Notes to Unaudited Condensed Consolidated Interim Financial Statements
(in thousands of US dollars, except where otherwise noted)
For the three and six months ended June 30, 2023 and 2022

1.Reporting entity

Hudbay Minerals Inc. ("HMI" or the "Company") is a company existing under the Canada Business Corporations Act. The address of the Company's principal executive office is 25 York Street, Suite 800, Toronto, Ontario. The unaudited condensed consolidated interim financial statements ("interim financial statements") of the Company for the three and six months ended June 30, 2023 and 2022 represent the financial position and the financial performance of the Company and its subsidiaries (together referred to as "Hudbay").

Wholly owned subsidiaries as at June 30, 2023 and 2022 include HudBay Marketing & Sales Inc. ("HMS"), HudBay Peru Inc., HudBay Peru S.A.C. ("Hudbay Peru"), HudBay (BVI) Inc., Hudbay Arizona Inc, Copper World, Inc. ("Copper World") and Mason Resources (US) Inc. ("Mason"). On June 20, 2023, the Company acquired all of the issued and outstanding common shares of Copper Mountain Mining Corporation ("Copper Mountain") as part of a court-approved plan of arrangement. Copper Mountain is currently a wholly owned subsidiary of the Company and owns 75% of Copper Mountain Mine (BC) Ltd. ("CMBC"), the entity that owns the Copper Mountain mine. Mitsubishi Materials Corporation ("MMC"), an arms-length party, owns the remaining 25% interest in CMBC.

Hudbay is a diversified mining company with long-life assets in North and South America. Hudbay's operations in Cusco (Peru) produce copper with gold, silver and molybdenum by-products. Hudbay's operations in Manitoba (Canada) produce gold with copper, zinc and silver by-products. Hudbay's operations in British Columbia (Canada) produce copper with gold and silver by-products. Hudbay has an organic pipeline that includes copper development projects in Arizona and Nevada (United States), and a focused growth strategy on exploration, development, operation, and optimization of properties that Hudbay already controls, as well as other mineral assets that Hudbay may acquire that fit the Company's strategic criteria. The Company is governed by the Canada Business Corporations Act and its shares are listed under the symbol "HBM" on the Toronto Stock Exchange, New York Stock Exchange and Bolsa de Valores de Lima.

2.Basis of preparation

(a)Statement of compliance:

These interim financial statements have been prepared in accordance with IAS 34, Interim Financial Reporting as issued by the International Accounting Standards Board ("IASB") and do not include all of the information required for full annual financial statements by International Financial Reporting Standards ("IFRS").

These interim financial statements should be read in conjunction with the Company's audited consolidated financial statements for the year ended December 31, 2022 which includes information necessary or useful to understanding the Company's business and financial statement presentation. In particular, the Company's accounting policies are presented as note 3 in the Company's audited consolidated financial statements for the year ended December 31, 2022 and have been consistently applied in the preparation of these interim financial statements, except as noted below.

As a result of the acquisition of Copper Mountain, the Company's interim financial statements also reflect  the following relevant accounting policies.

Notes to Unaudited Condensed Consolidated Interim Financial Statements
(in thousands of US dollars, except where otherwise noted)
For the three and six months ended June 30, 2023 and 2022

Non-controlling interests

Non-controlling interests in subsidiaries are identified separately from the Company's equity in the subsidiaries. The interests of non-controlling shareholders may be initially measured either at fair value or at the non-controlling interests' proportionate share of the fair value of the acquiree's identifiable net assets. The choice of measurement basis is made on an acquisition-by-acquisition basis. Subsequent to acquisition, the carrying amount of non-controlling interests is the amount of those interests at initial recognition plus the non-controlling interests' share of subsequent changes in equity. Total comprehensive income is attributed to non-controlling interests even if this results in the non-controlling interests having a deficit balance.

Impairment of non-financial assets

Goodwill is tested for impairment annually and whenever there is an indication that the asset may be impaired.

The Company performs goodwill impairment tests on an annual basis as at December 31 each year. If the carrying value of the CGU or group of CGUs to which goodwill is assigned exceeds its recoverable amount, an impairment loss is recognized. Goodwill impairment losses are recorded in the consolidated income statements and they are not subsequently reversed.

The Board of Directors approved these interim financial statements on August 8, 2023.

(b)Use of judgements and estimates:

The preparation of the interim financial statements in conformity with IFRS requires Hudbay to make judgements, estimates and assumptions, in applying accounting policies that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the interim financial statements, as well as reported amounts of revenue and expenses during the reporting period. Actual results may differ from these judgements, estimates and assumptions. The interim financial statements reflect the judgements and estimates outlined by Hudbay in its audited consolidated financial statements for the year ended December 31, 2022, except as noted below.

