Lion Copper

Lion Copper Corp. (formerly Lion Copper and Gold Corp. and Quaterra Resources Inc.) is an exploration- and development-stage mineral resources company primarily focused on copper deposits in North America. The company's flagship asset is the 100%-controlled Yerington Copper Project in the Mason Valley of Lyon County, Nevada, which spans over 26,000 acres and comprises several significant deposits, including the Yerington brownfield open pit, the MacArthur copper oxide/sulfide deposit, and the deep Bear porphyry deposit. In addition to its Nevada footprint, the company maintains prospective copper exploration interests in Montana, Alaska, and British Columbia. Lion Copper operates under a pre-revenue exploration and development model, with project funding and technical de-risking substantially supported by an earn-in agreement with Nuton LLC, a wholly owned subsidiary of Rio Tinto. Under this framework, Nuton can earn up to a 65% interest in the project by funding multi-stage work programs through definitive feasibility study and permitting milestones. The development strategy centers on utilizing Nuton's proprietary bio-heap-leach processing technology alongside run-of-mine heap leaching and solvent extraction-electrowinning (SX-EW) to recover copper from both oxide and primary sulfide mineralization without the need for traditional flotation and smelting. A 2025 pre-feasibility study outlined an initial 12-year mine life targeting average annual production of approximately 120 million pounds of payable copper cathode.
