Capstone Copper stock faces lower 2026 output after crusher delay

- Capstone Copper expects the Pinto Valley primary crusher to return in mid-December after additional maintenance.
- The company sees a potential 5,000-tonne impact on 2026 copper production from the extended downtime.
- A truckers' strike in Chile threatens shipments and supplies, while Mantoverde and Mantos Blancos remain unaffected so far.
Capstone Copper said on Thursday, November 12, that additional maintenance at its Pinto Valley primary crusher will delay recommissioning until mid-December. The company expects temporary mobile crushing equipment to support a partial concentrator restart in mid-November, with throughput of up to 40,000 tonnes per day, according to its November 12 news release.
Pinto Valley restart delayed
The extended maintenance is expected to reduce Capstone Copper's 2026 copper production by about 5,000 tonnes, depending on the timing of the interim restart and the crusher's return to service. The company therefore lowered the bottom end of its consolidated 2026 production guidance to 195,000 tonnes from 200,000 tonnes, while the release did not change the upper end of the range.
Chile strike adds logistics risk
A national strike by Chilean trucking associations and a civic movement creates additional risk for concentrate and cathode shipments, as well as deliveries of fuel and sulphuric acid. Capstone said production at Mantoverde and Mantos Blancos remained unaffected when it issued the update, supported by advance measures and on-site storage.
