The accompanying notes are an integral part of these condensed consolidated interim financial statements.

1. Reporting Entity

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 months ended March 31, 2026, comprise the Company and its controlled subsidiaries. The Company is principally engaged in the production and sale of copper metal and copper concentrates, as well as related activities, including mine permitting and development, within the Province of British Columbia, Canada, and the State of Arizona, USA.

2. Material Accounting Policies

2.1 Statement of compliance

These unaudited condensed consolidated interim financial statements have been prepared in compliance with International Financial Reporting Standards ("IFRS Accounting Standards") as issued by the International Accounting Standards Board ("IASB") 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 May 6, 2026.

2.2 Material accounting policies and significant accounting judgments and estimates

The preparation of these unaudited condensed consolidated interim financial statements in accordance 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, and revisions are recognized in the period in which the estimates are revised and in any future periods affected.

These interim financial statements should be read in conjunction with the Company's audited annual consolidated financial statements for the year ended December 31, 2025. The accounting policies applied are consistent with those disclosed in the annual financial statements, except as described in Note 2.3, and there have been no significant changes in accounting policy judgments, or key sources of estimation uncertainty during the period.

2.3 Adoption of new and amended IFRS Accounting Standards

In May 2024, the IASB 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 amendments are effective for periods beginning on or after January 1, 2026, and adoption of these amendments did not have a material effect on our condensed consolidated interim financial statements. For financial liabilities settled in cash using an electronic payment system, the Company applied the election to deem these financial liabilities to be discharged before the settlement date. The amendments have been applied retrospectively with no restatement of comparative information, in accordance with transition requirements on initial application of IFRS 9. The impact of adoption on the Company’s comparative cash balance as at December 31, 2025 was not material and is therefore not presented as a separate line item in the condensed consolidated interim statement of cash flows.

3. Revenues

4. Cost of Sales and Other Operating Costs

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

5. Derivatives and Other Fair Value Instruments

a) Derivatives and other financial instruments measured at fair value

The following is a summary of fair value gains and losses for the three months ended March 31, 2026 and 2025:

b) Copper Collar Contracts

The following summarizes derivative transactions entered into by the Company during the three months ended March 31, 2026. No such transactions were entered into during the same period in 2025.

Details of the outstanding options contracts as at March 31, 2026 are summarized in the following table:

⁽¹⁾ The copper collar payable was settled on April 1, 2026.

c) Florence Copper Stream

On December 19, 2022, the Company formed a strategic partnership with Mitsui to develop the Florence Copper project, which includes a copper stream arrangement (the "Copper Stream"), an equity conversion option, and a buyback option.

Under the Copper Stream, Mitsui advanced a total of US$50,000 in installments, which was fully received as of January 27, 2025. In return, the Company is obligated to deliver 2.67% of copper produced at Florence Copper to Mitsui, with Mitsui to make ongoing payments equal to 25% of the monthly average LME price of copper on the day immediately preceding delivery under the contract.

Mitsui has the option to convert the Copper Stream and invest an additional US$50,000 for a 10% equity interest in Florence Copper (the "Equity Conversion Option"). The Equity Conversion Option is exercisable up to October 15, 2028, which is the date three years after the Company completed construction of the commercial production facility, as defined in the agreement. If the Equity Conversion Option is exercised, the Copper Stream will terminate. If not exercised, the Company may repurchase the stream under the buyback option 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 upon delivery of 40 million pounds of copper 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 Copper Stream, Equity Conversion Option, and Buy Back Option are accounted for as a compound derivative instrument and measured at each reporting period. Fair value is determined using a valuation model that incorporates discounted cash flow techniques and Monte Carlo simulation. The valuation is categorized as a Level 3 fair value measurement due to the use of significant unobservable inputs, including long-term production forecasts and contract-specific assumptions.

The total fair value of the Copper stream as at March 31, 2026 is as follows:

6. Finance and Accretion Expense

For the three months ended March 31, 2026, interest expense includes $902 (2025 - $428), from lease liabilities. Borrowing costs are capitalized at an average rate of 8.25% (2025 - 8.25%).

