MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS

The consolidated financial statements, the notes thereto and other financial information contained in the Management's Discussion and Analysis have been prepared in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board and are the responsibility of the management of Taseko Mines Limited. The financial information presented elsewhere in the Management's Discussion and Analysis is consistent with the data that is contained in the consolidated financial statements. The consolidated financial statements, where necessary, include amounts which are based on the best estimates and judgment of management.

In order to discharge management's responsibility for the integrity of the financial statements, the Company maintains a system of internal control over financial reporting. These controls are designed to provide reasonable assurance that the Company's assets are safeguarded, transactions are executed and recorded in accordance with management's authorization, proper records are maintained and relevant and reliable financial information is produced. These controls include maintaining quality standards in hiring and training of employees, establishing policies and procedures, a corporate code of conduct and ensuring that there is proper accountability for performance within appropriate and well-defined areas of responsibility.

The Board of Directors is responsible for overseeing management's performance of its responsibilities for financial reporting and internal control over financial reporting. The Audit Committee, which is composed of non-executive directors, meets with management as well as the external auditors to ensure that management is properly fulfilling its financial reporting responsibilities to the Directors who approve the consolidated financial statements. The external auditors have full and unrestricted access to the Audit Committee to discuss the scope of their audits, the adequacy of the system of internal control over financial reporting and review financial reporting issues.

The consolidated financial statements have been audited by KPMG LLP, the Company's independent registered public accounting firm, in accordance with Canadian generally accepted auditing standards and the standards of the Public Company Accounting Oversight Board (United States).

MANAGEMENT'S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The Company's management, including the Chief Executive Officer and the Chief Financial Officer, is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) and Rule 15d-15(f) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act") as a process designed by, or under the supervision of, the Company's principal executive and principal financial officers and effected by the Company's Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards. The Company's internal control over financial reporting includes those policies and procedures that:

- pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company;

- 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

- 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.

The Company's management, under the supervision of the Chief Executive Officer and the Chief Financial Officer, assessed the effectiveness of the Company's internal control over financial reporting as defined in Rule 13a-15(f) and Rule 15d-15(f) under the Exchange Act as of December 31, 2020. In making this assessment, it used the criteria set forth in the Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). Based on this assessment, management has concluded that, as of December 31, 2020, the Company's internal control over financial reporting is effective based on those criteria.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2020 has been audited by KPMG LLP, the Company's independent registered public accounting firm, as stated in their report immediately preceding the Company's audited consolidated financial statements for the years ended December 31, 2020 and 2019.

Report of Independent Registered Public Accounting Firm

To the Shareholders and Board of Directors
Taseko Mines Limited

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Taseko Mines Limited. (the "Company") as of December 31, 2020 and 2019, the related consolidated statements of comprehensive income (loss), changes in equity, and cash flows for each of the years in the two-year period ended December 31, 2020, 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, 2020 and 2019, and its financial performance and its cash flows for each of the years in the two-year period ended December 31, 2020, 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, 2020, 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 24, 2021 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 Matters

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.

Valuation of goodwill and property, plant and equipment of the Curis cash generating unit

As discussed in Notes 2.4(f), 15 and 16 to the consolidated financial statements, the Company performs goodwill impairment testing at least annually and, for property, plant and equipment, whenever circumstances suggest that the carrying value may not be recoverable. If such indication exists, the recoverable amount of the cash generating unit ("CGU") associated with the goodwill and property, plant and equipment is estimated in order to determine the extent of the impairment, if any. The recoverable amount is the higher of fair value less costs of disposal and value in use and is estimated using discounted cash flows. Significant assumptions used in the determination of the recoverable amount included exploration potential, long-term commodity prices, discount rate, future capital requirements and operating performance. As of December 31, 2020, the carrying amount of goodwill and property plant and equipment of the Curis CGU was $5,250 thousand and $203,079 thousand, respectively.

| Taseko Mines Limited Page 3

We identified the valuation of goodwill and property, plant and equipment of the Curis CGU as a critical audit matter. Subjective auditor judgment was required in evaluating the significant assumptions used in the Company's determination of recoverable amount. Specifically, the number and complexity of significant assumptions were challenging to evaluate as minor changes to these assumptions had a significant effect on 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 related to the critical audit matter. This included controls related to the determination of the recoverable amount of the CGU, and the determination of exploration potential, long-term commodity prices, discount rate, future capital requirements and operating performance. We evaluated the professional qualifications, knowledge, skill, and ability of the Company's qualified persons responsible for determining the exploration potential. We compared the projected production information in the valuation model to the mine plans and to the mineral reserves estimates for consistency. We compared long-term commodity prices used in the valuation model to third party estimates. We compared future capital requirements and operating performance in the valuation model to the mine plans. We involved valuations professionals with specialized skills and knowledge, who assisted in: evaluating the discount rate used by comparing it against a discount rate range that was independently developed using publicly available benchmark data for comparable entities; and evaluating the long-term commodity prices by comparing them to third party estimates.

We have audited Taseko Mines Limited's (the "Company") internal control over financial reporting as of December 31, 2020, 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, 2020, 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 balance sheets of the Company as of December 31, 2020 and 2019, the related consolidated statements of comprehensive income (loss), changes in equity, and cash flows for each of the years in the two-year period ended December 31, 2020 and the related notes (collectively, the consolidated financial statements), and our report dated February 24, 2021 expressed an unqualified opinion on those consolidated financial statements.

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, included in the accompanying Management's Report on Internal Control over Financial Reporting. 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

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

1. REPORTING ENTITY

Taseko Mines Limited (the "Company" or "Taseko") is a corporation governed by the British Columbia Business Corporations Act. The consolidated financial statements of the Company as at and for the year ended December 31, 2020 comprise the Company, its subsidiaries and its 75% interest in the Gibraltar joint venture since its formation on March 31, 2010. The Company is principally engaged in the production and sale of metals, as well as related activities including mine permitting and development, within the province of British Columbia, Canada and the State of Arizona, USA. Seasonality does not have a significant impact on the Company's operations.

