In this AIF, except as otherwise required by the context, references to Equinox Gold, the Company, our and we mean Equinox Gold Corp. and its subsidiaries, collectively. Date of Information This AIF is dated February 22, 2024. Unless otherwise stated, all information in this AIF is provided as of December 31, 2023.

All financial information presented in this AIF was prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board. Non-IFRS and Other Financial Measures This AIF includes certain non-IFRS measures, namely: cash costs; cash costs per ounce (oz) sold; all-in sustaining costs (AISC); AISC per oz sold; and sustaining capital expenditures.

Annual Information Form - 10 - GENERAL DEVELOPMENT OF THE BUSINESS Business of Equinox Gold Equinox Gold is a growth-focused mining company delivering on its strategy of creating the Premier Americas Gold Producer. Equinox Gold was created with the strategic vision of building a company that will responsibly and safely produce more than one million ounces of gold annually, bring long-term social and economic benefits to its host communities, create a safe and rewarding workplace for its employees and contractors, and provide above-average investment returns to its shareholders. The Company is principally engaged in the operation, development and exploration of gold projects and has quickly grown from a single-asset developer to a multi-asset gold producer with seven operating gold mines as at the date of this AIF. To achieve its growth objectives, Equinox Gold intends to expand production from its current asset base through exploration and development and look for opportunities to acquire other companies, producing mines and/or development projects that fit the Company’s portfolio and strategy. Equinox Gold’s material producing assets are Mesquite and Castle Mountain in California State, USA, Los Filos in Guerrero State, Mexico, Aurizona in Maranhão State, Brazil, and Fazenda and Santa Luz in Bahia State, Brazil. Greenstone in Ontario, Canada is in construction and is also a material asset. Together Equinox Gold’s material producing assets and Greenstone are referred to in this AIF as the Equinox Gold Projects. The Company holds a 60% interest in Greenstone, with the remaining 40% held by an affiliate of Orion Mine Finance Group (Orion). The other Equinox Gold Projects are all 100% owned by the Company. Equinox Gold also has 100% ownership of the RDM Mine (RDM) in Minas Gerais State, Brazil. RDM is a producing mine but is not considered a material project for Equinox Gold. Equinox Gold produced 564,458 ounces of gold in 2023 at total cash costs of $1,350 per ounce and AISC of $1,612 per ounce.1 The Company released 2024 production guidance on February 21, 2024, estimating production of 660,000 to 750,000 ounces of gold for the year at cash costs of $1,340 to $1,445 per ounce and AISC of $1,630 to $1,740 per ounce.1 Guidance is intended to provide baseline estimates from which investors could assess the Company’s expectations for its production and operating costs for the year. The Company may revise its guidance during the year to reflect changes to expected results. The Company is commissioning Greenstone and advancing expansion projects at Castle Mountain, Aurizona and Los Filos. With the incremental production growth anticipated from these development and expansion projects, the Company believes it has the assets in place to achieve its objective of producing more than one million ounces of gold per year. The Company may still consider opportunities to acquire other companies, producing mines and/or development projects that fit the Company’s portfolio and strategy. 1 Cash costs per ounce and AISC per ounce sold are non-IFRS measures. See Non-IFRS Measures.

The Orion Transaction was subject to closing of the Premier Transaction. On completion of both the Orion Transaction and the Premier Transaction on April 7, 2021, Equinox Gold owned 60% of Greenstone. Greenstone has been advanced in a 60/40 partnership between Equinox Gold and Orion through their respective ownership of Greenstone Gold Mine GP Inc. (GGM) which manages Greenstone. On March 3, 2021, the company announced that it produced 477,186 ounces of gold in 2020 at cash costs of $847 per ounce and AISC of $1,027 per ounce of gold sold.1 On March 17, 2021, the Company completed the first tranche of a private placement of subscription receipts at a price of C$10.00 per subscription receipt. The second tranche of the Private Placement closed in April 2021. The total proceeds to the Company from the issuance of the subscription receipts was C$75 million (Private Placement). Each subscription receipt entitled the holder to receive one common share of Equinox Gold. Certain of the Company’s executives and directors subscribed for C$40.4 million in subscription receipts which are related party transactions. No finders’ fees or commissions were paid in connection with the Private Placement. The proceeds of the Private Placement were for general working capital purposes.

(Solaris) to Augusta Investments Inc. and a strategic shareholder for gross proceeds of approximately C$82.5 million. 1 Cash costs per ounce and AISC per ounce sold are non-IFRS measures. See Non-IFRS Measures.

Annual Information Form - 12 - In addition, the Company granted the buyers warrants to purchase an additional five million Solaris shares from the Company for a period of 12 months at C$10.00 per share (the Solaris Warrants). In March 2021, a historic rain event caused widespread flooding in the Aurizona region and a freshwater pond on the Aurizona site overflowed. The tailings facility and other infrastructure at the Aurizona site remained intact and operational. The Company subsequently received several fines from the local state government for environmental infractions related to turbidity in the local water supply at Aurizona following the rain event. In addition, a public civil action has been filed against the Company by the State prosecutor claiming various damages as a result of the rain event. The Company considers the fines and public civil action to be without merit. On April 7, 2021, the Company completed the Premier Transaction, adding Premier’s interest in the Greenstone project, Mercedes and the Hasaga and Rahill-Bonanza exploration properties to the Company’s existing portfolio of gold assets. The spin-out of i-80 Gold was completed at the same time and the Company became a 30% shareholder of i-80 Gold. The Private Placement was completed contemporaneously with the Premier Transaction. A total of 54,873,723 Common Shares were issued on completion of the Premier Transaction and the Private Placement. On April 19, 2021, the Company announced the sale of its Pilar Mine in Brazil to Pilar Gold Inc. (PGI) for consideration of: • $38 million in cash, payable: o $10.5 million on closing, which has been received; o $10 million payable on or before May 31, 2021, which has been received; and o $17.5 million payable on or before July 31, 2021 (Third Tranche) • 9.9% equity interest in PGI; and • 1% net smelter returns royalty on production from the Pilar Mine. The payment date for the Third Tranche was subsequently extended by the Company to November 30, 2023. On April 28, 2021, the Company completed the previously announced sale of a portion of its shareholdings in Solaris and the associated grant of the Solaris Warrants. At the Company’s Annual General Meeting on May 5, 2021, shareholders approved all of the matters voted on at the meeting and appointed Ross Beaty, Lenard Boggio, Maryse Bélanger, Tim Breen, Gordon Campbell, Wesley Clark, Dr. Sally Eyre, Marshall Koval and Christian Milau as directors. On June 22, 2021, the Company announced the suspension of mining and development activities at Los Filos due to blockades by a group of unionized employees and members from one of the three communities from which the mine draws its workforce. The union blockade was removed in July, access to the mine was restored and the Company resumed operations in parts of the mine. The community blockade was subsequently removed in early August and the Company resumed regular operations in all areas of the mine. On August 4, 2021, the Company updated production and cost guidance to reflect solid performance at the Brazil sites and the disruption to mining activities at Los Filos. Updated guidance estimated 560,000 to 625,000 ounces of gold production at cash costs of $1,025 to $1,075 per ounce and AISC of $1,300 to $1,375 per ounce of gold sold.1 The Company filed updated technical reports for Fazenda and RDM on October 22, 2021, and for Aurizona on November 4, 2021. Mineral Reserve and Mineral Resource estimates for each of the material properties is outlined in the section entitled Mineral Projects. 1 Cash costs per ounce and AISC per ounce sold are non-IFRS measures. See Non-IFRS Measures.

Annual Information Form - 13 - On October 27, 2021, the Company announced ground-breaking for full-scale construction at Greenstone with an approved construction budget of $1.23 billion. The project timeline contemplated approximately two years of construction and six months of commissioning, with first gold pour targeted for the first half of 2024. On December 17, 2021, the Company announced that it had entered into a definitive agreement to sell the Mercedes Mine (Mercedes) to Bear Creek Mining Limited (Bear Creek) for aggregate consideration of: • $100 million in cash, payable as: o $75 million on closing of the transaction; and o $25 million payable within six months of closing the transaction. • 24,730,000 common shares of Bear Creek; and a • 2% net smelter return payable on production from Mercedes. On December 30, 2021, the Company announced the retirement of Mubadala’s representative Mr. Tim Breen from the Company’s Board effective December 31, 2021 and the appointment of Mr. François Bellemare as his replacement effective January 1, 2022. Year Ended December 31, 2022 On February 24, 2022, the Company announced that it produced 602,110 ounces of gold in 2021 at cash costs of $1,087 per ounce and AISC of $1,350 per ounce of gold sold.1 On March 30, 2022, the Company poured first gold at Santa Luz. On April 21, 2022, the Company completed the sale of Mercedes to Bear Creek. On May 26, 2022, the Company and Sandstorm Gold Ltd. announced the creation of Sandbox. Pursuant to the transaction, Sandbox acquired a portfolio of royalties and other assets from the Company for consideration of $28.4 million common shares of Sandbox, representing a 30% basic interest in Sandbox. The transaction closed on June 28, 2022. On July 28, 2022, the Company amended its revolving credit facility to, among other things, increase the maximum amount available under the revolving facility from $400 million to $700 million, add an additional $100 million uncommitted accordion feature, reduce pricing for advances by 0.25% – 0.50% depending on leverage ratios and extend the maturity date to July 28, 2026 (with the ability to request additional one-year extensions). On August 3, 2022, the Company updated guidance to reflect a disruption to mining and operations at RDM, a longer- than-expected ramp up at Santa Luz that prolonged pre-commercial production, and further inflation of approximately 6% on a consolidated basis. Updated production guidance was estimated at 550,000 to 615,000 ounces of gold with cash costs of $1,200 to $1,250 per ounce and AISC of $1,470 to $1,530 per ounce of gold sold.1 On August 3, 2022, the Company announced the resignation of Christian Milau as Chief Executive Officer and Director, and that the Company’s President, Greg Smith, would succeed Mr. Milau. Mr. Smith assumed the role of Chief Executive Officer and was appointed a Director on September 1, 2022. 1 Cash costs per ounce and AISC per ounce sold are non-IFRS measures. See Non-IFRS Measures.

Annual Information Form - 14 - On September 8, 2022, the Company announced the suspension of mining and development activities at Los Filos due to a blockade by members of one of the three communities from which the mine draws much of its workforce. Following a meeting with community leaders the blockade was removed and the mine resumed operations on September 10, 2022. On October 4, 2022, the Company announced that Santa Luz achieved commercial production effective October 1, 2022. On October 19, 2022, the Company announced the results of an updated feasibility study for the Los Filos expansion, including a 44% increase in Los Filos Mineral Reserves. The feasibility study contemplates continued development of the Bermejal underground deposit and construction of a 10,000 t/d carbon-in-leach (CIL) processing plant that would operate concurrently with existing heap leach facilities. While the economic and production estimates outlined in the feasibility study are predicated on construction of the CIL plant commencing in 2023, Equinox Gold has not made a decision to proceed with the expansion at this time. The Company filed a technical report relating to the Los Filos feasibility study on October 4, 2022. On November 2, 2022, the Company reported its financial and operations results for the third quarter of 2022. The Company announced that it expected full-year production to be approximately 540,000 ounces of gold and AISC to exceed the upper end of guidance of $1,530 per ounce produced by approximately five percent. A material change report regarding the reporting of such financial and operational results was filed by the Company on November 8, 2022. On November 21, 2022, the Company announced that it had entered into an equity distribution agreement providing for an at-the market equity offering program (ATM) with BMO Capital Markets and National Bank Financial and their respective affiliates (collectively, the Agents). The ATM allows the Company, through the Agents, to offer and sell from time to time in Canada and the United States through the facilities of the TSX and NYSE, such number of common shares as would have an aggregate offering price of up to US$100 million. The ATM is effective until December 21, 2024, unless terminated earlier. In addition, the Company announced filing of a registration statement including a base shelf prospectus, and a shelf prospectus supplement for the ATM. On December 6, 2022, the Company announced that it had sold an aggregate of 11,000,000 common shares of Solaris in the ordinary course for investment purposes through the facilities of the TSX through block trades for aggregate gross proceeds of C$70.4 million. As a result of the transaction, Equinox Gold’s ownership in Solaris decreased to less than 10% of the issued and outstanding common shares of Solaris and Equinox Gold ceased to be a “reporting insider” of Solaris, as defined in National Instrument 55-104 – Insider Reporting Requirements. Year Ended December 31, 2023 On February 7, 2023, the Company released its inaugural Climate Action Report and announced its target to achieve a 25% reduction in GHG emissions by 2030 compared to “business-as-usual” emissions if no intervention measures were taken. On February 21, 2023, the Company announced that it produced 532,319 ounces of gold in 2022 at cash costs of $1,328 per ounce and AISC of $1,622 per ounce of gold sold.1 1 Cash costs per ounce and AISC per ounce sold are non-IFRS measures. See Non-IFRS Measures.

Annual Information Form - 15 - On March 7, 2023, the Company announced that it had entered into an agreement to sell 11.6 million units of i-80 Gold at a price of C$2.76 per unit for gross proceeds of C$23.6 million. Each unit consisted of one common share of i-80 Gold and one-half of one common share purchase warrant of i-80 Gold, with each whole warrant exercisable to purchase one common share of i-80 Gold at a price of C$3.45 per share for a period of 12 months following closing of the transaction on March 31, 2023. In the event all warrants are exercised, Equinox Gold would sell a total of 17.4 million shares of i-80 Gold for total gross proceeds of C$52,026,000. On March 24, 2023, the Company entered into a gold sale prepay arrangement with a syndicate of its existing lenders whereby the Company received net proceeds of $139.5 million in exchange for delivering 3,605 ounces of gold per month from October 2024 through July 2026 (Delivery Period) for a total of 79,310 ounces. On June 23, 2023, the Company entered into an additional gold sale prepay transaction with an existing lender whereby the Company received an upfront cash prepayment of $9.9 million in exchange for delivering to the lender 263.5 ounces of gold per month during the Delivery Period for a total of 5,797 ounces. These transactions are referred to collectively as the Gold Prepay Transactions. Gold deliveries can be settled by production from any of the Company’s operating mines and the Gold Prepay Transactions can be settled prior to maturity through accelerated delivery of the remaining deliverable gold ounces. On September 21, 2023, the Company closed a bought deal offering of 4.75% unsecured convertible senior notes (2023 Convertible Notes) in an aggregate principal amount of $150 million, plus exercise of the full amount of the option to purchase an additional $22.5 million aggregate principal amount of the 2023 Convertible Notes, for gross proceeds of $172.5 million. The conversion rate for the 2023 Convertible Notes is 158.7302 Common Shares per $1,000 principal amount of the 2023 Convertible Notes, equivalent to a conversion price of $6.30 per Common Share. On October 31, 2023, the Company closed a gold purchase agreement with Sandbox and Regal Partners Royalties A PTY Limited (Regal and together with Sandbox, the Purchasers). Under the agreement, the Company received a payment of $75 million in exchange for monthly deliveries to the Purchasers equal to the greater of: a) 500 gold ounces and b) gold ounces equal to 1.8% of the monthly gold production from Greenstone (100% basis). Gold deliveries can be from production from any of the Company’s operating mines. Gold deliveries started in November 2023 and will continue until a total of 90,000 ounces have been delivered. The Purchasers will make ongoing cash payments equal to 20% of the spot gold price for each gold ounce delivered. The Company may buy down up to 75% of the delivery obligation at the then current spot gold price, subject to adjustment for the ongoing payment and a minimum price per ounce of $2,000. On November 20, 2023, the Company announced that the Greenstone Project was 96% complete, commissioning activities were underway, and the project was on budget and on schedule to pour gold in the first half of 2024. Recent Developments On February 21, 2024, the Company announced that it produced 564,457 ounces of gold in 2023 at cash costs of $1,350 per ounce and AISC of $1,612 per ounce of gold sold.1 On February 21, 2024, the Company issued production guidance of 660,000 to 750,000 ounces of gold for 2024 at cash costs of $1,340 to $1,445 per ounce and AISC of $1,630 to $1,740 per ounce.1 1 Cash costs per ounce and AISC per ounce sold are non-IFRS measures.

Annual Information Form - 16 - DESCRIPTION OF THE BUSINESS Equinox Gold is a growth-focused mining company delivering on its strategy of creating a diversified, Americas- focused gold company that will responsibly and safely produce more than one million ounces of gold annually. The Company significantly increased both its scale and asset diversification in March 2020 through completion of the Leagold Transaction, which brought four producing mines, a development project and an expansion project to the Company’s portfolio. The Company continued that growth in 2021 with completion of the Premier Transaction, adding a 60% interest in a development project, a producing mine and exploration properties to the Company’s existing portfolio of gold assets. Since starting the Company, Equinox Gold has constructed and achieved production at three mines (Aurizona, Castle Mountain and Santa Luz), spun-out non-core assets into two new companies (Solaris and Sandbox) and sold two of its smaller mines (Mercedes and Pilar). During 2023 the Company advanced the construction of Greenstone, which is on track to pour gold in the first half of 2024. For continued growth, the Company intends to expand and extend production from its current asset base through exploration and development and will look for opportunities to acquire other companies, producing mines and/or development projects that fit the Company’s portfolio and strategy. Equinox Gold’s operating mines and development projects are as follows: Name of Mineral Property Ownership Location Status Mesquite Gold Mine 100% California State, USA Producing Castle Mountain Gold Mine 100% California State, USA Phase 1 Producing Permitting a Phase 2 expansion Los Filos Mine Complex 100% Guerrero State, Mexico Producing Aurizona Gold Mine 100% Maranhão State, Brazil Producing Advancing study for potential expansion Fazenda Gold Mine 100% Bahia State, Brazil Producing Santa Luz Gold Mine 100% Bahia State, Brazil Producing RDM Gold Mine 100% Mina Gerais State, Brazil Producing Greenstone Project 60% Ontario, Canada In construction Equinox Gold’s material assets are Mesquite, Castle Mountain, Los Filos, Aurizona, Fazenda, Santa Luz and Greenstone. Principal Products Equinox Gold’s principal product is gold doré. The principal buyers of gold doré produced from Equinox Gold’s mines, once refined, are international bullion banks, traders and refiners themselves. However, there is a worldwide market for gold into which Equinox Gold could sell its gold and, as a result, Equinox Gold is not dependent on a particular purchaser with regard to the sale of gold, silver or other metals which it produces. Community Engagement and Investment Equinox Gold understands that local communities are important stakeholders in our business activities. We seek to understand and appropriately address their interests and concerns. We believe that mining projects can provide significant economic benefits and social development opportunities for local communities that can endure well beyond the life of a project. Equinox Gold offers training programs and is committed to hiring locally. The Company also supports development initiatives that meet the needs and priorities of local communities with the objective of leaving a legacy of improved infrastructure, skills development and more sustainable communities.

Annual Information Form - 17 - Equinox Gold engages in early, frequent and transparent dialogue with stakeholders as a means to build trust and provide a space for collaboration and long-term commitment. The Company maintains formal systems to identify stakeholders and communities of interest and strives to maintain strong local relationships. At all of the Company’s mine sites, dedicated community liaisons meet regularly with host communities to discuss activities, report on environmental performance and discuss concerns. The Company seeks local feedback, particularly where concerns have been raised and collaborative solutions can be implemented. Health & Safety The health and safety of the Company’s workforce is a top priority for Equinox Gold. By adopting a strong risk management approach, Equinox Gold engages with and trains our workforce to recognize, understand and mitigate hazards of the workplace to prevent incidents and injuries. We comply with all relevant local, state, and federal laws and have implemented best practices and industry standards. During 2023, Equinox Gold completed 20.3 million work hours with seven lost-time incidents across its sites resulting in a lost time injury frequency rate (LTIFR) of 0.34 per million hours worked compared to the target of 0.63 for 2023. Four of the Company’s sites had no lost-time incidents during 2023. The Company’s total recordable injury frequency rate (TRIFR), which is a measure of all injuries that require the attention of medically trained personnel, was 1.47 per million hours worked compared to the target of 3.25 for 2023, a 31% improvement over the Company’s TRIFR of 2.12 for 2022. After more than five years with no fatalities, Equinox Gold had a fatality during 2023 at its Santa Luz mine; no other personnel were injured. A site-wide safety stop took place and Santa Luz held three full days of safety refresher training for its workforce before restarting operations. An investigation to determine the cause of the incident was undertaken and the learnings were shared across the organization. Environment Environmental stewardship is fundamental to Equinox Gold’s operations. We aim to minimize or mitigate the potential effects of our operations on regional flora, fauna, water quality and air quality. Understanding the components of the ecosystem and the potential impacts of mining activities allows us to plan appropriately and adopt mitigation strategies to eliminate or reduce impacts to an acceptable level. During 2023, Equinox Gold achieved a significant environmental incident frequency rate (SEIFR) of 0.29 per million hours worked, using the Company’s internal environmental reporting standards, compared to the target of 1.4 for 2023, which was a 54% improvement over the Company’s SEIFR of 0.63 for 2022. Equinox Gold operates in Canada, Mexico, Brazil, and the United States and is subject to national and local laws and regulations in each relevant jurisdiction. All aspects of Equinox Gold’s operations, development activities and exploration programs are subject to environmental regulations and generally require approval by appropriate regulatory authorities prior to commencement. Specific statutory and regulatory requirements and standards must be met throughout the mine cycle, including but not isolated to standards related to air quality, water quality, fisheries and wildlife protection, chemical use, waste disposal, noise, geotechnical stability, geochemistry and land use. When operations cease, the Company is also required to return the land as close as possible to its original state. Details and quantification of Equinox Gold’s reclamation and closure costs obligations as at December 31, 2023, are set out in the Company’s annual financial statements for the year ended December 31, 2023.

Annual Information Form - 18 - Employees and Contractors At the end of the most recently completed financial year, Equinox Gold had a total of 3,692 employees and 4,384 contractors (including employees and contractors of GGM on a 100% basis). No management functions of Equinox Gold are performed to any substantial degree by a person other than the directors or executive officers of Equinox Gold. Equinox Gold is committed to hiring locally and the majority of employees and contractors at each of its operations come from local communities The Company has engaged external advisers to develop an enterprise-wide diversity strategy. As part of this process human resources leaders at each of Equinox Gold's sites have participated in workshops to better understand their site-specific challenges and initiatives already in place. Specialized Skill and Knowledge Many aspects of Equinox Gold’s business require specialized skills and knowledge, such as expertise in the areas of mine operations, mine construction, permitting, geology, drilling, implementation of exploration programs, logistical planning, accounting, communications and local laws. Equinox Gold retains executive officers and consultants with experience in mining, metallurgy, geology, exploration and development in Canada, Mexico, Brazil, and the United States, as well as executive officers and consultants with relevant accounting, communications and legal experience. Competitive Conditions The mineral exploration and mining industry is competitive, and Equinox Gold is required to compete for the acquisition of mineral permits, claims, leases and other mineral interests for operations, exploration, and development projects. As a result of this competition, Equinox Gold may not be able to acquire or retain prospective properties in the future on terms it considers acceptable. The ability of Equinox Gold to acquire and retain mineral properties in the future will depend on its ability to successfully operate and develop its existing properties and also on its ability to fund further exploration and development activities. Equinox Gold also competes with other mining companies for investment capital with which to fund such projects, and for the recruitment and retention of qualified personnel. Components The raw materials and support services that Equinox Gold requires to carry on its business are available through normal supply or business contracting channels in Canada, Mexico, Brazil, and the United States. Increased demands by other mineral exploration, development and operating companies, inflationary pressures, or disruptions to supply chains due to events like pandemics, and other global events can make it more difficult to procure certain supplies and services. Cycles The mining business, and particularly precious metals production, is subject to metal price cycles. The marketability of minerals and mineral concentrates is also affected by worldwide economic cycles. Foreign Operations Equinox Gold faces certain risks as a Canadian company operating in Mexico, Brazil, and the United States. Any changes in regulations or shifts in political attitudes are beyond the control of Equinox Gold and may adversely affect its business. Equinox Gold may be affected in varying degrees by factors such as government regulations (or changes thereto) with respect to restrictions on mining, export controls, income taxes, expropriation of property, repatriation of profits, environmental legislation, tariffs, land use, water use, land claims of local people, changes in foreign exchange, mine safety regulations, labour laws, corruption, political unrest, timely reimbursement by the government of refundable value added taxes and refundable income taxes, uncertainty with respect to the rule of law and the integrity of court systems, and security issues. The effect of these factors cannot be accurately predicted.

Annual Information Form - 22 - Mesquite Mine Mesquite is a run-of-mine (ROM) heap leach gold mine located in California, USA. Mesquite has produced more than 5 million ounces of gold since commencing operations in 1986. Equinox Gold acquired the project from New Gold on October 30, 2018. Unless otherwise indicated, the information that follows relating to Mesquite is based on, derived substantially from, and in some instances is a direct extract from, the Mesquite Technical Report. Technical information disclosed since the effective date of the Mesquite Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151. The information below is based on assumptions, qualifications and procedures that are set out only in the Mesquite Technical Report and reference should be made to the full text of the Mesquite Technical Report which Equinox Gold has filed under its SEDAR+ profile at www.sedarplus.ca, its EDGAR profile at www.sec.gov/EDGAR and which is also available on Equinox Gold’s website at www.equinoxgold.com. Project Description, Location and Access The Mesquite Mine is located approximately 35 miles to the east of the town of Brawley, California, and about 52 miles northwest of the city of Yuma, Arizona. The property is at Latitude 33° 03’ North and Longitude 114° 59’ West. Access to the property is from California State Highway 78 and then north along a paved private road into the Mesquite Mine. The property is approximately 24 miles north of the border with Mexico and 16 miles west of the border with the State of Arizona. Equinox Gold completed the acquisition of Western Mesquite Mines, Inc. (WMMI), from New Gold, on October 30, 2018. WMMI, Equinox Gold’s wholly-owned subsidiary, holds a 100% interest in the property and operates the mine. The major assets and facilities of WMMI are an open pit gold heap leach mining operation with a carbon-in-column (CIC) processing circuit. A smelting furnace, assay and metallurgical laboratories, administration building, truck shop facility, and other required infrastructure are also located on the mine site. Mineral Tenure The mineral rights at Mesquite consist of 265 unpatented and 53 patented mining lode claims, 97 unpatented and 122 patented mill site claims, 658 acres of California State leased land, and a lease of a portion of the 4,275 acres of adjacent private land owned by the Los Angeles County Sanitation District (LACSD). All the aforementioned properties are controlled by WMMI and are collectively identified as the Mesquite Plan of Operations Area. The claims located on federally owned lands are administered by the Bureau of Land Management (BLM). Patented mining lode claims and patented mill site claims on U.S. Federal Land represent a secure title to the land. Unpatented mining and mill site claims do not have a termination date as long as annual assessment work is maintained and the land is held for mining purposes. The Federal fee land is leased by WMMI and can also be maintained indefinitely as long as the annual maintenance fees are paid.

Annual Information Form - 23 - Surface Rights The surface ownership of patented mining claims, which are identified as Imperial County Assessor’s parcels, have all the general rights of surface ownership as fee land. WMMI also owns patented claims and mill sites south of the mine property for water supply wells. WMMI has surface operation rights within the leased parcel of the State of California Property. The lode claims and mill sites maintained by WMMI provide the general right for surface management and operations, subject to environmental permitting and other compliance activities unique to public lands. However, under California’s Environmental Quality Act (CEQA) authority, which generally mirrors the National Environmental Policy Act (NEPA) requirements the BLM is tasked to administer, there is little practical difference in operations and reclamation requirements regardless of whether the land is public or private. The LACSD is constructing a landfill facility adjacent to, and overlying portions of, the existing Mesquite property. The landfill project will be located on private land owned by LACSD. Under the agreement, WMMI has retained the right to explore, mine, extract, process, market and sell ore, and otherwise conduct mining and processing activities, anywhere within the Mesquite property for an initial period through 2024 with automatic extensions until 2078. LACSD has the right to utilize portions of the overburden stockpiles and spent ore from the leach pads for use as daily cover for the landfill, as well as for construction materials for general purposes as well as liner design. This material will be jointly used by both LACSD and WMMI, but WMMI will have priority. Royalties Most of the Mineral Reserves planned for future mining at Mesquite will be subject to a 0.5% to 2% production royalty due to Franco-Nevada Corporation and a 2% production royalty due to Glamis Associates, depending on the claim group. Claims jointly owned by Franco-Nevada Corp. and Glamis will pay a 1% royalty to Franco-Nevada and a 2% royalty to Glamis Associates. The average royalty per year is 2.6% to the combination of Franco-Nevada Corp. and Glamis Associates. WMMI also pays a 6% to 9% NSR (depending on the relevant gold price) to the California State Lands Commission (CSLC) on production from certain California State leased lands under a Mineral Extraction Lease between WMMI and the CSLC. The royalty percentages are calculated as follows: below $1,300 per troy ounce of gold, the royalty is 6%; from $1,300 to $1,800 per troy ounce of gold, the royalty is 7%; from $1,800 to $3,600 per troy ounce of gold, the royalty is 8%; and above $3,600 per troy ounce of gold, the royalty increases to a maximum of 9%. History Gold was first discovered at Mesquite by track crews building the Southern Pacific railroad around 1876. First gold production at Mesquite dates to the late 1800s and early 1900s when placer gold was recovered on a small scale. During the 1920s and 1930s, small-scale subsistence placer mining was conducted in the district. Larger placer and lode mining were reported in the area from 1937 through to the mid-1970s and a number of companies explored the area. Gold Fields Mining Corporation acquired the property in 1980, conducted exploration and development over the ensuing years and began commercial gold production at Mesquite in March 1986 as a heap leach gold operation. In 1993, Santa Fe Pacific Gold Corporation (Santa Fe) acquired Mesquite. In 1997, Santa Fe was acquired by Newmont Mining Corporation (Newmont). Newmont mined the deposit through May 2001, when there was a slope failure in one of the pits and the existing reserves at a $300 gold price were deemed uneconomic. A total of 154 million tons of material grading 0.026 ounces per ton (opt) gold had been placed on the leach pads when mining operations stopped in 2001, and gold recovery from the leach pads continued through to 2007.

Annual Information Form - 24 - Western Goldfields Inc. (WGI) acquired Mesquite from Newmont in November 2003, completed a feasibility study in 2006 and restarted operations in late 2007. Commercial production was achieved in January 2008. In June 2009, following a business combination with WGI, New Gold became the operator. Newmont’s 2% NSR royalty on the project was transferred to Franco-Nevada in 2007. Equinox Gold acquired Mesquite from New Gold in October 2018. Geological Setting, Mineralization and Deposit Types The Mesquite Mine district lies on the southwest flank of the Chocolate Mountains, in amphibolite grade metamorphic rocks of the upper plate of the Vincent-Chocolate Mountain Thrust. These upper plate rocks represent a fragment of Precambrian and Mesozoic continental crust that has an extremely complex geological history. Mesquite comprises two subparallel, Oligocene-age deposits: Big Chief – Vista (Big Chief, Cholla, Lena, Rubble Ridge, Panhandle, and Vista) and Rainbow (Cherokee, Rainbow, and East Rainbow). Gold mineralization is hosted in Mesozoic gneisses that are intruded by biotite/muscovite rich granites. The district is covered by a thin veneer (0- 300 ft.) of Tertiary and Quaternary sediments, shed from the south slope of the Chocolate Mountains. Gold mineralization is bound by post-mineral faulting related to the Neogene San Andreas fault system. Exploration Gold was first discovered at Mesquite in 1876. Exploration has been undertaken by prospectors since 1957 and by a number of mining companies since 1980. Exploration sampling, trenching, and drilling identified a number of gold bearing zones. In 1980, Gold Fields initiated a thorough exploration program that included surface sampling and geophysics and in 1981 commenced a RC drilling program. By 1993, Gold Fields had completed more than 5,000 holes totalling 2.4 million ft. There are a number of exploration targets within the footprint of the Mesquite operation boundaries. Historic waste dump material, placed during periods of lower gold price and high cut-off grade, will be drilled to assess gold grade and economic potential. RC drilling will be conducted in the dump areas in 2020 to the standard required to convert any delineated mineralized material into Mineral Resources that can be considered for conversion to Mineral Reserves. RC in-fill drilling will also be conducted in select in-pit targets to increase Mineral Resource confidence for classification and potential for conversion to Mineral Reserves. Drilling Drilling on the Mesquite property has totalled approximately 3.3 million ft. in 9,728 holes of which WMMI drilled approximately 514,955 ft. in 1,700 holes. Of the total holes drilled to date, 118 holes in the database were exploratory in nature, and tested for satellite deposits. The holes were mostly drilled vertically. In general, the disseminated mineralization is flat-lying or with a moderate 16° southwest dip and therefore the vertical drilling provides an appropriate measure of the true thickness of mineralization. Since acquiring Mesquite Equinox Gold’s exploration team has recognized that gold mineralization, in particular higher-grade material, is also controlled by steeply dipping structures and has adopted the practice of drilling inclined holes in order to better constrain gold distribution. The mine undertakes drilling on annual basis for Mineral Resource and Mineral Reserve definition, and also undertakes extensive drilling for grade control purposes. The blast hole database has all records dating from 1985 and includes 1,236,106 blast holes.

Annual Information Form - 25 - Sampling, Analysis and Data Verification Sample preparation protocols applied to the drill samples have produced sub-samples of good quality and appropriate for assay analysis. The assay process has been monitored by QA/QC programs during all drilling and sampling campaigns. The assay results produced have been shown to be of good quality and appropriate for use in resource estimation. Sample security protocols have been applied to all drilling and sampling by the various exploration and operating entities from the beginning of the operation. During that time, there have been no security breaches or security incidents. All samples have been securely handled, transported, and processed. Bechtel Corporation (1984) reported that Gold Fields Limited (Gold Fields) compared the results of RC and core drilling and concluded there was no bias in either type of drilling. During the initial reserve estimation, Gold Fields also made a comparison of block estimates based on drill holes with block estimates based on four or more bulk samples within each block. The mean grades of 50 blocks were within 2%. In addition, Gold Fields made a comparison of the grade estimates for 1,122 blocks based on 141 ft. spaced drilling with grade estimates of the same blocks based on drill spacing averaging less than 100 ft. The difference in the means of the block estimates was less than 1%, although individual blocks did not compare well. Independent Mining Consultants Inc. (IMC) in 2006 did a comparison of the drilling data with the blasthole data by pairing drill hole composites with the closest blasthole within 10 ft. The summary statistics compared well, indicating good agreement between these two key data sets. IMC (2006) believed the sampling database at Mesquite was adequate to develop the resource model, Mineral Resource estimate, and ultimately the Mineral Reserve estimate to the level of accuracy required for the feasibility study at that time. Mine Development Associates (MDA) completed an analysis that indicated the possibility that the RC data are slightly high biased compared to core. IMC proposed that, if this was true, it had been accounted for in the resource modelling, mostly due to, in the opinion of IMC, fairly aggressive grade capping. The comparison of blasthole data to RC data does not show this possible bias. Original assay results from the individual drill programs are located in the hard copy files containing drill hole logs and assay sheets. In 2014 Roscoe Postle Associates Inc. (RPA) compared the assays from the original assay certificates with the entries in two diamond drill logs and found no errors. The data are adequate to use as the basis for Mineral Resource estimation and Mineral Reserve definition. Mineral Processing and Metallurgical Testing Previous operators of Mesquite have completed several metallurgical test work programs focused on heap leaching. Programs have been completed on-site and also by industry recognized commercial laboratories. As part of the heap leach control, and operating philosophy at Mesquite, column tests are conducted on material corresponding to different production periods. Recently, these have been based on mined ore blocks. These column tests are conducted on composite samples of the heap leach feed and run on an as-received basis with no size reduction or additional lime added. These testing programs include at a minimum the following: Direct Head Analyses, including: Column Test Fire Assay Head Assays, Column Test Cyanide Soluble Head Assays, Column Test Feed Sieve Analysis with Assays; Column Test Analyses, including: Daily solution analyses (effluent volume pH, free cyanide, and gold), Column Test Fire Assay Tail Assays, Column Test Cyanide Soluble Tail Assays and Column Test Tailing Sieve Analysis with Assays.

Annual Information Form - 26 - At the completion of the column test leach cycle, the column charges are emptied, air dried and sampled for tail screen assays. The tail screen assay results are used to calculate the head grade which is the basis for the recovery calculation. Mean gold recoveries for the Heap Leach Feed column tests was 68.1% gold with a median gold recovery of 71.1%. The gold recovery ranged between 40.2% and 96.6%, with an upper quartile of 79.7%. It should be noted that poor metallurgical response observed in the low recovery column tests appear to be a function of short leach cycles, i.e. 40 to 50 days and/or issues with leach solution chemistry, primarily pH. The relevant production data to be considered is from the period between July 2007, when the mine reopened, and year-end 2019. During this period approximately 215 million tons of ore containing 2,595,300 oz of gold have been placed on the heap leach pads with an average grade of 0.0121 oz/t Au. By December 2019, a total of 1,626,600 oz of gold had been produced, having an overall cumulative recovery of 62.7% (without accounting for residual leaching of material stacked as of December 31, 2019). Annual apparent recoveries (annual ounces recovered / annual ounces stacked), for the period 2007 through 2019 indicate that the apparent recovery required roughly five years to reach steady state at c. 61% recovery. This is a function of the initial lag phase in leaching fresh ore in 2007 and 2008, as well as increases in tonnage and declining grades. Also, during 2016 there was an upset condition owing to issues with solution chemistry, namely pH and cyanide concentration, resulting in deferred production. This is seen in the increase in apparent recovery in 2017 as these conditions began to be rectified. An increased stacking rate in 2019 resulted in a drop of apparent recovery but is expected to recover during the 2020 and 2021 production years. The gold recovery curve peaked in 2011 at 67.4% and has declined to the 64% range since, owing to increased tonnage to the heap, lower head grades, and higher mass fraction of the non-ox material being placed on the heap. It is reasonable that the previously reported gold recovery projections of 75% for oxide and 35% for non-oxide, are correct. Residual leaching of leach pad material is anticipated to extend for two to three years after final ore is placed. Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimate Mineral Resources at Mesquite are comprised of in-situ resources (as in previous years) and the newly added waste dump resources. The Mesquite In-situ Mineral Resource estimate was prepared by Ali Shahkar, P.Eng. of LGGC. The Waste Dump Mineral Resource estimate was completed by Robert Sim, P.Geo. of SGI. Bruce Davis, FAusIMM, of BDRC assisted both Ali Shahkar and Robert Sim. The resource estimate presented in this report is based on a database provided by Equinox on January 13, 2020, which included the results of drilling campaigns and re-logging and geological interpretations carried out by Equinox in 2019. Mineral resources presented in this report are based on the resource- limiting pit, mining (or mined-out) surface and topographic surface as of December 31, 2019. The resource limiting ultimate pit shell is derived using an assumed gold price of $1,500 per ounce, 2020 budget operating costs and metallurgical recoveries of 75% for oxide (OXD) and oxide-transition (OXD-TR) and 35% for transition and non-oxide (NOX) and non-oxide-transition (NOX-TR) rocks. The mineral resources contained within the resource limiting ultimate pit shell exhibit reasonable prospects for eventual economic extraction as required under NI 43-101. The Mineral Resources at the Mesquite Mine deposit have been classified in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves (May 2014). The classification criteria are based on the distance-to-sample data and are based on the relative degree of confidence in the block grade estimate. These parameters are, in part, based on the prior production history and information at this operation.

Annual Information Form - 27 - The Mineral Resources, exclusive of Mineral Reserves, are listed in Table 1. Mineral Resources have been segregated based on oxide type. The base case cut-off grade for OXD/OXD-TR material is 0.0025 oz/t Au and 0.0053 oz/t Au for NOX/NOX-TR material. Waste dump resources are reported at a cut-off grade of 0.004 oz/t gold, which is used for mining of waste dump material. There are no known factors related to mining, metallurgical, infrastructure, environmental, permitting, legal, title, taxation, socio-economic, marketing, or political issues which could materially affect the mineral resource. The eastern extent of the mineral resource, referred to as the Rainbow area, encroaches on an existing public roadway and full extraction of the full resource in the area would require moving the existing road. There are no known reasons that full access to the resource in this area could not be achieved in the future.