7. Income Tax

8. Accounts Receivable

9. Inventories

10. Other Financial Assets and Derivative Liabilities

⁽¹⁾ The deferred share units ("DSUs") issued to member of the board of the Company that vest upon their completion of service are accounted for as cash-settled share-based payment awards. The DSU liability is recognized based on the quoted market value of the Company's common shares on the date of grant and is re-measured to fair value each reporting period thereafter to reflect changes in the market value of the Company's common shares.  The changes in fair value in the period are recorded in profit or loss as "Share-based compensation expense".

The total realized and unrealized fair value gain on copper collars for the three months ended March 31, 2026 amounted to $3,821 (2025 - loss of $22,864) (Note 5a).

11. Property, Plant and Equipment

The following schedule shows the continuity of property, plant and equipment net book value by asset group for the three months ended March 31, 2026:

During the three months ended March 31, 2026, the Company incurred wellfield development costs of $18,831, capitalized start-up and commissioning costs of $21,153, capitalized interest on borrowings of $7,221, and other capital expenditures of $2,254 in connection with the Florence Copper project.

During the three months ended March 31, 2025, the Company capitalized development costs of $83,227 and capitalized interest on borrowings of $5,756 for the Florence Copper project.

During the three months ended March 31, 2026, non-cash additions to capitalized stripping costs at Gibraltar included depreciation of mining assets totaling $1,951 (2025 - $5,936).

Depreciation expense related to right-of-use assets for the three months ended March 31, 2026 amounted to $2,237 (2025 - $2,799).

12. Debt

a) Senior Secured Notes

On April 23, 2024, the Company completed an offering of US$500,000 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 Copper Corp ("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 income (loss). The Company has estimated the prepayment options to have a nominal fair value.

b) Revolving Credit Facility

The Company has a US$110,000 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. Any 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 March 31, 2026 and December 31, 2025, no advances were outstanding under the Facility.

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 March 31, 2026.

c) Letter of Credit Facilities

The Gibraltar joint venture ("Gibraltar") has in place a $7,000 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 March 31, 2026, $3,750 is outstanding under this LC facility (December 31, 2025 - $3,750).

The Company also has a US$4,000 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 March 31, 2026, no LCs were issued and outstanding under this LC facility (December 31, 2025 - nil).

d) Gibraltar Equipment Loans

The equipment loans as at March 31, 2026, 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 Loans

In 2023, the Company secured a US$25,000 Florence project loan from Banc of America Leasing & Capital LLC, secured against specific equipment, with advances of US$15,000 and US$10,000 received in October 2023 and December 2023, respectively. On May 7, 2025, the Company extended borrowings under the facility with Banc of America for additional proceeds of US$3,300.

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 9.4%.

f) Lease Liabilities

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

13. Cariboo Consideration Payable to Prior Owners of Cariboo

In transactions occurring 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 Metals & Mining Co. Ltd. ("Dowa") and Furukawa Co. Ltd. ("Furukawa"). 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 $60,000 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 $10,000 was paid to Sojitz upon closing and the remaining minimum amount is payable in $10,000 annual instalments over five years thereafter. The Sojitz minimum payments are a financial liability measured at amortized cost, using an effective discount rate of 7.16%.

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 $117,000. The Sojitz Contingent Consideration is a financial liability measured at fair value through profit and loss.

The fourth annual instalment payment of $10,000 was paid in February 2026 and the contingent payment of $9,926 for the 2025 calendar year was paid on April 1, 2026.

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 $45,500 and $71,500, respectively, totaling $117,000 (collectively, the "Cariboo Notes") which are guaranteed by Taseko.

The secured Cariboo Notes are collateralized by Cariboo's 25% Gibraltar joint venture interest.  An initial payment of $5,000 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 $15,250 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 $25,000 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 March 31, 2026.

In combination, total annual payments to Dowa and Furukawa 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 Cariboo Notes are a financial liability measured at amortized cost, with estimated annual instalments considering the repayment mechanism described above.

