Taseko Mines released a progress update at its Florence Copper Project and production results for the Gibraltar Mine.

Construction activity at Florence Copper is now complete and the focus has shifted to wellfield operations and commissioning of the SX/EW plant. Wellfield acidification commenced in early November, and in early December mining solutions were circulating in all the new production wells within the commercial wellfield. Injection flowrates in the wellfield have met or exceeded expectations to-date, resulting in faster initial acidification of the wellfield. 

The grade of copper recovered in solution from the recovery wells has continued to increase, and the average solution grade has now reached the level required for SX/EW plant operations. Commissioning of the SX/EW plant area has been advancing without any significant issues, and plant operations are expected to commence shortly.

Wellfield drilling has also re-commenced with three drill rigs currently operating on site. Continued expansion of the commercial wellfield will support higher solution flows and increased copper production for the ramp-up this year.

“The transition from construction to early-stage operations at Florence has gone smoothly, and we are very pleased with the initial copper recoveries and performance of the commercial wellfield. Our project team is focused on the successful start-up of the SX/EW plant in the coming days, followed by first copper cathode production within a few weeks,” Stuart McDonald, president and CEO of Taseko.

At the Gibraltar Mine, copper and molybdenum production for the 2025 year was 98 million pounds and 1.9 million pounds. Sales for the year were 99 million pounds of copper and 1.9 million pounds of molybdenum. Fourth quarter copper production was 31 million pounds of copper, a significant increase over the previous quarters of 2025. Production in the fourth quarter was impacted by unanticipated mill downtime, due to unscheduled maintenance activities and a serious accident which resulted in a temporary site wide shut down in November. Molybdenum production in the quarter was 0.8 million pounds, approximately 50 percent higher than the third quarter, and the best quarterly production in eight years. Gibraltar’s SX/EW plant produced 0.9 million pounds of copper cathode in the fourth quarter, and continues to operate.

“Gibraltar production in the second half of the year was a notable improvement over the first half of the year with higher grades and better quality ore. Looking ahead to 2026, we expect more consistent quarterly production, now that we are better situated in the connector pit, and higher overall copper production,” said McDonald.

Headquartered in Vancouver, British Columbia, Canada, Taseko Mines is a dynamic North American mining company driven to unlock the true value of copper for its investors, employees, communities, and for a complex and changing world. Taseko’s corporate strategy has been to grow the company sustainably and profitably by focusing on the continued operations of its foundational asset, the Gibraltar Mine in central BC, and the advancement of North America’s next copper producer, Florence Copper in Arizona — while also advancing its pipeline of high-quality, advanced-stage development projects, including the Yellowhead copper project and the Aley niobium project.
