(tabular amounts expressed in thousands of US dollars, except share and per share amounts)

3 Material Accounting Policy Information, Estimates and Judgements

The Company’s management makes judgements in its process of applying the Company’s accounting policies in the preparation of these condensed interim 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 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.

In preparing the Company’s condensed interim consolidated financial statements for the three and nine months ended September 30, 2024, the Company applied the critical judgements and estimates disclosed in Note 3 of its consolidated financial statements for the year ended December 31, 2023 in addition to the critical judgment below, in addition to the accounting policies noted below.

Property, plant and equipment - Determination of available for use date

Judgment is required in determining the date that property, plant and equipment is available for use. As asset is considered available for use when it is in the location and condition necessary to operate in the manner intended by management.

The Mantoverde Development Project ("MVDP") consists of property plant and equipment that became available for use at different dates. When assessing when these assets are available for use, management considered several factors, the most significant of which are the asset commissioning and whether the assets are capable of operating near design capacity to ensure a reliable and consistent throughput rate to produce the expected quantity of outputs. The majority of the assets related to MVDP became available for use at the end of September 2024.

4 Adoption of New and Revised IFRS and IFRS Not Yet Effective

New IFRS Pronouncements

Issued and effective January 1, 2024

In January 2020 and October 2022, the IASB issued amendments to International Accounting Standards 1 ("IAS 1"), Presentation of Financial Statements, to clarify that liabilities are classified as either current or non-current, depending on the rights that exist at the end of the reporting period. Liabilities should be classified as non-current if a company has a substantive right to defer settlement for at least 12 months at the end of the reporting period. Rights are in existence if covenants are complied with at the end of the reporting period. Settlement refers to the transfer to the counterparty of cash, equity instruments, or other assets or services. In addition, the amendment required entities to disclose information to enable users of the financial statements to understand the risk that non-current liabilities with covenants could become repayable within twelve months. The amendments became effective January 1, 2024, with retrospective application required on adoption. The Company assessed the impact of this amendment and determined it does not have a significant effect on the Company's financial statements.

In September 2022, the IASB issued amendments to IFRS 16, Lease Liability in a Sale and Leaseback . The amendments require a seller-lessee to subsequently measure lease liabilities arising from a leaseback in a way

(tabular amounts expressed in thousands of US dollars, except share and per share amounts)

that it does not recognize any amount of the gain or loss that relates to the right of use it retains. The new requirements do not prevent a seller-lessee from recognizing in profit or loss any gain or loss relating to the partial or full termination of a lease. A seller-lessee applies the amendments retrospectively in accordance with IAS 8 Accounting Policies, Changes in Accounting Estimates and Errors to sale and leaseback transactions entered into after the date of initial application. The amendments became effective January 1, 2024. The Company assessed the impact of this amendment and determined it does not have a significant effect on the Company's financial statements.

In May 2023, the IASB issued amendments to IAS 7, Statement of Cash Flows and IFRS 7, Financial Instruments Disclosures to provide guidance on disclosures related to supplier finance arrangements that enable users of financial statements to assess the effects of these arrangements on the entity’s liabilities and cash flows and on the entity’s exposure to liquidity risk. The amendments became effective for annual periods beginning on or after January 1, 2024. The Company assessed the impact of this amendment and determined it does not have a significant effect on the Company's financial statements and has updated required disclosures accordingly.

Issued but not yet effective

In April 2024, the IASB issued a new IFRS accounting standard to improve the reporting of financial performance. IFRS 18 Presentation and Disclosure in Financial Statements replaces IAS 1 Presentation of Financial Statements. The standard will become effective January 1, 2027, with early adoption permitted. The Company is in the process of assessing the impact of this new standard on the Company's financial statements.

In May 2024, the IASB issued Amendments to IFRS 9 and IFRS 7, Amendments to the Classification and Measurement of Financial Instruments, which updated classification and measurement requirements in IFRS 9 Financial Instruments and related disclosure requirements in IFRS 7 Financial Instruments: Disclosures. The IASB clarified the recognition and derecognition date of certain financial assets and liabilities, and amended the requirements related to settling financial liabilities using an electronic payment system. It also clarified how to assess the contractual cash flow characteristics of financial assets in determining whether they solely meet the 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 added disclosure requirements for financial instruments with contingent features that do not relate directly to basic lending risks and costs, and amended disclosures relating to equity instruments designated at fair value through other comprehensive income. These amendments become effective January 1, 2026 with early application permitted. The Company is in the process of assessing the impact of this new standard on the Company's financial statements.

