production or investment requirements are not met. No fines were in the last years in relations to the Company's concessions. The Company holds mining concessions which exploration and processing rights do not expires as long as the Company comply with the legal requirements. To date the Company has complied with all the applicable legal requirements related to its concession rights.

The Yanacocha Complex mined material from the Yanacocha Layback and Yanacocha Pinos, which will finish mining operations in 2022. The Yanacocha Complex began operations in 1997 and has had limited mining operations in recent years.

The Carachugo Complex and Maqui Maqui includes mined material from multiple mines that are no longer in operation and continued residual gold leaching. In addition, the Carachugo Complex includes processed material from the Quecher Main project, which is an open pit within the existing footprint of Yanacocha and began operating in October 2019. This project will add oxide production at Yanacocha is the primary source of ore for the Yanacocha operation (to 2027) ahead of an investment in the Sulfides project. During 2021 and 2020, the ounce production of the project was 63,000 oz and 55,000 oz of gold respectively.

Yanacocha’s gold processing plants are located adjacent to the solution storage ponds and are used to process gold-bearing solutions from Yanacocha’s leach pads through a network of solution-pumping facilities and the Yanacocha Gold Mill processes high-grade gold ore to produce a gold-bearing solution for treatment at the La Quinua processing plant, followed by Merrill - Crowe zinc precipitation and smelting where a final dore product is poured. The dore is then shipped offsite for refining and is sold on the worldwide gold markets. The Yanacocha Gold Mill ceased current operations in February 2021.

Gold mining requires the use of specialized facilities and technology. The Company relies heavily on such facilities and technology to maintain production levels. Also, the cash flows and profitability of the Company’s operations are significantly affected by the market price of gold. Gold prices can fluctuate widely and are affected by numerous factors beyond the Company’s control. During 2021, 2020 and 2019 the Company produced 264,000, 340,000 and 527,000 of gold ounces, respectively.

Brownfield exploration and development for new reserves is ongoing, within the existing footprint of Yanacocha. In addition, the Company continues to evaluate the potential for mining oxide and sulfide gold and copper mineralization.

Conga project

The Conga Project consists of two gold-copper porphyry deposits located northeast of the Yanacocha operating area in the provinces of Celendin, Cajamarca and Hualgayoc. There is no exploration and (or) development of new reserves, the reserve balances reported for Conga in 2014 were reclassified to mineralized material in 2015.

The Conga project has historically been the target of local political and community protests, some of which, many years back, blocked the road between the Yanacocha mine and Conga project complexes and the City of Cajamarca in Peru and resulted in vandalism and equipment damage. While recently roadblocks and protests have diminished and focused on local political activism and labor disputes, the Company cannot predict whether similar or more significant incidents will occur in the future. The recurrence of significant political or community opposition or protests could continue to adversely affect the Conga Project’s development, other new projects in the area and the continued operation of Yanacocha.

Construction activities on the Conga project were suspended in 2011, at the request of Peru’s central government following protests in Cajamarca by anti-mining activists led by the regional president. At the request of the Peruvian central government, the environmental impact assessment prepared in connection with the project was reviewed by independent experts in an effort to resolve allegations around the environmental viability of Conga. This review concluded that the environmental impact assessment complied with international standards and provided recommendations to improve water management. Based on the Company's internal project portfolio evaluation process, the Company has reprioritized other projects ahead of the Conga project, and therefore does not anticipate developing Conga in the next ten years. Due to the uncertainty surrounding the project’s development timeline, the Company has allocated its exploration and development capital to other projects in its portfolio. As a result, the Conga project is currently in care and maintenance and Management will continue to evaluate long-term options to progress development of the Conga project. Should the Company be unable to develop the Conga project or conclude that future development is not in the best interest of the business, a future impairment charge may result.

During 2021, the Company entered into a binding agreement to sell certain equipment and assets for the Conga project, for total cash proceeds of US$68 million , net of associated cost for sale for US$46 million. The book value of these assets

F-127

Notes to the consolidated financial statements (continued)

before classification as held for sale was US$174 million, accordingly, the Company recognized an expense of US$152 million. Pursuant to the terms of the agreement, the sale is expected to close upon delivery of the assets and receipt of the final payment at which time title and control of the assets will transfer, currently expected to occur within approximately one year. As of December 31, 2021, the Company has collected US$17 million as part of the initial payment of the transaction.

The Central Government of Peru supported responsible mining as a vehicle for the growth and future development of Peru. However, the Company is unable to predict whether the Central government will continue to take similar positions in the future.

Previous regional governments of Cajamarca and other political parties actively opposed certain mining projects in the past, including by protests, community demands and road blockages, which may occur again in the future. The Company is unable to predict the positions that will be taken by the Central or regional government and neighboring communities in the future and whether such positions or changes in law will affect current operations and new projects at Yanacocha or Conga. Risks related to mining and foreign investment under the new administration include, without limitation, risks to mining concessions, land tenure and permitting, increased taxes and royalties, nationalization of mining assets and increased labor regulations, environmental and other regulatory requirements. Any change in government positions or laws on these issues could adversely affect the assets and operations of Yanacocha or Conga, which could have a material adverse effect on our results of operations and financial position. Additionally, the inability to develop Conga or operate at Yanacocha could have an adverse impact on the Company's growth and production in the region.

Should the Company be unable to develop the Conga project, the Company may have to consider other alternatives for the project, which may result in a future impairment charge. The total assets at Conga as of December 31, 2021 and 2020 were US$262 million and US$449.8 million, respectively.

Sulfides project

This project represents a stream of sulfide resources development that will be achieved by processing high-grade metal dominant sulfide ores from Yanacocha Verde Phase 1 and Chaquicocha underground deposits within Yanacocha’s operational footprint, through an integrated process flow sheet that includes the addition of new flotation, pressure oxidation, neutralization, solvent extraction and electrowinning facilities. The Sulfides project is in the final feasibility stage, and the Company expects to begin with the development stage of the project in the second half of the year 2022. During 2021, the Board of Newmont approved an investment of US$500 million to continue to the development phase of the Sulfide project.

Negative equity

Currently, the Company has negative equity due to recognition of the update of the reclamation liability in 2021, see note 13. Its Partners´ equity is lower than one third of its Partners´ contribution as of December 31, 2021 and shows a deficit of US$ 643,938,000. In accordance with Articles 407 and 423 of Peruvian Corporations Law, the Company is within a cause of dissolution and irregular situation, until it regularizes its status. The Company is economically supported by its Partners and Management is assessing legal ways to rectify this situation in the following twelve months, including obtaining new capital contributions from its controlling Partner.

(c) Approval of consolidated financial statements -

The consolidated financial statements as of December 31, 2021 were approved by the Company’s Management on May 13, 2022, and subsequent events have been considered through that date. Those shareholders have the authority to approve and or otherwise modify the consolidated financial statements. The consolidated financial statements as of December 31, 2020 were approved by the Partners’ Meeting held on March 29, 2021.

(d) Covid 19 outbreak -

Covid-19, an infectious disease caused by a new coronavirus, was declared a global pandemic by the World Health Organization on March 11, 2020. Measures to decrease the spread of Covid-19 have had a significant impact on the Global economy.

F-128

Notes to the consolidated financial statements (continued)

On March 15, 2020, the Peruvian Government declared a state of emergency at the national level, closing all businesses considered non-essential (the exceptions were the production and marketing of food, pharmaceutical products, financial services and health). Despite the fact that the state of emergency remained in force until October 31, 2020, the Peruvian Government allowed the early restart of the economic activities of certain industries. After the interruption of operations for 61 days, the Company resumed near normal operations as of the month of September 2020.

The Company has taken various measures to preserve the health of its employees and to prevent contagion in the administrative and operational areas of each subsidiary, such as remote work, reorganization of its facilities, rigorous cleaning of work environments, distribution of equipment personal protection, preventive tests before access to the mining unit and body temperature measurement, and requirement for full vaccination.

2.     Basis for preparation, consolidation and accounting policies

2.1.  Basis of preparation -

The consolidated financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standard Board (IASB).

The consolidated financial statements have been prepared under the historical cost basis, except for accounts receivables and financial assets which are measured at their fair value and assets held for sale that are measured at the lower of its carrying amount and its fair value less cost to sale. The consolidated financial statements are prepared on the basis that it will continue as going concern.

The consolidated financial statements are presented in U.S. dollars and all values are rounded to the nearest thousands, except when otherwise indicated.

The preparation of consolidated financial statements requires that Management use judgments, estimates and assumptions, as detailed in note 3.

2.2.  Basis of consolidation -

The consolidated financial statements comprise the financial statements of the Company and its subsidiary (San Jose Reservoir Trust, a separate Peruvian legal entity created to ensure the continuity of the Company’s operations in the San Jose Reservoir after the end of operations at Yanacocha).

Control is achieved when the Company is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Company controls an investee if, and only if, the Company has:

-      Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee).

-      Exposure, or rights, to variable returns from its involvement with the investee.

-      The ability to use its power over the investee to affect its returns.

Generally, there is a presumption that a majority of voting rights result in control. To support this presumption and when the Company has less than a majority of the voting or similar rights of an investee, the Company considers all relevant facts and circumstances in assessing whether it has power over an investee, including:

-      The contractual arrangement with the other vote holders of the investee.

-      Rights arising from other contractual arrangements.

-      The Company’s voting rights and potential voting rights or a combination of rights.

The Company re-assesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Assets, liabilities, income and expenses of a

F-129

Notes to the consolidated financial statements (continued)

subsidiary acquired or disposed of during the year are included in the consolidated financial statements from the date the Company gains control until the date the Company ceases to control the subsidiary.

When necessary, adjustments are made to the consolidated financial statements of the subsidiary to bring its accounting policies into line with the Company’s accounting policies.

All intra-group assets and liabilities, equity, income, expenses and cash flows are eliminated in full on consolidation.

A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction.

2.3.  Changes in accounting policies and disclosures -

Below is a summary of the changes in accounting policies and disclosures applicable for the year 2021:

Interest Rate Benchmark Reform - Phase 2: Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 -) –

The amendments provide temporary reliefs which address the financial reporting effects when an interbank offered rate (IBOR) is replaced with an alternative nearly risk-free interest rate (RFR). The amendments include the following practical expedients:

- A practical expedient to require contractual changes, or changes to cash flows that are directly required by the reform, to be treated as changes to a floating interest rate, equivalent to a movement in a market rate of interest.

- Permit changes required by IBOR reform to be made to hedge designations and hedge documentation without the hedging relationship being discontinued.

- Provide temporary relief to entities from having to meet the separately identifiable requirement when an RFR instrument is designated as a hedge of a risk component.

On March 5, 2021, the UK authorities confirmed that the LIBOR would cease to be published with effect as of December 31, 2021 at all terms and in all currencies except for US dollars, publication of which would continue until June 30, 2023 to facilitate the transition of current contracts.

These amendments had no impact on the consolidated financial statements of the Company. The Company intends to use the practical expedients in future periods if they become applicable.

Covid-19-Related Rent Concessions

beyond June 30, 2021 Amendments to IFRS 16 -

On May 28, 2020, the IASB issued Covid-19-Related Rent Concessions - amendment to IFRS 16 Leases. The amendments provide relief to lessees from applying IFRS 16 guidance on lease modification accounting for rent concessions arising as a direct consequence of the Covid-19 pandemic. As a practical expedient, a lessee may elect not to assess whether a Covid-19 related rent concession from a lessor is a lease modification. A lessee that makes this election accounts for any change in lease payments resulting from the Covid-19 related rent concession the same way it would account for the change under IFRS 16, if the change were not a lease modification.

The amendment was intended to apply until June 30, 2021, but as the impact of the Covid-19 pandemic is continuing, on March 31, 2021, the IASB extended the period of application of the practical expedient to June 30, 2022.The amendment applies to annual reporting periods beginning on or after April 1, 2021. However, the Company has not received Covid-19-related rent concessions, but plans to apply the practical expedient if it becomes applicable within allowed period of application.

F-130

Notes to the consolidated financial statements (continued)

Several other amendments and interpretations were applied for the first time in 2021 but they did not have an impact on the Company's consolidated financial statements and therefore have not been disclosed. The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

2.4.  Summary of significant accounting policies and practices -

(a)   Foreign currencies -

The consolidated financial statements are presented in U.S. dollars, which is also the Company’s functional currency.

Transactions and balance in foreign currency

Transactions in foreign currency (a currency other than functional currency) are initially recorded by the Company at the exchange rates prevailing at the time of the transactions published by the Superintendence of Banking and Insurance and Pension Fund Administrators (AFP for its acronym in Spanish).

Monetary assets and liabilities denominated in other currencies are translated into the U.S. dollar at exchange rates prevailing at the statements of financial position dates. Gains or losses from exchange differences arising from the settlement or translation of monetary assets and liabilities are recognized in the consolidated statements of comprehensive income. Non-monetary assets and liabilities recognized in terms of historical cost are translated using the exchange rates prevailing at the dates of the initial transactions.

Transactions in Soles (S/)

Transactions in Soles are completed using exchange rates published by the AFP. As of December 31, 2021, the exchange rates for U.S. dollars published by this Institution were US$0.2515 for buying and US$0.2501 for selling (US$0.2764 for buying and US$0.3020 for selling as of December 31, 2020), and have been applied by the Company for the assets and liabilities accounts, respectively.

As of December 31, 2021 and 2020, the Company presents the following assets and liabilities originally denominated in Soles by its equivalent in U.S. dollars:

	2021	2020
	US$(000)	US$(000)
Assets
Cash and cash equivalents	4,658	6,242
Trade and other receivables	7,283	7,584
Value added tax credit	39,989	25,214
Total assets	51,930	39,040
Liabilities
Trade and other payables	35,505	48,200
Income tax payable	11,792	37,779
Provisions, other accruals and liabilities	16,303	25,774
Total liabilities	63,600	111,753
Net liability position	(11,670)	(72,713)

For the year ended December 31, 2021, the Company recognized a net loss from currency exchange difference for US$7,311 (net gain for US$1,180 and US$2,902 for 2020 and 2019; respectively) in the caption “Net gain (loss) from currency exchange difference” of the consolidated statements of comprehensive income.

(b)   Financial instruments - Initial recognition and subsequent measurement -

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

F-131

Notes to the consolidated financial statements (continued)

(i)    Financial assets -

Initial recognition and measurement

Financial assets are classified, at initial recognition, and subsequently measured at amortized cost, fair value through other comprehensive income (OCI), and fair value through profit or loss.

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Company’s business model for managing them. With the exception of trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient, the Company initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient are measured at the transaction price as disclosed in section (n) “Revenue from contracts with customers”.

In order for a financial asset to be classified and measured at amortized cost or fair value through OCI, it needs to give rise to cash flows that are solely payments of principal and interest (SPPI) on the principal amount outstanding. This assessment is referred to as the SPPI test and is performed at an instrument level.

The Company’s business model for managing financial assets refers to how it manages its financial assets in order to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both.

Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way trades) are recognized on the trade date.

Financial assets of the Company comprise cash and cash equivalents, trade and other receivables, net and financial assets at fair value through OCI with recycling of cumulative gains and losses and financial assets at fair value through profit or loss.

Subsequent measurement -

For purposes of subsequent measurement, financial assets are classified in four categories:

-      Financial assets at amortized cost (debt instruments).

-      Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments).

-      Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments).

-      Financial assets at fair value through profit or loss.

Financial assets at amortized cost (debt instruments) -

Financial assets at amortized cost are subsequently measured using the effective interest (EIR) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired.

The Company’s financial assets at amortized cost includes other receivables, net. See note 6 for more information on accounts receivables.

Financial assets at fair value through OCI with recycling of cumulative gains and losses (debt instruments) -

For debt instruments at fair value through OCI, interest income, foreign exchange revaluation and impairment losses or reversals are recognized in the consolidated statements of comprehensive income and computed in the same manner as for financial assets measured at amortized cost. The remaining fair value changes are recognized in OCI. Upon derecognition, the cumulative fair value change recognized in OCI is recycled to profit or loss.

The Company’s investments in the San Jose Reservoir Trust are classified as financial assets at fair value through OCI as of December 31, 2021 and 2020

F-132

Notes to the consolidated financial statements (continued)

Financial assets designated at fair value through OCI with no recycling of cumulative gains and losses upon derecognition (equity instruments) -

Debt instruments at fair value through OCI includes investments in quoted debt instruments included under other non-current financial assets.

Gains and losses on these financial assets are never recycled to profit or loss. Dividends are recognized as other income in the statements of comprehensive income when the right of payment has been established, except when the Company benefits from such proceeds as a recovery of part of the cost of the financial asset, in which case, such gains are recorded in OCI. Equity instruments designated at fair value through OCI are not subject to impairment assessment.

The Company does not have financial assets classified in this category.

Financial assets at fair value through profit or loss -

Financial assets at fair value through profit or loss are carried in the consolidated statement of financial position at fair value with net changes in fair value recognized in the consolidated statements of comprehensive income.

This category includes derivative instruments and listed equity investments which the Company had not irrevocably elected to classify at fair value through OCI. Dividends on listed equity investments are recognized as other income in the consolidated statements of comprehensive income when the right of payment has been established.

A derivative embedded in a hybrid contract, with a financial liability or non-financial host, is separated from the host and accounted for as a derivative if: the economic characteristics and risks are not closely related to the host; a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and the hybrid contract is not measured at fair value through profit or loss. Embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through profit or loss category.

This category also applies to financial assets that are intended to be held for an indefinite period of time and may be sold in response to needs for liquidity, or in response to changes in the market conditions (Note 9).

Derecognition -

A financial asset (or, where applicable a part of a financial asset or part of a group of similar financial assets) is primarily derecognized when:

-     The rights to receive cash flows from the asset have expired; or

-     The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a pass-through arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset or, (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent, it has retained the risk and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company’s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Impairment of financial assets -

The Company recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at an approximation of the original

F-133

Notes to the consolidated financial statements (continued)

effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms.

ECLs are recognized in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses that result from default events that are possible within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL).

For trade receivables and contract assets, the Company applies a simplified approach in calculating ECLs. Therefore, the Company does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. The Company has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

The Company considers a financial asset in default when contractual payments are 90 days past due. However, in certain cases, the Company may also consider a financial asset to be in default when internal or external information indicates that the Company is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Company. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.

(ii)  Financial liabilities -

Initial recognition and measurement -

Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, financial liabilities at amortized cost (loans and borrowings, payables, or as derivatives designated as hedging instruments in an effective hedge), as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and borrowings and payables, net of directly attributable transaction costs.

The Company’s financial liabilities include trade and other payables.

Subsequent measurement -

The measurement of financial liabilities depends on their classification, as described below:

Financial liabilities at fair value through profit or loss -

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered into by the Company that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the consolidated statements of comprehensive income.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IFRS 9 are satisfied. The Company has not designated any financial liability as at fair value through profit or loss.

F-134

Notes to the consolidated financial statements (continued)

Financial liabilities at amortized cost (Loans and borrowings, trade payables) -

After initial recognition, interest-bearing loans and borrowing are subsequently measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the consolidated statements of profit and cost when the liabilities are derecognized as well as through the amortization process.

Amortized cost is calculated taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. Amortization under the effective interest rate method is included as financial costs in the consolidated statements of profit or loss. This category generally applies to interest-bearing loans and borrowings.

