November 12, 2025, Vancouver, BC – Taseko Mines Limited (TSX: TKO; NYSE American: TGB; LSE: TKO) ("Taseko" or the "Company") reports third quarter 2025 Adjusted EBITDA* of $62 million, a net loss of $28 million ($0.09 per share) and Adjusted net income* of $6 million ($0.02 earnings per share). Revenues for the third quarter were $174 million from the sale of 26 million pounds of copper and 421 thousand pounds of molybdenum.

Gibraltar copper production significantly improved over the previous two quarters as mining continued to advance deeper into higher grade ore in the Connector pit. In the third quarter, Gibraltar produced 27.6 million pounds of copper, which includes 895 thousand pounds of copper cathode, and 558 thousand pounds of molybdenum. Mill throughput for the quarter was in line with the nameplate capacity of 85,000 tons per day, and an average copper grade of 0.22% was processed. Copper recoveries for the third quarter were 77%. Both grade and recoveries were markedly higher than the previous two quarters and are expected to increase again in the fourth quarter. Molybdenum grades, which typically track copper grades, were also higher than the previous quarters resulting in much improved production.

Total operating (C1) cost * was US$2.87 per pound, lower than the previous quarter and expected to continue to trend downward in the fourth quarter.

At Florence Copper, the general contractor for the SX/EW plant area achieved substantial completion in September and began to demobilize construction crews. The focus has shifted to commissioning of the key processing circuits. Wellfield operations commenced in mid-October and are now ramping up with first solutions being injected in early November. Commissioning of the SX/EW plant will advance in parallel with the initial acidification of the wellfield and the facility is expected to produce first copper cathode early next year.

Stuart McDonald, President & CEO of Taseko, commented, “Our construction and operating teams at Florence have achieved a number of significant milestones in recent months and have successfully completed this major capital project in line with our execution plan. Initial flow rates in the commercial wellfield have been in line with expectations at this point of the wellfield ramp up process, and we’re now very close to first cathode production. Drilling activity will also restart on the wellfield in the next few weeks. These additional wells are required to ramp up cathode production in 2026.”

“Gibraltar copper production improved in the third quarter as mining advanced through the more complex mineralized zones, and copper grades and recoveries were stronger. The current benches in the Connector pit are expected to produce higher copper grades again in the fourth quarter and result in another increase in recoveries and copper production,” continued Mr. McDonald.

“The US$173 million equity financing that we successfully completed in October has significantly strengthened our balance sheet. A portion of the proceeds have now been used to pay off the US$75 million that was drawn on the corporate revolver. The working capital injection also allows us to restart wellfield drilling at Florence Copper, earlier than planned, which will benefit the ramp up in 2026.”

“Despite the recent price volatility, the fundamentals of the copper market remain healthy. Copper prices are expected to remain strong in 2026 as accelerating demand from electrification and constrained mine supply continue to tighten the global market,” concluded Mr. McDonald.
