Taseko Mines Limited (the "Company" or "Taseko") is a corporation governed by the British Columbia Business Corporations Act. The unaudited condensed consolidated interim financial statements of the Company as at and for the three and nine months ended September 30, 2025, comprise the Company and its controlled subsidiaries. The Company is principally engaged in the production and sale of metal concentrates, as well as related activities, including mine permitting and development, within the Province of British Columbia, Canada, and the State of Arizona, USA.

As a result of the Company's acquisition of Cariboo Copper Corporation ("Cariboo"), the financial results of the Company after March 25, 2024 reflect its 100% interest in Gibraltar mine ("Gibraltar") (Note 14). The financial results for the period up to and including March 25, 2024, reflect the Company's 87.5% interest in Gibraltar (Note 14).

2. MATERIAL ACCOUNTING POLICIES

2.1 Statement of compliance

These unaudited condensed consolidated interim financial statements have been prepared in compliance with IFRS Accounting Standards as issued by the International Accounting Standards Board ("IASB") ("IFRS Accounting Standards") as applicable to the preparation of interim financial statements under IAS 34, Interim Financial Reporting.

These unaudited condensed consolidated interim financial statements were authorized for issuance by the Company's Audit and Risk Committee on November 12, 2025.

2.2 Use of judgements and estimates

The preparation of these unaudited condensed consolidated interim financial statements in conformity with IFRS Accounting Standards requires management to make judgments, estimates, and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, income, and expenses. Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

The significant judgements made by management in applying the Company's accounting policies and the key sources of estimation uncertainty were the same as those applied to the audited annual consolidated financial statements as at and for the year ended December 31, 2024, except as noted below.

Partial Disposal of the New Prosperity Project

On June 5, 2025, the Company entered into a transaction with the Tsilhqot'in Nation and the Province of British Columbia (the "Province"), which involved the disposition of 22.5% of the common shares in 1280860 B.C. Ltd. ("1280860"), the entity which owns the New Prosperity Project as further described in Note 18.

The Company concluded it retains control of 1280860 under IFRS 10, Consolidated Financial Statements, as it retains the ability to direct the business activities that most significantly affect economic returns, including over strategy, budgeting, financing, performing technical and economic studies, and key personnel decisions as they relate to the advancement of the New Prosperity Project. The Tsilhqot'in Nation's consent rights are viewed as protective in nature, consistent with those held by a governing regulatory body.

2.3 New accounting standards issued but not yet effective

In 2024, the IASB issued IFRS 18, Presentation and Disclosure in Financial Statements. IFRS 18 introduces a new structure for the statement of profit or loss, requiring entities to present operating, investing, and financing categories, and enhances disclosures to improve comparability and transparency of financial performance. The standard is effective for annual reporting periods beginning on or after January 1, 2027, and is applied retrospectively. The Company is currently evaluating the impact of the amendments on its condensed interim consolidated financial statements.

The IASB also issued Amendments to the Classification and Measurement of Financial Instruments - Amendments to IFRS 9 and IFRS 7. These amendments 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 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 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. The amendments are effective for periods beginning on or after January 1, 2026, and are applied retrospectively. The Company is currently evaluating the impact of the amendments on its condensed interim consolidated financial statements.

In addition, the IASB issued the Annual Improvements to IFRS Standards 2021-2023 Cycle, which includes amendments to IFRS 1, IFRS 7, IFRS 9, IFRS 10, and IAS 7, aimed at improving consistency and application. The amendments are effective for periods beginning on or after January 1, 2026, and are applied retrospectively. The Company is currently evaluating their impact on its condensed interim consolidated financial statements.

4. COST OF SALES AND OTHER OPERATING (INCOME) COSTS

Site operating costs include personnel costs, operating waste stripping costs, repair and maintenance costs, consumables, operating supplies and external services.