Trade and other payables are subsequently measured at amortized cost.

Derecognition -

A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the consolidated statements of comprehensive income.

(iii) Offsetting of financial instruments -

Financial assets and financial liabilities are offset and the net amount is reported in the consolidated statements of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

(c)   Current versus non-current classification -

The Company presents assets and liabilities in the consolidated statements of financial position based on current or non-current classification.

An asset is classified as current when it is:

-      Expected to be realized or intended to be sold or consumed in the normal operating cycle;

-      Held primarily for the purpose of trading;

-      Expected to be realized within twelve months after the reporting period, or

-      Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve months after the reporting period.

All other assets are classified as non-current.

A liability is current when it is:

-      Expected to be settled in the normal operating cycle;

-      Held primarily for the purpose of trading;

-      Due to be settled within twelve months after the reporting period, or

-      There is no unconditional right to defer the settlement of the liability for at least twelve months after the reporting period.

The Company classifies all other liabilities as non-current.

Deferred tax assets and liabilities are classified as non-current assets and liabilities.

F-135

Notes to the consolidated financial statements (continued)

(d)   Cash and cash equivalents -

Cash and cash equivalents include cash in hand, deposits held at call with banks and other short-term highly liquid investments with original maturities of three months or less.

Restricted cash includes guarantee deposits in escrow accounts related to Sumitomo's shares acquisition (see note 15) and is excluded from cash and cash equivalents being included in other current assets or long-term assets depending on restrictions.

(e)   Stockpiles, ore on leach pads and inventories -

Costs that are incurred in or benefit the productive process are accumulated as stockpiles, ore on leach pads and inventories. Stockpiles, ore on leach pads and inventories are carried at the lower of weighted average cost or net realizable value. Net realizable value represents the estimated future sales price of the product based on current and long-term metals prices, less the estimated costs to complete production and bring the product to sale. Write-downs of stockpiles, ore on leach pads and inventories to net realizable value are reported as a component of costs applicable to sales. The current portion of stockpiles, ore on leach pads and inventories is determined based on the expected amounts to be processed within the next twelve months. Stockpiles, ore on leach pads and inventories not expected to be processed within the next twelve months are classified as non-current. The major classifications are as follows:

(i)    Stockpiles -

Stockpiles represent ore that has been extracted from the mine and is available for further processing. Stockpiles are measured by estimating the number of tons added and removed from the stockpile, the number of contained ounces (based on assay data) and the estimated metallurgical recovery rates (based on the expected processing method). Stockpile ore tonnages are verified by periodic surveys. Costs are allocated to stockpiles based on relative values of material stockpiled and processed using current mining costs incurred up to the point of stockpiling the ore, including applicable overhead and depreciation and amortization relating to mining operations, and removed at each stockpile’s weighted average cost per recoverable unit as material is processed.

(ii)   Ore on leach pads -

The recovery of gold from certain gold oxide ores is achieved through the heap leaching process. Under this method, oxide ore is placed on leach pads where it is treated with a chemical solution, which dissolves the gold contained in the ore. The resulting gold-bearing solution is later processed in a plant where the gold is recovered. Costs are accumulated to ore on leach pads based on current mining costs, including applicable overhead and depreciation and amortization relating to mining operations, as well as leaching costs incurred in the leaching process. Costs are removed from ore on leach pads as ounces are recovered based on the weighted average cost per estimated recoverable ounce of gold on the leach pad.

The estimates of recoverable gold on the leach pads are calculated from the quantities of ore placed on the pads (measured tons added to the leach pads), the grade of ore placed on the leach pads (based on assay data) and a recovery percentage (based on ore type). In general, the leach pads recover between 50% and 95% of the ultimate recoverable ounces in the first year of leaching, declining each year thereafter until the leaching process is complete.

Although the quantities of recoverable gold placed on the leach pads are reconciled by comparing the grades of ore placed on the pads to the quantities of gold actually recovered (metallurgical balancing), the nature of the leaching process inherently limits the ability to precisely monitor inventory levels. As a result, the metallurgical balancing process is constantly monitored, and estimates are refined based on actual results over time. The Company’s operating results typically are not materially impacted by variations between the estimated and actual recoverable quantities of gold on its leach pads in the ordinary course of business. Variations between actual and estimated quantities resulting from changes in assumptions and estimates that do not result in write-downs to net realizable value are accounted on a prospective basis.

(iii) In-process inventory -

In-process inventories represent materials that are currently in the process of being converted to a saleable product. Conversion processes vary depending on the nature of the ore and the specific processing facility, and include mill in-

F-136

Notes to the consolidated financial statements (continued)

circuit and leach in-circuit. In-process material is measured based on assays of the material fed into the process and the projected recoveries of the respective plants. In-process inventories are valued at the weighted average cost of the material fed into the process attributable to the source material coming from the mines, stockpiles and (or) leach pads plus the in- process conversion costs, including applicable amortization relating to the process facilities incurred to that point in the process.

(iv) Precious metals inventory -

Precious metals include gold dore and (or) gold bullion. Precious metals that result from the Company’s mining, processing activities are valued at the weighted average cost of the respective in-process inventories incurred prior to the refining process, plus applicable refining costs.

(v)   Materials and supplies -

Materials and supplies are valued at the lower of weighted average cost or replacement value. Cost includes applicable taxes and freight.

(f) Current assets held for sale and discontinued operations

The Company classifies current assets and disposal groups as held for sale if their carrying amounts will be recovered principally through a sale transaction rather than through continuing use. Current assets and disposal groups classified as held for sale are measured at the lower of their carrying amount and fair value less costs to sell. Costs to sell are the incremental costs directly attributable to the disposal of an asset (disposal group), excluding finance costs and income tax expense. The criteria for held for sale classification is regarded as met only when the sale is highly probable, and the asset or disposal group is available for immediate sale in its present condition. Actions required to complete the sale should indicate that it is unlikely that significant changes to the sale will be made or that the decision to sell will be withdrawn. Management must be committed to the plan to sell the asset and the sale expected to be completed within one year from the date of the classification. Property, plant and equipment and intangible assets are not depreciated or amortized once classified as held for sale. Assets and liabilities classified as held for sale are presented separately as current items in the consolidated statement of financial position.

(g)Property, plant and equipment -

Property, plant and equipment is stated at cost, net of accumulated depreciation and accumulated impairment losses, if any.

The cost of an element of property, plant and equipment comprises the following: the acquisition price or manufacturing cost, including non-reimbursable customs and taxes and any cost necessary to place the asset in operating condition, as anticipated by Management; the estimate of the rehabilitation obligation and, in the case of qualified assets, the financing costs.

The purchase price or construction cost corresponds to the total amount paid and fair value of any other consideration provided to acquire the asset. Subsequent costs attributable to property, plant and equipment are capitalized only when it is probable that future economic benefits associated with the item will flow to the Company and the cost of the item can be measured reliably, otherwise the cost is charged to production or expense.

Maintenance and repair expenses are charged to the production cost or expense, as necessary, in the period when incurred.

Disbursements incurred to replace a component of an item or element of property, plant and equipment are capitalized separately, writing-off the carrying amount of the component being replaced. In the event the component replaced has not been considered as a separate component of the asset item, the replacement value of the new component is used to estimate the carrying amount of the assets being replaced.

Assets in the construction stage are capitalized on a separate caption of property plant and equipment. At their completion, the cost is transferred to the appropriate category. The work in progress is not depreciated.

Notes to the consolidated financial statements (continued)

Depreciation

Land is not depreciated. Other than land, depreciation of property, plant and equipment is calculated using the straight-line method to allocate their cost less their residual value over their estimated useful lives and in the case of assets assigned to the production process of Yanacocha, under the lower of (i) that determined under the units of production method or (ii) the useful life of the mine. The useful lives as follows:

Land improvements	Between 2 and 4  years
Buildings and constructions	Between 5 and 10 years
Machinery and equipment	Between 3 and 10 years
Vehicles	Between 3 and 4 years
Furniture and fixtures	Between 3 and 4 years
Other equipment	Between 3 and 4 years
Computer equipment	Between 3 and 4 years
Mine development, Mining rights, Leach pads and assets retirement and mine closure	Useful life of the mine and (or) process facilities

The assets’ useful lives and residual values are reviewed, and adjusted if appropriate, at each date of the consolidated statement of financial position. Any changes in these estimates are prospectively adjusted.

Disposal of assets

Property, plant and equipment items are written-off at the date they are sold or when no economic benefits are expected from their further use or sale. Gains and losses on disposals of assets are determined by comparing the proceeds with their carrying amounts. These gains or losses are included in the consolidated statements of comprehensive income.

(h)   Mining rights -

Mining rights include acquired interests in production, development and exploration stage properties. The mineral interests are capitalized at their fair value at the acquisition date.

The value of such assets is primarily driven by the nature and amount of mineralized material believed to be contained in such properties. Production stage mining rights represent interests in operating properties that contain proven and probable reserves. Development stage mineral interests represent interests in properties under development that contain proven and probable reserves.

Exploration stage mineral interests represent interests in properties that are believed to potentially contain mineralized material consisting of (i) mineralized material such as inferred material within pits; mineralized material with insufficient drill spacing to qualify as proven and probable reserves; and mineralized material in close proximity to proven and probable reserves; (ii) around-mine exploration potential not immediately adjacent to existing reserves and mineralization, but located within the immediate mine area; (iii) other mine-related exploration potential that is not part of current mineralized material and is comprised mainly of material outside of the immediate mine area; (iv) greenfield exploration potential that is not associated with any other production, development or exploration stage property, as described above; or (v) any acquired right to explore or extract a potential mineral deposit.

Exploration costs are capitalized when reserves at the location are established and reported in the Reserves and Resource information published annually by Newmont in its Form 10-K. At this point, exploration costs are capitalized as mine development or as a component of property, plant and equipment, as appropriate.

The Company’s mining rights generally are enforceable regardless of whether proven and probable reserves have been established. The Company has the ability and intent to renew mineral interests where the existing term is not sufficient to recover all identified and valued proven and probable reserves and (or) undeveloped mineralized material.

Mining rights are presented in the caption of property, plant and equipment, net.

F-138

Notes to the consolidated financial statements (continued)

(i)   Mine development costs -

Mine development costs include engineering and metallurgical studies, drilling and other related costs to delineate an ore body, and the removal of overburden to initially expose an ore body at open pit surface mines. Costs incurred before mineralization are classified as proven and probable reserves are expensed as “exploration and advanced projects” as part of the “Operating expenses” caption in the consolidated statements of comprehensive income. The capitalization of mine development project costs, that meet the definition of an asset, begins once mineralization is classified as proven and probable reserves.

Drilling and related costs are capitalized for an ore body where proven and probable reserves exist; and the activities are directed at obtaining additional information on the ore body or converting mineralized material to proven and probable reserves. AII other drilling and related costs are expensed as incurred. Drilling costs incurred during the production phase for operational ore control are allocated to inventory costs and then included as a component of the “Costs applicable to sales” caption in the consolidated statements of comprehensive income.

The cost of removing overburden and waste materials to access the ore body at an open-pit mine prior to the production phase are referred to as "pre-stripping costs." Pre-stripping costs are capitalized during the development of an open-pit mine. Where multiple open pits exist at a mining complex utilizing common processing facilities, pre-stripping costs are capitalized at each pit. The removal and production of the minimum saleable materials may occur during development and related revenue is recorded as “Other operating revenue”, net of incremental mining and processing costs. See note 2.4(i) below.

If any of the criteria are not met, the production stripping costs are charged to profit or loss as part of the “costs applicable to sales” caption in the consolidated statements of comprehensive income as they are incurred.

Mine development costs are amortized using the units-of production (UOP) method based on estimated recoverable ounces in proven and probable reserves. To the extent that these costs benefit an entire ore body, they are amortized over the estimated life of the ore body. Costs incurred to access specific ore blocks or areas that only provide benefit over the life of that area are amortized over the estimated life of that specific ore block or area.

Mine development costs are presented in the caption of Property, plant and equipment, net.

(j)    Stripping activity asset -

The Company accounts for stripping costs incurred during the production phase of a surface mining in accordance with IFRIC 20 “Stripping costs in the production phase of as surface mine” whereby a stripping asset is recognized if, and only if, all of the following are met:

-      It is probable that the future economic benefit (improved access to the ore body) associated with the stripping activity will flow to the Company;

-      The Company can identify the component of the ore body for which access has been improved; and

-      The costs relating to the stripping activity associated with that component can be measured reliably.

The primary components of the ore body on a pit by pit basis as well as within major pits are identified. Based on these components, stripping activities are analyzed, and costs are assigned based on whether they pertained to current inventory production or improved access to future ore bodies (or components of an ore body).

Based on this analysis, the Company allocates the costs associated with improved access as a “stripping activity asset”. This allocation is based on the volume of waste and ore extracted in the period compared to expected volume life-of-mine per component of ore body.

Costs allocated to the production stripping activity asset are subsequently depreciated. Depreciation of the production stripping asset was calculated on a systematic basis (waste-to-ore tons ratio) method over the expected useful life of the identified component of the ore body that becomes more accessible as a result of the stripping costs. This depreciation is a production cost.

F-139

Notes to the consolidated financial statements (continued)

(k)   Impairment of non-financial assets -

The carrying amounts of non-financial assets are reviewed for impairment whenever events or changes in circumstances indicate the carrying value may not be recoverable. If there are indicators of impairment, a review is undertaken to determine whether the carrying values are in excess of the recoverable amount. The recoverable amount is determined as the higher of (i) an asset’s fair value, less costs of disposal, and (ii) its value in use. Such review is undertaken on an asset by asset basis, except where such assets do not generate cash flows independently from other assets, in which case the review is undertaken at the cash generating unit level. The Company identified two separate cash generating units: Yanacocha and Conga.

Future cash flows are estimated based on quantities of recoverable minerals, expected gold and other commodity prices (considering current and historical prices, trends and related factors), production levels, operating costs, capital requirements and reclamation costs, all based on life-of-mine plans and the appropriate discount rate. These estimates, used in the determination of future cash flows, are based on numerous assumptions and it is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of recoverable minerals, gold and other commodity prices, production levels, costs and capital and interest rates are each subject to significant risks and uncertainties.

If the carrying amount of an asset exceeds its recoverable amount, an impairment loss is recorded in the consolidated statement of comprehensive income to reflect the asset at the lower amount. In assessing the recoverable amount for assets, the relevant future cash flows expected to arise from the fair value less costs to sell have been discounted to their present value.

An impairment loss is reversed in the consolidated statement of comprehensive income if there is a change in estimate used to determine recoverable amount since the prior impairment loss was recognized.

The carrying amount of an asset is increased to the recoverable amount but not beyond the carrying amount net of depreciation or amortization which would have arisen if the prior impairment loss had not been recognized. After such a reversal the depreciation charge is adjusted in future periods to allocate the asset’s revised carrying amount, less any residual value, on a systematic basis over its remaining useful life.

(l)   Intangible assets including computer software -

Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization (calculated on a straight-line basis over their useful lives).

The useful lives of intangible assets are assessed as either finite or indefinite.

Intangible assets with finite live are amortized over their useful economic lives and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the consolidated statements of comprehensive income in the expense category that is consistent with the function of the intangible assets. All intangible assets of the Company have finite lives.

Gains or losses arising from derecognition of an intangible asset are measured as the difference between the net disposal proceeds and the carrying amount of the asset and are recognized in the statements of comprehensive income when the asset is derecognized.

For the years ended December 31, 2021, 2020 and 2019, the amortization amount of intangible assets amounted to US$2.9 million, US$3 million and US$3 million, respectively.

F-140

Notes to the consolidated financial statements (continued)

(m)   Provisions -

General -

Provisions are recognized when the Company has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. If the time value of money is significant, provisions are discounted using pre-tax rates, which reflect, when appropriate, the liabilities’ specific risks. The reversal of the discount due to the passage of time originates the increase of the obligation which is recognized with a charge to the consolidated statements of comprehensive income as a finance cost.

Provisions are reviewed periodically and are adjusted to reflect the best estimate available as of the date of the consolidation statements of financial position. The expenses related to other provisions are presented in the consolidated statements of comprehensive income.

Disclosure of contingent obligations is provided when their existence will only be confirmed by future events or their amount cannot be reliably measured. Contingent assets are not recognized and are disclosed only if it is probable that the Company will generate future economic benefits.

Provision for mine closure -

The Company records a provision for mine closure when a legally enforceable obligation arises, which is independent of the full depletion of the mine reserves.

Provisions for mine closure or “reclamation obligations” are recognized when incurred and recorded as liabilities at the best estimate of the expenditure required to settle the obligation.

The Company recognizes a liability for closure of mining units once the obligation has been properly measured. The liability is initially recognized at the present value of the estimated costs. The liability is accreted over time for the change in present value based on discounted rates that reflects current market assessments and the risk specify to the liability through periodic charges to earnings. In addition, the asset retirement cost is capitalized as part of the asset's carrying value and amortized over the life of the related asset as “asset retirement and mine closure” or “reclamation costs” as part of the property, plant and equipment caption. Reclamation costs are periodically adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the timing or amount of the reclamation costs. The estimated reclamation obligation is based on when spending for an existing disturbance is expected to occur. The Company reviews, on an annual basis, unless otherwise deemed necessary, the reclamation obligation at each mine site.

Changes in the estimated timing of closure or changes to the estimated future costs are dealt with prospectively by recognizing an adjustment to the provision for closure liability and a corresponding adjustment to the related mining asset. Any reduction in the provision for closure and, therefore, any deduction from the mining asset to which it relates, may not exceed the carrying amount of the mining asset. If it does, any excess over the carrying amount is taken immediately to the consolidated statements of comprehensive income.

If the change in estimate results in an increase in the provision for closure and, therefore, an addition to the carrying value of the mining asset, the Company considers whether this is an indication of impairment of the asset as a whole, and if so, the Company performs an impairment test.

Reclamation costs related to an inactive mine site are immediately recognized as expenses in the consolidated statements of comprehensive income.

(n)   Revenue from contracts with customers -

The Company is principally engaged in the business of producing gold and concentrated copper/silver. Revenue from contracts with customers is recognized when control of the goods is transferred to the customer at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods.

F-141

Notes to the consolidated financial statements (continued)

The Company has concluded that it is the principal in its revenue contracts because it typically controls the goods before transferring them to the customer.

Trade receivables (not subject to provisional pricing) are non-interest bearing and are generally on terms of 30 days.

The disclosures of significant accounting judgements, estimates and assumptions relating to revenue from contracts with customers are provided in note 3.

(i)    Contract balances -

Contract assets

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company performs by transferring goods or services to a customer before the customer pays consideration or before payment is due, a contract asset is recognized for the earned consideration that is conditional. The Company does not have any contract assets as performance and a right to consideration occurs within a short period of time and all rights to consideration are unconditional.

Trade receivables

A receivable represents the Company’s right to an amount of consideration that is unconditional.

Contract liabilities

A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays consideration before the Company transfers goods or services to the customer, a contract liability is recognized when the payment is made, or the payment is due (whichever is earlier). Contract liabilities are recognized as revenue when the Company performs under the contract.

As of December 31, 2021, the Company has received payments of US$17 million for Conga mill assets which has been classified as a contract liability, see note 10. As of December 31, 2020, there were no contract liabilities.