5. Acquisition of Compania Minera Sierra Norte S.A

In August 2024, the Company completed the acquisition of Compania Minera Sierra Norte, S.A. ("Sierra Norte"). On the closing of the transaction, Inversiones Alxar S.A. and Empresas COPEC S.A., collectively the "sellers" received the equivalent of US$40 million of shares of the Company. This resulted in the issuance of 6,139,358 Capstone common shares. The Company accounted for this acquisition as a purchase of assets. Accordingly, we allocated the sum of consideration paid and transaction costs incurred to the net assets acquired based on relative fair values.

6. Financial Instruments

Fair value of financial instruments

Certain of the Company's financial assets and liabilities are measured at fair value on a recurring basis and classified in their entirety based on the lowest level of input that is significant to the fair value measurement. Certain non-financial assets and liabilities may also be measured at fair value on a non-recurring basis. There are three levels of fair value hierarchy that prioritize the inputs to the valuation techniques used to measure fair value, with Level 1 having the highest priority. The levels and valuations techniques used to value the financial assets and liabilities are as follows:

Level 1 – Fair values measured using unadjusted quoted prices in active markets for identical instruments.

Short term investments and marketable securities are valued using quoted market prices in active markets. Accordingly, these items are included in Level 1 of the fair value hierarchy.

Level 2 – Fair values measured using directly or indirectly observable inputs, other than those included in Level 1.

Derivative instruments are included in Level 2 of the fair value hierarchy as they are valued using pricing models or discounted cash flow models. These models require a variety of inputs, including, but not limited to, market prices, forward price curves, yield curve and credit spreads. These inputs are obtained from or corroborated with the market. Also included in Level 2 are receivables from provisional pricing on copper concentrate and cathode sales because they are valued using quoted market prices derived based on forward curves for the respective commodities and published priced assessments.

Level 3 – Fair values measured using inputs that are not based on observable market data.

The Company’s policy for determining when a transfer occurs between levels in the fair value hierarchy is to assess the impact at the date of the event or the change in circumstances that could result in a transfer. There were no transfers between Level 1, Level 2 and Level 3 during the three and nine months ended September 30, 2024.

Financial instruments and related risks

The Company’s activities expose it to financial risks of varying degrees of significance which could affect its ability to achieve its strategic objectives for growth and shareholder returns. The principal financial risks to which the Company is exposed are commodity price risk, credit risk, foreign exchange risk, liquidity risk and interest rate risk. The Board of Directors has overall responsibility for the establishment and oversight of the Company’s risk management framework and reviews the Company’s policies on an ongoing basis. There have been no significant changes in the Company’s exposure to these financial risks.

Derivative instruments

As at September 30, 2024, the Company’s derivative financial instruments are composed of copper quotational pricing contracts, interest rate swap contracts, foreign currency zero-cost collars ("ZCC") and forward and swap contracts.

(tabular amounts expressed in thousands of US dollars, except share and per share amounts)

The Company operates on an international basis and therefore foreign exchange risk exposures arise from transactions denominated in a foreign currency. The Company's foreign exchange risk arises primarily with respect to the Chilean Peso ("CLP"), the Chilean Unidad de Fometo ("UF"), the Mexican Peso ("MXN") and the Canadian dollar ("CDN"). The UF is an artificial inflation-indexed monetary unit used in Chile to denominate certain contracts. The Company's cash flows from Chilean and Mexican operations are exposed to foreign exchange risk, as commodity sales are denominated in US dollars and a certain portion of operating and capital expenses is denominated in local currencies. As such, the Company may use foreign exchange forward and swap contracts and ZCCs to mitigate changes in foreign exchange rates.

