Financial Statements
(in United States dollars, unless otherwise stated)
For the years ended December 31, 2024 and 2023

MANAGEMENT’S RESPONSIBILITY FOR FINANCIAL REPORTING
The accompanying consolidated financial statements of Alamos Gold Inc. (the “Company”) and the information in these annual consolidated financial statements are the responsibility of management and have been reviewed and approved by the Company’s board of directors (the “Board of Directors”). The consolidated financial statements have been prepared by management in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. In the preparation of these consolidated financial statements, estimates are sometimes necessary when transactions affecting the current accounting period cannot be finalized with certainty until future periods. Management believes that such estimates, which have been properly reflected in the accompanying consolidated financial statements, are based on the best estimates and judgements of management.
To discharge its responsibilities for financial reporting and safeguarding of assets, management depends on the Company’s systems of internal control over financial reporting. These systems are designed to provide reasonable assurance that the financial records are reliable and form a proper basis for the timely and accurate preparation of the consolidated financial statements. The Chief Executive Officer and Chief Financial Officer have assessed the design, implementation and operating effectiveness of internal control over financial reporting as at December 31, 2024. Based on its assessment, management concluded that, as of December 31, 2024, the Company’s internal control over financial reporting was effective.
The Company acquired Argonaut Gold Inc ("Argonaut") on July 12, 2024. The financial information for this acquisition is included in Note 6 to the consolidated financial statements. The Canadian Securities Administrators’ National Instrument 52-109 ("NI 52-109") and the U.S. Securities and Exchange Commission (the "SEC") staff provide an exemption whereby companies undergoing acquisitions can exclude the acquired business in the year of acquisition from the scope of testing and assessment of design and operational effectiveness of controls over financial reporting. In accordance with NI 52-109 and SEC staff guidance, the Company’s management excluded Argonaut from management’s report on internal control over financial reporting for the year ended December 31, 2024. A summary of the financial information for Argonaut, which was included in the consolidated financial statements of the Company for the year ended at December 31, 2024 from July 12, 2024, is as follows:
•Revenue: $81.2 million;
•Earnings from operations: $6.6 million;
•Total assets: $1.1 billion;
•Total liabilities: $44.6 million.
The Board of Directors oversees management’s responsibilities for the consolidated financial statements primarily through the activities of its Audit Committee, which is composed solely of directors who are neither officers nor employees of the Company. This Committee meets with management and the Company’s independent auditors, KPMG LLP, to ensure that management properly fulfill its financial reporting responsibilities, review the consolidated financial statements, and recommend approval by the Board of Directors. The Audit Committee provides full and unrestricted access to the independent auditors, and also meets with the independent auditors without the presence of management, to discuss the scope and results of their audits, the adequacy of internal control over financial reporting, and the quality of financial reporting.
The consolidated financial statements have been audited by KPMG LLP (Auditor Firm ID: 85), an independent registered public accounting firm, in accordance with the standards of the Public Company Accounting Oversight Board (United States).

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors of Alamos Gold Inc.
Opinion on the Consolidated Financial Statements
We have audited the accompanying consolidated statements of financial position of Alamos Gold Inc. (the Company) as of December 31, 2024 and 2023, the related consolidated statements of comprehensive income, changes in equity, and cash flows for each of the years then ended, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and its financial performance and its cash flows for each of the years then ended, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 19, 2025, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matter
The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Evaluation of the recoverable amount of the Young-Davidson cash generating unit
As discussed in Note 9 to the consolidated financial statements, the carrying value of the Company’s mineral property, plant and equipment balance was $4,618.0 million as of December 31, 2024, of which $1,563.3 million relates to the Young-Davidson CGU. As at September 30, 2024, the Company identified an indication of impairment reversal for the Young-Davidson CGU and the recoverable amount was determined to be greater than the carrying amount which resulted in a reversal of $57.1 million. As discussed in Notes 5 and 9(i) to the consolidated financial statements, the estimated undiscounted cash flows used to assess recoverability of long-lived assets and to measure the fair value of the Company’s mining operations are derived from current life of mine plans and the value of mineral resources outside the life of mine. Key assumptions used in determining the recoverable amount of Young-Davidson included estimated 2025-2027 and long-term gold price of $2,120 - $2,300 and $1,950 per ounce, respectively; 2025 – 2027 and long-term foreign exchange rate for $1 United States dollar of $1.35 Canadian dollar and $1.33 Canadian dollar, respectively; and discount rate of 5%. Assumptions also include estimates of input costs, timing and cost to develop and produce proven and probable mineral reserve estimates.

We identified the evaluation of the recoverable amount of the Young-Davidson CGU as a critical audit matter. Significant auditor judgment was required to assess the significant assumptions of future operating and capital costs, production levels, future gold prices, future foreign exchange rates, the discount rate and the value of mineral resources outside the life of mine. In addition, auditor judgment was required to evaluate the mineral reserves and resources which form the basis of the recoverable amount.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s process to determine the recoverable amount of the CGU, determination of future cash flows in the life of mine model used to estimate the recoverable amount of the cash generating unit and the development of the significant assumptions. We assessed the competence, capabilities and objectivity of the Company’s personnel who prepared the mineral reserves and resources information, including the industry and regulatory standards they applied. We evaluated the Company’s future operating and capital costs and production levels used in the life of mine plan by comparing them to historical results. We involved valuation professionals with specialized skills and knowledge who assisted in:
•evaluating the estimated future gold prices and the future foreign exchange rates by comparing them to third party estimates
•evaluating the discount rate by comparing to an estimate that was independently developed using publicly available information and data for comparable entities
•assessing the value of mineral resources outside the life of mine by comparing the assumption to the implied value per ounce from comparable market transactions and the implied value per ounce of the mineral reserves and resources in the discounted cash flow model
Acquisition of Argonaut Gold Inc. - valuation of mineral properties
As discussed in Note 6 to the consolidated financial statements, the Company completed the acquisition of Argonaut Gold Inc. (“Argonaut”) on July 12, 2024 for consideration of $419.0 million. Based on the provisional allocation of the purchase price, the Company recorded $307.3 million of mineral properties. As discussed in Note 5 to the consolidated financial statements, the measurement of the provisional fair values as at the acquisition date requires the Company to make certain judgments and estimates including estimates of mineral reserves and mineral resources of the assets acquired, future production levels, future operating costs, capital expenditures, discount rates, future metal prices, long term foreign exchange rates and value of resources outside of life of mine plan.
We identified the evaluation of the provisional fair value of the mineral properties acquired in the acquisition of Argonaut as a critical audit matter. Significant auditor judgment was required to evaluate key assumptions of future production levels, future metal prices, long-term foreign exchange rates, future operating costs and capital expenditures, the discount rate and the value of resources outside of life of mine plan. In addition, auditor judgment was required to evaluate the mineral reserves and resources which form the basis of the provisional fair value of the mineral properties.
The following are the primary procedures we performed to address this critical audit matter. We evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s process to determine the provisional fair value of the acquired mineral properties, including future cash flows in the life of mine plan used and the development of significant assumptions. We assessed the competence, capabilities and objectivity of the Company’s personnel who prepared the mineral reserves and resources information, including the industry and regulatory standards they applied. We evaluated the Company’s future operating and capital costs and production levels used in the discounted cash flow model by comparing them to third party technical reports, actual historical results and the Company’s other mines in Ontario. We involved valuation professionals with specialized skills and knowledge who assisted in:
•evaluating the estimated future gold prices and the future foreign exchange rates by comparing them to third party estimates
•evaluating the discount rate by comparing to an estimate that was independently developed using publicly available information and data for comparable entities
•assessing the value of resources outside of life of mine, by comparing the assumption to the implied value per ounce from comparable market transactions.