-Valuation of an acquired business (note 5) - As the Company concluded that the acquisition of Copper Mountain was a business combination, a valuation was required to determine the allocation of the purchase price. The fair values of the net assets acquired were calculated using significant estimates and judgements. In particular, the fair values of the net assets, including mineral properties, other property, plant and equipment have been determined using an independent valuation involving discounted cash flow calculations and other finance models. Such calculations and models were required to estimate, amongst other items, future production, future commodity prices, operating and capital input costs, discount rates and currency rates. If estimates or judgements differed, this could result in a materially different allocation of net assets to the consolidated balance sheets and could result in a change in the amount of goodwill recognized. Changes to the preliminary values of  assets  acquired  and  liabilities  assumed,  deferred  income  taxes  and  resulting  goodwill,  if  any,  are retrospectively adjusted when the final measurements are determined if related to conditions existing at the date of acquisition (within one year of acquisition).

-Inventory valuation (note 8) - Stockpiled ore and concentrate inventory are valued at the lower of average cost and net realizable value. Net realizable value is calculated as the estimated price at the time of sale based on prevailing and future metal prices less estimated future processing costs to convert the inventory into salable form and the associated selling costs. Where inventory is to be processed more than one year in the future, the estimate of net realizable value is based on a discounted cash flow projection. The determination of future sales price, processing and selling costs requires assumptions that may impact the stated value of inventory. Because the low grade inventory net realizable value measurement involves discounting, any significant changes in the projected timing of processing of the stockpile could result in significant impairment charges or reversals.

Notes to Unaudited Condensed Consolidated Interim Financial Statements
(in thousands of US dollars, except where otherwise noted)
For the three and six months ended June 30, 2023 and 2022

(c)Estimation uncertainty:

The Company has assessed the broad implications of economic uncertainty including but not limited to inflation and higher interest rates, political instability in Peru and broadly as a result of Russia's invasion of Ukraine, as well as the lingering impact of the novel coronavirus pandemic, on its condensed consolidated interim financial statements. As at June 30, 2023, management has determined that the Company's ability to execute its medium and longer term plans and the economic viability of its assets, including the carrying value of its long-lived assets and inventory valuations, are not materially impacted.

In making this judgment, the Company has assessed various criteria including, but not limited to, existing laws, regulations, orders, disruptions and potential disruptions in our supply chain, disruptions in the markets for our products, commodity prices and foreign exchange prices and the actions that the Company has taken at its operations to protect the health and safety of its workforce and local community.

3.Reclassification of comparative amounts

Certain prior period amounts have been reclassified for consistency with the current period presentation. Community agreement payments were previously included within acquisition of property, plant and equipment in the investing activities section of the condensed consolidated interim statements of cash flows and has now been reclassified to its own line within investing activities. This reclassification had no effect on the previously reported cash used in investing activities.

4.New standards

New standards and interpretations adopted

(a)Amendment to IAS 1 - Presentation of Financial Statements and IFRS Practice Statement 2 Making Materiality Judgements

The amendments to IAS 1 amendments help companies provide useful accounting policy disclosures. The adoption of the new standard effective January 1, 2023 did not impact the interim financial statements of the Company.

New standards issued but not yet effective

(b)Amendment to IAS 1 - Presentation of Financial Statements

The amendments to IAS 1 clarify that only covenants with which an entity is required to comply on or before the reporting date affect the classification of a liability as current or non-current. In addition, an entity has to disclose information in the notes that enables users of financial statements to understand the risk that non-current liabilities with covenants could become repayable within twelve months. Classification is unaffected by the expectations that the entity will exercise its right to defer settlement of a liability. Lastly, the amendments clarify that settlement refers to the transfer to the counterparty of cash, equity instruments, other assets. The amendments are effective for annual periods beginning on or after January 1, 2024. Earlier application is permitted.

5.Acquisition of Copper Mountain Mining Corporation

On June 20, 2023, Hudbay acquired all of the issued and outstanding common shares of Copper Mountain, as part of a court-approved plan of arrangement. Copper Mountain is currently a wholly owned subsidiary of the Company and owns 75% of CMBC, the entity that owns the Copper Mountain mine. MMC owns the remaining 25% interest in CMBC as a non-controlling interest.

In doing so, Hudbay obtained control of Copper Mountain on June 20, 2023.

Management determined that the assets and processes comprised a business and therefore accounted for the transaction as a business combination, using the acquisition method of accounting.

Consideration transferred:

The purchase consideration paid by Hudbay was for 100% of the net assets of Copper Mountain and their 100% owned subsidiaries ("100% owned entities") and a 75% ownership in CMBC. The aggregate preliminary purchase consideration for the acquired assets, net of the liabilities assumed is as follows:

Equity instruments (84,165,617 common shares)	$	436,687
Cash		3,794
Consideration transferred - June 20, 2023	$	440,481

The fair value of the common shares issued was based on Hudbay's listed share price of C$6.87 at the June 20, 2023 acquisition date. Immediately prior to the acquisition, Copper Mountain settled its outstanding restricted share units and performance share units through the issuance of shares and settled its stock options for replacement Hudbay options that were immediately settled in cash.