2. BASIS OF PREPARATION

2.1 Statement of compliance

These consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board.

These consolidated financial statements were authorized for issue by the Board of Directors on February 24, 2021.

2.2 Basis of measurement, judgment and estimation

These consolidated financial statements have been prepared on a historical cost basis except those measured at fair value through profit or loss, fair value through other comprehensive income and derivative financial instruments, which are measured at fair value.

These consolidated financial statements are presented in Canadian dollars, which is the Company's functional currency. Foreign currency monetary assets and liabilities are translated into Canadian dollars at the closing exchange rate as at the balance sheet date. Foreign currency non-monetary assets and liabilities, revenues and expenses are translated into Canadian dollars at the prevailing rate of exchange on the dates of the transactions. Any gains and losses are included in profit and loss. The Company's US subsidiary measures the items in its financial statements using the US dollar as its functional currency. The assets and liabilities of the US subsidiary are translated into Canadian dollars using the period end exchange rate. The income and expenses are translated into Canadian dollars at the weighted average exchange rates to the period end reporting date. Any gains and losses on translation are included in accumulated other comprehensive income ("AOCI"). All financial information presented in Canadian dollars has been rounded to the nearest thousand, unless otherwise noted.

The preparation of these consolidated financial statements in conformity with IFRS 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.

In the process of applying the Company's accounting policies, significant areas where judgment is required include the determination of a joint arrangement, determining the timing of transfer of control of inventory for revenue recognition, reserve and resource estimates, functional currency, determination of the accounting treatment of the advance payment under the silver purchase and sale agreement reported as deferred revenue (Note 19), provisions for environmental rehabilitation, determination of business or asset acquisition treatment, and recovery of other deferred tax assets.

On March 11, 2020, the World Health Organization declared the coronavirus ("COVID-19") outbreak a pandemic creating an unprecedented global health and economic crisis. COVID-19's impact on global markets has been significant. The duration and magnitude of COVID-19's effects on the economy, movement of goods and services across international borders, the copper market, and on the Company's financial and operational performance remains uncertain at this time. As of the date of these statements, there has not been any direct impact on the Company's operations as a result of COVID-19.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

The Company will continue to closely monitor the potential impact of COVID-19 on its business. Should the duration, spread or intensity of the COVID-19 pandemic deteriorate in the future, there could be a potentially material and negative impact on the Company's operating plan, its cash flows, and the valuation of its long-lived assets due to sustained decreases in metal prices, potential future decreases in revenue from the sale of its products and the profitability of its ongoing operations. Impacts from COVID-19 could also include a temporary cessation of mining operations at the Gibraltar Mine due to a localized outbreak amongst personnel at the mine site or in the Company's supply chain. The Company's access to financing to support the development of its other mineral properties, including the Florence Copper project, could also be negatively impacted or delayed as a result of COVID-19.

Significant areas of estimation include reserve and resource estimation; asset valuations and the measurement of impairment charges or reversals; valuation of inventories; plant and equipment lives; tax provisions; provisions for environmental rehabilitation, including determination of appropriate discount rates; valuation of financial instruments and derivatives; capitalized stripping costs and share-based compensation. Key estimates and assumptions made by management with respect to these areas have been disclosed in the notes to these consolidated financial statements as appropriate.

The accuracy of reserve and resource estimates is a function of the quantity and quality of available data and the assumptions made and judgment used in the engineering and geological interpretation and may be subject to revision based on various factors. Changes in reserve and resource estimates may impact the carrying value of property, plant and equipment; the calculation of depreciation expense; the capitalization of stripping costs incurred during production; and the timing of cash flows related to the provision for environmental rehabilitation.

Changes in forecast prices of commodities, exchange rates, production costs and recovery rates may change the economic status of reserves and resources. Forecast prices of commodities, exchange rates, production costs and recovery rates, and discount rates assumptions, either individually or collectively, may impact the carrying value of derivative financial instruments, provisions for environmental rehabilitation, inventories, property, plant and equipment, and intangibles, as well as the measurement of impairment charges or reversals.

2.3 Basis of consolidation

The consolidated financial statements comprise the financial statements of the Company and controlled entities as at December 31, 2020. Control is achieved 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.

The Company reassesses whether or not it controls an investee if facts and circumstances indicate that there are changes to one or more of the three elements of control. Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Assets, liabilities, income and expenses of a subsidiary acquired or disposed of during the year are included in the consolidated statement of comprehensive income (loss) from the date the Company gains control until the date the Company ceases to control the subsidiary. When necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies into line with the Company's accounting policies. All intercompany transactions between the subsidiaries of the Company are eliminated in full on consolidation.

The Company applies the acquisition method in accounting for business combinations. The consideration transferred by the Company to obtain control of a subsidiary is calculated as the sum of the acquisition-date fair values of assets transferred, liabilities incurred and the equity interests issued by the Company, which includes the fair value of any asset or liability arising from a contingent consideration arrangement. Acquisition costs are expensed as incurred.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

The Company recognizes identifiable assets acquired and liabilities assumed in a business combination regardless of whether they have been previously recognized in the acquiree's financial statements prior to the acquisition. Assets acquired and liabilities assumed are generally measured at their acquisition-date fair values.

Goodwill is stated after separate recognition of identifiable intangible assets. It is calculated as the excess of the sum of a) fair value of consideration transferred, b) the recognized amount of any non-controlling interest in the acquiree and c) acquisition-date fair value of any existing equity interest in the acquiree, over the acquisition-date fair values of identifiable net assets. If the fair values of identifiable net assets exceed the sum calculated above, the excess amount would be recognized in profit or loss immediately.

2.4 Significant Accounting Policies

(a) Revenue recognition.

Under IFRS 15, Revenue Contracts with Customers, revenue is recognized when a customer obtains control of the goods or services and the Company has satisfied its performance obligations. Determining the timing of the transfer of control, at a point in time or over time, requires judgment. Cash received in advance of meeting these conditions is recorded as advance payments or deferred revenue.

