Chile Copper Mine Strike Looms After Contract Rejection
28 Sep
Summary
- Two unions at Centinela mine rejected contract offers.
- A strike is now a possibility at the copper mine.
- The mine is operated by Antofagasta Minerals in Chile.
Workers at the Centinela copper mine in northern Chile have rejected a collective contract offer from their employer, Antofagasta Minerals. The decision was made by members of two unions on Monday, September 28, 2026, and signals a potential strike. This development comes after contract negotiations failed to reach an agreement acceptable to the workers.
The Centinela mine is a significant operation for Antofagasta Minerals, located in a key mining region of Chile. The rejection of the offer means that labor action, including a strike, is now a distinct possibility, which could impact copper production from the facility. Further details regarding the next steps for the unions and the company are expected.