The Company's outstanding derivative instruments as of September 30, 2024, are as follows:

12. Non-Controlling Interest

As part of the financing for the MVDP, Mitsubishi Materials Corporation ("MMC") acquired a 30% non-controlling interest in Mantoverde S.A., and agreed to make an additional $20 million contingent payment upon satisfaction of certain technical requirements relating to the expansion of the tailings storage facility.

In addition to the contingent arrangement, MMC agreed to provide a $60 million Cost Overrun Facility ("COF") in exchange for additional offtake of copper concentrate production under a 10-year contract (Note 25). The COF initially carried an interest rate of 3-month US$ LIBOR plus 1.70% and amortizing over 37 quarters from September 30, 2024. As a result of Interest Rate Benchmark Reform, the Company completed the transition from LIBOR to an adjusted secured overnight financing rate ("SOFR") with MMC. The transition resulted in a variable rate of SOFR compounded daily to a 3-month period plus 0.2616% per annum, with margins unchanged.

In addition to the COF, MMC advanced its pro-rata share of funding requests, which amounted to an additional $162.9 million, to Mantoverde in the form of shareholder loans forming part of the financing for the MVDP. Total funds advanced by MMC at September 30, 2024, including accrued interest of $15.3 million (December 31, 2023 - $6.0 million), was $245.6 million (December 31, 2023 - $195.9 million).

Mantoverde Development Project Facility

In order to fund the construction of MVDP, the Company secured a senior secured amortizing project debt facility in an aggregate amount of $520 million (the "MVDP Facility", comprising the “Covered Facility” $250 million, the “Uncovered Facility” $210 million, and the “ECA Direct Facility” $60 million). These project finance facilities are subject to affirmative, financial and restrictive covenants that include obligations to maintain the security interests in favour of the lenders over substantially all of the Mantoverde assets, insurance coverage, maintenance of offtake agreements, environmental and social compliance, restrictions on new financial indebtedness, distributions and dispositions, and compliance with certain financial ratios. As at September 30, 2024, the Company was in compliance with these covenants.

At September 30, 2024, $508 million was drawn on the MVDP Facility with $5.9 million recognized as an adjustment to record the debt at its fair value as required as part of the accounting for the business combination with Mantos (December 31, 2023 - $520 million and $6.6 million). This fair value adjustment amortizes down to its historical cost over the duration of the MVDP Facility.

(tabular amounts expressed in thousands of US dollars, except share and per share amounts)

Interest on borrowings under the MVDP Facility is payable quarterly. As a result of Interest Rate Benchmark Reform, the Company has completed the transition from LIBOR to an adjusted SOFR for its MVDP debt financing facility. The transition resulted in a variable rate of SOFR compounded daily to a 3-month period plus 0.2616% per annum, with margins unchanged (i.e., 1.65% for the Covered Facility and, with respect to the Uncovered Facility, a rate of 3.75% and, with respect to the ECA Direct Facility, a rate of 4.00% pre-completion of the MVDP, and decreasing to 3.50% and 3.75% respectively post-completion of the MVDP). Pursuant to the Covered Facility, an export credit agency guaranteed premium of 2.05% per annum is also payable quarterly and calculated over amounts outstanding under the Covered Facility. The MVDP Facility is secured by a comprehensive security package covering substantially all of the Mantoverde assets. The MVDP Facility amortizes from the earlier of September 30, 2024 and 180 days after project completion until December 2030 for the Uncovered Facility and December 2032 for the Covered Facility and ECA Direct Facility.

To mitigate the risk of movements in interest rates, and in compliance with a covenant in the MVDP Facility, a subsidiary of the Company entered into a fixed-for-floating SOFR swap at 1.015% with floating rate of daily SOFR, compounded to a quarterly rate, plus 0.2616% adjustment. The fixed-for-floating swap notional represents the notional amount as of the reporting period. The derivative instruments are a series of quarterly contracts, with notional amounts in line with planned quarterly balances based on expected project finance debt drawdown and expected amortization.

Revolving Credit Facility

On September 22, 2023, Capstone amended its RCF to increase the aggregate commitments from $600 million to $700 million and extended the maturity from May 2026 to September 2027. The Amended RCF bears interest on a sliding scale of adjusted term SOFR plus a margin of 2.000% to 2.875%. This amendment was treated as an extinguishment of the previous debt facility, resulting in $2.7 million of deferred financing fees being written off during the year ended December 31, 2023.