During the nine months ended September 30, 2025, the Company recognized $5,624 of non-refundable scientific research and experimental development tax credits related to various activities at the Gibraltar mine up to 2023, as there is reasonable assurance that the Company met program conditions and that the credits will be used in future taxation periods. Consistent with the treatment of the corresponding qualifying expenses, $4,007 was recorded as other operating income and $1,617 as a reduction to property, plant and equipment.

Related to the acquisition of Cariboo in March 2024 (Note 12), changes in inventories of finished goods for the nine months ended September 30, 2024 included $17,986 in fair value adjustments for copper concentrate inventory held at March 25, 2024 that was sold subsequently. Changes in inventories of sulphide ore stockpiles for the three and nine months ended September 30, 2024 included $3,266 and $6,457, respectively, in fair value adjustments for sulphide ore stockpiles inventory held at March 25, 2024 that was processed and sold subsequently.

During the three and nine months ended September 30, 2024, the Company recognized costs of $4,098 and $12,009 related to the in-pit primary crusher relocation project.

In June 2024, operations at the Gibraltar mine were suspended for 18 days due to a strike by the unionized workforce which started on June 1, 2024. The resulting care and maintenance costs of $2,524 were expensed as incurred and do not form part of the cost of inventory and cost of sales. Operations at Gibraltar resumed on June 19, 2024, after the ratification of a new agreement by union members.

During the nine months ended September 30, 2024, the Company also recognized an insurance recovery of $26,290 related to the business interruption portion of an insurance claim for a component replacement in Concentrator #2.

5. DERIVATIVES AND OTHER FAIR VALUE INSTRUMENTS

a) Derivatives and other Financial Instruments measured at fair value

The following is a summary of the fair value gains or losses incurred during the three and nine months ended September 30, 2025 and 2024:

b) Copper Collars and Fuel Contracts

The following is a summary of the derivative transactions entered into by the Company during the three and nine months ended September 30, 2025 and 2024:

Details of the outstanding options contracts as at September 30, 2025 are summarized in the following table:

 c) Florence Copper Stream

On December 19, 2022, the Company signed agreements with Mitsui & Co. (U.S.A.) Inc. ("Mitsui") to form a strategic partnership to develop the Florence Copper project. Mitsui committed to an initial advance of US$50 million, with proceeds to be received in installments of US$10 million, to be used for the construction of the commercial production facility. The initial advance was in the form of a copper stream agreement (the "Copper Stream"), which obligates the Company to deliver 2.67% of the copper produced at Florence Copper, with Mitsui to make an ongoing payment equal to 25% of the monthly average LME price of copper on the day immediately preceding delivery under the contract. The Company received the final US$10 million instalment of the US$50 million Copper Stream on January 27, 2025.

Mitsui has the option to invest an additional US$50 million for a 10% equity interest in Florence Copper (the "Equity Conversion Option"). The Equity Conversion Option is exercisable by Mitsui at any time up to three years following completion of construction of the commercial production facility, as defined in the agreement. The Company completed construction of the commercial production facility on October 15, 2025, which set the expiry date for the exercise of the Equity Conversion Option as October 15, 2028. If Mitsui elects to exercise its Equity Conversion Option, the Copper Stream will terminate. If the Equity Conversion Option is not exercised, the Company will have the right to buy back 100% of the Copper Stream through a cash payment to Mitsui that would provide an internal rate of return of 10% on the stream deposits advanced (the "Buy Back Option"); otherwise, the Copper Stream will terminate once 40 million pounds of copper has been delivered under the agreement.

Taseko and Mitsui have also entered into an offtake contract for 81% of the copper cathode produced at Florence during the initial years of production. The contract will cease and be replaced with a marketing agency agreement if the Equity Conversion Option is exercised by Mitsui. Mitsui's offtake entitlement would also reduce to 30% if the Equity Conversion Option is not exercised, until such time as the Copper Stream deposit is reduced to nil. The offtake contract is also terminated in the event the Company exercises its Buy Back Option.