Report of Independent Registered Public Accounting Firm
To the Shareholders and Board of Directors of Alamos Gold Inc.
Opinion on Internal Control Over Financial Reporting
We have audited Alamos Gold Inc.’s (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of financial position of the Company as of December 31, 2024 and 2023, the related consolidated statements of comprehensive income, changes in equity and cash flows for each of the years in the two-year period ended December 31, 2024, and the related notes (collectively, the consolidated financial statements), and our report dated February 19, 2025 expressed an unqualified opinion on those consolidated financial statements.
The Company acquired Argonaut Gold Inc. during 2024, and management excluded from its assessment of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2024, Argonaut Gold Inc.’s internal control over financial reporting associated with total assets of $1.1 billion and total revenues of $81.2 million included in the consolidated financial statements of the Company as of and for the year ended December 31, 2024. Our audit of internal control over financial reporting of the Company also excluded an evaluation of the internal control over financial reporting of Argonaut Gold Inc.
Basis for Opinion
The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, appearing under the heading Internal Control over Financial Reporting in Management’s Discussion and Analysis for the year ended December 31, 2024. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
Definition and Limitations of Internal Control Over Financial Reporting
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

ALAMOS GOLD INC.
Notes to Consolidated Financial Statements
December 31, 2024 and 2023
(In United States dollars, unless otherwise indicated, tables stated in millions of United States dollars)

1 | DESCRIPTION OF BUSINESS AND NATURE OF OPERATIONS

Alamos Gold Inc. ("Alamos"), a company incorporated under the Business Corporation Act (Ontario), and its wholly-owned subsidiaries (collectively the “Company”) is a publicly traded company with common shares listed on the Toronto Stock Exchange (TSX:AGI) and the New York Stock Exchange (NYSE: AGI). The Company's registered office is located at 181 Bay Street, Suite 3910, Toronto, Ontario, M5J 2T3.
Alamos is a Canadian-based intermediate gold producer with diversified production from three operations in North America. This includes the Island Gold District (comprising the Island Gold and Magino mines) and Young-Davidson mine in Northern Ontario, Canada and the Mulatos District in Sonora State, Mexico. Additionally, the Company has a portfolio of growth projects, including the Phase 3+ Expansion at Island Gold, the Lynn Lake project in Manitoba, Canada and the Puerto Del Aire project in the Mulatos District.

2 | BASIS OF PREPARATION

These consolidated financial statements are prepared in accordance with International Financial Reporting Standards (“IFRS”) as issued by the International Accounting Standards Board (“IASB”) effective as of December 31, 2024. IFRS comprises IFRSs, International Accounting Standards ("IASs"), and interpretations issued by the IFRS Interpretations Committee ("IFRICs").
These consolidated financial statements have been prepared using the historical cost convention, other than those assets and liabilities that are measured at revalued amounts or fair values at the end of each reporting period and which are measured in accordance with the policies disclosed in Note 3.
The consolidated financial statements were authorized for issue by the Board of Directors on February 19, 2025.

3 | SUMMARY OF MATERIAL ACCOUNTING POLICIES

(a) Basis of consolidation
These consolidated financial statements include the accounts of the Company and its subsidiaries. Subsidiaries are entities controlled by the Company. All subsidiaries are wholly-owned. Control exists when the Company is exposed, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Subsidiaries are included in the consolidated financial results of the Company from the effective date of acquisition up to the effective date of disposition or loss of control. The Company's principal properties and material subsidiaries of the Company and their geographic locations at December 31, 2024 were as follows:

Direct parent company |  | Country of incorporation | Mining properties and projects owned
Alamos Gold Inc |  | Canada | Island Gold Mine Young-Davidson Mine Lynn Lake project
Argonaut Gold Inc. |  | Canada | Magino Mine
Minas de Oro Nacional, S.A. de C.V. |  | Mexico | The Mulatos District
Dogu Biga Madencilik Sanayi Ticaret AS |  | Türkiye | Turkish properties

All intra-group transactions, balances, income and expenses are eliminated in full upon consolidation.
(b) Foreign currency
These consolidated financial statements are presented in United States dollars (“US dollars”), which is the functional currency of the Company and all of its subsidiaries.
Transactions in currencies other than the Company's or a subsidiary's functional currency (“foreign currencies”) are recognized at the rates of exchange prevailing at the dates of the transactions. At the end of each reporting period, monetary assets and liabilities denominated in foreign currencies are translated at the rates prevailing at that date. Foreign currency non-monetary items that are measured in terms of historical cost are not retranslated.

10 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

Exchange differences are recognized in net earnings in the period in which they arise. Exchange differences on foreign deferred tax assets and liabilities are presented as deferred income tax expense on the Consolidated Statements of Comprehensive Income.
(c) Cash and cash equivalents
The Company considers deposits in banks, certificates of deposits, and short-term investments with original maturities of three months or less from the acquisition date as cash and cash equivalents.
(d) Inventories
Parts and supplies inventory
Supplies inventory consists of mining supplies and consumables used in the operation of the mines, and is valued at the lower of average cost and net realizable value. Provisions are recorded to reflect present intentions for the use of slow moving and obsolete parts and supplies inventory.
Stockpile inventory
Stockpiles represent ore that has been mined and is available for further processing. Stockpiles are measured by estimating the number of tonnes added and removed from the stockpile. Stockpile ore tonnages are verified by periodic surveys. Costs are allocated to stockpiles based on the current mining cost per tonne incurred up to the point of stockpiling the ore, including applicable overhead, depletion and amortization relating to mining operations, to the extent determined recoverable, and are removed at the average cost per tonne. Stockpile inventory is measured at the lower of cost and net realizable value. Stockpiled ore that is expected to take longer than 12 months to recover is presented as a non-current asset.
In-process inventory
The recovery of gold is achieved through milling and heap leaching processes. Costs are added to ore on leach pads and in the mill based on the current stockpiled mining cost and current processing cost, including applicable overhead, depletion and amortization relating to processing operations. Costs are removed from ore on leach pads and in the mill as ounces are recovered, based on the average cost per recoverable ounce of gold in-process inventory. In-process inventory is measured at the lower of cost and net realizable value.
Finished goods inventory
Finished goods inventory consists of dore bars containing predominantly gold by value which are generally refined off-site to return saleable metals. Dore inventory is valued at the lower of weighted average cost and net realizable value.
For all classes of gold inventory, net realizable value is calculated as the difference between the estimated future metal revenue based on prevailing and/or long-term metal prices as appropriate, and estimated costs to complete production into a saleable form.
(e) Long-lived assets
Mineral property, plant and equipment
Mineral property, plant and equipment is recorded at cost less accumulated amortization and accumulated impairment losses. The initial cost of an asset is comprised of its purchase price or construction cost, any costs directly attributable to bringing the asset into operation, and the initial estimate of any reclamation obligation. The purchase price is the fair value of consideration given to acquire the asset. The value of right-of-use ("ROU") assets are also included within property, plant and equipment. Subsequent costs are included in the asset’s carrying amount when it is probable that future economic benefits associated with the asset will flow to the Company, and the costs can be measured reliably. This would include costs related to the refurbishment or replacement of major components of an asset, when the refurbishment results in a significant extension in the physical life of the component. All other repairs and maintenance costs are recognized in net earnings as incurred.
The cost of property, plant and equipment, less any applicable residual value, is allocated over the estimated useful life of the asset on a straight-line basis, or on a unit-of-production basis if that method is more reflective of the allocation of benefits among periods. Amortization commences on an asset when it has been fully commissioned and is available for use.

11 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

Amortization rates applicable to each category of property, plant and equipment, with the exception of land, are as follows:

Asset | Useful life
Leasehold improvements | Lease term
Mobile equipment | 2-10 years
Other equipment | 2-20 years
Processing plant | Unit-of-production
Shaft, underground infrastructure and mineral properties | Unit-of-production
Lease ROU assets | 2-5 years
Vehicles | 3-7 years
Buildings | 7-20 years
Office equipment | 2-8 years

