Workers Strike at Chile's Mantoverde Mine Threatens Copper Production
A strike by 645 workers at Capstone Copper's Mantoverde mine in Chile has reduced operations to 30% capacity. The disruption threatens the mine's 2025 production target amid global copper supply constraints.
洞察:
A workers' strike at the Mantoverde mine in northern Chile, operated by Capstone Copper Corp , has significantly disrupted operations. The strike, initiated by Union No. 2 last Friday following unsuccessful collective bargaining negotiations, has reduced the mine's output to just 30% of its capacity. This operational slowdown is exacerbated by the rapid depletion of stockpiled inventory, which is expected to run out within days, directly threatening the mine's 2025 production target of 29,000 to 32,000 metric tons of copper cathodes.
The strike involves 645 workers, representing approximately 22% of Capstone Copper's total workforce, and underscores a critical moment for the company. The union's demands, which reportedly would have cost the company around $500,000 annually, were not met, leading to the current impasse. Despite the breakdown in negotiations as of Wednesday, January 7, 2026, Capstone Copper has expressed openness to further discussions to resolve the dispute.
