Mantoverde expansion permit clears path for Capstone’s MV-O project

Capstone Copper

Mantoverde expansion permit clears Capstone’s path to build the MV-O project. The Atacama commission granted the DIA, enabling immediate pre-construction steps. The Mantoverde expansion permit boosts capacity and extends the mine life.

Throughput, mine life, and incremental copper

Mantoverde currently produces 120,000 tonnes of copper sulfides each year. MV-O lifts concentrator throughput from 32,000 to 45,000 tonnes per day. The expansion adds about 20,000 tonnes of copper annually. Mine life extends from 19 to 25 years under MV-O. Capex totals about $150 million, according to the plan.

Permitting status and construction timing

The DIA is the only major permit required for MV-O. Capstone can start construction after final regulatory approvals. Capstone owns 70% of Mantoverde in Chile’s Atacama region. The Mantoverde expansion permit provides schedule certainty for contractors. The project supports more efficient sulfide processing at scale.

The Metalnomist Commentary

A modest capex for meaningful copper growth is strategically attractive. Execution risk concentrates in schedule discipline, power reliability, and ramp efficiency. Watch how quickly Capstone advances procurement and early works.
