Taseko Mines Limited filings document a Canadian foreign issuer with copper mining operations and development projects in North America. Form 6-K submissions include press releases, interim and annual financial statements, management discussion and analysis, and exhibits related to operating results at Gibraltar and Florence Copper.
The company’s financial disclosures describe IFRS reporting, cash, inventories, property, plant and equipment, long-term debt, Florence financings, royalty and copper stream obligations, deferred revenue, and environmental rehabilitation provisions. Filing exhibits also record auditor consents, amended financial statements, internal-control responsibilities, capital-structure items, production updates, and project-level disclosures tied to copper, molybdenum and mineral development assets.
Taseko Mines Limited has begun producing copper at its Florence Copper operation in Arizona, marking a major step in its growth strategy. The site has harvested its first copper cathodes from the new commercial facility, representing the first new copper production from a greenfield operation in the United States since 2008.
Once Florence Copper reaches its nameplate capacity of 85 million pounds of LME Grade A copper per year, Taseko expects to become the third-largest copper cathode producer in America. The operation is projected to produce a minimum of 1.5 billion pounds of copper over 22 years, using in-situ copper recovery (ISCR), a low-cost method with environmental advantages over conventional mining. All copper produced at Florence is planned to remain in the United States, supplying sectors such as automotive, semiconductors, defense/aerospace and AI data centers.
Taseko Mines reported solid 2025 operating performance while turning on its second mine. Full-year 2025 revenue was $672.9 million, with Adjusted EBITDA of $230.4 million and earnings from mining operations before depletion and non-recurring items of $250.7 million. The year still showed a net loss of $30.1 million or $0.09 per share, while Adjusted net income was $27.1 million or $0.07 per share.
In the fourth quarter, results strengthened: revenue reached $243.8 million, Adjusted EBITDA was $116.5 million, cash flow from operations was $101.2 million, and net income was $4.5 million. The Gibraltar mine produced 98.1 million pounds of copper in 2025 at C1 costs of US$2.66 per pound, with Q4 C1 costs improving to US$2.47 per pound as grades and recoveries rose.
A major milestone was the commencement of copper cathode production at Florence Copper, where the SX/EW plant is now fully operational and 2026 output is targeted at 30–35 million pounds. Gibraltar’s 2026 copper production is guided to 110–115 million pounds. Taseko also advanced its growth pipeline, publishing a new technical report for the Yellowhead copper project with an after-tax net present value of $2.0 billion and receiving a $75 million payment tied to the New Prosperity copper-gold project agreement with the Tŝilhqot’in Nation and the Province of BC.
Taseko Mines Limited filed its annual consolidated financial statements, showing higher 2025 revenue but a net loss as it advances major growth projects. Revenue rose to $672.9 million from $608.1 million, driven by copper and molybdenum sales from the Gibraltar mine in British Columbia.
The company reported a net loss of $30.1 million, compared with a $13.4 million loss in 2024, as large non-cash losses on derivatives, higher share-based compensation, and substantial finance and accretion costs offset operating profits. Earnings from mining operations improved to $152.0 million from $124.8 million.
Cash provided by operations was strong at $219.6 million, but Taseko spent $425.8 million on investing activities, largely for Florence Copper development and Gibraltar stripping and capital projects. Financing activities added $224.5 million of cash, including $258.6 million in net share issuances and $71.8 million from the New Prosperity transaction.
Total assets increased to $2.47 billion and equity to $778.7 million, while total liabilities were $1.69 billion. Management concluded internal control over financial reporting was effective as of December 31, 2025, and PricewaterhouseCoopers LLP issued unqualified opinions on both the financial statements and internal controls.