There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves. Inferred Mineral Resources have a greater amount of uncertainty as to their existence and whether they can be mined legally or economically. It is reasonably expected that a majority of resources in the Inferred category could be upgraded to Indicated (or Measured) Mineral Resource with continued exploration. Mineral Reserve Estimate The Proven and Probable Mineral Reserves at Mesquite have been classified in accordance with the CIM Definition Standards (2014). Mineral Reserves are defined within a mine plan, with open pit phase designs guided by Lerchs- Grossmann optimized pit shells.

Annual Information Form - 28 - Notes: 1. This mineral reserve estimate is as of Dec 31, 2019 and is based on the mineral resource estimate dated Dec 31, 2019 for Mesquite Mine by LGGC. 2. The mineral reserve calculation was completed under the supervision of Gordon Zurowski, P.Eng. of AGP., who is a Qualified Person as defined under NI 43-101. 3. Mineral reserves are stated within the final design pit based on a $1,350/oz gold price. The cut-off grade varied by material type from 0.004 oz/t for oxide and oxide-transition and 0.009 oz/t for non-oxide transition and non-oxide materials. The mining cost averaged $1.45/t mined, processing costs are $2.05/t ore and G&A was $0.70/t ore placed. The ore recoveries were 75% for oxide and oxide-transition, and 35% for non-oxide transition and non-oxide material. Mining Operations Mesquite is an operating open pit mine with ore processed by heap leaching using a CIC circuit to recover gold. Total mine production is capped at 65 million tons per year based on a restriction of the air quality permit. Highwall slope angle criteria vary by area and pit. In general, the steepest walls are on the south side of the property and the shallowest in the northeast. In general, the inter-ramp angles vary from 29 to 42 degrees depending on pit area and wall orientation. The final pit designs are based on pit shells using the Lerch-Grossman algorithm in Mine Plan software. Pits were generated using a revenue factor of 1.0 or gold price of $1,350/oz. These pit shells were used as the basis for the final phase designs in each pit area. The pit optimization utilized metallurgical recoveries of 75% for oxide ores and 35% for non-oxide ores. The detailed pit phase designs at Mesquite are based on the pit optimization shells generated with the current resource model. Three pit areas are considered in the Mineral Reserves statement: Brownie (1-phase), Vista East (2-phases), Vista West (1-phase) plus two areas in the Big Chief waste dump. Each pit has been designed to accommodate mining by the existing mining fleet. Mining occurs on 30 ft. lifts with catch benches spaced every 60 ft. vertically. The haul roads are 100 ft. in width with a road grade of 10%. Mining cut-offs for the mine plan are 0.14 g/t for oxide and oxide-transition and 0.31 g/t for non-oxide transition and non-oxide material. The mine schedule delivers 28.2 million tons of Proven and Probable Mineral Reserve ore grading 0.62 g/t to the heap leach pad over a current design life of 2.5 years. The ore tonnage is made up of 0.23 million tons of Proven Mineral Reserves and 27.9 million tons of Probable Mineral Reserves. The waste tonnage totals 120.9 million tons to be placed in various waste rock facilities or backfill in the existing pit workings. The overall strip ratio is 3.89:1. The mine schedule utilizes the pit and phase designs to send a peak of 12.9 million tons of ore to the pad in 2020 and then lesser amounts in the following years. The mine equipment fleet is comprised of two Terex RH340 hydraulic shovels (44 yd3) which are the primary loading units. These are supported by two Cat 994H front end loaders (26 yd3) and a backup LeTourneau L1350 (28 yd3) front end loader. The haul truck fleet is comprised of sixteen Terex MT3700 (205 ton) and six Caterpillar 789D (200 ton) trucks. The mining fleet has additional support equipment in the form of track and rubber-tired dozers, and graders. The mine operates on a work schedule of two 12-hour shifts per day, seven days per week. Drilling is performed with a fleet of rotary down-the-hole hammer drills (8¾ inch diameter) on a nominal 26 x 26 ft. pattern or a 28 x 28 ft. pattern. Blasting is controlled to minimize back break. The overall powder factor is 0.26 to 0.32 lb/ton. Holes are drilled to a 30 ft. bench height with 3 ft. of sub-drilling for a total depth of 33 ft.

Annual Information Form - 29 - The MineSight generated pits showed the Rainbow pit area could potentially be included in the future once appropriate approvals are obtained to continue mining, and the highway is relocated. That material remains in the resource category and has not been considered for reserves. This represents a future opportunity. Processing and Recovery Options The Mesquite processing facilities were originally designed to process 8,800 gpm of pregnant gold solution producing up to 140,000 ounces of gold annually from a combination of 98 million tons of oxide ore grading 0.016 oz/t and 30 million tons of non-oxide ore. Owing to the decreasing head grades as the mine developed, ore stacking, and solution processing rates have increased to maintain the nominal 140,000 ounce per annum production rate. Nominal solution flows to and from the heap are approximately 13,400 gpm of barren solution to the heap and approximately 12,000 of pregnant solution to the ADR circuit. The difference between the two flows accounts for fresh ore wetting and evaporation. The processing facilities include the following operations: heap leaching; carbon adsorption using CIC processing; desorption and gold recovery; reagents and utilities; and water services. During early operations, the ore was crushed to a nominal 2-inch passing size. However, since the operation was re- started in 2007, only ROM ore has been stacked and leached. ROM ore, with lime added for pH control, is trucked to the heap leach pad. The ore is stacked to a height of 20 ft. The ultimate pad height has been increased from 200 to 300 ft. Mesquite became re-certified in accordance with the International Cyanide Management Code in May 2018. Infrastructure, Permitting and Compliance Activities The major assets and facilities of WMMI are an open-pit gold heap leach mining operation with a CIC processing circuit. A smelting furnace, assay and metallurgical laboratories, administration building, truck shop facility, and other required infrastructure are also located on the mine site. Electricity for the mine is provided through a 92-kV power line. Power is supplied to the site by Imperial Irrigation District Power Company. Power is stepped down from 92 kV to 13.2 kV on-site. All power distribution from this point onwards is distributed on equipment and infrastructure owned by WMMI. Water for the project is supplied from the existing Vista well field located approximately two miles south of California State Highway 78. The two current active wells are deemed capable of supplying the water requirements for both WMMI and the LACSD operations. A new 18-inch diameter line is in place; and the two existing pumping systems are capable of supplying approximately 2,000 gpm of fresh water to the operation. The mine will require about 1,000 gpm, and the landfill will require a maximum of 700 gpm when operating at full capacity. Leach pad capacity as of December 31, 2019 was 30.7 million tons. That will complete Leach Pad 7 (designed by Tetra Tech) and Leach Pad 6 to the full 300 ft. height. To place the reserve leach tonnage on the pad, an additional 2.4 million tons of capacity is required. Mesquite is engaged in the permitting process to expand leach pad capacity and does not feel this will be unduly withheld. Permitting and Compliance Activities Mesquite is a mature mine from an environmental, permitting and social perspective. Open pit mining and heap leach operations at the site date back to the 1980s. Throughout Mesquite’s ownership history (Gold Fields, Santa Fe Gold, Newmont, New Gold, and Equinox Gold) the mine has had a successful environmental track record and operating history. The environmental staff are “seasoned” and bring operating and compliance successes from previous operations and employment.

Annual Information Form - 30 - Equinox Gold has obtained permits and authorizations from federal, state, and local agencies to operate current facilities and activities. The closure and reclamation plan for Mesquite has been developed by WMMI with the assistance of independent consultants with the specific objective of leaving the land in a useful, safe, and stable post-mining configuration, capable of supporting native plant life, providing wildlife habitat, maintaining watershed functions, and supporting limited livestock grazing. Portions of the mine will be utilized by the Los Angeles County Sanitation District as a long- term landfill, and the mine’s planned development is integrated with this long-term use. Equinox Gold maintains several bonds to guarantee that proposed and approved reclamation activities will be fully funded and performed. Equinox Gold and its predecessors have developed plans and obtained federal, state, and local approvals for heap leach pads, waste disposal, site monitoring, and water management; both during operations and post mine closure. The mine operates under the “Consolidated Reclamation Plan (CRP)” which was approved in December 2016 and formally combined three separate Mine Identification Numbers under which the mine had previously operated. The CRP also included mining the Brownie Pit and updated a number of reclamation methods and requirements to modern standards of mine closure, reclamation, stabilization, and revegetation. The mine operates under its established permits and rights. Equinox Gold reports excellent working relationships with regulatory agencies and the public. No major violations with operating permits have occurred and relationships with nearby communities and agencies are amicable with no adversarial relationships or issues. Current Capital and Operating Costs The following information provides a summary of activities and expenditures completed in 2023 and the Company’s forecasts for 2024 for Mesquite.

Annual Information Form - 31 - Table 4: Operating Costs Description Units 2023 Costs ($) 2024 Budget ($) Mining open pit US$/t mined 1.66 1.92 Processing US$/t processed 3.01 17.73 Site General US$/t processed 0.96 7.17 Notes: 1. Totals may not add due to rounding. 2. Operating costs include all mining, processing and general and administration costs including waste stripping. 3. Costs are variable depending on whether ore mined and milled is classified as oxide, transitionary or fresh rock. Costs are based on whether the material being processed is stockpiled or in situ material. Cost estimates in the tables above are based on the Mesquite mine plan and Equinox Gold’s current estimates as of December 31, 2023. Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates and changes to current mining operations or the mine plan. The current mine plan is based on existing Mineral Reserves. Ongoing exploration and analyses at operating mines are conducted with a view to identifying new Mineral Resources and upgrading existing Mineral Resources to higher confidence levels and potentially into new Mineral Reserves. If new Mineral Reserves are successfully identified, it may alter the current mine plan and potentially extend the mine life. Recent Exploration, Development, and Production Exploration A total of 6,888 m of reverse circulation drilling was carried out in 2023 including 5,339 m at the Ginger deposit and 1,550 m at the Rainbow deposit. Both drill programs included infill and growth-focused step-out components. Other exploration activities include on-going geological mapping of the main open pits to further enhance the geological model. There is no exploration drilling planned at Mesquite for 2024. Development During 2023, the sustaining capital expenditures were $10.7 million, primarily related to capitalized stripping. Non- sustaining expenditures were $17.2 million, primarily related to lease payments for haul trucks, Ginger pit capital stripping that commenced, and exploration costs. Mesquite’s budgeted sustaining expenditures of $5 million for 2024, primarily relate to processing equipment. Budgeted non-sustaining expenditures of $82 million primarily relate to capitalized waste stripping of the Ginger pit. Production Mesquite produced a total of 87,753 ounces of gold during 2023 at cash costs of $1,105 per ounce and AISC of $1,251 per ounce. Mesquite production guidance for 2024 is 75,000 to 85,000 ounces of gold. Costs guidance for 2024 is cash costs of $1,345 to $1,445 per oz and AISC of $1,410 to $1,510 per oz.

Annual Information Form - 32 - Castle Mountain Mine Castle Mountain is a ROM heap leach gold mine located in California, USA, approximately 200 miles north of Equinox Gold’s Mesquite mine. Castle Mountain produced more than 1.2 million ounces of gold from 1992 to 2004, when production ceased due to low gold prices. The property was substantially reclaimed from 2004 to 2012, but operating permits remained in good standing. Castle Mountain is being developed by Equinox Gold in two stages. Phase 1 construction was completed in 2020 with commercial production achieved in November 2020. The Company completed a feasibility study for the Phase 2 expansion in March 2021, outlining plans to extend the mine life and expand production to more than 200,000 ounces of gold annually. In March 2022, the Company applied to amend existing permits to accommodate the Phase 2 expansion. Unless otherwise indicated, the information that follows relating to Castle Mountain is based on, derived substantially from, and in some instances is a direct extract from, the Castle Mountain Technical Report. Technical information disclosed since the effective date of the Castle Mountain Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151. The information below is based on assumptions, qualifications and procedures that are set out only in the Castle Mountain Technical Report and reference should be made to the full text of the Castle Mountain Technical Report which Equinox Gold has filed under its SEDAR+ profile at www.sedarplus.ca, its EDGAR profile at www.sec.gov/EDGAR and which is also available on Equinox Gold’s website at www.equinoxgold.com. Project Description, Location and Access Castle Mountain is located in the historic Hart Mining District, at the southern end of the Castle Mountains, San Bernardino County, California, 60 mile (100 km) south of Las Vegas, Nevada. The project is in the high desert area near the Mojave National Preserve and Castle Mountains National Monument. Year-round road access is available from the city of Las Vegas, Nevada approximately 70 mile (113 km) by road north of the project. The road access is paved highway from Las Vegas to Walking Box Ranch Road, and then by an 18 mile (29 km) unpaved two-lane road to the project area. This existing access road is well maintained and of good quality for necessary vehicular access as required for construction and operation of the project. Surface Rights The Castle Mountain property includes eight patented claims and 1,226 unpatented lode, placer and mill site claims. Equinox Gold has full legal access to the project with respect to surface and mineral rights. There are no known dates of expiration to mining claims pertinent to the Project. Royalties Castle Mountain is subject to several royalties which are payable to different parties. The Franco-Nevada royalty applies to all ounces from the project and the other royalties are area specific. Royalties payable include: • 2.65% Franco-Nevada royalty applied to all ounces • 5.00% Conservation royalty • 2.00% American Standard royalty • 5.00% Huntington Tile royalty

Annual Information Form - 33 - History The Hart Mining District covers the southern end of the Castle Mountains. Several hundred old prospects, pits trenches, waste rock dumps and underground workings extend over an approximate two square mile (5.2 km2) area overlapping the project area. In 1907, three underground gold mines were brought into production at Oro Belle, Big Chief and Jumbo and by 1911 the mined veins were exhausted. A resurgence in exploration activity commenced in 1968 until the early 2000’s with a variety of operators. Viceroy Gold Corporation (Viceroy) together with MK Gold Corporation completed a feasibility study and commenced gold production at Castle Mountain in 1991. By 1996, the Jumbo South and Leslie Ann (JSLA) deposits were considered exhausted. Mining from the Jumbo pit ceased in 2001 due to localized pit-wall stability issues resulting in the deepest bench mined approximately 200 ft (61 m) above the planned pit design. Mining from the Oro Belle and Hart Tunnel deposits ceased in 2001 due to low gold prices. Heap leaching continued until 2004, primarily in a rinsing operation to recover residual gold values and reduce cyanide levels in the heap. Reclamation began in 2001 and by 2012 all criteria for successful reclamation had been met. A total of 1.24 Moz was recovered from 36.2 Mton (32.8 Mt) processed at an average grade of 0.043 oz/ton (1.47 g/t) with a combined average recovery of 80% from milled and heap leached ore between 1991 and 2004. Minimal exploration activity occurred between 2005 and 2011. NewCastle Gold Ltd (NewCastle) acquired the Project in 2012. Equinox acquired NewCastle on December 22, 2017 and NewCastle became a wholly owned subsidiary of Equinox. The transaction was a three-way merger between Trek Mining Inc, NewCastle Gold, and Anfield Gold Corp., with the resulting company renamed to Equinox Gold Corp. NewCastle has 100% of the right, title and beneficial interest in and to Castle Mountain Venture GP (CMV) which owns Castle Mountain. Geological Setting, Mineralization and Deposit Types The project is in the eastern Mojave Desert which transitions to the Basin and Range region to the north and the Colorado Desert to the south. The Castle Mountains are a relatively small range extending north-northeast from the northern end of Lanfair Valley in California into Piute Valley in Nevada. The project is located near the southern end of the Castle Mountain range with elevations at the Project site ranging from about 4,100 ft to 5,100 ft (1,250 to 1,555 m). Proterozoic metamorphic and plutonic rocks form the basement of the Castle Mountains; these are overlain by pre- volcanic sediments, and Miocene sedimentary and volcanic rocks. The oldest known unit in the stratigraphic package is metamorphic Proterozoic basement rocks comprised of a massive sequence of biotite schist, biotite gneiss and meta-granite. Locally overlying the basement rocks is a Proterozoic sedimentary sequence of conglomerate with lesser sandstone. The regionally extensive Peach Springs Tuff unconformably overlies the Proterozoic units. The Miocene-age Castle Mountains Volcanic Sequence (CMVS) includes all volcanic units above the Peach Springs Tuff and below the Piute Range volcanic rocks. The CMVS was emplaced during three intrusive-extrusive episodes between around 18.8 and 13.5 million years ago. The CMVS is defined by the Jacks Well formation characterized by epiclastic and volcanic rocks with minor mudstone, the Linder Peak rhyolitic volcanic and volcaniclastic rocks and the Hart Peak rhyolite and late dacite dikes. Linder Peak is represented by a complex suite of volcanics and volcaniclastics including flow-domes, and clastic tuffs comprised of monolithic breccia, polylithic breccia, and ashfall tuffs. The Castle Mountain project is classified as a low-sulfidation epithermal gold deposit. CMVS rocks are the primary host of epithermal gold mineralization at the project. Structure and associated rock porosity-permeability characteristics are the first-order control on the distribution of gold. Silica alteration and iron oxide minerals generally occur with gold mineralization. Gold and electrum are the dominant gold-bearing minerals identified from gold deportment studies.

Annual Information Form - 34 - Exploration Exploration by NewCastle includes an airborne LiDAR survey, geophysical surveys including Transient Electromagnetic (TEM) and gravity, detailed mapping and surface grab and chip sampling. The deposit area exposures were mapped in detail and combined with a comprehensive geochemical and petrographic study of the rock types to evaluate the structural and stratigraphic setting. NewCastle exploration work was streamlined to create a framework for logging and relogging that was integrated into a refined geologic model including lithology, oxidation, structure, and alteration models for the Castle Mountain Technical Report. Grid-controlled rock sampling was conducted over seven prospective areas to expand on the rock and soil sampling completed by Viceroy. Drilling Drilling on the project is summarized by the material type intersected, the in-situ hard rock or the backfill and waste dump materials, respectively. Purpose designed drill holes have been completed to support the Castle Mountain Technical Report, including drilling samples for metallurgical testing, infrastructure condemnation, geotechnical study, and potential water sources. Diamond, RC, and conventional rotary (rotary), drilling methods have been used within the hard rock with a total of 1,557,140 ft (474,597 m) within 2,111 holes. The legacy drilling completed by Viceroy was completed entirely within hard rock material using rotary, RC and diamond drilling methods for a total of 1,184,180 ft (360,920 m) within 1,772 drill holes. NewCastle completed an additional 372,960 ft (113,677 m) of hard rock drilling in 339 drill holes at the project, primarily using angled RC and diamond core drilling to improve the geological understanding of the deposits. The JSLA backfill and waste dumps have been drilled exclusively by NewCastle in 1,685 reverse air blast (RAB) and RC holes with a total footage of 370,212 (112,835 m). Blastholes were used to monitor production during historical Viceroy operations. The samples cover the benches in the Jumbo and Oro Belle pits and a small portion of the benches in JSLA. Sampling, Analysis and Data Verification Samples from the Viceroy and NewCastle exploration drilling have been utilized in preparing the Mineral Resource Estimate. Core and RC sample intervals are a nominal 5 ft (1.5 m) length but range from 2 ft to 7 ft (0.6 - 2.1 m) in length. Viceroy drill hole samples were collected at 5 ft (1.5 m) intervals over the entire length of each drill hole. Routine pulp duplicate analyses were performed at the primary lab. The QA/QC practices implemented by Viceroy do not have current records; however, check assay samples submitted to umpire commercial labs and the Castle Mountain mine lab (that was in operation at the time Viceroy operated the mine) did not indicate systematic bias or accuracy issues with the original assays from the primary labs (Temkin, 2012). Legend and Rocky Mountain Geochemical (RMG) in Reno, Nevada were the primary laboratories. Both laboratories were independent of Viceroy; however, neither was accredited. Viceroy drill hole samples were analyzed for gold and silver by fire assay on a one-assay ton (29.166 g) subsample followed by AAS finish, with samples returning gold values greater than 0.100 oz/ton (3.43 g/t) being re-assayed by fire assay on a one-assay ton subsample with a gravimetric finish. NewCastle drill hole samples were prepared and assayed by ALS Global (ALS) or Bureau Veritas (BV), formerly Inspectorate, at their facilities in Reno or Elko, Nevada. Check assays were completed at American Assay Laboratories in Sparks, Nevada. All the laboratories are International Standards Organization (ISO) accredited operations which are independent of Equinox Gold. Gold was assayed by 1.06 oz (30 g) fire assay with AAS finish. Gold assays returning greater than 0.2917 opt (10.00 g/t) gold were re-assayed by fire assay with a gravimetric finish and gold assays returning greater than 0.006 opt (0.2 g/t) gold were analyzed for gold cyanide solubility.

Annual Information Form - 35 - Core and chip samples from diamond, RC, and RAB holes were transported to the secure on-site logging facility where they were processed and prepared for shipment by NewCastle. NewCastle maintained a QA/QC sampling program, including insertion and review of coarse blanks, certified reference materials (CRM), and duplicates. Sample shipments are shipped directly to the independent laboratory for preparation and analyses. NewCastle operations follow a standard operating procedure for processing, data collection, and sampling of the drill holes. All samples have adequate security and tracking measures employed during preparation and transport. Records of the drilling and samples are retained at the project site and at the Vancouver office. Mineral Processing and Metallurgical Testing Significant metallurgical testwork has been performed on Castle Mountain samples from 2015 to 2020. Given the intention to process lower grade ore on a leach pad and higher grade ore using conventional milling with Carbon-in- Leach (CIL), extensive testing was conducted for each process route and on a wide variety of samples. Data from this work along with historical production data has formed the basis for the project process design criteria. Testwork performed in 2020 has supplemented extensive test programs previously conducted in 2015 and 2018. Drill core samples were used, and the focus was on expanding the metallurgical understanding of the material to be processed through increased spatial and lithological representation within the mineral resource. The key testwork carried out included: • Column leach tests on heap leach grade ore using the same parameters as in prior testing to verify and supplement the results. • Column load permeability tests. • Gravity concentration followed by leaching of the gravity tails and whole ore leaching of higher-grade mill feed samples. Additional test programs conducted in 2020 to support the Castle Mountain Technical Report include: • Mineralogical analysis and gold deportment study. • Materials handling and comminution tests. • Carbon loading and oxygen uptake tests. • Cyanide detoxification tests. • Thickening, tailings filtration and slurry rheology tests. • Filtered tailings geotechnical stability analysis. • Testwork to determine the potential amenability to ore sorting. Castle Mountain ore can be generally characterized as friable but moderate to relatively hard based on the testwork considered. Based on the testwork, bond ball work indices ranged from 12.3 to 18.0 kWh/ton (13.6 to 19.8 kWh/t). A weighted average of 15.2 kWh/ton (16.7 kWh/t) based on lithology was selected for the design of the grinding circuit. The Axb results from seven SMC tests ranged from 38.1 to 56.1 while the 80th percentile was 43.0. The arithmetic average gold recovery from all column leach tests was 80%, while the weighted gold recovery based on ounces per lithology type was 82%. The historical production data from 1992 to 2004 was over 76% recovery specifically for the heap leach ore. Considering lab and historical operating data combined with the plan to leach ROM size ore, the permeability, and effective leaching of the side slopes, the expected LOM heap leach gold recovery is expected to be 67% during the LOM operation and 74% after final rinsing. For mill grade ores processed through the mill with gravity concentration and a leach/CIL circuit with 30 hours of retention time, an overall gold recovery of 94% is expected.

Annual Information Form - 36 - Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimate The Mineral Resources presented below conform with the CIM Definition Standards (2014), have been prepared according to CIM Best Practice Guidelines (2019), and are reported in accordance with NI 43-101. Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the mineral resources will be converted into mineral reserves. Inferred resources have a greater amount of uncertainty as to their existence and whether they can be mined legally or economically. It is reasonably expected that the majority of Inferred resources could be upgraded to Indicated (or Measured) with continued exploration. In order to sufficiently test the reasonable prospects for eventual economic extraction by an open pit, pit shells were generated using the variable slope Lerchs Grossmann algorithm in Hexagon’s MinePlan® software. The results of the pit optimization partially form the basis of the Mineral Resource Statement and are used to constrain the Mineral Resource with respect to the CIM Definition Standards. Pit optimization does not constitute an attempt to estimate reserves. A summary of the Measured, Indicated and Inferred Resources exclusive of Reserves are summarized in the following table. Areas of uncertainty that may materially impact the Mineral Resource estimate include commodity price assumptions, metal recovery assumptions, mining and process cost assumptions, pit slope angles and applied top cut values. In the opinion of the QP there are no known environmental, permitting, legal, title, taxation, socio- economic, marketing, political, or other relevant factors which would materially affect the Mineral Resource estimate.

Mineral resources from Castle Mountain Project presented herein have an effective date of June 30, 2020. Mineral Reserve Estimate The Proven and Probable Mineral Reserves at Castle Mountain have been classified in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves. The project Mineral Reserves are based on the conversion of the Measured and Indicated Resources within the Castle Mountain Technical Report mine plan, with open pit phase designs guided by Lerchs-Grossmann optimized pit shells. The Mineral Reserve estimate for Castle Mountain, effective June 30, 2020 is summarized in the following table. The Mineral Reserves have been reported using a cut-off grade of 0.005 opt (0.17 g/t) gold.

G&A was $0.79/t ore processed. 6. The average process recovery was 73.9% for ROM and 94.5% for milling. 7. Mineral Resource is exclusive of Mineral Reserves. Mining Operations Mining is an open pit operation using conventional diesel-powered truck and shovel mining equipment. The current Phase 1 operation consists of a 14,000 ton/d (12,700 tpd) ROM operation with a focus on mining backfilled material that was placed in the JSLA pit from the previous mining operation 20 years ago. Crushing and agglomeration was introduced in 2022 to improve leach time and recoveries. The Phase 2 expansion will increase production to 53,500 ton/d and extract hard rock material from open pits which will be drilled, blasted, and loaded to mine trucks using hydraulic shovels and wheel loaders. Phase 2 mine production is split with 50,000 ton/d (45,400 tpd) to the heap leach and 3,500 ton/d (3,200 tpd) to the mill. The Phase 2 mine plan includes 14 years of operation expanding the overall life of mine (LOM) to 19 years, with an additional estimated three years of heap rinsing, and delivering 266.6 Mton (241.9 t) of ROM heap leach ore with an average diluted grade of 0.012 opt (0.40 g/t) gold to the leaching operation. The mill will commence operation one year later and will process 17.7 Mton (16.1 t) of ore with an average diluted grade of 0.068 opt (2.28 g/t) gold. In some years a small portion of ROM ore will be crushed and re-directed to the mill. Five pit areas are considered in the reserves statement with pits at JSLA (3 phases), Jumbo, Oro Belle, East Ridge (2 phases) and South Domes (2 phases). There is a total of nine phases of open pit mining starting with JSLA backfill and moving north, and then to South Domes to complete the operation. The mining sequence of the phases allows for backfilling of waste as the pit reaches final limits. The mine plan incorporates the following elements: • Staggered mining equipment deliveries in Year 4 and Year 5; • Ramp up overall mining rate to 60 Mton/y (54 Mt/y) through to Year 8 then expand gradually to 80 Mton/y (73 Mt/y) through to Year 16 when production begins to drop through Year 19; • Overall sequence of development in the JSLA, Jumbo, Oro Belle and East Ridge area is clockwise development to final to pit limits in each area to allow for an orderly sequence of backfilling waste as pits are completed; • Sequence at South Domes is an initial southwest pit with an expansion to the northeast; and • The resource block model was developed on 20 ft (6.1 m) benches. The mine design was developed using the 20 ft bench height with triple benching to 60 ft between design catch benches or berms. Operations are planned for a 30 ft (9.1 m) bench height. Sinking rates in the schedule were limited to 300 ft/y (91 m/y) or the equivalent of 10 benches/year. Drills, loading units and support equipment appropriate for mining a 30 ft bench height have been selected for the mine plan and associated cost estimates.

Annual Information Form - 38 - Phase 1 mining is to be completed by contract mining services. Mine supervision and technical management will be handled by the CMV mining team while all other mining functions will be the contractor’s responsibility. A transition to operator owned mining services or fleet will start prior to Year 5 in parallel with Phase 2 mining. Full Phase 2 mining production coincides with the start of the fully expanded processing facilities, estimated to be in Year 6. The total in-pit waste is 701.9 Mton (636.8 Mt) which is to be placed in the various waste rock management facilities and within open pits once final pit limits are reached. The waste includes 15.0 Mton (13.6 Mt) of Inferred Mineral Resources within the ultimate reserve pit limits which presents an opportunity for future resource classification conversion. The overall strip ratio is 2.47:1. Final waste dump slopes are 2H:1V or 26.5°. There is a northwest waste dump and southeast waste dump designed within the mine property boundary. The mining equipment will operate on 30 ft (9.1 m) high benches with double benching in waste, up to 60 ft (18.2 m) high. Berms will be left on alternate benches in hard rock. Wall slope design recommendations have been implemented for inter-ramp slopes with variable berm widths and bench face angles. Inter-ramp slope angles are determined by geological domains which vary from 48 to 52°, with modified slope angles within structural domains of 40 to 46°. Bench face angles vary from 60 to 79° depending on the domain and host lithology. Equipment sizing for ramps and working benches is based on the use of 250-ton rigid frame trucks. Haulage and in- pit access roads will be double lane access and have 100 ft (30m) width, which is three times the equipment width plus berm and ditch. The maximum ramp gradients are 10% in-pit but can be constructed to 8% to maximize productivity. Working benches were designed for 35 m to 40 m minimum on pushbacks, although some push-backs do work in a retreat manner to facilitate access. Alluvium, backfill, and waste dump material will be free-digging. Hard rock will require drilling and blasting. Ore grade control will utilize rotary blast holes drilled across a full bench height of 30 ft (9.1m). Blastholes will be grid drilled to facilitate breakage and will be loading with ammonium nitrate and emulsion explosives. The blastholes will be sampled to provide analytical results for planning. Drilling will be in advance of the mined benches to allow proper short-term planning. Heap leach ROM ore will initially be hauled to the existing Phase 1 leach pad. In Phase 2 of the LOM plan, ROM will be hauled to a new, adjacent Phase 2 leach pad that will be developed progressing from South to North, then towards the West. Mill feed will be placed in a stockpile adjacent to the primary crusher and re-handled by wheel loaders to feed the crusher. Processing and Recovery Operations The current operation consists of a 14,000 ton/d (12,700 tpd) ROM heap leach operation with gold recovery in carbon columns. Crushing and agglomeration was introduced in 2022 to improve leach time and recoveries. The planned expansion for Phase 2 will include a 50,000 ton/d (45,350 tpd) ROM heap leach and a new 3,500 ton/d (3,175 tpd) crushing, milling and leach/CIL plant for recovering gold and silver from mill grade ore. For Phase 2, the heap leach pad will be designed to process 18.2 Mton (16.5 Mt) annually at an average life of mine (LOM) grade of 0.012 opt (0.54 g/t), while the mill will be designed to process approximately 1.3 Mton (1.2 Mt) annually at an average LOM grade of 0.068 opt (2.28 g/t). The Phase 2 expansion will extend operations to approximately 19 years with an additional estimated three years of heap rinsing as part of reclamation where gold will continue to leach and be processed. ROM heap leach ore will be loaded into haul trucks and stacked in 25-foot (8 m) lifts on the heap leach pad to be leached with a dilute cyanide solution using a drip irrigation system for 80 days. After percolating through the ore, the pregnant gold and silver bearing solution will flow by gravity to a pregnant solution tank where it is pumped to a 12,000 gpm (750 L/s) carbon-in-column (CIC) circuit to recover the precious metal from solution. The carbon adsorption circuit will consist of two trains of five cascading carbon columns.

Annual Information Form - 39 - ROM mill ore will be loaded into haul trucks and dumped on the ROM storage pad for recovery by a front-end loader and feed to a two-stage crushing plant intended to reduce ore to 80% passing ½ inch prior to feeding a single ball mill. The ball mill will be a 16.5 ft x 21 ft (5 m x 6.4 m) long equipped with a single 3,300 hp (2,460 kW) wound rotor induction motor with a variable frequency drive and process a nominal throughput of 162 ton/h (fresh feed), producing a final product P80 of 150 μm. A batch gravity concentrator will treat a portion of the grinding circuit circulating load to recover any gravity recoverable gold with the concentrate being processed in a batch intensive leach reactor (ILR). Cyclone overflow will flow by gravity to a 68 ft (21 m) diameter high-rate pre-leach thickener which will thicken the slurry to 45-50% solids. Thickened slurry will be pumped to a hybrid Leach/CIL circuit using a series of seven agitated tanks (30 hours retention time) using cyanide solution in the presence of activated carbon to extract the gold. The thickener overflow will flow by gravity to the non-cyanide solution tank to be used as makeup water in the grinding circuit. The carbon handling circuit is designed to handle carbon from both the heap leach CIC circuit and the mill-CIL circuit in separate batch processes. Loaded carbon at an average of approximately 15 tons/day (13.6 tpd) will be washed with hydrochloric acid and stripped under pressure. An indirect propane fired rotary kiln will treat up to 18 tons (16 t) of carbon per day, equivalent to 100% regeneration of stripped carbon. The resulting pregnant solution from the carbon handling and ILR circuits will undergo electrowinning in four EW cells operating in parallel and the recovered precious metal sludge will be dried in a retort furnace to recover mercury. The dried sludge will be refined in an induction furnace to produce gold and silver doré. Doré bars will be the final product and will be stored in a vault within a secure area prior to shipment. Leached slurry from the Leach/CIL circuit will report to a cyanide recovery thickener to recycle as much water and cyanide as possible back to the process. Flocculant will be added to the to aid in settling to produce a thickened product at approximately 60% solids, which will be treated in an SO2/oxygen cyanide destruction process. The final tailings will be pressure filtered in two of three tailing filters (1 standby). The filter cake at approximately 18% moisture will discharge to a stockpile to be reclaimed by front end loader and loaded into articulated trucks for haulage to the filtered tailings facility. Process water needs for the recovery plant will fluctuate seasonally. Make-up water for the heap leach will change with the amount of evaporation and precipitation each month. Net evaporative losses will range from 150 gpm to 700 gpm (10 L/s to 45 L/s), averaging approximately 400 gpm (25 L/s) annually, while ROM ore on the leach pad will need to be saturated with moisture at an average of 10% and this results in an average consumption of approximately 670 gpm (42 L/s). Additional water is required for the mill process and will be largely made up with recycled water. The project will mitigate the impact of water use by use of low evaporation buried drip emitters, limiting water in ponds with larger evaporative losses, use of binders and dust collectors that limit water needs for dust suppression and using extensive water recycling in the process. The Phase 2 expanded project is anticipated to account for 3,203,000 oz gold over the course of the mine life and rinsing of the heap leach pad. Infrastructure, Permitting and Compliance Activities Infrastructure The Phase 2 expansion will continue to utilize historic facilities and the recently built Phase 1 facilities to the greatest extent possible. Phase 2 infrastructure will increase in size to meet the expanded project parameters and include new site improvements to support the operation of the required new process and mining facilities. The project supporting infrastructure will include:

Annual Information Form - 40 - • Site access, on site and service road access (most currently in operation) • Mining haul roads (currently in operation and expanded) • Truck service shop, fueling station, tire change pad and wash facility • ROM ore stockpile area • Water supply and distribution systems • Surface water management • Lined filtered tailings facility • Topsoil reserve areas • Process maintenance building • Reagents storage and warehousing building • Security gatehouse including medical triage area and evacuation helipad • Communications system and plantwide process control Electrical power requirements for Phase 2 are approximately 10 MW and this is to be provided by a connection to grid power which will be routed to site via a new transmission line from an existing Nevada Energy (NVE) sub-station near Searchlight, NV, similar to that previously used at the site and along the same right of way. Additional options including solar power have been investigated and could be developed as part of the project construction. Filtered tailings from the mill will be produced at a moisture content of 19% to 22% by dry weight basis (16-18% wet basis) and will be delivered using 40-ton articulated dump trucks to a lined facility. Stacking of filtered tailings is considered best available technology for handling and placing this type of material. The tailings will be spread by dozer atop the reclaimed former Viceroy heap leach pad. Development of the filtered tailings facility will occur in four stages to allow for both the placement of appropriate volumes of material to match production and the rinsing of heap leach side slopes which will be directly abutted to the final filtered tailings facility footprint. The heap leach and filtered tailings will form a co-deposited and integrated facility. Rinsing is required to allow for recovery of residual gold ounces within the heap as well as to reduce cyanide levels to compliant levels within the placed heap leach material prior to final reclamation. By placing filtered tailings abutted to the new heap leach facility and on top of the historic leach pad, the area of disturbance on the site will be minimized. This will increase the long-term stability on the western edge of the facility and allow integrated management of solution between the tailings and heap leach facility, allowing for further recycle of cyanide. The Castle Mountain mine will be a net zero discharge facility with regards to water with the main water loss occurring via evaporation from the surface of the heap leach pad and filtered tailings facility. Water is also used in saturating the heap leach pad and dust control mitigation for roads and site development, as necessary. The Project site-wide water balance indicates an expected make-up water demand to range from approximately 1,150 gpm to 1,900 gpm (72 L/s to 120 L/s) depending on the season. In addition to the water use mitigation measures mentioned above, further water demand reduction will be attained through greater use of onsite dust suppressants, strategic seasonal construction planning during wetter months, and optimizing the heap leach make-up water requirements through efficiency improvements. Water supply at site includes three historical wells providing approximately 150 gpm (10 L/s) total and connected via existing underground pipelines to an existing 300,000 gal (1.1 ML) water tank, as well as two production wells, W-01 and W-02, with pumps installed in 2019 at the start of Phase 1 project. These production wells are located at the edge of the JSLA pit (W-01) and in the area of what will become the South Domes pit (W-02). These are bedrock wells which can produce approximately 400 gpm (25 L/s) total and are connected to a recently constructed 300,000 gal (1.1 ML) raw water tank. Additional water for the Phase 2 expansion is expected to be extracted from new wells. Recent water exploration has shown very good potential for both water near site and in a neighboring water basin. It is anticipated that once developed, wells in both areas will be able to produce between 500 and 1,000 gpm (32

Annual Information Form - 41 - and 64 lpm) of water each. The project expansion development includes the addition of new wells, and well pumps in both locations as well as an overland pipeline and booster pumps to meet the make-up water demands. Permitting and Compliance The mine operations encompass both public and private land. Accordingly, the County of San Bernardino (County) at the state level, and the United States Bureau of Land Management (BLM) at the federal level, have served as co- leading agencies for implementing environmental review. The current operation was issued a revised Mining Conditional Use Permit (CUP) by the County in August 2019 while the BLM issued a Decision Record and Finding of No Significant Impact (FONSI) in February 2020 approving the revised Mine and Reclamation Plan. These key permits along with others cumulatively provided authorization for current mine operations. The Phase 2 mine expansion is expected to require a new or updated environmental review (likely in the format of an EIS/EIR) as well as several new state and federal permits and amendments. The federal lead agency, the BLM, and the California state lead agency, the County, will cooperate to prepare a single environmental review document. Federal, state, county, and local agency officials will review and comment on the analysis provided through the environmental review process. The application for the Phase 2 permit amendment was submitted in March 2022. Economic Analysis The economic analysis was completed primarily utilizing a discounted cash flow model. Currency is provided in US dollars, unless otherwise noted. The following table summarizes the resulting project economics at a gold price of $1,500/oz. The Project after-tax NPV at a discount rate of 5% is estimated to be $639 million. The after-tax cash flow results in a 5.3-year payback period after start-up of commercial operation with an after-tax IRR of 17.5%. With leasing the mining fleet, the after-tax NPV remains at $639 million while the after-tax IRR improves to 18.3%, and the payback period is 5.4 years.

Totals may not add due to rounding. 2. Operating costs include all mining, processing and general and administration costs including waste stripping. 3. Costs are variable depending on whether ore mined and milled is classified as oxide, transitionary or fresh rock. Costs are based on whether the material being processed is stockpiled or in situ material.