Hudbay incurred acquisition related costs of $6,752 during the second quarter of 2023, mainly relating to external legal and advisory fees and due diligence costs, which were recorded in other expense in the condensed consolidated interim income statements. Transaction costs incurred by Copper Mountain were accrued prior to the acquisition date and were expensed in their pre-acquisition records. In addition, Hudbay incurred share issuance costs of $188 and presented these as a deduction from share capital.

Identifiable assets acquired and liabilities assumed:

The fair value of the net assets was determined using a combination of market, income and cost methods. The fair value of the 75% equity interest in CMBC was determined by first computing the equity value of the 100% owned entities and subtracting this from the consideration paid by Hudbay and then grossing up the remainder to determine the implied consideration for a 100% equity interest in CMBC. The fair value of the non-controlling interest was then computed at a 25% equity interest.

For the three and six months ended June 30, 2023 and 2022

The following presents the preliminary allocation of the purchase price, resulting in recognized fair value amounts of identifiable assets acquired and liabilities assumed as follows: 

Fair value of net assets acquired / (liabilities) assumed		Preliminary
Cash and cash equivalent	$	14,483
Trade and other receivables		19,110
Inventories		47,875
Prepaid expenses		3,096
Other financial assets		8,495
Plant and equipment		434,419
Mineral properties		383,000
Inventories - low grade stockpile		6,000
Trade and other payables		(77,111	)
Advances from Hudbay		(3,421	)
Lease liabilities		(44,167	)
Long-term debt		(144,981	)
Environmental and other provisions		(12,702	)
Deferred tax liabilities		(153,208	)
Total fair value of net identifiable assets acquired	$	480,888

The fair values allocated to assets acquired and liabilities assumed are preliminary, and are subject to adjustment based on further analysis and evaluation over the course of the measurement period, which will not exceed twelve months from the acquisition date. Where preliminary values are used in accounting for a business combination, they may be materially adjusted retrospectively in subsequent periods. In particular, the Company will continue to evaluate new information about the facts and circumstances that existed as of the acquisition date pertaining to the fair value of property, plant and equipment, low grade stockpile, mineral properties, goodwill, reclamation provisions and deferred income and mining tax liabilities.

The fair values of mineral properties, low grade stockpile and other property, plant and equipment have been determined based on an independent valuation, using a combination of market, income and cost methods. In particular, the fair values of the mineral properties and low grade stockpile have been calculated using significant judgements and estimates.

Trade receivables acquired as part of the acquisition have a fair value of $8,764 which is equal to their gross contractual value. Other receivables acquired have a fair value of $10,346 million which is equal to their gross contractual value. Trade and other receivables are expected to be collected during the next 12 months.

Hudbay provided advances to Copper Mountain prior to the acquisition date, which have been recorded as a purchaser loan.

Hudbay recognized goodwill as a result of the acquisition as follows:

Total consideration transferred	$	440,481
Non-controlling interest		106,976
Less: value of net identifiable assets acquired		(480,888	)
Goodwill upon acquisition at June 20, 2023	$	66,569

The goodwill balance arose from the requirement to record deferred income tax liabilities measured at the tax effect of the difference between the fair values of the assets acquired and liabilities assumed and their tax bases. None of the goodwill recognized is expected to be deductible for income tax purposes.

The results of operations have been consolidated with those of the Company from the date of acquisition and included in the British Columbia operating segment, however, second quarter 2023 loss was not materially affected as Copper Mountain had no revenues or corresponding cost of sales recorded during the 10 day stub period from the date of acquisition to the end of the second quarter. Had the business combination been effected at January 1, 2023, revenue and net loss contributed from the acquisition of Copper Mountain for the six months ended June 30, 2023, would have been $132,227 and a loss of $40,260, respectively.

Consideration from the Company's stream agreements is considered variable (note 17). Gold and silver stream revenue can be subject to cumulative adjustments when the amount of precious metals to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2023, the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a variable consideration adjustment was made for all prior year stream revenues since the stream agreement inception date. This variable consideration adjustment resulted in an increase of revenue of $4,885 for the six months ended June 30, 2023 (June 30, 2022 - increase of revenue of $3,245).

    (b)Depreciation and amortization

  (e)Impairment loss

As a result of the Copper World Complex preliminary economic assessment released in June 2022, which contemplates the mining of the Copper World deposits and the Rosemont deposit in a two-phase mine plan, it was determined that certain capitalized costs and assets associated with the previous stand-alone development plan for the Rosemont deposit are no longer recoverable. As a result, during the second quarter of 2022, the Company recognized a pre-tax impairment loss of $94,956 related to these assets. The impairment loss was determined based on the specific identification of assets that are not expected to be recoverable under the Copper World Complex PEA. The Company presented the impairment losses within the Arizona segment in note 25. The fair value measurements used in the determination of impairment charges are categorized as level 2 based on the degree to which inputs are observable and have a significant effect on the recorded fair value.