When components of an item of property, plant and equipment have different useful lives than those noted above, they are accounted for as separate items of property, plant and equipment. Each asset or component’s estimated useful life is determined considering its physical life limitations; however, this physical life cannot exceed the remaining life of the mine at which the asset is utilized. Estimates of remaining useful lives and residual values are reviewed annually and when events and circumstances indicate that such a review should be made. Any changes in estimates of useful lives are accounted for prospectively from the date of the change.
Exploration and evaluation expenditures
Expenditures incurred prior to the Company obtaining the right to explore are expensed in the period in which they are incurred.
Exploration and evaluation expenditures include costs such as exploratory drilling, sample testing, and costs of pre-feasibility and other technical studies. Exploratory drilling and other exploration costs incurred on sites without an existing mine and on areas outside the boundary of a known mineral deposit which contain proven and probable reserves and resources of which there is sufficient geologic certainty of converting a mineral deposit into a proven and probable reserve, are expensed. Evaluation expenditures related to activities located within the boundary of a known mineral deposit as described above are capitalized and included in the carrying amount of the related mining property. Management uses the following criteria in its assessment of the boundary of the known mineral deposit: (i) geology: there is sufficient geologic certainty of converting a mineral deposit into a proven and probable reserve. There is a history of conversion to reserves at operating mines; (ii) scoping, pre-feasibility or feasibility: there is a scoping study, pre-feasibility or preliminary feasibility study that demonstrates the additional reserves and resources will generate a positive commercial outcome. Known metallurgy provides a basis for concluding there is a significant likelihood of being able to recover the incremental costs of extraction and production; (iii) accessible facilities: the mineral deposit can be processed economically at accessible mining and processing facilities where applicable; (iv) life of mine plans: an overall life of mine plan and economic model to support the economic extraction of reserves and resources exists. A long-term life of mine plan and supporting geological model identifies the drilling and related development work required to expand or further define the existing ore body; and (v) authorizations: operating permits and feasible environmental programs exist or are obtainable. All capitalized exploration and evaluation assets are monitored for indications of impairment, to ensure that exploration activities related to the property are continuing and/or planned for the future. If an exploration property does not prove viable, an impairment loss is recognized in net earnings as the excess of the carrying amount over the recoverable amount (refer to Note 3(f) for definition of recoverable amount) in the period in which that determination is made.
Capitalized exploration and evaluation assets are subsequently reclassified to mine development costs upon determining that the technical feasibility and commercial viability of extracting a mineral resource are demonstrable and the Board of Directors has approved project advancement. The Company performs an impairment test, based on the recoverable amount, prior to the reclassification of exploration and evaluation assets to mine development costs.
Mining interests and mine development costs
The Company may hold interests in mineral properties in various forms, including prospecting licenses, exploration and exploitation concessions, mineral leases and surface rights. The Company capitalizes payments made in the process of acquiring legal title to these properties.
Property acquisition and mine development costs are recorded at cost. Mine development costs incurred to expand operating capacity, develop new ore bodies or develop mine areas in advance of current production are capitalized. Mine development costs related to current period production are recorded in inventory. Borrowing costs for qualifying assets are capitalized to mine development costs while construction and development activities at the property are in progress. Items may be produced while bringing an item of property, plant and equipment to the location and condition necessary for it to be capable of operating in the manner intended by management (such as samples produced when testing whether the asset is functioning properly). An entity recognizes the proceeds from selling any such items, and the cost of those items, in profit or loss in accordance with applicable Standards.

12 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

Subsequent to the commencement of commercial production, further development expenditures incurred with respect to a mining interest are capitalized as part of the mining interest, when it is probable that additional future economic benefits associated with the expenditure will flow to the Company. Otherwise, such expenditures are classified as mining and processing costs.
Once the asset is capable of operating as management has intended, mining interests are depleted over the life of the mine using the unit-of-production method based on estimated proven and probable mineral reserves of the mine and the portion of mineralization from measured, indicated and inferred mineral resources expected to be classified as mineral reserves, in applicable mines. The Company determines the portion of mineralization expected to be classified as mineral reserves by considering the degree of confidence in the economic extraction of the resource, which is affected by long-term metal price assumptions, cut-off grade assumptions, and drilling results. These assessments are made on a mine-by-mine basis.
The expected reserves used in depletion calculations are determined based on the facts and circumstances associated with the mining interest. Any changes in estimates of reserves are accounted for prospectively from the date of the change.
Capitalized stripping costs
Pre-production stripping costs are capitalized as part of the cost of constructing a mine.
Mining costs associated with stripping activities during the production phase of a mine are capitalized only if the Company can identify the component of the ore body for which access is obtained, the costs associated with the related stripping activities can be measured reliably, and the activities represent a future benefit to the mining interest, in that access is gained to sources of mineral reserves and resources that will be produced in future periods that would otherwise not have been accessible. Production stripping costs are allocated between inventory and capital based on the expected volume of waste extracted for a given volume of ore production. The expected volume of waste to be allocated to inventory is determined with reference to the life of mine stripping ratio of a particular mine or deposit, with the remaining amount allocated to capital. The amount of waste capitalized is calculated by multiplying the stripping tonnes mined during the period by the current mining cost per tonne in the open pit.
Capitalized stripping costs are depleted over the expected mineral reserves and resources benefiting from the stripping activity using the unit-of-production method based on estimated proven and probable mineral reserves, and the portion of mineralization expected to be classified as mineral reserves.
Investment tax credits
Investment tax credits are earned as a result of incurring eligible exploration and development expenses prior to commercial production. Investment tax credits are accounted for as a reduction to property, plant and equipment or mining interests.
Investment tax credits also arise as a result of incurring eligible research and development expenses and these credits are recorded as a reduction to the related expenses.
Derecognition
Upon replacement of a major component, or upon disposal or abandonment of a long-lived asset, the carrying amounts of the assets are derecognized with any associated gains or losses recognized in the Consolidated Statements of Comprehensive Income.
(f) Impairment of non-financial assets
The carrying amounts of non-financial assets, excluding inventories and deferred income tax assets, are reviewed for impairment (or impairment reversal) at each reporting date, or whenever events or changes in circumstances indicate the carrying amounts may not be recoverable (or indicate that a previous impairment may have reversed). In making this determination, the Company considers both internal and external information, in accordance with IAS 36, Impairment of Assets, to determine whether there is an indicator of impairment or impairment reversal and, accordingly, whether quantitative testing is required. Reviews are undertaken on an asset-by-asset basis, except where the recoverable amount for an individual asset cannot be determined, in which case the review is undertaken at the Cash Generating Unit ("CGU") level.
If the carrying amount of a CGU or non-financial asset exceeds the recoverable amount, being the higher of its fair value less costs of disposal ("FVLCD") and its value-in-use, an impairment expense is recognized as the excess of the carrying amount over the recoverable amount. With respect to CGUs, impairment losses are allocated first to reduce the carrying amount of any goodwill allocated to the CGUs, if any, and then to reduce the carrying amounts of the other assets in the CGU on a pro-rata basis.
Where the recoverable amount is assessed using discounted cash flow techniques, the estimates are based on detailed mine or production plans. The mine plan is the basis for forecasting production output in each future year and for forecasting production costs. For value-in-use calculations, production costs and output in the mine plan may be revised to reflect the continued use of the asset in its present form.
Non-financial assets that have previously been impaired are tested for a possible reversal of the impairment whenever events or changes in circumstances indicate that the impairment may have reversed, or may have partially reversed. In these instances,

13 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

the impairment loss is reversed to the recoverable amount but not beyond the carrying amount, net of amortization, that would have arisen if the prior impairment loss had not been recognized. Goodwill impairments are not reversed.
(g) Provisions
Provisions are recognized when the Company has a present obligation (legal or constructive), as a result of past events, and it is probable that an outflow of resources that can be reliably estimated will be required to settle the obligation. Provisions are measured at the present value of the expenditures expected to be required to settle the obligation using a pre-tax rate that reflects current market assessments of the time value of money and the risks specific to the obligation.
Decommissioning liabilities
The Company’s mining and exploration activities are subject to various governmental laws and regulations relating to the protection of the environment. These environmental regulations are continually changing, and the Company has made, and intends to make in the future, expenditures to comply with such laws and regulations. The timing of these expenditures is dependent upon a number of factors including the life of the mine, the operating license conditions, and the laws, regulations, and environment in which the mine operates.
Decommissioning liabilities are recognized at the time an environmental disturbance occurs and are measured at the Company’s best estimate of the expected future cash flows required to reclaim the disturbance for each mine operation, which are adjusted to reflect inflation, and discounted to their present value. The inflation rate used is determined based on external forecasts for inflation in the country in which the related mine operates. Expected future cash flows reflect the risks and probabilities that alternative estimates of cash flows could be required to settle the obligation. The discount rate used is a pre-tax rate that reflects current market assessments of the time value of money specific to the currency in which the cash flows are expected to be paid. The discount rate does not reflect risks for which the cash flows have been adjusted. Significant estimates are involved in forming expectations of future activities and the amount and timing of the associated cash flows. Those expectations are based on existing environmental and regulatory requirements or, if more stringent, Company policies that give rise to a constructive obligation.
Upon initial recognition of a decommissioning liability, the corresponding cost is capitalized as an asset, representing part of the cost of acquiring the future economic benefits of the operation. The capitalized cost is recognized in mineral property and amortized in accordance with the Company's policy for the related asset.
The provision is progressively increased over the life of the operation as the effect of discounting unwinds, creating an expense included in finance expense on the Consolidated Statements of Comprehensive Income.
Decommissioning liabilities are adjusted for changes in estimates. Such adjustments, which are not the result of the current production of inventory, are accounted for as a change in the corresponding capitalized cost of the related assets, except where a reduction in the provision is greater than the unamortized capitalized cost of the related assets. In instances where the capitalized cost of the related assets is nil, or will be reduced to nil, the remaining adjustment is recognized in net earnings. If reclamation and restoration costs are incurred as a consequence of the production of inventory, the costs are recognized as a cost of that inventory. Factors influencing such changes in estimates include revisions to estimated reserves, resources and lives of mines; developments in technologies; regulatory requirements and environmental management strategies; changes in estimated costs of anticipated activities, including the effects of inflation; and movements in interest rates affecting the discount rate applied.
(h) Leases
At inception of a contract, the Company assesses whether a contract is, or contains, a lease. A contract is, or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.
At inception or on reassessment of a contract that contains a lease component, the Company allocates the consideration in the contract to each lease component on the basis of their relative standalone prices. As a lessee, the Company recognizes an ROU asset, which is included in mineral property, plant and equipment, and a lease liability at the commencement date of a lease. The ROU asset is initially measured at cost, which is composed of the initial amount of the lease liability adjusted for any lease payments made at or before the commencement date, plus any decommissioning and restoration costs, less any lease incentives received.
The ROU asset is subsequently depreciated from the commencement date to the earlier of the end of the lease term, or the end of the useful life of the asset. In addition, the ROU asset may be reduced due to impairment losses, if any, and adjusted for certain re-measurements of the lease liability.

