Taseko Reports First Quarter 2025 Earnings

This release should be read with the Company’s Financial Statements and Management Discussion & Analysis ("MD&A"),

available at www.tasekomines.com and filed on www.sedarplus.com . Except where otherwise noted, all currency

amounts are stated in Canadian dollars. Taseko owns 100% of the Gibraltar Mine, which is located north of the City of

Williams Lake in south-central British Columbia.

VANCOUVER, British Columbia, May 01, 2025 -- Taseko Mines Limited (TSX: TKO; NYSE American: TGB; LSE: TKO)

("Taseko" or the "Company") reports first quarter 2025 Adjusted EBITDA* of $34 million and Earnings from mining operations

before depletion and amortization and non-recurring items* of $39 million. Revenues for the first quarter were $139 million from

the sale of 22 million pounds of copper and 364 thousand pounds of molybdenum. The Company recorded a Net loss of $29

million ($0.09 loss per share) and an Adjusted net loss* of $7 million ($0.02 loss per share).

Gibraltar produced 20 million pounds of copper and 336 thousand pounds of molybdenum in the first quarter at Total operating

costs (C1) of US$2.26 per pound of copper produced. Mill throughput averaged 87,800 tons per day, which was above design

capacity. Copper grades in the quarter averaged 0.19% and copper recoveries were 68%.

At Florence Copper, construction remains on schedule and as of the end of March the overall project completion was at 78%.

Construction of the SX/EW plant, surface infrastructure and the wellfield drilling are tracking to plan. In the wellfield, drilling is

nearly complete and the last two wells will be constructed in May.  The electrowinning crane has been installed in the plant,

allowing the building structure to be completed. Construction of surface infrastructure is also advancing on schedule, including

work on the pipe corridor, electrical substation, tank farm, and office and dry buildings.

Stuart McDonald, President and CEO of Taseko, commented, “Through the first 15 months of construction at Florence

Copper, all critical aspects of the project remain on schedule and our operating plans are well developed. In the coming

months, site construction activities will begin to slow down and in the fall we expect to commence wellfield operations as we

advance towards first copper cathode production later in the year. Our project team remains focussed on continued execution

of the remaining construction activities, and our growing operations team is planning for the production ramp up in 2026.”

“At our Gibraltar mine, mill throughput exceeded design capacity in the first quarter and head grades were in line with plan. 

But copper production in the quarter was impacted by lower than expected metallurgical recoveries from oxidized ore.  Also,

challenging ground conditions at the top of the current Connector pit pushback have led to lower mining productivities in recent

months which will delay the release of higher-grade ore from the second quarter to the third quarter.  As a result, copper

production for 2025 is expected to be about 10 million pounds (~8%) lower than our previous guidance.  Significantly higher

grades and recoveries are expected in the second half of this year and into 2026”, continued Mr. McDonald.

Mr. McDonald concluded, “With less than nine months until the startup of Florence Copper, America’s next copper mine,

Taseko is approaching a period of significant production and cashflow growth.  We are uniquely positioned as the North

American copper producer with both near-term production growth and a longer-term growth pipeline.”

Operations Analysis

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.

*Non-GAAP performance measure. See end of news release.

Operations Analysis - Continued

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:

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.

*Non-GAAP performance measure. See end of news release.

Gibraltar Outlook - Continued

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).

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 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).

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 Tŝilhqot’in Nation, as represented by the Tŝilhqot’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 Tŝilhqot’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 Teẑtan Biny

(Fish Lake).

This dialogue process has made meaningful progress in recent months and is close to completion. The Tŝilhqot’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.

Conference Call and Webcast

The Company will host a telephone conference call and live webcast on Friday, May 2, 2025, at 11:00 a.m. Eastern Time

(8:00 a.m. Pacific) to discuss these results.  After opening remarks by management, there will be a question-and-answer

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.

measure of the Company’s performance and ability to service debt.  Adjusted EBITDA is frequently used by securities

analysts, investors and other interested parties in the evaluation of companies in the industry, many of which present adjusted

EBITDA when reporting their results.  Issuers of “high yield” securities also present adjusted EBITDA because investors,

analysts and rating agencies considering it useful in measuring the ability of those issuers to meet debt service obligations.

Adjusted EBITDA represents net income before interest, income taxes, depreciation and amortization, and also eliminates the

impact of a number of transactions that are not considered indicative of ongoing operating performance.  Certain items of

expense are added back and certain items of income are deducted from net income that are not likely to recur or are not

indicative of the Company’s underlying operating results for the reporting periods presented or for future operating performance

and consist of:

• Unrealized foreign exchange gains and losses;

• Unrealized derivative gains and losses and fair value adjustments;

• Amortization of share-based compensation expense;

• Other operating costs;

• Call premium on settlement of debt;

• Loss on settlement of debt;

• Bargain purchase gains on Cariboo acquisition;

• Gain on acquisition of control of Gibraltar;

• Realized gains on sale of finished goods inventory;