Under the terms of the Company's concentrate sales contracts, the final sales amount is based on final assay results and quoted market prices which may be in a period subsequent to the date of sale. Revenues for these sales, net of treatment and refining charges are recorded when the customer obtains control of the concentrate, based on an estimate of metal contained using initial assay results and forward market prices for the expected date that final sales prices will be fixed. The period between provisional pricing and final settlement can be up to four months. This settlement receivable is recorded at fair value each reporting period by reference to forward market prices until the date of final pricing, with the changes in fair value recorded as an adjustment to revenue.

(b) Cash and equivalents

Cash and equivalents consist of cash and highly-liquid investments having terms of three months or less from the date of acquisition and that are readily convertible to known amounts of cash. Cash and equivalents exclude cash subject to restrictions.

(c) Financial instruments

Financial assets and liabilities are recognized on the balance sheet when the Company becomes party to the contractual provisions of the instrument. The classification of financial instruments dictates how these assets and liabilities are measured subsequently in the Company's consolidated financial statements.

A financial asset is classified as measured at fair value and subsequently at either: amortized cost; Fair Value through Other Comprehensive Income (FVOCI); or Fair Value through Profit or Loss (FVPL). The classification of financial assets under IFRS 9 is generally based on the business model in which a financial asset is managed and its contractual cash flow characteristics.

A financial asset is measured at amortized cost if: (i) it is held within a business model whose objective is to hold assets to collect contractual cash flows; and (ii) its contractual terms give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding; and (iii) it is not designated as FVPL. This category of financial assets is subsequently measured at amortized cost using the effective interest method, and reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.

On initial recognition of an equity investment that is not held for trading, the Company may irrevocably elect to present subsequent changes in the investment's fair value in OCI. This election is made on an investment-by-investment basis. Equity investments measured at FVOCI are subsequently measured at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

All financial assets not classified as measured at amortized cost or FVOCI as described above are measured at FVPL. This includes all derivative financial assets. On initial recognition, the Company may irrevocably designate a financial asset as FVPL if doing so significantly reduces an accounting mismatch that would otherwise arise. Financial assets classified as FVPL are subsequently measured at fair value, with net gains and losses, including any interest or dividend income, recognized in profit or loss.

Financial assets at amortized cost

Financial assets at amortized cost are financial assets with fixed or determinable payments that are not quoted in an active market. Subsequent to initial recognition, these financial assets are recorded at amortized cost using the effective interest method, except for short-term receivables when the recognition of interest would be immaterial. Accounts receivable are assessed for evidence of impairment at each reporting date, with any impairment recognized in earnings for the period. Financial assets in this category include cash and cash equivalents and accounts receivables.

Financial assets at fair value through other comprehensive income (FVOCI)

Marketable securities, investment in subscription receipts and reclamation deposits are designated as FVOCI and recorded at fair value. Dividends are recognized as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are recognized in OCI and are never reclassified to profit or loss.

All financial assets not classified as measured at amortized cost or FVOCI are measured at fair value through profit or loss (FVPL). Derivative financial instruments that are not designated and effective as hedging instruments are classified as FVPL. Financial instruments classified as FVPL are stated at fair value with any changes in fair value recognized in earnings for the period. Financial assets in this category include derivative financial instruments that the Company acquires to manage exposure to commodity price fluctuations. These instruments are non-hedge derivative instruments.

Financial liabilities

Financial liabilities are initially recorded at fair value, net of transaction costs, and are subsequently measured at amortized cost using the effective interest method. The Company has accounted for accounts payable and accrued liabilities and long-term debt under this method.

Fair value measurement

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, by reference to 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).

(d) Exploration and evaluation

Exploration and evaluation expenditures relate to the initial search for a mineral deposit and the subsequent evaluation to determine the economic potential of the mineral deposit. The exploration and evaluation stage commences when the Company obtains the legal right or license to begin exploration. Exploration and evaluation expenditures are recognized in earnings in the period in which they are incurred.

Capitalization of development costs as mineral property, plant and equipment commences once the technical feasibility and commercial viability of the extraction of mineral reserve and resources associated with the Company's evaluation properties are established and management has made a decision to proceed with development.

(e) Inventories

Inventories are valued at the lower of cost and net realizable value. Cost is determined on a weighted average basis and includes direct labour and materials; non-capitalized stripping costs; depreciation and amortization; freight; and overhead costs. Net realizable value is determined with reference to relevant market prices, less applicable variable selling costs and estimated remaining costs of completion to bring the inventories into saleable form.

Ore stockpiles represent stockpiled ore that have not yet completed the production process, and are not yet in a saleable form. Finished goods inventories represent metals in saleable form that have not yet been sold. Materials and supplies inventories represent consumables used in the production process, as well as spare parts and other maintenance supplies that are not classified as capital items.

The quantity of recoverable metal in stockpiled ore and in the processing circuits is an estimate which is based on the tons of ore added and removed, expected grade and recovery. The quantity of recoverable metal in concentrate is an estimate using initial assay results.

(f) Property, plant and equipment

Land, buildings, plant and equipment

Land, buildings, plant and equipment are recorded at cost, including all expenditures incurred to prepare an asset for its intended use.

Repairs and maintenance costs are charged to expense as incurred, except when these repairs significantly extend the life of an asset or result in an operating improvement. In these instances, the portion of these repairs relating to the betterment is capitalized as part of plant and equipment.

Depreciation is based on the cost of the asset less residual value. Where an item of plant and equipment is comprised of major components with different useful lives, the components are accounted for as separate items and depreciated separately. Depreciation commences when an asset is available for use. Estimates of remaining useful lives and residual values are reviewed annually. Changes in estimates are accounted for prospectively.

