Management's Discussion and Analysis

Operations Analysis

First Quarter Review

In the first quarter, mining activity at Gibraltar was focused on waste stripping for a new pushback in the Connector pit, which resulted in a higher than normal strip ratio and lower mined ore in the period. Lower grade stockpiled ore was the primary source of mill feed, resulting in lower copper production compared to recent quarters.

Gibraltar produced 20.0 million pounds of copper in the first quarter and copper head grade was 0.19%, well below average reserve grade. Copper recovery was 68% and was notably impacted by oxidation in the stockpiled ore which mainly originated from the upper benches of the Connector pit. Mill throughput was 7.9 million tons in the quarter, above nameplate capacity due to the lower work index ore in the Connector pit.

A total of 23.2 million tons were mined in the first quarter comparable to recent quarters. The average strip ratio was 4.6, as a total of 4.2 million tons of ore were mined. This includes 2.2 million tons of oxide ore that was added to the heap leach pads as plans for restart of the solvent extraction and electrowinning ("SX/EW") plant continue in Q2 2025.

Capitalized stripping totaling $38.1 million was higher in the first quarter attributed to greater mining of waste tons above the average strip ratio for the Connector pit. Total site costs* including capitalized stripping was $107.0 million in the quarter consistent with the comparative prior year quarter. Decreased consumption of mining inputs such as diesel and explosives due to processing of stockpile material as well as lower diesel prices were offset by higher milling costs.

Molybdenum production was 336 thousand pounds in the first quarter compared to 247 thousand pounds in the comparative prior year quarter. Higher molybdenum grades, on average, are expected in Connector pit ore. Grades will improve as stockpile ore feed decreases. At an average molybdenum price of US$20.53 per pound for the quarter, molybdenum contributed a meaningful by-product credit of US$0.33 per pound of copper produced.

Off-property costs were US$0.18 per pound of copper produced. These lower costs reflect Gibraltar's 2025 offtake agreements with very favorable treatment and refining charges ("TCRC"). On a blended basis, TCRCs are effectively nil for this year.

Total operating cost (C1)* was US$2.26 per pound of copper produced in the first quarter compared to US$2.46 in the comparative prior year quarter. Higher capitalized stripping costs, improved molybdenum by-product credits, and lower off property costs all contributed to driving down total operating cost (C1), partially offset by the effect of lower copper production as shown in the bridge graph below:

Management's Discussion and Analysis

Gibraltar Outlook

Mining activities are now focused in the Connector pit, which will be the source of mill feed in 2025 and the years ahead. Copper production in the first quarter was approximately 10% below expectations, due to low recoveries from oxidized ore. In addition, mining rates in the upper benches of Connector pit have been behind plan due to challenging ground conditions resulting in lower equipment productivities. As a result, access to higher quality ore has been delayed from the second quarter to the third quarter, and annual copper production for 2025 is expected to be approximately 10 million pounds below the previous guidance of 120 to 130 million pounds. Significant increases in head grades and recoveries are expected in the second half of 2025 and continuing into 2026.

Increased mill availability and higher throughput is also expected this year, as major maintenance projects were completed in both mills last year. Refurbishment of the Gibraltar SX/EW plant, which has been idle since 2015, is nearing completion, with first cathode production expected in the second quarter, supplementing Gibraltar copper concentrate production.

Molybdenum production is forecast to increase in 2025 as molybdenum grades are expected to be notably higher as more Connector pit ore is processed, also weighted to the second half of the year.

The Company has offtake agreements covering Gibraltar concentrate production in 2025 and 2026, which contain significantly lower, and in certain cases negative (premium), TCRC rates reflecting the tightening copper smelting market. In 2024, TCRCs accounted for approximately US$0.09 per pound of off-property costs, and, with the new offtake agreements, the Company expects average TCRCs to reduce to nil in 2025 and 2026.

Potential US import tariffs are not expected to have a material impact on sales at Gibraltar as the mine produces copper and molybdenum concentrates that are sold to international metal traders and delivered to Asian markets. Offtake agreements are in place for substantially all of Gibraltar's copper concentrate production in 2025 and 2026, and no changes to these sales channels are expected during this period.

The Company has a prudent hedging program in place to protect a minimum copper price and Gibraltar cash flow during the Florence Copper construction period. Currently, the Company has copper collar contracts in place that secure a minimum copper price of US$4.00 per pound for 81 million pounds of copper production for the remainder of 2025 (refer to "Financial Condition Review—Hedging Strategy" for details).