The increase in derivative assets is the result of unrealized gains in copper and zinc fixed for floating swaps and costless copper collars following a decline in base metal prices during the second quarter of 2023. See note 22b.

Restricted cash is primarily related to a debt service reserve account used to satisfy the $5.0 million semi-annual principal installment and interest payments under the Bonds (note 16).

The Company has $2,013 in reclamation bonds with the Government of British Columbia in support of reclamation liabilities at the Copper Mountain mine site. The Company receives interest on these bonds.

10.Intangibles and other assets

Intangibles and other assets of $47,042 (December 31, 2022 - $49,841) includes $42,861 of other assets (December 31, 2022 - $45,074) and $4,181 of intangibles (December 31, 2022 - $4,767).

Other assets represent the carrying value of certain future community costs that relate to agreements with communities near the Peru operations which allow Hudbay to extract or explore minerals over the useful life of Peru operations. The liability remaining for these costs is recorded in agreements with communities recorded at amortized cost (note 13). Amortization of the carrying amount is recorded in the condensed consolidated interim income statements within other expenses (note 6c) or exploration expenses, depending on the nature of the agreement.

Intangibles mainly represent computer software costs.

¹ Includes $5,493 of capital works in progress - ROU assets (cost) that relate to the Arizona segment (December 31, 2022 - $5,413 related to the Arizona segment).

An indicator of impairment was identified in the three months ended March 31, 2023 as a result of an updated life of mine ("LOM") plan for Peru, which included updated costs reflecting recently experienced inflationary pressures. As such, management determined that a detailed impairment evaluation as at March 31, 2023 was required for the Peru CGU.

For the impairment test completed at March 31, 2023, Fair Value Less Cost of Disposal, ("FVLCD") was used to determine the recoverable amount since it is higher than value in use. FVLCD was calculated using discounted after-tax cash flows based on cash flow projections and assumptions in Hudbay's most current LOM. The fair value measurement in its entirety is categorized as Level 3 based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value.

LOM plans are based on optimized mine and processing plans and the assessment of capital expenditure requirements of a mine site. LOM plans incorporate management's best estimates of key assumptions which are discount rates, future commodity prices, production based on current estimates of recoverable reserves, future operating and capital costs, value of mineral resources not included in the LOM plan and future foreign exchange rates. The cash flows are for periods up to the date that production is expected to cease, which is 16 years for the Peru CGU.

The discount rate was based on the CGU's weighted average cost of capital, of which the two main components are the cost of equity and the after-tax cost of debt. Cost of equity was calculated based on the capital asset pricing model, incorporating the risk-free rate of return based on the US Government's marketable bond yields as at the valuation date, the Company's beta coefficient adjustment to the market equity risk premium based on the volatility of the Company's return in relation to that of a comparable market portfolio, plus a country risk premium, size premium and company-specific risk factor. Cost of debt was determined by applying an appropriate market indication of the Company's borrowing capabilities and the corporate income tax rate applicable to the segment's jurisdiction. A real discount rate of 7.00% for the Peru CGU was used to calculate the estimated after- tax discounted future net cash flows, commensurate with its individual estimated level of risk.

For the three and six months ended June 30, 2023 and 2022

Commodity prices used in the impairment assessment were determined by reference to external market participant sources. The key commodity price for this assessment is the price of copper. Where applicable to each of the Group's CGUs, the cash flow calculations were based on estimates of future production levels applying forecasts for metal prices, which included forecasts for each year from 2023 to 2027 and long-term forecasts for years beginning in 2028. The cash flow calculations utilized a copper price of $3.75/lb starting in 2023. The cash flow calculations utilized a long-term copper price of $3.75/lb, and capital, operating and reclamation costs based on the most current LOM plans. A value of $210,000 was utilized to estimate the value of mineral resources not included in the LOM plan.

Expected future cash flows used to determine the FVLCD used in the impairment testing are inherently uncertain and could materially change over time. Should management's estimate of the future not reflect actual events, impairments may be identified. This may have a material effect on the Company's financial statements. Although it is reasonably possible for a change in key assumptions to occur, the possible effects of a change in any single assumption may not fairly reflect the impact on a CGU's fair value as the assumptions are inextricably linked. For example, a decrease in the assumed price of long-term copper could result in amendments to the mine plans which would partially offset the effect of lower prices. It is difficult to determine how all of these factors would interrelate; however, in deriving a recoverable amount, management believes all of these factors need to be considered. As of March 31, 2023, a reasonably possible change in one of the key assumptions, all else being equal, may cause the carrying value to exceed the recoverable amount.

Management determined that the fair value less cost to dispose exceeded the carrying value of the Peru CGU, accordingly no impairment was recorded.