The depreciation rates of the major asset categories are as follows:

Land | Not depreciated
Buildings | Straight-line basis over 10-25 years
Plant and equipment | Units-of-production basis
Mining equipment | Straight-line basis over 5-20 years
Light vehicles and other mobile equipment | Straight-line basis over 2-5 years
Furniture, computer and office equipment | Straight-line basis over 2-3 years

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

Mineral properties

Mineral properties consist of the cost of acquiring, permitting and developing mineral properties. Once in production, mineral properties are amortized on a units-of-production basis over the component of the ore body to which the capitalized costs relate.

Property acquisition costs arise either as an individual asset purchase or as part of a business combination, and may represent a combination of either proven and probable reserves, resources, or future exploration potential. When management has not made a determination that technical feasibility and commercial viability of extracting a mineral resource are demonstrable, the entire amount is considered property acquisition costs and not amortized. When such property moves into development, the property acquisition cost asset is transferred to mineral properties within property, plant and equipment.

Mineral property development costs include: stripping costs incurred in order to provide initial access to the ore body; stripping costs incurred during production that generate a future economic benefit by increasing the productive capacity, extending the productive life of the mine or allowing access to a mineable reserve; capitalized project development costs; and capitalized interest.

Construction in progress

Construction in progress includes the purchase price and any costs directly attributable to bringing the asset to the location and condition necessary for its intended use. Construction in progress includes advances on long-lead items. Construction in progress is not depreciated. Once the asset is complete and available for use, the costs of construction are transferred to the appropriate category of property, plant and equipment, and depreciation commences.

Capitalized interest

Interest is capitalized for qualifying assets. Qualifying assets are assets that require a substantial period of time to prepare for their intended use. Capitalization ceases when the asset is substantially complete or if construction is interrupted for an extended period. Where the funds used to finance a project form part of general borrowings, the amount capitalized is calculated using a weighted average of rates applicable to relevant general borrowings of the Company during the period.

Leased assets

The Company has adopted IFRS 16, Leases effective January 1, 2019 using the modified retrospective method. The Company assesses whether a contract is a lease or contains a lease, at the inception of a contract. The Company recognizes a right-of-use asset ("ROU asset") and a corresponding lease liability with respect to all lease arrangements in which it is the lessee, at the commencement of the lease, with the exception of short-term and low value leases, which are recognized on a straight-line basis over the lease term.

The ROU asset is initially measured based on the present value of lease payments, lease payments made at or before the commencement date, and any initial direct costs. They are subsequently measured at cost less accumulated depreciation and impairment losses. The ROU asset is depreciated over the shorter of the lease term or the useful life of the underlying asset and is subject to testing for impairment if there is an indicator of impairment.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

The lease liability is initially measured at the present value of lease payments that are not paid at the commencement date, discounted by using the rate implicit in the lease. If this rate cannot be readily determined, the Company uses its incremental borrowing rate. Lease payments include fixed payments less any lease incentives, and any variable lease payments where variability depends on an index or rate. When the lease contains an extension or purchase option that the Company considers reasonably certain to be exercised, the cost of the option is included in the lease payments.

ROU assets are included in property, plant, and equipment, (Note 15) and the lease liability is included in debt in the consolidated balance sheet (Note 18).

Impairment

The carrying amounts of the Company's non-financial assets are reviewed for impairment whenever circumstances suggest that the carrying value may not be recoverable. If such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment, if any. These assessments require the use of estimates and assumptions such as long-term commodity prices, discount rates, future capital requirements, exploration potential and operating performance.

The recoverable amount of an asset or cash generating unit (CGU) is the higher of fair value less costs of disposal and value in use. Fair value is determined as the amount that would be obtained from the sale of the asset in an arm's-length transaction between knowledgeable and willing parties. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre‐tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset. For the purpose of impairment testing, assets that cannot be tested individually are grouped together into the smallest group of assets that generates cash inflows that are largely independent of the cash flows of other assets or CGU's. If the recoverable amount of an asset or its related CGU is estimated to be less than its carrying amount, the carrying amount of the asset or CGU is reduced to its recoverable amount and the impairment loss is recognized in earnings for the period.

Where an impairment loss subsequently reverses, the carrying amount of the asset or CGU is increased to the revised estimate of its recoverable amount, but not to an amount that exceeds the carrying amount that would have been determined had no impairment loss been recognized for the asset or CGU in prior years. A reversal of an impairment loss is recognized immediately in earnings.

The carrying amount of the CGU to which goodwill has been allocated is tested annually for impairment or when there is an indication that the goodwill may be impaired. Any goodwill impairment is recognized as an expense in the profit or loss. Should there be a recovery in the value of a CGU, any impairment of goodwill previously recorded is not subsequently reversed.

(g) Income taxes

Income tax on the earnings for the periods presented comprises current and deferred tax. Income tax is recognized in earnings except to the extent that it relates to items recognized directly in equity or in other comprehensive income. Income tax is calculated using tax rates enacted or substantively enacted at the reporting date applicable to the period of expected realization or settlement.

Current tax expense is the expected tax payable on the taxable income for the year, adjusted for amendments to tax payable with regards to previous years.

Deferred tax is determined using the balance sheet liability method, providing for temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for taxation purposes. The following temporary differences are not provided for: the initial recognition of assets or liabilities acquired (not in a business combination) that affect neither accounting nor taxable profit on acquisition; and differences relating to investments in subsidiaries, associates, and joint ventures to the extent that they are not probable to reverse in the foreseeable future. The amount of deferred tax provided is based on the expected manner of realization or settlement of the carrying amount of assets and liabilities. A deferred tax asset is recognized only to the extent that it is probable that future taxable profits will be available against which the asset can be utilized. Deferred tax assets are reviewed at each reporting date and are reduced to the extent it is no longer probable that the related tax benefit will be realized.

(h) Share-based compensation

The fair-value method is used for the Company's share-based payment transactions. Under this method, the cost of share options and equity-settled performance share units is recorded based on their estimated fair value at the grant date, including an estimate of the forfeiture rate. The fair value of the share options and performance share units is expensed on a graded amortization basis over the vesting period of the awards, with a corresponding increase in equity.