Management's Discussion and Analysis

Florence Copper

The Company has all key permits in place for the commercial production facility at Florence and construction of the Florence Copper commercial production facility continues to advance on schedule. Approximately 670,000 project hours have been worked with no reportable injuries or environmental incidents. The Company has a fixed-price contract with the general contractor for construction of the SX/EW plant and associated surface infrastructure.

A total of 80 production wells out of a total of 90 new wells to be drilled during the construction phase have been completed as of March 31, 2025. Process ponds and surface water runoff pond construction are complete, and installation of high-density polyethylene piping in the main pipeline corridor continued. Mechanical and piping installations throughout the SX/EW plant and electrical work continue to advance. Assembly of the modular office and dry buildings were also completed, and work on the exterior finishing has started.

Site activities are focused on hiring additional personnel and other initiatives to support operational readiness and the ramp up of production.

Florence Copper capital spend (US$ in thousands) Three months ended March 31, 2025
Commercial facility construction costs 51,364
Site and PTF operations 6,069
Total Florence Copper capital spend 57,433

Florence Copper commercial facility construction costs were US$51.4 million in the first quarter and, since the beginning of construction, US$206.3 million has been incurred on the Florence Copper commercial facility as of March 31, 2025.

In January 2025, the Company received its final US$10 million instalment from its US$50 million copper stream with Mitsui & Co. (U.S.A.) Inc. ("Mitsui"). The remaining Florence Copper commercial production facility construction costs are expected to be funded from the Company's available liquidity and cash flows from Gibraltar.

The Company has a technical report titled "NI 43-101 Technical Report Florence Copper Project, Pinal County, Arizona" dated March 30, 2023 (the "Florence 2023 Technical Report") on SEDAR+. The Florence 2023 Technical Report was prepared in accordance with National Instrument 43-101 ("NI 43-101") and incorporated the results of test work from the production test facility ("PTF") as well as updated capital and operating costs (Q3 2022 basis) for the commercial production facility.

Project highlights based on the Florence 2023 Technical Report are detailed below:

  • Net present value of US$930 million (at US$3.75 copper price, 8% after-tax discount rate);
  • After-tax internal rate of return of 47%;
  • Payback period of 2.6 years;
  • Operating costs (C1) of US$1.11 per pound of copper produced;
  • Annual production capacity of 85 million pounds of LME grade A copper cathode;
  • Mine life of 22 years;
  • Total life of mine production of 1.5 billion pounds of copper; and
  • Initial capital cost of US$232 million (Q3 2022 basis).

TASEKO MINES LIMITED

Management's Discussion and Analysis

Based on the Florence 2023 Technical Report, the estimated construction costs for the Florence Copper commercial production facility were US$232 million and management expects that total construction costs will be within a range of 10% to 15% higher than this estimate. Florence Copper remains on track for first copper cathode production in Q4 2025.

Long-term Growth Strategy

Taseko's strategy has been to grow the company by acquiring and developing a pipeline of projects focused on copper in North America. We continue to believe this will generate long-term returns for shareholders. Our other development projects are located in BC, Canada.

Yellowhead copper project

The Yellowhead copper project ("Yellowhead") is expected to produce 4.4 billion pounds of copper over a 25-year mine life. During the first 5 years of operation, Yellowhead is expected to produce an average of 200 million pounds of copper per year. Yellowhead also contains valuable precious metal by-products with 440,000 ounces of gold production and 19 million ounces of silver production over the life of mine. The Yellowhead project is subject of technical report published in January 2020.

Taseko plans to publish an updated technical report on Yellowhead in 2025 using updated long-term metal price assumptions, updated project costing, and incorporating the new Canadian tax credits available for copper mine development.

The Company is ready to enter the environmental assessment ("EA") process and plans to submit an Initial Project Description to formally commence the EA process with regulators in Q2 2025. The Company is focusing discussions with regulators on developing a streamlined permitting process. Taseko also opened a Yellowhead project office in 2024 to support ongoing engagement with local communities including First Nations.

New Prosperity copper-gold project

In late 2019, the T$ilhqot'in Nation, as represented by the T$ilhqot'in National Government, and Taseko entered into a confidential dialogue, with the involvement of the Province of BC, seeking a long-term resolution to the conflict regarding Taseko's proposed copper-gold mine previously known as New Prosperity, acknowledging Taseko's commercial interests and the T$ilhqot'in Nation's opposition to the project.

This dialogue has been supported by the parties' agreement, beginning December 2019, to a series of standstill agreements on certain outstanding litigation and regulatory matters relating to Taseko's tenures and the area in the vicinity of Težtan Biny (Fish Lake).