Cost to obtain a contract

The Company’s contracts do not involve any sales commissions because its contracts are globally negotiated by its Corporate. Therefore, the Company does not recognize any costs to obtain a contract.

(ii)  Sales of gold -

Gold sales relate to unrefined gold dore that is sold under spot sales contracts to banks (customer). The Company initially negotiate with the banks the quantity of gold bullion to be required which is delivered in terms of unrefined gold dore to a selected refiner (the refiner is not the customer). The performance obligation is satisfied once the shipment confirmation is issued at the time the refinery receives the gold dore, allowing payment from the banks to the Company in full in cash in accordance to contracts with the banks.

All risk of loss and damage of the gold dore passes to the ground transportation upon reception; however, control of the product does not pass to the refiner, it is simply providing processing services to the Company.

The Company has identified only one performance obligation related to the sale of gold dore.

Revenue is recognized at a point in time when control passes to the bank, which is when the payment is ensured at the same time when the refinery’s shipment confirmation is issued to the bank. This generally occurs after the dore’s refinery shipments are confirmed, not being required to physically delivered the gold dore to the banks but resides in the mint. However, the bank has title, is required to pay for the gold bullion and is able to direct the use of the gold bullion by instructing the refiner to transfer metal credits to or from its metal account, and is exposed to the risks and rewards of the gold bullion.

F-142

Notes to the consolidated financial statements (continued)

The date of shipment’s confirmation and delivery might be different arising differences between the prices used. Therefore, these sales are subject to subsequent adjustments due the variation of assays. All these matters are resolved according a settlement process specified in the contract which result in the issue of debit/credit notes according to the assays results.

With these arrangements, there are no advance payments received from the banks, no conditional rights to consideration, so no contract assets are recognized. A trade receivable is recognized at the date of sale and it is usually paid on cash once delivery confirmation is issued. The contract is entered into and the transaction price is determined at outturn by virtue of the shipment confirmation being subject to further price adjustments when difference between delivery and shipment dates arises. Also, given each spot sale represents the enforceable contract and all performance obligations are satisfied at that time, there are no remaining performance obligations (unsatisfied or partially unsatisfied) requiring disclosure.

(iii) Sales of copper and silver concentrate -

Copper and silver in concentrate are sold under Free on Board (FOB) Incoterm and this represents the enforceable contract. The Company considers whether there are other commitments in the contract that involve separate performance obligations to which a portion of the transaction price must be allocated. The performance obligation is the delivery of the concentrate at the point where control passes to the customer.

The majority of the Company’s sales of copper and silver in concentrate allow for price adjustments based on the market price at the end of the relevant quotation period (QP) stipulated in the contract. These are referred to as provisional pricing arrangements and are such that the selling price for metal in concentrate is based on prevailing spot prices on a specified future date after shipment to the customer. Adjustments to the sales price occur based on movements in quoted market prices up to the end of the QP. The period between provisional invoicing and the end of the QP can be between one and three months.

Revenue is recognized when control passes to the customer, which occurs at a point in time when the copper, silver in concentrate is physically transferred onto a vessel, train, conveyor or other delivery mechanism. The revenue is measured at the amount to which the Company expects to be entitled, being the estimate of the price expected to be received at the end of the QP, i.e., the forward price, and a corresponding trade receivable is recognized.

For these provisional pricing arrangements, any future changes that occur over the QP are embedded within the provisionally priced trade receivables and are, therefore, within the scope of IFRS 9 and not within the scope of IFRS 15. Given the exposure to the commodity price, these provisionally priced trade receivables will fail the cash flow characteristics test within IFRS 9 and will be required to be measured at fair value through profit or loss up from initial recognition and until the date of settlement. These subsequent changes in fair value are recognized in the consolidated statements of comprehensive income and other comprehensive income each period and presented in “Other operating revenue”. Changes in fair value over, and until the end of, the QP, are estimated by reference to updated forward market prices for gold and copper as well as taking into account relevant other fair value considerations as set out in IFRS 13, including interest rate and credit risk adjustments.

Revenue is recognized at the amount the entity expects to be entitled. The price expected to be received at the end of the quotation period is generally set at the month of shipment or delivery according to the terms of the contracts, using the most recently determined estimate of metal in concentrate (based on initial assay results) and the estimated forward price. The requirements in IFRS 15 on constraint estimates of variable consideration are also applied to determine the amount of variable consideration that can be included in the transaction Price. Sales for copper, silver and the subsequent changes in fair value of the trade receivable are presented in the caption “Other operating revenue”.

(iv)  Interest income 

For all financial instruments measured at amortized cost, interest income is recorded using the effective interest rate (EIR). EIR is the rate that exactly discounts the estimated future cash payments or receipts over the expected life of the

F-143

Notes to the consolidated financial statements (continued)

financial instrument or a shorter period, where appropriate, to the net carrying amount of the financial asset or liability. Interest income is included in finance income in the consolidated statements of comprehensive income.

As of December 31, 2021 and 2020 this caption mainly includes interest from short-term money market funds and interest from current bank accounts for an amount of US$1,000 and US$8,100, respectively.

(o)  Benefits to employees -

In accordance to Peruvian laws, employees are entitled to receive one month paid vacation per year and one-month salary bonus paid in July and December.

In addition, employees are entitled to receive one -month salary per year (approximately) as severance indemnity which are deposited in advance with a bank elected by the employee.

If employees are dismissed without cause, they are entitled to a mandatory severance pay that is set at 1.5 monthly salaries for each year of service. The maximum severance payment is twelve salaries.

Salaries and wages, bonuses, post-employment benefits and vacations are calculated in accordance with IAS 19, "Employee Benefits" and are calculated in accordance with current Peruvian legislation based on the accrual basis.

(p)  Workers’ profit sharing -

The Company recognizes workers’ profit sharing in accordance with IAS 19, “Employees Benefits". Workers' profit sharing is calculated in accordance with the Peruvian law (Legislative Decree No. 892), and the applicable rate is 8% over the taxable net base of current year. According to Peruvian law, the limit in the workers' profit sharing that an employee can receive is equivalent to 18 months of wages, and any excess above such limit has be transferred to the Regional Government and “National Fund for Employment’s Promotion and Training” (FONDOEMPLEO). The workers’ profit sharing is recorded as part of cost applicable to sales, see note 19.

(q)  Taxes -

Current income tax -

Current income tax assets and liabilities for the current and prior periods are measured at the amount expected to be recovered from, or paid to, the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date in Peru.

Current income tax relating to items recognized directly in other comprehensive income or equity is recognized in other comprehensive income or equity and not in profit or loss. Management periodically evaluates positions taken in the tax returns with respect to situations where applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

Deferred income tax -

The Company accounts for income and mining taxes using the liability method, recognizing certain temporary differences between the financial reporting basis of the Company’s liabilities and assets and the related income tax basis for such liabilities and assets. This method generates a net deferred income tax liability or net deferred income tax asset for the Company, as measured by the statutory tax rates that have been enacted or substantively enacted by the end of the reporting period.

The Company derives its deferred income tax charge or benefit by recording the change in the net deferred income tax liability or net deferred income tax asset balance for the year, based on Peruvian income and mining tax laws.

Deferred income tax assets are recognized only to the extent that it is probable that future taxable profit will be available against which the temporary differences, and the carry-forward of unused tax credits can be utilized.

F-144

Notes to the consolidated financial statements (continued)

Deferred tax related to items recognized in other comprehensive income or equity is recognized in other comprehensive income or equity and not in profit or loss.

Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities where there is an intention to settle the balances on a net basis.

Peruvian mining royalties and special mining tax –

In accordance with Law No. 28258, as amended by Law No. 29788, mining royalties are payable as the higher of either as a specified percentage of (i) tax operating profit or (ii) 1% of revenues. If the mining royalty is calculated as a percentage of operating profit, marginal rates ranging from 1% to 12% that increase progressively for companies with higher operating margins will apply.

Mining royalties and special mining tax are accounted for in accordance with IAS 12 "Income Tax" because they have the characteristics of an income tax. This is considered to be the case when they are imposed under government authority and the amount payable is based on taxable income-rather than physical quantities produced or as a percentage of revenue-after adjustment for temporary differences. Legal rules and rates used to calculate the amounts payable are those in effect on the date of the consolidated statements of financial position.

Therefore, obligations arising from Mining Royalties and Special Mining Tax are recognized as income tax under the scope of IAS 12. Both, Mining Royalties and Special Mining Tax generated deferred tax assets and liabilities which must be measured using the average rates expected to apply to operating profit in the quarter in which the Company expects to reverse temporary differences.

Value added tax -

Expenses and assets are recognized net of the amount of sales tax, except:

(i)    When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable;

(ii)   When receivables and payables are stated with the amount of sales tax included. The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the consolidated statements of financial position.

The net amount to be recovered, or payable, to the Tax authority is included as a receivable or payable in the consolidated statements of financial position.

Uncertainty over Income Tax Treatment –

The Company determines whether it considers each uncertain tax treatment separately or in conjunction with one or more other uncertain tax treatments based on the approach that best predicts the resolution of the uncertainty.

The Company perform judgments and estimates when there is uncertainty regarding the income tax treatments.

The Company determined, based on its tax compliance and transfer pricing study, that its tax treatments are likely to be accepted by the tax authorities.

(r)   Fair value measurement -

The Company measures its financial instruments, such as, derivatives and embedded derivatives, at fair value as of the date of the consolidated statements of financial position.

F-145

Notes to the consolidated financial statements (continued)

Fair value is the price that would be received to sell an asset, or paid to transfer a liability, in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either:

-      In the principal market for the asset or liability, or

-      In the absence of a principal market, in the most advantageous market for the asset or liability.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the consolidated financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

-      Level 1 - Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

-      Level 2 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.

-      Level 3 - Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are recognized in the consolidated statements of financial position on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by reassessing categorization (based on the lowest-level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

The Company’s Management determines the policies and procedures for both recurring fair value measurement and non-recurring measurement. At each reporting date, the Company’s Management analyzes the movements in the values of assets and liabilities which are required to be re-measured or re-assessed as per the Company’s accounting policies.

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

(s)   Leases -

The Company assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

Company as a lessee

The Company applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Company recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets.

(i)   Right-of-use assets -

The Company recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term and the estimated useful lives of the assets, as follows:

- Buildings 5 to 10 years

- Plant and equipment 3 to 10 years

F-146

Notes to the consolidated financial statements (continued)

If ownership of the leased asset transfers to the Company at the end of the lease term or the cost reflects the exercise of a purchase option, depreciation is calculated using the estimated useful life of the asset.

The right-of-use assets are also subject to impairment. Refer to the accounting policies in section (j) “Impairment of non-financial assets”.

(ii)   Lease liabilities -

At the commencement date of the lease, the Company recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees.

The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company and payments of penalties for terminating the lease, if the lease term reflects the Company exercising the option to terminate. Variable lease payments that do not depend on an index or a rate are recognized as expenses (unless they are incurred to produce inventories) in the period in which the event or condition that triggers the payment occurs.

In calculating the present value of lease payments, the Company uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is re-measured if there is a modification, a change in the lease term, a change in the lease payments (e.g., changes to future payments resulting from a change in an index or rate used to determine such lease payments) or a change in the assessment of an option to purchase the underlying asset.

The Company’s lease liabilities are included in other accounts payable.

(iii) Short-term leases and leases of low-value assets -

The Company applies the short-term lease recognition exemption to its short-term leases of machinery and equipment (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered to be low value. Lease payments on short-term leases and leases of low value assets are recognized as expense on a straight-line basis over the lease term.

3.     Significant judgments, estimates and assumptions

The preparation of the Company’s consolidated financial statements requires Management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. The estimates and assumptions are continuously evaluated and based on Management’s experience and other facts, including the expectations about future events which are reasonable under the current situation. Uncertainty about these estimates and assumptions could result in outcomes that require material adjustment to the carrying amount of assets and liabilities affected in future periods. Further information on each of these areas and how they impact the various accounting policies are described below and also in the relevant notes to the consolidated financial statements.

3.1.  Judgments

In the process of applying the Company’s accounting policies, Management has made the following judgments, which have the most significant effect on the amounts recognized in the consolidated financial statements:

(a)  Contingencies -

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential quantum of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

F-147

Notes to the consolidated financial statements (continued)

(b)  Development start date -

The Company assesses the status of each exploration project to determine when the development phase begins. One of the criteria used to evaluate the development start date is when the Company determines that the property can be economically developed based on the results of feasibility studies.

(c)  Production start date -

The Company assesses the stage of each mine under development to determine when a mine moves into the production phase. The determination of the start date is based on the unique nature of each mining project; such as the complexity of the project and its location. The Company considers various relevant criteria to assess when the production phase is considered to have commenced. Some of the criteria used to identify the production start date include, but are not limited to:

-      Completion of a reasonable period of testing of the mine plant and equipment.

-      Ability to produce metal in saleable form (within specifications).

-      Ability to sustain ongoing production of metal.

When a mine development /construction project moves into the production phase, the capitalization of certain mine development costs ceases and the cost of mining waste ore are either regarded as forming part of the cost of inventory or expensed, except for costs that qualify for capitalization relating to mining asset additions or improvements. It is also at this point that depreciation or amortization commences.

(d)  Useful life of property, plant and equipment -

Depreciation is calculated under the straight-line method of accounting considering the lower of estimated useful lives of the assets or estimated reserves of the mining unit. See Note 2.4 (g) for useful lives.

(e)  Revenue from contracts with customers -

The Company applied the judgement for determining the timing of satisfaction of services of revenue from contracts with customers. The Company concluded that the performance obligation is completed once the shipment confirmation is issued when the refinery receives the dore, allowing the fully payment in cash according the contracts. As a result, all risk of loss and damage of the gold dore pass to refiner upon reception.

The Company determined that the only performance obligation is the sale of gold dore.

3.2.  Estimates and assumptions -

The key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Company based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market change or circumstances arising beyond the control of the Company. Such changes are reflected in the assumptions when they occur.

(a)   Determination of mineral reserves and resources -

The Company calculates its reserves using methods generally applied by mining and industry according to SEC guidance. All estimated reserves represent estimated quantities of mineral proven and probable that under current conditions can be economically and legally processed.

The process of estimating quantities of reserves is complex and requires making subjective decisions when evaluating all geological, geophysical, engineering and economic information available. Reviews could occur on reserve estimates due to, among others, revisions to the data or geological assumptions, changes in prices, production costs and results of exploration activities. Changes in estimated reserves could affect the carrying value of mining concessions, development costs and property, plant and equipment, the charges in result for depreciation and amortization, and the carrying amount of the provision for mine closure.

F-148

Notes to the consolidated financial statements (continued)

(b)  Units of production depreciation -

Estimated economically recoverable reserves are used in determining the depreciation and (or) amortization of mine-specific assets.

This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. Each mine’s life is assessed at least annually to evaluate (i) physical life limitations and (ii) present assessments of economically recoverable reserves of the mine property. These calculations require the use of estimates and assumptions, including the amount of recoverable reserves. Changes in estimates are accounted for prospectively.

(c)  Provision for mine closure -

The Company assesses its provision for mine closure at each reporting date. The ultimate rehabilitation costs are uncertain, and cost estimates can vary in response to many factors, including estimates of the extent and costs of closure activities, technological changes, regulatory changes, cost increases as compared to the inflation rates, and changes in discount rates. These uncertainties may result in future actual expenditure differing from the amounts currently provided. The provision at reporting date represents Management’s best estimate of the present value of the future closure costs required.

(d)  Inventories -

Inventories are classified as current or non-current depending on the length of time that Management estimates will be used in the production or extraction for each mining unit.

Inventories are measured at the lower of its weighted average cost or its net realizable value. Net realizable value tests are performed at each reporting date and represent the estimated future sales price of the product the entity expects to realize when the product is processed and sold, less estimated costs to complete production and bring the product to sale.

Stockpiles and ore on leach pads are measured by estimating the number of tons added and removed from the stockpile and leach pads, the number of contained gold ounces, assay data, and the estimated recovery percentage based on the expected processing method. Stockpile and ore on leach pad tonnages are verified by periodic surveys.

For minerals inside leach platform inventories, reasonable estimation methods are employed because it is generally impracticable to determine the mineral contained in leach platforms by physical count. The quantity of material delivered to leach platforms are based on surveyed volumes of mined material and daily production records. Sampling and assaying determine the estimated ore grades of material delivered to leach platforms.

(e)  Impairment and reversal of non-financial assets -

The Company assesses each asset or cash generating unit in each reporting period to determine whether any indication of impairment exists or the reversal of impairment previously recorded (e.g., fluctuation of gold prices, community relations and social license to operate). Where an indicator of impairment exists, a formal estimate of the recoverable amount is made, which is considered to be the higher of (i) the fair value less costs of disposal and (ii) value in use. The assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates and operating costs, among others. These estimates and assumptions are subject to risk and uncertainty.

The fair value of mining assets is calculated by the present value of future cash flows arising from the continued use of the asset, which include some estimates, such as the cost of future expansion plans, using assumptions that a third party might consider. The future cash flows are discounted to their present value using a discount rate that reflects current market assessment of the value of money over time, as well as specific risks of the asset or cash-generating unit under evaluation.

The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceed the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statement of profit or loss unless the asset is carried at a revalued amount, in which case, the reversal is treated as a revaluation increase.

F-149

Notes to the consolidated financial statements (continued)

The Company has determined the operations of its mining units Yanacocha and Conga as its cash generating units.

4.     Standards issued but not effective

The new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Company’s consolidated financial statements are disclosed below. The Company intends to adopt these new and amended standards and interpretations, if applicable, when they become effective.

Amendments to IAS 1: Classification of Liabilities as Current or Non-current

In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classifying liabilities as current or non-current. The amendments clarified:

- What is meant by a right to defer settlement.

- That a right to defer must exist at the end of the reporting period.

- That classification is unaffected by the likelihood that an entity will exercise its deferral right.

- That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification.

The amendments are effective for annual reporting periods beginning on or after January 1, 2023 and must be applied retrospectively.

Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16

In May 2020, the IASB issued Property, Plant and Equipment — Proceeds before Intended Use, which prohibits entities deducting from the cost of an item of property, plant and equipment, any proceeds from selling items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss.

The amendment is effective for annual reporting periods beginning on or after January 1, 2022 and must be applied retrospectively to items of property, plant and equipment made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment. The amendment will not have an impact on the consolidated financial statements.

Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37:

In May 2020, the IASB issued amendments to IAS 37 to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making.

The amendments apply a “directly related cost approach”. The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract.

The amendments are effective for annual reporting periods beginning on or after January 1, 2022. The Company will apply these amendments to contracts for which it has not yet fulfilled all its obligations at the beginning of the annual reporting period in which it first applies the amendments.

F-150

Notes to the consolidated financial statements (continued)

IFRS 9 Financial Instruments: '10 percent 'test fee for derecognition of financial liabilities:

As part of its 2018-2020 annual improvement process to IFRS, the IASB issued an amendment to IFRS 9. The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different. of the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by the borrower or lender on behalf of the other. An entity applies the amendment to financial liabilities that are amended or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment.

The amendment is effective for annual reporting periods beginning on or after January 1, 2022 and early adoption is permitted. The Company will apply the modifications to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the Company applies the modification for the first time.