Annual Information Form - 43 - Cost estimates in the tables above are based on the Castle Mountain mine plan and Equinox Gold’s current estimates as of December 31, 2023. Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates and changes to current mining operations or the mine plan. The current mine plan is based on existing Mineral Reserves. Ongoing exploration and analyses at operating mines are conducted with a view to identifying new Mineral Resources and upgrading existing Mineral Resources to higher confidence levels and potentially into new Mineral Reserves. If new Mineral Reserves are successfully identified, it may alter the current mine plan and potentially extend the mine life. Recent Exploration, Development and Production Exploration Exploration drilling at Castle Mountain in 2023 totalled 19,374 metres of RC drilling and included an infill drill program primarily designed to increase drilling density within the South Overburden and JSLA dumps to better support mining of mineralized material. There is no exploration drilling planned at Castle Mountain for 2024. Development During 2023 sustaining capital expenditures were $3.2 million and non-sustaining expenditures $8.8 million, primarily related to Phase 2 permitting and optimization. Costs at Castle Mountain are expected to remain elevated as a result of modifications to the crushing and agglomerating circuit to improve ore permeability and gold production. Budgeted sustaining expenditures at Castle Mountain in 2024 include $3 million of sustaining capital for a variety of equipment upgrades. For 2024 budgeted non-sustaining expenditures of $4 million include engineering and permitting work. Production Castle Mountain produced a total of 20,837 ounces of gold during 2023 at cash costs of $1,531 per ounce and AISC of $1,899 per ounce. Castle Mountain production guidance for 2024 is 30,000 to 35,000 ounces of gold, with cash costs of $2,045 to $2,145 per ounce and of AISC estimated at $2,125 to $2,200 per ounce. Production and cost guidance for the Castle Mountain Mine is subject to change pending completion of an internal evaluation of the Phase 1 operation. The mine is currently operating as a small ‘phase 1’ project designed to process mineralized material deposited in the open pits during prior mining operations while permitting and engineering for the Phase 2 expansion to more than 200,000 ounces of gold production per year is being advanced. As this permitting process is expected to continue into fiscal 2026, the Company is evaluating the Phase 1 operation to ensure appropriate allocation and preservation of capital, which could result in reduced operations-related activities and gold production from Castle Mountain Phase 1 through the permitting period.

Annual Information Form - 44 - Los Filos Mine Complex The Los Filos Mine Complex in Guerrero State, Mexico currently comprises three open pits, Los Filos, Guadalupe and Bermejal, and two underground mines, Los Filos and Bermejal. Ore from all deposits is processed using heap leach recovery. Los Filos began commercial production in 2008, was acquired by Leagold in 2017 and was subsequently acquired by Equinox Gold in March 2020 through the Leagold Transaction. On October 19, 2022, Equinox Gold published the results of an updated feasibility for a potential Los Filos expansion. Construction and operating a CIL plant concurrently with existing heap leach facilities would extend the Los Filos mine life and increase annual production to on average 280,000 ounces per year. Unless otherwise indicated, the information that follows relating to Los Filos is based on, derived substantially from, and in some instances is a direct extract from, the Los Filos Technical Report. Technical information disclosed since the effective date of the Los Filos Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151151. The information below is based on assumptions, qualifications and procedures that are set out only in the Los Filos Technical Report and reference should be made to the full text of the Los Filos Technical Report which Equinox Gold has filed under its SEDAR+ profile at www.sedarplus.ca, its EDGAR profile at www.sec.gov/EDGAR and which is also available on Equinox Gold’s website at www.equinoxgold.com. Project Description, Location and Access The Los Filos Mine Complex encompasses the three main open pit mining areas of Bermejal, Guadalupe, and Los Filos, as well as three underground mines of Los Filos South, Los Filos North (together with Los Filos South, called Los Filos Underground) and Bermejal Underground. The Los Filos Mine Complex consists of 30 exploitation and exploration concessions in active mining areas totalling 10,433 ha in the Eduardo Neri District, Guerrero State, Mexico approximately 180 km southwest of Mexico City. The property is centred on latitude 17°52’13” north and longitude 99°40’55” west (UTM Zone 14Q 1,976,300N 427,400E). Los Filos can be accessed by road or by helicopter or fixed-wing charter flight. The four-hour (240 km) drive from Mexico City follows National Highway 95/95D south to the town of Mezcala, then 18 km on a paved road to the mine site. In addition to the 30 mining concessions that cover the entire active mining areas, Equinox Gold holds 12 exploration concessions, including two concessions that have applications in progress, in Guerrero State, Mexico. The 42 concessions, which are 100% held by Equinox Gold through its indirect, wholly-owned Mexican subsidiary, Desarrollos Mineros San Luis, S.A. de C.V. (DMSL), are granted for 50-year durations; the expiration dates vary depending on the date of grant of the concession. Renewal dates range from 2032 to 2067. Details regarding such concessions, including applicable expiry dates, are listed in the Los Filos Technical Report. The surface rights held by the mine cover the area needed to support all infrastructure required for the mining operations and proposed future CIL plant, including access and power-line easements. The main obligations that arise from a mining concession, and which must be kept current to avoid its cancellation, are performing assessment work, paying mining taxes (duties), and complying with environmental laws.

Annual Information Form - 45 - Mining regulations establish minimum amounts that must be spent. Sales of minerals from the mine for an equivalent amount may substitute for minimum expenditures. A report must be filed in May of each year that details the work undertaken during the previous calendar year. Mining duties must be paid in advance in January and July of each year and are determined on an annual basis under the Mexican Federal Rights Law (Ley Federal de Derechos, DOF 09-04-2012). Duties are based on the surface area of the concession and the number of years that have elapsed since the mining concession was issued. Concessions are maintained on an annual basis by payment of appropriate fees, as determined by the Office of Economic Affairs (Secretaría de Economía) each year. Holders must also supply the Office of Economic Affairs with all activity, contracts, and agreements that affect the concession title to keep and maintain the Public Mining Registry current. The relevant Mexican federal and state authorities have granted appropriate environmental permits for Los Filos, including the area of the open pits. Los Filos secured 4,102 ha to cover surface rights required for the Los Filos mining operations, including the area of the three open pits, underground mine portals, process and ancillary facilities, roads, services, and a buffer area to allow for any future growth and potential exploration targets. Los Filos is subject to a 30% federal corporate income tax rate. Two mining royalty taxes are also payable to the government of Mexico: a 7.5% mining tax on earnings before interest, taxes, depreciation, and amortization; and a 0.5% gross revenue royalty tax levied on revenue from gold and silver sales. Net smelter return royalties to Servicio Geológico Mexicano, a department of the Mexican government, ranging from 2.5% to 3% are applicable to mining from five concessions of the Los Filos property. Two of those concessions are also subject to net smelter return royalties of 0.75% to 1.75% payable to LC Mines S.A. de C.V., a subsidiary of Agnico-Eagle Mines Limited. The existing Closure and Reclamation Plan is conceptual and addresses all existing facilities. The estimated closure liability in the Los Filos Technical Report of $50.9 million is based on the existing facilities at the end of 2021, and as such is exclusive of the majority of the future Bermejal Underground development, the proposed CIL plant, dry stack tailings facility and new electrical substation, and the future heap leach pad expansion. Bonding requirements under Mexican regulatory requirements, pertaining to the current operation, have been met. Current environmental liabilities are typical of those normally associated with active underground and open pit mining operations feeding a heap leach facility. To the responsible Qualified Person’s knowledge, other than as set out in this summary, there are no other significant factors or risks that may affect access, title, or the right or ability to perform work on Los Filos. History The following summarizes the Los Filos Mine Complex’s ownership, exploration and production history post-2003. In November 2003, Wheaton River Minerals Ltd. (WRM) gained 100% ownership of Los Filos through the purchase of Miranda Mining Development Corporation and associated agreements with Teck Corporation. In March 2005, Goldcorp Inc. (Goldcorp) acquired WRM, and therefore DMSL, the operator of Los Filos. Goldcorp also acquired the Nukay mine in 2008, which was subsequently integrated with the Los Filos operations as the Los Filos Underground mine. On March 22, 2005, Goldcorp’s wholly owned operating Mexican company Luismin acquired the Bermejal gold deposit from Minera El Bermejal, S. de R.L. de C.V., a joint venture between Industrias Peñoles S.A. de C.V. and Newmont Mining Corporation. On April 7, 2017, Leagold Mining Corp. (Leagold) acquired 100% ownership of Los Filos through the purchase of DMSL from Goldcorp and on March 10, 2020, Equinox Gold merged with Leagold. Goldcorp completed feasibility-level studies for Los Filos Open Pit, Bermejal Open Pit, and Los Filos Underground between 2005 and 2007. Open pit mining commenced at Los Filos in 2005. Underground production at Los Filos commenced in 2007, and the first gold pour occurred that year. In 2013, exploration drilling below Bermejal Open Pit encountered high-grade oxide mineralization that is now referred to as the Bermejal Underground deposit. A total of 259 Mt of ore at 0.74 g/t Au, containing 6.1 Moz Au, was mined by Los Filos from 2005 to June 30, 2022.

Annual Information Form - 46 - Reference should be made to the Los Filos Technical Report for further details on past exploration and production activities at Los Filos. SRK completed a Mineral Resource estimate reported for the Los Filos mine in 2019. Geological Setting, Mineralization and Deposit Types Los Filos is in the Guerrero Gold Belt near the centre of a large, approximately 200 km-diameter, circular feature known as the Morelos–Guerrero sedimentary basin. The basin consists of a thick sequence of Mesozoic platform carbonate and argillaceous rocks including the succession of the Morelos, Cuautla, and Mezcala Formations. The Cretaceous carbonate rocks were intruded by numerous early Tertiary-age granitoid bodies. The distribution of intrusions along northwest-trending belts is interpreted to reflect the control on their emplacement by pre-existing northwest-trending faults. Tertiary granodiorites that intrude the carbonate sedimentary units on the mine property include: the eastern and western Los Filos stocks, the Bermejal–Guadalupe stock, the Xochipala intrusion, and an unnamed granodiorite intrusion in the northeast portion of the property. Mineralization identified within the Los Filos property is typical of intrusion-related gold–silver skarn deposits. Gold skarns typically form in orogenic belts at convergent plate margins and are related to plutonism associated with the development of oceanic island arcs or back arcs. Mineralization is geologically controlled either by being hosted by, or spatially associated with, skarn development during contact metamorphism of the carbonates by the intruding granitoid rocks. The Los Filos stocks form two circular deposits, each approximately 1.5 km in diameter, with mineralization focused along the contacts with the host rocks. The Bermejal–Guadalupe stock forms on oblong shape over 5 km long, with the Bermejal deposit on the northern end, and the Guadalupe deposit approximately 2 km southeast of Bermejal; the stock continues further southeast to the San Pablo deposit. Massive magnetite, hematite, goethite, and jasperoidal silica, with minor associated pyrite, pyrrhotite, chalcopyrite, and native gold typically occur in the veins and metasomatic replacement bodies that develop at the contacts between the carbonate and intrusive rocks. Extensive, deep oxidation of the deposits (that occurred at the time of mineralization) has altered the mineralization into material that is amenable to cyanidation recovery techniques without the need of pre-treatment by roasting or other methods. In the Los Filos area, known mineralization is associated with early-Tertiary Los Filos and Bermejal–Guadalupe granodiorite stocks that were emplaced into the host carbonate rocks. Mineralization mined in the Los Filos Open Pit is associated with a shallowly east-dipping diorite sill and with the upper portion of the eastern stock. The Los Filos Underground is divided into the Los Filos North (Norte) and South (Sur) sectors along the north and south sides of both the western and eastern stocks. The principal mining areas in the North sector are Nukay and Peninsular, and in the South sector are Independencia and Sur. Mineralization in the Bermejal–Guadalupe area occurs along the contact of the Bermejal–Guadalupe stock with the carbonate rocks of the Morelos Formation. The Bermejal Open Pit mineralization is typically at the top or on the flanks of the upper portion of the intrusive. On the northern end of the stock, mineralization extends below the Bermejal Open Pit and down the steeply dipping to vertical flanks of the intrusion, and is referred to as the Bermejal Underground deposit. The total circumference of the Los Filos stocks is approximately 8 km, with at least half of this circumference tested by drilling or with mining development. The Bermejal–Guadalupe stock has a circumference of approximately 16 km, and although the contacts along the upper portion of the intrusion have been mined by open pit, only a few kilometres of this contact have been explored at depth. Mineralization extends from surface to over 700 m deep, and is variable in grade and width. Additional exploration targets are present along the intrusion contacts in both the Los Filos and Bermejal–Guadalupe areas.

Annual Information Form - 47 - Mineralization on the Los Filos Mine Complex property is typical of intrusion-related gold–silver iron-oxide skarn deposits. Gold skarns typically form in orogenic belts at convergent plate margins and are related to plutonism associated with the development of oceanic island arcs or back arcs. Skarns develop in sedimentary carbonate rocks, calcareous clastic rocks, volcaniclastic rocks, or (rarely) volcanic flows. They are commonly related to intrusion of the sediments by high- to intermediate-level stocks, sills, and dykes of gabbro, diorite, quartz diorite, or granodiorite composition. Skarns are classified as calcic or magnesian types; the calcic subtype is further subdivided into pyroxene, epidote, or garnet-rich members. These contrasting mineral assemblages reflect differences in the host rock lithologies, as well as the oxidation and sulphidation conditions in which the skarns developed, as further described in the Los Filos Technical Report. Mineralization frequently displays strong stratigraphic and structural controls. Deposits can form along sill–dyke intersections, sill–fault contacts, bedding–fault intersections, fold axes, and permeable faults or tension zones. In the pyroxene-rich and epidote-rich types, mineralization commonly develops in the more distal portions of the alteration envelopes. In some districts, assemblages of reduced, iron-rich intrusions can be spatially related to gold–skarn mineralization. Mineralization in the garnet-rich gold skarns tends to lie more proximal to the intrusions. The deposits of the Los Filos Mine Complex are considered examples of calcic-type skarns and display all three subtypes of skarns described above, depending on depth in the system and host rock. All the deposits are genetically related to porphyritic diorites, tonalites, and granodiorites, as well as the hydrothermal system that accompanied intrusive emplacement. Mineralization is either hosted by, or spatially associated with, marble formed during contact metamorphism of the carbonates. Massive magnetite, hematite, goethite, and jasperoidal silica, with minor associated pyrite, pyrrhotite, chalcopyrite, and native gold, typically occur in the veins and metasomatic replacement bodies that developed at the contacts between the platform carbonates and intrusive rocks. Extensive, deep oxidation of the deposits (that occurred at the time of mineralization) has altered the mineralization into material that is amenable to cyanidation recovery techniques without the need of pre-treatment by roasting or other methods. Exploration Equinox Gold and previous companies have undertaken exploration at the Los Filos Mine Complex with a focus on the granodiorite/carbonate contacts in the Los Filos and Bermejal–Guadalupe areas. Exploration activities have included regional and detail mapping; rock and soil sampling; trenching; channel sampling; reverse-circulation (RC) and diamond drilling; ground induced polarization, ground magnetic, and aeromagnetic geophysical surveys; mineralization characterization studies; LiDAR surveys; and metallurgical testing of samples. In March 2022, Eagle Mapping group of Vancouver collected LiDAR and aerial photography surveys of the Los Filos property at a minimum density of 8 ppm with LiDAR accuracies of 15 cm (vertical) and 30 cm (horizontal). Aerial photography was orthorectified to the LiDAR model producing an orthophoto with 15 cm pixel resolution, a digital elevation model (DEM), a digital surface model (DSM), and contour data. The area covered by the surveys includes all concessions of the Los Filos Mine Complex property. Surface mapping and sampling, geochemical surveys, and magnetic surveys highlight the intrusions and related alteration products of contact metamorphism relative to the host carbonate rocks. These alteration zones can host gold skarn mineralization, which requires drilling to delineate.

Annual Information Form - 48 - Drilling From 2003 to June 30, 2022, 939,782 m of diamond and RC drilling have been completed at the Los Filos Mine Complex, including 64,930 m since 2019. This includes drilling for open pit and underground targets at the Los Filos Open Pit, Bermejal Open Pit, Bermejal Underground, Guadalupe, San Pablo, and Xochipala areas and the underground drilling programs in the Los Filos North and South sectors. Drilling since 2019 has focused on extending mineralization in the Bermejal–Guadalupe open pits, Bermejal Underground, Los Filos Open Pit, and Los Filos Underground. Three contractors have completed drilling since 2019, using 13 different drill rigs. Intersection spacing across the deposits that were drilled from surface is approximately 35 x 35 m in areas with closely spaced drilling and widens to about 70 x 70 m in the areas that are less well drilled. Drill spacing is wider again (i.e., 100 x 100 m) in the areas outside the conceptual pit outlines that are used to constrain Mineral Resources. Drill-hole azimuths depend on the orientation of the deposit being drilled. Dips range from 65° to 90° and are commonly 90° for drilling related to the open pit mineralization. For the Bermejal Underground deposit, the drill azimuth varies due to the arcuate shape of the deposit’s strike. The primary azimuths are usually 60° and 180° for the eastern and central portions of the deposit, respectively, whereas the drill holes on the western sector were vertical to provide an intersection angle that is close to perpendicular to the sub-sill mineralization. In the opinion of the responsible Qualified Person, the quantity, quality, and spacing of the lithological, geotechnical, collar survey, and downhole survey data collected in the exploration and infill drill programs are sufficient to support Mineral Resource and Mineral Reserve estimation. Sampling, Analysis and Data Verification Geological logging data for the Los Filos Mine Complex is recorded on tablet computers directly into an acQuire™ database. Sample and assay data are uploaded digitally. Survey data is imported or uploaded from the survey instruments. All drill core samples for exploration and resource estimation are sent to an external laboratory for sample preparation (ALS Chemex, Guadalajara, Mexico) and assaying (ALS Chemex, Vancouver, B.C.). No RC samples were collected from drilling programs in 2017. From 2018 to the present, RC samples have been collected from drilling programs in the Bermejal-Guadalupe Open Pit and Los Filos Open Pit. Drill cuttings from previous RC drilling at the Los Filos Mine Complex were sampled at intervals of 1.52 m. The material was split at the drill into several portions of 12 kg or less. Of these, a 300 g “assay split” was shipped to the external laboratory, and the “second split” was stored on the property. Drill cuttings from RC drilling prior to 2017 at the Bermejal deposit were sampled dry at 2 m intervals. The samples were then transferred to the core facility, then riffle split in three cycles until a 10 kg sample was obtained. The split sample was then bagged and tagged and sent to the sample preparation laboratory (at that time the laboratories used were the San Luis Potosi facility of Bondar Clegg and the Hermosillo location of Skyline Laboratories). For RC samples collected in 2018–2022, drill cuttings were sampled dry at 2 m intervals. All the cuttings were collected in high-strength plastic bags that were previously marked, then weighed to determine the recovery for the interval. The bags were then transferred to the core facility, then riffle split in three cycles until a 6 kg sample was obtained. The split sample was then bagged and tagged and sent to the sample preparation laboratory (ALS Chemex, Guadalajara). The remainder of the RC sample was saved in high-strength bags and stored on site.

Annual Information Form - 49 - Since 2003, core samples for exploration and infill drill programs were either split or cut depending on the hardness or competency of the mineralized material. Splitting was conducted manually with a spatula or putty knife or split with a HYDRASPLIT manual hydraulic splitter. Core cutting was conducted with 220 V Rockman saws, and the core was cut in half along the core axis. The splitting or cutting takes lithological contacts into account, as determined by the geologist during sample interval selection. Samples are usually shorter than 1.5 m, with a minimum sample length of 0.3 m and a maximum of 3 m. HQ and NQ core is split or cut in half. Half of the core is sent for sample preparation and analysis, and the remaining half is retained in the core box. Splitting or cutting core for metallurgical samples usually involves a larger proportion of the core being sent for analysis (75%), with the rest retained in the core box (typically using PQ size core). Once the samples are cut or split, they are bagged and numbered in polyethylene bags. Quality control and quality assurance (QA/QC) samples are added to the sampling sequence prior to packaging sample bags for shipment. The following procedures are applied by ALS Chemex, Guadalajara, Mexico to core samples that are sent to the preparation laboratory, with every fiftieth sample screen-tested to check that the below standards of crushing and pulverizing are being achieved: • Checking samples received against the manifest of the samples that were sent from the Los Filos Mine Complex; • Weighing the sample as received and entering it into the Laboratory Information Management System; • Drying sample for 12 hours (oven dry at 105°C); • Crushing sample to P100 2 mm; • Splitting sample to produce a 1.5 kg split and a reject sample; and • Pulverizing sample to P85 75 µm in a ring and puck pulverizer. All samples from the current drilling programs are analyzed for gold using a standard 50 g fire assay with gold detection by flame atomic absorption spectrometry to a 0.01 ppm detection limit. Multi-element analyses are completed using a multi-acid digest method and an induced coupled plasma optical emission spectrometry finish on 36 elements. The core facility at the Los Filos Mine Complex is within a secure and monitored area on the mine property, and samples are always attended or locked at the sample collection and dispatch facility. Core boxes are transported to the core facility by the drilling contractors. Los Filos mine exploration department personnel undertake sample collection and transportation on site. Independent laboratory personnel using their company vehicles transport samples to the preparation laboratory. The sample preparation and analytical laboratory are independent of Equinox Gold. Chain-of-custody procedures consist of filling out sample submittal forms that are sent to the laboratory with sample shipments, to make certain the preparation laboratory receives all samples. A QA/QC program is in use by the Los Filos Mine Complex exploration department and the independent laboratory also maintains its own QA/QC program to monitor the performance, accuracy and precision of the laboratory analyses. The Los Filos exploration department has a standard QA/QC program in place for all drill core and RC sampling, and also underground mine sampling. The QA/QC program for samples from drilling includes routine insertion of duplicate samples, blank samples, and standards (certified reference materials) and also check-assaying of a suite of samples at an external third-party laboratory.

Annual Information Form - 50 - Assays are received from ALS Chemex as a CSV file. While importing the assays into the acQuire™ database, the software checks the duplicate, blank, and standard samples to determine if they are within the accepted ranges. In the event of a failure, the laboratory is asked to reanalyze the batch of samples that contain the control sample outside the accepted range. Once the re-assays for the batch of samples are received, and if the control sample is within the accepted range, the assays are imported to acQuire™. Los Filos Mine Complex geologists routinely perform validation checks on data, including checks on drill hole surveys, collar coordinates, lithology data, and assay data. Equinox Gold corporate staff completed an additional validation, which included checking coordinates of drill hole collars in the field and reviewing approximately 5% of data collected since 2004. Previous operators conducted and documented validation of drill holes completed prior to 2004. No significant errors or omissions were identified with the database following these checks. In the responsible Qualified Person’s opinion, the sampling, sample preparation, security, and analytical methods in use are acceptable and meet industry-standard practices. In the opinion of the responsible Qualified Person, the data have also been verified, and are therefore adequate for Mineral Resource and Mineral Reserve estimation, and mine planning purposes. Mineral Processing and Metallurgical Testing Extensive metallurgical testwork on samples from the various deposits that comprise the Los Filos Mine Complex has been conducted over the past two decades. Los Filos Open Pit uses geometallurgical domains for defining ore types, whereas Los Filos Underground, Bermejal Open Pit, Bermejal Underground, and Guadalupe Open Pit use rock-type domains for defining ore types. The metallurgical test programs performed prior to 2016 were focused on validating the predicted recovery formulas for heap leaching Los Filos Open Pit and Los Filos Underground and Bermejal Open Pit that were created by Simon Hille (Leach Inc.). Metallurgical test programs performed during or after 2016 started to focus on the potential of using CIL to recover gold from ore that contained greater than 1% total sulphur, mainly from Bermejal Open Pit, Bermejal Underground and Guadalupe Open Pit ore sources. The metallurgical testwork prior to 2016 focused on determining heap leach gold recovery and heap leach engineering design, and the metallurgical testwork has been performed exclusively by Kappes, Cassiday & Associates (KCA) of Reno, Nevada, U.S. Simon Hille conducted an evaluation of heap leach gold recoveries early in 2005, and the results were incorporated into the projection of gold recoveries based on testwork KCA performed in 1998 and 2004/2005, as well as McClelland Laboratories Inc. Simon Hille’s evaluation created a predicted gold recovery model for each ore type and for run of mine (ROM) and Crushed material and the model was applied to Los Filos Open Pit, Los Filos Underground, and Bermejal Open Pit ore sources. Simon Hille’s predicted gold recovery model, derived in 2005, has been validated by the testwork performed from 2005 to 2016. Several metallurgical testwork programs were completed on Bermejal Underground and Guadalupe Open Pit ores after 2015. The Bermejal Underground metallurgical testwork program focused on comparing heap leach gold recovery to CIL gold recovery and supporting CIL engineering design. The metal recoveries for gold and silver are based on historical metallurgical testing of the various deposits for heap leaching and recent testwork for CIL processing. Recoveries and associated processing costs vary depending on rock type, copper and sulphur content as well as processing route, as shown in Table 1 and Table 2.

BCST = base CIL operating cost = $8.62/t of ore. Multi-element analyses of all drill core samples and detailed assaying of a large number of metallurgical test samples indicate that the Mineral Resources at Los Filos Open Pit and Los Filos Underground contain no significant concentrations of deleterious elements, and are amenable to heap leach gold recovery. However, some areas of the Bermejal Open Pit, Guadalupe Open Pit, and Bermejal Underground deposits contain high sulphur and copper levels. Gold recovery has been found to decrease with increasing sulphur levels in the ore, and cyanide consumption has been found to increase with increasing copper levels in the ore. The majority of mineralization at Los Filos Open Pit and Los Filos Underground is Oxide with low sulphur values, and is amenable to heap leach recovery of the gold. Mineral Resources containing over 1.0% total sulphur have been historically excluded from Mineral Reserves and were stockpiled separately from the waste dumps. With the addition of the CIL plant, higher-sulphur-content ores are able to be mined and processed, which provides greater flexibility for ore sourced from the Bermejal Open Pit, Guadalupe Open Pit, and Bermejal Underground ore sources, all of which contain higher sulphur contents than typically encountered in the Los Filos Open Pit and Los Filos Underground ore sources. Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimates Equinox Gold personnel prepared Mineral Resource estimates for the Los Filos, Bermejal, and Guadalupe Open Pits, and the Los Filos and Bermejal Underground deposits with an effective date of June 30, 2022. Mineral Resources are depleted to June 30, 2022, and reported exclusive of Mineral Reserves are as follows:

Mineral Resources that are not Mineral Reserves do not have a demonstrated economic viability. Mineral Resources are reported to a gold price of $1,550/oz and a silver price of $18/oz. Open pit Mineral Resources are defined within pit shells that use variable mining and recovery estimates depending on the geometallurgical domain and whether mineralization is projected to report to crush–leach, run-of-mine or CIL for processing requirements. Open pit Mineral Resources are reported to a gold cut-off grade of 0.2 g/t. Open pit Mineral Resources use variable mining costs of $1.27–$1.43/t and variable processing costs of $3.40–$12.81/t. Recovery ranges from 50% to 85% depending on ore treatment method. Underground Mineral Resources use variable mining costs of $57.21–$93.12/t and variable processing costs of $9.53–$11.64/t, and a process recovery of 90%–95%. Underground Mineral Resources are reported to a gold cut-off grade of: 1.71 g/t Au for Los Filos South Underground; 2.05 g/t Au for Los Filos North Underground; 2.71 g/t Au for Bermejal underground. Quantity of material is rounded to the nearest 1,000 tonnes; grades are rounded to two decimal places for Au, one decimal place for Ag; rounding as required by reporting guidelines may result in apparent summation differences. The Qualified Person responsible for the Mineral Resource estimate is Ali Shahkar (P.Eng.). Block model quantities and grade estimates for the Los Filos and Bermejal–Guadalupe deposits were classified according to the CIM Definition Standards for Mineral Resources and Mineral Reserves (CIM, 2014). Mineral Resource classification is subjective and depends on the experience of the Qualified Person and their confidence in the geological and grade continuity of mineralization, confidence in the quality, quantity, and distribution of data supporting the estimates, and the geostatistical confidence in the resource estimates. Classification should delineate regular areas at a similar resource classification.

Annual Information Form - 54 - The responsible Qualified Person is satisfied that the geological modelling accurately reflects the available geological information and knowledge at a scale appropriate for the mining methods considered. The sample locations and assay data, which include samples from core and RC drilling, and underground channels, are sufficiently reliable to support resource evaluation. Mining at the Los Filos Mine Complex is conducted by both open pit and underground methods, on two separate and complex deposits. As such, the confidence in geological and grade continuity, and the data spacing required for classification as Measured Mineral Resources (within the meaning of NI 43-101) and Indicated Mineral Resources (within the meaning of NI 43-101) (and therefore sufficient for mine planning) varies depending on both the mining method and the detailed nature of the deposits. Classification at Los Filos is primarily based on search distances from data (drill holes and in some cases channel samples). Bermejal–Guadalupe Open Pit and Bermejal Underground models did not use hard boundaries for classification (distance searches were allowed to cross geological boundaries), whereas at Los Filos Open Pit and Los Filos Underground, due to more irregular data spacing in some geological domains, classification used hard boundaries for the three main domain types (Oxide, Granodiorite, and Carbonate). The Bermejal–Guadalupe Open Pit model considered Guadalupe underground channel samples for Indicated and Inferred Mineral Resource (within the meaning of NI 43-101) classification, but not Measured. Channel samples were considered for classification in the Los Filos Underground models, but not the Los Filos Open Pit or Bermejal Underground models. A small resource area within the Bermejal–Guadalupe Open Pit model known as the 7 Vetas area was assigned only Inferred classification. In the Bermejal Underground model, all blocks within Carbonate (domain numbers 60, 61, and 62) are set as Inferred Mineral Resources. There are no known environmental, permitting, socioeconomic, legal, title, taxation, marketing, political, or other relevant factors that could materially affect the Mineral Resource estimate. Estimating Mineral Resources is not without risks: factors such as additional drilling and sampling may affect the geological interpretation, the conceptual pit shells, or the underground mining assumptions. Other factors that may have a positive or negative impact on the estimated Mineral Resources include the following: gold and silver price assumptions; changes in interpretations of lithological, mineralization, or geometallurgical domains; pit slope angles for the open pits or geotechnical assumptions for underground stope designs; changes to the methodology used to assign densities in the resource models; changes to the assumptions used to generate the gold cut-off grades for resource declaration; changes to the parameters used for grade estimation; and changes to the classification criteria used. Mineral Reserve Estimates Mineral Reserves are reported in accordance with NI 43-101, CIM (2014) definitions. Modifying factors were applied to convert Mineral Resources to Mineral Reserves, including mining cut-off grades, mining dilution, and mining recovery factors. Only Measured and Indicated Mineral Resources are used to state Mineral Reserves. The consolidated open pit and underground Mineral Reserve estimate based on Proven Mineral Reserves (within the meaning of NI 43-101) and Probable Mineral Reserves (within the meaning of NI 43-101) for Los Filos is presented in Table 4.

Mineral Reserves are estimated using a long-term gold price of $1,450 per troy oz and a long-term silver price of $18 per troy oz for all mining areas. Mineral Reserves are stated in terms of delivered tonnes and grade, before process recovery. Mineral Reserves are defined by pit optimization and are based on variable break-even cut-offs as generated by process destination and metallurgical recoveries. Metal recoveries are variable dependent on metal head grades. Open pit dilution is applied at: a. 5% at a zero grade for Au and Ag for Bermejal Open Pit and Guadalupe Open Pit, and b. 7% at zero grade for Au and Ag for Los Filos Open Pit. Open pit mining recovery is applied at: a. 95% for Bermejal Open Pit and Guadalupe Open Pit, and b. 93% for Los Filos Open Pit. Heap leach process recovery varies based on rock type. Effective date of Mineral Reserves is June 30, 2022. Tonnage and grade measurements are in metric units. Contained Au and Ag ounces are reported as troy ounces. Underground Mineral Reserves are reported based on a variable net processing return cut-off value varying between $65.80 and $96.60/t Underground dilution is assigned an average of 10% at a zero grade for Au and Ag. Underground mining recovery is set to 97%. Numbers may not sum due to rounding. The Qualified Person for the open pit estimate is Mr. Eugene Tucker, P.Eng., and for the underground estimate is Mr. Paul Salmenmaki, P.Eng. The metal recoveries for gold and silver are based on historical metallurgical testing of the various deposits for heap leaching as well as recent testwork for CIL processing. Metal recoveries for gold and silver and associated processing costs vary depending on rock type, copper (Cu) and sulphur (S) content, and processing route. Pit optimizations were performed using the Lerchs–Grossmann algorithm to define economically mineable shapes using an open pit mining method. Two pit optimization scenarios were analyzed to define the optimum mining shapes to use as the basis for pit designs; the first scenario incorporated the G&A costs in the cost structure used for pit optimization (G&A included), whereas the second scenario omitted the latter costs (G&A excluded). The two scenarios were used to evaluate the impact of fixed costs on pit phase selection for inclusion into the mine plan, due to excess processing capacity at stages of the mine life. Pit phases were designed based on the selected optimized pit shells for the two scenarios and by taking into account geotechnical parameters and operational constraints. Topographic surveys as of June 30, 2022, were used to deplete the open pit mines. Open pit mining ore loss and dilution parameters were assessed based on operational practices and reconciliations between the block model and production actuals. Based on these reconciliations and expected future mining conditions mining loss and dilution for the Los Filos Open Pit pit area were both estimated at 7%. For the Bermejal Open Pit and Guadalupe Open Pit pit areas mining loss and dilution were estimated at 5%.

Annual Information Form - 56 - Inputs to the optimization process include slope angles, metallurgical recoveries, operating costs, selling costs, and government royalties. Mining operating costs are based on historical costs and first principles estimates. An incremental haulage cost increase of approximately $0.02/t per bench was applied to material mined from benches that are above or below the reference bench elevation, which is the bench elevation at which haul trucks exit each pit. Mining costs vary by destination due to variable surface haulage distances to the respective destination. The economic cut-off varies based on the metallurgical recovery and operating cost assigned to each mined block. The metallurgical recovery for each block varies based on the rock type, sulphur content, and the processing destination (crushed heap leach, ROM heap leach or CIL). The operating cost for each block varies based on the mining, processing, and G&A cost. The mining cost is dependent on the haulage distance to the processing destination. The Qualified Persons responsible for the Mineral Reserve estimates are not aware of any mining, metallurgical, infrastructure, permitting or other relevant factors that could materially affect the Mineral Reserve estimates. Factors that may affect the Mineral Reserve estimates include the following: commodity prices; mining recovery and metallurgical recovery assumptions; presence of unexpected quantities of copper or sulphur, which may impact economical treatment of ore at the process plant or heap leach facility; methodology of assigning ore densities; geotechnical characteristics of the rock mass; excess underground mining dilution; and ability to consistently deliver the required process plant feed to the process plant. Mining Operations Underground Mining The current mining methods for Los Filos Underground are overhand cut and fill in the narrow areas and overhand drift and fill in the wider areas. Both are proven methods at Los Filos Underground and allow for a high degree of selectivity. The longhole open stoping mining method is also used in targeted areas of vertical ore body continuity and good rock conditions. The mining method used for Bermejal Underground is overhand drift and fill in oxide ore, which constitutes most of the deposit, and underhand drift and fill to mine ore in intrusive host rock. Based on the selective nature of the predominant cut-and-fill mining method, AMC anticipates that good mining practices will allow mining dilution to stabilize around 10% and mining recovery at 97%. Underground ore is sent to the heap leach crushed processing route until the CIL plant is expected to become available in mid-2024. The cut-off values supporting the estimation of underground Mineral Reserves were developed as a net processing return for Bermejal Underground, as the processing cost and metallurgical recovery to the CIL plant are variable. With respect to Los Filos Underground, the cut-off grade was determined based on a fixed processing cost and metallurgical recovery based on the average grade over the remaining mine life. The mining operations are contracted out at Bermejal Underground and Los Filos Underground South; the Los Filos Underground North mine is owner-operated. Los Filos Underground is extracting ore from two main zones, Nukay and Peninsular. The mine is expected to produce approximately 1.2 Mt of ore at an average production rate of 960 t/d, until the end of its life in 2025. For Bermejal Underground, access to the ore zones is via the East portal. A second portal, the West portal, is planned to provide a second access by 2025. Once the second portal is completed, mining is planned to operate at a steady-state production rate of 1 Mt/a from 2025 to 2032.

Annual Information Form - 57 - Open Pit Mining Open pit mining will remain owner-operated with conventional load, haul, drill and blast on 9 m benches. Loading is undertaken by 250-tonne shovels and large front-end loaders, and haulage by 136-tonne trucks. A larger mining fleet composed mainly of 180-tonne electric-drive trucks and 400-tonne face shovels is proposed to progressively replace the existing mining equipment as it reaches the end of its useful life. Ore (Crushed) is hauled either to the crusher, for crushed heap leach, or directly to an ROM leach pad for processing. A 10,000 t/d CIL processing plant is planned to be constructed to offer an alternative processing destination starting in Q3 2024. Waste is hauled to external or in pit waste rock dumps. Mathematical equations were used to derive the metallurgical recovery and processing costs for each mining block based on rock type, sulphur, gold, and copper content, and the processing destination (crushed or ROM heap leach, or CIL). An allowance for mining dilution and mining recovery was used based on historical performance and reconciliation of the resource model to the mining production. Mining dilution and ore loss at Los Filos Open Pit is estimated at 7% and at 5% at the Bermejal and Guadalupe Open Pits. These inputs, combined with mining costs, general and administrative costs, selling costs, metal prices, and royalties, were used to derive economic open pit cut-off grades. The ultimate open pits were designed based on guidance from pit optimization, geotechnical parameters, and practical constraints. A combination of external waste dumps and in-pit backfills was used to minimize haul distance for the waste rock mined. Combined Schedule The combined open pit and underground mine plan aimed at optimizing project value by allocating ore to the most attractive processing destination, based on mining and processing constraints, operating costs (OPEX), revenue, and capital costs (CAPEX) considerations. The combined mine plan results in an estimated mine life that extends until 2036. The resulting ore and gold production is presented in Table 5.

Annual Information Form - 59 - Processing and Recovery Operations Heap Leach Process Two large geosynthetic-lined heap leach pads are in operation, both of which have been divided into two sections: one for Crushed ore and the other for ROM ore. ROM ore is stacked on Pad 1 and Crushed ore on Pad 2. Pads 1 and 2 cover 2,515,000 m2 and 721,000 m², respectively, for a total area of 3,236,000 m2. A simplified processing flowsheet of the heap leach process is shown on Figure 1. Source: Equinox Gold. Figure 1: Simplified Los Filos Processing Flowsheet The Adsorption-Desorption-Recovery (ADR) plant is a conventional carbon-in-column adsorption facility associated with an elution circuit, carbon regeneration circuit and gold refinery that produces a gold–silver doré product. The ADR plant is used to recover all heap leached gold. Three re-leaching programs have been instrumental in reducing the gold-recoverable inventory to 52 koz by June 30, 2022. The re-leaching programs were completed by the end of 2021. Equinox Gold reported the 2021 ending inventory to be 66 koz. Equinox Gold estimates that 14 koz of gold will be recovered in 2022 from ore stacked in Q4 2021. Ore stacked in Q1 & Q2 2022 is fully leached after 120 days for Crushed and 180 days for ROM ores. Depending on where the stacked ore is in the leaching cycle, it is estimated that 49 koz of recoverable gold will be recovered in Q3 2022 from the ore stacked in Q1 and Q2 2022. The remaining recoverable inventory in the heaps will be 17 koz.