This dialogue process has made meaningful progress in recent months and is close to completion. The T$ilhqot'in Nation and Taseko acknowledge the constructive nature of discussions, and the opportunity to conclude a long-term and mutually acceptable resolution of the conflict that also makes an important contribution to the goals of reconciliation in Canada.

Canadian Dollar/US Dollar Exchange

1 Commodity prices in US dollars per pound.
2 Sources: London Metal Exchange for copper prices, Platts Metals for molybdenum prices, Bank of Canada for Canadian dollar/US dollar exchange rates.

Copper prices are currently around US$4.17 per pound compared to US$4.39 per pound at March 31, 2025 and the first quarter average copper price of US$4.24 per pound. Since the beginning of April, copper prices have experienced significant volatility influenced by trade uncertainty and the threat of an escalating global trade war, particularly between China and the US. China produces approximately 50% of the global refined copper and the US imports approximately 50% of its copper. The US copper market had seen significant stockpiling during the beginning of the year, with a significant premium on the COMEX price compared to the LME price, in response to threatened US tariffs on copper imports.

Recent US import tariffs are not expected to have a material impact on sales at Gibraltar as the mine produces copper and molybdenum concentrates that are sold to international metal traders and delivered to Asian markets. Offtake agreements are in place for substantially all of Gibraltar's copper concentrate production in 2025 and 2026, and no changes to these sales channels are expected during this period. Cathode produced by Gibraltar's SX/EW plant will generally be shipped overseas if a tariff between US and Canada is prohibitive. The Company does not expect any material impact on Gibraltar operating costs as a result of the new tariffs. Production at Florence is expected to remain in the US for domestic consumption.

Longer-term demand for copper is expected to remain strong driven by electrification, renewable energy transition, artificial intelligence and overall industrial activity while tight supply conditions are expected to continue due to few available sources of new primary copper supply. These factors continue to provide unprecedented catalysts and support a higher copper price in the longer term as new mine supply lags behind growth in copper demand.

Smelter treatment and refining charges remain historically low, including spot rates at negative (premium) rates, driven by an increase in global copper smelting capacity and disruptions in the supply of copper concentrates. Potential shortages of copper metal could continue, which could lead to higher copper prices further into 2025.


TASEKO MINES LIMITED

Management's Discussion and Analysis

Approximately 8% of the Company's revenue is made up of molybdenum sales and Connector pit ore is expected to provide higher molybdenum grades in the coming years. Molybdenum prices are currently around US$20.10 per pound compared to US$19.95 per pound at March 31, 2025 and the first quarter average molybdenum price of US$20.53 per pound. The Company's sales agreements specify molybdenum pricing based on published Platts Metals reports.

The Company's sales contracts are priced in US dollars while a majority of Gibraltar's costs are Canadian dollar denominated, and, therefore, fluctuations in the Canadian dollar/US dollar exchange rate can have a significant effect on the Company's financial results.

Adjusted net (loss) income (6,943) 7,728 (14,671)

1 The $15.0 million gain on acquisition of control of Gibraltar in Q1 2024 relates to the measurement at fair value of Taseko's 87.5% interest in Gibraltar finished copper concentrate inventory held at the date of acquisition of control of Gibraltar (March 25, 2024) as a result of the Company's acquisition of Cariboo. These gains have been eliminated from Adjusted net income (loss) in the period of the acquisition transaction and added back in the period the inventory was sold.
2 Q1 2024 cost of sales included $13.4 million of fair value adjustments to Gibraltar finished copper concentrate inventory held at the date of acquisition of Cariboo that was subsequently sold and realized between March 26 and March 31, 2024. This realized portion of the gain has been included in Adjusted net (loss) income.

Adjusted net loss was $6.9 million ($0.02 loss per share) in the first quarter compared to Adjusted net income of $7.7 million ($0.03 earnings per share) in the comparative prior year quarter. The decrease in Adjusted earnings of $14.7 million was primarily due to lower sales volumes and production from the processing of lower quality stockpile material as Gibraltar engages in a pushback in the Connector pit to access the next ore zone. The decrease in copper production and sales was partially offset by a stronger copper price environment and a stronger US dollar compared to the comparative prior year quarter.


TASEKO MINES LIMITED

Management's Discussion and Analysis

Cost of sales in the first quarter was consistent with the comparative prior year quarter on a total dollar basis but reflects the higher cost of stockpile material on a per pound basis due to lower sales volumes in the quarter. Mining costs generally decreased due to shorter haul distances in Connector and lower diesel prices as ore release was more focused in the Gibraltar pit in the first part of the prior year but were offset by increased milling costs arising from higher throughput.

