Lundin Mining cuts Caserones copper production forecast due to storms

Lundin Mining copper production Caserones mine Atacama storms mining guidance

Lundin Mining has lowered its 2026 copper production guidance for the Caserones mine in Chile following severe weather. A second major storm in the Atacama region interrupted recovery efforts after an initial storm, causing unplanned downtime at the copper and molybdenum facility.

As a result of the cumulative impact from these unprecedented winter storms, the company revised its 2026 copper production forecast for Caserones from 130,000–140,000 tonnes down to 120,000–130,000 tonnes. Additionally, the projected cash cost for the mine has been adjusted from US$2.05–$2.25/lb to a range of US$2.15–$2.35/lb.

Despite these setbacks at Caserones, Lundin Mining expects the Candelaria operation to meet its annual production targets. The company’s consolidated copper production projection is now estimated between 300,000 and 325,000 tonnes, with a projected cash cost of US$1.95/lb to US$2.15/lb.
