Taseko Mines Limited has reached a critical inflection point as it formally transitions the Florence Copper project from construction to early operations. On January 13, 2026, the company confirmed that the SX/EW plant is now in commissioning phase, with first copper cathode production expected within weeks. This milestone coincides with a strong year-end production update from the Gibraltar Mine, which posted 98 million pounds of copper for 2025 and its highest quarterly molybdenum output in nearly a decade. The update sent Taseko Mines Limited’s stock surging over 4 percent on the London Stock Exchange, closing at 470 GBX and capping off a 12-month rally that has more than doubled the share price since January 2025.
Investors and industry analysts are now positioning the company as a credible dual-asset copper producer, one that has successfully executed two complex operational trajectories in parallel. Florence Copper is Taseko Mines Limited’s flagship United States asset, an in-situ recovery project located in Arizona that has now entered a critical transition from development to production. Gibraltar remains the company’s legacy open-pit mine in British Columbia, and it continues to deliver material output despite ongoing operational and geological complexities.
How does Florence Copper’s progress shift the company’s value narrative entering 2026?
The most important strategic development for Taseko Mines Limited is that construction at Florence Copper has officially concluded, with the SX/EW plant now in commissioning. This marks the end of a capital-intensive multi-year development cycle and opens the door to production-linked revenue without additional large-scale investment. The Florence wellfield has been performing above modeled expectations since injection flow commenced in November 2025, and acidification has occurred at an accelerated pace. By early December, mining solutions were circulating across all new production wells, and recovery grades had reached thresholds necessary to operate the solvent extraction and electrowinning system.
That performance not only reinforces the technical underpinnings of the project’s in-situ design but also signals smoother scaling conditions for 2026. In-situ recovery is inherently complex during early cycles, often facing bottlenecks related to flow dynamics, acid strength, and orebody permeability. Taseko Mines Limited’s ability to exceed flowrate expectations and maintain grade consistency across its commercial wellfield reduces early-stage risk and strengthens the case for achieving nameplate production capacity on schedule. Three active drill rigs are now operational on-site, focused on expanding the wellfield to lift copper yields as the ramp-up continues. This step underscores management’s commitment to optimizing output early, rather than deferring upgrades or spacing out production targets over longer horizons.
From a capital markets perspective, Florence Copper’s move into operations also changes how Taseko Mines Limited is modeled. Investors have long treated the company as a single-asset operator with project development optionality. That view is now outdated. Florence represents a second source of primary production, located in a politically stable, resource-friendly jurisdiction that aligns with broader North American copper sourcing strategies. In a tightening copper supply environment, domestic projects with low carbon intensity and scalable SX/EW output become significantly more valuable.
What operational signals are emerging from Gibraltar’s year-end production results?
Gibraltar delivered full-year copper production of 98 million pounds and molybdenum production of 1.9 million pounds in 2025, with a marked acceleration in the final quarter. Fourth-quarter copper production reached 31 million pounds, driven by improved head grade of 0.26 percent and a recovery rate of 81 percent. Molybdenum production in the final quarter came in at 0.8 million pounds, the highest quarterly output in eight years and nearly 50 percent higher than the previous quarter.
While the mine experienced unscheduled mill downtime in November, including a site-wide shutdown due to a serious safety incident, operations recovered quickly. Taseko Mines Limited also confirmed that the Gibraltar SX/EW plant produced 0.9 million pounds of copper cathode in Q4, indicating stable leaching performance even amidst broader maintenance challenges. These results point to a broader pattern of operational resilience and support management’s forward-looking guidance for more consistent output in 2026.
The second-half recovery at Gibraltar is particularly relevant because it reflects a successful transition into the Connector pit, which had previously been characterized by geotechnical complexity and lower-than-expected ore continuity. Access to better quality ore and improved plant performance have changed the operational tone of the asset. The stronger end to the year helps offset underperformance in the first half of 2025 and provides a more credible foundation for modeling annualized copper production rates going forward.
How is investor sentiment shifting around Taseko Mines Limited’s dual-asset strategy?
Taseko Mines Limited has enjoyed one of the strongest 12-month stock performances in the mid-tier copper segment. As of January 13, 2026, shares on the London Stock Exchange were trading at 470 GBX, up from under 200 GBX a year earlier. That rise reflects a combination of milestone execution at Florence Copper, production stabilization at Gibraltar, and rising investor appetite for exposure to copper projects with near-term output.