Annual Information Form - 60 - Recovery factors estimated for the various ore sources to heap leaching process are based on appropriate metallurgical testwork, and these have been confirmed by recent production data. CIL Process The CIL plant design is based on a robust metallurgical flowsheet developed for optimum recovery, while minimizing CAPEX and OPEX. As the CIL plant is an addition to an existing operation, existing site services (power, water, etc.) will be used, where appropriate, to supply the new facilities. The process of the new CIL plant includes crushing, milling, gravity, carbon in leach, carbon regeneration, thickening, and filtration of the CIL tailings for dry-stack storage. The plant design is considered appropriate for a project with an expected 12.5-year operating life. The key project design criteria for the CIL plant are: • Capacity to treat 10 kt/d (3.65 Mt/a) of varying blends of the ore types as determined by the integrated LOM production schedule. • Crushing plant utilization of 75% and CIL and tailings filtration plant utilization of 91.3%, supported by the incorporation of surge capacity and standby equipment, where required. • The grinding plant will grind ores to P80 0.075 mm and leach them in a CIL circuit for 40 hours to extract an estimated 90.6% contained gold and 38.8% contained silver. • The grinding flowsheet includes gravity concentration. • Gold will be recovered from the loaded carbon in a 10-tonne batch ADR plant. • CIL plant tailings will be thickened, filtered, and delivered by conveyors to the heap leach pad for stacking. • Sufficient automation and plant control will be incorporated to minimize the need for continuous operator intervention, but will allow manual override and control if and when required. • There are sufficient testwork and other data to support the gold and silver recovery estimates used for all material scheduled to be fed to the proposed CIL plant. CIL design documents have been prepared and incorporate engineering and key metallurgical design criteria derived from the results of historical and recent metallurgical testwork programs. At the time of completing the Los Filos Technical Report Equinox Gold has not made a construction decision for the CIL plant. Infrastructure, Permitting and Compliance Activities Infrastructure Major infrastructure at Los Filos includes: thirteen waste rock dumps, including in-pit waste dumps at Los Filos and Bermejal Open Pits; primary and secondary crushing plants (up to 25,000 t/d capacity); overland conveyors; agglomerator with cement and lime silos; two pregnant solution collection ponds (one for each heap), one recirculation pond, and two contingency water ponds; and ADR plant and gold refinery. Support facilities on the property include: access roads; haul roads from mining areas to waste dumps, crusher, and leach pads; open pit truck and equipment shop; underground equipment shops; welding shop; warehouse; administrative office facilities; underground offices (on surface); underground mine dry (change house); underground mine compressors; drill core logging and storage facilities; metallurgical laboratory; fire assay and atomic absorption assay laboratory; explosive storage facilities; power distribution facilities; fuel storage facilities; water distribution facilities; personnel training facilities; environmental monitoring facilities; and an airstrip (1,200 m long paved strip). Additional infrastructure that is not directly at the Los Filos Mine Complex, but is nearby, are a power substation, water supply line and pumping stations and the residential camp.

Annual Information Form - 61 - Approximately 260 Mt of ore have been stacked on the heap leach pads. There is sufficient storage capacity for the LOM Crushed ore on Pad 2; however, Pad 1 will not have enough storage capacity to store all the LOM ROM ore. A third pad (Pad 3) will be constructed at the southern end of Pad 2 to provide 63.5 Mt of additional storage for ROM. This new pad will be constructed in three phases, starting with the first phase in 2023. In addition, an “interliner” is proposed to be constructed on top of portions of Pads 1, 2, and 3 once the pads have been filled to their design capacity. The interliner will provide up to 60 Mt of additional storage capacity for ROM ore. The interliner will be built in two phases, with the first phase required by Q1 2031 and the second phase by Q4 2032. The current and planned heap leach pad infrastructure will be sufficient to support mining operations for the LOM plan. A total of 45.7 Mt of tailings will be generated from fine grinding the various ores during the CIL process. The tailings will be filtered through a series of pressure filter presses to achieve a high degree of dewatering, with the resultant tailings cake disposed in a filtered tailings storage facility on the eastern side of Pad 1 and close to the planned tailings filter plant. The filtered tailings will be transported from the tailings filter plant to the deposition area by mobile grasshopper conveyors and deposited with a radial stacker. The filtered tailings storage facility will be developed in phases, and the first phase is expected to be prepared by mid-2024 when the CIL plant and tailings filter plant are commissioned. New waste rock facilities (WRFs) are proposed, which will partially or completely overlap the existing facilities, including the in-pit WRFs. Detailed stability analyses for these facilities will have to be completed in the next stages of design. These analyses may require foundation or waste material characterization. The CIL plant will consume additional energy beyond the capacity of the existing substation; therefore, a larger, 40 MW substation is proposed to provide electrical energy to the expanded mine. An application was made to CENACE (Mexico’s federal electricity commission utility) for the additional energy required, and CENACE completed a study to confirm energy availability and electrical infrastructure upgrades. The study will be updated once a final decision to advance the CIL plant is made. Permitting and Compliance Activities The existing operational permits for the Los Filos Mine Complex were granted based on the environmental impact assessments and land-use change technical submittals. The authorizations included approval of mitigation measures proposed by DMSL in compensation of potential environmental impacts and a monitoring program to identify any impacts from operations. DMSL holds the appropriate permits under local, state, and federal laws to allow the current mining operations. The environmental permit (MIA) for the CIL plant and associated infrastructure was granted in August 2018 and 2021. The permits to construct the new electrical substation and extension of the high voltage transmission line will require updating as the location of the substation has been modified since the MIA process. For the filtered tailings disposal from the CIL plant, DMSL applied for a MIA to construct and operate a filtered tailings storage facility on top of Pad 1, and the MIA was granted in 2018; however, the volume and preferred location of the filtered tailings storage facility was subsequently modified, and therefore the current permit will need to be modified accordingly. The responsible Qualified Person is of the opinion that these modifications will be granted. The review of the electrical interconnection requirements and the confirmation of energy supply to support the CIL plant was completed with CENACE; however, the studies must be updated once a final decision to advance the CIL plant is made. The permit for the new Pad 3 expansion has been approved; however, permitting of the vertical expansion of Pads 1, 2 and 3 with the interliner must be submitted for approval. Water usage for the Los Filos Mine Complex is 1.0 Mm3/a and the permit allows for 1.2 Mm3 of extraction. An application to increase the water permit to 2.2 Mm3/a is in process and is expected to be approved. The following pending permitting issues are in the process of resolution with the relevant authorities:

Annual Information Form - 62 - • DMSL has received clearances for 53 of the 58 possible archaeological sites identified in the baseline studies. There are five sites restricted from mining operations. • DMSL is applying for a new wastewater discharge permit for the employee camp facilities, as the previous permit has expired. DMSL submitted the application on September 13, 2022. DMSL has a collaborative agreement for social development that provides contributions to the communities in the amount of approximately $3 million annually. In 2020, production was shut down due to a 103 day work stoppage related to a dispute with the ejido of Carrizalillo on their social collaboration agreement. Negotiations took place to modify the existing agreement. DMSL continues working to regain trust between the company and the communities. The existing closure and reclamation plan is conceptual and addresses all existing facilities. The current estimated closure liability of $50.9 million is based on the existing facilities at the end of 2021, and as such is exclusive of the proposed CIL plant, filtered tailings storage facility, new electrical substation and transmission line extension, Pad 3, and the Pads 1 and 2 interliner. The closure and reclamation plan will have to be expanded to include closure methods of these future projects once they are built. Security instability in the State of Guerrero and in the local mine area remains a concern, and could cause temporary closure of operations or disruptions in services. This security risk may also impact the ability of the company to contract and retain skilled, experienced employees. The responsible Qualified Person is not aware of any significant risk or uncertainty that may materially affect the reliability or confidence in the Mineral Resource or Mineral Reserve estimates or project economic outcomes due to the environmental permits. Risks that may impact current or future operations have been identified to include the following: • Guadalupe Open Pit will require clearance from Instituto Nacional de Antropologia e Historia (National Institute of Anthropology and History) of three archeological ruins identified in the area. A further study and salvage program is expected to be carried out in 2023. • Renegotiation of land access to community property in 2024 and 2025 with the communities of Mezcala and Carrizalillo, respectively. Continued access to properties not owned by DMSL is a potential risk. In particular, ejidos may have frequent changes in the directors, and new management may want to renegotiate existing agreements. As part of the Los Filos activities, DMSL reduces potential risk to exploration and mining through long term surface access agreements and proactive communications.

Annual Information Form - 63 - Current Capital and Operating Costs The following information provides a summary of activities and expenditures completed in 2023 and the Company’s forecasts for 2024 for Los Filos. Capital Cost Estimates The table below presents the 2023 capital costs and the 2024 budgeted capital costs. Table 4: Capital Costs Description 2023 Costs ($ million) 2024 Budget ($ million) Capitalized stripping & mine development 12.9 23.8 Infrastructure & equipment 18.4 17.4 Exploration 2.7 5.5 Reclamation & rehabilitation 3.0 3.3 Total 37.0 50.0 Notes: 1. Totals may not add due to rounding. 2. Capital costs include capitalized exploration expenditures, reclamation & rehabilitation costs, and lease payments for haul trucks and mining equipment. The capital expenditures include sustaining expenditures for mining, processing and general and administration costs and non-sustaining expenditures. Operating Cost Estimates The table below presents the 2023 operating costs and the 2024 budgeted operating costs. Table 5: Operating Costs Description Units 2023 Costs ($) 2024 Budget ($) Mining open pit US$/t mined 2.08 1.88 Mining Underground US$/t mined 117.81 113.63 Processing US$/t processed 10.14 9.28 Site General US$/t processed 4.02 4.22 Notes: 1. Totals may not add due to rounding. 2. Operating costs include all mining, processing and general and administration costs including waste stripping. 3. Costs are variable depending on whether ore mined and milled is classified as oxide, transitionary or fresh rock. Costs are based on whether the material being processed is stockpiled or in situ material. Cost estimates in the tables above are based on the Los Filos mine plan and Equinox Gold’s current estimates as of December 31, 2023. Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates and changes to current mining operations or the mine plan. The current mine plan is based on existing Mineral Reserves. Ongoing exploration and analyses at operating mines are conducted with a view to identifying new Mineral Resources and upgrading existing Mineral Resources to higher confidence levels and potentially into new Mineral Reserves. If new Mineral Reserves are successfully identified, it may alter the current mine plan and potentially extend the mine life.

Annual Information Form - 64 - Exploration, Development, and Production Exploration Exploration drilling in 2023 totalled 4,022 m and was focused on the Los Filos open pit area and specifically on the potential conversion of inferred resource material within the short-term mine plan. Planned exploration at Los Filos in 2024 includes approximately 11,000 m of infill and step-out drill programs at the Los Filos and Guadlupe open pits and the Los Filos underground deposits. Development During 2023, sustaining capital expenditures totaled $33.8 million, primarily relating to Guadalupe and Los Filos open pit capitalized stripping and Los Filos underground development. Non-sustaining capital expenditures were $0.7 million. Bermejal underground was suspended on February 22, 2023 to defer development capital until Greenstone construction is complete and to allow time to work on plans to improve productivity and reduce costs. Budgeted 2024 sustaining expenditures at Los Flios of $50 million include $15 million for Bermejal open-pit development, $8 million for Los Filos open-pit development, $5 million for Guadalupe open-pit development, $3 million for Los Filos North underground development, $7 million for processing equipment and $5 million for exploration. There are no non-sustaining expenditures budgeted for Los Filos in 2024. Production Los Filos produced a total of 159,071 ounces of gold during 2023 at cash costs of $1,655 per ounce and AISC of $1,890 per ounce of gold sold. Los Filos production for 2024 is estimated at 155,000 to 175,000 ounces of gold, with cash costs of $1,785 to $1,885 per ounce and AISC of $2,090 to $2,190 per ounce. Los Filos operates as an open pit and underground mining operation with all ore being processed on a heap leach facility. To ensure the long-term viability of the mine and maximize the value of the gold endowment at Los Filos, a carbon-in-leach (CIL) plant is needed to increase gold recovery from higher-grade ore from both underground and open pit deposits. Cost and production guidance for Los Filos is subject to the successful execution of new social and land access agreements with local community stakeholders and landowners. These new agreements are necessary to help ensure the long-term economic and investment viability of the mine, including the addition of a new 10,000 tpd CIL processing plant. If the Company is unable to satisfactorily complete these agreements, the Company will re- evaluate the current operation and may elect to suspend operations, indefinitely or until such time as new agreements are in place. Accordingly, Los Filos production and cost guidance for 2024 is subject to change.

Annual Information Form - 65 - Aurizona Mine Aurizona Gold Mine is an operating open-pit mine and processing plant located in Maranhão State, Brazil that achieved commercial production in Q3 2019. On September 20, 2021, Equinox Gold announced the results of a pre-feasibility study for an expansion at Aurizona. Mining underground and open-pit satellite deposits concurrently with the existing open pit would extend the Aurizona mine life and increase production to on average 137,000 ounces of gold per year. The Company is advancing a feasibility study and permitting for the expansion. Unless otherwise indicated, the information that follows relating to Aurizona is based on, derived substantially from, and in some instances is a direct extract from, the Aurizona Technical Report. Technical information disclosed since the effective date of the Aurizona Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151. The information below is based on assumptions, qualifications and procedures that are set out only in the Aurizona Technical Report and reference should be made to the full text of the Aurizona Technical Report which Equinox Gold has filed under its SEDAR+ profile at www.sedarplus.ca its EDGAR profile at www.sec.gov/EDGAR and which is also available on Equinox Gold’s website at www.equinoxgold.com. Property Description, Location and Access Aurizona is located in the state of Maranhão in northeastern Brazil between the cities of São Luis and Belém. Aurizona is centered at approximately 01°18’ south latitude and 45°45’ west longitude. Year-round road access is available from the state capital cities of Belém, Pará (400 km), and São Luis, Maranhão (320 km), the latter requiring a ferry transfer from São Luis island to the mainland or a longer bypass by road on land. Aurizona includes one active mining license totaling 9,982 ha, one mining license application totaling 5,029 ha, and eleven exploration licenses totaling approximately 92,012 ha for a total land package of approximately 107,023 ha of the eleven exploration licenses. Four of the exploration licenses are in good standing and expire on August 01, 2024 and seven are under application for extension. Two of the seven exploration licenses have Positive Final Exploration Reports from Brazil’s National Mining Agency (ANM). All thirteen licenses are 100% held by Equinox Gold via its wholly owned subsidiaries Mineração Aurizona S.A. (MASA) and Luna Gold Pesquisa Mineral LTDA (Luna Gold). The Piaba and Boa Esperança deposits, as well as several near mine exploration targets, are covered by the mining licence. The mining license application covers Tatajuba; Genipapo and Touro deposits are covered by explorations licences with Positive Final Exploration Reports protocolled with ANM. Equinox Gold, through MASA, owns all surface rights required for the operation of Aurizona. Royalties on Aurizona are held by the Brazilian government and Sandstorm Gold Royalties Ltd. (Sandstorm). The mining license is subject to a government royalty of 1.5% which is applied to gross revenue from sales payable to the Brazilian government. Aurizona is subject to two net smelter return (NSR) royalties (the Aurizona Property NSR and the Greenfields NSR) and a convertible debenture in favour of Sandstorm dated January 3, 2018. The Aurizona Property NSR covers the mining license and the four brownfield exploration licenses including all the Mineral Resource estimates presented in the Aurizona Technical Report, and any future resources from these properties that would be processed through

Annual Information Form - 66 - the Aurizona mill net of third-party refining costs. The Aurizona Property NSR is a sliding scale royalty based on the price of gold as follows: • 3% if the price of gold is less than or equal to $1,500/oz • 4% if the price of gold is between $1,500 and $2,000/oz • 5% if the price of gold is greater than $2,000/oz The Greenfields NSR covers the other seven exploration licences on Aurizona and are subject to a 2% royalty. Sandstorm holds a right of first refusal on any future streams or royalties on the licences covered in the Aurizona Property NSR or Greenfields NSR. Obligations of an exploration license holder to ANM in Brazil include: (1) payment of an Annual Tax per Hectare (TAH) based on the number of hectares held; (2) payment of all expenses related to ANM site inspections of the licensed area; and (3) submission of an exploration work report before the authorization’s expiration date. The 107,023 ha held under license by Equinox Gold equates to an estimated aggregate TAH of R$218,000, which is equivalent to US$43,500. Compliance with these obligations is essential for keeping the mineral licenses in good standing with a failure to meet obligations allowing ANM to impose penalties and possibly cancel the mineral licenses. History In 1978, subsidiary companies of Brascan Recursos Naturais S.A. (Brascan) started exploration programs in alluvium that lasted through to 1985. In 1988 MASA, a subsidiary of Brascan, received a license to mine in what is now the Aurizona mining license. In July 2011, Luna Gold assumed 100% ownership of Aurizona pursuant to a purchase agreement completed in January 2007 with Brascan and Eldorado Gold Corporation. In March 2017, JDL Gold Corp. merged with Luna Gold to form Trek Mining Inc. (Trek) after which Trek merged with NewCastle Gold Ltd. and Anfield Gold Corp. to form Equinox Gold. Production from Aurizona for the period 2010 to 2021 was all from the Piaba deposit. The mine has produced 594,000 oz (recovered) from 16.0 Mt of laterite, saprolite, and transition ore with an average gold grade of 1.31 g/t and overall gold recovery of 89%. Geological Setting, Mineralization and Deposit Types Aurizona mineralization is characterized as a greenstone-hosted orogenic gold system. Mineralization occurs as structurally-controlled gold deposits including the Piaba deposit, which is currently being mined. Piaba, Boa Esperança, Tatajuba and Genipapo deposits are on and adjacent to the Aurizona Shear Zone, a regional northeast- striking structure. Touro is 16 km southwest of the Aurizona mine which hosts gold mineralization within an intrusive unit. These deposits are hosted by Paleoproterozoic volcano-sedimentary and intrusive rocks of the São Luis Craton, an eastern extension of the Guyana Shield which contains several major Proterozoic gold deposits including Las Cristinas, Omai, and Rosebel, extending from Venezuela to Brazil. Aurizona geology is dominated by volcano-sedimentary sequences of the 2.23-2.24 Ga Aurizona Group, and granitoids of the Tromaí Intrusive Suite. The Aurizona Group is comprised of felsic, intermediate, and mafic volcanic and volcaniclastic rocks, as well as metasedimentary rocks. The bedrock units are covered by Phanerozoic sedimentary basin deposits and recent coastal sediments.

Annual Information Form - 67 - Gold mineralization at Piaba and the other deposits is generally associated with subvertical tabular zones of intense shearing and hydrothermal alteration consisting of quartz-carbonate- sericite±chlorite. Quartz±carbonate shear veins are the primary host for gold mineralization with flat to shallow dipping quartz±carbonate extensional veins also carrying gold. Pyrite is the dominant sulphide with lesser arsenopyrite or pyrrhotite, except at Tatajuba and Touro where arsenopyrite mineralization is commonly observed. Native gold is observed within the grey shear veins, commonly occurring along vein margins. An aerially extensive regolith profile has developed across Aurizona with distinct effects on geochemical dispersion and physical properties within each regolith domain type. The regolith profile overprints mineralization and can extend to vertical depths of more than 60 m, and is underlain by fresh, sulphide-bearing rocks that host primary gold mineralization. Exploration Exploration since 2007 has been operated by MASA working out of the Aurizona camp. The exception is the work performed by AngloGold Ashanti Holdings plc (Anglogold) on the regional greenfields joint venture between 2016 and 2018, which was operated by AngloGold personnel. In May 2016, AngloGold entered into earn-in JV agreement on Equinox Gold’s Greenfields Concessions at Aurizona. The JV covered approximately 1,700 km2 of regional exploration ground. Roughly $9M in expenditures was spent on exploration including completion of more than 43,000 line-kilometres of airborne geophysics, approximately 10,000 m of drilling, and soil geochemistry and geologic mapping surveys. In August 2018, the JV was terminated, and Equinox Gold retained its 100% interest in the greenfield concessions. Non-drilling exploration activities at Aurizona are summarized below. Table 1: Summary of Exploration Activities to December 2020 Historic 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 Total Surface Sampling Soil Sampling (samples) 23,484 2,500 3,041 15,142 19,148 9,074 3,408 308 4,176 2,875 682 1,400 85,238 Rock Sampling (samples) 738 13 106 87 171 267 957 151 551 362 23 213 253 8 3,900 Channel Sampling (metres) 128 1,944 231 145 157 97 291 457 3,450 Trenching (metres) 3,187 253 3,440 Geophysical Surveys Airbourne Magnetics/ Radiometrics (line km) 23,908 37,726 61,634 Airborne EM (line km) 5,586 5,586 Ground Magnetics (line km) 50 265 236 249 19 819 IP (line km) 9 34 43 Drilling In 2020, MASA completed drilling on numerous targets including Piaba, Boa Esperança, Genipapo and Touro. A total of 29,543 m of drilling in 65 diamond drill holes (DD) was executed in support of the Piaba underground resource for the pre-feasibility Study. The Boa Esperança deposit was reverse circulation (RC) drilled for grade control purposes with 495 holes for a total of 15,919 m. Additional drilling on the Genipapo and Touro contributed to the datasets that support inaugural resource statements for these deposits.

Annual Information Form - 68 - There are five deposit areas at Aurizona including the Piaba, Boa Esperança, Tatajuba, Genipapo and Touro deposits, which have a total of 178,943 m of drilling in 1,182 holes. The dominant drilling method for the deposit areas was HQ sized, diamond drill holes with a total meterage of 152,049 m in 744 holes. RC was also utilized for 438 holes with 26,896 m. Drilling is typically oriented to the southeast or to the south to intersect steeply dipping, northeast to east-west striking mineralized zones. Grade control drilling in the Piaba open pit and at Boa Esperança is executed with RC drilling methods. There is an additional 26,567 m in 278 holes of regional diamond and RC drilling on Aurizona. Auger drilling has been used to delineate trends and for condemnation in areas of planned site infrastructure. It is the responsible Qualified Person’s opinion that the drilling procedures are adequate to support Mineral Resource estimation. There are no known drilling or sampling factors that could materially impact the accuracy and reliability of the results. Sampling, Analysis and Data Verification Sample Preparation, Analyses, and Security Equinox Gold maintains a Quality Assurance/Quality Control (QA/QC) sampling program, including insertion and review of coarse blanks, certified reference materials (CRM), and duplicates. Blanks, CRMs, and quarter core duplicates are included with routine samples at a 3-4% insertion rate per material type. Sample intervals are a nominal 1 m and range from 0.3 m to 4.0 m length and can cross geological and regolith boundaries. Core is consistently sampled on the same side and the remaining half of the core is stored in the core box for reference. RC samples are collected at the drill rig by the contracted drilling personnel. The entire sample representing a 1 m run length is collected at the drill site. RC samples are not processed or split prior to shipment. Entire RC samples are shipped to the commercial assay laboratory where they are dried and split before analysis. Blanks and CRMs are inserted in a similar manner as with drill core samples. After the cutting and bagging of individual samples, sample shipments are prepared in sealed rice sacks. Sample shipments are transported by a commercial transport company directly from the core facility to the preparation laboratory. The chain of custody procedures includes long term storage of records documenting transport to and receipt of sample shipments at the laboratory. The sample shipments are prepared by MASA staff and have adequate security and tracking measures employed during preparation, packing and transport. Equinox Gold has used ALS Global as its primary independent laboratory since 2008, and ACME Analytical Laboratories Ltd (now Bureau Veritas) in 2007 and late in 2011. A variety of laboratory locations have been used to prepare and assay samples, all of which follow ISO procedures. From 2007 to 2016 all drilling samples were analysed by fire assay with atomic absorption spectroscopy finish and samples returning greater than 10 g/t gold were automatically re-analysed via fire assay with gravimetric finish. In 2017, the procedure was modified to include assay of samples that return greater than 10 g/t gold by screen fire assay to address the presence of coarse gold. The QA/QC materials are appropriately matched to the mineralization at Aurizona. The results are reviewed on a batch by batch basis to monitor the accuracy and precision of the results. A series of rules are followed to audit the QA/QC results and possible failures and subsequent follow up actions are taken as required. The sample preparation, analysis and security procedures demonstrate that the resultant dataset is adequate for use in Mineral Resource estimation and preparation of Mineral Reserves.

Annual Information Form - 69 - Data Verification The data used in the resource models and resource estimation was reviewed for critical errors and to evaluate the quality of the analytical data. Location data for the collars and downhole survey measurements were checked for gross errors. Measured physical property values were used to recalculate and verify the in-situ bulk density values being used. The assay data was checked for ranking accuracy and the QA/QC results were evaluated statistically and plotted for visual evaluation. The results of the data verification demonstrate the data is adequate for use in Mineral Resource estimation and preparation of Mineral Reserves. Mineral Processing and Metallurgical Testing Significant metallurgical test work has been completed on ore samples from various parts of the Aurizona deposit. Metallurgical test work has historically been completed on laterite, saprolite, transition and fresh rock types from the various deposits. Recent metallurgical test work has been completed on samples of Tatajuba ore and Piaba underground ore relevant to the subject of the Aurizona Technical Report. The Piaba metallurgical test work program was still on-going at the time of the publication of the Aurizona Technical Report. During 2020, a metallurgical test work program was completed by SGS Geosol on samples from Tatajuba ore. The objective of the test work program was to verify the metallurgical response of Tatajuba ore via the existing treatment route at the Aurizona process plant. The scope of the test work program consisted of sample preparation, head assays, comminution tests, gravity pre-concentration followed by leaching of gravity tailings to test treatment of the ore via the existing Aurizona flowsheet. In March of 2021, a metallurgical test work program commenced with SGS Geosol to test samples from the Piaba underground ore. The objective of the test work program was to verify the metallurgical response of the ore from the Piaba ore body at depth via the existing Aurizona treatment route. The scope of the test work program consisted of sample preparation, head assays, mineralogy, comminution tests (SMC and BWi), gravity tests and leaching of gravity tailings by CIL. The test work program was completed over two phases, i.e. variability test work using 18 samples and test work of two composite blends. In general, the ore samples tested from Tatajuba and Piaba underground resulted in a similar metallurgical response of previous ore tested and fall within the expected ranges of historical test work results and are not expected to result in significant flowsheet or operational changes to the existing process plant. Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimate The current Mineral Resource estimate of the Aurizona Property comprises the Piaba, Boa Esperança, Tatajuba, Genipapo and Touro deposits. The resource estimate is an update of the previous Mineral Resource estimates with effective dates of December 31, 2019, for Piaba and Boa Esperança, and effective date of February 28, 2020, for Tatajuba. The Mineral Resource estimates for Genipapo and Touro are presented for the first time.

Annual Information Form - 71 - To sufficiently test the reasonable prospects for eventual economic extraction by an open pit, AGP used MinePlan’s pit optimiser with input parameters to evaluate the portions of the block model that could be extracted economically. The pit optimization parameters are summarised in Tables 2, 3, and 4. The results of the pit optimisation are used to constrain the Mineral Resource with respect to the CIM Definition Standards and does not constitute an attempt to estimate Mineral Reserves. The open pit resources are restricted to blocks contained within the optimised pit, and above a datum that is the lower of 20 m below the reserve pit or 20 m below the fresh rock – transition contact. Block model quantities and grade estimates were classified in accordance with the CIM Definition Standards for Mineral Resources and Mineral Reserves by Trevor Rabb, P.Geo., a Qualified Person. Geologic interpretations were performed by MASA and EEC in Datamine Studio and Micromine software. Interpretations were imported into Leapfrog software to assist with generating final resource domains. Estimation of Mineral Resources was completed using Micromine software. The databases were provided by Equinox Gold and validated for adequacy by Eleanor Black, P.Geo., a Qualified Person. There are no known factors related to metallurgical, environmental, permitting, legal, title, taxation, socio-economic, marketing, or political issues which could materially affect the Mineral Resource estimates.

This Mineral Reserve estimate is as of June 30, 2021 and is based on the Mineral Resource estimates for Piaba, Boa Esperança, Tatajuba, and Genipapo all dated June 30, 2021 by EEC. The Mineral Reserve calculation was completed under the supervision of Gordon Zurowski, P.Eng. of AGP., who is a Qualified Person as defined under NI 43-101. Mineral Reserves are stated within the final design pits based on a $1,350/oz gold price. 2. The gold cut-off grades used were: • Piaba Open Pit – 0.35 g/t (laterite, saprolite, transition), 0.41 g/t (rock) • Tatajuba Open Pit – 0.43 g/t (laterite, saprolite, transition), 0.47 g/t (rock) • Boa Esperança, Genipapo Open Pit – 0.36 g/t (laterite, saprolite) • Piaba Underground – 1.80 g/t (rock) 3. Open pit mining costs varied by area but averaged $2.25/t mined and included an extra $2/t for ore haulage to the process plant from Tatajuba.

Annual Information Form - 73 - 4. Underground Mining costs averaged $32.78/t ore mined. 5. Processing costs averaged $11.52/t ore based on variable costs by material type of $7.84/t for laterite/saprolite, 6. $8.08/t for transition and $12.63/t for fresh rock. 7. G&A was $6.47/t ore processed. 8. LOM gold recovery is 90.5%. Recoveries varied by area and material type. The responsible Qualified Person has not identified any known legal, political, environmental, or other risks that would materially affect the potential development of the Mineral Reserves. Mining Operations Aurizona is an open pit operation using conventional mining equipment. Open pit mining is being completed by a local Brazilian contractor. The Life-of-Mine (LOM) plan includes the addition of underground mining beneath the Piaba pit that assists in extending the mine life to 2032. The mine schedule is based on 2021 Mineral Reserves using the Piaba, Piaba East, Boa Esperança, Tatajuba, and Genipapo pit areas plus the Piaba Underground. It totals 32.3 Mt of Proven and Probable Mineral Reserves ore grading 1.60 g/t gold to the process plant over a current design life of 11 years. The ore tonnage is made up of 16.6 Mt of Proven Mineral Reserves grading 1.39 g/t gold and 15.7 Mt of probable reserves grading 1.82 g/t gold and includes 0.3 Mt of Proven Mineral Reserves ore at 0.92 g/t gold in the stockpile from 2021 mining activity. Waste tonnage totals 96.9 Mt to be placed in the various waste rock management facilities. The overall strip ratio is 3.79:1 mined. Highwall slope angle criteria vary by area and pit. Previous slope study work by third party consultants remains valid and was used in the update of the pit designs. The slope information from Piaba was applied to Tatajuba and Genipapo due to similar lithology and weathering profiles. In general, the inter-ramp angles vary from 33 to 60 degrees depending on pit area and wall orientation. This is due to foliation present parallel to the walls in certain zones. Five open pit areas are considered in the reserves statement: Piaba (4 phases), Piaba East, Boa Esperança, Tatajuba (2 phases), and Genipapo (2 pit areas each with 1 phase). The Boa Esperança open pit will become a freshwater storage facility once excavated. Underground mining beneath the Piaba open pit will be accessed with a portal located in fresh rock at the western end of the Piaba pit. The main ramp will initially be a single decline for the first 735 m where it will connect with the main return ventilation raise and utilidor/emergency egress. From there the ramp will become a twin development with the second decline designated as the return air decline for ventilation. This method avoids the need for costly ventilation raises through laterite, saprolite and transition materials. The initial access will be used for exploration, geotechnical data collection and training purposes while the mining permit is in process, then transitions to the production ramp once mining commences. The final ramp will access the seven underground zones outlined as part of the mine plan and comprising the reserves over its 2 km length from the portal. Additional development for each of the zones will come off the main ramp. The method employed will be longhole mining with a 23 m sub-level vertical interval and will use either a permanent rib pillar or cemented rockfill. The use of cemented rockfill has been allocated to the crown pillar area and stopes with widths exceeding 8 m due to geotechnical considerations. A 28 day curing period has been included in the mine schedule for cemented stopes. The other stopes will use a permanent rib pillar with uncemented rock backfill. The percentage of stopes with rockfill is 83% while the percentage requiring cemented rock fill is 17%.

Annual Information Form - 74 - Underground mining will be completed with owner-operated equipment except for occasional specialized contractor work. The normal underground support equipment is part of the fleet plus the following major underground mining equipment: • 1 - 6 t load haul dump loader (LHD) • 11 - 10 t LHD • 16 - 27 t Highway trucks • 4 - Drill jumbos (2 boom) • 3 - Longhole drills • 1 - Slot raise borer Underground production is expected to begin in the last quarter of 2023. The daily mining rate is expected to increase to 580 t/d by the end of 2024 and be 2,700 t/d at the end of 2025. Underground mine production will maintain a daily rate above 3,100 t/d from 2026 until mid-2029 at which time daily production will decline until the mine is exhausted in mid-2031. The mine schedule anticipates a peak of 3.15 Mt of ore to the processing plant in 2023 then lesser amounts in the following years. This peak is possible due to the higher percentage of laterite, saprolite and transition material which allows a slight increase in plant throughput. Total mine production peaks at 25.8 Mt in 2023 then declines as the mine advances. Underground mine feed is expected to start in 2023 and continues until 2031. Production in 2031 and 2032 includes the crown pillar removal. Processing and Recovery Operations The Aurizona process plant treats the ore via a conventional cyanidation process. Run-of-mine ore is processed using a conventional primary crusher and SAG-Ball mill comminution circuit followed by a gravity circuit, CIL process and associated gold recovery and carbon handling circuits to produce gold doré. CIL tailings are treated via cyanide destruction process prior to deposition into a Tailings Storage Facility (TSF). The process plant was upgraded during the recent construction project in 2018-2019 and recommenced operations in May 2019. The leach/CIP circuit was subsequently converted to a CIL circuit in 2020. The process plant was upgraded to treat 8,000 t/d ore (2.9 Mt/a) based on a blend of laterite/saprolite, transition and fresh rock. The process plant has been generally treating ore feed grades nominally ranging from 1 g/t to 2 g/t, mainly laterite, saprolite and transition ore blends, and achieving approximately 90.5% average recovery. The process plant is not expected to require any major modifications with the mine expansion plans, including the Piaba underground, although the Company is installing a new pebble crusher to help maintain plant productivity as the percentage of fresh rock ore feed increases. The LOM average fresh rock percentage is 76% while the later years will have periods of 100% fresh rock. The average gold recovery is expected to remain at 90.5%. Infrastructure, Permitting and Compliance Activities Infrastructure The existing Aurizona mine site includes the open pit operation and infrastructure such as camp facilities, tailings storage facility, waste disposal areas, power, water, and the processing plant. Underground mine infrastructure includes a utilidor raise to surface, dewatering system, power distribution, communications, underground workshop, fuel and lube supply, hydraulic bulkheads for crown pillar removal, and temporary explosive storage.

Annual Information Form - 75 - The regional utility, Companhia Energética do Maranhão, provides 15 MW power supply via a 69 kV overhead powerline to an outdoor substation located adjacent to the process plant. Process water included with the tailings is stored in the TSF and recycled to the process plant. Fresh water storage will be sourced from the Boa Esperança reservoir, following the mining of this small pit later in 2022. The Boa Esperança reservoir will have a capacity of 900,000 m3 of fresh water. A drainage ditch around the Piaba pit is being expanded along the southern perimeter and extended further north along the northern limit of the pit. This ditch collects surface water to prevent it from entering the active pit area and allows the water to drain away from surface infrastructure to pumping locations. The TSF will be expanded based on having a capacity for 33.2 Mt of processed ore and there is potential for future expansions. After detoxification of cyanide, slurried tailings are pumped from the process plant to the TSF and spigoted from the dam crest. Water is recycled to the process plant. There are six different Waste Rock Storage Facilities required over the LOM to accommodate the 96.9 Mt (53.1 Mm3) of waste material. Two new roads are required to access Tatajuba and Genipapo, respectively. The road to Tatajuba will be 4.1 km long and connect with the existing haul road along the north side of the Piaba pit. The Genipapo access road will be 2.7 km long and connect to the Piaba East access road. The Piaba pit will expand to the west which requires the relocation of the community access road. Permitting and Compliance MASA maintains an Environmental Operating License supported by the ANM mining concession No. 1201/1988, ratification No. 25/2019, totalling 9,982 ha. The process for change or expansion involves one mining concession application with the three-phased (Preliminary License – LP, Installation License – LI, Operation License – LO) environmental process in progress. MASA has obtained permits and authorizations from federal, state, and local agencies to operate current facilities and activities. Equinox Gold is in compliance with all issued permits. MASA carries out regular and frequent monitoring of noise, vibration, effluents discharge, and air quality as part of MASA's Environmental Management Plan, as well as its environmental influence in the community area. Residue management is carried out systematically, with garbage collection, focusing on reduction, reuse, and recycling, and completing this control. There is an industrial incinerator that performs > 98% reduction of non-recyclable and hazardous residues. MASA maintains an Environmental Recovery Program for Degraded Areas with the application of techniques to enrich the vegetation and rehabilitation. Specimens of flora for application in the rehabilitation of areas are gathered and maintained in a nursery. The nursery produces up to 18,000 seedlings a year to be used in reforestation. With the support of MASA’s Security team, forest protection actions are also carried out daily to inhibit hunting and fishing in the areas of legal reserve and permanent preservation. Equinox Gold is a signatory to the International Cyanide Management Code; the mine is seeking to become International Cyanide Code “Certified” through the development and implementation of a Cyanide Management Plan (and training). Control and prevention procedures and actions are in use for the handling, use in the process, treatment, and neutralization of cyanide in the tailings. MASA will be required to update licenses and permits in compliance with regulatory requirements to permit the construction and operation of the proposed Aurizona expansion to Piaba underground and satellite open pits. Equinox Gold has developed working relationships with regulatory agencies and the public. One of the key tools in ensuring effective communication between the company and the communities is the grievance mechanism and the

Annual Information Form - 76 - broad aspects of social investment. The site operations maintain a direct dialogue with the areas of influence, keeping track of all communication and relation through a record data that enhance the principles of Cultural Appropriateness, Accessibility, Transparency and Accountability. The social investment is organized to work with local assets and necessities, engaging the communities to provide internal solutions for their challenges and at the same time providing external resources, through training, revenue generation projects, education, culture, and sports initiatives. The site operations also monitor and define constantly initiatives to adopt as infrastructure investments to improve local conditions and allow the regions to develop alongside the production throughout the years. Economic Analysis A discounted cash flow model was prepared to complete the economic analysis. The economic analysis uses the Mineral Reserves and LOM plan presented in this report and confirms the outcome is positive cash flow that supports the statement of Mineral Reserves. The analysis was completed with a gold price of $1,500/oz and is shown in Table 7. The results indicate a post-tax NPV5% of $314 M for the 11-year mine life. Taxation included in the analysis reflects the current Brazilian legislation. The applicable fiscal benefits are also included in this economic analysis. Royalty payments are included for several royalties, both private and the Brazilian government. The estimated royalty payments for the life of the mine totals $100 M. The analysis indicates the project is most sensitive to gold price followed by exchange rate. This is shown in Table 8. The calculation for Internal Rate of Return (IRR) and payback period are not included as the addition of the other new areas (satellite open pits and underground) are additive to the existing operation and makes IRR and payback somewhat irrelevant values.

Costs are variable depending on whether ore mined and milled is classified as oxide, transitionary or fresh rock. Costs are based on whether the material being processed is stockpiled or in situ material. Capital and cost estimates in the tables above are based on the Aurizona mine plan and Equinox Gold’s current estimates as of December 31, 2023. Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates and changes to current mining operations or the mine plan. The current mine plan is based on existing Mineral Reserves. Ongoing exploration and analyses at operating mines are conducted with a view to identifying new Mineral Resources and upgrading existing Mineral Resources to higher confidence levels and potentially into new Mineral Reserves. If new Mineral Reserves are successfully identified, it may alter the current mine plan and potentially extend the mine life. Recent Exploration, Development and Production Exploration A total of 7,630 m was drilled at Aurizona in 2023, comprising 4,014 m of core drilling and 3,616 m of RC drilling. The primary focus being resource delineation of the western extension of the Tatajuba deposit that was discovered in 2022. The Company completed 3,729 m of core drilling and 1,966 m of RC drilling on regional targets during the year. Planned exploration at Aurizona in 2024 includes approximately 16,500 m of drilling primarily focused on regional exploration targets. Development During 2023, sustaining capital expenditures totaled $41.6 million, primarily relating to capitalized stripping and construction of a new tailings storage facility. Non-sustaining capital expenditures totaled $8.3 million primarily relating to engineering studies for the portal and decline for underground development and drilling. Budgeted sustaining expenditures at Aurizona of $58 million in 2024 include $35 million in capitalized stripping and $16 million for TSF expansion. Budgeted non-sustaining expenditures at Aurizona of $11 million in 2024 primarily relate to underground infrastructure and development.

Aurizona production guidance for 2024 is 110,000 to 120,000 ounces of gold, with cash costs of $1,070 to $1,170 per ounce and AISC of $1,575 to $1,675 per ounce.