Share-based compensation expense relating to cash-settled awards, including deferred share units, is recognized based on the quoted market value of the Company's common shares on the date of grant. The related liability is re-measured to fair value each reporting period to reflect changes in the market value of the Company's common shares, with changes in fair value recorded in net profit (loss).

(i) Provisions

Environmental rehabilitation

The Company records the present value of estimated costs of legal and constructive obligations required to retire an asset in the period in which the obligation occurs. Environmental rehabilitation activities include facility decommissioning and dismantling; removal and treatment of waste materials, including water treatment; site and land rehabilitation, including compliance with and monitoring of environmental regulations; and related costs required to perform this work and/or operate equipment designed to reduce or eliminate environmental effects. The provision for environmental rehabilitation ("PER") is adjusted each period for new disturbances, and changes in regulatory requirements, the estimated amount of future cash flows required to discharge the liability, the timing of such cash flows and the pre-tax discount rate specific to the liability. The unwinding of the discount is recognized in earnings as a finance cost.

When a PER is initially recognized, the corresponding cost is capitalized by increasing the carrying amount of the related asset, and is amortized to earnings on a unit-of-production basis. Costs are only capitalized to the extent that the amount meets the definition of an asset and represents future economic benefits to the operation.

Significant estimates and assumptions are made in determining the provision for environmental rehabilitation as there are a number of factors that will affect the ultimate liability. These factors include estimation of the extent and cost of rehabilitation activities; timing of future cash flows, changes in discount rates; inflation rate; and regulatory requirements.

Other provisions

Other provisions are recognized when the Company has a present obligation (legal or constructive) that has arisen as a result of a past event and it is probable that a future outflow of resources will be required to settle the obligation, provided that a reliable estimate can be made of the amount of the obligation. Where the effect is material, the provision is discounted using a pre-tax rate that reflects current market assessments of the time value of money and the risk specific to the obligation. The accretion expense is included in finance expense.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

(j) Finance income and expenses

Finance income comprises interest income on funds invested, gains on the disposal of marketable securities, and changes in the fair value of derivatives included in cash and equivalents and marketable securities. Interest income is recognized as it accrues in earnings, using the effective interest method. Finance expenses comprise interest expense on borrowings, unwinding of the discount on provisions, the finance component on deferred revenue, losses on the disposal of marketable securities, changes in the fair value of derivatives included in cash and cash equivalents and marketable securities, and impairment losses recognized on financial assets. Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are recognized in earnings using the effective interest method.

(k) Earnings (loss) per share

The Company presents basic and diluted earnings (loss) per share data for its common shares, calculated by dividing the earnings (loss) attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the period. Diluted earnings per share is determined by adjusting the earnings attributable to common shareholders and the weighted average number of common shares outstanding for the effects of all dilutive potential common shares, which comprise warrants and share options granted. There is no dilution impact when the Company incurs a loss.

(l) Interests in joint arrangements

IFRS defines a joint arrangement as one over which two or more parties have joint control, which is the contractually agreed sharing of control over an arrangement. This exists only when the decisions about the relevant activities (being those that significantly affect the returns of the arrangement) require the unanimous consent of the parties sharing control.

A joint operation is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the assets and obligations for the liabilities, relating to the arrangement. In relation to its interests in joint operations, the Company recognizes its:

- Assets, including its share of any assets held jointly;
- Liabilities, including its share of any liabilities incurred jointly;
- Revenue from the sale of its share of the output arising from the joint operation; and
- Expenses, including its share of any expenses incurred jointly.

2.5 New standards and interpretations not yet adopted

Several new standards, and amendments to standards and interpretations, are not yet effective for the year ended December 31, 2020, and have not been applied in preparing these consolidated financial statements. None are currently considered by the Company to be significant or likely to have a material impact on future financial statements.

3. INTEREST IN GIBRALTAR JOINT VENTURE

On March 31, 2010, the Company entered into an agreement with Cariboo Copper Corp. (Cariboo) whereby the Company contributed certain assets and liabilities of the Gibraltar mine, operating in British Columbia, into an unincorporated joint venture to acquire a 75% interest in the joint venture. Cariboo contributed $186,800 to purchase the remaining 25% interest.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

The assets and liabilities contributed by the Company to the joint venture were mineral property interests, plant and equipment, inventories, prepaid expenses, reclamation deposits, capital lease obligations, and site closure and reclamation obligations. Certain key strategic, operating, investing and financing policies of the joint venture require unanimous approval such that neither venturer is in a position to exercise unilateral control over the joint venture. The Company continues to be the operator of the Gibraltar mine.

The Company has joint control over the joint arrangement and as such consolidates its 75% portion of all the joint venture's assets, liabilities, income and expenses.

Restricted cash |  | 1,273 |  |  | 1,300 |
|  | 5,298 |  |  | 6,783 |

The Company holds strategic investments in publicly-traded and privately owned mineral exploration and development companies, including marketable securities and subscription receipts. Marketable securities and the investment in subscription receipts are accounted for at fair value through other comprehensive income (FVOCI).

During the year ended December 31, 2020, the Company received net proceeds of $7,270 from the sale of marketable securitites of a publicly traded company and the resulting gain is recognized in other comprehensive income.

The subscription receipts relate to an investment in a privately held company with two directors in common with Taseko and are to be convertible into units comprised of shares, or shares and warrants. The fair value of the investment in subscription receipts is based on public market information of comparable companies.

In November 2019, the Company restructured its reclamation funding within the Gibraltar joint venture which resulted in $6,200 of net cash becoming unrestricted and $30,000 in funds being distributed out of reclamation deposits to the Company. Gibraltar issued to the Province of British Columbia a letter of credit in the amount of $50,000 as security for current reclamation obligations for the Gibraltar mine. The $50,000 letter of credit issued by a Canadian chartered bank is collateralized by a surety bond in the amount of $37,500 for the Company's share and $12,500 for Cariboo's share of the letter of credit.