Hudbay has entered into leases which expire between 2023 and 2037. The interest rates on leases which were capitalized have interest rates between 2.39% and 8.49%, per annum. The range of interest rates utilized for discounting varies depending mostly on the Hudbay entity acting as lessee and duration of the lease. For certain leases, Hudbay has the option to purchase the equipment and vehicles leased at the end of the terms of the leases. Hudbay's obligations under these leases are secured by the lessor's title to the leased assets. The present value of applicable lease payments has been recognized as an ROU asset, which was included as a non-cash addition to property, plant and equipment, and a corresponding amount as a lease liability.

There are no restrictions placed on Hudbay by entering into these leases.

The following outlines expenses recognized within the Company's condensed consolidated interim income statements, relating to leases for which a recognition exemption was applied.

		Three months ended June 30, 2023				Six months ended June 30, 2023

Payments made for short-term, low value and variable leases would mostly be captured as expenses in the condensed consolidated interim income statements, however, certain amounts may be capitalized to PP&E for the Arizona segment during its development phase and certain amounts may be reported in inventories given the timing of sales. Variable payment leases include equipment used for heavy civil works at Constancia.

During the first quarter of 2023, Hudbay drew $40,000 under its Canadian revolving credit facility, which remains outstanding as of June 30, 2023.

The Company may repay any borrowings under the revolving credit facility at any time without premium or penalty.

In connection with the Copper Mountain Transaction, our revolving credit facilities ("RCFs") were amended to allow Hudbay to designate the Copper Mountain Group of companies as Unrestricted Subsidiaries under the RCFs so that the debt, cash, interest and EBITDA are excluded from ratio calculations and the assets excluded from the RCF security package until the Copper Mountain bonds are repaid in full. In addition, the Net Debt to EBITDA covenant ratio was increased from 4:1 to 4.5:1 for the periods ending June 30 and September 30, 2023, to provide greater financial flexibility during the business integration period.

As at June 30, 2023, the Peru segment had nil in letters of credit issued under the Peru revolving credit facility to support its reclamation obligations and the Manitoba segment had $26,116 in letters of credit issued under the Canadian revolving credit facility to support its reclamation and pension obligations.

Surety bonds

The Arizona segment had $12,835 in surety bonds issued to support future reclamation and closure obligations. No cash collateral is required to be posted under these surety bonds.

The British Columbia segment had $15,909 in surety bonds issued to support future reclamation and closure obligations. There is also a financial guarantee bond for $3,875 with BC Hydro in relation to the BC Hydro transmission system at the Copper Mountain Mine. No cash collateral is required to be posted under these surety bonds.

Other letters of credit

The Peru segment had $118,049 in letters of credit issued with various Peruvian financial institutions to support future reclamation and other operating matters. No cash collateral is required to be posted under these letters of credit.

On August 22, 2022, Hudbay closed a C$130.0 million bilateral letter of credit facility ("LC Facility") with a major Canadian financial institution. As at June 30, 2023, the Manitoba segment had $58,023 in letters of credit issued under the LC Facility to support its reclamation and pension obligations.

(c)Copper Mountain Bonds

On April 9, 2021 Copper Mountain completed an offering of $250,000 of secured bonds ("the Bonds"). The Bonds mature on April 9, 2026 and bear interest at an annual rate of 8.0%, payable semi-annually on April 9 and October 9. Semi-annual principal installments in the amount of $5 million are payable on each interest payment date. As at June 30, 2023, the Company had $3,669 on deposit in a debt service account to satisfy the upcoming semi-annual principal installment and interest payment. The debt service account balance is presented as restricted cash within our condensed consolidated interim balance sheet.

The Bonds are secured by a general security agreement on the assets of Copper Mountain and a pledge of Copper Mountain's equity interest in the Copper Mountain mine, but do not benefit from any credit support from Hudbay or its other subsidiaries. The Company may redeem all or part of the principal amount of the outstanding Bonds at any time from October 2023, at redemption prices ranging from 104% to 100%, plus accrued and unpaid interest to the date of redemption. The prepayment options are not closely related to the host debt instrument and are separately accounted for as embedded derivatives. As at June 30, 2023, the value of the prepayment options was nil.

The Bonds also provide the bondholders with the right to put all or part of the principal amount of the outstanding Bonds to Copper Mountain at a price of 101%, plus accrued interest, following a change of control event. With the acquisition of Copper Mountain on June 20, 2023, the change of control event was triggered and all outstanding Bonds were available to be put to Copper Mountain within a predefined period of time immediately following the acquisition date. The Bonds are presented on the condensed consolidated interim balance sheet as the current portion of long-term debt as at June 30, 2023.

The change in control put option expired on July 17, 2023, at which time, $83,307 of the Bonds were put to Copper Mountain (note 26).

As at June 30, 2023, the Bonds have a principal amount outstanding of $143,000. Upon acquisition, the debt is recorded at its fair value as required as part of the accounting for the business combination with Copper Mountain. This fair value adjustment amortizes down to its historical cost over the duration of the facility (note 5).