The interest rate at September 30, 2024 was one-month adjusted term SOFR of 5.21% plus 2.000% (December 2023 - adjusted term SOFR of 5.46% plus 2.125%) with a standby fee of 0.45% (2023 – 0.48%) payable on the undrawn balance (adjustable in certain circumstances).

The RCF is secured against the present and future real and personal property, assets and undertakings of Capstone Copper other than defined excluded entities which comprise the Mantoverde mine property and the Santo Domingo development project property.

The RCF requires Capstone to maintain certain financial ratios relating to debt and interest coverage. Capstone was in compliance with these covenants as at September 30, 2024.

Surety Bonds

As at September 30, 2024, the Company has in place seven surety bonds totaling $260.8 million to support various reclamation and other obligation bonding requirements. These comprise $182.0 million securing reclamation obligations at Pinto Valley, $4.0 million provided as security as part of a power supply agreement at Pinto Valley, $2.0 million related to the construction of a port for the Santo Domingo development project in Chile, $29.5 million at Mantoverde, and $43.3 million at Mantos Blancos, respectively, securing reclamation obligations. The Company is also an Indemnitor to the surety bond provider for the surety bond obligations of Minto Metals Corp. ("Minto Metals") ( Note 17 ).

15. Deferred Revenue

Silver Precious Metals Purchase Arrangement ("Silver PMPA")

On February 19, 2021, Capstone Mining concluded the Silver PMPA with Wheaton Precious Metals ("Wheaton") whereby Capstone received an upfront cash consideration of $150 million against delivery of 50% of the silver production from the Cozamin mine until 10 million ounces have been delivered, thereafter dropping to 33% of silver production for the remaining life of mine. In addition to the upfront cash consideration of $150 million, as silver is delivered under the terms of the Silver PMPA, the Company receives cash payments equal to 10% of the spot silver price at the time of delivery for each ounce delivered to Wheaton. The Silver PMPA is effective December 1, 2020. Wheaton has been provided certain security in support of the Company’s obligations under the Silver PMPA.

The Company recorded the upfront cash consideration received of $150 million as deferred revenue and recognizes amounts in revenue as silver is delivered under the Silver PMPA. Capstone determines the amortization of deferred revenue to the consolidated statements of income (loss) on a per unit basis using the estimated total number of silver ounces expected to be delivered over the life of the Cozamin mine. The amortization rate requires the use of proven and probable mineral reserves and certain mineral resources which management is reasonably confident will be transferred to mineral reserves. The Company estimates the current portion of deferred revenue based on deliveries anticipated over the next twelve months. During the three and nine months ended September 30, 2024, the Company delivered 163,331 and 446,705 ounces (2023 - 132,856 and 419,241 and ounces) of silver to Wheaton under the Silver PMPA.

The agreement with Wheaton includes a completion test which requires the completion of the paste backfill plant by December 31, 2023 and production of at least 105,000 cubic meters of suitable paste backfill for use in the underground operations at Cozamin over a consecutive 90-day period. During Q2 2024, the Company reached an agreement with Wheaton to extend the completion test period of the use of suitable paste backfill in the underground operations to September 30, 2024. During September 2024, the completion test was achieved.

Gold Precious Metals Purchase Arrangement ("Gold PMPA")

On April 21, 2021, Capstone Mining received an early deposit of $30 million ("the Early Deposit") in relation to the Gold PMPA at Santo Domingo with Wheaton effective March 24, 2021. If completion has not been achieved on or before the third anniversary date of receiving the early deposit, and early deposit delay payment will be triggered that would require the Company to sell and deliver 104 ounces of refined gold per month until the earlier of: the month completion is achieved, the month in which the early deposit is repaid to Wheaton or the month which refined gold is first sold and delivered to Wheaton. In the fourth quarter of 2023, the Company recorded an obligation under the gold stream of $7.1 million. As of September 30, 2024, the value of the obligation was $7.3 million.