For the Florence Copper project, the Company has provided surety bonds totaling $12,489 to the federal and state regulators. The Company has provided cash collateral of $2,103 to the surety bond provider which is classified as reclamation deposits.

14. YELLOWHEAD ACQUISITION

On February 15, 2019, the Company closed an agreement to acquire all of the outstanding common shares of Yellowhead Mining Inc. ("Yellowhead") that it did not already own, in exchange for approximately 17.3 million Taseko common shares.

The total purchase consideration was calculated as follows:

Fair value of common shares issued (17,300,385 shares at $0.73 per share) |  | 12,629 |
Fair value of previously held investment in Yellowhead |  | 3,365 |
Acquisition related legal and other costs |  | 272 |
|  | 16,266 |

Prior to the acquisition, the Company held a 21% equity interest in Yellowhead. This investment was previously accounted for as a FVOCI financial asset and was remeasured to its fair value of $3,365 based on the trading price of its common shares on the acquisition date.

The acquisition of Yellowhead has been accounted for as an asset acquisition and accordingly, the purchase consideration has been allocated to the assets acquired and liabilities assumed, based upon their estimated fair values at the date of acquisition.

The following sets forth the allocation of the purchase price:

Cash and cash equivalents |  | 187 |
Accounts receivable and other assets |  | 14 |
Reclamation deposits |  | 85 |
Property, plant and equipment |  | 16,240 |
Accounts payable and other liabilities |  | (260 | )
|  | 16,266 |

Yellowhead had cumulative tax pools of approximately $57,000 comprised of non-capital losses and resource deductions at the date of acquisition. A full valuation allowance was provided against the deferred tax assets arising from these tax pools due to uncertainty over the timing of their potential utilization at the time of acquisition.

Prior to January 2020, Yellowhead was in the evaluation phase and project related expenditures were expensed. In January 2020, the Company announced the results of its own technical studies on Yellowhead and filed a new NI 43-101 technical report and the project entered the development phase for accounting purposes. All costs since January 1, 2020 are being captitalized as mineral property, plant and equipment (Note 15).

(a) Senior secured notes

In June 2017, the Company completed an offering of US$250,000 aggregate principal amount of senior secured notes (the "2022 Notes"). The Notes mature on June 15, 2022 and bear interest at an annual rate of 8.750%, payable semi-annually on June 15 and December 15.

The 2022 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 relating to the Gibraltar Mine. The 2022 Notes are guaranteed by each of Taseko's existing and future restricted subsidiaries, other than Yellowhead. The Company is able to incur limited amounts of additional secured and unsecured debt under certain conditions as defined in the indenture. The Company is also subject to certain restrictions on asset sales, issuance of preferred stock, dividends and other restricted payments. However, there are no maintenance covenants with respect to the Company's financial performance.

On February 10, 2021, the Company announced that it had closed an offering of US$400 million aggregate principal amount of Senior Secured Notes due 2026 (the "2026 Senior Secured Notes"). Interest on the 2026 Senior Secured Notes will accrue at an annual rate of 7.0% payable semi-annually. Taseko intends to use the majority of the net proceeds from this offering to redeem all the 2022 Notes, including the call premium of 102.188% and accrued interest (Note 27).

(b) Lease liabilities

Lease liabilities include the Company's outstanding lease liabilities under IFRS 16. At December 31, 2020, the net carrying amount of leased assets was $32,449 (2019: $37,254).

The lease liabilities have monthly repayment terms ranging between 8 and 70 months and with interest rates between 4.2% and 6.3%.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

(c) Secured equipment loans

The equipment loans are secured by existing mining equipment at the Gibraltar Mine and commenced between June, 2018 and August, 2019 with monthly repayment terms ranging between 48 and 60 months and with interest rates ranging between 5.2% to 6.4%.

In May 2019, Gibraltar entered into an equipment loan with the Company's share of proceeds being $13,875 and in August 2019, Gibraltar entered into an equipment loan with the Company's share of proceeds being $7,977.

(d) Lease related obligations

Lease related obligations relate to a lease arising under a sale leaseback transaction on certain items of equipment at the Gibraltar mine. The lease commenced in June 2019 and has a term of 54 months. At the end of the lease term, the Company has an option to renew the term, an option to purchase the equipment at fair market value or option to return the equipment. The lease contains a fixed price early buy-out option exercisable at the end of 48 months.

19. DEFERRED REVENUE

On March 3, 2017, the Company entered into a silver stream purchase and sale agreement with Osisko Gold Royalties Ltd. ("Osisko"), whereby the Company received an upfront cash deposit payment of US$33 million for the sale of an equivalent amount of its 75% share of Gibraltar payable silver production until 5.9 million ounces of silver have been delivered to Osisko. 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 to Osisko. The Company receives cash payments of US$2.75 per ounce for all silver deliveries made under the agreement.

On April 24, 2020, Taseko entered into an amendment to its silver stream with Osisko and received $8,510 in exchange for reducing the delivery price of silver from US$2.75 per ounce to nil. The amendment is accounted for as a contract modification under IFRS 15 Revenue from Contracts with Customers. The funds received are available for general working capital purposes.

The silver sale agreement has a minimum term of 50 years and automatically renews for successive 10-year periods as long as Gibraltar mining operations are active. If the initial deposit is not fully reduced through silver deliveries at current market prices at time of the deliveries, a cash payment for the remaining amount will be due to Osisko at the expiry date of the agreement. The Company's obligations under the agreement are secured by a pledge of Taseko's 75% interest in the Gibraltar joint venture.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

In connection with the silver stream transaction, the Company issued share purchase warrants to Osisko, which expired unexercised on April 1, 2020.

The Company recorded the deposits from Osisko as deferred revenue and recognizes amounts in revenue as silver is delivered. The amortization of deferred revenue is calculated on a per unit basis using the estimated total number of silver ounces expected to be delivered to Osisko over the life of the Gibraltar mine. The current portion of deferred revenue is an estimate based on deliveries anticipated over the next twelve months.