Net loss was $28.6 million ($0.09 loss per share) in the first quarter after factoring in unrealized losses on derivatives primarily due to the increasing copper price trend in the quarter and its effect on the fair value of outstanding copper hedges covering production for the remainder of 2025. Net income was $18.9 million ($0.07 earnings per share) in the comparative prior year quarter which benefited from gains recorded on the acquisition of Cariboo from Dowa and Furukawa.

No adjustments were made to Adjusted net (loss) income for price adjustments on settlement during the period.

1 Q1 2024 results reflect the Company's 87.5% effective interest in Gibraltar for the period from January 1 to March 24, 2024 and 100% effective interest for the period from March 25 to March 31, 2024.
2 Sales of copper in concentrate includes a net smelter payable deduction of approximately 3.5% to derive net payable pounds of copper sold.

Copper revenues were $127.7 million in the first quarter compared to $143.9 million in the comparative prior year quarter. Copper revenues decreased overall by $16.2 million due to 6.5 million fewer pounds being sold resulting in a negative volume variance of $34.4 million, partially offset by a favorable price variance of $10.3 million due to higher realized copper prices of US$0.35 per pound in the current quarter and a favorable foreign exchange variance of $7.9 million due to the strength of the US dollar against the Canadian dollar in the quarter.


TASEKO MINES LIMITED

Management's Discussion and Analysis

Molybdenum revenues were $9.7 million in the first quarter compared to $6.6 million in the comparative prior year quarter. The increase in molybdenum revenues of $3.0 million was primarily driven by increased sales volume and the impact of Taseko's increased effective interest in Gibraltar.

The Company also benefitted from payable gold for the first time as one of its concentrate offtake agreements paid for gold contained in the Gibraltar concentrate.

Treatment and refining costs decreased by $4.9 million to $0.4 million in the first quarter (Q1 2024 – $5.3 million) reflecting the lower TCRC rates realized under the Company's 2025 favorable offtake agreement terms.

¹ Q1 2024 results reflect the Company's 87.5% effective interest in Gibraltar for the period from January 1 to March 24, 2024 and 100% effective interest for the period from March 25 to March 31, 2024.

Site operating costs decreased by $10.8 million to $68.9 million in the first quarter (Q1 2024 – $79.7 million) primarily driven by increased capitalized stripping costs related to the current pushback in the Connector pit. Site operating costs also benefited from lower input prices such as diesel and lower consumption of key mining consumables including diesel as the first part of 2024 mine operations involved longer haul distances from the bottom of the Gibraltar pit. Lower mining costs in the current quarter were partially offset by higher milling costs due to higher throughput and additional costs incurred to process the lower quality stockpile material.

Transportation costs decreased by $4.2 million to $6.0 million in the first quarter (Q1 2024 – $10.2 million) reflecting the lower sales volume during the quarter.

Cost of sales is also impacted by changes in finished goods and stockpile inventories. Stockpiled ore material was used to supplement mined ore in the first quarter depleting 5.5 million tons of sulphide ore stockpiles and contributing to an increase in production costs of $28.3 million during the quarter. Copper finished goods inventories decreased by 1.8 million pounds due to shipment timing and contributed to an increase in cost of sales of $2.7 million in the first quarter. Oxide ore stockpiles increased by 2.2 million tons as Gibraltar continues to mine

through the oxide ore layer in the Connector pit and add material to the heap leach pads. This contributed to a decrease in production costs of $5.5 million in the quarter.

In the comparative prior year quarter, cost of sales included $13.4 million of fair value adjustments related to the sale of concentrate inventory held at the date of acquisition of control of Gibraltar (March 25, 2024) arising from the Company's acquisition of Cariboo.

Depletion and amortization increased by $7.4 million to $22.4 million in the first quarter (Q1 2024 – $15.0 million) for depreciation included stockpile inventory costs that were processed during the quarter.

1 The $15.0 million gain on acquisition of control of Gibraltar in Q1 2024 relates to the write-up to fair value for Taseko's 87.5% interest in Gibraltar finished copper concentrate inventory held at the date of acquisition of control of Gibraltar (March 25, 2024) as a result of the Company's acquisition of Cariboo.

General and administrative expenses of $3.3 million in the first quarter were consistent with costs incurred in the comparative prior year quarter.