The Mitsui agreement is a financial liability measured at fair value each reporting period which includes the Copper Stream, Equity Conversion Option and Buy Back Option. The Company has determined the fair value of the Copper Stream and Buy Back Option to be $94,461 as at September 30, 2025, based on estimates of future production, future copper prices, and other relevant factors. The Equity Conversion Option has been estimated to have a nominal fair value at September 30, 2025, and since inception of the agreement.

6. FINANCE AND ACCRETION EXPENSE

For the three and nine months ended September 30, 2025, interest expense includes $536 and $1,461 (2024 -$324 and $1,035), respectively, from lease liabilities.

For the three and nine months ended September 30, 2025, interest expense capitalized relates to expenditures on the Florence Copper project. The capitalization rate for borrowing costs applied by the Company is 8.25%, commensurate with the coupon rate on the 2030 Notes.

7. INCOME TAX

For the nine months ended September 30, 2025, a deferred income tax recovery of $31,910 was recognized, which includes $9,238 related to the recognition of previously unrecognized net capital losses that were utilized for offsetting the capital gain recognized on the sale of a minority interest in the New Prosperity Project (Note 18). 

8. ACCOUNTS RECEIVABLE

9. INVENTORIES

10. OTHER FINANCIAL ASSETS AND DERIVATIVE LIABILITIES

Marketable securities and investments in privately owned companies are accounted for at fair value through other comprehensive (loss) income.

11. PROPERTY, PLANT AND EQUIPMENT

The following schedule shows the continuity of property, plant and equipment net book value by asset group for the nine months ended September 30, 2025:

During the three and nine months ended September 30, 2025, non-cash additions to Gibraltar capitalized stripping costs include $865 and $11,599 (2024 - $628 and $4,977), respectively, of depreciation on mining assets. Depreciation related to the right of use assets for the three and nine months ended September 30, 2025 was $3,546 and $10,022 (2024 - $3,074 and $8,762), respectively.

12. ACQUISITION OF CARIBOO COPPER CORPORATION

a) Acquisition of Cariboo from Dowa and Furukawa

On March 25, 2024 (the "Acquisition Date"), the Company completed the acquisition of 50% of Cariboo Copper Corporation ("Cariboo") from Dowa Metals & Mining Co. Ltd. ("Dowa") and Furukawa Co. Ltd. ("Furukawa"), resulting in an additional 12.5% effective interest in Gibraltar, bringing Taseko's total effective interest to 100%. Gibraltar is operated through a joint venture in which Gibraltar Mines Ltd, holds a 75% interest and Cariboo holds the remaining 25% interest.

The acquisition price payable to Dowa and Furukawa ranges from a minimum of $117 million to a maximum of $142 million, with payments spread over a 10-year period (the "Purchase Consideration") from the Acquisition Date. The amount and timing of these payments depend on LME copper prices and Gibraltar's cashflow. The fair value of the Purchase Consideration on the Acquisition Date was determined to be $71,116 (Note 14).

The purchase consideration was allocated to the assets acquired and liabilities assumed, including the additional 12.5% effective interest in the Gibraltar joint venture, based on their estimated fair values at the Acquisition Date. The fair value of the net assets acquired was recorded at $118,542. To account for the difference between the fair value of net assets acquired of $118,542 and the total fair value of consideration payable of $71,116, the Company recognized a bargain purchase gain on the statement of comprehensive (loss) income of $47,426 during the nine months ended September 30, 2024.

b) Deemed Disposition at Fair Value of 87.5% Gibraltar Interest on Acquisition of Control

Prior to March 25, 2024, the Company had joint control over the joint arrangement and proportionately consolidated its 87.5% effective interest in the Gibraltar joint venture's assets, liabilities, income and expenses. On March 25, 2024, the Company acquired the remaining 12.5% interest in the Gibraltar joint venture that it did not already own through its purchase of a 50% interest in Cariboo. As a result, the Company obtained control of the Gibraltar joint venture. This acquisition of control, required the Company to reassess its previously held 87.5% interest in Gibraltar and remeasure this interest at fair value as of the March 25, 2024 acquisition date, with any gains or losses recognized immediately in the statement of comprehensive (loss) income. Additionally, the Company was required to measure all identifiable assets acquired and liabilities assumed at their fair values on this deemed acquisition date.