Management has evaluated the impact and expects that these modifications will not have a significant impact on the Company's consolidated financial statements.

9.    Financial instruments at fair value

In November 2008, the Company funded the San Jose Reservoir Trust an amount of US$13 million to ensure the continuity of the Company’s operations in the San Jose Reservoir after 2018. Such trust is irrevocable and is a separate legal entity of the Company. The grantor is the Company, the trustee is the Banco de Crédito del Perú and the beneficiary is the Company; therefore, the Company consolidates the trust.

As of December 31, 2021 and 2020, the assets in the trust amount to US$24,459 and US$25,168, respectively and are represented by financial instruments at fair value.

During the years ended December 31, 2021, a decrease in fair value of the debt instruments was recognized in other comprehensive loss for US$642, an increase of US$123 and US$1,246 during 2020 and 2019 respectively. During the years ended December 31, 2021 and 2020 the change in fair value of the investments in marketable stocks for US$ (849) and US$(207) respectively, were recognized as “Finance income and Finance costs” in the consolidated statements of comprehensive income.

10.   Assets held for sale

During 2021, the Company entered into a binding agreement to sell certain equipment and assets for the Conga project, for total cash proceeds of US$68 million , net of associated cost for sale for US$46 million. The book value of these assets before classification as held for sale was US$174 million (includes [i] the book value of assets included in the sales agreement for US$79 million and [ii] book value of services and other assets capitalized for US$95 million), accordingly, the Company recognized an expense of US$152 million. Pursuant to the terms of the agreement, the sale is expected to close upon delivery of the assets and receipt of the final payment at which time title and control of the assets will transfer, currently expected to occur within approximately one year. As of December 31, 2021, the Company has collected US$17 million as part of the initial payment of the transaction included in "Other current liabilities", see note 13.

Upon entering the binding agreement, the Conga mill assets have been reclassified as held for sale, included in Assets held for sales on the Consolidated statement of financial position as of December 31, 2021, and measured at its fair value less costs to sell. As of December 31, 2021, the value of assets held for sale is US$22 million.

Subsequent to the loss recognized, the remaining total assets at Conga as of December 31, 2021 amounted approximately to US$262 million. As of December 31, 2021, the Company has not identified events or changes in circumstances that indicate that the remaining carrying value of the Conga project is not recoverable. Although the Company has entered into the binding agreement to sell the Conga mill assets, it will continue to evaluate long-term options to progress development of the Conga project.

Additions to work in progress is primarily related to development of the Sulfides Project in 2021 and 2020. As of December 31, 2021, the Company does not have material commitments related to these projects.

The depreciation and amortization expense for the year ended December 31, 2021 and 2020 was recorded in the “Cost applicable to sales” caption in the consolidated statement of comprehensive income.

(b) Impairment of long-lived assets -

In accordance with the accounting policies and processes, each asset or Cash Generating Unit “CGU” is evaluated annually at year end, to determine whether there are any indications of impairment. If any such indications of impairment exist, a formal estimate of the recoverable amount is performed. The Company has two CGU’s: Yanacocha mine and the Conga project.

In December 2021, the Company performed a formal evaluation of its cash generating units and concluded that there are indicators of reversal of impairment of its Yanacocha CGU, therefore it determined the recoverable value of this CGU. As a result of this analysis for Yanacocha, the Company concluded that a reversal of impairment loss required as the recoverable amount was higher than the carrying amount of the CGU’s assets mainly explained for the increase of the gold prices and the near development of the Sulfides project.

In assessing whether impairment or reversal of impairment was required, the carrying value of the asset or CGU was compared with its recoverable amount. The recoverable amount is the higher of (i) the CGU’s fair value less costs of disposal (FVLCD) and (ii) value in use (VIU). Given the nature of the Company’s activities, information on the fair value of an asset is usually difficult to obtain unless negotiations with potential purchasers or similar transactions are taking place. The recoverable amount for Yanacocha was estimated based on the FVLCD using estimated future cash flows expected to be generated from the continued use of the CGUs. The recoverable amount for Conga was estimated based on estimated discounted future estimated cash flows expected to be generated from the continued use of the CGUs using market-based commodity price and exchange assumptions, estimated quantities of recoverable minerals, production levels, operating costs

and capital requirements, and its eventual disposal, based on the latest life of mine (LOM) plans. These cash flows were discounted using a real pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU.

Estimates included quantities of recoverable minerals, production levels, operating costs and capital requirements and sourced from the planning process, including the LOM plans, business plan and CGU-specific studies.

Key assumptions used for the impairment testing as of December 31, 2021:

Yanacocha:

The recoverable amount for the Yanacocha CGU was based on the FVLD using estimated future cash flows expected to be generated from the continued use of the CGUs using market assumptions. Based on the fair value calculated, the Company recognized an impairment reversal on Yanacocha of US$97.6 million.

Yanacocha:

The determination of FVLD was most sensitive to the following key assumptions:

-      Production volumes.

-      Commodity prices.

-      Discount rate.

-      Cost/operating income

Production volumes: Estimated production volumes are based on detailed life-of-mine plan and take into account development plans for the mine agreed by management as part of planning process. Production volumes are dependent on a number of variables, such as: the recoverable quantities; the production profile; the cost of the development of the infrastructure necessary to extract the reserves; the production costs; the contractual duration of mining rights; and the selling price of the commodities extracted.

As each producing mining unit has specific reserve characteristics and economic circumstances, the cash flows of the mine were computed using an appropriate individual economic model and key assumptions established by management. The production profile used was consistent with the reserves and resource volumes approved as part of the Company’s process for the estimation of proved and probable reserves and resource estimates.

Commodity prices: Forecasted commodity prices were based on management’s estimates and were derived from forward price curves and long-term views of global supply and demand, building on past experience of the industry and consistent with external sources. These prices were adjusted to arrive at appropriate consistent price assumptions for the different qualities and type of commodities, or, where appropriate, contracted prices were applied.

Estimated prices for the long-term period used to estimate future revenues were as follows:

2021	Long-term
	US$
Gold (per ounce)	1,800
Silver (per ounce)	23
Copper (per pound)	3.05

F-157

Notes to the consolidated financial statements (continued)

2020	Long-term
	US$
Gold (per ounce)	1,500
Silver (per ounce)	16
Copper (per pound)	3.00

Discount rate: In calculating the value in use, a pre-tax discount rate in a range of 8.40% to 9.60% was applied to the Conga pre-tax cash (9.38% to 10.36% as of December 31, 2020). This discount rate was derived from the Company’s pre-tax weighted average cost of capital (WACC), with appropriate adjustments made to reflect the risks specific to the CGU.

Sensitive Analysis

During 2021, When determining the value-in-use of the CGUs’ Conga, management estimated a pre-tax discount rate between 8.9%-9.4%, and 9.4%-10.4%, respectively. WACC is a key assumption in the determination of the recoverable amounts, and changes in WACC would impact the recoverable amounts as follows:

Regarding CGU Conga, the Company concluded that no reversal of impairment loss was appropriate, despite that recoverable amount of the CGU's assets was higher than the carrying amount, due to the sensitivity of the Conga project to the social and politic conflicts.

Non-current portion	2,393,956	1,660,603
	2,535,684	1,762,389

(b) Provision for mine closure and explorations projects -

The Company’s mining and exploration activities are subject to various laws and regulations governing the protection of the environment. These laws and regulations are continually changing and are generally becoming more restrictive. The Company conducts its operations so as to protect the public health and environment and believes its operations are in compliance with all applicable laws and regulations in all material respects. The Company has made, and expects to make in the future, expenditures to comply with such laws and regulations, but cannot predict the amount of such future expenditures. Estimated future reclamation costs are based principally on legal and regulatory requirements.

The provision for mine closure comprises activities to be carried out by the Company in the restoration of mines and adjacent areas in the completion stage of the gold extraction process. Such activities include the restoration of mining locations, water treatment plant operations, as well as reforestation and land treatments.

The movement of the provision for mine closure for 2021, 2020 and 2019 is broken down as follows:

	2021	2020	2019
	US$(000)	US$(000)	US$(000)

	2,515,914	1,738,428	1,608,380

The provision for mine closure and exploration projects represents the present value of the closure costs that are expected to be incurred between the years 2022 and 2071.

There were minimal changes to the updated closure plan in 2017 prior to submitting to Peruvian regulators in September 2017. The regulators completed their review and approved the updated closure plan in November 2017.

F-159

Notes to the consolidated financial statements (continued)

During the years ended December 31, 2021, 2020 and 2019, the Company recorded an increase to the reclamation liability of US$815 million, US$121 million and US$301 million, respectively. The update to the reclamation obligation resulted in an decrease to the recorded asset retirement cost asset of US$7.9 million (US$4 million decrease and US$159 million increase in 2020 and 2019, respectively) related to the producing portions of the mine (see note 11) and a non-cash charge to reclamation expense for the year ended December 31, 2021 of US$823 million (US$124 million and US$142 million as December 31, 2020 and 2019, respectively) related to the areas of Carachugo, Yanacocha, Maqui Maqui and Cerro Negro operations no longer in production (see note 19). The increase of the 2021 reclamation obligation is mainly due to the expected construction of two water treatment plants, a related increase in the annual operating costs over the extended closure period, and initial consideration of known risks (including the associated risk that these water treatment estimates could change in the future as more work is completed), whereas in 2020 the increase was mainly due to higher water treatment costs. The discount rates used in the calculation of the provision as December 31, 2021, 2020 and 2019 were between 0.4% and 6.0%.

(c) Provision of social responsibility -

The provision of social responsibility relates to community commitments to develop projects near the mine site, including training and support for other activities such as building infrastructure and donations.

15.   Debt instruments

On June 14, 2018, the Company approved the sale of 63,922,565 shares of Minera Yanacocha, S.R.L. to Summit Global Management II BV, a wholly-owned subsidiary of Sumitomo Corporation (Sumitomo) for a consideration of US$47,911. The transaction resulted in Sumitomo owning 5% of Minera Yanacocha, S.R.L. with Newmont Second Capital Corporation and Buenaventura’s ownership percentages decreasing to 51.35% and 43.65%, respectively.

Under the terms of the transaction, Sumitomo has the option to require the Company to repurchase the 5% interest in Minera Yanacocha, S.R.L. if the Yanacocha Sulfides project does not adequately progress by June 2022 or if the project is approved with an incremental rate of return below a contractually agreed upon rate. Under the terms of the sales agreement, the cash paid by Sumitomo at closing has been placed in an escrow for repayment in the event the option is exercised. As of December 31, 2021 and December 31, 2020, the Company holds US$48,752 in an escrow account with Citibank New York and generates interest at a market rate. This balance is included in the caption Restricted Cash in the consolidated statement of financial position. The restricted cash is not available to finance the Company's day-to-day operations and, therefore, has been excluded from cash and cash equivalents for the purposes of the consolidated statement of cash flows. It has been disclosed as a non-current asset.

The shares held by Sumitomo meet the definition of a compound instrument and is classified as a liability (with a portion recorded to equity) in the consolidated financial statements of the Company. The difference between the present value of the compound instrument at the date of the transaction for an amount of US$41,695 and the gross redemption amount of US$47,911 was recorded as additional paid-in-capital in equity for an amount of US$6,216 at the date of the transaction.

The value of the compound instrument as of December 31, 2021 and December 31, 2020 amounts to US$47,080 and US$45,423, respectively. For the years ended December 31, 2021, 2020 and 2019 the unwinding of the discount was recognized in the caption “Finance costs” in the consolidated statement of comprehensive income for an amount of US$1,497, US$1,497 and US$1,497, respectively, see note 23.

Pursuant to this legislation, the mining royalty is payable quarterly based on sales and operating profit. The royalty amount due is 1% of revenue. An additional mining tax due is calculated based on the level of operating profit up to a maximum applicable rate of 12%. This component of the new mining tax only applies to those projects that are not covered by a tax stabilization agreement. During 2021, 2020 and 2019, the amounts included in cost of production related to mining royalties were US$5,266, US$6,167 and US$7,360, respectively. During 2021,2020 and 2019, the amount included in mining tax expense related to mining royalties were US$2,353, US$55 and US$1,563, respectively.

24.  Commitments and contingencies

Unitization of properties -

In December 2000, as a result of the unitization plan carried out by the Partners, the Company signed several asset transfer and mining usufruct agreements with related entities. The main conditions are:

-      The Company must pay to Chaupiloma, 3% of the quarterly net sales, according to the lease agreement. The mining rights subject to this 3% royalty are those identified in the lease agreement as part of the “Area of Influence of Chaupiloma”. Some of these mining rights are in exploitation and the rest of them in exploration.

-      The Company must pay to Los Tapados S.A., 3% of the quarterly net sales proceeds of mineral extracted from the transferred and leased concessions of Los Tapados S.A. The transferred and leased concessions of Los Tapados S.A. are also subject to a previously existing royalty on the minerals. These mining rights are in exploitation and others inactive.

Legal proceedings -

Conga project Constitutional claim -

On October 18, 2012, Marco Antonio Arana Zegarra filed a constitutional claim against the Ministry of Energy and Mines and Yanacocha requesting the Court to order the suspension of the Conga project as well as to declare not applicable the October 27, 2010, directorial resolution approving the Conga project Environmental Impact Assessment (“EIA”). On October 23, 2012, a Cajamarca judge dismissed the claims based on formal grounds finding that: (i) plaintiffs had not exhausted previous administrative proceedings; (ii) the directorial resolution approving the Conga EIA is valid, and was not challenged when issued in the administrative proceedings; (iii) there was inadequate evidence to conclude that the Conga project is a threat to the constitutional right of living in an adequate environment; and (iv) the directorial resolution approving the Conga project EIA does not guarantee that the Conga project will proceed, so there was no imminent threat to be addressed by the Court. The plaintiffs appealed the dismissal of the case. The Civil Court of the Superior Court of Cajamarca confirmed the above mentioned resolution and the plaintiff presented an appeal. On March 13, 2015, the Constitutional Court published its ruling stating that the case should be sent back to the first court with an order to formally admit the case and start the judicial process in order to review the claim and the proofs presented by the plaintiff. Yanacocha has answered the claim. The Company can not reasonably predict the outcome of this litigation

The Company has not established a provision in the accompanying consolidated financial statements for a loss arising from this contingency, which it does not consider probable.

Open tax procedures -

For the periods pending of examination, due to The Tax Authority has the right to examine, and, if necessary, amend the Company’s income tax provision for the last four years. The Company’s income tax filings for the years 2016 through 2021 are open to examination by the tax authorities. However, due to the fact that SUNAT could not carry out its inspection tasks during the quarantine period, the calculation of the statute of limitations was suspended; In this sense, the prescription for the period 2016 would expire the last week of March 2022, approximately. For value added tax, the periods open for examination are December 2017 through 2021. Regarding the referred quarantine period, the calculation of the statute of limitations related to the value added tax also was suspended; in this sense, the prescription of the period between December 2016 to November 2017 would expire the last week of March 2022, approximately. To date, National Tax Supervisor “SUNAT” has concluded its review of the Company’s tax exams through the year 2014.

Due the many possible interpretations of current legislation, it is not possible to determine whether or not future reviews will result in tax liabilities for the Company. In the event that additional taxes are payable, including interest and surcharges, as a result of the Tax Authority reviews, they will be charged to expense in the period assessed. However, in Management’s and legal advisors’ opinion, any additional tax assessment would not be significant to the consolidated financial statements.

Tax Dispute related to the amortization of the contractual rights -

In 2000, Yanacocha paid Buenaventura and Minas Conga S.R.L. a total of US$29 million to assume their respective contractual positions in mining concession agreements with Chaupiloma Dos de Cajamarca S.M.R.L. The contractual rights allowed Yanacocha the opportunity to conduct exploration on the concessions, but not a purchase of the concessions. The tax

F-169

Notes to the consolidated financial statements (continued)

authority alleges that the payments to Buenaventura and Minas Conga S.R.L. were acquisitions of mining concessions requiring the amortization of the amounts under the Peru Mining Law over the life of the mine. Yanacocha expensed the amounts at issue in the initial year since the payments were not for the acquisition of a concession but rather these expenses represent the payment of an intangible and therefore, amortizable in a single year or proportionally for up to ten years according to Income Tax Law. In 2010, the tax court in Peru ruled in favor of Yanacocha and the tax authority appealed the issue to the judiciary. The first appellate court confirmed the ruling of the tax court in favor of Yanacocha. However, in November 2015, a Superior Court in Peru made an appellate decision overturning the two prior findings in favor of Yanacocha. Yanacocha has appealed the Superior Court ruling to the Peru Supreme Court. On January 18, 2019, the Peru Supreme Court issued notice that three judges support the position of the tax authority and two judges support the position of Yanacocha. Because four votes are required for a final decision, an additional judge was selected to issue a decision and the parties conducted oral arguments in April 2019. In February 2020, the additional judge ruled in favor of the tax authority, finalizing a decision of the Peru Supreme Court against Yanacocha. As a result of the decision, the Company recognized the amount of US$29 million in 2020. However, Yanacocha filed two constitutional actions in 2020, and one legal claim in 2021, objecting to potential excessive interest and duplicity of criteria of up to US$50 million, US$ 73 million,and US$ 68 million, respectively.

In March 2021, in one of the constitutional actions, Yanacocha’s request for an injunction to suspend the collection of interest, which was denied. The matter was sent back to the tax authority, which issued a resolution with an update of the total amount. Yanacocha appealed the tax authority’s resolution and, in October 2021, the tax court denied the appeal. As a result, the administrative case went back to the tax authority for collection and the Company paid the amount claimed due in October 2021 of approximately US$80 million and recognized as finance costs by US$55 million for the year ended December 31, 2021, see note 23. In January 2022, Yanacocha filed a fourth legal claim, objecting to the amount of up to US$72 million. The Company continues to pursue the legal actions that remain pending, seeking to recover up to US$73 million of the total amount paid based on current exchange rates, but it is not possible to fully predict the outcome of such litigation.

Notes to the consolidated financial statements (continued)

For the years ended December 31, 2021 and 2020, there is no allowance for expected credit losses related to related parties accounts.

26.  Financial - risk management objectives and policies

The Company’s operations are exposed to certain financial risks: some market risks (foreign exchange risk, interest rate risk and price risk, credit risk and liquidity risk). The Company’s overall risk management program focuses on the unpredictability of financial markets and seeks to minimize potential adverse effects on the Company’s financial performance. The most important aspects in risk management are the following:

(a)Market risks -

(i) Foreign exchange risk -

Foreign exchange risk exposure arises from exchange rate fluctuations of balances denominated in different currencies than the U.S. dollar. Since transactions and balances denominated in foreign currency are not significant, the current exchange rate risk exposure is limited. Management has decided to assume the exchange risk exposure with the results of the Company’s operations; therefore, it has not engaged in hedging activities.

(ii) Interest rate risk -

The Company does not maintain significant interest-bearing assets or liabilities; therefore, net income (loss) and cash flows of the Company are substantially independent from the changes in market interest rates.

(iii) Price risk -

The Company's financial instruments exposed to price risk are limited to its trade accounts receivable (exposed to gold price) and its available-for-sale financial assets, none of which show a material balance at the end of year, therefore no significant impact on the consolidated financial statements has arisen due to changes in their price that would need to be disclosed.