Annual Information Form - 79 - Fazenda Mine Fazenda is primarily an underground mining operation located in Bahia State, Brazil. Fazenda has been in operation since 1984 and was acquired by Equinox Gold in March 2020 through the Leagold Transaction. On September 8, 2021, Equinox Gold reported an updated Mineral Reserve and Mineral Resource estimate for Fazenda. Unless otherwise indicated, the information that follows relating to Fazenda is based on, derived substantially from, and in some instances is a direct extract from, the Fazenda Technical Report. Technical information disclosed since the effective date of the Fazenda Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151151. The information below is based on assumptions, qualifications and procedures that are set out only in the Fazenda Technical Report and reference should be made to the full text of the Fazenda Technical Report which Equinox Gold has filed under its SEDAR+ profile at www.sedarplus.ca, its EDGAR profile at www.sec.gov/EDGAR and which is also available on Equinox Gold’s website at www.equinoxgold.com. Project Description, Location and Access Fazenda is located in the eastern part of Bahia State, Brazil, 180 km northwest of the state capital city of Salvador. Topographic coordinates of the Mine area are 11° 27' south latitude and 39° 03' west longitude. Fazenda can be accessed from Salvador by way of approximately 180 km of paved road to Teofilândia, and locally by a 12 km unpaved road. Equinox Gold owns 100% of the mineral licenses through its indirect wholly owned subsidiary Fazenda Brasileiro Desenvolvimento Mineral Ltda. Fazenda covers an area totaling 58,651 ha, including 28 exploration licenses (33,522 ha), 15 exploration applications (12,909), 8 mining permits (7,732 ha), 3 mining permits in application (2,556 ha), and 1 exploration licence with a Final Positive Exploration Report submitted (1,932 ha). In Brazil, the EL holder pays an annual fee per hectare to ANM based on the number of hectares held (as of March 2021, the fee ranges from R$3.70/ha to R$5.56/ha); and reports of exploration work performed must be submitted when required according to law. ELs are valid for a maximum of three years, with a maximum extension equal to the initial period, issued at the discretion of the ANM after the submission and approval of a partial exploration work report. After submitting a Final Exploration Report, the EL holder may request a mining concession. Mining concessions are granted by the Brazilian Ministry of Mines and Energy, are renewable annually, have no set expiry date, and remain in good standing subject to submission of annual production reports and payments of royalties to the federal government. The ELs, Exploration Applications, mining concessions and mine applications, including applicable expiry dates held by Equinox Gold are listed in the Fazenda Technical Report. The Brazilian government collects a 1.5% gross revenue royalty on all gold operations in Brazil. This royalty is split among the various levels of government. Under Brazilian law, surface owners have a right to a 0.5% gross revenue royalty. Fazenda owns most of the surface rights over planned production areas; however, there are a few small parcels of land to which this royalty applies. Equinox Gold: (i) is not aware of any environmental liabilities on the property; (ii) has all required permits to conduct work on the property; and (iii) is not aware of any other significant factors or risks that may affect access, title, or the right or ability to perform work program on the property.

Annual Information Form - 80 - History Table 1 summarizes Fazenda’s exploration history post-1976 and prior to Equinox Gold’s acquisition: Table 1: Exploration History Year Description Post–1976 Companhia Vale do Rio Doce (CVRD) discovered the Fazenda Brasileiro deposit in the late 1970s and began mining operations in 1984 with an open pit and heap leach gold operation. In 1988, underground mining operations commenced. Fazenda mine has been in continuous production since start-up. 2003 Yamana Gold Inc. (Yamana) acquired Fazenda and carried out drilling of approximately 20,300 holes for approximately 905,000 m. 2015 Brio Gold Inc. (Brio) acquired Fazenda and carried out drilling of approximately 4,100 holes for approximately 220,000 m. 2018 Leagold Mining Corp. (Leagold) acquired Fazenda through its acquisition of Brio. 2020 Equinox Gold acquired Leagold and assumed ownership of Fazenda. The Fazenda Technical Report summarizes historical production for the heap leach, CIP, and subsequent CIL operations. Fazenda had produced approximately 3.4 Moz of gold as of December 31, 2020. Geological Setting and Mineralization Fazenda is situated within the Rio Itapicurú Greenstone Belt (RIGB) which is a 100 km-long and 60 km-wide north– south trending volcano-sedimentary belt situated within the São Francisco Craton. The Weber Belt is a 10 km long, arcuate east–west-trending, south-dipping shear zone. It is abruptly folded toward the south, near its western extremity, reflecting the deformation generated by a later sinistral north–south structure. The Weber Belt hosts the most significant gold mineralization in the RIGB, and Fazenda lies within it. Fazenda is an epigenetic, structurally controlled, and hydrothermally altered Precambrian quartz vein- hosted lode- gold deposit that has been subjected to greenschist facies metamorphism. There is suggestion of a partial syngenetic origin for the gold because of the anomalous, 0.05 to 0.10 g/t Au content present throughout visibly unmineralized quartz-chlorite schist. The main mineralization is hosted by quartz-albite-sulphide veins within the upper horizon of chlorite schist known as CLX1. Mineralization is also found stratigraphically below the CLX1 mineralized domain, in the CLX2 and Canto (AGV) horizons. The stacked veins vary in true width from 1.5 to 40 m and horizontal mining widths vary from 3 to 40 m. The regional strike of mineralization is north–south, while locally the veins are generally arcuate in an east– west trend, and south dipping at 40° to 70°, with a shallow-to-moderate east plunge. The plunge is quite variable, with some zones plunging westerly. Exploration Most of the recent exploration at Fazenda has been drilling to increase and/or replace Mineral Reserves depleted during mining. Much of this exploration drilling has been carried out from underground drifts with the objective of identifying new resources and converting Mineral Resources to Mineral Reserves. CThe exploration team is developing new geological models to guide future exploration. Exploration potential exists along strike and at depth. The exploration team is also carrying out regional reconnaissance over several targets, including geological– structural mapping, soil geochemistry sampling, and early-stage exploratory drilling.

Annual Information Form - 81 - Since mid-2020, an integration and interpretation of combined underground and superficial geological datasets is being completed to identify untested potential targets hosted within rocks of the Weber Belt and active exploration permits across the RIGB, with a complete revision of the existing and new geophysical and remote sensing for target generation and ranking. The main components of the 2020 review and interpretation, which provided data for input to the 2021 exploration program were: • Data compilation and integration • Geophysical interpretation • Target generation • Geological/structural mapping over selected targets • Soil and rock sampling. Drilling Prior to 2003, CVRD conducted surface diamond drilling in the initial search for new mineralization. This was followed by underground fan drilling on a 100 by 50 m grid using B-sized core drilling equipment to establish Indicated Mineral Resources. A-sized core drilling on a 25 by 10 m grid pattern was then used to upgrade the classification of Mineral Resources from Indicated to Measured. After 2003, both Yamana and Brio maintained the same methodology of drilling as CVRD. In 2020, Equinox Gold completed drilling programs totaling 53,201 m to upgrade Inferred Mineral Resources to Indicated, and converting Indicated to Measured, to support the Fazenda operation. In 2021, Equinox Gold advanced a more than 55 km underground drilling program aimed at upgrading Inferred Mineral Resources to Indicated and convert Indicated to Measured to support the Fazenda operation. Drilling results to the date of the Fazenda Technical Report confirmed opportunities to increase both Mineral Reserve and Mineral Resource estimates. Sampling, Analysis and Data Verification Sample Preparation, Analyses and Security Sample preparation and assaying procedures are as follows: • Each sample is dried at 100°C (±10°C). • All core samples are coarse-crushed to P90 2.0 mm. • This material is passed through a rotary splitter. A 500 g aliquot is taken and pulverized to P95 150 mesh. The crushing and grinding equipment are cleaned with compressed air after each sample, and barren silica sand is passed through the equipment prior to running batches of samples. Gold determinations are carried out on 50 g (±0.10 g) samples using FA/AAS. Granulometric tests are performed three times per shift on the crushing and pulverizing processes. Preparation duplicates are inserted every 20 to 30 samples. The mine site is surrounded by a security fence, and there is controlled access at a gatehouse, staffed full time by security personnel. At the drill site, samples are under the control of Fazenda employees and employees of the drilling company. Drilling company personnel deliver samples daily to Fazenda personnel at the mine site sample processing facility. Only employees of Fazenda and of the drilling contractor are authorized to be at the drill sites and in the sample processing facility. Core is normally collected from the drill rig and taken directly to the core yard

Annual Information Form - 82 - for sampling. Samples are then sent directly to the laboratory at the mine site, following industry standard sample security procedures. All analytical pulps and archival split core are stored within the secure mine compound. Samples are collected by a trained sampler under the supervision of a technician or a geologist, with all QA/QC samples inserted within a sequentially numbered sequence and recorded. Equinox Gold maintains the Fazenda laboratory. The QA/QC program used at Fazenda includes inserting Certified Reference Material, blanks, and duplicates into the sample stream. For each lot of samples analyzed, the results are reviewed and all failed samples are rerun by the laboratories, which complies with the best standards of the mining industry, and underpins the accuracy of the Mineral Resource estimate. The Fazenda laboratory meets the requirements of ISO 17025:2005 and ISO 17025:2017. Data Verification Equinox Gold reviewed the methods and practices used to generate the resource database (including drilling, sampling, analysis, and data entry). The verification included a review of the QA/QC methods and results, standard database validation tests, and several site visits. Equinox Gold selected a number of drill holes to verify the described methods and practices by performing the following digital queries: • Reviewing the drill hole traces in three-dimensional (3-D), level plan, and vertical sections. • Querying the database for missing or repeated data, unique headers, duplicate holes, and gaps or overlapping intervals. • Ensuring that the total depth recorded in each drill hole database table was consistent. • Visiting the core handling facility. • Reviewing core logs for several drill holes during the site visit. The global database was divided into seven separate databases, one for each deposit. Data verification was performed for each deposit database separately. No issues were found in the validation process, and the database was considered appropriate for the geology and style of mineralization. The practices and procedures adopted in the Fazenda database, and the data contained therein are acceptable to support Mineral Resource and Mineral Reserve estimation. Mineral Processing and Metallurgical Testing Fazenda currently operates at P80 80 μm recovering 90.6% on average, after a series of process improvements implemented along 2020 and 2021. The process had been improving every year to get more extraction efficiency as the feed grade decreases each year. To reduce gold recovery losses with more carbonaceous ore in the blend, test work was carried out using kerosene, resulting in a gold recovery increase of approximately 2%. The pH adjustment used to be 9.8, which was controlled by dosing lime at 1,100 g/t in the cyanide dosing tank. Then the pre- aeration tank was transformed into a pre-lime tank at a dosage of pH 10.2. The outcome of this process-change was an increase in lead nitrate effectiveness that resulted in an approximately 10% reduction in cyanide consumption and an approximately 2% increase in gold recovery. Fazenda will investigate the increase of the dissolved oxygen in the pre-aeration tanks to improve the gold dissolution and thereby increase gold recovery. The test work will entail dosing hydrogen peroxide in the pre- aeration tanks at 200 g/t in 2021.

Annual Information Form - 83 - The current first step of the elution process is desorption. The second step is acid washing, which removes base metals and scaling compounds such as calcium carbonate and sodium silicate from the carbon after the elution. The current elution recovery is approximately 90%; however, test work is needed to change the order of the steps to see if recovery is increased, and at the same time avoid damage to the regeneration kiln. Currently the regeneration kiln is deteriorated and is not able to regenerate the total carbon in the circuit. A study of the process was carried out and indicated that on average regenerated carbon activity is 25%, affecting gold adsorption. A new regeneration kiln with a capacity of 500 kg/h will be installed. Beyond process improvements listed above, several structural refurbishments in the metallurgical plant are necessary, such as refurbishing: • Pillars that support the leaching tanks • Tanks and channels of the leaching area • Support beams of the desorption building • Columns and beams in the milling building • Leaching platform structures. The old CVRD heap leaching waste dumps show a potential for processing in the future, with an estimated 3 Mt of oxidized material at an estimated average grade of 0.6 g/t Au. Test work was carried out, with gold recovery higher than 70%. Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimate Fazenda constructed a block model to estimate the Mineral Resources as of December 31, 2020, using the results of new grade-control drilling that Fazenda conducted during 2019 and 2020. Equinox Gold audited the model and found that it was reasonably prepared and provided a good representation of the geologic data. The resource model has been prepared using appropriate methodology and assumptions. These parameters include: • Treatment of high assays • Compositing length • Search parameters • Bulk density • Grade estimate validation • Cut-off grade • Classification. Table 2 summarizes the updated Mineral Resource estimate exclusive of Mineral Reserves, as of December 31, 2020. This Mineral Resource estimate conforms to CIM Definition Standards (2014). The responsible Qualified Person is not aware of any environmental, permitting, legal, title, taxation, socioeconomic, marketing, political, or other relevant issues that would materially affect the Mineral Resource estimate.

The Mineral Resources statement was been prepared by Felipe Machado de Araújo, MAusIMM(CP), who was a full-time Equinox employee and is a QP as defined by NI 43-101. 8. Totals may not add due to rounding. Mineral Reserve Estimate Fazenda prepared the Mineral Reserve estimate as of December 31, 2020. The Mineral Reserve estimates have been prepared using appropriate methodology and assumptions. The responsible Qualified Person is of the opinion that the Measured and Indicated Mineral Resources can be classified as Proven and Probable Mineral Reserves, and is not aware of any mining, metallurgical, infrastructure, permitting, or other relevant factors that could materially affect the Mineral Reserve estimate.

The Mineral Reserve statement has been prepared by Hugo Ribeiro Andrade Filho, FAusIMM (CP), a full-time Equinox employee, who is QP as defined by NI 43-101. 7. Numbers may not add due to rounding. Mining Operations Underground Underground mining employs blasthole stoping from sublevels developed in the mineralization’s footwall. The stoping areas are accessed initially from 5 m wide by 5.5 m high main haulage ramps developed at 15% road grade in the footwall, which lead to primary development crosscuts, secondary development drifts, crosscuts 4.5 m wide by 4.9 m high, and secondary development drifts and crosscuts also 4.5 m wide by 4.9 m high. Sublevels are spaced at 20 m vertical intervals. Mined out stopes are not backfilled. At Fazenda, active stoping areas are called bodies, with the following names: B, C, D, E, EW, EDEEP, and F. All bodies have a planned dilution of 15%, except for the EDEEP and EW, which have dilutions of 20%. Planned mining recovery is estimated to be 90%. From the sublevels, access drifts are developed into the stoping areas, and blastholes fan-drilled into the mineralization are used to further define the boundaries of the mineralization and design the ultimate blast patterns. After blasting, remote-controlled, 10-tonne-capacity load-haul-dump machines are used to load and haul the ore from the stoping areas to 30-tonne-capacity haulage trucks at loading points in the sublevels. The plunge of the orebody is approximately 45° dip and the maximum stope heights are 20 m. Future operations in the deeper areas of E Ramp will have higher haulage costs that will be partially offset by the shorter underground haulage in the F and G Ramps. To date, most of the waste rock has been hauled to surface.

Annual Information Form - 86 - Open Pit Currently, several small open pits are in operation, and mining is being completed using contractors. These small pits are 25 to 80 m deep and are being developed using air-track drills and backhoe excavators for mining, and highway-type trucks for haulage to the mill. Pit depths are dependent on the economics of stripping overlying waste. Mineralization exceeding pit depths is considered for underground mining. Processing and Recovery Operations The process plant is a CIL operation, which can process up to 3,300 t/d (1.35 Mt/a). The overall process flowsheet consists of: • Three-stage crushing circuit • Two ball grinding mills, closed circuit with hydrocyclones • Thickener to produce a leach feed of 50% solids • Cyanide leaching circuit • Zadra pressure stripping of the carbon • Electrowinning of the carbon eluent • Casting of gold doré bars in an induction furnace. Infrastructure, Permitting and Compliance Activities Infrastructure All the necessary infrastructure for the operation is in place, which includes, but is not limited to a 470 m vertical shaft; a series of underground ramps; the CIL milling and processing facility; lined heap leach pads and associated process equipment; geomembrane-lined tailings storage facilities; warehouse, maintenance shops, drill core logging, splitting, and storage facilities; assay laboratory; cafeteria; a helipad for emergency use and shipment of gold doré bars; office complexes; a water supply system; a fuel station; and explosives magazine. Fazenda has all the necessary roads, power lines, access, and medical facilities for workers and services to the mine. Water is supplied by a series of well fields with a total production capacity of 310 m3/h. The power requirement for the mine and site facilities is approximately 9.95 MW, which is supplied by the local grid. One of the main constraints on Fazenda’s production is frequent outages of the COELBA power grid; this made it necessary to install diesel generator sets as synchronized backup power to operate critical and emergency equipment during a grid power outage. Permitting and Compliance Fazenda has a comprehensive environmental policy. This policy has been developed in line with the Mine Closure Plan (MCP), as outlined by ANM. In 2021, Mineral Engenharia e Meio Ambiente, an external consulting firm prepared the MCP for Fazenda. The environmental authorities in Brazil use the MCP as a commitment to complete the rehabilitation required for mine closure. The guidelines primarily involve revegetating the areas with native species, covering the pits, or converting the pits to store water, along with stabilizing and rehabilitating waste dumps and tailings dams. Demolishing and removing all structures and facilities that will not be used in the future is also included. All required environmental licences and permits to conduct work on the property are in good standing or currently being obtained.

Annual Information Form - 87 - Fazenda has developed a program for social and community involvement in the area of the Fazenda operations, which should be maintained for the life of the mine. The main socioeconomic impacts that will be generated by the Fazenda closure include unemployment, decreased tax revenues, end of demand for local regional suppliers, reduction in personal income, and the end of projects with the local communities. Fazenda has developed mitigation measures for some of these impacts. Current Capital and Operating Costs The following information provides a summary of activities and expenditures completed in 2023 and the Company's forecasts for 2024 for Fazenda.

Totals may not add due to rounding. 2. Operating costs include all mining, processing and general and administration costs including waste stripping. 3. Costs are variable depending on whether ore mined and milled is classified as oxide, transitionary or fresh rock. Costs are based on whether the material being processed is stockpiled or in situ material. Cost estimates in the tables above are based on the Fazenda mine plan and Equinox Gold’s current estimates as of December 31, 2023. Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates and changes to current mining operations or the mine plan. The current mine plan is based on existing Mineral Reserves. Ongoing exploration and analyses at operating mines are conducted with a view to identifying new Mineral Resources and upgrading existing Mineral Resources to higher confidence levels and potentially into new Mineral Reserves. If new Mineral Reserves are successfully identified it may alter the current mine plan and potentially extend the mine life.

Annual Information Form - 88 - Recent Exploration, Development and Production Exploration During 2023, the Company drilled 53,947 m of core focused on Mineral Reserve replacement in the immediate underground mine area. An additional 11,270 m of RC drilling was completed by the end of Q2 2023, including 7,080 m on the Canto 2, Canto West and PPQ Gap brownfield targets and 4,190 m on the greenfield Barrocas SW target, which completed the planned surface exploration program for 2023. Planned exploration at Fazenda in 2024 includes 60,000 m of core drilling in the immediate underground mine area and 6,700 m of surface drilling on brownfields and regional targets. Development During 2023, sustaining capital totaled $12.2 million, primarily relating to underground development and capitalized stripping. Non-sustaining capital expenditures totaled $10.9 million, primarily relating to exploration drilling. Budged sustaining expenditures at Fazenda of $25 million in 2024 primarily relate to $6 million for underground development, $7 million for equipment acquisition, and $5 million for exploration. Production Fazenda produced a total of 66,375 ounces of gold during 2023 at cash costs of $1,230 per ounce and AISC of $1,448 per ounce. Fazenda’s production guidance for 2024 is 65,000 to 70,000 ounces of gold, with cash costs of $1,195 to $1,295 per ounce and AISC of $1,560 to $1,660 per ounce.

Annual Information Form - 89 - Santa Luz Mine Santa Luz is the restart of a past-producing open-pit mine located in Bahia State, Brazil. Santa Luz was acquired by Equinox Gold in March 2020 through the Leagold Transaction. Production at Santa Luz commenced in mid-2013 by a previous owner and was suspended in September 2014 due to processing difficulties and lower than planned recoveries. Leagold completed a feasibility study for Santa Luz in October 2018 incorporating resin-in-leach (RIL) gold recovery. Equinox Gold updated Leagold’s feasibility study and on November 9, 2020, commenced full construction of Santa Luz with the objective of restarting production. Santa Luz achieved commercial production effective October 1, 2022. Unless otherwise indicated, the information that follows relating to Santa Luz is based on, derived substantially from, and in some instances is a direct extract from, the Santa Luz Technical Report. Technical information disclosed since the effective date of the Santa Luz Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151151. The information below is based on assumptions, qualifications and procedures that are set out only in the Santa Luz Technical Report and reference should be made to the full text of it which Equinox Gold has filed under its SEDAR+ profile at www.sedarplus.ca, on EDGAR at www.sec.gov/EDGAR and which is available on Equinox Gold’s website at www.equinoxgold.com. Project Description, Location and Access Santa Luz is located within the Maria Preta mining district, 35 kilometers north of the town of Santa Luz, in Bahia State, Brazil. Santa Luz is approximately 240 km northwest of the state capital, Salvador, 115 km by road from Equinox Gold’s Fazenda mine, and 163 km from Yamana Gold’s Jacobina gold mine. Access from Salvador is by way of highway BR-324 to Feira de Santana, BR-116 to Serrinha, BA-409 to Conceição do Coité, and finally BA-120 to Santa Luz. From Santa Luz, the property is accessed by way of a municipal dirt road. The center of the property has approximate latitude and longitude coordinates of 11°00'28" S and 39°18'28" W, respectively. A railway operated by VLI Transportadora links Salvador and the sister cities Juazeiro and Petrolina, and has a station in Santa Luz. A few gravel runways in the region can handle small aircraft, the closest being at the cities of Valente and Serrinha, approximately 20 km and 90 km from Santa Luz, respectively. Since early 2015 the Feira de Santana airport, which is 153 km from Santa Luz, has been operating daily flights from Campinas City, São Paulo state. Santa Luz is a conventional off-road truck and shovel open-pit mining operation, utilizing a mining contractor for material movement. After the pre-production period, the nominal ore production rate over the following eight years is projected to be 2.7 million tonnes per annum (Mtpa), or 7,400 tpd excluding rehandling, plus 1.5 additional years at a lower rate from residual stockpile feed, over the total 9.5 year LOM. The stripping ratio is 4.3:1 waste to ore including stockpiles (or 4.7:1 excluding stockpiles) and 6.9 Mt of pre-stripping is proposed (excluding the rehandling of old stockpiles), based on the mine schedule.

Annual Information Form - 90 - Surface Rights The Santa Luz properties cover an area totaling 48,599.25 ha, including 36 exploration permits (42,666.41 ha), six mining concessions (2,611.69 ha), and four mining concessions in application (3,321.15 ha). Of the 36 exploration permits, eight are at the exploration stage with a Partial Exploration Report submitted to ANM requesting a deadline extension (9,849.47 ha); two are at final exploration stage with the Positive Final Exploration Report already submitted to ANM (1,885.88 ha), indicating reasonable prospects to continue with economical analyses and subsequent mining concession application after ANM’s approval of reports; five are at the final exploration stage with the Negative Final Exploration Report already submitted to ANM (6,711.28 ha), which means that these areas should be considered available after ANM’s approval of reports; and the remaining twenty-one permits are at an exploration stage (24,219.78 ha). One of the exploration permits expired during 2020 and is either in the process of submission of reports or will lapse. This exploration permit does not impact the Mineral Resources or Mineral Reserves, or future operations. The Santa Luz claims cover several farms. Agreements were signed between Yamana and the landowners to allow mining and exploration activities, and these agreements have been transferred to Equinox Gold. Equinox Gold has verified that there are no environmental liabilities on the property. Equinox Gold has all required permits to conduct work on the properties. These permits and their status are listed and described in Section 20 of the Santa Luz Technical Report. Equinox Gold has verified that there are no other significant factors and risks that may affect access, title, or the right or ability to perform the proposed work program on the property. Royalties Royalty agreements currently exist with the Federal Government for 1.5% of gross revenue and with Companhia Sisal do Brasil (COSIBRA) for 1% of gross revenue, and were included in the cash flow and pit optimization analysis. An additional 2% royalty was included for the Companhia Baiana de Pesquisa Mineral (CBPM) area of the C1 deposit. Subsequent to the date of the Santa Luz Report, the COSIBRA royalty was increased to 1.375% of gross revenue. History During the 1970s, Companhia Vale do Rio Doce (CVRD) invested in a regional prospecting program in Bahia state, while other private and state companies carried out intensive prospecting, geological mapping, and research programs. During this time, the Rio Itapicurú Greenstone Belt (RIGB) was identified. Between 1979 and 1981, CBPM conducted several geological and prospecting programs within the RIGB. These activities identified several gold-bearing trends and prospects including deposits within the Santa Luz area, which were mined between 1987 and 1995 by CBPM’s subsidiary Rio Salitre Mineração Ltda. In January 2005, Yamana completed an agreement with CBPM to acquire 7,000 ha of land over the C1 historic mine. Under this agreement, CBPM retains a 2% royalty interest in these concessions. In May 2007, Yamana expanded its land ownership through the acquisition of mining concessions from Mineração Santa Elina (MSE), formerly owned by CVRD, which included the Antas 1, Antas 2, and Antas 3 deposits and associated historic mine workings. The 2007 agreement also retained a royalty interest which was transferred from MSE to Callix Finance Inc. in April 2014 and was finally extinguished through an agreement between Yamana and Callix Finance Inc. in March 2015. In December 2014, it was announced that a new subsidiary, Brio Gold Inc., (Brio) was formed by Yamana to hold Fazenda, Pilar through Companhia Goiana de Ouro, and Santa Luz, as well as some related exploration concessions, all of which were held as non-core assets within Yamana. Brio became an independent, publicly traded company in December 2016. Leagold acquired Brio on May 24, 2018 and became the owner of Santa Luz. On March 10, 2020 Equinox Gold acquired Leagold and became the owner of Santa Luz.

Annual Information Form - 91 - Geological Setting, Mineralization and Deposit Types The Santa Luz project area is hosted within the RIGB, which comprises the northeastern portion of the São Francisco Craton which was formed through the collision of several small Archean cratons during the Paleoproterozoic Trans- Amazon Orogeny (approximately 2 Ga). The Paleoproterozoic aged RIGB is the largest greenstone belt in the São Francisco Craton. Thought to be formed in a back-arc tectonic setting, the north-south trending RIGB extends for approximately 100 km and ranges in width from 30 km to 50 km. It is comprised of three domains (mafic volcanic, felsic volcanic, and sedimentary), all intruded by later granitioid bodies. Gold deposits and prospects in the Santa Luz project area occur in shear and breccia zones at, or proximal to, the faulted contact of the volcanic and sedimentary domains in a continuous, north and locally northeasterly-striking, mineralized zone. Mineralization is associated with quartz-carbonate-sulphide veining and breccia fillings. Significant gold targets and deposits at Santa Luz include C1 (historically called Maria Preta and including Antas 1), Antas 2, Antas 3, Mansinha South, Mansinha North, and Mari. The deposits are considered to be greenstone-hosted gold type deposits, a subgroup of the Orogenic Gold Deposit type. Host rocks include a variety of epizonal dioritic and dacitic intrusive rocks, sedimentary rocks, and felsic to intermediate volcanic rocks. Volcanic and epizonal intrusive rocks are generally porphyritic with fine to medium grained quartz and feldspar phenocrysts. Sedimentary rocks, including tuffaceous rocks, contain variable quantities of organic carbon which appears to be a primary depositional component. More massive volcanic and epizonal intrusive rocks are relatively free of organic carbon. The organic carbon content is a major focus of geologic studies as the carbon interferes with cyanide leach gold recovery. Organic carbon-rich rocks require special treatment to facilitate gold recovery. All rocks of the RIGB have undergone greenschist to amphibolite grade metamorphism. Exploration From 1979 to 1995, CVRD and CBPM undertook several extensive stream sediment and soil geochemistry programs over the entire Maria Preta Gold District in the RIGB. Encouraging results were followed up using geophysics and drilling. Numerous deposits were discovered and mined, commonly focusing on the shallow, oxidized portions of these deposits. Possessing a wealth of historic exploration data, Yamana conducted extensive drilling to develop the C1 and A3 deposits as well as several other prospects in the district. From September 2015 through April 2017, work at Santa Luz by Brio was conducted in two phases of resource, metallurgical, and geotechnical drilling in support of the Santa Luz Technical Report. The majority of the concessions at Santa Luz are at an early exploration stage with limited exploration activity other than regional mapping, regional geochemistry surveys, and airborne surveys, which were completed by previous owners. Drilling Drilling at Santa Luz has been conducted in phases by several companies since 1975. Very limited information on the historical drilling details is available. From 2003 to 2013, Yamana explored the district with 201,379 m of drilling, including 126,658 m of diamond core drilling, spread across numerous deposit areas. Yamana also conducted soil and rock chip sampling and geologic mapping. In 2015 and 2016, Brio conducted 20,590 m of exploration, geotechnical and metallurgical drilling, including 13,425 m of diamond core drilling for resource definition. In late 2016 and early 2017, Brio conducted 4,036 m of exploration and geotechnical drilling.

Annual Information Form - 92 - Leagold did not carry out any drilling at Santa Luz during its period of ownership. Equinox Gold conducted 26,031 m of drilling of nine regional targets in 2021, with the objective of identifying new Mineral Resources and potential targets within the Company’s land package. In total, past owners have drilled a total of 3,884 drill holes collecting over 241,172 m of drill core and chip samples in the district. A drilling summary is included in the Santa Luz Technical Report together with maps of drill hole collars. Sampling, Analysis and Data Verification Sampling of the 2016 and 2017 drill holes focussed on the mineralized zones and a significant length of core above and below the targeted mineralization was sampled to ensure that the mineralized zone was properly modelled. Samples have a nominal length of one metre; however, the length was adjusted so that sample endpoints respected geological contacts. Samples were tagged with a plasticized paper tag indicating the sample number, a duplicate of which was stapled inside the core box. QA/QC samples, including duplicates, blanks, and standards, were incorporated into the sample stream. Santa Luz personnel used independent and internationally recognized laboratories for sample preparation and analysis. The density test samples were sent to the independent ALS Chemex Laboratory in Lima, Peru (ALS Lima), which is ISO 9001:2000 and ISO 17025:2005 accredited. The analytical procedure used was the ALS Chemex OA- GRA09as, in which the core samples are coated in paraffin wax, weighed in air, and then weighed while submerged in water. Core and chips are stored within two purpose-built core sheds on-site, both of which are locked at night. Sample preparation was completed at ALS Chemex in Vespasiano, Minas Gerais, Brazil. This is a laboratory independent of Equinox Gold and ISO 9001:2000 and ISO 17025:2005 accredited. After the samples were crushed and pulverized, pulp splits were sent for geochemical analysis at ALS Lima. Remaining sample material was returned to Santa Luz for storage. A QA/QC protocol for drill hole samples using standard geologic practices in accordance with industry guidelines was used at Santa Luz. The results verified the accuracy and precision of the geochemical analyses, and Santa Luz project personnel believe that the drill results are acceptable to be used for Mineral Resource and Mineral Reserve estimation. The results of the field duplicate analysis are consistent with the natural variability often seen in orogenic gold deposits. In the opinion of the Qualified Person (RPA), sample preparation, analysis, and the security and confidentiality protocols, as designed and implemented, are adequate and generally completed to industry standards and are suitable for use in a Mineral Resource estimate. Verification Audit of Drill Hole Database: RPA conducted a series of verification tests on the drill hole database provided for Santa Luz. These tests included a search for missing information and tables, unique location of drill hole collars, and overlapping sample or lithology intervals. Empty tables were limited to lithology, alteration, and geotechnical results. No database issues were identified. Assay Certificates: RPA compared 2% of assays within the complete Santa Luz drill hole database to assay certificates, including 24% of the C1 assay database. Certificates were provided by Santa Luz personnel and were not sourced from the original assay laboratory. No major discrepancies or limitations were found. Drill Core Review: The core from a number of drill holes was reviewed during the site visit to confirm logging and sampling practices. Acceptable practices were noted.

Annual Information Form - 93 - RPA is of the opinion that Santa Luz data comply with industry standards with no major discrepancies or limitations being found and are adequate for the purposes of Mineral Resource estimation. Mineral Processing and Metallurgical Testing The metallurgical testing programs for the Santa Luz processing facilities began in 2005 and supported a feasibility study conducted by Yamana in 2009. A pilot plant test program was performed in 2009, followed by further pilot plant testing in 2010. Production at the Santa Luz mine and mill commenced in 2013, however, it was discontinued in September 2014 and the facilities were put on care and maintenance, following a period of very low gold recoveries associated with the processing of carbonaceous ores. In late 2014, a metallurgical testing program was initiated by Brio to evaluate the existing process facilities, to determine the causes of the low gold recoveries and to develop a revised flowsheet to successfully process the carbonaceous material at Santa Luz. The naturally occurring carbon was shown in the test work to be strongly preg-robbing. Kerosene was selected as a blinding agent to deactivate the natural carbon prior to CIL cyanide leaching. Gold recoveries were very low in leach tests performed without kerosene. More test work was carried out in 2016 and 2017. This was designed to further develop the proposed whole ore leach flowsheet and formed the basis for preparing the design criteria, process flow diagrams, mass balance, and equipment sizing. The test work was conducted by various laboratories including Commonwealth Scientific and Industrial Research Organisation in Perth, Australia, Hazen Research Inc. in the USA, RDI Minerals in the USA, SGS Geosol Laboratórios Ltda. in Brazil, and the Santa Luz on-site laboratory. The test work program commenced in January 2016. The program included Bond Ball Mill Work index tests for bulk composites of dacite and carbonaceous ore, whole ore cyanidation using both CIL and RIL flowsheet variations, reagent optimization, and variability test work. Further test work was conducted in 2019 at Mintek in South Africa and at the Santa Luz on-site pilot plant to optimize the whole ore RIL processing circuit, to increase the gold grade (and reduce the copper grade) of the loaded resin and to optimize gold recovery from the resin. The results of the programs show that the most favourable option is to process the dacitic and carbonaceous breccia ores together and to use RIL and a kerosene blanking circuit. Blending the dacitic breccia with the carbonaceous breccia results in slightly lower recoveries, due to preg-robbing by natural carbon in the carbonaceous ore. Gold recoveries based on combined feed and test work is approximately 84%. Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimate Mineral Resources for each of the deposits at Santa Luz were estimated by Santa Luz personnel in 2017 with the support of resource, geotechnical and metallurgical drilling and extensive metallurgical testwork conducted in 2015, 2016, and 2017. The Mineral Resources were reviewed by RPA (now SLR Consulting Ltd.).

Annual Information Form - 94 - Notes: 1. CIM Definition Standards (2014) were followed for Mineral Resources. 2. Underground Mineral Resources are reported at a cut-off grade of 1.5 g/t Au. 3. Open Pit Mineral Resources are reported at a cut-off grade of 0.50 g/t Au. 4. Mineral Resources are inclusive of Mineral Reserves. 5. Mineral Resources are estimated using a gold price of $1,500/oz and constrained by a Whittle pit shell. 6. Totals may not add due to rounding. Lithology, alteration, and mineralization domains were constructed over each deposit using gold grade thresholds specific to each area, in combination with lithology, alteration, and structural information. Variography and basic statistics were used to inform interpolation plans, which used Ordinary Kriging or Inverse Distance Squared methods to estimate gold values from capped gold composites within discrete block models in a series of interpolation passes. Density was averaged from on-site samples and applied to lithology and weathering domains in each deposit. Blocks were classified based on interpolation pass and Kriging variance. RPA conducted a series of block validation and data integrity tests on the block model. Mineral Resources were constrained using a Lerchs Grossmann pit. The Mineral Resource is current and no additional work was undertaken after the estimate was completed. Mineral Reserve Estimate During May 2020, a number of checks to verify the procedures and numerical calculations used in the estimation of the Mineral Reserves were carried out and the Qualified Person visited Santa Luz in June 2020. The open pit Mineral Reserves as estimated are summarized in the Table 2, using a gold price of $1,350/oz with a pit design based on selected pits shells and an overall metal recovery of 84% for all types of ore. Mineral Reserves are estimated only for C1, Antas 3, and stockpiles; Antas 2 has not been delineated enough to classify it as a Mineral Reserve. The Qualified Person is of the opinion that the Measured and Indicated Mineral Resources within the final pit designs for Santa Luz can be classified as Proven and Probable Mineral Reserves. The mine plan is based on Proven and Probable Mineral Reserves of 24.9 Mt grading 1.34 g/t gold for 1,074,941 ounces of gold contained in the C1 and Antas 3 deposits and in existing stockpiles. Initial production will mine ore from the C1 deposit and stockpiles; Antas 3 will be mined from 2024 to 2029.

Mineral Reserves are quoted at cut-off grades of 0.52 g/t Au for dacite-leachable and carbonaceous ore, for the C1 deposit; and for the Antas 3 deposit, cut-off grades of 0.54 g/t Au for dacite-leachable and carbonaceous ore and 0.45 g/t Au for dacite- high-sulphide. 4. C1 and Antas 3 use a 10 m bench height (flitch height 5 m benches). 5. Process recovery of 84% for all types of ore. 6. Mineral Reserves were run using a long-term gold price of US$1,350/oz. 7. Totals may not add due to rounding.

Annual Information Form - 95 - Mining Operations The feasibility study summarized in the Santa Luz Technical Report is based on open pit mining with production from three pits: one pit at the C1 deposit and two small pits at the Antas 3 deposit. Pit bench heights will be 10 m and be mined in two 5 m flitches with a safety berm every 10 m. The ore and waste rock will be drilled and blasted, loaded with front end loaders, and hauled to either a crusher or waste rock dump. Haulage distances from the open pit to the crusher area will vary, with an average haul distance of approximately 3.9 km for C1 and 2.5 km for Antas 3. Mining will be carried out by contractors and mine technical services will be provided by Santa Luz personnel. The mine will operate on a general production schedule of 24 hours per day, seven days per week. The mine life is nine years for C1, and six years for Antas 3. The maximum mining rate will be approximately 22.0 Mtpa of ore and waste mined including some overlap between deposits. The mine life is estimated to be nine and one-half years, plus one and one-half years of post-production processing of stockpiles, for a total of eleven years.

The existing plant is in reasonable physical condition, with some refurbishment required to ensure a smooth re-start of the operation. Additional grinding power will be installed to ensure design throughput and grind size are achieved. From late 2014 to the present, a metallurgical testing program has been conducted to evaluate the existing process facilities, determine the causes of the low gold recoveries, and develop a new flowsheet and recommendations for plant modifications to successfully process the carbonaceous material at Santa Luz. The results of the testing program led to a decision to develop a preliminary design and economic assessment based on a whole ore CIL flowsheet rather than the original flotation and concentrate leaching flowsheet. In late 2015, a new testwork program was established to assist in flowsheet optimization, including the comparison of a RIL circuit versus a conventional CIL circuit. With the addition of variability testwork, it was decided to move forward with a RIL process. A dedicated kerosene blinding circuit is included in the flowsheet to effectively use kerosene to deactivate the naturally occurring carbon that was the main cause for the gold recovery problems. The design will utilize as much existing equipment as possible and either add or modify equipment as required. The process has been determined to now include: primary and secondary crushing; primary semi-autogenous grinding mill grinding; secondary grinding using a conventional ball mill; gravity concentration; cyclone classification; kerosene pre-treatment in a dedicated circuit prior to RIL leaching; whole ore RIL leaching; cyanide destruction; resin acid washing, elution, and resin regeneration; electrowinning of the gold; doré casting; TSF, which has been geosynthetically lined, will be used for storage of whole ore leach tailings; water storage facility will be used for storage of raw water.

The administrative buildings, such as offices and mess hall, must be moved from their current position to allow for the development of the Antas 3—North pit. Permitting and Compliance Santa Luz maintains operational licences with several conditions that comprise monitoring and mitigation actions to compensate all environmental and social impacts, such as monitoring water quality, noise levels, and particulate matter. In the years since the shutdown of the original project, Santa Luz has maintained compliance with the general conditions established by the Instituto do Meio Ambiente e Recursos Hidricos (INEMA), as demonstrated by several environmental reports. Equinox Gold requested the renewal of its operating licences following the requirements of Brazilian law, where the renewal application must be submitted at least 120 days before the expiration date. This means its permits are valid until the publication of the license is renewed. Equinox Gold has obtained a fauna management licence and a new water permit to its operating licence considering the future operational process, which includes constructing the processing plant and the TSF expansion.

