Two unions at Chile’s Centinela copper mine decided to strike.

Chile is the world’s largest copper producer, and strike risk had been supporting global prices.

Wage talks with Antofagasta Minerals ended without a deal, and the Minera Esperanza and Distrito Centinela unions rejected further negotiations.

Output was already constrained by operational disruptions, natural events and declining ore grades.

No report gives the strike’s duration, headcount or lost copper output.