The fair value of copper concentrate inventory as at the deemed acquisition date was determined to be $37,717 compared to the book value of $22,735, which resulted in a gain of $14,982 recognized in the statement of comprehensive (loss) income for the nine months ended September 30, 2024.

13. DEBT

a) Senior Secured Notes

On April 23, 2024, the Company completed an offering of US$500 million aggregate principal amount of senior secured notes (the "2030 Notes"). The 2030 Notes mature on May 1, 2030, and bear interest at an annual rate of 8.25%, payable semi-annually on May 1 and November 1.

The 2030 Notes are secured by liens on the shares of Taseko's wholly owned subsidiary, Gibraltar Mines Ltd., and the subsidiary's rights under the joint venture agreement related to Gibraltar, as well as the shares of Curis Holdings (Canada) Ltd. ("Curis"), Florence Holdings Inc. ("Florence Holdings"), and Cariboo. The 2030 Notes are guaranteed by each of Taseko's existing and future restricted subsidiaries.  The liens on the collateral securing the notes and the guarantees will be first liens, but ranked below the liens of the revolving credit facility. The Company is subject to certain restrictions on asset sales, issuance of preferred stock, dividends, and other restricted payments. There are no covenants regarding the Company's financial performance.

The 2030 Notes contain customary prepayment options, some of which represent embedded derivatives required to be recognized at fair value, with changes in the fair value recognized in the Company's statement of comprehensive (loss) income. The Company has estimated the prepayment options to have a nominal fair value.

b) Revolving Credit Facility

The Company has a US$110 million revolving credit facility (the "Facility") that is secured by first liens against Taseko's rights under the Gibraltar joint venture, as well as the shares of Gibraltar Mines Ltd., Curis, Florence Holdings, and Cariboo. The maturity date of the Facility is November 2, 2027. Amounts outstanding under the Facility bear interest at SOFR plus a margin of 4%, and undrawn amounts are subject to a standby fee of 1%. As at September 30, 2025, US$75 million was advanced under the Facility (2024 - nil).

The Facility has customary covenants for a revolving credit facility. Financial covenants include a requirement for the Company to maintain a senior debt to EBITDA ratio, an interest coverage ratio, a minimum tangible net worth, and a minimum liquidity amount, as defined under the Facility. The Company was in compliance with these covenants as at September 30, 2025. Between the end of the period and November 12, 2025, the Company had repaid the US$75 million balance outstanding on the facility.

c) Letter of Credit Facilities

The Gibraltar joint venture has in place a $7 million credit facility for the purpose of providing letters of credit ("LC") to key suppliers of Gibraltar to assist with ongoing trade finance and working capital needs. Any LCs issued under the facility are guaranteed by Export Development Canada ("EDC") under its Account Performance Security Guarantee program. The facility is renewable annually, is unsecured, and contains no financial covenants. As at September 30, 2025, $3.75 million is outstanding under this LC facility (2024 - $3.75 million).

The Company also has a US$4 million credit facility for the sole purpose of issuing LCs to certain key contractors in conjunction with the development of Florence Copper. Any LCs issued under this facility will also be guaranteed by EDC. The facility is renewable annually, is unsecured, and contains no financial covenants. As at September 30, 2025, no LCs were issued and outstanding under this LC facility (2024 - nil).

d) Gibraltar Equipment Loans

The equipment loans as at September 30, 2025, are secured by most of the existing mobile mining equipment at the Gibraltar mine. These loans commenced between December 2022 and December 2024, have monthly repayments over a term of 48 months, and carry interest rates ranging from 6.3% to 9.4%.

e) Florence Equipment Facility

In 2023, the Company secured a US$25 million Florence project loan from Bank of America, secured against specific equipment, with advances of US$15 million and US$10 million received in October 2023 and December 2023, respectively. On May 7, 2025, the Company extended borrowings under the facility with Bank of America for proceeds of US$3.25 million.