Share-based compensation expenses is comprised of the expense associated with share options and performance share units, and fair value adjustments on deferred share units and restricted share units. Share-based compensation expenses decreased by $0.4 million to $5.0 million in the first quarter (Q1 2024 – $5.4 million) primarily due to the decrease in the Company's share price and its impact on the valuation of deferred and restricted share units. For more information, refer to the Financial Statements—Note 18.

Realized loss on derivative instruments was $1.6 million in the first quarter consistent with $1.7 million in the comparative prior year quarter and pertains to the amortization of premiums paid for copper collars and fuel calls held by the Company as part of the Company's hedging strategy. Unrealized loss on derivative instruments was $21.6 million in the quarter compared to $0.9 million in the comparative prior year quarter and relates to the change in fair value on the Company's outstanding copper collars and fuel call options reflecting the increasing copper price trend during the current quarter.


TASEKO MINES LIMITED

Management's Discussion and Analysis

Unrealized loss on Florence copper stream derivative was $5.3 million in the first quarter compared to $2.6 million in the comparative prior year quarter and reflects upward changes in forward copper prices and discount rates applied over the Florence copper stream term.

Unrealized gain on Cariboo contingent performance payment was $3.3 million in the first quarter and reflects changes in forecast copper prices and Gibraltar revenues over the Sojitz earn-out period.

Project evaluation expense represent costs associated with the New Prosperity project and other technical expenditures undertaken by Taseko's engineering and technical teams on various project initiatives.

On March 25, 2024, the Company completed its acquisition of the remaining 50% of Cariboo from Dowa and Furukawa and increased its effective interest in Gibraltar from 87.5% to 100%. The Company recognized a gain on acquisition of Cariboo of $47.4 million representing the difference between the estimated fair value of net assets acquired and the estimated fair value of total consideration payable. The acquisition also gave the Company full control over Gibraltar resulting in the remeasurement of its previously held 87.5% interest in Gibraltar according to IFRS accounting standards. The Company recognized a gain on acquisition of control of Gibraltar of $15.0 million representing the fair value adjustment on finished copper concentrate inventory held at the date of acquisition to fair value. Further details on the Cariboo acquisition can be found in the Financial Statements—Note 12b.

Net finance expenses were $10.9 million in the first quarter compared to $11.7 million in the prior year quarter. Interest expense increased by $2.5 million to $17.3 million in the quarter (Q1 2024 – $14.8 million), primarily driven by the impact of the higher principal and coupon of the 8.25% senior secured notes due May 2030 that were issued in April 2024 being captured in the current quarter and not the comparative prior year quarter. Capitalized interest attributable to the funding of Florence Copper development costs increased by $3.0 million to $5.8 million in the quarter (Q1 2024 – $2.7 million) proportionate with the increased spending for the construction of the Florence Copper commercial production facility.


TASEKO MINES LIMITED

Management's Discussion and Analysis

Accretion expenses decreased by $0.4 million to $6.7 million in the first quarter (Q1 2024 – $7.0 million) primarily due to the decreases in accretion on Cariboo consideration payable and the Florence royalty obligation reflecting lower forecast copper prices over the terms of the obligations, offset by increases in accretion on deferred revenue reflecting higher silver ounces delivered under the Osisko silver stream in the current quarter.

¹ Excludes current portion of long-term debt.

The Company's asset base is principally comprised of property, plant and equipment reflecting the capital-intensive nature of its large scale, open pit mining operation at Gibraltar and construction of the commercial facility at Florence. Other current assets primarily include accounts receivable, inventories (concentrate inventories, ore stockpiles and supplies), prepaid expenses, and marketable securities. Concentrate inventories, accounts receivable and cash balances can fluctuate due to the timing of sales and cash settlements.

Property, plant and equipment increased $131.2 million in the first quarter, which includes Florence Copper construction costs of $83.2 million (capital project costs of $75.5 million and site costs of $7.7 million) and Gibraltar capital expenditures of $58.1 million (capitalized stripping costs of $44.0 million and other capital expenditures of $14.1 million).

Net debt increased $48.1 million in the first quarter, primarily due to decreases in cash and equivalents as the Company continues its funding of construction of the Florence Copper commercial facility and the effect of a stronger US dollar and the foreign exchange impact on US dollar-denominated borrowings, offset by repayments of the Company's equipment financings during the quarter.

Cariboo consideration payable relates to earn-out payments on the acquisition of Cariboo. Cariboo consideration payable decreased by $12.2 million primarily due to payments made to Sojitz of $10.0 million in the first quarter.