14 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

A lease liability is initially measured at the present value of the lease payments that are not paid at the commencement date, discounted by the interest rate implicit in the lease, or if that rate cannot be readily determined, the incremental borrowing rate. Lease payments included in the measurement of the lease liability are composed of:
•fixed payments, including in-substance fixed payments, less any lease incentives receivable;
•variable lease payments that depend on an index or a rate, initially measured using the index or rate as at the commencement date;
•amounts expected to be payable under a residual value guarantee;
•exercise prices of purchase options if the Company is reasonably certain to exercise those options; and
•payments of penalties for terminating the lease, if the lease term reflects the lessee exercising an option to terminate the lease.
The lease liability is measured at amortized cost using the effective interest method. It is remeasured when there is a change in future lease payments arising from a change in an index or rate, or when there is a change in our estimate or assessment of the expected amount payable under a residual value guarantee, purchase, extension or termination option. Variable lease payments not included in the initial measurement of the lease liability are charged directly to net earnings.
The Company has elected not to recognize assets and lease liabilities for short-term leases that have a lease term of 12 months or less, and leases of low-value assets. Lease payments associated with these leases will be recognized as an expense over the lease term. The Company has elected to apply the practical expedient to account for each lease component and any non-lease components, except embedded derivatives accounted for separately, as a single lease component.
(i) Revenue recognition
Revenue from the sale of gold, including refined metal, and dore, is recognized when control over the metal is transferred to the customer. Transfer of control generally occurs when title has passed to the customer, the customer has assumed the significant risks and rewards of ownership of the asset and the Company has the right to payment for the delivery of the refined metal, or dore. On transfer of control, revenue and related costs can be measured reliably and it is probable that the economic benefits associated with the transaction will flow to the Company as payment is received on the date of or within a few days of transfer of control.
(j) Deferred Revenue
Deferred revenue is recognized in the consolidated statements of financial position when consideration is received prior to the sale of gold. Revenue is subsequently recognized in the consolidated statements of comprehensive income when control has been transferred to the customer. The Company recognizes the time value of money, where there is a significant financing component and the period between the payment by the customer and the transfer of the contracted goods exceeds one year. Interest expense on deferred revenue is recognized in finance costs in the consolidated statements of comprehensive income, unless capitalized to construction in progress in accordance with the Company’s policy on capitalized borrowing costs. The Company determines the current portion of deferred revenue based on quantities anticipated to be delivered over the next twelve months.
(k) Share-based compensation
The Company measures all equity-settled share-based awards made to employees and others providing similar services (collectively, “employees”) based on the fair value of the options or units on the date of grant.
The grant date fair value of options is estimated using an option pricing model and is recognized as compensation expense over the vesting period, based on the number of options that are expected to vest. A corresponding increase is recognized in equity. The grant date fair values of the Company’s equity-settled performance share units, and restricted share units are determined using an option pricing model and are recognized as compensation expense over the vesting period.
The Company awards cash-settled share-based compensation to directors and employees in the form of deferred share units and restricted share units. In accounting for these awards, the Company recognizes the fair value of the amount payable to employees, using the Black-Scholes option pricing model for certain units, as they are earned based on the estimated number of units that are expected to vest. Based on the plan, some units are initially measured at fair value and recognized as an obligation at the grant date using the Company's share price. The corresponding liability is re-measured at fair value on each reporting date and upon settlement, with changes in fair value recognized in Comprehensive Income for the period. The fair value of deferred share units and restricted share units is determined by reference to the Company’s share price when the units are awarded or re-measured.
The Company also maintains an employee share purchase plan. Under this plan, contributions by the Company’s employees are matched to a specific percentage by the Company and are recognized as an expense when the Company’s obligation to contribute arises.

(l) Income taxes
Income tax expense is comprised of current and deferred income tax. Current and deferred income taxes are recognized in earnings or loss except to the extent that they relate to a business combination, or to items recognized directly in equity or other comprehensive income ("OCI").
Current income taxes
Current income tax expense is the expected tax payable on the taxable income for the year, using tax rates enacted or substantively enacted at year end, adjusted for amendments to tax payable with respect to previous years.
Deferred income taxes
Deferred tax assets and liabilities are recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The following do not result in deferred tax assets or liabilities:
•temporary differences arising from the initial recognition of assets or liabilities, not arising in a business combination, that does not affect accounting or taxable profit;
•taxable temporary differences arising from the initial recognition of goodwill; and
•taxable temporary differences associated with investments in subsidiaries, associates, and interests in joint arrangements where the timing of the reversal of the temporary differences can be controlled by the parent and it is probable that the temporary difference will not reverse in the foreseeable future.
Deferred tax assets and liabilities are measured using the enacted or substantively enacted tax rates expected to apply when the asset is realized or the liability settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings or loss in the period that substantive enactment occurs except to the extent it relates to items recognized directly in equity or in other comprehensive income.
A deferred tax asset is recognized to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. To the extent that the Company does not consider it probable that a deferred tax asset will be recovered, the deferred tax asset is reduced to its recoverable amount. The Company makes estimates of the likelihood of whether or not all or some portion of each deferred income tax asset will be realized, which is impacted by interpretation of tax laws and regulations, historic and future expected levels of taxable income, timing of reversals of taxable temporary timing differences, and tax planning initiatives. Levels of future taxable income are affected by, among other things, market gold prices, production costs, quantities of proven and probable gold reserves, interest rates, and foreign currency exchange rates.
Deferred tax assets and liabilities are offset when there is a legally enforceable right to set off tax assets against tax liabilities and when they relate to the same taxable entity and income taxes levied by the same taxation authority and the Company intends to settle its tax assets and liabilities on a net basis.
Uncertain tax positions
Uncertainties exist with respect to the interpretation of complex tax regulations, changes in tax laws, and the amount and timing of future taxable income. Given the wide range of international business relationships and the long-term nature and complexity of existing contractual agreements, differences arising between the actual results and the assumptions made, or future changes to such assumptions, could necessitate future adjustments to taxable income and expense already recorded. The Company establishes provisions, based on reasonable estimates, for possible consequences of audits by the tax authorities of the respective countries in which it operates. The amount of such provisions is based on various factors, such as experience of previous tax audits and differing interpretations of tax regulations by the taxable entity and the responsible tax authority. Such differences of interpretation may arise on a wide variety of issues depending on the conditions prevailing in the respective subsidiary’s country of domicile.
(m) Earnings per share
Basic earnings per share is calculated based on the weighted average number of common shares and common share equivalents outstanding for the period. Diluted earnings per share is calculated using the treasury method, except when assessing the dilution impact equity-settled restricted share units, and performance shares units, where the if converted method is used. The treasury method assumes that outstanding stock options with an average exercise price below the market price of the underlying shares, are exercised and the assumed proceeds are used to repurchase common shares of the Company at the average market price of the common shares for the period. The if converted method assumes that all equity settled restricted share units, and performance share units have been converted in determining fully diluted loss per share, except where such conversion would be antidilutive.