The facility contains no financial covenants and has monthly repayments over a term of 60 months. The equipment facility bears interest rates ranging from 7.2% to 9.3%.

f) Lease Liabilities

Lease liabilities have monthly repayment terms ranging from 12 to 72 months.

14. CARIBOO CONSIDERATION PAYABLE TO PRIOR OWNERS OF CARIBOO

In 2023 and 2024, the Company acquired Cariboo, which increased its effective ownership in Gibraltar from 75% to 100%. On March 15, 2023, the Company acquired Sojitz Corporation's ("Sojitz") 50% interest in Cariboo, resulting in a 12.5% increase in its effective interest in Gibraltar from 75% to 87.5%. On March 25, 2024, the Company acquired the remaining 50% of Cariboo from Dowa and Furukawa (Note 12). The liabilities arising from these transactions are collectively referred to as the "Cariboo consideration payable".

Sojitz Transaction

The acquisition price consisted of a minimum amount of $60 million payable over a five-year period ("Sojitz minimum payments") and potential contingent performance payments depending on Gibraltar copper revenues and copper prices over the next five years ("Sojitz Contingent Consideration"). There is no interest payable on the minimum amounts. An initial $10 million was paid to Sojitz upon closing and the remaining minimum amount is payable in $10 million annual instalments over five years thereafter.

The contingent performance payments are payable annually for five years only if the average LME copper price exceeds US$3.50 per pound in a year. The payments are calculated by multiplying Gibraltar copper revenues by a price factor, which is based on a sliding scale ranging from 0.38% at US$3.50 per pound copper to a maximum of 2.13% at US$5.00 per pound copper or above. Total contingent payments cannot exceed $57 million over the five-year period, limiting the acquisition cost to a maximum of $117 million.

The third annual instalment payment of $10 million was paid in February 2025 and the contingent payment of $6,645 for the 2024 calendar year was paid on April 1, 2025. The Sojitz minimum payments are a financial liability measured at amortized cost.  The Sojitz Contingent Consideration is a financial liability measured at fair value through profit and loss.

Dowa and Furukawa Transaction

Amounts owing by Cariboo to Dowa and Furukawa are by way of non-interest bearing secured and unsecured promissory notes of $45.5 million and $71.5 million, respectively, totaling $117 million (collectively, the "Cariboo Notes" or "Dowa and Furukawa minimum payments") which are guaranteed by Taseko. The secured Cariboo Notes are collateralized by Cariboo's 25% Gibraltar joint venture interest.  An initial payment of $5 million was made to Dowa and Furukawa against the Cariboo Notes on closing with the remaining principal payable in annual instalments over a 10-year period commencing in April 2026, with the secured Cariboo Notes repayable first.  At average LME copper prices below US$4.00 per pound, the annual repayments of the Cariboo Notes will be $5 million. This repayment amount will increase proportionally, reaching a maximum of $15.25 million when average LME copper prices are US$5.00 per pound or higher.

If average LME copper prices exceed an annual average of US$5.00 per pound or higher each year over the repayment period, up to $25 million in contingent consideration is payable by Taseko to Dowa and Furukawa (the "Dowa and Furukawa Contingent Performance Payments"). The Dowa and Furukawa Contingent Performance Payments is a financial liability measured at fair value through profit and loss. The Company estimates this liability to have nil value as at September 30, 2025 and December 31, 2024.

Annual principal payments cannot exceed 6.25% of Gibraltar's annual cashflow between 2025 and 2028, and 10% between 2029 and 2033. Any remaining balance of the Cariboo Notes will be paid as a final balloon payment in April 2034.  The fair value of the Cariboo Notes on the Acquisition Date was determined to be $71,116. The Dowa and Furukawa minimum payments are a financial liability measured at amortized cost, with estimated annual instalments considering the repayment mechanism described above.