(b) Credit risk -

The Company evaluates the concentration of risk with respect to trade receivables as low, as its customers are located in Canada and operate in largely independent markets. The Company's products (refined gold dore) are negotiated in international markets being subject to the global demand, as a result it does not concentrate risks related to limited number of clients. The Company counts with counterparties with high credit-rating, and have not had any significant default event arising from risk concentration.

Credit risk is managed on a group basis by Newmont according to its policies. Financial instruments exposed to credit risk are cash and cash equivalents, investments in debt and equity instruments, trade accounts receivable and other accounts receivable. For banks and financial institutions, only independently rated parties with a minimum "A" rating are accepted. Regarding trade accounts receivable, according to the practice in the latest years, collections have generally been in full. A credit review of the portfolio is performed quarterly to determine any deterioration in credit quality. The Company does not foresee any significant losses that may arise from this risk.

(c) Liquidity risk -

Management administrates its exposure to liquidity risk through financing from internal operations, Company’s partners and maintaining good relationships with local and foreign banks in order to maintain adequate levels of credit available. The Company currently has no existing bank lines of credit.

The following table represents the analysis of the Company’s financial liabilities, considering the remaining period to reach such maturity as of the consolidated statement of financial position date (see notes 13 and 14):

Notes to the consolidated financial statements (continued)

(d) Capital risk management -

The Company’s objectives for managing capital are to safeguard the Company’s ability to continue as a going concern in order to provide expected returns for partners and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital.

The Company manages its capital structure and makes adjustments to meet the changing economic market conditions. The Company's policy is to fund all projects of short and long term with their own operating resources. To maintain or adjust the capital structure, the Company may change the policy of paying dividends to shareholders, return capital to shareholders or issue new shares. No formal dividend policy exists. The financial position of the Company is as follows:

	2021	2020
	US$(000)	US$(000)
Debt and accounts payable	198,442	226,333
Leases	115	330
Less: cash and short-term deposits	(692,849)	(870,929)
Net debt	(494,292)	(644,266)
Total liquidity	692,849	870,929

(e) Fair value measurement -

Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).

As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assets that are measured at fair value on a recurring basis (at least annually) correspond to the San José Reservoir Trust assets and the accounts receivable from the sales of copper and silver concentrate subject to provisional pricing.

The Company’s San José Reservoir Trust assets are made up of marketable equity and debt securities that are valued using quoted market prices in active markets and as such are classified within Level 1 of the fair value hierarchy. The fair value of the marketable equity securities is calculated as the quoted market price of the marketable equity security multiplied by the quantity of shares held by the Company.

There were no transfers between Level 1and Level 2 during 2021, 2020 and 2019.

The Company’s impairment model uses valuation techniques to determine the WACC. These valuation techniques maximize the use of observable market data where it is available and rely as little as possible on entity specific estimates as such is classified within Level 2 of the fair value hierarchy.

Carrying value versus fair value

Set out below is a comparison of the carrying amount and fair value of the Company’s financial instruments, other than those which carrying amounts are reasonable approximation of fair value:

	Carrying amount		Fair value
	2021	2020	2021	2020
	US$(000)	US$(000)	US$(000)	US$(000)
Financial assets:
Trade and other receivables, net	37,105	27,658	37,105	27,658
Restricted cash	48,752	48,752	48,752	49,042
Financial assets at fair value	81	21,676	81	21,676
	85,938	98,086	85,938	98,376

	Carrying amount		Fair value
	2021	2020	2021	2020
	US$(000)	US$(000)	US$(000)	US$(000)
Financial liabilities:
Trade and other payables	86,659	68,645	86,659	68,645
Debt instrument	47,080	45,423	47,080	47,479
	133,739	114,068	133,739	116,124

Management assessed that the fair values of cash and short-term deposits, trade receivables, trade payables and other current liabilities approximate their carrying amounts largely due to short-term maturities of these instruments. Trade receivables subject to provisional pricing are already carried at fair value.

27.   Summary of significant differences between accounting principles followed by the Company and U.S. Generally Accepted Accounting Principles (U.S. GAAP)

The Company's consolidated financial statements have been prepared in accordance with International Financial Reporting Standards which differs in certain respects from U.S. GAAP. The effects of these differences are reflected in note 28 and are principally related to the items discussed in the following paragraphs:

(a)Impairment -

Under IFRS, the Company estimates the recoverable amount of an asset whenever there is an indication that the asset may be impaired. The recoverable amount is the higher of (i) the fair value less costs of disposal and (ii) its value in use. Value in use is the present value of the future cash flows expected to be derived from an asset or cash-generating unit. Impairment loss previously recorded is reversible in subsequent periods under certain conditions.

Under IFRS, the Company recorded in 2013 and 2016 an impairment loss related to its Conga and Yanacocha CGU for US$1,126,543 and US$1,342,645, respectively. In 2021, the Company recognized a reduction of the impairment loss for US$395,434 as a consequence of the classification of the certain assets of the Conga CGU as assets held for sale, see note 10. In 2020, and 2019, the Company did not recognize any impairment losses in relation to this CGU. In December 2021, the Company recorded a reversal of impairment for US$97,592 related to its Yanacocha CGU, see note 11.

Under U.S. GAAP, the Company uses undiscounted cash flows to perform its impairment assessment. In 2021 no impairment indicators were identified for Conga CGU.

F-175

Notes to the consolidated financial statements (continued)

In December 2020, the Company performed a formal evaluation of its cash generating units and concluded that there are indicators of reversal of impairment of its Yanacocha CGU and impairment indicators in its Conga CGU, therefore it determined the recoverable value of both CGUs. As a result of this analysis the Company concluded that no reversals of impairment loss on either of its’ CGU as the recoverable amount was slightly higher to the carrying amount of the CGU’s assets; however, due to de sensitive of the cash flows to the discount rate, long term prices and the term of the cash flows, the Management concluded that there is not appropriate recognized a reversal for the CGUs.

In 2019 no impairment indicators were identified for its Yanacocha and Conga CGU.

In 2016, the Company recorded an impairment loss related to its Yanacocha CGU for US$933,200.

For reconciling the net income/loss and net equity from U.S. GAAP to IFRS, the Company eliminates the higher depreciation recorded under U.S. GAAP corresponding to the impaired assets under IFRS.

(b)Stripping activity asset -

Under IFRS, the stripping costs in the production phase of a surface mine are accounted according to the accounting principles disclosed in note 2, consequently the stripping activity asset is capitalized as stripping activity asset and has an impact in the depreciation expense.

Under U.S. GAAP, the costs of clearing removal (stripping cost of production) incurred during the production stage are recorded as part of the production cost of inventories, accordingly, such costs are recorded on the consolidated income statement at an earlier time than IFRS.

(c)Reclamation and mine closure –

Under IFRS, the liability is measured in accordance with IAS 37 and IFRIC 1. Upward and downward revisions in the amount of undiscounted estimated cash flows are discounted using the current market-based discount rate (this includes changes in the time value of money and the risks specific to the liability), see note 2.4(l).

Under IFRS, the Company updates the discount rate used to discount its liability at the closing date using a risk-free rate, this change in the discount rate has an impact (increase/decrease) in the asset retirement cost and reclamation liability Under U.S. GAAP, upward revisions in the amount of undiscounted estimated cash flows are discounted using the current Company’s credit rate. Downward revisions in the amount of undiscounted estimated cash flows are discounted using the Company's credit rate that existed when the original liability was recognized. Under U.S. GAAP, there are no requirements of update the discount rate.

(d)Inventories -

Under IFRS, the cost of inventory mainly includes a lower depreciation as a result of the reduced value of property, plant and equipment due to the impairments recorded in prior years, the impact of the stripping activity asset and workers' profit sharing.

Under U.S. GAAP, the cost of inventory is affected by a different depreciation since the impairment recognized under U.S. GAAP is different than the one recognized under IFRS. According to U.S. GAAP, the workers' profit sharing is excluded in the the inventory costing.

(e)Contingencies -

Under IFRS, a provision is recognized when:

•An entity has a present obligation (legal or constructive) as a result of a past event.

•It is probable that an outflow of resources will be required to settle the obligation.

•A reliable estimate of the obligation can be made.

F-176

Notes to the consolidated financial statements (continued)

For the purposes of IAS 37, “probable” is defined as more likely than not and refers to a probability of greater than 50%.

Under U.S. GAAP, a loss contingency is recognized if both of the following conditions are met: It is probable (likely to occur) that an asset has been impaired or a liability has been incurred. The amount of loss can be reasonably estimated. The meaning of “probable” under ASC 450 is “the future event or events are likely to occur” (generally interpreted as between 70%-80%).

(f)Debt instruments -

Under IFRS, the shares held by Sumitomo (see note 13) meet the definition of a compound instrument according to IAS 32. As a result, it is classified as a liability (with a portion recorded to equity) until the option expires, in which case it will be required to be classified it as equity. There is no gain or loss on conversion at maturity. In the case the option is executed, both the liability and the equity would be reversed with a credit to cash.

Under U.S. GAAP, the shares held by Sumitomo are classified as temporary equity – contingently redeemable non-controlling interest (CRNCI) according ASC 480-10-S99-3A; as a long as the option is not expired, or it is exercised the CRNCI is recorded at fair value of inception which was determined to be equal to the purchase price.

(g)Subsequent events -

Under IFRS, the settlement after the reporting period of a court case that confirms that the entity had a present obligation at the end of the reporting period is an adjusting event after the reporting period.

During 2019, under IFRS the Company recognized a liability in tax payable, interest and fines for US$29 million related to a court case in accordance with IAS 37 Provisions, Contingent Liabilities and Contingent Assets, including the amount of the income tax to pay and the additional penalties and interests. See Note 24.

Under U.S. GAAP, a change in facts after the reporting date but before the financial statements are issued or are available in relation to a tax position which is effectively settled through litigation shall be recognized in the period in which the change in facts occurs, therefore the Company recognized the tax claim in the first quarter of 2020.

(h)Deferred income tax -

The differences between U.S. GAAP and IFRS are re-measurements that lead to different temporary differences and accordingly, the Company accounts for the effect on the deferred income tax related to such differences.

As the Company does not recognize deferred income tax assets based on its recoverability analysis, there is no differences to reconcile.

(i)Deferred workers’ profit sharing -

Under IFRS, the worker’s profit sharing is calculated based on the Company’s taxable income and is recorded as an employee benefit (cost of production or administrative expenses, depending on the function of the workers).

Under U.S. GAAP, the workers’ profit sharing is treated in a similar way as income tax since both are calculated based on the Company’s taxable income. Therefore, the Company calculates a deferred workers’ profit sharing resulting from the taxable and deductible and deductible temporary differences.

As the Company does not recognize deferred workers’ profit sharing assets based on its recoverability analysis in U.S. GAAP, there is no differences to reconcile.

28.    New U.S. GAAP Accounting Pronouncements

Accounting for Income Tax

In December 2019, Accounting Standard Update ("ASU") No. 2019-12 was issued to simplify the accounting for income taxes, eliminate certain exceptions within Accounting Standard Codification (“ASC”) 740, Income Taxes, and clarify certain aspects of the current guidance to promote consistency among reporting entities.

The Company adopted this standard as of January 1, 2021. The adoption did not have a material impact on the Consolidated Financial Statements or disclosures.

Effects of Reference Rate Reform

In March 2020, ASU No. 2020-04 was issued which provides optional guidance for a limited period of time to ease the potential burden on accounting for contract modifications caused by reference rate reform. In January 2021, ASU No. 2021-01 was issued which broadened the scope of ASU No. 2020-04 to include certain derivative instruments. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. The guidance may be adopted over time as reference rate reform activities occur and should be applied on a prospective basis.

The Company does not expect this ASU to have an impact on its accounting or consolidated financial statements.

29.   Subsequent Event

The Company continues to monitor the evolution of the pandemic situation and the guidance of national and international authorities, as events beyond the control of Management may arise that require adjustment of the business plan. A new outbreak or further spread of COVID-19 and the consequent steps taken to limit the spread of the disease could affect the Company's ability to conduct business in the usual way and therefore affect the financial condition and operating result of the Company.

In February 2022, Newmont completed the acquisition of Buenaventura’s 43.65% noncontrolling interest in Yanacocha. Refer to note 1 for further details regarding this Transaction.

In March 2022, Sumitomo exercised its option to require Yanacocha to repurchase its 5% interest, which is expected to close in the second quarter of 2022. Upon close, Yanacocha will repay the US$48 in exchange for the 5% ownership interest held by Sumitomo and the Company will hold 100% ownership interest in Yanacocha. Refer to note 15 for further information..

Report of Independent Auditors

To the Shareholders and the Board of Directors of Sociedad Minera Cerro Verde S.A.A.

Opinion on the Financial Statements

We have audited the accompanying statement of financial position of Sociedad Minera Cerro Verde S.A.A., (the Company) as of December 31, 2021 and 2020, and the related statements of comprehensive income, changes in shareholders’ equity and cash flows for each of the three years in the period ended December 31, 2021, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board, which differ in certain respects from the accounting principles generally accepted in the United States of America (see notes 23 and 24 to the financial statements).

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Notes to the Financial Statements

As of December 31, 2020, 2019 and 2018

1.     Identification and business activity

(a) Identification -

Sociedad Minera Cerro Verde S.A.A. (the Company) was incorporated in Peru on August 20, 1993, as a result of the privatization process of certain mining units carried out by the Peruvian State in that year. The Company’s shares began being listed on the Lima Stock Exchange on November 14, 2000.

Through its subsidiary Cyprus Climax Metals Company, Freeport Minerals Corporation (FMC), a wholly owned subsidiary of Freeport-McMoRan Inc. (Freeport), owns 53.56% of the voting shares of the Company, SMM Cerro Verde Netherlands B.V. (SMM Cerro Verde), a subsidiary of Sumitomo Metal Mining Company Ltd. (Sumitomo), owns 21.00%, Compañía de Minas Buenaventura S.A.A. (Buenaventura) owns 19.58%, and other stakeholders own the remaining 5.86%.

The Company’s legal address is Jacinto Ibañez Street N°315 - Parque Industrial, Arequipa in the city of Arequipa and the ore deposit is located 20 miles southwest of that city (Asiento Minero Cerro Verde S/N Uchumayo – Arequipa).

(b) Business activity -

The Company’s activities are regulated by the Peruvian General Mining Law and comprise the extraction, production and sale of copper cathodes, copper concentrate and molybdenum concentrate.

Cerro Verde’s operation consists of an open-pit copper mine, with a processing capacity of 548,500 metric ton-per-day that includes (i) concentrator facilities with a 409,500 metric ton-per-day permitted capacity (361,500 metric ton-per-day before the expansion approved by the Ministry of Energy and Mines during 2018), (ii) solution extraction and electrowinning (SX/EW) leaching facilities with leach copper production derived from a 39,000 metric ton-per-day crushed leach facility and (iii) a run-of-mine (ROM) leach system with a capacity of 100,000 metric ton-per-day. This SX/EW leaching operation has a production capacity of approximately 200 million pounds of copper per year. The leaching and flotation process carried out at these plants are part of the benefit concession “Planta de Beneficio Cerro Verde.”

(c) COVID-19 outbreak in Peru -

On March 15, 2020, the Peruvian government issued a Supreme Decree and declaration of a National Emergency in its efforts to contain the outbreak of COVID-19. The order was initially for fifteen days but was subsequently extended for different periods through March 31, 2022.

During the year 2021, Cerro Verde milling rates at concentrator plants averaged 380,300 metric tons per day. Subject to ongoing monitoring of COVID-19 protocols, Cerro Verde is targeting milling rates to increase to approximately 400,000 metric tons of ore per day during 2022 . During 2020, Cerro Verde temporarily went into a state of care and maintenance and adjusted its operations to prioritize critical activities , in order to comply with government requirements. As a result, the Company revised its operating plans (milling rates at concentrator plants averaged 331,600 metric tons per day). A summary of the impacts and charges associated with COVID-19 are detailed in Note 15(b).

Cerro Verde continues to update its Plan for the Surveillance, Prevention and Control of COVID-19 at work. The implementation of these prevention, early detection and response measures and actions helps to control the risk of spread and health impacts caused by the COVID-19 pandemic during the development of operational activities.

(d) Financial statements approval –

The financial statements for the year ended December 31, 2021 were approved by Company’s Management on May 13, 2022 and the subsequent events have been considered through those dates.

The financial statements for the year ended December 31, 2020, were approved at the Board of Directors’ Meetings on April 29, 2021.

2.     Significant accounting principles and policies

The significant accounting policies applied in the preparation of the financial statements are summarized below:

(a)Basis of presentation -

The financial statements of the Company have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

The financial statements have been prepared based on historical cost, except for accounts receivable and/or payable related to embedded derivatives, which have been measured at fair value (see Note 2(d)). The financial statements are presented in United States dollars (US$). Unless otherwise indicated, all values have been rounded to the nearest thousand.

(b)Use of judgments, estimates and assumptions -

The preparation of financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions in order to determine the amounts of the assets and liabilities, and the disclosure of contingent assets and liabilities as of December 31, 2021 and 2020, and the amounts of reported revenues and expenses for the years ended December 31, 2021, 2020 and 2019.

Information about significant judgments, estimates and assumptions made by Management in the preparation of the financial statements follows:

(b.1)       Judgments -

(i)   Contingencies -

By their nature, contingencies will be resolved only when one or more uncertain future events occur or fail to occur. The assessment of the existence and potential amount of contingencies inherently involves the exercise of significant judgment and the use of estimates regarding the outcome of future events.

(ii)   Stripping cost -

The Company incurs waste removal costs (stripping costs) during the development and production phases of its surface mining operations. Production stripping costs can be incurred both in relation to the production of inventory in that period and the creation of improved access and mining flexibility in relation to ore to be mined in the future. The waste removal cost is included as part of the costs of inventory, while the production stripping costs are capitalized as a stripping activity asset, as part of the “property, plant and equipment, net” caption, if certain criteria are met.

Once the Company has identified its production stripping for its surface mining operation, it identifies the separate components of the ore body. An identifiable component is a specific volume of the ore body that is made more accessible by the stripping activity. Significant judgment is required to identify and define these components, and to determine the expected volumes (e.g., in tons) of waste to be stripped and ore to be mined in each of these components.

F-189

Notes to the Financial Statements (continue)

(b.2)       Estimates and assumptions -

(i)   Determination of mineral reserves -

Mineral reserves are the part of a mineral deposit that can be economically and legally extracted from the mine concessions. The Company estimates its mineral reserves based on information compiled by individuals qualified in reference to geological data about the size, depth and form of the ore body, and requires geological judgments in order to interpret the data.

The estimation of recoverable mineral reserves involves numerous uncertainties with respect to the ultimate geology of the ore body, including quantities, grades and recoveries. Estimating the quantity and grade of mineral reserves requires the Company to determine the size, shape and depth of the ore body by analyzing geological data. In addition to the geology, assumptions are required to determine the economic feasibility of mining the mineral reserves, including estimates of future commodity prices and demand, future requirements of capital and production costs, and estimated exchange rates. Revisions in mineral reserve or mineral resource estimates have an impact on the value of mining properties, its related property, plant and equipment, provisions for cost of mine closure, recognition of assets for deferred taxes and depreciation and amortization of assets.