(n) Financial instruments
The Company’s financial instruments are classified and subsequently measured as follows:

Asset / Liability |  |
Cash and cash equivalents |  | Amortized cost
Equity securities |  | Fair value through OCI
Amounts receivable |  | Amortized cost
Accounts payable and accrued liabilities |  | Amortized cost
Debt and financing obligations |  | Amortized cost
Non-hedged derivatives |  | Fair value through profit or loss
Cash flow hedging derivatives |  | Fair value through OCI

The Company's accounting policy for financial instruments is as follows:
Financial assets
Financial assets are classified as either financial assets at fair value through profit or loss, amortized cost, or fair value through other comprehensive income ("OCI"). The Company determines the classification of its financial assets at initial recognition.
i. Financial assets recorded at fair value through profit or loss
All financial assets not classified as amortized cost or fair value through other comprehensive income ("FVOCI") are classified and measured at fair value through profit or loss ("FVPL"). Gains or losses on these items are recognized in net earnings or loss.
ii. Amortized cost
Financial assets are classified at amortized cost if both of the following criteria are met and the financial assets are not classified or designated as at fair value through profit and loss: 1) the Company’s objective for these financial assets is to collect their contractual cash flows and 2) the asset’s contractual cash flows represent ‘solely payments of principal and interest’. The Company’s amounts receivable are recorded at amortized cost as they meet the required criteria.
iii. Fair value through OCI
For equity securities that are not held for trading, the Company can make an irrevocable election at initial recognition to classify the instruments at FVOCI, with all subsequent changes in fair value being recognized in other comprehensive income. This election is available for each separate investment. Under this FVOCI category, fair value changes are recognized in OCI while dividends are recognized in profit or loss. On disposal of the investment the cumulative change in fair value is not recycled to profit or loss, rather transferred to deficit. The Company has elected to account for equity securities within this manner.
iv. Reclassifications
Financial assets are not reclassified subsequent to their initial recognition, except in the period after the Company changes its business model for managing financial assets.
Financial liabilities
Financial liabilities, including accounts payable and accrued liabilities, as well as debt and financing obligations are accounted for at amortized cost.
Transaction costs associated with financial instruments, carried at fair value through profit or loss, are expensed as incurred, while transaction costs associated with all other financial instruments are included in the initial carrying amount of the asset or the liability. The amortization of debt issue costs is calculated using the effective interest method.
Derivative financial instruments
The Company may hold derivative financial instruments to hedge its risk exposure to fluctuations in commodity prices, including the Company’s final product, consumables and other currencies against the US Dollars. Derivative financial instruments are measured at fair value at each reporting period.
Non-hedged derivative financial instruments
All derivative instruments not designated in a hedge relationship that qualify for hedge accounting are classified as financial instruments at fair value through profit or loss. Changes in fair value of non-hedging derivative financial instruments are included in net earnings or loss as non-hedging derivative gains or losses.

Derecognition
The Company derecognizes a financial asset when the contractual rights to the cash flows from the financial asset expire, or it transfers the rights to receive the contractual cash flows in a transaction in which substantially all of the risks and rewards of ownership of the financial asset are transferred or in which the Company neither transfers nor retains substantially all of the risks and rewards of ownership and it does not retain control of the financial asset.
The Company derecognizes a financial liability when its contractual obligations are discharged or cancelled, or expire. The Company also derecognizes a financial liability when its terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. On derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in profit or loss.
Offsetting
Financial assets and financial liabilities are offset and the net amount presented in the statement of financial position when, and only when, the Company currently has a legally enforceable right to set off the amounts and it intends either to settle them on a net basis or to realize the asset and settle the liability simultaneously.
(o) Hedges
The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategies for undertaking hedge transactions. This process includes linking all derivative hedging instruments to forecasted transactions. Hedge effectiveness is assessed based on the degree to which the cash flows from the derivative contracts are expected to offset the cash flows of the underlying transaction being hedged.
When a derivative is designated as a cash flow hedging instrument, the effective portion of changes in fair value is recognized in other comprehensive income. For hedged items other than the purchase of non-financial assets, the amounts accumulated in other comprehensive income are reclassified to the consolidated statement of other comprehensive income when the underlying hedged transaction, identified at the inception of the hedge, affects profit or loss. When hedging a forecasted transaction that results in the recognition of a non-financial asset, the amounts accumulated in other comprehensive income are removed and added to the carrying amount of the non-financial asset.
Any ineffective portion of a hedge relationship is recognized immediately in net earnings or loss. When derivative contracts designated as cash flow hedges are terminated, expired, sold or no longer qualify for hedge accounting, hedge accounting is discontinued prospectively. Any amounts recorded in other comprehensive income up until the time the contracts do not qualify for hedge accounting remain in other comprehensive income.
Gains or losses arising subsequent to the derivative contracts not qualifying for hedge accounting are recognized in the period incurred and are recorded in net earnings or loss. If the forecasted transaction is no longer expected to occur, then the amounts accumulated in other comprehensive income are reclassified to net earnings or loss immediately.
(p) Business combinations
The Company recognizes and measures the assets acquired and liabilities assumed in a business combination based on their estimated fair values at the acquisition date, while transaction and integration costs related to business combinations are expensed as incurred. Any excess of the purchase consideration when compared to the fair value of the net tangible and intangible assets acquired, if any, is recorded as goodwill. An income, market or cost valuation method may be utilized to estimate the fair value of the assets acquired, liabilities assumed, if any, in a business combination. The income valuation method represents the present value of future cash flows over the life of the asset using: (i) discrete financial forecasts, which rely on management’s estimates of reserve and resource quantities, costs to produce and develop reserves and resources, revenues, and operating expenses; (ii) appropriate discount rates; and (iii) expected future capital requirements. The market valuation method uses prices paid for a similar asset by other purchasers in the market, normalized for any differences between the assets. The cost valuation method is based on the replacement cost of a comparable asset at the time of the acquisition adjusted for depreciation and economic and functional obsolescence of the asset.
Goodwill is measured as the excess of the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree, and the fair value of the acquirer’s previously held equity interest in the acquiree (if any) over the net of the acquisition-date amounts of the identifiable assets acquired and the liabilities assumed. If, after reassessment, the net of the acquisition-date amounts of the identifiable assets acquired and liabilities assumed exceeds the sum of the consideration transferred, the amount of any non-controlling interests in the acquiree and the fair value of the acquirer’s previously held interest in the acquiree (if any), the excess is recognized immediately in profit or loss as a bargain purchase gain.
When a business combination is achieved in stages, the Company’s previously held interests in the acquired entity are remeasured to its acquisition-date fair value and the resulting gain or loss, if any, is recognized in other comprehensive income. Amounts arising from interests in the acquiree prior to the acquisition date that have previously been recognized in other comprehensive income are reclassified to retained earnings, where such treatment would be appropriate if that interest were disposed of.

18 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

If the initial accounting for a business combination is incomplete by the end of the reporting period in which the combination occurs, the Company reports provisional amounts for the items for which the accounting is incomplete. Those provisional amounts are adjusted during the measurement period, or additional assets or liabilities are recognized, to reflect new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the amounts recognized as of that date.
Acquisitions:
The purchase consideration of the acquisition of a mining property determined to be an asset acquisition is allocated to the individual assets acquired and liabilities assumed based on their relative fair values.

4 | CHANGES IN ACCOUNTING STANDARDS

New Standards issued and adopted
The Company adopted the following accounting standards and amendments to accounting standards, effective January 1, 2024:
On January 23, 2020, the IASB issued amendments to IAS 1 Presentation of Financial Statements, to clarify the classification of liabilities as current or non-current. For the purposes of non-current classification, the amendments removed the requirement for a right to defer settlement or roll over of a liability for at least twelve months to be unconditional. Instead, such a right must have substance and exist at the end of the reporting period. The amendments also clarify how a company classifies a liability that includes a counterparty conversion option. The amendments state that:
•settlement of a liability includes transferring a company’s own equity instruments to the counterparty, and
•when classifying liabilities as current or non-current a company can ignore only those conversion options that are recognized as equity
The amendments have been adopted by the Company, however the amendments did not result in any changes to the financial statements.
Standards issued but not yet adopted
In May 2023, the IASB issued International Tax Reform—Pillar Two Model Rules, which amended IAS 12, Income Taxes, to introduce a temporary exception to the requirements to recognize and disclose information about deferred tax assets and liabilities related to Pillar Two income taxes, and targeted disclosure requirements for affected entities. The relief is effective immediately upon issuance of the amendments while the targeted disclosure requirements are effective for annual reporting periods beginning on or after January 1, 2023. The Company has applied the exception and is currently assessing the impact of the disclosure requirements on its consolidated financial statements. Based on the existing revenue thresholds applicable under the Pillar Two Model Rules, the Company will be within the scope of the rules starting with its 2025 fiscal year as gross revenues will have exceeded 750 million Euros for 2 consecutive years. As the legislation has not been enacted or substantively enacted in Canada, the Company continues to evaluate the impact of the legislation on its consolidated financial statements.
IFRS 18 - Presentation and Disclosure in Financial Statements replaces IAS 1 - Presentation of Financial Statements, which sets out presentation and disclosure requirements for financial statements. The changes, which mostly affect the income statement, include the requirement to classify income and expenses into three new categories – operating, investing and financing – and present subtotals for operating profit or loss and profit or loss before financing and income taxes. Further, operating expenses are presented directly on the face of the income statement – classified either by nature, by function, or using a mixed presentation. Expenses presented by function require more detailed disclosures about their nature.
IFRS 18 also provides enhanced guidance for aggregation and disaggregation of information in the financial statements, introduces new disclosure requirements for management-defined performance measures and eliminates classification options for interest and dividends in the statement of cash flows. IFRS 18 is effective for annual periods beginning on or after January 1, 2027. The Company is assessing the impact of IFRS 18 on the consolidated financial statements.
In May 2024, the IASB issued Amendments to the Classification and Measurement of Financial Instruments (Amendments to IFRS 9 and IFRS 7). The key changes included clarification on the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to financial liabilities settled through electronic payment system, including an option to utilize an accounting policy for early derecognition. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they meet the solely payments of principal and interest criterion, including financial assets that have environmental, social and corporate governance (ESG)-linked features and other similar contingent features. The IASB also added disclosure requirements to provide additional transparency regarding equity investments designated at fair value through other comprehensive income and financial instruments with contingent features, such as those related to ESG requirements.
The amendments are effective for annual periods beginning on or after January 1, 2026 with early application permitted. The Company is assessing the impact of these amendments on the consolidated financial statements.