TASEKO MINES LIMITED

Management's Discussion and Analysis

Deferred revenue relates to the advance payments received from Osisko for the delivery of future silver production from Gibraltar and customer advance payments on copper concentrate.

Other liabilities increased by $14.7 million in the first quarter primarily due to the receipt of the final US$10.0 million instalment on the Mitsui copper stream.

At May 1, 2025, there were 315,875,348 common shares and 11,161,200 stock options outstanding. More information on these instruments and the terms of their exercise can be found in the Financial Statements—Notes 17 and 18.

Liquidity, cash flow and capital resources

At March 31, 2025, the Company had cash and equivalents of $120.8 million (December 31, 2024 – $172.7 million) and available liquidity of $279.0 million (December 31, 2024 – $331.0 million).

Cash flows provided by operations were $55.9 million in the first quarter compared to $59.6 million in the comparative prior year quarter. Operating margins from Gibraltar decreased in the quarter as a result of lower sales volumes but operating cash flows benefited from the release of stockpile inventories in the quarter, the costs for which were incurred in prior periods.

Cash flows used for investing activities were $130.9 million in the first quarter compared to $46.7 million in the comparative prior year quarter. Investing activities include $51.7 million for capital expenditures at Gibraltar (capitalized stripping of $38.1 million and sustaining capital expenditures of $13.6 million) and $80.0 million for capital expenditures at Florence Copper including $7.7 million in site costs.

Cash flows provided by financing activities were $21.5 million in the first quarter compared to $48.5 million in the comparative prior year quarter. Financing activities include $29.6 million (US$21.1 million) in net proceeds from shares issued under the Company's ATM equity offering prospectus and $14.4 million (US$10 million) from the final instalment of the US$50 million Mitsui copper stream offset by $10.2 million in debt repayments and $3.0 million in interest payments and $10.0 million payment to Sojitz related to the acquisition of Cariboo.

Liquidity outlook

At March 31, 2025, the Company had approximately $279.0 million (December 31, 2024 – $331.0 million) of available liquidity including $120.8 million in cash and equivalents and US$110 million undrawn capacity on its Credit Facility. The Company drew US$25 million from its Credit Facility in April.

In the first quarter, the Company completed its ATM offering and issued 10.6 million common shares for gross proceeds of $31.0 million (or US$21.5 million). The Company also received the final US$10 million instalment on the US$50 million Mitsui copper stream.

The Company expects to return to life of mine average copper production of 120 to 130 million pounds after the current pushback in the Connector pit is completed. The Company initiated a pushback in the Connector pit in the first quarter, which is expected to continue through the second quarter. During this period, lower quality ore stockpiles are being used to supplement mined ore and as such 2025 production will be weighted heavily towards the second half of the year. Molybdenum production is also expected to increase due to higher expected molybdenum grades in Connector pit ore.

TASEKO MINES LIMITED

Management's Discussion and Analysis

Refurbishment of Gibraltar's SX/EW plant is now complete and is expected to start producing copper cathode in the second quarter to supplement Gibraltar's copper production in concentrate from its concentrator mills. Gibraltar has no other significant capital projects planned for the remainder of 2025.

The Company has significant capital commitments for the remaining construction of the Florence commercial facility. The Company intends to finance the remaining capital costs over the next 12 months from available liquidity, cash flows from Gibraltar and its corporate Credit Facility.

If needed, the Company could raise further additional capital through equity financings or asset sales, including royalties, sales of project interests, or joint ventures, or additional credit facilities, including additional notes offerings or increasing borrowings from commercial banks or credit funds. The Company evaluates these financing alternatives based on a number of factors, including the prevailing metal prices and projected operating cash flows from Gibraltar, relative valuation, liquidity requirements, covenant restrictions and other factors, in order to optimize the Company's cost of capital and maximize shareholder value.

Future changes in copper and molybdenum market prices could also impact the timing and amount of cash available for future investment in the Company's capital commitments and development projects, debt obligations and other uses of capital. To mitigate commodity price risks in the short term, copper price options are entered into for a substantial portion of Gibraltar's copper production and the Company has a long track history of doing so. The Company currently has copper price protection in place for 81 million pounds of production for the remainder of the year.

Hedging strategy

The Company generally fixes all or substantially all of the copper prices of its copper concentrate shipments at the time of shipment. Where the customer's offtake contract does not provide a price fixing option, the Company may look to undertake a quotational period hedge directly with a financial institution as the counterparty in order to fix the price of the shipment.

