Lundin Mining cuts Caserones 2026 copper output guidance to 105,000–115,000 tonnes after winter storms

• Lundin Mining cut its 2026 Caserones copper production forecast by 15,000 tonnes to 105,000–115,000 tonnes amid ongoing weather disruptions.
• Consolidated copper production guidance now stands at 285,000–310,000 tonnes, versus 219,000 tonnes produced year to date.
• Two winter storms disrupted Caserones operations; snowmelt created muddy pit conditions, limiting haulage speeds and ore deliveries.