Annual Information Form - 98 - As part of the Santa Luz restart, tree deforestation licences were requested to support the TSF and water storage facility (WSF) raises and the Antas 3 pit expansion. In the medium term, additional environmental and social (E&S) studies may be necessary if the mining area exceeds the limits outlined in the current operational licences. In this case, the company will consult INEMA regarding the required E&S studies to obtain the necessary installation licences. Yamana previously committed to several community concessions to the original nearby village of Nova Esperança, including village relocation, community compensation, and other environmental considerations, for a total of R$20.6 million. The new village was completed in 2018. Since 2019 and up to June 30, 2020, Santa Luz spent an additional $0.25 million in community concessions. Yamana implemented a series of programs, such as Open Doors, partnership seminars, environmental education programs, and lectures in the schools and communities in the vicinity of Santa Luz, which have been continued to date by Equinox Gold. Equinox Gold has not identified any significant issues with local communities. Economic Analysis The economic analysis contained in the Santa Luz Technical Report is based on Proven and Probable Mineral Reserves only. The after-tax cash flow projection is summarized in the table below and is based on the open-pit LOM production schedule and capital and operating costs. Table 6: Santa Luz Cash Flow Summary ($1,500/oz Au) Description Value After-tax IRR 57.6% After-tax NPV at 0.0% discount $436.0 M After-tax NPV at 5.0% discount $305.1 M After-tax NPV at 8.0% discount $248.1 M Revenue and Costs • Approximately 7,400 tpd of ore processed (approximately 2.7 Mtpa). • Processing gold recoveries of 84% were used in the cash flow for a blended feed of high carbonaceous material, low carbonaceous material, and dacitic ore. Gold recovery for dacites with high sulphides is also projected to be 84%. • Metal prices for cash flow: $1,500/oz Au. • Salvage value of $15 million was applied to equipment or infrastructure at the end of the LOM. • 9.5-year project life during production. • Yearly revenues were calculated by subtracting the applicable refining charges and transportation costs ($10/oz) from the payable metal value generated by carbonaceous and dacitic ore and $177/oz from dacites with high-sulphide ore. • Revenue is recognized at the time of production. • Production schedule includes only Proven and Probable Mineral Reserves costs. • There are 6.9 Mt mined excluding stockpile rehandle as pre-stripping prior to the start of commercial production. • Unit operating costs for mining, processing, rehandle, grade control, and G&A were applied to determine the overall yearly operating cost. • Closure costs for the Project have been estimated at $8.8 million and these costs are included in the cash flow. • Initial capital cost totals $103.1 million. • Local currency denominated capital and operating costs are based on a nominal exchange rate of R$5.00:US$1.00. • Project LOM AISC is $877/oz.

Annual Information Form - 99 - Royalties An existing royalty agreement with the Federal Government for 1.5% gross revenue, and another agreement for 1% gross revenue with COSIBRA, was included in the cashflow and pit optimization analysis. An additional 2% royalty was included for the CBPM area of the C1 deposit, which represents a royalty on 397,810 oz in the production schedule. Subsequent to the date of the Santa Luz Report, the COSIBRA royalty was increased to 1.375% of gross revenue. Taxation For the calculation of income taxes, it has been assumed that a government economic stimulus program mining tax incentive would be approved for the duration of the LOM, which results in an income tax rate of 15.25%. An average rate of 9.25% was assumed for operating and capital costs subject to Brazilian federal value-added-taxes and 12% was assumed for items subject to state value-added taxes. Cash Flow Analysis The financial model was established on a 100% equity basis, which does not include debt financing and loan interest charges. Considering the Project on a stand-alone basis, the undiscounted after-tax cash flow totals $436.0 million over the LOM. The after-tax NPV at a 5% discount rate is $305.1 million, with an IRR of 57.6%.

Annual Information Form - 100 - Other Relevant Data and Information SLR updated a PEA-level study of the potential to exploit the Mineral Resources below the C1 open pit using underground mining methods. The C1 Underground resources are a proximal down-dip extension of the Mineral Resource exploited by the C1 open pit. The C1 Underground Mineral Resources in the PEA are summarized in the following table. Table 8: Santa Luz C1 Underground Mineral Resource Category Tonnes (‘000s) Grade (g/t Au) Contained Gold (oz) Measured 121 1.94 7,561 Indicated 5,913 2.55 484,066 Measured & Indicated 6,034 2.53 491,627 Inferred 6,560 2.19 461,367 Note: 1. CIM Definition Standards (2014) were followed for Mineral Resources. 2. Underground Mineral Resources are reported at a cut-off grade of 1.5 g/t Au. 3. Bulk density of 2.70 t/m3 used. 4. No minimum thickness was used in the resource estimation. 5. Mineral Resources are estimated using a gold price of $1,500/oz. 6. Totals may not add due to rounding. Host rocks to the underground resource include carbonaceous metasedimentary rocks, dioritic and dacitic intrusive rocks, and metavolcanic rocks. Most of the underground resource is classified as carbonaceous breccia. The mineralization style is quartz-carbonate-sulphide veins and breccia fillings hosted in a major, district-scale shear zone, typical of orogenic gold deposits. The shear zone is north to northeast trending and dips at 30° to 40° to the west. The shear zone and mineralization range in thickness from several metres to over twenty metres. The C1 Underground Mineral Resources considered in this study exist in four separate mining zones (A, B, C, and F). The largest is the B-Zone. Primary and secondary long hole stoping using paste backfill is considered the most practical and economic method for extracting the C1 Underground Mineral Resources. The design anticipates a nominal 2,500 tpd underground long hole mining operation using cemented paste backfill to allow for maximum extraction of the deposit. Over the potential 9.5-year LOM, a total of 7.1 Mt of mill feed would be extracted at a grade of 2.65 g/t Au. The preliminary development access and mining method design for the C1 Underground is based on current practices at Equinox Gold’s Fazenda Brasileiro mining operation located 115 km by road southeast of Santa Luz. SLR has utilized the same development heading profiles, stope drilling, blasting patterns and mobile equipment fleet for the C1 Underground as are in use at the Fazenda Brasileiro mine. Unit productivities (except for development) and unit costs for all component development and stoping activities (except for backfilling) proposed for the C1 Underground are based on the actual Fazenda Brasileiro mine 2016 and 2017 results.

Over the expected 9.5-year LOM, the C1 Underground is forecast to contribute a total production of 511,000 oz Au. A large proportion of the tailings generated from the processing of C1 Underground mill feed will be returned underground as paste backfill for the mined-out stopes. Paste fill production is estimated at 5.1 Mt. The remaining tailings (2.0 Mt) will be placed in the existing TSF. The estimated pre-production capital cost for the C1 Underground is $74.1 million and the total project capital is $98.3 million, including sustaining and closure capital. The estimated operating cost is $50.28/t. The key project parameters, based on a foreign exchange rate of R$5.00:US$1.00, are shown in the following table.

The economic analysis of the C1 Underground is based, in part, on Inferred Resources, and is preliminary in nature. Inferred Mineral Resources are considered too geologically speculative to have mining and economic considerations applied to them and to be categorized as Mineral Reserves. Additional drilling and technical studies will be required to convert the C1 Underground Mineral Resources to Mineral Reserves. There is no certainty that the results contemplated in the PEA will be realized.

Costs are based on whether the material being processed is stockpiled or in situ material. Cost estimates in the tables above are based on the Santa Luz mine plan and Equinox Gold’s current estimates as of December 31, 2023. Costs in individual years may vary significantly as a result of, among other things, current or future non-recurring expenditures, changes to input costs and exchange rates and changes to current mining operations or the mine plan. The current mine plan is based on existing Mineral Reserves. Ongoing exploration and analyses at operating mines are conducted with a view to identifying new Mineral Resources and upgrading existing Mineral Resources to higher confidence levels and potentially into new Mineral Reserves. If new Mineral Reserves are successfully identified, it may alter the current mine plan and potentially extend the mine life.

Annual Information Form - 103 - Recent Exploration, Development and Production Exploration The 2023 surface exploration program at Santa Luz was completed in Q3 2023 and included 7,630 m of RC drilling and 2,064 m of core drilling. Drilling focused on the near-mine Mansinha South deposit and three regional targets. Ongoing exploration activities include a regional geological mapping and prospecting campaign. Planned exploration at Santa Luz in 2024 includes 7,550 m of drilling focused primarily on regional targets. Development During 2023, sustaining capital totaled $7.2 million, primarily relating to a tailings storage facility raise. Non- sustaining capital expenditures totaled $3.0 million, primarily relating to exploration. The focus at Santa Luz in 2024 is on improving steady state plant throughput at design capacity to 2.5 million tonnes per year, and increasing recoveries, with the objective of achieving recovery of 73% or more for the second half of 2024. Budgeted sustaining expenditures at Santa Luz of $17 million in 2024 relate primarily to a $7 million TSF raise. Budgeted non-sustaining expenditures of $4 million in 2024 primarily relate to exploration. Production Santa Luz produced a total of 57,182 ounces of gold during 2023 at a cash costs of $1,681 per ounce and AISC of $1,834 per ounce. Santa Luz production guidance for 2024 is 70,000 to 80,000 ounces of gold, with cash costs of $1,495 to $1,595 per ounce and AISC of $1,720 to $1,820 per ounce.

Annual Information Form - 104 - Greenstone Project Greenstone is a development-stage gold project located in Ontario, Canada. In late 2016, a feasibility study was completed on the Greenstone open-pit deposit. In January 2021, Premier Gold Mines Limited (Premier), a wholly-owned subsidiary of Equinox Gold, updated the feasibility study and filed the Greenstone Technical Report. Equinox Gold acquired a 60% interest in April 2021 through its acquisition of Premier (50% interest) and subsequent purchase of an additional 10% from Orion. Greenstone is being advanced in a 60/40 partnership between Equinox Gold and Orion through their respective interests in Greenstone Gold Mine GP Inc., which manages the project. Construction commenced in Q4 2021, and the project is on track to pour gold in the first half of 2024. Greenstone will be an open pit mine with the expectation of producing more than 5 million ounces of gold over an initial 14-year mine life. Gold production for the first five years of operations is estimated at more than 400,000 ounces annually with life-of-mine production expected to average 360,000 ounces annually, with 60% attributable to Equinox Gold. Unless otherwise indicated, the information that follows relating to Greenstone is based on, derived substantially from, and in some instances is a direct extract from, the Greenstone Technical Report. Technical information disclosed since the effective date of the Greenstone Technical Report has been updated under the supervision of the Qualified Persons noted in the section ‘Interest of Experts’ on page 151. The information below is based on assumptions, qualifications and procedures that are set out only in the Greenstone Technical Report and reference should be made to the full text of the Greenstone Technical Report which is filed on the SEDAR+ profile of Premier (a wholly-owned subsidiary of Equinox Gold) at www.sedarplus.ca, on the EDGAR profile for Equinox Gold at www.sec.gov/EDGAR, and which is also available on Equinox Gold’s website at www.equinoxgold.com. Property Description, Location and Access The Greenstone Gold Mine Property (the GGM Property) is situated in the Thunder Bay Mining Division of Ontario. The GGM Property includes three blocks of contiguous claims known as the Hardrock, Brookbank and Viper areas, over a distance of more than 100 km located along, or in close proximity to, the Trans-Canada Highway between the towns of Beardmore and Longlac, Ontario. The Hardrock claim group includes the Hardrock, Key Lake and Kailey Deposits. The Brookbank claim group hosts the Brookbank, Cherbourg and Fox Ear deposits and the Irwin prospect. The Greenstone project (the Greenstone Project) is located within the southeast portion of the Hardrock claim block. The GGM Property consists of a contiguous block of patented claims, mining leases, licences of occupation and cell claims covering a total area 39,072.1 ha, of which 15,862.7 ha relates to Hardrock claims, all as summarized in the Greenstone Technical Report. All claims, leases and licences of occupation are beneficially held by GGM on behalf of Greenstone Gold Mines LP (the Partnership), subject to terms of applicable agreements. A leasehold patent of mining rights or of surface rights, or combination thereof, is a conveyance or grant of possession of land for a set length of time, and usually subject to rent payments. The Greenstone project is accessible year-round via paved roads from Geraldton or Highway 11. The following section describes the Greenstone project within the Hardrock claim block. Additional information regarding Key Lake, Brookbank, Kailey and Viper areas is available in the Greenstone Technical Report.

Annual Information Form - 105 - Location The Hardrock deposit area is located in the townships of Errington and Ashmore on NTS sheet 42E/10, approximately 4 km south of the town of Geraldton. The approximate geographic centre coordinates of the Hardrock deposit resource area are 49°40'47”N and 86°56'32”N (UTM coordinates: 504175.9E and 5503024N, NAD 83, Zone 16).

In October 2018, a mining lease was granted over CLM 535, which covers the southern part of the Greenstone Project area. The lease, LEA-109765, is subject to renewal in 2039. In December 2016, GGM acquired the surface rights for the following patented claims from Tombill Mines Ltd. – TB 10604 to TB 10608, TB 11879, TB 11885, TB 11886, and TB 11888 located in Errington and Ashmore townships. Permits Permits are required to undertake surface stripping and trenching, and drilling. The Greenstone Technical Report lists all the permits required to construct and operate Greenstone. Generally, the permits required for construction and early operation have been obtained. Additional information regarding certain risks applicable to the Greenstone Project can be found in Section 25.2.1 of the Greenstone Technical Report. History and Exploration There are several past producing gold mines on the GGM Property, including the Hard Rock, MacLeod-Cockshutt, Mosher (all later combined as the consolidated Mosher), Little Long Lac, Bankfield, Jellicoe and Magnet mines. Reference should be made to the Greenstone Technical Report for a detailed description of the applicable exploration and production history. The Greenstone Project has been the subject of extensive exploration by a number of companies since gold discovery was first made between 1916 and 1918. In 2007, Premier began assembling the current property. Results of 1,629 drill holes were included in the 2016 feasibility study. A detailed chronological summary of the historical post- production work carried out on these mines since Premier’s acquisition is provided in Table 1.

Annual Information Form - 107 - Geological Setting, Mineralization and Deposit Types Geology The Greenstone Project lies within the granite-greenstone Wabigoon Subprovince of the Archean Superior craton in eastern Canada. The Wabigoon Subprovince, averaging 100 km wide, is exposed for some 900 km eastward from Manitoba and Minnesota, beneath the Mesoproterozoic cover of the Nipigon Embayment, to the Phanerozoic cover of the James Bay Lowlands. The Wabigoon Subprovince can be subdivided into western greenstone-rich domains in the Lake of the Woods-Savant Lake and Rainy Lake Areas, a central dominantly plutonic domain, and an eastern greenstone-rich domain in the Beardmore-Geraldton Area. The Hardrock property is located within the Beardmore-Geraldton Greenstone belt that contains several narrow, east-west striking sequences of volcanic and sedimentary rocks of Archean age. The southern edges of these sequences are spatially related to the through-going, major structural discontinuities thought to be thrust faults that have imbricated the sedimentary sequences. In the Geraldton area, most of the gold mines and a number of gold showings occur within or in proximity to the Bankfield-Tombill Deformation Zone (also known as the Barton Bay Deformation Zone), a zone of folding and shearing up to 1 km wide. The southern limit of the Tombill-Bankfield Deformation Zone is marked by the Tombill-Bankfield Fault, a zone of intense shearing up to 12 m wide. In the immediate Geraldton area, the dominant rock types are clastic sediments (greywacke and arenite), oxide facies iron formations (BIF) and minor mafic metavolcanics. There are a number of younger intrusives, including an albite-rich porphyry unit (Hard Rock Porphyry) that is spatially associated with much of the gold mineralization on the Hard Rock, MacLeod-Cockshutt and Mosher Mines. Significant gold mineralization is also often spatially associated with BIF. In the case of the Little Long Lac Mine, gold mineralization is primarily hosted by an arkosic unit. The gold mineralization occurs in a variety of host rocks and the style of mineralization is partly a function of the host rock. While the location and overall orientation of the ore bodies appear to have been largely structurally controlled, the deformation of the ore bodies has not been as intense as that of the host rocks. Nevertheless, there are areas where local folding and boundinage of mineralized veins is apparent. Additionally, there are strong secondary controls that influence the extent and intensity of gold mineralization such as the competency contrast between host rocks (e.g. the Hard Rock Porphyry and its contacts with either wacke or BIF) and the chemical character of the host rocks (e.g. oxide facies BIF being replaced by sulphides). Intrusive rocks include the Hard Rock porphyry, diorite, gabbro, and diabase dykes. It is of interest that the Hard Rock porphyry seems to be sill-like in nature, even though it is tightly folded and the contacts between it and the sedimentary units are often highly deformed. The general scale and folding pattern of the porphyry very closely matches the geometry of the conglomerate unit that occurs in the vicinity of the Hard Rock and MacLeod Cockshutt Mines. Mineralization Most mineralized occurrences in the Hardrock deposit area lie in a zone of deformation to the immediate north of, and genetically linked to, the Tombill-Bankfield Deformation Zone. This zone of deformation varies from 600 to 100 m in total width, while the crush zone of the Tombill-Bankfield Fault proper ranges from metres to hundreds of metres in width. Gold mineralization is associated with D3 brittle shear zones and folds overprinting regional F2 folds. The plunge of the mineralized zones is parallel to F3 fold axes and to the intersection of D3 shear zones with F2 and F3 folds. On a sub-province scale, regional folds cut by D3 dextral shear zones are promising targets for discovering the next generation of large gold deposits.

Annual Information Form - 108 - The interpretation of the mineralized zones by GMS is based on a litho-structural model developed by InnovExplo but greatly simplifies the domains. As compared to the 2016 Feasibility block model, some wide domains that encompassed significant amounts of internal dilution have been re- interpreted, such that higher grade portions have been made more distinct. In the updated model, lithological domains and mineralized zones are located inside three areas. A North Domain consisting of a refolded (F3 overprinting F2) sequence of BIF and greywacke, with minor porphyry and gabbros. A Central Domain consisting mainly of an undifferentiated greywacke sequence and a mineralized portion of this greywacke, defined as the Mineralized Central Wacke, which are both likely sheared and folded. Three mineralized zones have been defined within the Central Domain to constrain zones of higher-grade gold mineralization inside the Mineralized Central Wacke. A South Domain characterized by a tightly folded (F2) stratigraphic sequence. Five mineralized zones have been defined within the South Domain, in which gold mineralization appears primarily associated with the “main” anticline (Hardrock Anticline) and preferentially within both BIFs. Zones which are categorized as quartz-carbonate stringer mineralization include F-Zone, F2-Zone, A-Zone, SP-Zone, Central-Zone and Tenacity Zone. Mineralization within these zones generally consists of a series of narrow, tightly asymmetrically folded gold-bearing quartz-carbonate stringers, which are usually attenuated, transposed and dislocated in hook-like segments. The stringers are accompanied by a gold- bearing quartz-sericite-pyrite (±arsenopyrite) alteration halo about the stringers. It is the accumulation of a number of stringers and associated alteration halos that constitutes the zones. Individual stringers and their associated alteration haloes within the mineralized zones are often high grade with minute flecks and clusters of visible gold. Assay results of up to, and often greater than, 30 g Au/t are attainable from some stringers. Overall, zones having average grades of 4 g Au/t as individual stringers are too narrow and discontinuous to consider mining as separate higher grade zones. Zones that are categorized as sulfide replacement mineralization include the North 1, North 2 and North 3 zones, and the SP-Zone. The nature of the mineralization within these zones is best understood from the historical work completed on the North 1-Zone. Mineralization within these zones occurs as variable pyrite, arsenopyrite and pyrrhotite replacement of Fe oxide at the margins of quartz veins, within the hinge zones of folded BIFs. The auriferous sulfide replacement appears to have migrated outwards along the iron oxide bands from gold-bearing quartz-carbonate stringers occupying brittle axial planar tension fractures. This replacement mineralization yields grades of 7 g Au/t or greater. Deposit Types The gold orebodies at the Greenstone Project are one of the type examples of BIF-hosted gold deposits. The following sub-types are recognized and are present in the Greenstone Project: non-stratiform deposits and Greenstone-hosted quartz-carbonate vein deposits. Drilling Between May 26, 2014 and November 18, 2015, GGM added 157 diamond drill holes (DD) on the Hardrock Deposit for a total of 54,027 m. One diamond drill hole (MM043) included in the 2014 Mineral Resource Estimate (MRE) was also deepened, from 456 m to 655 m, representing a total of 199 m of new meterage. Seventy-nine (79) historical Diamond drill holes were re-sampled to add new assay results in the 2016 MRE. These holes represent a total of 8,733 m and 6,411 samples included in the 2016 Greenstone Project database. A collar re-survey campaign, using the Trimble RTK survey instrument, took place in the summer of 2014 for a total of 536 drill holes for which casing was found.

Annual Information Form - 109 - For the 2018 and 2019 drilling programs, the site surveyor and geologists spotted the reverse circulation grade control (RCGC) and blast holes using a Trimble device with RTK base station using the coordinates planned by GMS or GGM. In the event of unstable or poor ground access, the hole was moved a few metres. The drill is aligned to the proper azimuth and dip using a Reflex Astronomic Positioning System. Down-hole surveys were taken every 30 m in the diamond drill holes using a Reflex EZ-GyroTM instrument. The 2018 RCGC and down-the-hole (DTH or blast hole) drilling campaigns were resource definition programs, designed to de-risk the project and to focus on increasing the confidence level in the mineral resources in the initial years of production. The drilling took place on five key areas. Area 1 was not accessible due to flooding. From May 24, 2018 to September 6, 2018, 405 RCGC drill holes were completed totaling 19,995 m on the property based in Geraldton, Ontario. The program targeted five areas which were defined by their geographic and lithological properties. RCGC holes were planned with a spacing of 10 m in the North to South direction and 20 m in the East to West direction. On average, the RCGC holes were 50 m deep and had a dip of -50 degrees, oriented due North or South and planned within five significant mineralized areas. The results obtained from the RCGC drilling program confirmed the grade continuity in all areas. All RCGC material (chip trays from logging, rejects and representative samples) are stored on site in sea containers at GGM’s Magnet Property. In July 2018, 62 blast holes totaling 535 m were drilled by Epiroc. The program occurred concurrently with the RCGC drilling program and aimed to further increase the confidence in the mineral resources in the F-Zone, headframe and porphyry hill area to test the performance and viability of blasthole drilling for the Hardrock deposit. The blast holes were planned with a tighter spacing of approximately 6 m in the North to South and East to West directions. The blast holes were on average 10 m deep and drilled vertically. The 2019 drilling program consisted of 76 RCGC drill holes totaling 5,946 m of which 5,527 m were assayed, and 54 NQ size diamond drill holes for 12,108 m of which 10,470 m was assayed. These were resource definition and grade control programs, designed to provide better definition in high potential areas of the Greenstone Project and to increase the confidence level in the Mineral Resource in the initial years of production. RCGC holes were planned with a spacing of 20 m in the North to South direction and 20 m in the East to West direction. On average, the RCGC holes were 100 m deep and had a dip of -50 degrees, oriented due North or South. The 2019 drilling program outcomes are detailed below: • RCGC drilling was spatially limited to the SP-Zone and F-Zone to confirm grade continuity for benches 4 to 7; • 70 m vertical (or 7 benches) were drilled at an average spacing of 20 m x 20 m inside an area already drilled in 2018; • Diamond drilling intersected the majority of mineralized domains, and infilled gaps in the drill spacing in the central portion of the pit; • Grades in drilling compared well with block model grades predicted in a 2018 interim block model. During the Hardrock site visit, the responsible Qualified Persons reviewed drilling procedures, observed RC drilling, and inspected sampling facilities and core storage facilities. Core recovery is excellent throughout the deposit, and recoveries from near-surface RC drilling were deemed acceptable. Drilling methods (both diamond drilling and RC drilling) adhered to industry standard practises, and representative samples were obtained.

Annual Information Form - 110 - Sampling, Analysis and Data Verification Laboratories The Geraldton facility belonging to Activation Laboratories Ltd (Actlabs Geraldton) was used for the entire drilling and channelling programs. Actlabs Geraldton has received ISO 9001:2008 certification through Kiwa International Cert GmbH. Actlabs Geraldton is an independent commercial laboratory. All re-assaying of batches (pulps) was undertaken at ALS-Chemex in Thunder Bay. ALS-Chemex laboratory is part of the ALS Global Group and has ISO 9001 certification and ISO/IEC 17025 accreditation through the Standards Council of Canada. ALS-Chemex is an independent commercial laboratory. Quality Control Sample Preparation by GGM All Quality Assurance/Quality Control (QC) samples are prepared and bagged in advance by GGM personnel. The GGM employee in the core cutting facilities places one half of the ticket into a bag with the sample and staples the other half in the box. One half of each quality control sample ticket is placed in the appropriate type of control sample bag, which was prepared beforehand. A list of quality control samples and their numbers/locations is posted on the wall in the core logging facility (core shack) and regularly updated by GGM personnel. Five to seven samples are placed in a rice bag and the contents identified on the outside of the bag. Each bag and its contents are recorded on a notepad and placed in a plastic holder once complete. These slips are picked up each morning by a GGM employee and recorded in an Excel spreadsheet. Once the batches are complete, GGM personnel deliver the bags to Actlabs Geraldton and no third party is involved in transportation. Samples selected for analysis are sent in batches of 34 samples. Each purchase order covers one batch of 34 samples consisting of: • 30 regular samples; • 1 field duplicate sample; • 1 field blank; • 1 Certified Reference Material (CRM or standard) with a low gold value; • 1 CRM with a high gold value. As a quality control check, Actlabs Geraldton adds a 35th sample to every field batch received in the form of a coarse duplicate of the last regular sample (the 30th sample), constituting a second pulp prepared from the reject. The quality of the reject is monitored to ensure that proper preparation procedures are used during crushing. For the fusion process, Actlabs Geraldton adds seven additional quality control samples (two analytical blanks, two CRMs and three pulp duplicates), bringing the fusible batch to a total of 42. The pulp duplicates are necessary to ensure that proper preparation procedures are used during pulverization. At Actlabs Geraldton, the maximum furnace charge of 42 samples ensures that GGM samples are not mixed with others. Fire Assay Procedures (Actlabs Geraldton) Samples (50 g each) are sent to the fire assay area numbered and in order (usually 1 to 34+1). A rack of 42 crucibles is then labelled with an assigned letter code and numbered one to 42. The mixture is placed in a fire clay crucible. The mixture is then preheated to 850°C, intermediate at 950°C and finished at 1,060°C, with the entire fusion process lasting sixty minutes. The crucibles are then removed from the assay furnace and the molten slag (lighter material) is carefully poured from the crucible into a mould, leaving a lead button at the base of the mould. The lead button is then placed in a preheated cupel which absorbs the lead when cupelled at 950°C to recover the Ag (doré bead) + Au. The entire Ag doré bead is dissolved in aqua regia and the gold content is determined by atomic absorption (AA) finish (1A2-50 code).

Annual Information Form - 111 - On each tray of 42 samples there are two blanks, three sample duplicates and two certified reference materials, one high and one low (QC = 7 out of 42 samples). All samples assaying grades over 5.0 g Au/t with AA were re-run with gravimetric finish to ensure accurate values. After the fire assay procedures, Au is separated from the Ag in the doré bead by parting with nitric acid. The resulting gold flake is annealed using a torch. The gold flake remaining is weighed gravimetrically on a microbalance. Fire Assay Procedures with Gravimetric or AA Finish (ALS-Chemex Thunder Bay) The fire assay technique uses high temperature and flux to “melt” the rock and allows the gold to be collected. Lead formed from the reduction of litharge is traditionally used as the collecting medium for silver and gold. The test sample is intimately mixed with a suitable flux that will fuse at high temperature with the gangue minerals present in the sample to produce a slag that is liquid at the fusion temperature. The liberated precious metals are scavenged by the molten lead and gravitate to the bottom of the fusion crucible. Upon cooling, the lead button is separated from the slag and processed in a separate furnace for a high temperature oxidation (cupellation) where the lead is removed, leaving the precious metals behind as a metallic bead called a prill. Traditionally, this prill was then partially dissolved in nitric acid (parted) to remove silver and the remaining gold determined by weighing (gravimetry). Alternatively, the prill can be dissolved in a mixture of hydrochloric and nitric acid (aqua regia) and the concentration determined by spectroscopic methods. For the AA finish method, a pulp sample is fused with a mixture of lead oxide, sodium carbonate, borax, silica and other reagents as required, inquarted with 6 mg of gold-free silver and then cupelled to yield a precious metal bead. The bead is digested in 0.5 ml dilute nitric acid in the microwave oven. The 0.5 ml concentrated hydrochloric acid is then added, and the bead is further digested in the microwave at a lower power setting. The digested solution is cooled, diluted to a total volume of 4 ml with de-mineralized water, and analyzed by AA spectroscopy against matrix- matched standards. For the gravimetric finish method, a pulp sample is fused with a mixture of lead oxide, sodium carbonate, borax, silica and other reagents in order to produce a lead button. The lead button containing the precious metals is cupelled to remove the lead. The remaining gold and silver bead is parted in dilute nitric acid, annealed and weighed as gold. Silver, if requested, is then determined by the difference in weights. At the ALS-Chemex laboratory, the batch size for all fire assay method is 84 including six internal QC. Therefore 78 client samples can be done per batch. The maximum furnace charge of 78 client samples ensures that GGM samples are not mixed with others. QP Conclusions A statistical analysis of the QC data provided by GGM did not reveal any significant analytical issues. The responsible Qualified Persons are of the opinion that the sample preparation, analysis, QC and security protocols used for the Greenstone Project follow generally accepted industry standards and that the data is of sufficient quality to be used for Mineral Resource estimation. Data Verification This section summarizes data verification procedures for the updated MREs. For the Hardrock deposit, as the 2016 MRE database formed the basis of the 2019 MRE, data verification procedures for the 2016 MRE are still valid and are described in the Greenstone Technical Report. Data verification for the Greenstone Project consisted of numerous site visits to monitor drilling activities, reviewing new drill hole data merged into the 2016 MRE database, reviewing new voids, and the review of new lithology, alteration and structural data. Finally, the verification also included a comparison of the RCGC assay grades versus the diamond drilling assay grades on section.

Annual Information Form - 112 - Overall, the responsible Qualified Persons are of the opinion that GGM’s protocols for drilling, sampling, analysis, security, and database management meet industry standard practices. The 2019 data verification process demonstrated the validity of the data and protocols for the Greenstone Project. The responsible Qualified Persons consider the GGM database to be valid and of sufficient quality to be used for the Mineral Resource estimation. Data Verification for Tailings Storage Facility Geotechnical investigations were undertaken to characterize the sub-surface conditions along the TSF dam footprint during 2014, 2015, 2016, 2018 and 2019 which included test pitting, borehole drilling, cone penetration test and field vane shear tests. Disturbed and undisturbed samples were extracted and tested for various index, strength parameters in an approved laboratory. The stratigraphic and strength information of the subsurface units were reviewed, interpreted and utilized in the design of the TSF dams. Extensive geotechnical investigations in the TSF dam footprint have facilitated the assessment of design parameters required for the TSF dam design. Mineral Processing and Metallurgical Testing The process design criteria have been established based on testwork results, GGM and vendor recommendations or requirements and industry practices. Between 2011 and 2013, mineralogy, grindability and gold recovery testwork was performed by SGS Lakefield Research Limited (SGS Lakefield) and McClelland Laboratories Inc. (McClelland). The SGS Lakefield testwork showed that the ore is composed mainly of quartz and plagioclase with minor amounts of pyrite and arsenopyrite, gold occurs mainly as native gold, the ore is in the category of medium hardness to moderately hard, a portion of the gold can be recovered by gravity concentration and gold can be recovered to a bulk flotation concentrate. The subsequent McClelland testwork showed that gold recovery increased with finer grind size and was unaffected by cyanide concentration. In the course of the March 2014 Preliminary Economic Assessment and 2016 feasibility study, additional testwork was carried out by SGS Lakefield, JKTech Pty Ltd. and FLSmidth. Primarily, high pressure grinding roll (HPGR) tests confirmed the ore amenability for high pressure grinding, and facilitated equipment selection and operating cost estimation. Grindability, head grade determination, mineralogy, magnetic separation, gravity recovery, flotation, cyanidation, cyanide destruction, solid-liquid separation and other tests were completed. Additional thickening and rheology testwork were carried out to determine the sizing and operating parameters of a pre-leach thickener. The HPGR testing program included laboratory scale tests to determine the amenability of the ore to HPGR milling and yield preliminary sizing data; abrasion tests to predict the service life of the rolls and a large- scale pilot plant test to size the equipment. Bond grindability testing was performed to evaluate the Ball Work Index reduction of the HPGR product compared to the feed. A detailed comminution trade-off study recommended two-stage crushing followed by HPGR and ball milling over crushing followed by semi-autogenous milling and ball milling, to reduce throughput risk and increase energy efficiency. In the detailed engineering phase additional leach test work was carried out on near-surface samples from the 2018 drilling campaign to characterize gold recovery, oxygen consumption, solid-liquid separation and rheology. A multivariate linear regression analysis was used to estimate gold recovery based on ore grade and mineralogical composition. The results of the cyanidation tests conducted on composites were used as the basis for the analysis. The residual gold grade from the cyanidation testwork was found to be highly correlated to the gold, arsenic and sulphur head sample grades, and somewhat less on grind size. The gold recovery process for the Greenstone Project consists of a crushing circuit (gyratory and cone), a grinding circuit (HPGR and ball mill), pre-leach thickening and cyanide leaching, a carbon in pulp (CIP) circuit, carbon elution and regeneration, electrowinning and gold refining,

Annual Information Form - 113 - cyanide destruction and tailings disposal. The plant is designed to operate at a throughput of 27,000 t/d. The process operation schedule is 24 hours per day, 365 days per year, with an overall availability of 92%. Gold production averages 414 koz for the first five years of production (from start of Year 1 to end of Year 5) with an average head grade of 1.45 g Au/t and an average metallurgical recovery of 91.2%. Mineral Resource and Mineral Reserve Estimates Mineral Resource Estimate (MRE) Since the previous MRE was released in 2016, substantial drilling has been conducted and was successful in de- risking the MRE in the early years of production. RCGC drilling on a 20 m (X) by 10 m (Y) spacing was undertaken in 2018 and 2019 targeting the first three benches of production, and also partially tested an additional four benches in certain areas. In 2019, diamond drilling was undertaken in areas identified as requiring infill drilling, and resulted in the validation of the new geological interpretation and confirmation of the grade continuity. The Greenstone Technical Report is based on an open pit mining scenario. The in-pit Mineral Resources at the Hardrock deposit are constrained within the design pit using a cut-off grade of 0.30 g Au/t. In addition to in-pit Mineral Resources, an underground Mineral Resource was estimated outside the open pit using a 2.0 g Au/t cut- off grade. Greenstone Project open pit and underground Mineral Resources are summarized in Table 2. The MRE covers a corridor of the Hardrock deposit with a strike length of 5.7 km and a width of approximately 1.7 km, down to a vertical depth of 1.8 km below surface. Mineralized zones were interpreted in 3D using Leapfrog GEO™ software based on a litho-structural model and the drill hole database. The drill hole database used in the estimate contained 312,408 sampled intervals from 696,125 m of diamond drilling in 1,682 holes, and 11,871 assays from 25,961 m of reverse circulation drilling in 481 holes. Channel samples were not used in the estimation. Mineral Resources were estimated by applying a minimum true thickness of 3.0 m and using the grade of the adjacent material when assayed or a value of zero when not assayed. High-grade capping on raw assay data was established on a per zone basis. Compositing was conducted on drill hole sections falling within the mineralized zones (composite = 2 m). Mineral Resources were estimated using 3D block modelling and 3-pass ID3 interpolation with high-grade restraining. Mineral Resources were classified as Measured in areas within 15 m of the RCGC drilling and Indicated in areas where the maximum distance to drill hole composites was less than 35 m for blocks interpolated in Passes 1 and 2 (using a minimum of two drill holes). Mineral Resources were classified as Inferred in remaining blocks interpolated during Passes 1 to 3. Lastly, all blocks in the underground resource estimated in Pass 1 to 3 in the external grade shell domain (500, 501 and 506) were downgraded to Inferred category. A grooming step was undertaken on the classification to ensure that the Resource category is coherent for mine planning purposes.

The responsible Qualified Persons are not aware of any known environmental, permitting, legal, title-related, taxation, socio-political, marketing or other relevant issue that could materially affect the MRE. 9. 2014 Canadian Institute of Mining, Metallurgy and Petroleum (CIM) definitions were followed for Mineral Resources. Mineral Reserve Estimate The Mineral Reserve for the Greenstone Project was estimated based on the open pit mining scenario proposed in the Greenstone Technical Report and is summarized in Table 3. Table 3: Mineral Reserve Estimate (Open Pit) (100% basis) Category Diluted Ore Tonnage (kt) Gold Grade (g Au/t) Contained Gold (koz Au) Proven 5,623 1.28 232 Probable 129,700 1.27 5,307 Total P&P 135,323 1.27 5,539 Notes: 1. 2014 CIM definitions were followed for Mineral Reserves; 2. Effective date of the estimate is August 8, 2019; 3. Mineral Reserves are estimated at a cut-off grade of 0.35 g Au/t; 4. Mineral Reserves are estimated using a long-term gold price of USD 1,250/oz and an exchange rate of CAD : USD 1.30; 5. A minimum mining width of 5 m was used; 6. Bulk density of ore is variable but averages 2.78 t/m3; 7. The average strip ratio is 5.10:1; 8. Dilution factor is 17.2%; 9. Numbers may not add due to rounding. The Mineral Reserve estimate is consistent with the 2014 CIM definitions. As such, the Mineral Reserves are based on Measured and Indicated Mineral Resources (M&I), and do not include any Inferred Mineral Resources. Indicated Mineral Resources were converted in Probable Mineral Reserve and Measured Mineral Resource in Proven Mineral Reserve. The Inferred Mineral Resources contained within the mine design are classified as waste. Open pit optimization was conducted using Whittle software to determine the optimal economic shape of the open pit to guide the pit design process. The Mineral Reserve estimate includes a 17.2% mining dilution at an average grade of 0.13 g Au/t and a 1.5% ore loss factor.

Annual Information Form - 115 - Mining Operations Mining will be carried out using conventional open pit techniques with 10 m benches. An owner-mined open pit operation is planned with hydraulic shovels and mining trucks, including outsourcing of certain support activities such as explosives manufacturing and blasting. Production drilling of the 10 m benches will be by blast hole drill rigs with both rotary and DTH drilling capability. Blast holes are loaded with bulk emulsion. The majority of the loading in the pit will be carried out by two 29 m3 hydraulic face shovels, one 29 m3 hydraulic excavator, and two 30 m3 front-end wheel loaders. The shovels and loaders will be matched with a fleet of 216 t payload mine trucks. The presence of underground stopes was considered when designing the pits mainly for the void in the F-Zone, which is 150 m high and 30 m wide. Most of the other underground openings are backfilled with sand fill or rock fill. Mining of the Hardrock main pit will occur in five main phases preceded by a starter pit. Waste rock will be disposed of in five distinct waste dumps with four located around the pit and one further to the south. The open pit generates 689.6 Mt of overburden and waste rock (inclusive of historic tailings and underground backfill) over the life of mine (LOM) for an average LOM strip ratio of 5.1:1. The LOM plan details 12.9 years of mine production (from April of Year 1 to February of Year 14), preceded by a preproduction period of 20 months which includes a 4-month plant commissioning period (excludes crushing). Once the open pit is depleted, the process plant is fed for an additional 9 months from low-grade stockpiles. Commercial operations are scheduled for 13.7 years (from April of Year 1 to November of Year 14). Processing and Recovery Operations The plant will ramp-up to the nameplate capacity of 27,000 t/d in approximately one year (grind size of 80% passing (P80) 90 μm. The grinding circuit includes a HPGR, two identical ball mills and two identical gravity concentrators. The mill operation schedule is 24 h/d, 365 d/y with an overall availability of 92%. Crushing plant and processing plant equipment design factors allow for a margin of error in the sizing of the equipment. They are used in the calculations of the equipment feed rates and residence times. The key general process design criteria are presented in Table 4.

The service areas include reagent preparation, compressed air, oxygen plant and sulphur dioxide storage and distribution. The water management system covers all the fresh, reclaim, process, potable, fire and gland water storage and pumping. An onsite sewage treatment plant will process domestic wastewater, discharging to the environment. Tailings reclaim and collected contact water will be used for process water, with excess contact water treated and discharged to the environment. Infrastructure, Permitting and Compliance Activities Infrastructure General The Greenstone Project occurs in a district with active mines and processing facilities located at Hemlo and Timmins, Ontario and therefore has access to good transportation and regional mining related infrastructure. The Greenstone Project is located in close proximity to the Trans-Canada Highway 11, TransCanada Pipelines Limited Canadian Mainline (TCPL Mainline) natural gas pipeline, a Hydro One electrical substation and Geraldton hosts a municipal airport, which has a 1,500 m runway capable of accommodating large aircraft. Geraldton has its own potable water treatment system and water distribution network, which are proposed to be used for the Greenstone Project. General infrastructure for the Greenstone Project that will be constructed to support mining and processing will include: • Site access and haul roads; • Workshop and maintenance facility; • Warehousing for spare parts and reagents; • Administration building including a dry facility, gatehouse and parking area; • Explosive reagent storage; • Fuel storage and distribution; • Recycling and sorting facility; • Potable water and sewage systems; • Fire water systems; • Site security and fencing.