(ii)  Units of production depreciation -

Estimated mineral reserves are used in determining the depreciation and/or amortization of mine-specific assets. This results in a depreciation/amortization charge proportional to the depletion of the anticipated remaining life-of-mine production. The life of each item, which is assessed at least annually, is impacted by both its physical life limitations and present assessments of economically recoverable mineral reserves of the mine property at which the asset is located. These calculations require the use of estimates and assumptions, including the amount of recoverable mineral reserves.

(iii) Provision for remediation and mine closure -

The Company assesses its provision for remediation and mine closure quarterly. It is necessary to make estimates and assumptions in determining this provision, including cost estimates of activities that are necessary for the rehabilitation of the site, technological and regulatory changes, interest rates and inflation rates. As discussed in Note 2(k), estimated changes in the fair value of the provision for remediation and mine closure or the useful life of the related assets are recognized as an increase or decrease in the book value of the provision and related asset retirement cost (ARC) in accordance with IAS 16, “Property, Plant and Equipment.”

According to the Company’s accounting policies, the provision for remediation and mine closure represents the present value of the costs that are expected to be incurred in the closure period of the operating activities of the Company. Closure budgets are reviewed regularly to take into account any significant change in the studies conducted. Nevertheless, the closure costs of mining units will depend on the market prices for the closure work required, which would reflect future economic conditions. Also, the timing of disbursements depends on the useful life of the mine, which are based on estimates of future commodity prices.

If any change in the estimate results in an increase to the provision for remediation and mine closure and related ARC, the Company considers whether or not this is an indicator of impairment of the assets and applies impairment tests in accordance with IAS 36, “Impairments of Assets.”

(iv) Inventories -

Net realizable value (NRV) tests are performed at least annually and represent the estimated future sales price of the product based on prevailing spot metal prices, less estimated costs to complete production and bring the inventory to sale. Additionally, in calculating the NRV of the Company’s long-term stockpiles, Management also considers the time value of money.

F-190

Notes to the Financial Statements (continue)

Mill and leach stockpiles generally contain lower grade ores that have been extracted from the ore body and are available for copper recovery. Mill stockpiles contain sulfide ores and recovery of metal is through milling and concentrating. Leach stockpiles contain oxide ores and certain secondary sulfide ores and recovery of metal is through exposure to acidic solutions that dissolve contained copper and deliver it in solution to extraction processing facilities.

Because it is generally impracticable to determine copper contained in mill and leach stockpiles by physical count, reasonable estimation methods are employed. The quantity of material delivered to mill and leach stockpiles is based on surveyed volumes of mined material and daily production records. Sampling and assaying of blast hole cuttings determine the estimated copper grades of material delivered to mill and leach stockpiles.

Expected copper recovery rates for mill stockpiles are determined by metallurgical testing. The recoverable copper in mill stockpiles, once entered into the production process, can be produced into copper concentrate almost immediately.

Expected copper recovery rates for leach stockpiles are determined using small-scale laboratory tests, historical trends and other factors, including mineralogy of the ore and rock type. Total copper recovery in leach stockpiles can vary significantly depending on several variables, including processing methodology, processing variables, mineralogy and particle size of the rock. For newly placed material of active stockpiles, as much as 80 percent of the total copper recovery may occur during the first year, and the remaining copper may be recovered over many years. Process rates and metal recoveries are monitored regularly, and recovery estimates are adjusted periodically as additional information becomes available and as related technology changes.

(v)   Asset impairment -

Management has determined that the Company’s operations consist of one cash generating unit. The Company’s operations are evaluated at least annually in order to determine if there are impairment indicators. If any such indication exists, the Company makes an estimate of the recoverable amount, which is the higher of (i) the fair value less costs of disposal or (ii) the value in use. These assessments require the use of estimates and assumptions, including long-term commodity prices, discount rates, operating costs and other factors.

Fair value is defined as the amount that would be obtained from the sale of the asset in an arm’s length transaction between willing and knowledgeable parties. The fair value of assets is generally determined as the current value of future cash flows derived from the continuous use of the asset, which includes estimates, such as the cost of future expansion plans and eventual disposal, while applying assumptions that an independent market participant may take into account. The cash flows are discounted by applying a discount rate that reflects the current market, the time value of money and the risks specific to the asset.

(c)   Functional and reporting currency  -

The financial statements are presented in United States (US) dollars, which is also the Company’s functional currency.

Transactions and balances in foreign currency

Foreign currency transactions are those carried out in a currency other than the functional currency. Foreign currency transactions are translated into the functional currency by applying the exchange rate in force on the date the transaction takes place. Monetary assets and liabilities denominated in foreign currencies are converted using the functional currency spot rate in force at the reporting date.

Gains and losses as a result of the difference in the exchange rate when currency items are liquidated or when converting currency items at exchange rates that are different from those used for their initial recognition are recognized in the statements of comprehensive income of the period.

F-191

Notes to the Financial Statements (continue)

The Company uses Peruvian Sol (S/) exchange rates published by the Superintendent of Banks, Insurance and Pension Fund Administrators. The published exchange rates were S/3.975 for US$1 for buying and S/3.998 for US$1 for selling as of December 31, 2021, and S/3.618 for US$1 buying and S/3.624 for US$1 for selling as of December 31, 2020. These rates have been applied to the appropriate asset and liability accounts.

(d)   Financial assets –

Initial recognition and measurement -

At initial recognition, financial assets are classified and measured at either amortized cost, or fair value through profit or loss.

The classification of financial assets at initial recognition depends on the financial asset’s contractual cash flow characteristics and the Company´s business model for managing them. With the exception of trade receivables that do not contain a significant financing component, the Company initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Trade receivables that do not contain a significant financing component are measured at the transaction price determined under IFRS 15, “Revenue from Contracts with Costumers.”

The Company’s business model for managing financial assets refers to how it manages its financial assets in order to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets or both.

Purchases or sales of financial assets that require delivery of assets within a time frame established by regulation or convention in the marketplace (regular way trades) are recognized on the trade date.

Cash and cash equivalents -

Cash and cash equivalents are financial assets that may be liquidated immediately, such as bank checking accounts, and other liquid investments with original maturities of three months or less.

Accounts Receivables -

The Company’s receivables include current and non-current trade and other accounts receivable. These receivables are stated at their transaction value, net of an allowance for expected credit loss. Trade accounts receivable are generated primarily from the Company’s concentrate and cathode sales, are denominated in US dollars, have current maturities, do not bear interest and have no specific guarantees.

Receivables are non-derivative financial assets with fixed or determinable payments that are not quoted in an active market.

Subsequent measurement -

For purposes of subsequent measurement, financial assets are classified in two categories:

-      Financial assets at amortized cost (debt instruments).

-      Financial assets at fair value through profit or loss.

Financial assets at amortized cost (debt instruments) -

This category is the most relevant to the Company. The Company measures financial assets at amortized cost if both of the following conditions are met:

-      The financial asset is held within a business model with the objective to collect contractual cash flows, and

-      The contractual terms of the financial asset give rise, on specified dates, to cash flows that are solely payments of principal and interest on the principal amount outstanding.

Financial assets at amortized cost are subsequently measured using the effective interest rate method and are subject to impairment. Gains and losses are recognized in the statements of comprehensive income when the asset is derecognized, modified or impaired.

F-192

Notes to the Financial Statements (continue)

This category generally applies to trade and other receivables, net.

Financial assets at fair value through profit or loss -

Financial assets at fair value through profit or loss include financial assets held for trading, financial assets designated upon initial recognition at fair value through profit or loss or financial assets mandatorily required to be measured at fair value. Financial assets are classified as held for trading if they are acquired for the purpose of selling or repurchasing in the near term. Derivatives, including separated embedded derivatives, are also classified as held for trading unless they are designated as effective hedging instruments. Financial assets with cash flows that are not solely payments of principal and interest are classified and measured at fair value through profit or loss, irrespective of the business model.

Financial assets at fair value through profit or loss are carried in the statements of financial position at fair value with net changes in fair value recognized in the statements of comprehensive income.

Embedded derivatives -

Copper Sales -

The Company’s copper sales are provisionally priced at the time of shipment. The provisional prices are finalized in a specified future month based on quoted London Metal Exchange (LME) monthly average prices. The Company receives market prices based on prices in the specified future month, which results in price fluctuations recorded through revenues until the date of settlement. The Company recognizes revenues and invoices customers when it transfers control, which is under CIF (cost, insurance and freight) delivery point based on then-current LME prices, which results in an embedded derivative that is required to be separated from the main contract. The Company’s embedded derivatives from sales are measured at fair value (based on LME spot copper prices) and presented as gains/losses on provisionally priced trade receivables (see Note 21).

Molybdenum Sales -

The Company’s molybdenum sales are also provisionally priced at the time of shipment. The Company recognizes revenues and invoices customers when it transfers control, which is under the CIF delivery point based on the arithmetic mean of the high and low Metals Week Dealer Oxide (MWDO) price. The provisional prices are finalized in a future month, according to the period of quotation, which results in price fluctuations recorded through revenues until the date of settlement, which also results in an embedded derivative that is required to be separated from the main contract (see Note 21).

Derecognition -

A financial asset (or, where applicable a part of a financial asset or part of a group of similar financial assets) is primarily derecognized when:

-      The rights to receive cash flows from the asset have expired; or

-      The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a pass-through arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset or, (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered into a pass-through arrangement, it evaluates if and to what extent, it has retained the risk and rewards of ownership. When it has neither transferred nor retained substantially all of the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of the Company´s continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Impairment of financial assets -

The Company recognizes an allowance for expected credit losses for all debt instruments not held at fair value through the statements of comprehensive income. Expected credit losses are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at an

F-193

Notes to the Financial Statements (continue)

approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms.

Expected credit losses are recognized in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, expected credit losses are provided for credit losses that result from default events that are possible within the next 12-months (12-month expected credit losses). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (lifetime expected credit losses).

For trade receivables and contract assets, the Company applies a simplified approach in calculating expected credit losses. Therefore, the Company does not track changes in credit risk, but instead recognizes a loss allowance based on the financial asset’s lifetime expected credit losses at each reporting date.

The Company considers a financial asset in default when contractual payments are 180 days past due. However, in certain cases, the Company may also consider a financial asset to be in default when internal or external information indicates that the Company is unlikely to receive the outstanding contractual amounts in full before taking into account any credit enhancements held by the Company. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.

(e)   Financial liabilities -

All financial liabilities are recognized initially at fair value and in the case of accounts payable and other financial liabilities, net of directly attributable transaction costs. The Company´s financial liabilities include loans, trade and other payables and other financial liabilities.

Loans -

Loans are initially recognized at their fair value, net of directly attributable transaction costs. After initial recognition, loans are subsequently measured at amortized cost using the effective interest rate method. Gains and losses are recognized in the statements of comprehensive income when the liabilities are derecognized as well as through the amortization process.

Amortized cost is calculated taking into account any discount or premium on acquisition and fees or costs that are an integral part of the effective interest rate. Amortization under the effective interest rate method is included as financial costs in the statements of comprehensive income.

Derecognition -

A financial liability is derecognized when the associated obligation is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts are recognized in the statements of comprehensive income.

(f)   Inventories -

Inventories are stated at the lower of cost or net realizable value. Inventory of materials and supplies, as well as saleable products and in-process inventory are determined using the weighted-average cost method. The cost of finished goods and in-process inventory (i.e., stockpiles) includes labor and benefits, supplies, energy and other costs related to the mining and processing of minerals. Net realizable value tests of saleable products and in-process inventory are performed at each reporting date and represent the estimated future sales price using forward metal prices (for the period they are expected to be processed in), less estimated costs to complete production and bring the inventory to sale. The current portion of work-in-process is determined based on the amount the Company expects to process in the next 12 months. Inventories that are not expected to be processed in the next 12 months are classified as non-current inventories.

No adjustments to inventories were required as of December 31,2021 and 2020.

F-194

Notes to the Financial Statements (continue)

(g)   Property, plant and equipment -

Property, plant and equipment are valued at historical cost, including costs that are directly attributed to the construction or acquisition of the asset, net of accumulated depreciation, amortization and impairment.

The initial cost of an asset comprises its purchase price or construction cost, any costs directly attributable to bringing the asset into operation, the initial estimate of the obligation for mine closure, and borrowing costs for qualifying assets.

Repairs and/or improvements that increase the economic life of an asset and for which it is probable that there will be future economic benefit to the Company, are recorded as assets. All other maintenance costs are charged to expense as incurred.

Land is not depreciated. Depreciation of assets directly related to the useful life of the mine is calculated using the units-of-production (UOP) method based on the mine’s proven and probable copper reserves. Other assets are depreciated using the straight-line method based on the following estimated useful lives:

	Years
Buildings and other constructions	Between 5 and 35
Machinery and equipment	Between 2 and 30
Transportation units	Between 5 and 7
Furniture and fixtures	Between 7 and 10
Other equipment	Between 3 and 25

Critical spare parts and other parts which are directly identified with machinery or equipment are included in property, plant and equipment, and the economic life corresponds to the main asset with which they are identified.

An asset within property, plant and equipment is retired at the time of its disposal or when no future economic benefits are expected from its use or subsequent disposition. Any gain or loss arising at the time of retirement is calculated as the difference between the proceeds from the sale and the book value of the asset and is included in the statements of comprehensive income in the period the asset is retired.

The residual value and economic useful lives of the Company’s property, plant and equipment are reviewed, and adjusted if appropriate, at each year end.

Impairment -

At each reporting date, the Company evaluates if there is any indication that an asset could be impaired. If such an indication exists, the Company estimates the recoverable amount of the asset. The recoverable amount of an asset is the greater of (i) its fair value less costs to sell or (ii) its value in use and is determined for the assets of the mine as a whole, since there are no assets that generate cash revenues independently.

When the book value of an asset exceeds its recoverable amount, the asset is considered impaired and is reduced to its recoverable amount. When evaluating the value in use, the future estimated cash flows are discounted to their present value using an after-tax discount rate that reflects current market evaluations of the time value of money and the specific risks to the asset.

Losses resulting from the impairment of assets are recognized in the statements of comprehensive income under the categories of expenses consistent with the function of the impaired asset. A previously recognized impairment loss is reversed only if there has been a change in the estimates used to determine the asset’s recoverable amount since the last impairment loss was recognized. The revised valuation cannot exceed the book value that would have been determined, net of depreciation, if an impairment loss for the asset had not been recognized in a previous period. Such a reversal is recognized in the statements of comprehensive income.

The Company did not identify any indicators of impairment for the years ended December 31, 2021 and 2020.

F-195

Notes to the Financial Statements (continue)

(h)   Leases -

The Company assesses all arrangements, at contract inception, to determine whether they are, or contain, a lease. A contract containing a lease conveys the right to control the use of an identified asset for a period of time in exchange for consideration. The Company is a lessee but is not a lessor in any transactions.

The Company applies a single recognition and measurement approach for all leases, except for short-term leases and low-value assets. The Company recognizes lease liabilities representing obligations to make future lease payments and right-of-use assets representing the right to use the underlying assets.

(i)   Right-of-use assets -

The Company recognizes a right-of-use asset at the commencement date of the lease (i.e., the date when the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any re-measurement of lease liabilities. Right-of-use assets are depreciated on a straight-line basis over the shorter of the lease term or the estimated useful lives of the assets, as follows:

	Years
Land	30
Buildings and other constructions	Between 1 and 14
Machinery and equipment	Between 3 and 14

The right-of-use assets are also subject to impairment. The Company did not identify any indicators of impairment as of December 31, 2021 and 2020.

(ii)   Lease liabilities -

At the commencement date of the lease, the Company recognizes a lease liability measured at the present value of lease payments to be made over the lease term. The lease liability is re-measured when there is a change in future lease payments arising from a change in an index or a rate, if there is a change in the estimate of the amount expected to be payable under a residual value guarantee, or as appropriate, changes in the assessment of whether a purchase option, termination option or extension option is reasonably certain to be exercised. Variable lease payments that do not depend on an index or a rate are recognized as expenses in the period in which the event or condition that triggers the payment occurs.

In calculating the present value of lease payments, the Company uses its incremental borrowing rate at the lease commencement date because the interest rate implicit in the lease is generally not readily determinable. After the commencement date, lease liabilities are increased to reflect the accretion of interest and reduced for the lease payments made. A summary of lease liabilities aging is described in Note 20(d).

(i)   Intangible assets -

Intangible assets are recorded at cost less accumulated amortization. After the initial recognition, the intangible assets are recorded at their cost less accumulated amortization and any accumulated loss for impairment of use, if applicable.

The Company’s intangible assets primarily consist of concessions related to the operation of the port terminal, which are amortized over 20 years using the straight-line method. Amortization expense was US$ 1.5 million for the year ended December 31, 2021, and US$ 1.0 million for each of the years ended December 31, 2020 and 2019 and is presented within the "Depreciation and amortization” in cost of sales (see Note 15).

The gross book value for intangible assets was US$ 20.0 million at December 31, 2021, and US$ 13.1 million as of December 31, 2020, and accumulated amortization was US$ 6.2 million as of December 31, 2021, and US$ 4.7 million as of December 31, 2020.

F-196

Notes to the Financial Statements (continue)

(j)   Exploration, development and stripping costs -

Exploration costs -

Mineral exploration costs, as well as drilling and other costs incurred for the purpose of converting mineral resources to proven and probable reserves or identifying new mineral resources at development or production stage properties, are charged to the statements of comprehensive income as incurred.

Development costs -

Development costs are capitalized when the economic and technological feasibility of the project is confirmed, which is generally when the development or project has reached a milestone in accordance with a model established by management.

Stripping cost -

The stripping costs incurred in the production phase are capitalized as a component of property, plant and equipment, net (see Note 2 (b.1) and 7) if the stripping activity improves access to the ore body or enhances an existing asset. The stripping activity asset is initially measured at cost, which is the accumulation of costs directly incurred to perform the stripping activity. The stripping activity asset is subsequently amortized using the UOP method over the component of the ore body benefitted.

(k)    Provisions -

General -

A provision is recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that resources of the Company will be required to settle the obligation, and an estimate of the amount of the obligation can be calculated. The expense relating to any provision is presented in the statements of comprehensive income, net of any reimbursement, in the period the provision is established.

If the effect of the time value of money is significant, provisions are discounted by applying a discount rate that reflects, where applicable, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as a financial expense in the statements of comprehensive income.

Mine closure provision -

The Company records a mine closure provision when a contractually or legally enforceable obligation arises. The Company estimates the present value of its future obligation for mine closure and increases the carrying amount of the related ARC, which is included in property, plant and equipment, net in the statements of financial position. Subsequently, the mine closure provision is accreted to full value over time. The related ARC is depreciated using the UOP method over the life of the mine.

The Company evaluates its mine closure provision on a quarterly basis and makes adjustments to estimates and assumptions, including scope, future costs and discount rates, as applicable. Changes in the fair value of the mine closure provision or the useful life of the related asset are recognized as an increase or decrease in the book value of the provision and the related ARC. Any decrease in the mine closure provision and related ARC cannot exceed the current book value of the asset; amounts over the current book value are recorded in the statements of comprehensive income.