Unlike speculative juniors, Taseko Mines Limited has been able to generate this rerating through execution rather than forward-looking promises. Florence Copper is not a concept; it is now a de-risked production asset with physical commissioning underway. Gibraltar is no longer viewed as a volatile, single-pit operation but rather as a maturing mine that has regained operating rhythm and can be relied upon to fund corporate and expansion activities.
Investor sentiment has also been helped by the geographic distribution of the company’s asset base. Exposure to British Columbia and Arizona gives Taseko Mines Limited a platform across two well-established mining jurisdictions, both of which are viewed favorably by institutional capital. In particular, Florence Copper’s low-carbon, low-footprint in-situ recovery design fits well within ESG-aligned mandates, especially among funds looking to align with clean energy supply chains or North American electrification themes.
What are the key execution risks and capital constraints heading into the ramp-up phase?
Despite strong progress, execution risks remain across both assets. At Florence Copper, early-stage SX/EW commissioning must now translate into steady-state cathode output. Historically, SX/EW systems have faced scaling issues during startup due to reagent balance, organic carryover, and maintenance bottlenecks. In-situ recovery projects also require careful groundwater and pressure monitoring to ensure leach control, especially as wellfield expansion accelerates.
On the capital side, Taseko Mines Limited has not announced any new financing plans, suggesting that management aims to fund Florence Copper ramp-up through internal cash flow and existing liquidity. That decision underscores capital discipline, but it also places pressure on early output to meet cash generation targets. Should copper prices soften or operating costs rise unexpectedly, the company may need to explore credit-based options to sustain full expansion.
Gibraltar, while more stable, carries its own risks. The safety incident in November 2025 highlights the potential for unplanned disruptions, which could affect insurance costs, regulatory oversight, and workforce stability. Taseko Mines Limited will need to maintain heightened safety controls throughout 2026 to prevent further incidents and to reinforce its operational credibility with regulators and stakeholders.
How does Taseko Mines Limited compare to other mid-tier copper producers in 2026?
Taseko Mines Limited is now emerging as a uniquely positioned North American copper producer with diversified operations and proven commissioning capability. Few peers in the same market capitalization range have a second asset at this level of maturity or a U.S.-based in-situ production platform capable of near-term output. This places Taseko Mines Limited in a competitive group with companies like Capstone Copper, Hudbay Minerals, and Arizona Sonoran Copper, each of which is targeting similar U.S.-linked growth with varying degrees of technical and financial risk.
From a valuation standpoint, Taseko Mines Limited may continue to trade at a discount until Florence Copper enters full commercial production. But the completion of construction and commencement of SX/EW commissioning materially narrows the valuation gap. The presence of a producing SX/EW plant also strengthens the company’s long-term strategic appeal, especially in an environment where copper cathode from ESG-friendly sources is being priced at a premium by downstream buyers.
Over the next several quarters, the company’s ability to deliver consistent cathode output from Florence, maintain stable production from Gibraltar, and avoid capital raising will likely determine whether it can consolidate its gains or face downward pressure. If successful, Taseko Mines Limited may become a candidate for strategic partnerships or eventual acquisition by a larger copper-focused entity seeking U.S. exposure.
What Taseko Mines Limited’s Florence Copper ramp up and Gibraltar stabilization reveal about its 2026 growth and valuation trajectory
The convergence of production execution at Gibraltar and Florence Copper’s commissioning now gives Taseko Mines Limited operating momentum that has not existed in recent years. It also resets how the company is viewed by both institutional investors and sector peers. No longer a single-mine developer with long-dated promises, Taseko Mines Limited is now a two-asset producer with demonstrated capital discipline, diversified jurisdictional exposure, and an operational profile aligned with the strategic copper demands of the next decade.
The company’s trajectory in 2026 will be shaped by the speed and stability of Florence’s cathode output, the consistency of Gibraltar’s grade and recovery performance, and the broader macro backdrop for copper pricing. But the strategic groundwork appears sound. Execution risk remains, but credibility is building.
Taseko Mines Limited may not yet be the finished product in the eyes of global mining capital, but the company has now positioned itself to matter—and that is the foundation from which every breakout copper producer begins.