5 | CRITICAL ACCOUNTING ESTIMATES AND JUDGEMENTS

The Company’s management makes judgements in its process of applying the Company’s accounting policies in the preparation of its consolidated financial statements. In addition, the preparation of the financial data requires that the Company’s management makes assumptions and estimates of the impacts of uncertain future events on the carrying amounts of the Company’s assets and liabilities at the end of the reporting period, and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those estimates as the estimation process is inherently uncertain. Estimates are reviewed on an ongoing basis based on historical experience and other factors that are considered to be relevant under the circumstances. Revisions to estimates and the resulting impacts on the carrying amounts of the Company’s assets and liabilities are accounted for prospectively.
Critical accounting estimates
The following is a list of the accounting estimates that the Company believes are critical, due to the degree of uncertainty regarding the estimates or assumptions involved and the magnitude of the asset, liabilities, revenue or expense being reported. Actual results may differ from these estimates.
Business combinations
Business combinations are accounted for using the acquisition method of accounting. The allocation of the purchase price requires estimates as to the fair value of acquired assets and liabilities. For material acquisitions, the Company engages independent appraisers to assist with the determination of the fair value of assets acquired, liabilities assumed, and goodwill, if any, based on recognized business valuation methodologies. The information necessary to measure the fair values as at the acquisition date of assets acquired and liabilities assumed requires management to make certain judgements and estimates, including but not limited to the most appropriate valuation methodology, estimates of mineral reserves and mineral resources of the assets acquired, value of resources outside life of mine plans including assumptions for market values per ounce, future production levels, future operating costs, capital expenditures, discount rates, future metal prices and long term foreign exchange rates. Changes to the preliminary measurements of assets and liabilities acquired may be retrospectively adjusted when new information is obtained until the final measurements are determined within one year of the acquisition date. The Company determined that the acquisition of Argonaut met the requirements to be accounted for as a business combination; refer to Note 6.
Impairment and reversal of impairment of mining interests
The Company utilizes the FVLCD methodology to calculate the recoverable value of its mineral properties. The estimated undiscounted cash flows used to assess recoverability of long-lived assets and to measure the fair value of the Company’s mining operations are derived from current life of mine plans, which are developed using short-term price forecasts reflective of the current price environment and management’s projections for long-term average metal prices. In addition to short and long-term metal price assumptions, other assumptions include estimates of other input costs; proven and probable mineral reserve estimates, including the timing and cost to develop and produce the reserves; value beyond proven and probable mineral reserve estimates in the mine plan, including the value of mineral resources outside the life of mine; estimated future closure costs; foreign exchange rates; and the use of appropriate discount rates.
In estimating undiscounted cash flows, assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of undiscounted cash flows from other asset groups. The Company’s estimates of undiscounted cash flows are based on numerous assumptions and it is possible that actual cash flows may differ significantly from estimates, as actual produced reserves, metal prices, commodity-based and other costs, and closure costs are each subject to significant risks and uncertainties. During the third quarter of 2024, the Company recognized a reversal of impairment expense of $57.1 million in respect of the Young-Davidson cash-generating unit ("CGU"). (Note 9 (i))
Amortization
The Company makes estimates of the quantities of proven and probable mineral reserves of its mines and the portion of mineral resources expected to be ultimately converted to mineral reserves. The estimation of quantities of mineral reserves and mineral resources is complex, requiring significant subjective assumptions that arise from the evaluation of geological, geophysical, engineering and economic data for a given ore body. This data could change over time as a result of numerous factors, including new information gained from development activities, evolving production history and a reassessment of the viability of production under different economic conditions. The Company forecasts prices of commodities, exchange rates, production costs, discount rates, and recovery rates. Changes in these inputs may change the economic status of mineral reserves and may result in mineral reserves and mineral resources being revised.
The Company uses estimated proven and probable mineral reserves, and an estimate of mineral resources as the basis for amortizing certain mineral property, plant and equipment. The physical life of these assets, and related components, may differ from the Company’s estimate, which would impact amortization expense. Plant and equipment not depleted on a unit of production basis based on recoverable ounces are depleted on a straight-line basis. Changes to estimates of the useful life and residual value may be impacted by the Company's mine plans and rate of usage of these plant and equipment.

|  | 2024 FINANCIAL REPORT

Inventory
The Company accounts for its ore stockpiles and in-process precious metals inventory using a process flow for applicable costs appropriate to the physical transformation of ore through the mining, crushing, leaching from heap leach operations, milling and gold recovery process. The Company estimates the expected ultimate recovery based on laboratory tests and ongoing analysis of leach pad kinetics in order to estimate the recoverable metals at the end of each accounting period. If the Company determines at any time that the ultimate recovery should be adjusted downward, then the Company will adjust the average carrying value of a unit of metal content in the in-process inventory and adjust upward on a prospective basis the unit cost of subsequent production. Should an upward adjustment in the average carrying value of a unit of metal result in the carrying value exceeding the realizable value of the metal, the Company would write down the carrying value to the realizable value.
Decommissioning liabilities
The Company makes estimates of the timing and amount of expenditures required to settle the Company’s decommissioning liabilities. The principal factors that can cause expected future expenditures to change are: the construction of new processing facilities; changes in the quantities of material in reserves and a corresponding change in the life of mine plan; changing ore characteristics that ultimately impact the environment; changes in water quality that impact the extent of water treatment required; and changes in laws and regulations governing the protection of the environment. In general, as the end of the mine life nears, the reliability of expected cash flows increases, but earlier in the mine life, the estimation of a decommissioning liability is inherently more subjective.
Critical accounting judgements
The following are critical judgements that management has made in the process of applying accounting policies that may have a significant impact on the amounts recognized in the consolidated financial statements.
Indicators of impairment and reversal of impairment
The Company considers both external and internal sources of information in assessing whether there are any indications that CGUs are impaired or reversal of impairment is needed. External sources of information the Company considers include changes in the market, economic and legal environment in which the Company operates that are not within its control and are expected to affect the recoverable amount of CGUs. Internal sources of information the Company considers include the manner in which mineral properties and plant and equipment are being used or are expected to be used and indications of changes in the economic performance of the assets. The primary external factors considered are changes in forecast metal prices, changes in laws and regulations and the Company's market capitalization relative to its net asset carrying amount. Primary internal factors considered are the Company's current mine performance against expectations, changes in mineral reserves and resources, life of mine plans and exploration results.

