| Capstone Copper MV-O project |
Capstone Copper has secured key approval for its Mantoverde Copper Expansion, unlocking the next phase of growth in Chile. The $150 million MV-O project extends the mine’s life to 25 years, while boosting annual copper output. This milestone positions the Mantoverde-Santo Domingo corridor as a future copper-cobalt production hub in northern Chile.
Copper Output to Reach 135,000 Tonnes with MV-O Phase
The MV-O project increases concentrator throughput from 32,000 to 45,000 tonnes per day. As a result, copper output will rise by 20,000 tonnes per year, lifting total production to 125,000–135,000 tonnes. The Chilean environmental agency SEA granted the permit following a national review, signaling regulatory confidence in Capstone’s plans. Meanwhile, Capstone’s CEO highlighted MV-O as a cornerstone for establishing one of the world’s largest copper districts.
Long-Term Copper-Cobalt District Strategy in Focus
MV-O marks the second phase of the Mantoverde Development Project, which completed in 2023 with a new concentrator and desalination system. Capstone began commercial production in late 2024 and now targets 250,000 tonnes of copper equivalent annually, when combined with the adjacent Santo Domingo deposit. Capstone owns 70% of Mantoverde, while Mitsubishi Materials holds the remaining 30%. The company plans to publish detailed capital expenditure plans for the MV-O phase shortly.
ScrapInsight Commentary
Capstone’s Mantoverde Copper Expansion reflects a strong long-term supply commitment amid tightening global copper inventories. The swift permit process may spur further investment in Chile’s Atacama region. Strategically, this expansion aligns with decarbonization trends driving copper demand across EV and grid infrastructure sectors.