The Bonds require the Copper Mountain to maintain: (a) a minimum cash amount of $10 million, on a subsidiary level, subject to the liquidity covenant step-up, as defined below; and (b) a minimum cash amount of CA$10 million at the Copper Mountain mine. The liquidity covenant step-up is defined as: in case that at the end of the quarter, the leverage ratio (defined as net debt to trailing twelve months adjusted EBITDA) exceeds 4.0:1.0, Copper Mountain shall maintain a minimum cash balance of an amount equal to (i) $25 million less (ii) an amount equal to the amount deposited in the debt service account. Cash held by Copper Mountain, in the amount of $28,883, with respect to these covenants can only be utilized for the business activities of Copper Mountain.

As at June 30, 2023, Hudbay is in compliance with our financial covenants under the Bonds.

17.Deferred revenue

Peru Stream Agreement

For the three and six months ended June 30, 2023, the drawdown rates for the Peru stream agreement for gold and silver were $820 and $15.26 per ounce, respectively (year ended December 31, 2022 - $734 and $14.95 per ounce, respectively).

777 Stream Agreement

As of September 30, 2022 all of 777's precious metals reserves and inventory levels have been depleted and we expect no further drawdown of deferred revenue. 

As part of the streaming agreement for the 777 mine, Hudbay must repay, with precious metals credits, the stream deposit by August 1, 2052, the expiry date of the agreement. If the stream deposit is not fully repaid with precious metals credits from 777 production by the expiry date, a payment for the remaining amount will be due at the expiry date of the agreement. As the 777 mine has concluded all mining activities following the depletion of reserves and finalized the sales of produced concentrate, Hudbay concluded that the remaining stream deposit will not be repaid by means of precious metals credits from 777 production. The repayment amount is recorded as a Wheaton refund liability (note 13), which is and will be discounted at the 9.0% rate inherent in the original 777 stream agreement and accreted over the remaining term of the agreement.

The following table summarizes changes in deferred revenue:

Balance, January 1, 2022	$	515,326
Amortization of deferred revenue
Liability drawdown		(72,229	)
Variable consideration adjustments - prior periods		(959	)
Accretion on streaming arrangements
Current year additions		28,718
Variable consideration adjustments - prior periods		(940	)
Effects of changes in foreign exchange		(378	)
Balance, December 31, 2022	$	469,538
Amortization of deferred revenue (note 6a)
Liability drawdown		(29,147	)
Variable consideration adjustments - prior periods		(4,885	)
Accretion on streaming arrangements (note 6d)
Current year-to-date additions		13,193
Variable consideration adjustments - prior periods		(96	)
Balance, June 30, 2023	$	448,603

Consideration from the Company's stream agreement is considered variable. Gold and silver stream revenue can be subject to cumulative adjustments when the number of ounces to be delivered under the contract changes. As a result of changes in the Company's mineral reserve and resource estimate in the first quarter of 2023 the amortization rate by which deferred revenue is drawn down into income was adjusted and, as required, a current period variable adjustment was made for all prior period stream revenues since the stream agreement inception date. This variable consideration adjustment resulted in an increase in revenue of $4,885 and a decrease of finance expense of $96 for the six months ended June 30, 2023 (December 31, 2022 - increase in revenue of $959 and a decrease of finance expense of $940).

1 Relates primarily to restructuring costs and other non-capital provisions.

DRO are remeasured at each reporting date to reflect changes in discount rates, exchange rates, and timing and extent of cash outflows which can significantly affect the liabilities. This provision has been recorded based on estimates and assumptions that management believes are reasonable; however, actual decommissioning and restoration costs may differ from expectations.

During the six months ended June 30, 2023, the Company recorded a non-cash gain of $12,932 in the condensed consolidated interim income statements mainly related to a revaluation adjustment to the Flin Flon operation's environmental reclamation provision. The first half of 2023 was impacted by a decrease in implied inflation rates, partially offset by decreases in long term, risk-free discount rates based on changes in Canadian bond yields. Typically, an operating location will reflect any revaluation adjustments to the environmental reclamation provision against its reclamation assets. However, as the Flin Flon operations closed in June 2022, the corresponding Flin Flon assets have been fully depreciated and cannot be reduced below residual value resulting in the remaining impact being recorded as a gain in the condensed consolidated interim income statements.

As at June 30, 2023, decommissioning, restoration and similar liabilities have been discounted to their present value at rates ranging from 3.12% to 5.31% per annum (December 31, 2022 - 3.26% to 4.75%), using pre-tax, risk-free interest rates that reflect the estimated maturity of each specific liability.

During the second quarter of 2022, the Company recorded a non-cash gain of $140,533 in the condensed consolidated interim income statements mainly related to a revaluation adjustment to the Flin Flon operation's environmental reclamation provision. The first half of 2022 revaluation was substantially impacted by an increase in long term, risk-free discount rates based on changes in Canadian bond yields.