To protect against sudden and unexpected copper price volatility in the market, the Company's hedging strategy aims to secure a minimum price for a significant portion of future copper production using copper put options that are either purchased outright or substantially funded by the sale of copper call options that are out of the money. The amount and duration of the copper hedge positions is based on an assessment of business-specific risk elements combined with the copper pricing outlook. Copper price and quantity exposure are reviewed regularly to ensure that adequate revenue protection is in place.

Hedge positions are typically extended by adding incremental quarters at established floor prices (the strike price of the copper put option) to provide the necessary price protection. Considerations for the cost of the hedging program include an assessment of Gibraltar's estimated production costs, copper price trends and the Company's fixed capital requirements during the relevant period. During periods of volatility or step changes in the copper price, the Company may revisit outstanding hedging contracts and determine whether copper put (floor) or call (ceiling) levels should be adjusted in line with the market while maintaining copper price protection.

From time to time, the Company will look at potential hedging opportunities that mitigate the risk of rising input costs, including foreign exchange and fuel prices, where such a strategy is cost effective. To protect against a potential operating margin squeeze that could arise from oil and diesel price shocks, the Company purchases fuel

call options to provide a price ceiling for diesel that is used by the mining fleet. The Company does not apply hedge accounting to any of its commodity or input cost derivatives.

1 On March 15, 2023, the Company completed the acquisition of 50% of Cariboo from Sojitz. The acquisition price payable to Sojitz is a minimum of $60 million payable over a 5-year period and potential contingent payments depending on Gibraltar copper revenue and copper prices. $30 million of the $60 million minimum amount has been paid to Sojitz as of March 31, 2025. The remaining minimum amounts will be paid in $10 million annual instalments over the next 3 years. There is no interest payable on the minimum amounts. The Company also estimates $30 million will be payable over the next 3 years related to the contingent consideration, which has not been included in the table above.

2 On March 25, 2024, the Company completed the acquisition of the remaining 50% of Cariboo from Dowa and Furukawa. The acquisition price payable to Dowa and Furukawa is a minimum of $117 million and a maximum of $142 million payable over a 10-year

period. The quantum and timing of these payments depends on copper prices and Gibraltar cash flow. An initial payment of $5 million was paid to Dowa and Furukawa on closing, with remaining consideration payable in annual instalments starting in April 2026.

3 Provisional for environmental rehabilitation amounts presented represent the present value of estimated costs of legal and constructive obligations required to retire an asset, including decommissioning and other site restoration activities, primarily for Gibraltar and Florence. At March 31, 2025, the Company has provided surety bonds for $124.2 million for Gibraltar's reclamation security and $51.9 million for Florence's reclamation security.

4 Transportation-related services include ocean freight and port handling services, which are both cancelable upon certain operating circumstances.

At March 31, 2025, the Company has capital expenditure commitments relating to the Florence Copper commercial facility construction project totaling $24.6 million (December 31, 2024 – $47.9 million).

In December 2024, Gibraltar received an amendment to its M-40 permit in which the required closure bonding with the Province of BC to increase from $108.5 million to $139.9 million. Gibraltar was required to post this additional bonding over the next 15 months and in March 2025 posted additional surety bonds of $15.7 million to the Province of BC. The Company intends to post additional surety bonds to meet the remaining bonding requirements from insurance underwriters.

Critical Accounting Policies and Estimates

The Company's material accounting policies are presented in Note 2.4 of the 2024 annual consolidated financial statements. The preparation of the financial statements in conformity with IFRS requires management to make judgments, estimates and assumptions that affect the application of accounting policies, including the accounting for the Cariboo acquisition, 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 the timing of transfer of control of inventory for revenue recognition, provisions for environmental rehabilitation, reserve and resource estimation, functional currency, the determination of the accounting treatment for the advance payment under the silver purchase and sale agreement reported as deferred revenue, and recovery of other deferred tax assets.

Significant areas of estimation include reserve and resource estimation, fair value of assets and liabilities acquired in a business combination, asset valuations and the measurement of impairment charges or reversals, valuation of inventories, plant and equipment lives, tax provisions, provisions for environmental rehabilitation, 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 Financial Statements.

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 revisions 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 reserve 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, inventories, property, plant and equipment, and intangibles, as well as the measurement of impairment charges or reversals. These factors also impacted the fair values of assets and liabilities recorded on the acquisition of Cariboo disclosed in the Financial Statements—Notes 12 and 14.

Internal and Disclosure Controls Over Financial Reporting

The Company's management is responsible for establishing and maintaining adequate internal controls over financial reporting ("ICFR") and disclosure controls and procedures ("DC&P").