Additional deposits of $260 million are to be received under the Gold PMPA over the Santo Domingo development project construction period, subject to sufficient financing having been obtained to cover total expected capital expenditures and other customary conditions, for total consideration of $290 million (collectively "the Deposit"). Wheaton will receive 100% of the gold production from the Company's Santo Domingo development project until 285,000 ounces have been delivered, thereafter dropping to 67% of the gold production for the remaining life of mine.

In addition to the deposits of $290 million, as gold is delivered under the terms of the Gold PMPA, Capstone receives cash payments equal to 18% of the spot gold price at the time of delivery for each ounce delivered to Wheaton, until the Deposit has been reduced to zero, thereafter increasing to 22% of the spot gold price upon delivery. Wheaton has been provided certain security in support of the Company’s obligations under the Gold PMPA. The initial term of the Gold PMPA is 20 years.

In June 2024, Canada enacted the Global Minimum Tax ("GMT") that was developed within the framework of the Organization for Economic Co-operation and Development ("OECD")'s Pillar Two Model rules, with effect from January 1, 2024. The Company applied the mandatory temporary exception to the recognition and disclosure for deferred taxes related to OECD Pillar Two income taxes under IAS 12 Income Taxes . No current taxes related to the GMT have been recorded, as the Company falls within the safe harbour provisions provided within the framework.

Minto Obligation

In June 2019, the Company completed the sale of its 100% interest in the Minto mine to Pembridge Resources PLC ("Pembridge"). In conjunction with the sale, Minto Metals Corp. ("Minto Metals") posted a surety bond to

Capstone Copper Corp.

Notes to the Condensed Interim Consolidated Financial Statements

(tabular amounts expressed in thousands of US dollars, except share and per share amounts)

cover potential future reclamation liabilities. While this surety bond is outstanding, the Company remains an indemnitor to the surety bond provider for Minto Metal's surety bond obligations in the Yukon.

In May 2023, Minto Metals announced that it had ceased all operations at the Minto mine located within the Selkirk First Nation's territory in central Yukon Territories and that the Yukon Government assumed care and control of the site. As Minto Metals had defaulted on the surety bond, in Q2 2023 Capstone recognized an initial liability of approximately US$55 million (C$72 million) related to the Company's obligations towards the issuer of the surety bond. In estimating the provision, the Company has made assumptions regarding the timing of cash outflows and discount rate. Due to the associated uncertainty of the timing of cash outflows, it is possible that estimates may need to be revised. The Company's exposure on calls against the surety bond is capped at approximately C$72 million therefore the timing of cash outflows and changes in the C$:US$ exchange rate are the largest contributors to the measurement uncertainty.

As at September 30, 2024, the Company has made payments of $26 million (December 31, 2023 - $10.4 million) to the Yukon Government for reclamation work performed. As at September 30, 2024, the Company has reclassified C$38.4 million (US$28.4 million) to other liabilities.

18. Share Capital

Authorized

An unlimited number of common voting shares without par value.

On February 8, 2024, the Company and Orion Fund JV Limited, Orion Mine Finance Fund II LP and Orion Mine Finance (Master) Fund I-A LP (collectively, “Orion”) closed a bought deal financing with a syndicate of underwriters ("the Offering"). Pursuant to the Offering, the Underwriters purchased on a bought deal basis from the Company and Orion, a total of 68,448,000 common shares of Capstone (“Common Shares”) at a price of C$6.30 per Common Share (the "Offering Price"), which included the exercise in full of the Underwriters' overallotment option of 8,928,000 Common Shares from the Company, for aggregate gross proceeds under the Offering of C$431,222,400.

In connection with the Offering, 56,548,000 Common Shares were issued by the Company for gross proceeds to the Company of C$356.3 million and 11,900,000 shares were sold by Orion for gross proceeds to Orion of C$75.0 million. The Company did not receive any proceeds from the secondary sale, which were paid directly to Orion.

In August 2024, the Company acquired Compania Minera Sierra Norte, S.A. ("Sierra Norte"). On the closing of the transaction, the equivalent of US$40 million of shares of the Company was issued. This resulted in the issuance of 6,139,358 Capstone common shares. Refer to Note 5 for further details on the acquisition.