Diluted weighted average common shares outstanding	272,228,447	262,250,995	267,157,797	262,257,603

For periods where Hudbay records a loss, Hudbay calculates diluted loss per share using the basic weighted average number of shares. If the diluted weighted average number of shares were used, the result would be a reduction in the loss, which would be anti-dilutive. For the three and six months ended June 30, 2023, Hudbay calculated diluted loss per share using 272,228,447 and 267,157,797 respectively (three and six months ended June 30, 2022 - 262,250,995 and 262,257,603).

For the three and six months ended June 30, 2023, the determination of the diluted weighted-average number of common shares excludes the impact of 257,941 and 274,398 weighted-average stock options outstanding that were anti-dilutive as the Company recorded a loss in the financial period.

¹ Cash and cash equivalents, reclamation bonds, restricted cash, trade and other receivables and trade and other payables are recorded at carrying value, which approximates fair value due to their short-term nature and generally negligible credit losses.

² Excludes tax and other statutory amounts.

³ Trade and other receivables contain receivables including provisionally priced receivables classified as FVTPL and various other items at amortized cost. The fair value of provisionally priced receivables is determined using forward metals prices which is a level 2 valuation method.

⁴ Derivatives are carried at their fair value, which is determined based on internal valuation models that reflect observable forward market commodity prices, currency exchange rates, and discount factors based on market US dollar interest rates adjusted for credit risk.

⁵ All investments are carried at their fair value, which is determined using quoted market bid prices in active markets for listed shares.

⁶ These financial liabilities relate to agreements with communities near the Constancia project in Peru (note 13). Fair values have been determined using a discounted cash flow analysis based on expected cash flows and a credit adjusted discount rate.

⁷ Fair value of the senior unsecured notes (note 16) has been determined using the quoted market price at period end.

⁸ Discounted value based on a risk adjusted discount rate.

⁹ The gold prepayment liability (note 14) is designated as fair value through profit or loss under the fair value option. Gains and losses related to the Company's own credit risk have been recorded at fair value through other comprehensive income. The fair value adjustment recorded in other comprehensive income for the six months ended June 30, 2023 was a loss of $188 (year ended December 31, 2022 was a gain of $512).

¹⁰ Discounted value based on a market rate at inception of the applicable Wheaton contract for carrying value (note 17) and current market rate at period end for fair value.

¹¹ Fair value of the bonds has been determined using the Hull-White model given the debt has a call feature.

¹² Fair value of the senior secured revolving credit facility is equal to its carrying value as the drawn interest rate under the facility is comparable to current market rates.

Fair value hierarchy

The table below provides an analysis by valuation method of financial instruments that are measured at fair value subsequent to recognition as well as financial instruments not measured at fair value but for which a fair value is disclosed. Levels 1 to 3 are defined based on the degree to which fair value inputs are observable and have a significant effect on the recorded fair value, as follows:

-	Level 1:	Quoted prices in active markets for identical assets or liabilities;
-	Level 2:	Valuation techniques use significant observable inputs, either directly or indirectly, or valuations are based on quoted prices for similar instruments; and,
-	Level 3:	Valuation techniques use significant inputs that are not based on observable market data.

(in thousands of US dollars, except where otherwise noted)
For the three and six months ended June 30, 2023 and 2022

The Company's policy is to recognize transfers into and transfers out of fair value hierarchy levels as of the date of the event or change in circumstances that caused the transfer. During the six months ended June 30, 2023 and year ended December 31, 2022, Hudbay did not make any such transfers.

Valuation techniques used for instruments categorized in Levels 2 and 3 are consistent with the year ended December 31, 2022, except as noted below.

The following additional valuation techniques are used for instruments categorized in Level 3:

-Copper Mountain Bonds (Level 3) - This liability has been fair valued using the Hull-White model given the debt has a call option feature.

-Senior secured revolving credit facilities (Level 3) - This liability has been fair valued using an applicable credit adjusted discount rate.

(b)Derivatives and hedging:

Copper fixed for floating swaps

Hudbay enters into copper fixed for floating swaps in order to manage the risk associated with provisional pricing terms in copper concentrate sales agreements. As at June 30, 2023, Hudbay had 54.0 million pounds of net copper swaps outstanding at an effective average price of $3.93/lb and settling from July to September 2023. As at December 31, 2022, Hudbay had 89.7 million pounds of net copper swaps outstanding at an effective average price of $3.61/lb and settling from January to May 2023. The aggregate fair value of the transactions at June 30, 2023 was an asset of $8,433 (December 31, 2022 - a liability position of $17,269).