The Company's internal control system over financial reporting is designed to provide reasonable assurance to management and the Board of Directors regarding the preparation and fair presentation of published financial statements. Internal controls 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 assets of the Company;


TASEKO MINES LIMITED

Management's Discussion and Analysis

(2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with IFRS Accounting Standards, 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.

The Company's internal control system over disclosure controls and procedures is designed to provide reasonable assurance that material information relating to the Company is made known to management and disclosed to others and information required to be disclosed by the Company in its annual filings, interim filings or other reports filed or submitted by us under securities legislation is recorded, processed, summarized and reported within the time periods specified in the securities legislation.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined effective can provide only reasonable assurance with respect to financial reporting and disclosure.

There have been no changes in our internal control over financial reporting and disclosure controls and procedures during the three months ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, internal control over financial reporting and disclosure.

Key Management Personnel

Key management personnel ("KMP") include the members of the Board of Directors and executive officers of the Company.

The Company contributes to a post-employment defined contribution pension plan on behalf of certain KMP. This retirement compensation arrangement (the "RCA Trust") was established to provide benefits to certain executive officers on or after retirement in recognition of their long service. Upon retirement, the participant is entitled to the distribution of the accumulated value of the contributions under the RCA Trust. Obligations for contributions to the defined contribution pension plan are recognized as compensation expense in the periods during which services are rendered by the executive officers.

Certain executive officers are entitled to termination and change in control benefits. In the event of termination without cause, other than a change in control, these executive officers are entitled to an amount ranging from 12-months' to 18-months' salary. In the event of a change in control, if a termination without cause or a resignation occurs within 12 months following the change in control, these executive officers are entitled to receive, among other things, an amount ranging from 12-months' to 24-months' salary and accrued bonus, and all stock options held by these individuals will fully vest.

Executive officers and directors also participate in the Company's share option program (refer to the Financial Statements—Note 18).

Non-GAAP Performance Measures

This MD&A includes certain non-GAAP performance measures that do not have a standardized meaning prescribed by IFRS. These measures may differ from those used by, and may not be comparable to such measures as reported by, other issuers. The Company believes that these measures are commonly used by certain investors, in conjunction with conventional IFRS measures, to enhance their understanding of the Company's performance. These measures have been derived from the Company's financial statements and applied on a consistent basis. The following tables below provide a reconciliation of these non-GAAP measures to the most directly comparable IFRS measures.

Total operating cost and site operating cost, net of by-product credit

Total operating cost includes all costs absorbed into inventory, as well as transportation costs and insurance recoverable. Site operating cost is calculated by removing net changes in inventory, depletion and amortization, insurance recoverable, and transportation costs from cost of sales. Site operating cost, net of by-product credit is calculated by subtracting by-product credits from site operating cost. Site operating cost, net of by-product credit per pound is calculated by dividing the aggregate of the applicable costs by pounds of copper produced. Total operating cost per pound is the sum of site operating costs, net of by-product credits and off-property costs divided by pounds of copper produced. By-product credit is calculated based on actual sales of molybdenum (net of treating costs) and silver during the period divided by the total pounds of copper produced during the period. These measures are calculated on a consistent basis for the periods presented.

Adjusted net income (loss) and Adjusted EPS

Adjusted net income (loss) removes the effect of the following transactions from net income (loss) as reported under IFRS:

  • Unrealized foreign currency gains and losses;
  • Unrealized derivative gains and losses and fair value adjustments;
  • Other operating costs;
  • Call premium on settlement of debt;
  • Loss on settlement of debt, net of capitalized interest;
  • Bargain purchase gains on Cariboo acquisition;
  • Gain on acquisition of control of Gibraltar;
  • Realized gain on sale of finished goods inventory;

  • Inventory write-ups fair value that was sold or processed;
  • Accretion on Florence royalty obligations;
  • Accretion on Cariboo consideration payable;
  • Non-recurring other expenses for Cariboo adjustment; and
  • Finance and other non-recurring costs of Cariboo acquisition.

Management believes these transactions do not reflect the underlying operating performance of the Company's core mining business and are not necessarily indicative of future operating results. Furthermore, unrealized gains and losses on derivative instruments, changes in the fair value of financial instruments, and unrealized foreign currency gains and losses are not necessarily reflective of the underlying operating results for the periods presented.

  • Unrealized foreign exchange gains and losses;
  • Unrealized derivative gains and losses and fair value adjustments;