As at September 30, 2025, the carrying value of the Cariboo consideration payable is as follows:

As at September 30, 2025, the current and long-term portions of the Cariboo consideration payable is as follows:

15. FLORENCE ROYALTY OBLIGATION

On February 2, 2024, Florence Holdings, an indirect wholly-owned subsidiary of Taseko, received US$50 million from Taurus Mining Royalty Fund L.P. ("Taurus"), pursuant to agreements entered into with Taurus for the sale of a perpetual gross revenue royalty interest in certain real property, mining and other rights held by Florence ("Florence Royalty Obligation"). The effective royalty rate is 2.05% of the gross revenue from the sale of all copper from Florence Copper for the life of mine. Proceeds from the royalty transaction were contributed to Florence Copper to fund the construction and development of the commercial production facility.

For accounting purposes, the purchase agreement is a financial liability at amortized cost. For the three and nine months ended September 30, 2025, the Company recorded accretion on the royalty obligation of $6,991 and $15,763 (2024 - $3,703 and $9,251), respectively, in the statement of comprehensive (loss) income. The current portion of the royalty obligation is an estimate based on anticipated gross revenue the next twelve months.

16. DEFERRED REVENUE

a) Customer Advance Payments

As at September 30, 2025, the Company had received advance payments from a customer on 1.1 million pounds of copper concentrate inventory (December 31, 2024 - 0.9 million pounds).

b) Gibraltar Silver Stream Agreement

In 2017 and as subsequently amended, the Company has entered into silver stream purchase and sale agreements with OR Royalties Inc. (formerly Osisko Gold Royalties Ltd.) (the "Gibraltar Silver Stream"), whereby the Company received upfront cash deposits payments totaling US$49.3 million for the sale of an equivalent amount of its 87.5% share of Gibraltar payable silver production until 6.3 million ounces of silver have been delivered. After that threshold has been met, 35% of an equivalent amount of Taseko's share of all future payable silver production from Gibraltar will be delivered.

On December 20, 2024, the Company amended the silver stream and received US$12.7 million for the sale of an equivalent amount of the remaining 12.5% share of Gibraltar payable silver production until 6.8 million ounces of silver have been delivered in aggregate. After that threshold has been met, 35% of an equivalent amount of Taseko's share of all future payable silver production from Gibraltar will be delivered.

The current portion of deferred revenue is an estimate based on deliveries anticipated over the next twelve months.

17. EQUITY

a) At-the-market Equity Offering Program

On May 3, 2023, the Company announced that it entered into an equity distribution agreement providing for an at-the-market equity offering program ("ATM") for potential share issuances at an aggregate offering price of up to US$50 million. The fully subscribed ATM was completed during the three months ended March 31, 2025. The Company issued a total of 22,627,320 shares under the ATM program in exchange for total gross proceeds of US$49,976, equivalent to $69,881.

b) Equity Offering

In October 2025, the Company entered into and closed an equity offering with a syndicate of underwriters for the issuance of 42,665,000 common shares at a price of US$4.05 per share. Proceeds, net of underwriter fees, from the offering amounted to US$165.0 million.

18. PARTIAL DISPOSAL OF NEW PROSPERITY PROJECT

On June 5, 2025, the Company entered into an agreement (the "Teẑtan Biny Agreement") with the Tsilhqot'in Nation and the Province, pursuant to which it transferred its New Prosperity mineral tenures and related assets to a wholly owned subsidiary, 1280860, and immediately thereafter transferred 22.5% of the common shares of 1280860 to the TN Interest Trust (the "Trust"), an irrevocable trust established for the benefit of the Tsilhqot'in Nation. In exchange, the Company received $75 million in cash, funded by a contribution from the Province to the Trust. Concurrent with the execution of the Teẑtan Biny Agreement, the Company also agreed to contribute $6 million to the Tsilhqot'in Nation to support community and land use planning initiatives, comprised of a $3 million payment at closing and three annual instalments of $1 million.