As at March 31, 2026, the carrying value of the Cariboo consideration payable is as follows:

As at March 31, 2026, the current and long-term portions of the Cariboo consideration payable is as follows:

14. Florence Royalty Obligation

On February 2, 2024, Florence Holdings, an indirect wholly-owned subsidiary of Taseko, received US$50,000 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 Florence Royalty Obligation is a financial liability at amortized cost. For the three months ended March 31, 2026, the Company recorded accretion on the royalty obligation of $6,294 (2025 - $2,571), in the statement of comprehensive income (loss). The current portion of the royalty obligation is an estimate based on anticipated gross revenue over the next twelve months.

15. Deferred Revenue

a) Customer Advance Payments

As at March 31, 2026, the Company had received advance payments from a customer on 1.6 million pounds of copper concentrate inventory (December 31, 2025 - 1.0 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$49,300 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$12,700 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:

16. Share-based Compensation

a) Share Options

During the three months ended March 31, 2026, the Company granted 1,185,900 (2025 - 2,813,000) share options to directors, executives and employees, exercisable at an average exercise price of $9.54 per common share (2025 - $3.06 per common share), vesting over two years and exercisable within five years of grant date. The total fair value of options granted was $5,920 (2025 - $4,867) based on a weighted average grant-date fair value of $4.99 (2025 - $1.73) per option.

As at March 31, 2026, the outstanding options have the following ranges of exercise price and life remaining:

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

b) Deferred, Performance and Restricted Share Units

During the three months ended March 31, 2026, 82,195 DSUs were issued to directors (2025 - 264,900), 226,000 PSUs to senior executives (2025 - 741,600) and 203,000 RSUs to non-executives (2025 - 489,000).

The fair value of DSUs, PSUs and RSUs granted was $6,043 (2025 - $5,593), with a weighted average fair value at the grant date of $9.42 per unit for the DSUs (2025 - $3.06 per unit), $14.72 per unit for the PSUs (2025 - $4.43 per unit), and $9.54 per unit for the RSUs (2025 - $3.06). Deferred share units are accounted for as cash settled share-based compensation. Performance share units and restricted share units are accounted for as equity settled share-based compensation.

c) Share-based Compensation Summary

Share-based compensation expense is comprised as follows:

⁽¹⁾ Estimated forfeiture rate of 0% based on historically low level of forfeitures for stock option awards.

17. Earnings (loss) per Share

Earnings (loss) per share, calculated on a basic and diluted basis, is as follows:

18. Commitments and Contingencies

a) Commitments

The Company is a party to certain contracts relating to service and supply agreements. Future minimum payments under these agreements as at March 31, 2026, are presented in the following table:

As at March 31, 2026, the Company had commitments to incur capital expenditures of $586 (December 31, 2025 - $1,132) for Florence Copper and $10,232 (December 31, 2025 - $24,156) for Gibraltar.

b) Contingencies

There are no known contingencies that would impact the financial position or performance of the Company as at March 31, 2026.

19.   Supplementary Cash Flow Information

⁽¹⁾ Excludes accounts payable and accrued liability changes on capital expenditures.

20. 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 $727,483 (December 31, 2025 - $728,782) and the face value is $696,950 (December 31, 2025 - $685,300) as at March 31, 2026. 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 March 31, 2026 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 13) 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.

21. Related Parties

Compensation for key management personnel (including all members of the Board of Directors and executive officers) is as follows:

22. Segmented Information

The Company has identified three reportable segments, Gibraltar, Florence Copper, and Yellowhead, based on the primary locations where it generates, expects to generate, or plans to generate revenue. These segments are reviewed regularly by the Chief Executive Officer, who is the Chief Operating Decision Maker ("CODM"), for the purposes of resource allocation and performance assessment. Corporate activities do not meet the definition of a reportable segment and are therefore presented separately as a reconciliation to the consolidated totals. These activities primarily comprise corporate development initiatives and centralized functions that provide administrative, technical, financial, and other support to the operating segments. For operating segments in production, the CODM evaluates performance primarily based on earnings from mining operations. "Other operating expenses" include general and administrative costs, share-based compensation, project evaluation expenditures, changes in the fair value of derivatives and other financial instruments, and other (expense) income not directly attributable to mining operations. "Net finance and other expense" comprises finance income, finance expense, accretion expense, and foreign exchange loss. Total assets do not include intra-group receivables between segments.