Annual Information Form - 117 - Existing infrastructure within the footprint of the property limits that will need to be relocated includes: • Trans-Canada Highway 11; • Existing Hydro One 115 kV station; • Ontario Provincial Police Station; • MacLeod High Tailings (portion covering the open pit mine); • Ontario Ministry of Transport patrol station. The existing Hydro One grid is insufficient for powering the processing facilities and associated infrastructure. A 65 MW natural gas-fired power plant will be constructed, with a designed capacity of 46.5 MW, which will include a natural gas pipeline originating from the existing TCPL Mainline pipeline directly to the site power plant. Water Management Two types of effluents will be generated during Greenstone Project activities: mine effluent and sanitary effluent. The water quality standards applicable to mine effluent are the Provincial Water Quality Objectives (PWQOs), Ontario Regulation (O.Reg.) 560/94-MISA Metal Mine Sector Effluent Criteria, and Federal Metal Mining Effluent Regulations (MMER) Effluent Criteria. The Assimilative Capacity Study conducted for the Greenstone Project identified discharge locations and proposed quality criteria for both mine and sanitary effluents discharging to the Southwest Arm of Kenogamisis Lake which are protective of the receiving environment. The effluent criteria proposed meet and exceed MMER and O.Reg. 560/94 criteria at end of pipe and the PWQOs for all parameters are met within a small mixing zone in the receiving waterbody. All collected mine water, surface runoff water and underground workings water will be directed through various runoff and seepage collection ponds to the centralized mine water Collection Pond M1, which is designed to provide buffer flows for mill make-up water and the effluent water treatment plant supply. The treated water is then released to the Southwest Arm of Kenogamisis. A seepage collection system will be installed to manage seepage from the Macleod historical tailings as an early project development activity. Runoff and seepage collection from the exterior of the TSF dams will be collected in a series of ponds and generally pumped back to the TSF for re-use in processing. In case there is surplus water, which cannot be pumped into the TSF, water will be treated prior to discharging to the environment. Tailings Storage Facility The TSF dams have been designed to meet the requirements of the Lakes and River Improvement Act Ministry of Natural Resources and the Canadian Dam Association guidelines (CDA) with a relatively low permeability core protected by filters and transition zones upstream of the main embankment, and constructed of geochemically benign mine rock. The TSF dam foundation was characterized by conducting extensive geotechnical investigations. A site-specific seismic hazard study was carried out for the seismic design of the TSF dams. The stability of the dams meets the target factors of safety required as per CDA. The TSF site is located approximately five kilometres southwest of the process plant site and was selected to minimize the disturbance to fish bearing water bodies, maximize the use of natural containment and optimize Greenstone Project economics. Prior to construction of the TSF, Goldfield Creek will be diverted around the north side of the TSF into a permanent channel designed to provide fisheries compensation. The site has a positive water balance, and as such, the TSF will be developed to minimize the surplus water requiring treatment. It is planned to complete tailings deposition early in one cell to allow for progressive rehabilitation and shedding of runoff from the system. Closure of the TSF involves lowering of the spillways and vegetation of the exposed beaches. Runoff will be directed through spillways constructed in natural ground when deemed suitable for discharge to the environment.

Annual Information Form - 118 - Permitting and Compliance Environmental baseline studies were initiated for the Greenstone Project in 2013 and were used to identify environmental constraints during the development of preliminary layouts and designs for the Greenstone Project. This included consideration of siting and layout of Greenstone Project infrastructure as well as consideration of design alternatives from an environmental management and approvals perspective. This environmental baseline was the basis for determining incremental changes and predicting environmental effects associated with the Greenstone Project. A final environmental impact statement / environmental assessment (EIS/EA) has been completed and approved by provincial and federal regulatory agencies. A conceptual Closure Plan was developed as part of the EIS/EA to provide an early opportunity to discuss the closure approach and initial costing. The Closure Plan has now advanced to a final version and was approved by the MENDM in January 2020. The results of the final EIS/EA, including implementing the identified mitigation measures, supports the conclusion that the Greenstone Project will not cause significant adverse environmental effects. There are no issues identified to date that would materially affect the ability of GGM to extract minerals from the Greenstone Project. Since completing the final EIS/EA, GGM has completed slight modifications of project components as detailed engineering advances, which form the basis for the final mine plan used for the Greenstone Technical Report. Active consultation with stakeholders (community members, agencies and interested parties) and Indigenous communities has been undertaken throughout Project planning and will continue as the Greenstone Project progresses through permitting and detailed engineering. GGM has established Long Term Relationship Agreements (LTRAs) with the five local Indigenous communities. The agreements establish increased clarity regarding GGM’s ability to develop the Greenstone Project and the Indigenous communities’ opportunity to benefit from future mining opportunities in the region, including the potential to extend the life of the Greenstone Project. Provincially, the Ministry of the Environment, Conservation and Parks (MECP) identified that three communities hold or claim Aboriginal or treaty rights that may be adversely impacted by the Greenstone Project (Aroland First Nation, Ginoogaming First Nation and Long Lake #58 First Nation), and that it was delegating aspects of consultation to GGM. MECP also indicated that in addition to GGM’s consultation obligations and delegation of procedural aspects with the Indigenous communities identified above, MECP also requires engagement with people or groups who may have an interest in the Greenstone Project. These communities included: • Animbiigoo Zaagi'igan Anishinaabek • Biigtigong Nishnaabeg; • Biinjitiwaabik Zaaging Anishinaabek; • Bingwi Neyaashi Anishinaabek; • Constance Lake First Nation; • Eabametoong First Nation; • Greenstone Métis Council; • Marten Falls First Nation; • Pays Plat First Nation; • Red Sky Métis First Nation.

Annual Information Form - 119 - Economic Analysis The base case economic model has been developed using a long-term gold price assumption of USD 1,400/oz and an exchange rate of CAD/USD 1.30. Gold production over the LOM is 5,051 koz based on an average processing recovery of 91.2%. Gold production begins during the pre-production period and is treated as revenue partially offsetting pre- production costs. The economic model excludes any project or equipment financing assumptions. The Greenstone Project funding is assumed to be through equity for the purposes of the Greenstone Technical Report. The economic results are calculated as of the start of the pre-production CAPEX phase at Year 3 which includes the remaining detailed engineering and all procurement. The Partnership is not subject to income taxes and each respective joint venture partner will bear the responsibility for paying tax on profits generated by the Partnership. The post-tax results in the Greenstone Technical Report are based on the assumption that GGM is a taxable Canadian entity and tax is calculated based on the tax rules in Ontario. The calculations include tax losses incurred by GGM since the inception of the partnership, but do not reflect the benefit of any historical tax positions held by either joint venture partner (if any). The before-tax project cash flow over the Greenstone Project life is estimated at CAD 3,911M. The Greenstone Project before-tax net present value (NPV) at a discount rate of 5% is estimated to be CAD 2,054M with a before-tax internal rate of return (IRR) of 24.7%. The total after-tax cash flow over the Greenstone Project life is estimated to be CAD 2,716M. The after-tax NPV at a discount rate of 5% is estimated to be CAD 1,364M. The after-tax cash flow results in a 3.2-year payback period from the commencement of commercial operations with an after-tax IRR of 20.1%. Table 5 is a summary of the Greenstone Project economics.

The Greenstone Project is most sensitive to gold price followed by exchange rate, initial capital costs and operating costs. The Greenstone Project is somewhat less sensitive to the CAD/USD exchange rate than the gold price in USD/oz as some of the CAPEX are in US dollars. The sensitivity on gold grade is identical to that of the gold price and is therefore not presented in the following figures.

Project Development In October 2021 the Company announced groundbreaking for full-scale construction of Greenstone with a construction budget of $1.255 million (100% basis) (at a rate of USD:CAD 1.25). Construction is being funded on a pro rata basis with Equinox Gold funding 60% and Orion funding 40%. At December 31, 2023, $1,210 million (99%) of the $1.225 million construction budget had been spent (100% basis). Construction of the process plant was effectively complete and initial commissioning had commenced. All other site facilities, including the TSF, had been completed and handed over to the operations team by year end. Commissioning activities are expected to continue through Q1 2024. Plant operational readiness activities are progressing well, with hot commissioning of the crushing and ore storage dome complete, and wet commissioning of the mills advancing, in anticipation of the first gold pour in Q2, 2024. Production Greenstone’s 2024 production guidance is 105,000 to 125,000 ounces of gold, with cash costs of $690 to $790 per ounce and AISC of $840 to $940 per ounce. 2024 Guidance for Greenstone reflects the Company’s 60% ownership of the project and includes all ounces expected to be produced during the pre-commercial production and commercial production periods. 2024 cash costs per ounce and AISC per ounce guidance figures are the expected costs of gold production after commercial production is achieved.

The directors of Equinox Gold are elected at each annual general meeting to hold office until the next annual general meeting or until their successors are elected or appointed. As of the date of this AIF, six of the Board’s eight directors are independent. Independence is in part a legal and regulatory construct. It is formally assessed annually and considered continually throughout the year to ensure the directors can act objectively and in an unfettered manner, independent of management and free from any interest and any business or other relationship which could, or could reasonably be perceived to, materially interfere with their ability to act in the Company’s best interests. Fraz Siddiqui is “not independent” because he is the Board appointee of Mubadala, an insider of Equinox Gold. Greg Smith is “not independent” because he is the CEO and President of Equinox Gold. The Board has established three committees: the Audit Committee, the Compensation and Nomination Committee and the Environment, Social and Governance Committee. A copy of the Audit Committee Charter, which prescribes the duties and obligations of the Audit Committee, is annexed as Appendix “A” to this AIF. The composition of the Company’s committees as at the date of this AIF is set out in the following table. Board Committee Committee Members Status Audit Committee Lenard Boggio (Chair) Independent Gordon Campbell Independent Marshall Koval Independent Compensation and Nomination Committee Dr. Sally Eyre (Chair) Independent Maryse Bélanger Independent Gordon Campbell Independent Environment, Social and Governance Committee Maryse Bélanger (Chair) Independent Fraz Siddiqui Non-Independent Marshall Koval Independent As at February 21, 2024, the directors and executive officers of Equinox Gold named above as a group exercised control or direction or beneficially owned, directly or indirectly, 27,013,368 Common Shares, equivalent to approximately 8.35% of the issued and outstanding Common Shares. Except as noted below, none of Equinox Gold’s directors or executive officers, or a shareholder holding a sufficient number of securities of Equinox Gold to materially affect the control of the Company: (a) is, as at the date of the AIF, or has been, within 10 years before the date of the AIF, a director, CEO or CFO of any company (including the Company) that:

Annual Information Form - 127 - (i) was subject to, while the director or executive officer was acting in the capacity as director, CEO or CFO of such company, of a cease trade, similar order or an order that denied the relevant company access to any exemption under securities legislation, that was in effect for a period of more than 30 consecutive days (each, an Order); or (ii) was subject to an Order that was issued after the director or executive officer ceased to be a director, CEO or CFO but which resulted from an event that occurred while that person was acting in the capacity as director, CEO or CFO of such company; or (b) is, as at the date of this AIF, or has been within 10 years before the date of the AIF, a director or executive officer of any company (including the Company) that, while that person was acting in that capacity, or within a year of that person ceasing to act in that capacity, became bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency or was subject to or instituted any proceedings, arrangement or compromise with creditors or had a receiver, receiver manager or trustee appointed to hold its assets; or (c) has, within the 10 years before the date of this AIF, become bankrupt, made a proposal under any legislation relating to bankruptcy or insolvency, or become subject to or instituted any proceedings, arrangement or compromise with creditors, or had a receiver, receiver manager or trustee appointed to hold the assets of the director, executive officer of the shareholder; or (d) has been subject to any penalties or sanctions imposed by a court relating to securities legislation or by a securities regulatory authority or has entered into a settlement agreement with a securities regulatory authority; or (e) has been subject to any penalties or sanctions imposed by a court or regulatory body that would likely be considered important to a reasonable investor in deciding whether to make an investment decision. Ms. Bélanger was a director of Mirabela Nickel Limited (MBN) from July 2014 to June 2016. On September 24, 2015, the board of directors of MBN elected to place the company into voluntary administration under the relevant provisions of the Australian Corporations Act 2001. Mr. Boggio was a director of Great Western Minerals Group Ltd. (GWMG) from January 2013 until his resignation together with all the then current directors in July 2015. On April 30, 2015, GWMG announced that a support agreement was entered into with the holders of a majority of GWMG’s secured convertible bonds and GWMG was granted protection from its creditors under the Companies Creditors Arrangements Act on receiving an initial order from the Court. On May 11, 2015, an order was issued by the Financial and Consumers Affairs Authority of the Province of Saskatchewan that all trading in the securities of GWMG be ceased due to its failure to file financial statements for the year ended December 31, 2014. In December 2015, GWMG entered bankruptcy proceedings. Ms. Bélanger and Mr. Boggio were both directors of Pure Gold Mining Inc. (Pure Gold) until March 30, 2023. Pure Gold owned the Madsen Mining property, located near Red Lake Ontario. After redeveloping the property and processing facilities, Pure Gold experienced significant start up and operational difficulties. Consequently, on October 31, 2022, Pure Gold applied for and received an initial order for creditor protection from the Supreme Court of British Columbia (Court) under the Companies’ Creditors Arrangement Act (CCAA). KSV Restructuring Inc. was appointed as the monitor. On November 10, 2022, the Court approved a Sales and Investment Solicitation Process Order, among other relief. On March 30, 2023, the Court approved Pure Gold’s appointment of a Chief Administrative Officer and all members of the Pure Gold board of directors resigned immediately. Pure Gold’s common shares were suspended from trading on the NEX Board of the TSX Venture Exchange. Pure Gold was subsequently acquired by West Lake Gold Mines on June 16, 2023 under the CCAA proceedings.

Annual Information Form - 130 - Conflicts of Interest Certain of the directors and/or officers of Equinox Gold also serve as directors and/or officers of other companies involved in natural resource exploration, development and mining operations and consequently there exists the possibility for such individuals to be in a position of conflict. In particular, Fraz Siddiqui is an employee of Mubadala which is a lender to and has a material relationship with Equinox Gold and may have conflicting interests. See Interest of Management and Others in Material Transactions for further information. In addition, Mr. Smith is chair of the board of directors of Sandbox, a private company of which Equinox Gold owns approximately 20.3%. On October 31, 2023, the Company closed a gold purchase and sale arrangement with Sandbox and Regal Partners Royalties A PTY Limited (Regal and together with Sandbox, the Purchasers) (Sandbox Arrangement). Under the Sandbox Arrangement, the Company is required to deliver specified amounts of gold to the Purchasers in return for an upfront payment of $75.0 million received by the Company on October 31, 2023. Any decision made by any of such directors and/or officers will be made in accordance with their duties and obligations to deal fairly and in good faith with a view to the best interests of Equinox Gold and Equinox Gold shareholders. In addition, each director is required to declare and refrain from voting on any matter in which such director may have a conflict of interest in accordance with the procedures set forth in the BCBCA and other applicable laws.

Annual Information Form - 131 - RISKS RELATED TO THE BUSINESS Equinox Gold’s business is subject to significant risks. Any of these risks could have an adverse effect on Equinox Gold, its business, results of operations, financial position and prospects, and could cause actual events to differ materially from those described in forward-looking statements relating to Equinox Gold. These risks are in addition to those discussed in technical reports and other documents filed by Equinox Gold from time to time on SEDAR+ and on EDGAR. In addition, other risks and uncertainties not presently known by management of Equinox Gold or that management currently believes are immaterial, could affect Equinox Gold, its business and prospects. Funding and Global Economy Risk There is a risk that cash flow from operations will be insufficient to meet current and future obligations and fund development and construction projects, and that additional outside sources of capital will be required. The volatility of global capital markets has generally made the raising of capital by equity or debt financing more difficult. The Company may be dependent upon capital markets to raise additional financing in the future. As such, the Company is subject to liquidity risks in meeting its operating expenditure requirements and future development cost requirements in instances where adequate cash positions are unable to be maintained or appropriate financing is unavailable. The Company seeks to manage its liquidity risk through a rigorous planning, budgeting and forecasting process to help determine the funding requirements to support its current operations, development and expansion plans. However, the factors described above may impact the ability to raise equity or obtain loans and other credit facilities in the future and on terms favourable to the Company. If these levels of volatility persist or if there is an economic slowdown, the Company’s operations, the Company’s ability to raise capital and the trading price of the Company’s securities could be adversely impacted. As the Company’s operations expand and reliance on global supply chains increases, the impact of pandemics, significant geopolitical risk and conflict globally may have a sizeable and unpredictable impact on the Company’s business, financial condition, and operations. The COVID-19 pandemic, the Israel-Hamas war, and the ongoing conflict in Ukraine, including the global response to the Ukraine conflict as it relates to sanctions, trade embargos and military support, have resulted in significant uncertainty as well as economic and supply chain disruptions. Should another significant pandemic develop, the Israel-Hamas war expand, or the Ukraine conflict continue for an extended period of time or expand beyond Ukraine, or should other geopolitical disputes and conflicts emerge in other regions, this could result in material adverse effects to the Company. Gold Price Risk The profitability of the Company is, in part, related to the market price for gold. A decline in the market price for gold could negatively impact the Company’s future operations. Gold prices are affected by various forces beyond Equinox Gold’s control, including global supply and demand, interest rates, exchange rates, inflation or deflation and the political and economic conditions of major gold producing countries. The price of gold has fluctuated widely in recent years, and future price declines could cause continuous development of, and commercial production from, Equinox Gold’s properties to be uneconomic. Future production from Equinox Gold’s mining properties is dependent on gold prices that are adequate to make these properties economically viable. During 2023, the Company took measures to ensure a minimum gold price for a percentage of its gold production to help manage cash flow variability during the construction period of Greenstone and has entered into the following gold collar contracts:

Annual Information Form - 132 - Delivery Term Average Put Strike Price/oz Average Call Strike Price/oz Oz to Deliver per Month February 2023 – March 2024 $1,900 $2,065 10,644 April 2023 – March 2024 $1,950 $2,250 3,050 January 2024 – June 2024 $1,975 $2,185 2,666 January 2024 – June 2024 $1,981 $2,202 8,666 The contracts provide the Company with more certainty regarding revenue during the construction period of Greenstone. However, there is a risk the Company will not benefit from increases in cash flow on the hedged ounces if the gold price exceeds the upper limit of the collars during the term of the contracts. Production and Cost Estimates Equinox Gold prepares forecasts of future production that are estimates based on interpretation and assumptions, and actual production may be less than estimated. Equinox Gold’s ability to achieve its production forecasts is subject to several risks and uncertainties, including the accuracy of Mineral Reserve and Mineral Resource estimates, the accuracy of assumptions regarding ore grades and recovery rates, ground conditions, physical characteristics of ores, the accuracy of estimated rates and costs of mining and processing, and the receipt and maintenance of permits. Equinox Gold prepares estimates of operating costs and/or capital costs for each operation and project. The Company’s actual costs may vary from estimates and are dependent on several factors, including, but not limited to: • the price of gold and by-product metals; • the exchange rate between the USD, MXN, BRL and CAD; • production levels; • increases in operating costs due to inflationary cost pressures, changes in the cost of fuel, power, materials, and other inputs used in mining operations, changes in costs due to supply chain disruptions, equipment limitations, or government intervention through stimulus spending or additional regulations; • the availability and costs of skilled labour and specialized equipment; • the availability and cost of appropriate processing and refining arrangements and related smelting and refining charges; • royalties; and • the timing and cost of construction and maintenance activities. The Company’s inability to manage costs may impact, among other things, future development decisions, which could materially and adversely affect the Company’s business, financial condition, and results of operations. Uncertainty of Mineral Reserves and Mineral Resources Estimates The Mineral Reserves and Mineral Resources published by Equinox Gold are estimates only and no assurance can be given that the anticipated tonnages and grades will be achieved, that the indicated level of recovery will be realized or that Mineral Reserves could be mined or processed profitably. There are numerous uncertainties inherent in estimating Mineral Reserves and Mineral Resources, including many factors beyond Equinox Gold’s control. Such estimation is a subjective process, and the accuracy of any Mineral Reserve or Mineral Resource estimate is a function of the quantity and quality of available data and of the assumptions made and judgements used in engineering and geological interpretation. Short-term operating factors relating to Mineral Reserves, such as the need for orderly development of the ore bodies or the processing of new or different ore grades, may cause the mining operation to be unprofitable in any accounting period. In addition, there can be no assurance that metal

Annual Information Form - 133 - recoveries in small-scale laboratory tests will be duplicated in larger scale tests under on-site conditions or during production. Fluctuation in commodities prices, results of drilling, metallurgical testing and production and the evaluation of mine plans after the date of any estimate may require revision of such estimates. Any material reductions in estimates of Mineral Reserves and Mineral Resources, or of Equinox Gold’s ability to extract these Mineral Reserves, could have an adverse effect on Equinox Gold and its business, results of operations and financial position. Inferred Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability and have a great amount of uncertainty as to their existence, and great uncertainty as to their economic feasibility to mine. A significant amount of exploration work must be completed to determine if an Inferred Mineral Resource may be upgraded to a higher category. Community Action Communities and non-governmental organizations (NGOs) are increasingly vocal and active with respect to mining activities at or near their communities. Some communities and NGOs may take actions that could have an adverse effect on the Company’s operations and reputation, such as commencing lawsuits and establishing blockades that prevent access to the Company’s operations or restrict the delivery of supplies and personnel. In certain circumstances, such actions could ultimately result in the cessation of mining activities and the revocation of permits and licenses. Mining activities at Los Filos were disrupted in each of 2020, 2021 and 2022 because of community blockades and the Company has had short-term disruptions at some of its Brazil operations in 2022 and 2023. Equinox Gold has initiated various programs to enhance its community engagement processes, maintain industry standard social and environmental practices, and reinforce the Company’s commitment to the safety and health of its workforce and surrounding communities. There is no assurance, however, that its efforts will be successful at mitigating all impacts of community actions on the Company’s operations, and the Company may suffer material negative consequences to its business. Property Commitments The properties held by Equinox Gold may be subject to various land payments, royalties and/or work commitments. Failure by Equinox Gold to meet its payment obligations or otherwise fulfill its commitments under these agreements could result in the loss of related property interests. In Mexico, while mineral rights are administered by the federal government through federally issued mining concessions, surface rights over the land located in the mining concessions may be owned by third parties, including Ejidos or Bienes Comunales (communally held land). The Company has secured the surface rights necessary to operate Los Filos through written agreements with one Ejido and two Bienes Comunales, as well as with individual members of the Ejido. These agreements are the subject of current dialogue between the various parties. If these discussions do not result in mutually acceptable renegotiated terms, particularly with respect to the payments made by the Company to operate on such lands, the Company will re-evaluate the current operation and may elect to suspend operations, indefinitely or until such time as new agreements are in place. With respect to Los Filos, various land access agreements have been entered into with local communities and individuals whose properties include the areas occupying Los Filos mine operations. As described above, these agreements are the subject of current dialogue between the various parties. In addition, pursuant to social collaboration agreements with each of the communities Equinox Gold provides benefits such as improvements to communal infrastructure or spending in educational and social support. The Company occasionally receives additional requests and complaints from the communities relating to such commitments. If the Company is unable to address such additional requests or satisfactorily renegotiate terms, it may result in protests, blockades, or other forms of public expression against Equinox Gold’s activities and may have a negative impact on Equinox Gold’s reputation and operations.

Annual Information Form - 134 - Financial Instrument Risk Exposure The Company is exposed in varying degrees to a variety of financial instrument related risks. The Board approves and monitors the risk management process, which includes the following: Market Risk Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. Market prices comprise three types of risk: commodity price risk; interest rate risk and currency risk. Financial instruments affected by market risk include cash and cash equivalents, accounts receivable, marketable securities, reclamation deposits, accounts payable and accrued liabilities, debt and derivatives. The Company holds investments in marketable securities. The fair values of investments in marketable securities are based on the closing share price of the securities at the reporting date. A 10% increase in the applicable share prices would have resulted in a decrease of $0.8 million in the Company’s other comprehensive loss for the year ended December 31, 2023. A 10% decrease in the applicable share prices would have resulted in an increase of $0.8 million in the Company’s other comprehensive loss. Debt and Liquidity Risk Equinox Gold must generate sufficient internal cash flows and/or be able to utilize available financing sources to finance its growth and sustain capital requirements. If the Company does not realize satisfactory sale prices for the gold doré produced from its gold mining operations, or if there are significant delays to when the Company’s growth projects are completed and/or their capital costs were to be significantly higher than estimated, these events could have an adverse effect on Equinox Gold’s business, results of operations and financial position and the Company could be required to raise significant additional capital through the capital markets and/or incur significant borrowings to meet its capital requirements. These financing requirements could result in dilution to existing Equinox Gold shareholders and could adversely affect the Company’s ability to access the capital markets in the future. The Company has a $700 million revolving credit facility available for general corporate purposes of which it has drawn $534.8 million at December 31, 2023. The revolving credit facility also provides for an uncommitted accordion feature which permits the Company to request an increase in the principal amount of the facility by up to $100 million. In addition, the Company has issued the following convertible notes: $139.7 million due April 2024 convertible at $5.25 per share (2019 Convertible Notes); $139.3 million due March 2025 at $7.80 per share (2020 Convertible Notes), and the 2023 Convertible Notes. The Company’s ability to make scheduled payments on the revolving credit facility and any other indebtedness will depend on its financial condition and operating performance, which are subject to prevailing economic and competitive conditions and to certain financial, business, legislative, regulatory and other factors beyond its control. There is no guarantee that additional funding will be available for the development of projects or to refinance existing corporate and project debt. There may be an inability to complete planned investment on the proposed terms or at all due to delays in obtaining or inability to obtain consent of lenders or to execute intercreditor agreements or obtain required regulatory and exchange approvals. Liquidity risk is the risk that Equinox Gold will not be able to meet its financial obligations as they become due, including, among others, debt repayments, interest payments and contractual commitments. Equinox Gold is also exposed to interest rate risk on variable rate debt. If Equinox Gold’s cash flows and capital resources are insufficient to fund its debt service obligations, Equinox Gold could face substantial liquidity problems and could be forced to reduce or delay investments and capital expenditures or to dispose of material assets or operations, seek additional debt or equity capital or restructure or refinance indebtedness, including indebtedness under its revolving credit facility. Equinox Gold may not be able to implement any such alternative measures on commercially reasonable terms or at all and, even if successful, those alternatives may not allow Equinox Gold to meet its scheduled debt service obligations.

Annual Information Form - 135 - In addition, a breach of debt covenants to third parties, including the financial covenants under the Company’s revolving credit facility or Equinox Gold’s other debt instruments from time to time, could result in an event of default under the applicable indebtedness. Such a default may allow the relevant lenders to impose default interest rates or accelerate the related debt, which may result in the acceleration of any other debt to which a cross acceleration or cross default provision applies. In the event a lender accelerates the repayment of Equinox Gold’s borrowings, Equinox Gold may not have sufficient assets to repay its indebtedness. The revolving credit facility and other debt instruments contain several covenants that impose significant operating and financial restrictions on Equinox Gold and may limit Equinox Gold’s ability to engage in acts that may be in its long-term best interest. In particular, the Company’s revolving credit facility restricts the Company’s ability to dispose of assets, to make dividends or distributions, to incur additional indebtedness, or to grant security interests or encumbrances. As a result of these restrictions, Equinox Gold may be limited in how it conducts its business, may be unable to raise additional debt or equity financing, or may be unable to compete effectively or to take advantage of new business opportunities, all of which may affect Equinox Gold’s ability to grow in accordance with its strategy. Further, Equinox Gold’s maintenance of substantial levels of debt could adversely affect its financial condition and results of operations and could adversely affect its flexibility to take advantage of corporate opportunities. Substantial levels of indebtedness could have important consequences to Equinox Gold, including: • limiting Equinox Gold’s ability to obtain additional financing to fund future working capital, capital expenditures, acquisitions or other general corporate requirements, or requiring Equinox Gold to make non-strategic divestitures; • requiring a substantial portion of Equinox Gold’s cash flows to be dedicated to debt service payments instead of other purposes, thereby reducing the amount of cash flows available for working capital, capital expenditures, acquisitions and other general corporate purposes; • increasing Equinox Gold’s vulnerability to general adverse economic and industry conditions, which could affect the Company’s ability to operate its mines effectively, or at all; • exposing Equinox Gold to the risk of increased interest rates for any borrowings at variable rates of interest; • limiting Equinox Gold’s flexibility in planning for and reacting to changes in the industry in which it competes; • placing Equinox Gold at a disadvantage compared to other, less leveraged competitors; and • increasing Equinox Gold’s cost of borrowing. Share Price Fluctuation Securities markets have experienced a high degree of price and volume volatility, and the market price of securities of many companies have experienced wide fluctuations that have not necessarily been related to the companies’ operating performance, underlying asset values or prospects. There can be no assurance that these kinds of share price fluctuations or lack of liquidity will not occur in the future, and if they do occur, the Company does not know how severe the impact may be on Equinox Gold’s ability to raise additional funds through the issuance of equity or other securities. If Equinox Gold is unable to generate adequate revenues or obtain the financing required to successfully operate its mines and complete its development projects, as envisioned, any investment in Equinox Gold may be materially diminished in value or lost.

Annual Information Form - 136 - Foreign Currency Risk Currency risk is the risk that the fair values or future cash flows of the Company’s financial instruments, in functional currency terms, will fluctuate because of changes in foreign exchange rates. Except for Greenstone which uses the Canadian dollar as its functional currency, the Company’s functional currency is USD. The Company is exposed to currency risk on transactions, investments and balances denominated in currencies other than USD, principally BRL, MXN and CAD expenses. Greenstone is exposed to currency risk on transactions and balances denominated in USD. The following table summarizes the Company’s exposure to currency risk arising from financial assets and financial liabilities, excluding foreign exchange contracts, denominated in foreign currencies: At December 31, 2023 (000’s) BRL MXN CAD USD Financial assets $ 23,043 $ 281 $ 103,038 $ 19,908 Financial liabilities $ (89,042) $ (38,348) $ (12,682) $ (48,284) $ (65,999) $ (38,067) $ 90,356 $ (28,376) At December 31, 2022 (000’s) BRL MXN CAD USD Financial assets $ 14,638 $ 244 $ 119,406 $ 8,776 Financial liabilities $ (68,172) $ (28,365) $ (10,159) $ (24,572) $ (53,534) $ (28,121) $ 109,274 $ (15,796) Based on the above foreign currency denominated financial assets and financial liabilities at December 31, 2023, excluding the effect of foreign exchange contracts, the reasonably possible weakening in foreign currencies against the USD and the USD against CAD at such date, assuming all other variables remained constant, would have resulted in the following increase (decrease) in the Company’s net income during the year ended December 31, 2023: 2023 (000’s) BRL – $ 4,818 MXN – $ 5,558 CAD – $ (6,596) USD – $ 2,302 In accordance with its foreign currency exchange risk management program, the Company uses foreign exchange contracts to manage its exposure to currency risk on expenditures in BRL, MXN and CAD, which are accounted for as derivative financial instruments. At December 31, 2023, a 10%, 20%, and 10% weakening in the BRL, MXN and CAD, respectively, against the USD would have resulted in a decrease of $1.7 million in the fair value of the foreign currency net derivative asset and decrease in the Company's net income during the year ended December 31, 2023. A 10%, 20% and 10% strengthening in the BRL, MXN and CAD, respectively, against the USD would have resulted in an increase of $2.4 million in the fair value of the foreign currency net derivative asset and increase in the Company's net income during the year ended December 31, 2023. The BRL and MXN have experienced frequent and substantial variations in relation to the USD and other foreign currencies during the last decades. Depreciation of the BRL and MXN against the USD could create inflationary pressures in Brazil and Mexico and cause increases in interest rates, which could negatively affect the growth of the Brazilian and Mexican economy as a whole and harm the Company’s financial condition and results of operations. On the other hand, appreciation of the BRL and MXN relative to the USD and other foreign currencies could lead to a deterioration of the Brazilian and Mexican foreign exchange denominated current accounts (net), as well as dampen export-driven growth. Depending on the circumstances, either depreciation or appreciation of the BRL or MXN could have an adverse effect on the relevant country’s economy. Foreign Operations Equinox Gold conducts mining, processing, development, exploration, and other activities through subsidiaries in foreign countries, including the United States, Mexico and Brazil. Mining activities are subject to the risks normally associated with any conduct of business in foreign countries including:

Annual Information Form - 137 - • expropriation, nationalization, and the cancellation, revocation, renegotiation, or forced modification of existing contracts, permits, licenses, approvals, or title, particularly without adequate compensation; • changing political and fiscal regimes, and economic and regulatory instability; • unanticipated adverse changes to laws and policies, including those relating to mineral title, royalties and taxation; • delays or inability to obtain or maintain necessary permits, licenses or approvals; • opposition to mine projects, which include the potential for violence, property damage and frivolous or vexatious claims; • restrictions on foreign investment; • unreliable or undeveloped infrastructure; • labour unrest and scarcity; • difficulty obtaining key equipment and components for equipment; • regulations and restrictions with respect to imports and exports; • high rates of inflation; • extreme fluctuations in currency exchange rates and restrictions on foreign exchange, currencies and repatriation; • inability to obtain fair dispute resolution or judicial determinations because of bias, corruption or abuse of power; • abuse of power of foreign governments who impose, or threaten to impose, fines, penalties or other similar mechanisms, without regard to the rule of law; • difficulties enforcing judgments, particularly judgments obtained in Canada or the United States, with respect to assets located outside of those jurisdictions; • difficulty understanding and complying with the regulatory and legal framework with respect to mineral properties, mines and mining operations, and permitting; • violence and the prevalence of criminal activity, including organized crime, theft and illegal mining; • civil unrest, terrorism and hostage taking; • military repression and increased likelihood of international conflicts or aggression; • restriction on the movements of personnel and supplies as the result of pandemics; and • increased public health concerns. Criminal activity in Mexico, including violence between the drug cartels and authorities and incidents of violent crime, theft, kidnapping for ransom and extortion by organized crime, is an ongoing concern. The Mexican government has had limited effectiveness in addressing such criminal activity, which can give rise to uncertainty. Although Equinox Gold has implemented measures to protect its employees, contractors, property and production facilities from these security risks, there can be no assurance that security incidents will not have an adverse effect on the Company’s operations.

Annual Information Form - 138 - The Company’s mining and development properties in Brazil expose the Company to various socioeconomic conditions as well as to local laws governing the mining industry. The Brazilian government has a history of economic interventionism that can give rise to uncertainty. Changes, if any, in mining or investment policies or shifts in political attitude in the jurisdictions in which the Company operates may adversely affect the Company’s operations or profitability. Operations may be affected in varying degrees by government regulations with respect to, but not limited to, restrictions on production, price controls, export controls, currency remittance, importation of parts and supplies, income and other taxes, expropriation of property, foreign investment, maintenance of claims, environmental legislation, land use, land claims of local people, water use and mine safety. Operations can also be affected by government actions against third parties, such as artisanal miners, which can indirectly impact community perception of large mining companies and increase the risk of blockades and other interruptions to operations. In May 2023, Mexico enacted comprehensive changes to its mining and water laws that contain several ambiguities, including how existing mining and water concessions will be treated. Supplementary regulations to the new laws are being developed but have not yet been released. Like others, the Company is facing uncertainty as a result of these new laws. Uncertainty over whether the United States, Mexican or Brazilian governments will implement changes in policy or regulation may contribute to economic uncertainty. Historically, politics in these regions have affected the performance of the economy and past political crises have affected the confidence of investors and the public, generally resulting in an economic slowdown. Operational Risks Equinox Gold’s principal business is the mining, processing of, and exploration for precious metals. Equinox Gold’s mining operations and processing and related infrastructure facilities are subject to risks normally encountered in the mining and metals industry. Although adequate precautions to minimize risk will be taken, operations are subject to hazards that could have an adverse effect on the business, results of operations and financial position of Equinox Gold. Such risks include, without limitation, actual ore mined varying from estimates of grade or tonnage, metallurgical or other characteristics, environmental hazards, tailings risks, industrial accidents, labour disputes, changes in laws, technical difficulties or failures, late delivery of supplies or equipment, unusual or unexpected geological formations or pressures, cave-ins, pit-wall failures, rock falls, unanticipated ground, grade or water conditions, climate change related events such as flooding and droughts, interruptions in or shortages of electrical power or water, periodic or extended interruptions due to the unavailability of materials and force majeure events. Additionally, Equinox Gold’s operations are subject to seasonal weather conditions. As a result of potentially heavy rainfall, pit access and the ability to mine ore may be lower at certain times of the year and may increase the cost of mining. In addition, a prolonged dry season may result in drought conditions, which may also impact production due to insufficient water for processing. Such risks could result in reduced production, damage to, or destruction of, mineral properties or producing facilities, damage to or loss of life or property, environmental damage, delays in mining or processing, economic losses and possible legal liability. Cybersecurity and Information Systems Targeted attacks on Equinox Gold’s systems (or on systems of third parties that Equinox Gold relies on), failure or non-availability of key information technology (IT) systems or a breach of security measures designed to protect Equinox Gold’s IT systems could result in disruptions to Equinox Gold’s operations, extensive personal injury, property damage or financial or reputational risks. Equinox Gold has implemented and regularly tests controls and

Annual Information Form - 139 - disaster recovery infrastructure for certain IT systems. As the threat landscape is ever-changing, the Company takes continuous mitigation efforts, including risk prioritized controls, to protect against known and emerging threats, adopt tools to provide automated monitoring and alerting, and install backup and recovery systems to ensure the Company’s ability to restore systems and return to normal operations. There is no certainty that Equinox Gold’s efforts will adequately protect the Company’s systems and operations. Construction Risks Construction of Greenstone commenced in late 2021. In addition, the Company is progressing studies and engineering for expansion projects at Castle Mountain, Aurizona and Los Filos. Construction of a project requires substantial expenditures and could have material cost overruns versus budget. The capital expenditures and time required for any expansion project or to develop a new mine are considerable and changes in cost or construction schedules can significantly increase both the time and capital required to expand or build the project. Construction costs and timelines can be impacted by a wide variety of factors, many of which are beyond the control of Equinox Gold. These include, but are not limited to, inflation, weather conditions, ground conditions, availability of appropriate rock and other material required for construction, availability and performance of employees, contractors and suppliers, supply chain constraints, shipping risks and delays, delivery and installation of equipment, design changes, accuracy of construction quantities and cost estimates and social acceptance by communities. Project development schedules are also dependent on obtaining and maintaining governmental approvals and the timeline to obtain such approvals is often beyond the control of Equinox Gold. A delay in start-up of commercial production would increase capital costs and delay generating revenues. Given the inherent risks and uncertainties associated with construction and development of projects, there can be no assurance that a construction or expansion project will continue in accordance with current expectations or at all, that construction or expansion costs will be consistent with the budget, that production will be achieved on schedule, or that the mine will operate as planned. Permitting Equinox Gold’s operating, development and exploration activities are subject to receiving and maintaining licenses, permits and approvals (collectively, permits) from appropriate governmental authorities. Before commencing any operations, development or exploration on any of its properties, Equinox Gold must receive numerous permits. As the timing of receiving permits can vary and is largely out of the Company’s control, Equinox Gold may be unable to obtain on a timely basis or maintain in the future all necessary permits to explore and develop its properties, commence construction or operation of mining facilities and properties or maintain continued operations. Delays may occur in connection with obtaining necessary renewals of permits for Equinox Gold’s existing operations and activities, additional permits for existing or future operations or activities, or additional permits associated with new legislation. It is possible that previously issued permits may become suspended or revoked for a variety of reasons, including through change in government regulation or court action. Equinox Gold can provide no assurance that it will continue to hold or obtain, if required to, all permits necessary to develop or continue operating at any particular site, which could adversely affect its operations. Operation, development and exploration of Equinox Gold’s properties require permits from various governmental authorities in the United States, Canada, Mexico and Brazil, respectively. There can be no assurance that all future permits that Equinox Gold requires will be obtainable or renewable on reasonable terms, or at all. Delays or a failure to obtain required permits, or the expiry, revocation or failure to comply with the terms of any such permits that Equinox Gold has already obtained, would adversely affect its business.