6 | ACQUISITION OF ARGONAUT GOLD INC

On July 12, 2024, the Company completed the acquisition of all of the issued and outstanding common shares of Argonaut not already held by Alamos ("Argonaut Transaction"). As part of the Argonaut Transaction, Alamos acquired Argonaut’s Magino mine, located adjacent to Alamos’ Island Gold mine in Ontario, Canada. Through the use of shared infrastructure, Alamos expects to benefit from immediate and long-term synergies. Argonaut’s assets in the United States and Mexico were spun out as a newly created junior gold producer named Florida Canyon Gold. Under the terms of the Transaction, shareholders of Argonaut received 0.0185 of a Class A common share of Alamos and 0.1 of a common share of Florida Canyon Gold in exchange for each issued and outstanding common share of Argonaut ("exchange ratio").
Alamos issued approximately 20.4 million Class A Shares representing an equity value of $360.1 million on a fully diluted basis (exclusive of the shares previously held by Alamos). Additionally, the Company previously held a 13.8% interest in Argonaut as a result of a CAD$50 million private placement, entered into in contemplation of the acquisition, and which closed on April 4, 2024. The 13.8% interest was revalued as of the date of close and a fair value in respect of the equity investment of $58.9 million was recognized as part of the purchase consideration. A realized gain of $26.1 million, previously recognized in accumulated other comprehensive income was reclassified to retained earnings.
Concurrent with the closing of the Argonaut Transaction, Alamos completed a $10 million private placement into Florida Canyon Gold, increasing Alamos’ equity interest in Florida Canyon Gold to 19.9%.
The Company has determined that the Argonaut Transaction represents a business combination, with Alamos identified as the acquirer. The Company has consolidated the operating results, cash flows and net assets of the Magino mine and other acquired assets from July 12, 2024. For the period from July 12, 2024 to December 31, 2024, the Magino mine contributed revenue of $81.2 million and incurred earnings before income taxes of $6.6 million. If the acquisition of Magino Mine had taken place on January 1, 2024, pro-forma consolidated revenue and earnings before income taxes for the Company would have been $1,441.2 million and $418.2 million, respectively, for the year ended December 31, 2024.
Acquisition and integration related costs of $9.3 million have been expensed and are presented as part of Other Loss (Note 20). As of December 31, 2024, the Company had not yet completed the analysis to assign fair values to all assets acquired and

|  | 2024 FINANCIAL REPORT

liabilities assumed, and therefore the purchase price allocation for Argonaut is preliminary. The preliminary purchase price allocation will be subject to further refinement and may result in material changes to the estimated fair value of assets acquired and liabilities assumed.
In particular, the Company will continue to evaluate new information about the facts and circumstances that existed as of the acquisition date pertaining to the fair value of mineral properties, inventories, plant and equipment, deferred tax asset, debt and lease liabilities. The purchase price allocation adjustments can be made throughout the end of the Company's measurement period, which is not to exceed one year from the acquisition date.
The Company will continue to evaluate new information about the facts and circumstances that existed as of the acquisition date, specifically as it pertains to the fair value of mineral property, reclamation provision, lease liabilities, inventories and deferred taxes, the finalization of which could result in recognition of goodwill.

(i) Reversal of impairment
As at September 30, 2024, the Company identified an indication of impairment reversal for the Young-Davidson CGU driven by an increase in long-term gold price assumptions and consistent with the assumptions utilized by the Company in its valuation of Argonaut, and performed an impairment assessment to determine the recoverable amount of the Young-Davidson CGU. The recoverable amount was determined to be greater than the carrying amount which resulted in a reversal of all previous impairments of $57.1 million excluding goodwill, which was recorded to mineral property, plant and equipment and an intangible asset.
The recoverable amounts of the Company’s CGUs are based primarily on the future after-tax cash flows expected to be derived from the Company’s mining properties and represent each CGU’s FVLCD, a Level 3 fair value measurement. The income valuation method represents the present value of future cash flows over the life of the asset using: (i) discrete financial forecasts, which rely on management’s estimates of reserve and resource quantities, costs to produce and develop reserves, revenues, and operating expenses; (ii) appropriate discount rates; and (iii) expected future capital requirements.
The Company's impairment assessment incorporated the following key assumptions:
Weighted average cost of capital
Projected cash flows were discounted using an after-tax discount rate of 5% which represented the Company’s weighted average cost of capital and which included estimates for risk-free interest rates, market value of the Company’s equity, market return on equity, share volatility and debt-to-equity financing ratio.
Gold price and CAD:USD foreign exchange assumptions
The gold price and foreign exchange assumptions used in the cash flow projections beyond three years are based on management's judgement, including consideration of historical volatility and consensus analyst pricing. These assumptions were as follows:

| 2025 - 2027 | Long-term
USD:CAD | 1.35 | 1.33
Gold price ($) | 2,120-2,300 | 1,950 |

(ii) Acquisition of Orford
On April 3, 2024, the Company acquired all the issued and outstanding common shares of Orford not previously owned by the Company, by way of a plan of arrangement (the "Orford Arrangement"). Upon closing, former Orford shareholders were issued 0.005588 Alamos common shares for each common share of Orford outstanding, excluding 61,660,902 Orford common shares, or 27.5% interest, held by the Company at April 3, 2024.
Upon closing of the transaction, the Company issued 908,689 shares as part of the consideration. Common shares issued were valued at the closing share price on April 3, 2024 of CAD $19.87. The total consideration for the acquisition was $20.7 million, including transaction costs of $1.0 million.

25 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

Management determined that the acquisition of Orford did not meet the definition of a business combination in accordance with IFRS 3 - Business Combinations. Accordingly, the Company has accounted for the transaction as an asset acquisition. The allocation of the purchase price to the net assets acquired are as follows:

Purchase price: |
Fair value of total shares issued (Note 18) | $13.3 |
Fair value of 27.5% interest in Orford prior to acquisition | 5.0
125,852 replacement warrants issued | 0.8
93,958 replacement options issued | 0.6
Transaction costs | 1.0
Total consideration | $20.7 |
Net assets acquired |
Cash and cash equivalents | $1.2 |
Mineral property, plant and equipment | 21.1 |
Other assets | 0.2 |
Accrued liabilities and other liabilities | (1.8) |
| $20.7 |

The Orford mineral property has been recognized as part of the Corporate and Other reportable operating segment (Note 23).
(iii) Acquisition of Manitou Gold Inc. ("Manitou")
On May 23, 2023, the Company acquired all the issued and outstanding common shares of Manitou not previously owned by the Company, by way of a plan of arrangement (the "Arrangement"). Under the terms of the Arrangement, Manitou shareholders received 0.0035251 of an Alamos share for each Manitou share held. Prior to the closing of the Arrangement, the Company owned 65,211,077 Manitou shares, which represented approximately 19% of Manitou's basic common shares outstanding. Total consideration for the acquisition was $16.7 million, including transaction costs of $0.2 million. The acquisition was accounted for as an asset acquisition, and the majority of the consideration paid was recognized as mineral property. The Manitou mineral property has been recognized as part of the Island Gold reportable operating segment (Note 23).

Fair values of financial instruments
The following table shows the carrying amounts and fair values of financial assets and financial liabilities, including their levels in the fair value hierarchy. It does not include fair value information for financial assets and financial liabilities not measured at fair value if the carrying amount is a reasonable approximation of fair value. The Company does not have any non-recurring fair value measurements as at December 31, 2024. Levels 1 to 3 of the fair value hierarchy are defined based on the degree to which fair value inputs are observable or unobservable, as follows:
•Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;
•Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the net asset or liability, either directly or indirectly; and
•Level 3 inputs are unobservable (supported by little or no market activity).

1. On a gross basis, total derivatives recognized as at December 31, 2024 consist of total assets of nil, and total liabilities of $149.1 million ($9.1 million and $140.0 million classified as current and non-current liabilities, respectively) included in consolidated statements of financial position (December 31, 2023 - total assets of $6.6 million and total liabilities of $1.0 million).
Fair Value Methodology
The methods of measuring financial assets and liabilities have not changed during the year ended December 31, 2024.
The fair value of option and forward contracts are determined using a market approach with reference to observable market prices for identical assets traded in an active market. These are classified within Level 2 of the fair value hierarchy. The use of reasonably possible alternative assumptions would not significantly affect the Company’s results.
Derivative Instruments designated as cash flow hedges
Currency option and forward contracts and fuel option contracts
The Company enters into option and forward contracts to hedge against the risk of an increase in the value of the Canadian dollar and Mexican peso versus the US dollar. These option and forward contracts are for the purchase of local currencies and the sale of US dollars, which settle on a monthly basis, and the Company believes this is an appropriate manner of managing currency risk. The Company has designated options and forwards as cash flow hedges for the highly probable Canadian dollar and Mexican peso.
The Company also enters into option contracts to hedge against the risk of an increase in the price of diesel fuel. These option contracts are for the purchase of New York Harbour Ultra Low Sulfur Diesel ("ULSD") contracts, which settle on a monthly basis, and the Company believes this is an appropriate manner of managing price risk. The Company has designated these options as cash flow hedges for the highly probable consumption of diesel.