Zinc fixed for floating swaps

Hudbay enters into zinc fixed for floating swaps in order to manage the risk associated with provisional pricing terms in zinc concentrate sales agreements. As at June 30, 2023, Hudbay had 18.0 million pounds of net zinc swaps outstanding at an effective average price of $1.16/lb and settling from July to September 2023. As at December 31, 2022, Hudbay had 17.5 million pounds of net zinc swaps outstanding at an effective average price of $1.32/lb and settling from January to March 2023. The aggregate fair value of the transactions at June 30, 2023 was an asset of $1,383 (December 31, 2022 - a liability position of $149).

Copper costless collars

Hudbay entered into a zero-cost collar program in April 2023 for approximately 10% of copper production expected in the second half of 2023. The program entails a hedge for 15.9 million pounds of copper for six months starting in July 2023 and establishes a floor price of $3.95 per pound and a cap price of $4.28 per pound. Gains and losses resulting from the settlement of these derivatives are recorded directly to revenue, as the forward sales contracts do not qualify for hedge accounting, and the associated cash flows are classified in operating activities. As at June 30, 2023, 15.9 million pounds of copper collars were unsettled (December 31, 2022 - nil). The aggregate fair value of the position at June 30, 2023 was an asset of $4,477 (December 31, 2022 - nil).

Transactions involving derivatives are with large multi-national financial institutions that Hudbay believes to be credit worthy.

(c)Provisionally priced receivables

Changes in fair value of provisionally priced receivables

Hudbay records changes in fair value of provisionally priced receivables related to provisional pricing in concentrate purchase, concentrate sale and certain other sale contracts. Under the terms of these contracts, prices are subject to final adjustment at the end of a future period after title transfers based on quoted market prices during the quotation period specified in the contract. The period between provisional pricing and final pricing is typically up to three months.

Changes in fair value of provisionally priced receivables are presented in trade and other receivables when they relate to sales contracts and in trade and other payables when they relate to purchase contracts. At each reporting date, provisionally priced metals are marked-to-market based on the forward market price for the quotation period stipulated in the contract, with changes in fair value recognized in revenue for sales contracts and in inventory or cost of sales for purchase concentrate contracts. Cash flows related to changes in fair value of provisionally priced receivables are classified in operating activities.

As at June 30, 2023 and December 31, 2022, Hudbay's net position consisted of contracts awaiting final pricing are as indicated below:

Metal in		Sales awaiting final pricing		Average YTD price ($/unit)
concentrate	Unit	Jun. 30, 2023	Dec. 31, 2022	Jun. 30, 2023	Dec. 31, 2022

Zinc	pounds (in thousands)	18,917	18,145	1.08	1.35

The aggregate fair value of provisionally priced receivables within the copper and zinc concentrate at June 30, 2023, was a liability position of $9,236(December 31, 2022 - an asset position of $20,285).

(d)Other financial liabilities

25.Segmented information

As at June 30, 2023, Hudbay has five reportable segments identified by the individual mining operations of Manitoba, Copper Mountain (British Columbia), Peru, as well as the Copper World project (Arizona) and Corporate and other activities. The acquisition of Copper Mountain was completed on June 20, 2023. However, Hudbay's second quarter 2023 loss was not materially affected by the acquisition as Copper Mountain had no revenues or corresponding cost of sales recorded during the 10 day stub period from the date of acquisition to the end of the second quarter. No results for the British Columbia segment are reflected in the prior period comparative figures. Corporate and other activities include the Company's exploration activities in Chile, Canada and the State of Nevada. These exploration entities are not individually significant, as they do not meet the minimum quantitative thresholds for standalone segment disclosure. Corporate and other activities are not considered a segment and are included as a reconciliation to total consolidated results.

26.Events after the reporting period

Acquisition of Rockcliff Metals Corp.

On June 19, 2023, Hudbay and Rockcliff Metals Corp. ("Rockcliff") entered into a definitive agreement pursuant to which Hudbay has agreed to acquire 100% of the issued and outstanding common shares of Rockcliff (the "Proposed Transaction").

Under the terms of the Proposed Transaction, Rockcliff shareholders will receive 0.006776 of a Hudbay common share for each Rockcliff common share held. The estimated value of the transaction excluding Rockcliff's cash, is approximately $13 million.

The Proposed Transaction will be implemented by way of a court-approved plan of arrangement under the Business Corporations Act (Ontario) and, in addition to court approval, is subject to customary closing conditions, including approval by Rockcliff shareholders and approval under the Competition Act (Canada). The Proposed Transaction is expected to close in the third quarter of 2023.

Copper Mountain Bonds

The Bonds, which were assumed as part of the Copper Mountain acquisition, provided the bondholders with the right to put all or part of the principal amount of the outstanding Bonds to Copper Mountain at a price equal to 101%, plus accrued interest, following a change of control event. With the acquisition of Copper Mountain on June 20, 2023, the change of control event was triggered and $83,307 of the Bonds were put to Copper Mountain on July 17, 2023. On July 19, 2023 Copper Mountain purchased $83,307 at 101% plus accrued interest applicable under these bonds for a total payment of $86,084.