The following table summarizes changes in the Osisko deferred revenue:

Balance at January 1, 2019 |  | 43,274 |
Finance expense (Note 9) |  | 4,154 |
Amortization of deferred revenue |  | (3,437 | )

The PER represents the present value of estimated costs of legal and constructive obligations required to retire an asset, including decommissioning and other site restoration activities. The majority of these expenditures occur after the end of the life of the related operation. For the Gibraltar mine, it is anticipated that these costs will be incurred over a period of at least 100 years beyond the end of the current mine life based on known reserves. The change in the PER during 2020 is primarily due to changes in the risk-free discount rates applied in determining the obligation.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

As at December 31, 2020, the PER was calculated on a present value basis for closure costs to be incurred in the first 30 years using a nominal risk-free discount rate of 1.63% (2019 - 1.93%) based on the 30 year overnight index swap (OIS) rate. For discounting annual closure cashflows beyond 30 years, a risk free yield curve was extrapolated from the implied OIS swap rate for liquid, investment grade corporate bonds with durations between 50 to 100 years. A nominal risk free rate of up to 2.86% was utilized in 2020 (2019 - 3.05%) for discounting closure costs up to 100 years from the estimated date of site closure for Gibraltar based on current reserves. An inflation rate of 1.49% (2019 - 1.42%) was applied in deriving nominal cash flow estimates

PER estimates are reviewed regularly and there have been adjustments to the amount and timing of cash flows as a result of updated information. Assumptions are based on the current economic environment, but actual rehabilitation costs will ultimately depend upon future market prices for the necessary decommissioning work required, which will reflect market conditions at the relevant time. Furthermore, the timing of rehabilitation will depend on when the mine ceases production which, in turn, will depend on future mineral reserves, metal prices, operating conditions and many other factors which are inherently uncertain.

The Company has provided letters of credit, surety bonds and deposits held in trust to the regulatory authorities for its share of reclamation obligations (Note 13). Security for reclamation obligations is returned once the site is reclaimed to a satisfactory level and there are no ongoing monitoring or maintenance requirements.

22. SHARE-BASED COMPENSATION

(a) Share Options

The Company has an equity settled share option plan approved by the shareholders that allows it to grant options to directors, officers, employees and other service providers. Under the plan, a maximum of 9.5% of the Company's outstanding common shares may be granted. The maximum allowable number of outstanding options to independent directors as a group at any time is 1% of the Company's outstanding common shares. The exercise price of an option is set at the time of grant using the five-day volume weighted average price of the common shares. Options are exercisable for a maximum of five years from the effective date of grant under the plan. Vesting conditions of options are at the discretion of the Board of Directors at the time the options are granted.

|  | Options (thousands) |  |  | Average price |

(b) Deferred Share Units and Performance Share Units

The Company has adopted a Deferred Share Unit ("DSU") Plan (the "DSU Plan") that provides for an annual grant of DSUs to each non-employee director of the Company, or an equivalent cash payment in lieu thereof, which participants have agreed would in the first instance be used to assist in complying with the Company's share ownership guidelines. DSUs vest immediately upon grant and are paid out in cash when a participant ceases to be a director of the Company. A long-term financial liability of $3,525 has been recorded at December 31, 2020 (2019 - $1,483), representing the fair value of the liability, which is based on the Company's stock price at the reporting period date.

The Company has established a Performance Share Unit ("PSU") Plan (the "PSU Plan") whereby PSUs are issued to executives as long-term incentive compensation. PSUs issued under the Plan entitle the holder to a cash or equity payment (as determined by the Board of Directors), at the end of a three-year performance period equal to the number of PSU's granted, adjusted for a performance factor and multiplied by the quoted market value of a Taseko common share on the completion of the performance period. The performance factor can range from 0% to 250% and is determined by comparing the Company's total shareholder return to those achieved by a peer group of companies.

|  | DSUs (thousands) |  |  | PSUs (thousands) |
Outstanding at January 1, 2019 |  | 2,328 |  |  | 1,210 |
Granted |  | 682 |  |  | 875 |

Outstanding at December 31, 2020 |  | 2,123 |  |  | 2,100 |

During the year ended December 31, 2020, 572,000 DSUs were issued to directors (2019 - 682,000) and 825,000 PSUs to senior executives (2019 - 875,000). The fair value of DSUs and PSUs granted was $899 (2019 - $1,696), with a weighted average fair value at the grant date of $0.72 per unit for the DSUs (2019 - $0.78 per unit) and $0.59 per unit for the PSUs (2019 - $1.33 per unit).

25. FINANCIAL RISK MANAGEMENT

(a) Overview

In the normal course of business, the Company is inherently exposed to market, liquidity and credit risk through its use of financial instruments. The timeframe and manner in which the Company manages these risks varies based upon management's assessment of the risk and available alternatives for mitigating risk. The Board approves and monitors risk management processes, including treasury policies, counterparty limits, controlling and reporting structures.

(b) Market risk

Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. Market prices comprise three types of risk: commodity price risk; interest rate risk; and currency risk. Financial instruments affected by market risk include: cash and equivalents; accounts receivable; marketable securities; subscription receipts; reclamation deposits; accounts payable and accrued liabilities; debt and derivatives.

The objective of market risk management is to manage and control market risk exposures within acceptable parameters, while optimizing the return. The Company buys copper put options in order to reduce commodity price risk. The derivative instruments employed by the Company are considered to be economic hedges but are not designated as hedges for accounting purposes.

Commodity price risk

The Company is exposed to the risk of fluctuations in prevailing market commodity prices on the metals it produces. The Company enters into copper put option contracts to reduce the risk of short-term copper price volatility. The amount and duration of the hedge position is based on an assessment of business-specific risk elements combined with the copper pricing outlook. Copper put option contracts are typically extended adding incremental quarters at established put strike prices to provide the necessary price protection.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

Provisional pricing mechanisms embedded within the Company's sales arrangements have the character of a commodity derivative and are carried at fair value as part of accounts receivable. The table below summarizes the impact on revenue and receivables for changes in commodity prices on the provisionally invoiced sales volumes.

|  | As at December 31, |
|  | 2020 |  |  | 2019 |
Copper increase/decrease by US$0.37/lb. (2019: US$0.28/lb.)1 |  | 9,542 |  |  | 7,992 |

1The analysis is based on the assumption that the year-end copper price increases/decreases 10 percent with all other variables held constant. At December 31, 2020, 20 million (2019: 22 million) pounds of copper in concentrate were exposed to copper price movements. The closing exchange rate at December 31, 2020 of CAD/USD 1.27 (2019: 1.30) was used in the analysis.