(l)   Revenue recognition -

The Company primarily sells copper concentrate and copper cathode in accordance with sales contracts entered into with its customers. Revenues from contracts with customers comprise the fair value of the sale of goods, net of related general sales taxes. Revenue from contracts with customers is recognized when control of goods or services are transferred to the customer at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods.

The Company has concluded that it acts as the principal in its revenue contracts because it normally controls the goods before transferring them to its customers.

The transfer of control is determined in accordance with the terms of each of the contracts entered into with the Company's customers; generally, under such contracts, the transfer of control occurs at the time of shipment or delivery of the goods, including transportation.

F-197

Notes to the Financial Statements (continue)

The Company considers whether there are other promises in the contract that are separate performance obligations to which a portion of the transaction price needs to be allocated. The Company consider that the only performance obligation is the delivery of the goods. In determining the transaction price for the sale of copper concentrates and copper cathode, the Company considers the effect of variable consideration and the existence of significant financing components.

Revenues from the sale of copper concentrates and cathodes are recorded net of commercial deductions. Commercial deductions include price adjustments for treatment and refining charges and may include certain penalties that, according to the applicable contract, are deducted from the international spot price, and that are incurred after the time of sale of the applicable concentrate. The Company considers these deductions as part of the transaction price. The normal credit term is within 30 days after the fulfillment of the terms of the contract.

Variable consideration -

If the consideration in the contract includes a variable amount, the Company estimates the amount of consideration to which it will be entitled in exchange for transferring the goods to the customer. The variable consideration is estimated at contract inception and constrained until it is highly probable that a significant revenue reversal in the amount of cumulative revenue recognized will not occur when the associated uncertainty with the variable consideration is subsequently resolved.

The Company's sales of copper concentrates and cathodes allow for price adjustments based on the market price at the end of the trading period stipulated in the contract. These are called provisional pricing agreements in which the selling price of the copper is settled in a contractually specified future month based on quoted monthly average copper settlement prices. Sales price adjustments occur based on movements in quoted market prices until the end of the trading period. The period between provisional billing and the end of the listing period can generally range from three to six months.

In addition, the Company's sales of copper concentrates and cathodes are also subject to variations in their amount that may occur while the goods are in transit to their destination as a result of variations in moisture, weight and mineral grades. These variations are recognized directly as part of “Revenues” once the Company reaches an agreement with the corresponding customer regarding the final amounts sold.

Sales of copper concentrates and cathodes at provisional prices include a gain (loss) to be received at the end of the trading period; this is considered a form of variable consideration. Changes in price during the listing period are recognized within “Revenues.”

For provisional pricing arrangements, any future changes to the QP (Quotation Period) are embedded within provisionally priced trade receivables and therefore are within the scope of IFRS 9, “Financial Instruments” and not within the scope of IFRS 15. Given the exposure to the price of raw materials, trade receivables with a provisional price will not pass the test of cash flow characteristics within IFRS 9 and will be required to be measured at fair value with changes in the statement of comprehensive income from the initial recognition and until the settlement date. Subsequent changes in fair value are recognized in the statement of comprehensive income for each period. Changes in fair value during and until the end of the trading period are estimated by reference to the updated forward market prices for copper, as well as taking into account other relevant fair value considerations established in IFRS 13, “Fair Value Measurement,” including adjustments for interest rate and credit risk.

Revenue is recognized at the amount the entity expects to be entitled. The estimated price that is expected to be received at the end of the quotation period is generally the shipping or delivery month price, according to the terms of the contracts and using the most recently determined estimate of metal in concentrate (based on initial assay results) and the estimated forward price.

The requirements in IFRS 15 on constraint estimates of variable consideration are also applied to determine the amount of variable consideration that can be included in the transaction price.

Notes to the Financial Statements (continue)

Significant financing components -

The Company receives short-term advances from its customers. Using the practical expedient in IFRS 15, the Company does not adjust the promised amount of consideration for the effects of a significant financing component if it expects, at contract inception, that the period between the transfer of the promised good to the customer and when customer pays for that good will be one year or less.

Contract balances -

Contract assets

A contract asset is the right to consideration in exchange for goods or services transferred to the customer. If the Company transfers goods or services to a customer before the customer pays for those goods or services or before payment is due, a contract asset is recognized for the earned consideration that is conditional. The Company does not have any contract assets as performance and a right to consideration occurs within a short period of time and all rights to consideration are unconditional.

Trade receivables

A receivable represents the Company’s right to an amount of consideration that is unconditional (i.e., only the passage of time is required before payment of the consideration is due). See Note 2(d) for accounting policies for financial assets.

Contract liabilities

A contract liability is the obligation to transfer goods or services to a customer for which the Company has received consideration (or an amount of consideration is due) from the customer. If a customer pays before the Company transfers goods or services to the customer, a contract liability is recognized when the payment is made, or the payment is due (whichever is earlier). Contract liabilities are recognized as revenue when the Company performs under the contract.

(m)  Income taxes, deferred taxes and other taxes -

Income taxes -

Income tax assets and liabilities are measured at the amounts expected to be paid to or recovered from the tax authorities. The amount of current tax payable or receivable is the best estimate of the tax amount to be paid or received that reflects uncertainty related to income taxes, if any. The tax rates and tax laws that are applied to compute the amounts are those that are enacted or substantially enacted at the end of the reporting period. The Company calculates the provision for income tax in accordance with the Peruvian tax legislation in force. For the years ended December 31, 2021, 2020 and 2019, the Company was subject to an income tax rate of 32% (see Note 13(b)).

Deferred Taxes -

Deferred taxes are presented using the liability method for differences between the tax basis of assets and liabilities and their book value for financial reporting purposes. Deferred tax liabilities are recognized for all taxable differences. Deferred tax assets are recorded for all deductible differences when there is a probability that there could be taxable earnings against which the deductible difference could be applied.

The book value of deferred tax assets is reviewed at the end of each period and reduced to an amount that is more likely than not to be realized against taxable earnings. Deferred tax assets that are not recognized are reassessed each period and are recognized when it is more likely than not that those future taxable earnings will allow the deferred tax asset to be recovered.

Deferred tax assets and liabilities are measured at tax rates that are expected to be applicable during the year when the assets are realized or the liabilities are liquidated, based on the tax rates (and tax laws) that have been enacted or substantively enacted at the end of the period, and reflects uncertainty related to income taxes, if any. Deferred tax assets and liabilities are offset if there is a legally enforceable right to offset tax assets against tax liabilities and the deferred tax is related to the same entity and the same tax authority.

Mining Taxes -

On September 29, 2011, Law 29788 (which amended Law 28528) was enacted creating a new mining tax and royalty regime in Peru. Under the new regime, companies are subject to the payment of royalties and a special mining tax. Under the terms

F-199

Notes to the Financial Statements (continue)

of its current 15-year stability agreement (see Note 13(a)), which became effective January 1, 2014, the Company is subject to mining royalties and a special mining tax for all of its mining production (see Note 13(d)).

The amount to be paid for mining royalties will be the greater of a progressive rate of quarterly operating income ranging from 1% to 12% that increase progressively for companies with higher operating margins or 1% of quarterly sales. Mining royalties calculated on sales are presented in “Other operating expenses.”

Mining royalties and special mining tax are accounted for in accordance with IAS 12, "Income Tax" because they have the characteristics of an income tax. This is considered to be the case when they are imposed under government authority and the amount payable is based on taxable income-rather than physical quantities produced or as a percentage of revenue after adjustment for temporary differences. Legal rules and rates used to calculate the amounts payable are those in effect on the date of the statement of financial position.

Therefore, obligations arising from mining royalties and special mining tax are recognized as income tax under the scope of IAS 12, "Income Tax." Both, mining royalties and special mining tax generate deferred tax assets and liabilities, which must be measured using the average rates expected to apply to operating income in the quarter in which the company expects to reverse temporary differences.

Supplementary Retirement Fund -

On July 9, 2011, Law 29741 was enacted and established a Mining, Metallurgical and Steel Supplementary Retirement Fund (SRF), which is a social security retirement fund for mining, metals and steel industry workers. Under the terms of its current 15-year stability agreement, the Company is subject to SRF, which is calculated as 0.5% of taxable income.

Uncertainty about the treatment of income taxes -

The Company determines whether it considers each uncertain tax treatment separately or in conjunction with one or more other uncertain tax treatments based on the approach that best predicts the resolution of the uncertainty.

The Company makes judgments and estimates when there is uncertainty regarding the income tax treatments (see Notes 6 and 11).

The Company has uncertain tax positions, particularly those related to tailing dams, sales commissions with non-related companies and small fixed asset acquisitions.

The Company determined, based on its tax compliance and transfer pricing study, that its tax treatments are likely to be accepted by the tax authorities (see Notes 6(b) and 11(d)).

(n)   Benefits to employees -

Salaries and wages, bonuses, severance and vacation benefits are calculated in accordance with IAS 19, "Employee Benefits" and current Peruvian legislation.

Worker’s profit sharing -

The Company recognizes worker’s profit sharing in accordance with IAS 19. Worker’s profit sharing is calculated in accordance with Peruvian laws (Legislative Decree No. 892), and the Company’s worker’s profit sharing rate is 8% over the net taxable base of the current year. According to Peruvian law, the limit in the worker’s profit sharing that an employee can receive is equivalent to 18 months of wages, and any excess above such limit is transferred to the Regional Government and the National Fund for Employment’s Promotion and Training (FONDOEMPLEO). The Company’s worker’s profit share is recognized as a liability in the statements of financial position and as an operating expense in the statements of comprehensive income.

The long-term portion of “Provision for employee benefits” of the statement of financial position is the best estimate of the liability that resulted from the tax assessments determined by the Tax Administration in prior years income tax calculation review.

F-200

Notes to the Financial Statements (continue)

(o)   Borrowing cost -

Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset are capitalized as finance costs as part of the asset. A qualifying asset is one whose value is greater than US$ 1 million and requires at least 12 months to be ready for its intended use. All other borrowing costs are expensed in the period in which they occur. Borrowing costs consist of interest and other costs that the Company incurs in connection with the borrowing of funds.

(p)   Fair value measurement -

The Company measures embedded derivatives at fair value as of each date presented in the statements of financial position.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data is available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described, as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

-      Level 1 — Quoted (unadjusted) market prices in active markets for identical assets or liabilities.

-      Level 2 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable.

-      Level 3 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy as explained above.

(q)   Basic and diluted earnings per share -

Basic and diluted earnings per share have been calculated based on the weighted average number of common shares outstanding during the period. When the number of shares is modified because of capitalization of retained earnings, the net income per basic and diluted shares is adjusted retroactively for all of the periods reported. For the years ended December 31, 2021, 2020 and 2019, the Company did not have any financial instruments with dilutive effects; as a result, the basic and diluted shares are the same in all periods presented.

(r)   Changes in accounting policies and disclosures –

Below is a summary of the changes in accounting policies and applicable disclosures for the year 2021:

- Interest Rate Benchmark Reform - Phase 2: Amendments to IFRS 9, IAS 39, IFRS 7, IFRS 4 and IFRS 16 -

The amendments provide temporary reliefs which address the financial reporting effects when an interbank offered rate (IBOR) is replaced with an alternative nearly risk-free interest rate (RFR). The amendments include the following practical expedients:

- A practical expedient to require contractual changes, or changes to cash flows that are directly required by the reform, to be treated as changes to a floating interest rate, equivalent to a movement in a market rate of interest.

- Permit changes required by IBOR reform to be made to hedge designations and hedge documentation without the hedging relationship being discontinued.

F-201

Notes to the Financial Statements (continue)

- Provide temporary relief to entities from having to meet the separately identifiable requirement when an RFR instrument is designated as a hedge of a risk component.

As described in Note 10(a) the interest on the credit facility is based on London Interbank Offered Rate which will be published until June 30, 2023. As the credit facility will mature on June 19, 2022, these amendments had no impact on the financial statements of the Company. The Company intends to use the practical expedients in future periods if they become applicable.

- Covid-19-Related Rent Concessions beyond 30 June 2021 Amendments to IFRS 16 -

On May 28, 2020, the IASB issued Covid-19-Related Rent Concessions - amendment to IFRS 16 “Leases”. The amendments provide relief to lessees from applying IFRS 16 guidance on lease modification accounting for rent concessions arising as a direct consequence of the Covid-19 pandemic. As a practical expedient, a lessee may elect not to assess whether a Covid-19 related rent concession from a lessor is a lease modification. A lessee that makes this election accounts for any change in lease payments resulting from the Covid-19 related rent concession the same way it would account for the change under IFRS 16, if the change were not a lease modification.

The amendment was intended to apply until June 30, 2021, but as the impact of the Covid-19 pandemic is continuing, on March 31, 2021, the IASB extended the period of application of the practical expedient to June 30, 2022.The amendment applies to annual reporting periods beginning on or after April 1, 2021.

However, the Company has not received Covid-19-related rent concessions but plans to apply the practical expedient if it becomes applicable within the allowed period of application.

Several other amendments and interpretations were first applied in 2021, but they had no impact on the Company's financial statements and therefore have not been discussed herein. The Company has not early adopted any standard, interpretation or amendment that has been issued but is not yet effective.

(s)   Standards issued but not effective -

Below is a summary of the improvements and / or modifications to IFRS that are not yet effective, but would be applicable to the Company:

- Amendments to IAS 1: Classification of Liabilities as Current or Non-current -

In January 2020, the IASB issued amendments to paragraphs 69 to 76 of IAS 1 to specify the requirements for classifying liabilities as current or non-current. The amendments clarify:

● What is meant by a right to defer settlement

● That a right to defer must exist at the end of the reporting period in order to classify liabilities as non-current.

● That classification is unaffected by the likelihood that an entity will exercise its deferral right

● That only if an embedded derivative in a convertible liability is itself an equity instrument would the terms of a liability not impact its classification

The amendments are effective for annual reporting periods beginning on or after January 1, 2023, and must be applied retrospectively. The Company is currently assessing the potential impact the amendments will have on current practice.

- Onerous Contracts – Costs of Fulfilling a Contract - Amendments to IAS 37 -

In May 2020, the IASB issued amendments to IAS 37, “Provisions, Contingent Liabilities and Contingent Assets,” to specify which costs an entity needs to include when assessing whether a contract is onerous or loss-making.

The amendments apply a “directly related cost approach.” The costs that relate directly to a contract to provide goods or services include both incremental costs and an allocation of costs directly related to contract activities. General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract.

F-202

Notes to the Financial Statements (continue)

The amendments are effective for annual reporting periods beginning on or after January 1, 2022. The Company will apply these amendments to contracts for which it has not yet fulfilled all its obligations at the beginning of the annual reporting period in which it first applies the amendments.

- IFRS 9 Financial Instruments: fees in the ’10 percent’ test to assess whether to derecognize a financial liability -

As part of the annual improvements to IFRS Standards 2018-2020, the IASB issued an amendment to IFRS 9. The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by the borrower or lender on behalf of the other. An entity applies the amendment to financial liabilities that are amended or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment.

The amendment is effective for annual periods beginning on or after January 1, 2022, with early application permitted. The Company will apply the modifications to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the entity applies the modification for the first time.

- Definition of Accounting Estimates - Amendments to IAS 8

In February 2021, the IASB issued amendments to IAS 8, “Accounting Policies, changes in Accounting Estimates and Errors,” in which it introduces a definition of “accounting estimates.” The amendments clarify the distinction between changes in accounting estimates and changes in accounting policies and the correction of errors. Also, they clarify how entities use measurement techniques and inputs to develop accounting estimates.

The amendments are effective for annual reporting periods beginning on or after January 1, 2023, and apply to changes in accounting policies and changes in accounting estimates that occur on or after the start of that period. Earlier application is permitted as long as this fact is disclosed.

The amendments are not expected to have a material impact on the Company.

- Disclosure of Accounting Policies - Amendments to IAS 1 and IFRS Practice Statement 2

In February 2021, the IASB issued amendments to IAS 1 and IFRS Practice Statement 2. “Making Materiality Judgements,” in which it provides guidance and examples to help entities apply materiality judgements to accounting policy disclosures. The amendments aim to help entities provide accounting policy disclosures that are more useful by replacing the requirement for entities to disclose their ‘significant’ accounting policies with a requirement to disclose their ‘material’ accounting policies and adding guidance on how entities apply the concept of materiality in making decisions about accounting policy disclosures.

The amendments to IAS 1 are applicable for annual periods beginning on or after January 1, 2023 with earlier application permitted. Since the amendments to the Practice Statement 2 provide non-mandatory guidance on the application of the definition of ‘material’ to accounting policy information, an effective date for these amendments is not necessary.

The Company is currently assessing the impact of the amendments to determine the impact they will have on the Company’s accounting policy disclosures.

(t)    Reclassifications of comparative information -

Management has made reclassifications in the statement of financial position as of December 31, 2020, in order to be consistent in the presentation of the financial statements as of December 31, 2021, which are summarized below:

- The Company reclassified US$ 6.3 million from "Accounts payable, short term" to "Other accounts payable, short term" relating to the presentation of penalties of INGEMMET (Instituto Geológico Minero y Metalúrgico) associated with unexploited mining concessions.

F-203

Notes to the Financial Statements (continue)

- The Company reclassified US$5.9 million from "Accounts payable, short term" to "Other accounts payable, short term" relating to the presentation of payroll withholdings (pension funds, payroll withholding income tax and others) to be paid to third party agencies.

(a) Cash equivalents as of December 31, 2021, includes a portfolio of investments in highly marketable liquid investments (mainly investments classified as “AAA” by Standard & Poor’s and Moody’s) which yield variable returns, and are classified as cash equivalents because they are readily convertible to known amounts of cash and management plans to use them for its short-term cash needs. In addition to the portfolio of investments, cash equivalents as of December 31, 2020, includes short-term deposits with Scotiabank Peru of US$ 125.0 million and Citibank NY of US$ 92.3 million. Because of the short maturity of these investments (i.e., less than 90 days), the carrying amount of these investments corresponds to their fair value at the date of the financial statements. Changes in the fair value of these investments are insignificant.

Total non-current	231,451	307,974

(a)   The provision for social commitments is associated with repaving the Alata-Congata Road (US$6.3 million as of December 31, 2021 and 2020) and an irrigation project in La Joya (US$4.4 million as of December 30, 2021 and 2020).

(b)   The Company’s mineral exploitation activities are subject to environmental protection standards. In order to comply with these standards, the Company has obtained the approval for the Environment Adequacy Program (PAMA) and for the Environmental Impact Studies (EIA), required for the operation of Cerro Verde’s production unit.

On October 14, 2003, Law 28090 was enacted, which regulates the commitments and procedures that entities involved in mining activities must follow in order to prepare, file and implement a mine site closure plan, as well as the respective environmental guarantees that assure compliance with the plan in accordance with protection, conservation and restoration of the environment. On August 15, 2005, the regulations regarding this law were approved.

During 2006, in compliance with the mentioned law, the Company completed the closure plans for its mine site and presented these plans to the Ministry of Energy and Mines.

The closure plans for its mine site were approved by Resolution No 302-2009 MEM-AAM and its modifications were approved by Resolution No 207-2012 MEM-AAM, Resolution No 186-2014 MEM-DGAAM and its last modification, Resolution No 032-2018 MEM-DGAAM. As of December 31, 2021, pursuant to legal requirements, the Company has issued a letter of credit to the Ministry of Energy and Mines totaling US$68.2 million to secure mine closure plans.

