Except where otherwise noted, all currency amounts are stated in Canadian dollars. In March 2024 Taseko acquired the remaining 12.5% interest and now owns 100% of the Gibraltar Mine, located north of the City of Williams Lake in south-central British Columbia. Production and sales volumes stated in this release are on a 100% basis unless otherwise indicated.

VANCOUVER, BC, May 1, 2024 -- Taseko Mines Limited (TSX: TKO) (NYSE American: TGB) (LSE: TKO) ("Taseko" or the "Company") reports first quarter 2024 Adjusted EBITDA* of $50 million and Earnings from mining operations before depletion and amortization* of $53 million, 38% and 29% higher than the same quarter in 2023. Revenues for the first quarter were $147 million. Net income for the quarter was $19 million ($0.07 per share) and Adjusted net earnings* were $8 million ($0.03 per share).

In the first quarter, Gibraltar produced 30 million pounds of copper and 247 thousand pounds of molybdenum. Mill throughput in the quarter was 7.7 million tons, or 84,400 tons per day, processing an average grade of 0.24% copper. Total operating cash costs (C1)* for the quarter were US$2.46 per pound of copper.

Stuart McDonald, President and CEO of Taseko, commented, "Gibraltar operations performed generally in line with plan in the first quarter, generating strong margins on a realized copper sales price of US$3.89 per pound. The operating team successfully completed a mill component replacement in January and following this maintenance downtime, mill throughput averaged 90,000 tons per day, 6% above the design capacity. The gradual transition to the Connector pit will continue over the next few months, and the in-pit crusher relocation is planned for the second quarter."

"In late March we acquired the remaining 12.5% interest in Gibraltar and now own 100% of the mine. This transaction is a real positive for Taseko, providing immediate cashflow and production growth. The acquisition cost is spread out over ten years, with the next scheduled payment in 2026, which allows us to focus our financial resources on Florence development. As part of the transaction, we also acquired additional concentrate offtake rights and, with smelter treatment costs at record lows, the timing could not have been better. This additional offtake has now been sold at negative treatment costs, resulting in cost savings of $10 million in the second half of 2024," continued Mr. McDonald.

"At Florence Copper, initial construction and wellfield development activities are progressing smoothly. There are now three drill rigs operating on the commercial facility wellfield, with a fourth drill to be mobilized in May. A total of ten new production wells have been drilled to date. Site preparation and earthworks for the SX/EW plant area are also underway and construction of the plant is expected to begin later this quarter. It is an exciting time for the Company as we move closer to commercial operations at Florence.

In April, we further strengthened our financial position through the successful refinancing of our senior secured notes. The maturity of the notes has been pushed out to 2030, and the upsizing provides additional cash proceeds and financial flexibility. With the bond refinancing complete, 100% ownership of Gibraltar, and the copper price today at US$4.49 per pound, our business is much improved from just a few months ago." concluded Mr. McDonald.
