- Capstone Copper Corp. is a Vancouver-based copper mining company, founded in 2021 and headquartered in Canada, that owns and operates a portfolio of long-life copper mines and development projects across the Americas, including the 100%-owned Pinto Valley open-pit copper-molybdenum mine in Arizona, United States; the 100%-owned Cozamin underground copper-silver-zinc-lead mine in Zacatecas, Mexico; the 100%-owned Mantos Blancos open-pit copper-silver mine in Chile's Antofagasta region; and a 70%-owned interest in the Mantoverde open-pit copper-gold mine in Chile's Atacama region, which produces copper cathodes from oxide heap leach operations and copper concentrates from sulphide ore following the completion of the Mantoverde Development Project (MVDP) sulphide concentrator expansion; the company also holds the fully permitted Santo Domingo copper-iron-gold development project with cobalt potential in Chile's Atacama region, along with the nearby Sierra Norte exploration property and additional exploration assets in the Americas, producing copper concentrates, copper cathodes, silver, gold, molybdenum, zinc, and lead for markets focused on the electrification transition. Capstone Copper's operations span the United States, Mexico, and Chile, with a primary emphasis on low-cost copper production supported by by-product credits from precious and base metals. In recent developments, the company completed first copper concentrate production from the $870 million MVDP in June 2024, achieving commercial production in September 2024 and full milling rates by year-end; sanctioned the Mantoverde Optimized (MV-O) brownfield expansion in Q3 2025 to increase sulphide concentrator throughput from 32,000 to 45,000 tonnes per day for incremental annual copper production of approximately 20,000 tonnes and 6,000 ounces of gold while extending mine life to 25 years at a capital cost of $176 million, with construction to commence for tie-in in Q3 2026; entered into a strategic investment agreement with Orion Resource Partners in October 2025 for up to $360 million in cash consideration in exchange for a 25% interest in a joint venture holding the Santo Domingo and Sierra Norte projects, including $225 million upon a positive final investment decision expected in H2 2026, $75 million matching contribution, and up to $60 million contingent consideration tied to value-enhancing milestones such as cobalt circuit feasibility and permitting, while retaining a buyback option post-commercial production; acquired Sierra Norte in July 2024 and signed an exploration option agreement with ENAMI for over 18,000 hectares surrounding the property; reported positive Phase 1 exploration results at Mantoverde extending mineralization north of the pit with Phase 2 drilling to commence in Q4 2025; and advanced district-scale growth opportunities including Mantoverde Phase II, Mantos Blancos Phase II concentrator expansion to 27,000 tonnes per day, Pinto Valley district consolidation, and cobalt processing synergies across the Mantoverde-Santo Domingo district.