Annual Information Form - 140 - Castle Mountain – Phase 2 Permitting There can be no certainty that all necessary licenses and permits required to carry out development of Phase 2 at Castle Mountain will be obtained as currently projected, or as development plans for the project evolve. The process for permitting applications is often complex and time-consuming, requiring a significant amount of time and other resources. The duration and success of efforts to obtain permits are contingent on many variables outside of the Company’s control. In addition, major permitting authorizations may be subject to appeals or administrative protests, resulting in the potential for litigation that could give rise to administrative reconsiderations or reversals of permitting decisions. Appeals and similar litigation processes can result in lengthy delays, with uncertain outcomes. Such issues could impact the expected development timelines at Castle Mountain and have a material adverse effect on the Company’s business. Climate Change Climate change may exacerbate or create new operational risks for the Company. Governments are moving to introduce climate change legislation and treaties at the international, national, state/province and local levels. Regulations relating to emission levels (such as carbon taxes or cap and trade schemes) and energy efficiency are becoming more stringent. If the current regulatory trend continues, Equinox Gold expects that this may result in increased taxes and/or operating costs. In addition, physical risk of climate change may also have an adverse effect on Equinox Gold’s business and may impact the Company’s operations and financial position. These risks include: sea level rise, extreme weather events, impact on water availability and resource shortages due to delivery disruptions. The Company has performed modelling to identify potential climate change risks specific to the Company’s operations to assist in identifying and mitigating such risks going forward. However, Equinox Gold cannot provide assurance that efforts to mitigate the risks of climate changes at all sites will be effective and that the physical risks of climate change will not have an adverse effect on the Company’s business, results of operations and financial position. In March 2021, a historic rain event caused widespread flooding in the Aurizona region and a freshwater pond on the Aurizona site overflowed. The tailings facility and other infrastructure at the Aurizona site were not affected and remained operational. The Company subsequently received several fines from the local state government for environmental infractions related to turbidity in the local community’s water supply. In addition, public civil actions have been filed against the Company in both Maranhão State and Brazil Federal court that claim various damages because of the rain event. The Company considers the fines and public civil actions to be without merit. Water Availability Water availability is an operational risk for all mine sites. The Company’s sites are situated in a variety of climatic zones, including arid and semi-arid regions, as well as areas with distinct seasonal wet and dry periods. Castle Mountain maintains water rights including two producing wells at Castle Mountain and the mine has sufficient water supply for processing purposes for Phase 1 operations. However, additional sources of ground water are required to expand throughput and gold production as contemplated for the Phase 2 expansion. The Company has done extensive drilling to identify additional water sources for the Phase 2 expansion. Water sources with sufficient supply have been identified and the Company is in the process of applying for permits to extract the water. If Equinox Gold is unable to secure permits to extract the additional water supplies, a shortage of adequate water could prevent or limit the Company’s ability to expand production at Castle Mountain.

Annual Information Form - 141 - Santa Luz is situated in a semi-arid region of Brazil and is dependent on the annual rainy season for replenishment of the supply of water. After Santa Luz’s shutdown in 2014, the previous operator began to pump water from the nearby Itapicurú River, the main drainage system in the area, and store water within the C1 open pit for future use. The Company has converted and expanded an existing TSF (as defined herein) into a water storage facility to increase Santa Luz’s water storage capacity. The water storage facility has been filled and is currently being expanded to provide additional water storage capacity. The water is available for use as process water. This is a mitigation measure should insufficient water be available to pump from the Itapicurú River throughout the operational life of the mine. Aurizona is situated in a tropical region of Brazil and receives significant amounts (over 3,000mm on average) of rainfall during the rainy season. Water is collected during the rainy season for use in the processing plant throughout the dry season. The existing TSF and the Boa Esperança open pit are now the primary sources of water storage for the process plant, which has increased available water storage capacity. In addition, a new TSF was completed at the end of 2023 to receive all future tailings deposition, which will allow the existing TSF to be closed. The new TSF provides additional water storage and water for recycling back to the process plant. RDM is situated in a semi-arid region of Brazil and is dependent on the annual rainy season for replenishment of the supply of water. Prolonged drought conditions in the region can contribute to lower-than-expected water recharge in wells as well as lower-than-expected water accumulation in the water storage facilities. The Company’s ability to obtain and secure alternate supplies of water at a reasonable cost depends on many factors, including: regional supply and demand; political and economic conditions; problems that affect local supply; delivery and transportation of water; and relevant regulatory regimes. Previous operators temporarily suspended RDM operations on an annual basis since the mine’s inception in 2014 due to continued regional drought conditions. In 2017, a water storage facility was built to allow for the capture and storage of rainwater and surface water runoff in a larger catchment area; however, insufficient water capture was realized, and operations continued to be temporarily suspended in 2018 and 2019. Since 2020, there has been sufficient water captured within the water storage facility and the TSF to allow RDM to achieve continued operations through the dry season. While the Company has sufficient water to support current operations, there is no guarantee that the Company can secure an alternate source of water in the event of a future prolonged drought. Uninsurable Risks Equinox Gold is subject to several risks and hazards generally, including adverse environmental conditions, industrial accidents, labour disputes, unusual or unexpected geological conditions, ground or slope failures, mechanical failures, cybersecurity incidents, changes in the regulatory environment and natural phenomena such as inclement weather conditions, floods and earthquakes. Such occurrences could result in damage to mineral properties or production facilities, personal injury or death, environmental damage to Equinox Gold’s current properties and future properties of Equinox Gold or the properties of others, delays in mining, monetary losses and possible legal liability. Equinox Gold maintains insurance to protect against certain risks in such amounts as it considers to be reasonable. However, Equinox Gold cannot provide any assurance that its insurance coverage will be sufficient to cover any resulting loss or liability, or that such insurance will continue to be available at economically feasible premiums or for other reasons. While Equinox Gold evaluates the risks to its business and carries insurance policies to mitigate the risk of loss where economically feasible, not all risks are reasonably insurable and insurance coverages may contain limits, deductibles, exclusions, and endorsements. In particular, insurance against risks such as environmental pollution or other hazards as a result of exploration and production is not generally available on acceptable terms to Equinox Gold or to other companies in the mining industry. Likewise, insurance against losses arising from cybersecurity attacks is not generally available on acceptable terms to Equinox Gold. Losses from such events may have an adverse effect on

Annual Information Form - 142 - Equinox Gold, its business, results of operations and financial position. Equinox Gold may also become subject to liability for pollution or other hazards which may not be insured against, or which Equinox Gold may elect not to insure against because of premium costs or other reasons. Losses from these events may cause Equinox Gold to incur significant costs that could have an adverse effect upon its business, results of operations and financial position. Defects in Land Title Equinox Gold does not have title insurance on its properties, and the Company’s ability to ensure that it has obtained a secure claim to individual mineral properties or mining concessions may be severely constrained. Equinox Gold has not conducted surveys of all of the claims in which it holds direct or indirect interests and, therefore, the precise area and location of such claims may be in doubt. Equinox Gold can provide no assurances that there are no title defects affecting its properties. Accordingly, its mineral properties may be subject to prior unregistered liens, agreements, transfers or claims, including indigenous land claims, and title may be affected by, among other things, undetected defects. In addition, Equinox Gold may be unable to operate its properties as permitted or to enforce its rights with respect to its properties. Environmental Risks, Regulations and Hazards All phases of Equinox Gold’s mining operations are subject to environmental regulation in the jurisdictions in which the Company operates. These regulations mandate, among other things, the maintenance of air and water quality standards and land reclamation. They also set out limitations on the generation, transportation, storage and disposal of solid and hazardous waste. Environmental legislation is evolving in a manner which will likely, in the future, require stricter standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and heightened degree of responsibility for companies and their officers, directors and employees. There is no assurance that future changes in environmental regulation, if any, will not adversely affect the Company’s mining operations. Environmental hazards may exist on the properties that are unknown at present that have been caused by previous or existing owners or operators of the properties. Equinox Gold may become liable for such environmental hazards caused by previous owners or operators of the properties. Failure to comply with applicable laws, regulations and permitting requirements may result in enforcement actions thereunder, including fines and orders issued by regulatory or judicial authorities causing operations to cease or be curtailed, and may include corrective measures requiring capital expenditures, installation of additional equipment or remedial actions. Parties engaged in mining operations or in the exploration or development of mineral properties may be required to compensate those suffering loss or damage by reason of the mining activities and may have civil or criminal fines or penalties imposed for violations of applicable laws or regulations. Previous mining by artisanal miners (Garimpeiros) has occurred and continues today on or near certain of Equinox Gold’s Brazilian properties. Garimpeiros are known to use motor oils, other substances and greases in their mining processes, which can result in environmental damage. While Equinox Gold has taken steps to address the activities of the Garimpeiros and the related environmental impacts, there is no certainty that such activities will be discontinued and Equinox Gold may become liable for such environmental hazards caused by Garimpeiro activity. In April 2022, the Mexican Supreme Court issued a decision ordering the cancellation of two mineral claims previously issued to a mining company on the basis that free, prior and informed consultation with Indigenous peoples was not conducted by the Government before the relevant mineral claims were issued. The Court indicated that the relevant mineral claims may be reissued once the required consultations are complete. The draft decision increases the risk of other communities seeking similar injunctions in the future.

Annual Information Form - 143 - The extraction process for gold and metals can produce tailings, which are the slurry and sand-like materials that are a product of the extraction process. Tailings are stored in engineered facilities (TSFs) that are designed, constructed, operated and closed in conformance with federal and state requirements and standard industry practices. Hazards such as uncontrolled seepage or geotechnical failure of retaining dams around tailings disposal areas, however, may result in environmental pollution and consequent liability. Certain of the Company’s operations use heap leaching to extract gold from crushed ore. Heap leaching involves placing ore on impermeable pads and repeatedly spraying the heaps with a weak cyanide solution to recover gold from the ore. The solution carrying the gold is then collected for gold recovery. Heap leach pads are designed, constructed, and operated in accordance with applicable laws and standard industry practices. Hazards such as seepage or geotechnical failure of a heap leach pad, however, may result in environmental pollution and consequent liability. Equinox Gold’s historical operations have generated chemical and metals depositions in the form of tailing ponds, rock waste dumps, and heap leach pads. The Company’s ability to obtain, maintain and renew permits and approvals and to successfully develop and operate mines may be adversely affected by real or perceived impacts associated with Equinox Gold’s activities or of other mining companies that affect the environment, human health and safety. The water collection, treatment and disposal operations at Equinox Gold’s mines are subject to strict regulation and involve significant environmental risks. If collection or management systems fail, overflow or do not operate properly, untreated water or other contaminants could discharge into nearby properties or into nearby streams and rivers, causing damage to persons or property, or to aquatic life and causing economic damages. Liabilities resulting from damage, regulatory orders or demands, revoking of licenses or permits, or similar, could adversely affect Equinox Gold’s business, results of operations and financial condition due to partial or complete shutdown of operations. Moreover, in the event that Equinox Gold is deemed liable for any damage caused by overflow, Equinox Gold’s losses or consequences of regulatory action might not be covered by insurance policies. Government Regulation The operating, development and exploration activities of Equinox Gold are subject to various laws governing prospecting, development, production, exports, imports, taxes, labor standards and occupational health and safety, mine safety, toxic substances, waste disposal, environmental protection and remediation, protection of endangered and protected species, land use, water use, land claims of local people and other matters. Externally driven regulation changes in the countries in which the Company operates add uncertainties that cannot be accurately predicted. Any future adverse changes in government policies or legislation in the jurisdictions in which the Company operates are outside the Company’s control. Any changes in government policy may result in changes to laws affecting ownership of assets, mining policies, monetary policies, taxation, royalty rates, exchange rates, environmental regulations, labor relations and return of capital. This may affect both Equinox Gold’s ability to undertake operating, development and exploration activities in respect of present and future properties in the manner currently contemplated, as well as its ability to continue to explore, develop and operate those properties in which it has an interest or in respect of which it has obtained exploration and development rights to date. The possibility that future governments may adopt substantially different policies, which might extend to expropriation of assets, cannot be ruled out. In May 2023, Mexico enacted comprehensive changes to its mining and water laws that contain several ambiguities, including how existing mining and water concessions will be treated. Supplementary regulations to the new laws are being developed but have not yet been released. Like others, the Company is facing uncertainty as a result of these new laws.

Annual Information Form - 144 - No assurance can be given that new rules and regulations will not be enacted or that existing rules and regulations will not be interpreted in a manner which could have an adverse effect on Equinox Gold and its business, results of operations and financial position. Amendments to current laws, regulations and permits governing operating, development and exploration activities, or more stringent or different implementation, could have an adverse impact on Equinox Gold, or could require abandonment or delays in the development of new mining properties. Failure to comply with any applicable laws, regulations or permitting requirements may result in enforcement actions against Equinox Gold, including significant fines or orders issued by regulatory or judicial authorities causing process, development or exploration activities to cease or be curtailed or suspended, and may include corrective measures requiring capital expenditures, installation of additional equipment or remedial actions. Counterparty Risk Counterparty risk is the risk to Equinox Gold that a party to a contract will default on its contractual obligations to Equinox Gold. Equinox Gold is exposed to various counterparty risks including, but not limited to: (i) financial institutions that hold Equinox Gold’s cash and short-term investments; (ii) companies that have payables to Equinox Gold; (iii) providers of its risk management services, such as hedging arrangements; (iv) shipping service providers that move Equinox Gold’s material; (v) Equinox Gold’s insurance providers; and (vi) Equinox Gold’s lenders. Although Equinox Gold makes efforts to limit its counterparty risk, Equinox Gold cannot effectively operate its business without relying, to a certain extent, on the performance of third-party service providers. Taxation Risk Equinox Gold is subject to taxes, duties, levies, government royalties and other government-imposed compliance costs in several jurisdictions. New taxes or increases to the rates of taxation could have an adverse impact on the results of operations or the Company’s finances. The Company has organized its operations in part based on its understanding and assumptions in relation to various tax laws (including capital gains, withholding tax and transfer pricing) within the jurisdictions in which the Company operates. The Company believes that its understanding and assumptions are reasonable. However, the Company cannot provide assurance that foreign taxation or other authorities will reach the same conclusion. The results of an audit of prior tax filings may have a material impact on Equinox Gold. Equinox Gold is currently appealing federal and municipal value-added tax assessments in Brazil and Mexico. While Equinox Gold is confident that long-term regular recovery of value-added taxes or other amounts receivable from various governmental and nongovernmental counter parties will be established, Equinox Gold cannot guarantee that such taxes will be recovered or that its activities will result in profitable processing operations. On November 3, 2022, the Department of Finance (Canada) released draft legislative proposals in relation to draft legislation released on February 4, 2022, to implement certain tax proposals that are intended to limit the deductibility of certain interest and financing expenses (EIFEL Rules). These proposals, effective for taxation years beginning on or after October 1, 2023, will limit the amount of net interest and financing expenses that may be deducted by certain taxpayers in computing their income to no more than a fixed ratio of tax to EBITDA. The EIFEL Rules are contained in draft legislation which, at the date of this AIF, is progressing through the legislative process. If enacted, the proposals may create an additional tax burden that could impact the cashflow of the Company and may have an adverse impact on the Company and its investors. The Organization for Economic Co-operation and Development (OECD) and the G20 Inclusive Framework on Base Erosion and Profit Shifting have worked on “Global Anti-Base Erosion Model Rules” (GloBE Rules or Pillar Two model rules), that apply to large multinational enterprises (MNE), such as Equinox Gold. The GloBE Rules introduce new taxing mechanisms under which an MNE must pay a top-up tax in any jurisdiction where the effective tax rate is

Annual Information Form - 145 - below the 15% minimum rate. The GloBE Rules framework has been developed by the OECD and, accordingly, will need to be implemented through national legislation in jurisdictions that adopt the rules. If enacted, these rules will impose additional disclosure requirements and may impose an additional tax burden on the Company. Joint Ventures The Company holds a 60% interest in Greenstone through a limited partnership with Orion Mine Finance Group, which holds the remaining 40% interest. As such, the development and operation of Greenstone is subject to the risks normally associated with the conduct of joint ventures which may include (i) disagreements between joint venture partners on how to develop and operate mines efficiently; (ii) that joint venture partners may at any time have economic or business interests or goals that are, or become, inconsistent with another joint venture partner’s business interests or goals; (iii) an inability of joint venture partners to meet their obligations to the joint venture or third parties; (iv) the potential bankruptcy of a joint venture partner; (v) the possibility that a joint venture partner may not be able to sell its interest in the joint venture; or (vi) litigation arising between joint venture partners regarding joint venture matters. The existence or occurrence of one or more such events could have a material adverse impact on the Company’s profitability, future cash flows, earnings, results of operations and financial condition. Acquisitions, Business Arrangements or Transactions Equinox Gold will continue to seek new mining and development opportunities in the mining industry as well as business arrangements or transactions. In pursuit of such opportunities, Equinox Gold may fail to select appropriate acquisition targets or negotiate acceptable arrangements, including arrangements to finance acquisitions or integrate the acquired businesses and their workforce into Equinox Gold. Ultimately, any acquisitions would be accompanied by risks, which could include change in commodity prices, difficulty with integration, failure to realize anticipated synergies, significant unknown liabilities, delays in regulatory approvals and exposure to litigation. There is no guarantee that the sources of financing that have been announced will be successful and that additional funding will be available for development of projects or to refinance existing corporate and project debt. There may be an inability to complete the investment on the proposed terms or at all due to delays in obtaining or inability to obtain the consent of lenders or to execute intercreditor agreements or obtain required regulatory and exchange approvals. Any issues that Equinox Gold encounters in connection with an acquisition, business arrangement or transaction could have an adverse effect on its business, results of operations and financial position. Reclamation Estimates, Costs and Obligations Equinox Gold’s operations are subject to reclamation plans that establish its obligations to reclaim properties after mining and processing operations have concluded. While closure costs are estimated using industry standard practices, often using third parties, it is difficult to determine the exact amounts which will be required to complete all land reclamation activities in connection with the properties in which Equinox Gold holds an interest. Reclamation bonds and other forms of financial assurance represent only a portion of the total amount of money that will be spent on reclamation activities over the life of a mine. Accordingly, these obligations represent significant future costs for Equinox Gold, and it may be necessary to revise planned expenditures, operating plans and reclamation concepts and plans to fund reclamation activities. Such increased costs may have an adverse impact on the business, results or operations and financial position of Equinox Gold. There is a potential future liability for cleanup of tailings deposited on the mining license areas by others during previous periods of mining and reprocessing. It is not possible to quantify at this time what the potential liability may be and detailed assessments need to be made to determine future land reclamation costs, if any.

Annual Information Form - 146 - Infrastructure Mining, processing, development and exploration activities depend, to one degree or another, on having adequate infrastructure. Reliable roads, bridges, power sources and water supply are important determinants which affect capital and operating costs. Unusual or infrequent weather phenomena, terrorism, sabotage, government or other interference in the maintenance or provision of such infrastructure could adversely affect Equinox Gold’s business, results of operations and financial position. Generators currently act as back-up for power outages but, despite provision for backup infrastructure, there can be no assurance that challenges or interruptions in infrastructure and resources will not be encountered. Employee and Labour Relations Some of Equinox Gold’s employees and contractors are unionized. Although the Company has reached agreements and places significant emphasis on maintaining positive relationships with the union and employees, there is a risk of labor strikes and work stoppages. Should they occur, some labor strikes and work stoppages have the potential to significantly affect the Company’s operations and thereby adversely impact the Company’s future cash flows, earnings, production, and financial conditions. Further, relations with employees and contractors may be affected by changes in the scheme of labor relations that may be introduced by the relevant governmental authorities in the jurisdictions in which the mining operations are conducted. Changes in such legislation or otherwise in Equinox Gold’s relationships with its employees may result in strikes, lockouts or other work stoppages, any of which could have an adverse effect on the business, results of operations and financial position. Properties Located in Remote Areas Certain of Equinox Gold’s properties are located in remote areas, some of which have severe climates, resulting in technical challenges for conducting exploration, construction and development activities, and mining. Equinox Gold benefits from modern technologies for operating in areas with severe climates. Nevertheless, Equinox Gold may sometimes be unable to overcome problems related to weather and climate at a commercially reasonable cost, which could have an adverse effect on Equinox Gold’s business, results of operations and financial position. The remote location of certain of Equinox Gold’s operations may also result in increased costs and transportation difficulties. Corruption and Bribery Equinox Gold’s operations are governed by, and involve interactions with, many levels of government in numerous countries. Equinox Gold is required to comply with anti-corruption and anti-bribery laws, including but not limited to the Canadian Corruption of Foreign Public Officials Act, the United States Foreign Corrupt Practices Act, the Brazil Clean Company Act and the Mexico Criminal Code and Anti-Corruption in Public Contracts Act. In recent years, there has been a general increase in both the frequency of enforcement and the severity of penalties under such laws, resulting in greater scrutiny and punishment to companies convicted of violating anti-corruption and anti-bribery laws. Furthermore, a company may be found liable for violations by not only its employees, but also by its contractors and third-party agents. Although Equinox Gold has adopted steps to mitigate such risks, including the implementation of training programs, internal monitoring, reviews and audits, and policies to ensure compliance with such laws, such measures may not always be effective in ensuring that Equinox Gold, its employees, contractors or third-party agents will comply strictly with such laws. If Equinox Gold finds itself subject to an enforcement action or is found to be in violation of such laws, this may result in significant penalties, fines and/or sanctions imposed on Equinox Gold resulting in an adverse effect on Equinox Gold’s reputation and business.

Annual Information Form - 147 - Internal Controls Over Financial Reporting Equinox Gold may fail to maintain the adequacy of its internal controls over financial reporting as such standards are modified, supplemented or amended from time to time, and Equinox Gold cannot ensure that it will conclude on an ongoing basis that it has effective internal controls over financial reporting. Equinox Gold’s failure to satisfy the requirements of Canadian and United States legislation on an ongoing, timely basis could result in the loss of investor confidence in the reliability of its financial statements, which in turn could harm Equinox Gold’s business and negatively impact the trading price and market value of its shares or other securities. In addition, any failure to implement required new or improved controls, or difficulties encountered in their implementation, could harm Equinox Gold’s operating results or cause it to fail to meet its reporting obligations. Equinox Gold may fail to maintain the adequacy of its disclosure controls. Disclosure controls and procedures are designed to ensure that the information required to be disclosed by Equinox Gold in reports filed with securities regulatory agencies is recorded, processed, summarized and reported on a timely basis and is accumulated and communicated to Equinox Gold’s management, as appropriate, to allow timely decisions regarding required disclosure. No evaluation can provide complete assurance that Equinox Gold’s financial and disclosure controls will detect or uncover all failures of persons within Equinox Gold to disclose material information otherwise required to be reported. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance with respect to the reliability of financial reporting and financial statement preparation. The effectiveness of Equinox Gold’s controls and procedures could also be limited by simple errors or faulty judgments. If the Company does not maintain adequate financial and management personnel, processes, and controls, it may not be able to accurately report its financial performance on a timely basis, which could cause a decline in the Company’s share price and harm its ability to raise capital. Failure to accurately report the Company’s financial performance on a timely basis could also jeopardize its continued listing on the TSX or NYSE American or any other exchange on which the Company’s common shares may be listed. Public Perception Damage to Equinox Gold’s reputation can be the result of the actual or perceived occurrence of any number of events, and could include negative publicity, whether true or not. Although Equinox Gold places great emphasis on protecting its image and reputation, it does not have control over how it is perceived by others. Reputation loss may lead to increased challenges in developing and maintaining community relations and, decreased investor confidence and act as an impediment to Equinox Gold’s overall ability to advance its projects, thereby having an adverse impact on financial performance, cash flows, growth prospects, and the market value of the Company’s securities. Equinox Gold May Become Subject to Additional Legal Proceedings Equinox Gold is currently subject party to litigation or other proceedings in Canada, Brazil, Mexico and the United States and may, from time to time, become involved in various claims, legal proceedings, regulatory investigations and complaints. Equinox Gold cannot reasonably predict the likelihood or outcome of any actions should they arise. If Equinox Gold is unable to resolve any such disputes favorably, it may have an adverse effect on Equinox Gold’s financial performance, cash flows, and results of operations. To the extent management believes it is probable that a material cash outflow will be incurred to settle the claim, a provision for the estimated settlement amount is recorded. Equinox Gold’s assets and properties may become subject to further liens, agreements, claims, or other charges as a result of such disputes. Any claim by a third party on or related to any of Equinox Gold’s properties, especially where Mineral Reserves have been located, could result in Equinox Gold losing a commercially viable property. Even if a claim is unsuccessful, it may potentially affect Equinox Gold’s operations due to the high costs of defending against the claim. If Equinox Gold loses a material commercially viable property, such a loss could lower its future revenues, or cause Equinox Gold to cease operations.

Annual Information Form - 148 - Equinox Gold could be forced to compensate those suffering loss or damage by reason of its processing, development or exploration activities and could face civil or criminal fines or penalties imposed for violations of applicable laws or regulations. Any such regulatory or judicial action could materially increase Equinox Gold’s operating costs and delay or curtail or otherwise negatively impact Equinox Gold’s activities. Management The success of Equinox Gold will be largely dependent on the performance of its Board and its management team. The loss of the services of these persons could have an adverse effect on Equinox Gold’s business, results of operations, financial position and prospects. There is no assurance Equinox Gold can maintain the services of its Board and management or other qualified personnel required to operate its business. Failure to do so could have an adverse effect on Equinox Gold and its business, results of operations, financial position and its growth prospects. Employee Recruitment and Retention Recruiting and retaining qualified personnel is critical to Equinox Gold’s success. The number of persons skilled in the acquisition, exploration, development and operation of mining properties is limited and competition for such persons is intense. In particular, there is intense competition for engineers, geologists and persons with mining expertise. As Equinox Gold’s business activity grows, it will require additional key financial, administrative, mining, marketing and public relations personnel as well as additional staff at its operations. Although Equinox Gold believes that it will be successful in attracting and retaining qualified personnel, there can be no assurance of such success as competition for such persons with these skill sets increases. If Equinox Gold is not successful in attracting and retaining qualified personnel, the efficiency of the Company’s operations could be impaired, which could have an adverse impact on Equinox Gold’s future cash flows, earnings, results of operations, and financial condition. Competition The mining industry is very competitive, particularly with respect to properties that produce, or are capable of producing, gold and other metals. Mines have limited lives and, as a result, Equinox Gold continually seeks to replace and expand Mineral Reserves through exploration and the acquisition of new properties. In addition, there is a limited supply of desirable mineral lands available in areas where Equinox Gold would consider conducting exploration and/or production activities. As Equinox Gold faces significant and increasing competition from a number of large established companies, some of which have greater financial and technical resources than Equinox Gold, for a limited number of suitable properties and resource acquisition opportunities, Equinox Gold may be unable to acquire such mining properties on terms it considers acceptable. Equinox Gold competes with other mining companies for the recruitment and retention of qualified directors, professional management, employees and contractors. Competition is also intense for the availability of drill rigs, mining equipment, and production equipment. Competition in the mining industry for limited sources of capital could adversely impact the Company’s ability to acquire and develop suitable gold mines, gold developmental projects, gold producing companies, or properties having significant exploration potential. As a result, there can be no assurance that the Company’s acquisition and exploration programs will yield new Mineral Reserves to replace or expand current Mineral Reserves, or that the Company will be able to maintain production levels in the future. Speculative Nature of Mining Exploration and Development The long-term operation and success of Equinox Gold is dependent, in part, on the cost and success of the Company’s exploration and development projects. Mineral exploration and development is highly speculative and involves significant risks. Major expenses are typically required to locate and establish Mineral Reserves.

Annual Information Form - 149 - Development of Equinox Gold’s mineral projects will only commence after obtaining satisfactory exploration results. Few properties that are explored are ultimately developed into producing properties. There is no assurance that Equinox Gold’s exploration and development activities will result in any discoveries of commercial bodies of ore that will be brought into commercial production. The processes of exploration and development also involves risks and hazards, including environmental hazards, industrial accidents, labour disputes, unusual or unexpected geological conditions or acts of nature. These risks and hazards could lead to events or circumstances which could result in the complete loss of a project or could otherwise result in damage or impairment to, or destruction of, mineral properties and future production facilities, environmental damage, delays in exploration and development interruption, and could result in personal injury or death. Public Company Obligations Equinox Gold’s business is subject to evolving corporate governance and public disclosure regulations that have increased both Equinox Gold’s compliance costs and the risk of non-compliance, which could adversely impact the market value of the Company’s Common Shares or other securities. Equinox Gold is subject to changing rules and regulations promulgated by a number of governmental and self- regulated organizations, including the Canadian and United States securities administrators and regulators, the TSX, the NYSE American, and the International Accounting Standards Board. These rules and regulations continue to evolve in scope and complexity creating many new requirements. Equinox Gold’s efforts to comply with such legislation could result in increased general and administration expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. No History of Dividends Equinox Gold has not, since the date of its incorporation, declared or paid any cash dividends on its Common Shares and does not currently have a policy with respect to the payment of dividends. The payment of dividends in the future will depend on Equinox Gold’s financial condition and such other factors as the Board considers appropriate. Significant Shareholders The Company has certain significant shareholders and holders of convertible notes, that have or will have on exercise of such convertible rights the ability to influence the outcome of corporate actions requiring shareholder approval, including the election of directors of Equinox Gold and the approval of certain corporate transactions. Although, each of these significant shareholders is or may be a strategic partner of Equinox Gold, their respective interests may differ from the interests of Equinox Gold or its other shareholders. The concentration of ownership of the shares may also have the effect of dissuading third-party offers or delaying or preventing other possible strategic transactions of Equinox Gold. Conflicts of Interest Certain of the directors and/or officers of Equinox Gold also serve as directors and/or officers of other companies involved in natural resource exploration, development and mining operations and consequently there exists the possibility for such individuals to be in a position of conflict. In particular, Fraz Siddiqui, a director of Equinox Gold, is also an employee of Mubadala which has a material relationship with Equinox Gold. Any decision made by any of such directors and/or officers will be made in accordance with their duties and obligations to deal fairly and in good faith with a view to the best interests of Equinox Gold and Equinox Gold shareholders. In addition, each director is required to declare and refrain from voting on any matter in which such director may have a conflict of interest in accordance with the procedures set forth in the BCBCA and other applicable laws.

Annual Information Form - 150 - LEGAL PROCEEDINGS AND REGULATORY ACTIONS To Equinox Gold’s knowledge, there are no legal proceedings or regulatory actions material to it to which Equinox Gold is a party, or to which Equinox Gold has been a party since incorporation, or of which any property of Equinox Gold is or has been the subject matter of, since the beginning of the financial year ended December 31, 2022, and no such proceedings are known by the Company to be contemplated. There have been no penalties or sanctions imposed against us by a court relating to provincial or territorial securities legislation or by any securities regulatory authority, there have been no penalties or sanctions imposed by a court or regulatory body against the Company and Equinox Gold has not entered into any settlement agreements before a court relating to provincial or territorial securities legislation or with any securities regulatory authority since Equinox Gold’s incorporation. Equinox Gold is a defendant in various lawsuits and legal actions, including for alleged fines, taxes and labour related matters in jurisdictions where it operates. However, none of these matters exceed 10% of the value of the Company’s current assets. Management regularly reviews these lawsuits and legal actions with outside counsel to assess the likelihood that Equinox Gold will incur a material cash outflow to settle the claim. To the extent management believes it is probable that a material cash outflow will be incurred to settle the claim, a provision for the estimated settlement amount is recorded. INTEREST OF MANAGEMENT AND OTHERS IN MATERIAL TRANSACTIONS Other than transactions carried out in the ordinary course of business of Equinox Gold or any of its subsidiaries and except as described elsewhere in this AIF, none of the directors or executive officers of Equinox Gold or a subsidiary at any time during Equinox Gold’s last completed financial year or within the three most recently completed financial years, any person or company who beneficially owns, or who exercises control or direction over (or a combination of both), directly or indirectly, more than 10% of the issued and outstanding Common Shares, nor the associates or affiliates of those persons, has any material interest, direct or indirect, by way of beneficial ownership of securities or otherwise, in any transaction or proposed transaction which has materially affected or would materially affect Equinox Gold. Certain directors and officers of Equinox Gold are also directors, officers or shareholders of other companies that are similarly engaged in the business of acquiring, developing and exploiting natural resource properties. Such associations to other public companies in the resource sector may give rise to conflicts of interest from time to time. As a result, opportunities provided to a director of Equinox Gold may not be made available to Equinox Gold, but rather may be offered to a company with competing interests. The directors and officers of Equinox Gold are required by law to act honestly and in good faith with a view to the best interests of Equinox Gold and to disclose any personal interest which they may have in any project or opportunity of Equinox Gold, and to abstain from voting on such matters. On March 17, 2021, the Company completed the first tranche of a non-brokered private placement (the Private Placement) of subscription receipts at a price of C$10.00 per subscription receipt. The second tranche of the Private Placement was completed on April 7, 2021, in conjunction with the closing of the acquisition of Premier Gold. The total proceeds to the Company from the issuance of the subscription receipts was C$75 million. Certain of the Company’s executives and directors subscribed for C$40.4 million in subscription receipts which is a related party transaction. No finders fees or commissions were paid in connection with the financing. Proceeds of the financing were used for general working capital purposes. On June 28, 2022, the Company completed the sale of a portfolio of royalties and other assets to Sandbox for consideration of $28.4 million common shares of Sandbox, representing a 35% interest in Sandbox. On closing of the transaction Greg Smith, then President of Equinox Gold, was appointed as chief executive officer and a director of Sandbox. Effective September 1, 2022 the Equinox Gold and Sandbox entered into a services agreement under which

Annual Information Form - 151 - Equinox Gold provided certain executive and corporate development services (Services Agreement). The total value of services provided was C$35,007 and the Services Agreement terminated effective November 7, 2022. Mr. Smith resigned from his role as chief executive officer of Sandbox effective November 7, 2022 but remains a director and the Chair of Sandbox. The Company is party to an investor rights agreement (Investor Rights Agreement) dated April 11, 2019, with Mubadala, pursuant to which Mubadala holds certain non-dilution rights that allow it to maintain its pro rata interest in the Company. Effective November 20, 2022, the parties amended the Investor Rights Agreement to provide Mubadala with a biannual top-up right in connection with common shares issued by Company pursuant to any at-the-market distribution. Mubadala’s representative on the Board at the time of the vote, Mr. Francois Bellemare, disclosed his interest and did not vote in respect of the matter. The directors and officers of Equinox Gold are aware of the existence of laws governing the accountability of directors and officers for corporate opportunity and requiring disclosure by the directors of conflicts of interests and Equinox Gold will rely on such laws in respect of any directors’ and officers’ conflicts of interest or in respect of any breaches of duty by any of its directors and officers. MATERIAL CONTRACTS Except for contracts entered into in the ordinary course of business, the Company has not entered into any material contracts during the most recently completed financial year or before the most recently completed financial year (but after January 1, 2002) which are still in force and effect, and which may reasonably be regarded as presently material other than as set out below: • 2023 Convertible Notes dated September 21, 2023. • Third Amended and Restated Credit Agreement dated July 28, 2022, as amended February 17, 2023, March 24, 2023, and October 31, 2023, with the Bank of Nova Scotia as administrative agent, BMO Capital Markets and ING Capital LLC as co-syndication agents and several lenders. • 2019 Convertible Notes and 2020 Convertible Notes dated April 11, 2019, and March 10, 2020 respectively, and as amended and restated on April 7, 2021, December 14, 2021, July 28, 2022 and February 17, 2023. • Equity Distribution Agreement dated November 21, 2022, with BMO Nesbitt Burns Inc., BMO Capital Markets Corp., National Bank Financial Inc., and National Back of Canada Financial Inc.

The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending on where the molten rock solidified. Indicated Mineral Resource* The part of a Mineral Resource for which quantity, grade or quality, densities, shape and physical characteristics are estimated with sufficient confidence to allow the application of Modifying Factors in sufficient detail to support mine planning and evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to assume geological and grade or quality continuity between points of observation. An Indicated Mineral Resource has a lower level of confidence than that applying to a Measured Mineral Resource and may only be converted to a Probable Mineral Reserve.

Annual Information Form - 155 - Term Definition Inferred Mineral Resource* The part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. In-fill The collection of additional samples between existing samples, used to provide greater geological detail and to provide more closely-spaced assay data. intrusive Igneous rock which, while molten, penetrated into or between other rocks and solidified before reaching the surface. life-of-mine (LOM) The plan for how the Company will mine in a particular area and for how long. lode A mineral deposit, consisting of a zone of veins, veinlets or disseminations, in consolidated rock as opposed to a placer deposit. low-grade Descriptive of ores relatively poor in the metal they are mined for; lean ore. mafic A group of dark-colored minerals, composed chiefly of magnesium and iron, that occur in igneous rocks. Measured Mineral Resource* The part of a Mineral Resource for which quantity, grade or quality, densities, shape, and physical characteristics are estimated with confidence sufficient to allow the application of Modifying Factors to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological and grade or quality continuity between points of observation. A Measured Mineral Resource has a higher level of confidence than that applying to either an Indicated Mineral Resource or an Inferred Mineral Resource. It may be converted to a Proven Mineral Reserve or to a Probable Mineral Reserve. metamorphic The process by which the form or structure of rocks is changed by heat and pressure. mill A processing facility where ore is finely ground and then undergoes physical or chemical treatment to extract the valuable metals. Also, the device used to perform grinding (milling). mineral claim/property Authorizes the holder to prospect and mine for minerals and to carry out works in connection with prospecting and mining. Mineral Reserve* The economically mineable part of a Measured and/or Indicated Mineral Resource. It includes diluting materials and allowances for losses, which may occur when the material is mined or extracted and is defined by studies at pre-feasibility or feasibility level as appropriate that include application of Modifying Factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified. Mineral Reserves are sub- divided in order of increasing confidence into Probable Mineral Reserves and Proven Mineral Reserves. A Probable Mineral Reserve has a lower level of confidence than a Proven Mineral Reserve.

Annual Information Form - 156 - Term Definition Mineral Resource* A concentration or occurrence of solid material of economic interest in or on the Earth’s crust in such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction. The location, quantity, grade or quality, continuity and other geological characteristics of a Mineral Resource are known, estimated or interpreted from specific geological evidence and knowledge, including sampling. Mineral Resources are sub- divided, in order of increasing geological confidence, into Inferred, Indicated and Measured categories. An Inferred Mineral Resource has a lower level of confidence than that applied to an Indicated Mineral Resource. An Indicated Mineral Resource has a higher level of confidence than an Inferred Mineral Resource but has a lower level of confidence than a Measured Mineral Resource. muscovite A phyllosilicate mineral of aluminum and potassium. It has a highly-perfect basal cleavage yielding very thin sheets, which are often highly elastic.

Oxidation tends to make the ore more amenable to cyanide solutions so that minute particles of gold will be readily dissolved. preliminary economic assessment (PEA) A study, other than a pre-feasibility study or feasibility study, which includes an economic analysis of the potential viability of Mineral Resources. The PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves and there is no certainty that the PEA based on these Mineral Resources will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. pre-feasibility study A comprehensive study of a range of options for the technical and economic viability of a mineral project that has advanced to a stage where a preferred mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, is established and an effective method of mineral processing is determined. It includes a financial analysis based on reasonable assumptions on the Modifying Factors and the evaluation of any other relevant factors which are sufficient for a Qualified Person, acting reasonably, to determine if all or part of the Mineral Resource may be converted to a Mineral Reserve at the time of reporting. A pre-feasibility study is at a lower confidence level than a feasibility study. Probable Mineral Reserve* The economically mineable part of an Indicated, and in some circumstances, a Measured Mineral Resource. The confidence in the Modifying Factors applying to a Probable Mineral Reserve is lower than that applying to a Proven Mineral Reserve. Proven Mineral Reserve* The economically mineable part of a Measured Mineral Resource. A Proven Mineral Reserve implies a high degree of confidence in the Modifying Factors. pyrite A yellow iron sulphide mineral, normally of little value. It is sometimes referred to as “fool’s gold.”