28 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

These currency option and forward and fuel option derivatives meet the hedge effectiveness criteria and are designated in a hedge accounting relationship as a result of the following factors:
•An economic relationship exists between the hedged items and hedging instrument, as notional amounts match and both the hedged item and hedging instrument fair values move in response to the same risk (foreign exchange risk and diesel price risk). Cash flows in relation to the designated hedged item and hedging instrument are matched since the option and forward contracts (hedging instrument) matures during the same month as the operational cash flows (hedged item) are expected to be incurred.
•The hedge ratio is one to one for this hedging relationship, as the hedged item is foreign currency risk and diesel price risk that is hedged with a foreign currency or diesel fuel hedging instrument using one unit of both the hedged and hedging item respectively.
•Credit risk is not material in the fair value of the hedging relationship.
The Company has identified two sources of potential ineffectiveness: 1) the timing of cash flow differences between the expenditure and the related derivative and 2) the inclusion of credit risk in the fair value of the derivative not replicated in the hedged item. The Company expects the impact of these sources of hedge ineffectiveness to be minimal. The timing of hedge settlements and incurred expenditures are closely aligned, as they are expected to occur within 30 days of each other. As noted above, credit risk is not a material component of the fair value of the Company’s hedging instruments, as all counterparties are reputable Canadian banking institutions and are highly rated.
For the years ended December 31, 2024 and 2023, the Company did not recognize any ineffectiveness on the hedging instruments.
The effective portion of the changes in fair value of the currency option and forward contracts for the years ended December 31, 2024 and 2023 recorded in accumulated other comprehensive loss is:

| December 31, 2024 | December 31, 2023

As at December 31, 2024, the Company held contracts to protect against the risk of an increase in the price of fuel. These collars totalling 1,512,000 gallons, ensure a minimum purchase call option of $2.50 per gallon and a maximum average sold put options of $2.33 per gallon, regardless of the movement in fuel prices during 2025. The fair value of these contracts at December 31, 2024 was a liability of $0.1 million (December 31, 2023 - liability of $0.2 million.)
Derivative Instruments not designated as cash flow hedges
Gold option contracts
As at December 31, 2024, the Company did not hold option contracts to protect against the risk of a decrease in the value of the gold price on a portion of gold sales. As at December 31, 2023, the Company held such contracts. The fair value of these contracts was a liability of $0.8 million at December 31, 2023.
Legacy Argonaut gold forward contracts
As at December 31, 2024, the Company held forward contracts that were acquired as part of the acquisition of Argonaut. These contracts, totaling 100,000 ounces in 2026 and 50,000 ounces in 2027, have an average forward price of $1,821 per ounce. These forward contracts mature monthly throughout 2026 and 2027. The fair value of these contracts was a liability of $140.0 million at December 31, 2024 (December 31, 2023 - nil).
Unrealized loss on financial instruments
For the year ended December 31, 2024, the Company realized losses of $9.3 million related to the settlement of option contracts (for the year ended December 31, 2023 - realized losses of $0.1 million). Total unrealized losses for the year ended December 31, 2024 was $24.2 million (for the year ended December 31, 2023 - unrealized losses of $0.9 million). Included in the unrealized loss is $25.0 million attributable to the Argonaut legacy hedges. The Company has elected to not apply hedge accounting to gold option and forward contracts, with changes in fair value recorded in net earnings.
Financial instruments and related risks
In the normal course of operations, the Company is exposed to credit risk, liquidity risk and the following market risks: commodity price, market price, interest rate and foreign currency exchange rate. The Company has developed a risk management process to identify, analyze and assess these and other risks, and has formed a Risk Committee to monitor all significant risks to the Company. The Board of Directors has overall responsibility for the oversight of the Company’s risk management framework, and receives regular reports from the Risk Committee.
Commodity price risk
The profitability of the Company’s mining operations is significantly affected by changes in the market price for gold. Gold prices fluctuate on a daily basis and are affected by numerous factors beyond the Company’s control. The supply and demand for gold, the level of interest rates, the rate of inflation, investment decisions by large holders of gold, including governmental reserves, and the stability of exchange rates can all cause significant fluctuations in gold prices. Such external economic factors are in turn influenced by changes in international investment patterns and monetary systems, and political developments. From time to time, the Company will enter into collars, options or other financial instruments to manage short term commodity price fluctuations.
For the year ended December 31, 2024, the Company’s revenues and cash flows were impacted by gold prices fluctuating from a low of $1,992 to a high of $2,787 per ounce. Metal price declines could cause the continued development of, and production from, the Company’s properties to be uneconomic.
As at December 31, 2024, the Company's commodity price risk associated with financial instruments primarily relates to changes in fair value caused by gold price on the legacy Argonaut gold forward contracts. If gold prices fluctuated by 10% from the December 31, 2024 price of $2,629 per ounce, with other variables held constant, the Company's earnings before taxes would increase or decrease by $39.4 million due to the change in fair value of the legacy Argonaut gold forward contracts.
Interest rate risk
Interest rate risk is the risk that the fair value or the future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The company has exposure to interest rate risk on the interest receipts on the cash and cash

30 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

equivalents and the interest payments on the revolving credit facility ("Facility") (Note 14). The interest incurred on the Facility is based on Adjusted Term SOFR Rates, which may fluctuate. A 100 basis point change in the interest rate would result in an increase or decrease of approximately $1.5 million in the Company's earnings before taxes. The Company has not entered into any derivative contracts to manage this risk.
Foreign currency exchange rate risk
Metal sales revenues for the Company are denominated in US dollars. The Company is exposed to currency fluctuations relative to the US dollar on expenditures that are denominated in Canadian dollars and Mexican pesos. These potential currency fluctuations could have a significant impact on production costs and thereby, the profitability of the Company. The Company is also exposed to the impact of currency fluctuations on its monetary assets and liabilities.
A 10% strengthening or deterioration of these currencies against the US dollar at each balance sheet date would have resulted in a gain or loss recorded in net earnings by the amounts shown below. This analysis assumes that other variables, in particular interest rates, remain constant.

| December 31, 2024 | December 31, 2023
Impact of a 10% change in foreign exchange rates |  |
Canadian dollar | $14.5 |  | $10.0 |
Mexican peso | 5.3 |  | 1.3 |

The currencies of the Company's financial instruments and other foreign currency denominated assets and liabilities based on notional amounts, denominated in U.S dollar equivalents were as follows:

| Canadian Dollars | Mexican Peso
| December 31, 2024 | December 31, 2023 | December 31, 2024 | December 31, 2023

Total exposure to currency risk | (144.8) |  | (88.1) |  | (48.0) |  | (12.2) |

Credit risk
Credit risk relates to receivables and other contracts, and arises from the possibility that any counterparty to an instrument fails to perform. For cash and cash equivalents, and receivables, the Company’s credit risk is limited to the carrying amount on the balance sheet. The Company manages credit risk by transacting with highly-rated counterparties and establishing a limit on contingent exposure for each counterparty based on the counterparty’s credit rating. Exposure on receivables is limited as the Company sells its products to a small number of organizations, on which the historical level of defaults is minimal.
The Company's maximum exposure to credit risk is as follows:

| December 31, 2024 | December 31, 2023
Cash and cash equivalents | $327.2 |  | $224.8 |
Derivative assets | — |  | 6.6 |
Other receivables | 4.2 |  | 11.2 |
Total financial instrument exposure to credit risk | $331.4 |  | $242.6 |

Liquidity risk
Liquidity risk is the risk that the Company will encounter difficulty in meeting obligations associated with financial liabilities that are settled by delivering cash or another financial asset. The Company manages this risk through regular monitoring of its cash flow requirements to support ongoing operations and expansionary plans. The Company ensures that there are sufficient committed loan facilities to meet its business requirements, taking into account anticipated cash flows from operations and holdings of cash and cash equivalents.

31 | Alamos Gold Inc.

|  | 2024 FINANCIAL REPORT

The Company’s future operating cash flow and cash position are highly dependent on gold prices, as well as other factors. Taking into consideration the Company’s current cash position, volatile equity markets, and global uncertainty in the capital markets, the Company is continually reviewing expenditures and assessing business opportunities to enhance liquidity in order to ensure adequate liquidity and flexibility to support its growth strategy, including the development of its projects, while continuing production at its current operations. A period of continuously low gold prices may necessitate the deferral of capital expenditures which may impact the timing of development work and project completion, as well as production from mining operations. In addition, in such a price environment, the Company may be required to adopt one or more alternatives to increase liquidity. The Company ensures that there are sufficient committed loan facilities to meet its business requirements, taking into account anticipated cash flows from operations and holdings of cash and cash equivalents.
(a) Contractual and other commitments
The following table shows the maturities of contractual and other commitments. The amount presented represents the future undiscounted principal and interest cash flows therefore do not equate to the carrying amounts on the consolidated statements of financial position.

24 | MANAGEMENT OF CAPITAL

The Company defines capital that it manages as its shareholders equity as well as debt and financing obligations. The Company’s objectives when managing capital are to safeguard the Company's ability to continue as a going concern so that it can continue to provide returns for shareholders and benefits for other stakeholders. At December 31, 2024, total managed capital was $3,584.2 million (2023 - $2,923.5 million).
The Company’s capital structure reflects the requirements of an entity focused on sustaining strong cash flows from its current mining operations and financing both internal and external growth opportunities and development projects.
