Why it may matterVerify against the original reporting

Near-term cash-flow and margin pressures from Caserones downtime; potential investors may reevaluate 2026 earnings. Historical weather-related mine outages have briefly pressured stock performance; the magnitude will depend on the speed of recovery and changes to the ramp-up trajectory.

What happened, with direct paths to the underlying reporting

Lundin Mining updated its Chile operations after a second winter storm, lowering Caserones’ 2026 copper guidance to 120k–130k tonnes and raising cash costs to $2.15–$2.35 per lb. Consolidated copper production guidance remains 300k–325k tonnes with cash costs of $1.95–$2.15 per lb, while Candelaria stays on track.