Stock options

Pursuant to the Company’s amended stock option plan, directors may authorize the granting of options to directors, officers and employees of the Company to a maximum of 10% of the issued and outstanding common shares at the time of grant, with a maximum of 5% of the Company’s issued and outstanding shares reserved for any one person annually. Options granted under the plan have a term not to exceed five years, with the vesting term at the discretion of the Board. The exercise price of options granted are denominated in Canadian dollars (“C$”).

Notes to the Condensed Interim Consolidated Financial Statements Three and Nine Months Ended September 30, 2024 and 2023

(tabular amounts expressed in thousands of US dollars, except share and per share amounts)

Under the SUP, PSU and RSU obligations can be settled in cash, shares delivered from a Share Purchase Trust or a combination thereof, as determined by and at the discretion of the Human Resources and Compensation Committee of the Company’s Board of Directors. DSU obligations, under the Director’s Deferred Share Unit Plan, are redeemed in cash.

Deferred Share Units

The Company has established a Deferred Share Unit Plan (the “DSU Plan”) whereby DSUs are issued to directors as long-term incentive compensation. DSUs issued under the DSU Plan are fully vested upon issuance and entitle the holder to a cash payment only following cessation of service on the Board of Directors. The value of the DSUs when converted to cash will be equal to the number of DSUs granted multiplied by the quoted market value of a Capstone common share at the time the conversion takes place.

Compensation expense related to DSUs is recorded immediately and is adjusted at each reporting period to reflect the change in quoted market value of the Company’s common shares. DSU obligations, under the DSU Plan, are redeemed in cash.

Restricted Share Units and Performance Share Units

The Company has established a Share Unit Plan (the “Plan”) whereby RSUs and PSUs are issued as long-term incentive compensation. RSUs are issued to employees. PSUs are issued to executives.

RSUs issued under the Plan entitle the holder to a cash payment, shares delivered from a Share Purchase Trust or a combination thereof, at the end of the vesting period equal to the number of RSUs granted, multiplied by the quoted market value of a Capstone common share on the completion of the vesting period. RSUs granted to employees vest 1/3 per year over their three-year term.

PSUs issued under the Plan entitle the holder to a cash payment, shares delivered from a Share Purchase Trust or a combination thereof, at the end of a three-year performance period equal to the number of PSUs granted, adjusted for a performance factor and multiplied by the quoted market value of a Capstone common share on the completion of the performance period. The performance factor can range from 0% to 200% and is determined by comparing the Company’s total shareholder return to those achieved by a peer group of companies.

Compensation expense related to RSUs and PSUs is recorded over the three-year vesting period. The amount of compensation expense is adjusted at each reporting period to reflect the change in quoted market value of the Company’s common shares, the number of RSUs and PSUs expected to vest, and in the case of PSUs, the expected performance factor. RSU and PSU obligations, under the Share Unit Plan, can be settled in cash, shares delivered from a Share Purchase Trust or a combination thereof, as determined by and at the discretion of the Human Resources and Compensation Committee of the Company’s Board of Directors.

During the three and nine months ended September 30, 2024, the total fair value of DSUs, RSUs, and PSUs granted under the SUP was $0.01 million and $8.8 million (2023 – $0.1 million and $6.6 million), and had a weighted average grant-date fair value of $8.42 and C$7.25 (2023 – C$6.61 and C$6.02) per unit.

PSUs and RSU’s awarded to executives have been granted under a Treasury Share Unit Plan (“TSUP”). Treasury PSUs granted to executives vest after three years and are subject to a performance measure of 0% to 200%. Treasury RSUs granted to executives vest 1/3 per year starting on the first anniversary of the grant date. Canadian based executives are able to retain the PSUs and RSUs after vesting and elect when to redeem the units within 10 years of the grant date. Under the TSUP, PSU and RSU obligations can be settled in shares from treasury or cash, at the election of the Company.

During the three and nine months ended September 30, 2024, the total fair value of units granted under the TSUP was $nil and $4.6 million (2023 – $0.1 million and $2.4 million), and had a weighted average grant-date fair value of $nil and C$4.53 (2023 – $4.1 and C$3.99) per unit.