The sensitivities in the above tables have been determined with foreign currency exchange rates held constant. The relationship between commodity prices and foreign currencies is complex and movements in foreign exchange can impact commodity prices. The sensitivities should therefore be used with care.

Interest rate risk

The Company is exposed to interest rate risk on its outstanding debt and investments, including cash and cash equivalents, from the possibility that changes in market interest rates will affect future cash flows or the fair value of fixed-rate interest-bearing financial instruments.

The table below summarizes the impact on earnings after tax and equity for a change of 100 basis points in interest rates at the reporting date. This analysis assumes that all other variables, in particular foreign currency rates, remain constant. This assumes that the change in interest rates is effective from the beginning of the financial year and balances are constant over the year. However, interest rates and balances of the Company may not remain constant in the coming financial year and therefore such sensitivity analysis should be used with care.

|  | Years ended December 31, |
|  | 2020 |  |  | 2019 |
Fair value sensitivity for fixed-rate instruments |  |  |  |  |  |
Senior secured notes |  | (1,696 | ) |  | (1,768 | )
Lease liabilities |  | (61 | ) |  | (149 | )
Lease related obligations |  | (83 | ) |  | (44 | )
Secured equipment loans |  | (142 | ) |  | (134 | )
|  | (1,982 | ) |  | (2,095 | )
Cash flow sensitivity for variable-rate instruments |  |  |  |  |  |
Cash and equivalents |  | 617 |  |  | 386 |

Currency risk

The Canadian dollar is the functional currency of the Company and, as a result, currency exposure arises from transactions and balances in currencies other than the Canadian dollar, primarily the US dollar. The Company's potential currency exposures comprise translational exposure in respect of non-functional currency monetary items, and transactional exposure in respect of non-functional currency revenues and expenditures.

The following table demonstrates the sensitivity to a 10% strengthening in the CAD against the USD. With all other variables held constant, the Company's shareholders equity and earnings after tax would both increase/(decrease) due to changes in the carrying value of monetary assets and liabilities. A weakening in the CAD against the USD would have had the equal but opposite effect to the amounts shown below.

TASEKO MINES LIMITED Notes to Consolidated Financial Statements (Cdn$ in thousands)

|  | Years ended December 31, |
|  | 2020 |  |  | 2019 |
Cash and equivalents |  | (6,213 | ) |  | (2,803 | )
Accounts receivable |  | (412 | ) |  | (824 | )
Accounts payable and accrued liabilities |  | 563 |  |  | 587 |
Senior secured notes |  | 23,321 |  |  | 23,790 |
Equipment loans |  | 414 |  |  | 527 |
Lease liabilities |  | 40 |  |  | 62 |

The Company's financial asset and liability profile may not remain constant and, therefore, these sensitivities should be used with care.

(c) Liquidity risk

Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they become due. The Company manages liquidity risk by holding sufficient cash and equivalents and scheduling long-term obligations based on estimated cash inflows. There were no defaults on loans payable during the year.

(d) Credit risk

Credit risk is the risk of potential loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company is exposed to credit risk from its receivables, marketable securities and investments, and derivatives. In general, the Company manages its credit exposure by transacting only with reputable counterparties. The Company monitors the financial condition of its customers and counterparties to contracts. The Company deals with a limited number of counterparties for its metal sales. The Company had two significant customers in 2020 that represented 88% of gross copper concentrate revenues (2019: two customers accounted for 87% of gross copper concentrate revenues). The trade receivable balance at December 31, 2020 is comprised of three customers (2019: three customers). There are no impairments recognized on the trade receivables.

(e) Fair values of financial instruments

The fair values of the senior secured notes is $324,029 and the carrying value is $313,965 at December 31, 2020. The fair value of all other financial assets and liabilities approximates their carrying value.

The Company uses the fair value hierarchy described in Note 2.4(c) for determining the fair value of instruments that are measured at fair value.

There have been no transfers between fair value levels during the reporting period. The carrying value of cash and equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value as at December 31, 2020.

The fair value of the senior secured notes, a Level 1 instrument, is determined based upon publicly available information.

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. At December 31, 2020, the Company had settlement receivables of $4,676 (2019 - $9,006).

The subscription receipts, a Level 3 instrument, are valued based on a management estimate. As the subscription receipts are an investment in a private exploration and development company, there are no observable market data inputs. At December 31, 2020 the determination of the estimated fair value of the investment includes comparison to the market capitalization of comparable public companies.

(f) Capital management

The Company's primary objective when managing capital is to ensure that the Company is able to continue its operations and that it has sufficient ability to satisfy its capital obligations and ongoing operational expenses, as well as to have sufficient liquidity available to fund suitable business opportunities as they arise.

The Company considers the components of shareholders' equity, as well as its cash and equivalents, credit facilities and debt as capital. The Company manages its capital structure and makes adjustments to it in light of changes in economic conditions and the risk characteristics of the underlying assets. In order to maintain or adjust the capital structure, the Company may issue or buy back equity, issue, buy back or repay debt, sell assets, or return capital to shareholders.

In order to facilitate the management of its capital requirements, the Company prepares annual operating budgets that are approved by the Board of Directors. Management also actively monitors the covenants on its long-term debt to ensure compliance. The Company's investment policy is to invest cash in highly liquid interest-bearing investments that are readily convertible to known amounts of cash. There were no changes to the Company's approach to capital management during the year ended December 31, 2020.