The estimate of remediation and mine closure costs is based on studies prepared by independent consultants and based on current environmental regulations. This provision corresponds mainly to the activities to be performed in order to restore the areas affected by mining activities. The main tasks to be performed include ground removal, soil recovery, and dismantling of plant and equipment.

As of December 31, 2021, the Company’s provision for remediation and mine closure was US$222.9 million (reflecting the future value of the provision for remediation and mine closure of US$374.3 million, discounted using an annual risk-free rate of 1.93%). As of December 31, 2020, the Company’s provision for remediation and mine closure was US$237.5 million (reflecting the future value of the provision for remediation and mine closure of US$374.4 million, discounted using an annual risk-free rate of 1.56%). The Company considers this liability sufficient to meet the current environmental protection laws approved by the Ministry of Energy and Mines.

As of December 31, 2021 and 2020, changes in estimates (a decrease of US$18.3 million and an increase of US$37.6 million, respectively) mainly corresponded to changes in the annual credit-adjusted, risk-free interest rate.

Notes to the Financial Statements (continue)

As of December 31, 2021, the Company’s capital stock structure is as follows:

Percentage of individual interest in capital	Number of shareholders	Total percentage interest
Up to 1.00	2,300	4.80
From 1.01 to 20.00	2	20.64
From 20.01 to 30.00	1	21.00
From 30.01 to 60.00	1	53.56
	2,304	100.00

(b)  Other capital reserves -

Other capital reserves include the Company’s legal reserve, which is in accordance with the Peruvian Companies Act, and is created through the transfer of 10% of the earnings for the year up to a maximum of 20% of the paid-in capital (US$198.1 million as of December 31, 2021 and 2020). The legal reserve must be used to compensate for losses in the absence of non-distributed earnings or non-restricted reserves, and transfers made to compensate for losses must be replaced with future earnings. This legal reserve may also be used to increase capital stock, but the balance must be restored from future earnings.

(c)  Dividend Distribution -

Beginning January 1, 2017, dividends paid to shareholders, other than domiciled legal entities, are subject to withholding of income tax at a rate of 5.0%.

At the annual mandatory shareholders meeting held on March 23, 2021, shareholders approved a US$200 million dividend payment (US$0.571337 per common share). The total amount of this dividend was applied against retained earnings. This dividend was paid on April 29, 2021 and complied with the withholding tax rules (4.1%).

At a Board Meeting held on December 2, 2021, the distribution of a dividend of US $500 million (US$1.428343 per common share) was approved. The total amount of this dividend was applied against retained earnings. This dividend was paid on December 29, 2021 and complied with the withholding tax rules (4.1)% (see Note 9(b)).

During 2020 there was no dividends distribution.

(d)Stock-based compensation -

In accordance with the Senior Executive Plan (SEP), stock-based compensation related to the common stock of the ultimate parent (Freeport) is granted to the Company’s senior executives. Amounts presented in “Other capital reserves” in the statement of change in equity totaled US$11.7 million as of December 31, 2021, US$11.5 million as of December 31, 2020, and US$10.1 million as of December 31, 2019. The fair value of stock options is determined using the Black-Scholes-Merton option pricing model. The fair value of restricted share units (RSUs) is based on Freeport's share price on the grant date. Shares of Freeport’s common stock are issued at the vesting date of RSUs settled in shares. The fair value of performance share units (PSUs) is determined using Freeport's stock price and a Monte-Carlo simulation model.

Stock options granted under such plans generally expire 10 years after the grant date. Stock options granted prior to 2018 generally vest in 25% annual increments; beginning in 2018, awards granted vest in 33% annual increments beginning one year from the date of grant. Stock option agreements provide that participants will receive the following year’s vesting upon retirement. Therefore, on the grant date, the Company accelerates one year of amortization for retirement-eligible employees. Stock options provide for accelerated vesting only upon certain qualifying terminations of employment within one year following a change of control.

The Company recognizes the compensation cost in the statement of comprehensive income during the award period according to the fair value of the instruments granted. The cost is recognized as an equity contribution in “Other capital contributions.”

Upon approval of this stability agreement, the Company became subject to the tax, administrative and exchange regulations in force on July 17, 2012, for a period of 15 years, beginning January 1, 2014, and ending December 31, 2028.

(b) Under its current 15-year tax stability agreement, the Peruvian income tax rate applicable to the Company is 32%. As of December 31, 2021, the Company has recorded income tax benefits which it expects to use to offset future income tax provisions or will be refunded by SUNAT, totaled US$19.3 million (US$13.7 million as of December 31, 2020) (see Note 6).

For the year ended December 31, 2021, the Company recognized current income tax expense of US$704.5 million (including US$74.6 million of mining royalties, US$70.3 million for special mining, and US$8.8 million for the SRF), and a deferred income tax expense of US$31.2 million, resulting in a total income tax expense of US$735.7 million that has been included in the statements of comprehensive income.

For the year ended December 31, 2020, the Company recognized current income tax expense of US$210.6 million (including US$17.3 million for special mining, US$14.9 million of mining royalties, and US$2.6 million for the SRF), and a deferred income tax expense of US$26.3 million, resulting in a total income tax expense of US$236.9 million that has been included in the statements of comprehensive income.

For the year ended December 31, 2019, the Company recognized current income tax expense of US$156.5 million (including US$28.4 million of mining royalties, US$18.6 million of special mining tax and US$1.8 million for the SRF), and a deferred income tax expense of US$141.6 million, resulting in total income tax expense of US$298.1 million that has been included in the statements of comprehensive income.

(c)   SUNAT has the right to examine, and if necessary, amend the Company’s income tax return for the last four years. The Company’s income tax for the years 2016 through 2020 are open to examination by the tax authorities and the year 2016 is currently being examined. To date, SUNAT has concluded its review of the Company’s income tax through the year 2015 and the Company is in the claim and/or appeal process for the years 2003 through 2014.

Due to the many possible interpretations of current legislation, it is not possible to determine whether or not future reviews (including reviews of years pending examination) will result in additional tax liabilities for the Company. If management determines it is more likely than not that additional taxes are payable, these amounts, including any related interest and penalties, will be charged to expense in that period. In management’s and its legal advisors’ opinions, any possible tax settlement is not expected to be material to the financial statements.

(d)   Royalties and special mining taxes –

On June 23, 2004, Law 28528 was approved, which requires the holder of a mineral concession to pay a royalty in return for the exploitation of metallic and non-metallic minerals. The royalty is calculated using rates ranging from 1% to 3% of the value of concentrate or its equivalent according to the international price of the commodity published by the Ministry of Energy and Mines. Prior to January 1, 2014, the Company determined that these royalties were not applicable because it operated under the 1998 Stability Agreement with the Peruvian government. However, beginning January 1, 2014, the Company began paying royalties calculated on operating income with rates between 1% to 12% and a new special mining tax for its entire production base under its current 15-year tax stability agreement, which became effective January 1, 2014. The

F-217

Notes to the Financial Statements (continue)

amount paid for the mining royalty is the greater of a progressive rate of the quarterly operating income or 1% of quarterly sales.

SUNAT assessed mining royalties on materials processed by the Company´s concentrator, which commenced operations in late 2006. These assessments cover the period December 2006 to December 2013. The Company contested each of these assessments because it considers that its 1998 Stability Agreement exempts from royalties all minerals extracted from its mining concession, irrespective of the method used for processing such minerals. No assessments can be issued for years after 2013, as the Company began paying royalties on all of its production in January 2014 under its new 15-year stability agreement.

Since 2017, the Company has recognized the related expense for the royalty and special mining tax assessments for the period December 2006 through the year 2013. Since 2014, the Company has been paying the disputed assessments under protest for the period from December 2006 through December 2013 under installment payment programs granted through scheduled monthly installments. In August 2021, the Company decided to pay in advance and under protest the total pending installments debt. As of December 31, 2021, the Company has made total payments of S/2.9 billion under these installment programs (US$791.9 million based on the date of payment exchange rate).

During February 2020, the Company requested the initiation of an arbitration proceeding against the Republic of Peru before the International Centre for Settlement of Investment Disputes and on October 19, 2021, the Company formally filed the arbitration claim.

On March 31, 2021, Superintendence Resolution 044-2021/SUNAT was published in which new default monthly interest rates were established effective April 1, 2021. The default interest rate in national currency changes from 1% to 0.9%.

(e)   Other assessments received from SUNAT and other regulatory entities -

The Company has also received assessments from SUNAT for additional taxes (other than the mining royalty and special mining tax explained in Note 13(d) above), including penalties and interest. The Company has filed objections to the assessments because it believes it has properly determined and paid its taxes. A summary of these assessments follows:

Year	Taxes	Penalty and interest	Total
	US$(000)	US$(000)	US$(000)
2003 – 2005	8,684	39,402	48,086

2016	4,202	2,652	6,854
	252,412	468,400	720,812

As of December 31, 2021, the Company has paid a total of US$641.3 million of which US$236.5 million (US$190.5 million as of December 31, 2020) is included in “Other non-financial assets, non-current” (see Note 6) in the statements of financial position for these disputed tax assessments. The Company believes this amount is recoverable.

20.  Financial risk management

The Company’s activities are exposed to different financial risks. The main risks that could adversely affect the Company’s financial assets and liabilities or future cash flows are: (i) market risk, (ii) credit risk, (iii) interest rate risk, (iv) liquidity risk, and (v) capital risk. The Company’s financial risk management program focuses on mitigating potential adverse effects on its financial performance.

Management knows the conditions prevailing in the market and based on its knowledge and experience, manages the risks that are summarized below. The Company’s Board of Directors reviews and approves the policies to manage each of these risks:

(a) Market risk -

Commodity price risk -

The international price of copper has a significant impact on the Company’s operating results. The price of copper has fluctuated historically and is affected by numerous factors beyond the Company’s control. The Company does not hedge its exposure to price fluctuation.

As described in Note 2(d), the Company has price risk through its provisionally priced sales contracts, which provide final pricing in a specified future month (generally between three and six months after the shipment's arrival date) based primarily on quoted LME monthly average prices. The Company records revenues and invoices customers at the time of shipment based on then-current LME prices, which results in an embedded derivative on the provisionally priced contract that is adjusted to fair value through revenues each period, using the period-end forward prices, until the date of final pricing. To the extent that final prices are higher or lower than what was recorded on a provisional basis, an increase or decrease to revenues is recorded each reporting period until the date of final pricing (see Note 21).

The table below summarizes the estimated impact on the Company’s profit before income tax for the year 2021, 2020 and 2019 based on a 10% increase or decrease in future copper price while all other variables are held constant. The 10% increase is based on copper prices ranging from US$/pound 4.765 to US$/pound 4.879 (US$/pound 3.524 to US$/pound 3.876, as of December 31, 2020 and US$/pound 2.865 to US$/pound 3.085 as of December, 31 2019 and the 10% decrease is based on copper prices ranging from US$/pound 3.899 to US$/pound 3.992 (US$/pound 2.884 to US$/pound 3.172, as of December 31, 2020 and US$/pound 2.344 to US$/pound 2.524 as of December 31, 2019).

Exchange rate risk -

As described in Note 2(c), the Company’s financial statements are presented in US dollars, which is the functional and presentation currency of the Company. The Company’s exchange-rate risk arises mainly from balances related to tax payments (including installment programs), deposits and other accounts payable in currencies other than the US dollar, principally soles. The Company mitigates its exposure to exchange-rate risk by carrying out almost all of its transactions in

F-225

Notes to the Financial Statements (continue)

its functional currency and management maintains only small amounts in soles to cover its immediate needs (i.e., taxes and compensation) in this currency.

A table showing the effect on results of a reasonable change in foreign-currency exchange rates is presented below, with all other variables kept constant:

	Exchange-rate		Effect on profit (loss)
	increase/decrease		before income tax
			US$(000)
2021
Exchange rate	5	%	(7,782)
Exchange rate	(5)	%	7,782
2020
Exchange rate	5	%	20,656
Exchange rate	(5)	%	(20,656)

(b) Credit Risk -

The Company's exposure to credit risk arises from a customer's inability to pay amounts in full when they are due and the failure of third parties in cash and cash equivalent transactions. The risk is limited to balances deposited in banks and financial institutions and for trade accounts receivable at the date of the statements of financial position (the Company sells copper concentrate and cathode and molybdenum concentrate to companies widely recognized in the worldwide mining sector and collections are made within 30 days after the fulfilment of the contractual terms). To manage this risk, the Company has established a treasury policy, which only allows the deposit of surplus funds in highly rated institutions, by establishing conservative credit policies and through a constant evaluation of market conditions. Consequently, as of December 31, 2021 and 2020, the Company does not have expected credit losses and does not project to have expected credit losses based on the credit profile of its clients in the mining sector.

(c) Interest rate risk -

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company's exposure to the risk of changes' in market interest rates has no significant impact taking into consideration the maturity of the credit facility (see Note 10(a)).

(d) Liquidity risk -

Liquidity risk arises from situations in which cash might not be available to pay obligations at their maturity date and at a reasonable cost. The Company maintains adequate liquidity by properly managing the maturities of assets and liabilities in such a way that allows the Company to maintain a structural liquidity position (cash available) enabling it to meet liquidity requirements. Additionally, the Company has the ability to obtain funds from financial institutions and shareholders to meet its contractual obligations.

(e) Capital risk -

The objective is to safeguard the Company’s ability to continue as a going concern in order to provide returns for shareholders, benefits for stakeholders and maintain an optimal structure that would reduce the cost of capital.

The Company manages its capital structure, and makes adjustments to it, in light of changes in economic conditions. To maintain or adjust the capital structure, the Company controls dividend payments to shareholders, the return of capital to shareholders and the issuance of new shares. No changes were made to the objectives, policies or processes during the year ended December 31, 2021.

21.  Embedded derivatives

As discussed in Note 2(d), the Company’s sales create exposure to changes in the market prices of copper and molybdenum which are considered embedded derivatives. As of December 31, 2021 and 2020, information about the Company’s embedded derivatives is as follows:

(a)   Embedded derivative adjustments are recorded on the statement of financial position in “Trade account receivable – related parties”.

22.  Hierarchy and fair value of financial instruments

Hierarchy:

As of December 31, 2021 and 2020, the only financial assets carried at fair value are embedded derivatives, included in trade accounts receivable and related parties, which are generated by the sale of copper and molybdenum and measured at fair value based on commodity prices. The net value of these embedded derivatives as of December 31, 2021, was an asset of US$12.8 million (asset of US$101.4 million as of December 31, 2020). Embedded derivatives are categorized within Level 2 of the fair value hierarchy. The fair value of embedded derivatives is determined using information directly observable in the market (forward prices of metals).

In the case of financial liabilities, the credit facility is categorized within Level 2 of the hierarchy and as of December 31, 2021, and the fair value is considered to be similar to the carrying value given the short-term mature (see Note 10(a)).

Financial instruments whose fair value is similar to their book value -

For financial assets and liabilities which are liquid or have short-term maturity (less than three months), such as cash and cash equivalent, accounts receivable, other accounts receivable, accounts payable, other accounts payable, and other current liabilities, it is estimated that their book value is similar to their fair value.

Financial instruments at fixed and variable rates -

Financial assets and liabilities with fixed or variable rates are recorded at amortized cost and fair value is determined by comparing the market interest rates at the time of their initial recognition to the current market rates for similar financial instruments.

Based on the foregoing, there are no significant differences between the book value and the fair value of financial instruments (assets and liabilities) as of December 31, 2021 and 2020.

23.   Summary of significant differences between accounting principles followed by the Company and U.S. generally accepted accounting principles (U.S. GAAP)

The Company’s financial statements have been prepared in accordance with International Financial Reporting Standards which differs in certain respects from U.S. GAAP. The effects of these differences are reflected in note 24 and are principally related to the items discussed in the following paragraphs:

(a)Stripping Cost

Under IFRS, the production stripping costs can be incurred both in relation to the production of inventory in that period and the creation of improved access and mining flexibility in relation to ore to be mined in the future. The waste removal cost is included as part of the cost of inventory, while the production stripping costs are capitalized as a stripping activity asset, if

F-228

Notes to the Financial Statements (continue)

certain criteria are met, and amortized based on proved and probable reserves of each ore body (component) identified in the open pit. See note 2b.

Under U.S. GAAP, the costs of clearing removal (production stripping costs) incurred during the production stage are recorded as part of the production cost of inventories; accordingly, such costs are recorded on the income statement at an earlier time than under IFRS.

(b)Inventories

Under IFRS, the inventory costs include the amortization of production-stripping costs. Also, inventories are valued using the weighted average method and includes the stripping activity asset and worker’s profit sharing.

Under U.S. GAAP, the inventory cost excludes the amortization of production-stripping cost and the inventories are determined using the Last-In-First-Out (LIFO) method, the worker’s profit sharing is excluded from the inventory costing.

(c)Deferred workers’ profit sharing

Under IFRS, the workers’ profit sharing is calculated based on the Company’s taxable income and is recorded as an employee benefit (cost of production or administrative expense, depending on the function of the workers).

Under US GAAP, the workers’ profit sharing is treated in a similar way as income tax since both are calculated based on the Company’s taxable income. Therefore, the Company calculates a deferred workers’ profit sharing resulting from the taxable and deductible temporary differences.

(d)Deferred income tax –

The differences between US GAAP and IFRS are re-measurements that lead to different temporary differences.

(e)Remediation and mine closure –

Under IFRS, the liability is measured in accordance with IAS 37 and IFRIC 1. Upward and downward revisions in the amount of undiscounted estimated cash flows are discounted using the current market-based discount rate (this includes changes in the time value of money and the risks specific to the liability).

Under IFRS, the Company updates the discount rate used to discount its liability at the closing date, this change in the discount rate has an impact (increase/decrease) on the book value of the asset retirement cost (ARC) and the remediation liability.

Under U.S. GAAP, upward revisions in the amount of undiscounted estimated cash flows are discounted using the current credit-adjusted risk-free rate. Downward revisions in the amount of undiscounted estimated cash flows are discounted using the credit-adjusted risk-free rate that existed when the original liability was recognized.

Under U.S. GAAP, there is no requirement to update the discount rate.

(f)Mine equipment main components -

Under IFRS, in accordance with IAS 16, the main components associated with mine equipment (primarily engines) are capitalized and depreciated based on the estimated useful lives.

Under U.S. GAAP, the Company’s policy is that those components are charged directly to the statement of comprehensive income at the time are utilized.

(g) Stock-based compensation

Under IFRS, this balance is presented as an equity item “Other equity contributions”, as disclosed in note 12(d).
Under US GAAP this balance is presented as part of the liability (Accounts payable – Related parties).

(a) As a result of additional analysis of the amounts performed in 2021, the Company identified additional reconciling differences; consequently, the related amounts for 2020 and 2019 originally reported were updated and retrospectively adjusted to be consistent to 2021 amounts. Equity for those years was retrospectively adjusted from US$5,249,727 to US$5,229,338 and US$4,972,580 to US$4,963,065, respectively. Net income for 2020 was retrospectively adjusted from US$275,686 to US$266,272, net income for 2019 had no change. These changes were mainly caused the stock-based compensation items and Mine equipment main components, which were not being considered in the reconciliation.