Under the Teẑtan Biny Agreement, the Company has agreed to not act as a proponent for development of the New Prosperity Project. If the Tsilhqot'in Nation consents to any ground-disturbing activity, the Trust will distribute the 22.5% equity interest directly to the Tsilhqot'in Nation.

Following the transaction, the Company retained a 77.5% shareholder interest in 1280860 and concluded that it continues to control the entity owning New Prosperity, as it continues to direct the activities that most significantly affect the entity's economic returns. As control was considered to be retained, the partial disposal was accounted for as an equity transaction under IFRS 10, Consolidated Financial Statements, with no gain or loss recognized in the statement of comprehensive (loss) income. The difference between the net consideration for the 22.5% shareholding interest of 1280860, less attributable transaction costs, and the carrying amount of that interest was recognized directly in equity. The non-controlling interest recognized as a result of the transaction was nominal, based on its proportionate share of 1280860's net assets.

The New Prosperity Transaction resulted in a net realized gain of $68.4 million recognized directly in equity. There was no net (loss) income or comprehensive (loss) income that was attributable to the non-controlling interest following the closing of the transaction.

19. SHARE-BASED COMPENSATION

a) Share Options

During the nine months ended September 30, 2025, the Company granted 2,813,300 (2024 - 2,956,000) share options to directors, executives and employees, exercisable at an average exercise price of $3.06 per common share (2024 - $1.86 per common share), vesting over two years and exercisable within five years of grant date. The total fair value of options granted was $4,867 (2024 - $3,104) based on a weighted average grant-date fair value of $1.73 (2024 - $1.05) per option.

The fair value of options was measured at the grant date using the Black-Scholes formula. Expected volatility is estimated by considering historic average share price volatility. The inputs used in the Black-Scholes formula are as follows:

23. FAIR VALUE MEASUREMENTS

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy establishes three levels to classify the inputs to valuation techniques used to measure fair value, based on the reliability of the inputs used to estimate the fair values.

Level 1: quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level 2: inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e., as prices) or indirectly (i.e., derived from prices); and

Level 3: inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The fair value of the senior secured notes, a Level 1 measurement, is determined based upon publicly available information. The fair values of the senior secured notes are $737,549 (December 31, 2024 - $735,038) and the face value is $696,050 (December 31, 2024 - $719,250) as at September 30, 2025. The Company has certain financial assets and liabilities that are measured at fair value on a recurring basis and uses the fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value, with Level 1 inputs having the highest priority.

There have been no transfers between fair value levels during the reporting period. The carrying value of cash, accounts receivables, accounts payable and accrued liabilities approximate their fair value as at September 30, 2025 due to their short-term nature.

The Company's metal concentrate sales contracts are subject to provisional pricing with the selling price adjusted at the end of the quotational period. At each reporting date, the Company's settlement receivable on these contracts are marked-to-market based on a quoted forward price for which there exists an active commodity market.

The Cariboo contingent performance payables (Note 14) and the Florence Copper Stream and buy back option (Note 5c), are each Level 3 instruments, as the inputs to their valuation are not based on observable market data.

24. SEGMENTED INFORMATION

Based on the primary locations where the Company generates revenue, or plans to generate revenue, the Company has three reportable segments reported to the Chief Executive Officer, the Chief Operating Decision Maker ("CODM") - Gibraltar, Florence Copper and Yellowhead. Corporate activities are not considered a reportable segment and are included as a reconciliation to total consolidated results. These corporate activities include corporate growth activities and groups that provide administrative, technical, financial and other support to the reportable segments. For producing segments, the Company evaluates performance based on earning (loss) from mining operations. Substantially all of the Company's earnings from mining operations, with associated revenue, production costs and depreciation, is attributable to the Gibraltar segment. Other operating expenses includes general and administrative, share-based compensation expense, project evaluation expense, changes in derivatives and other fair value instruments, and other income (expense). Net finance and other expense includes finance income and expenses, accretion expense, foreign exchange gains and losses, gain on Cariboo acquisition, and gain on acquisition of control of Gibraltar. Total assets do not include intra-group receivables between segments.
