No breakthrough in talks at Antofagasta's striking Centinela copper mine, unions say

Negotiations between Antofagasta Minerals and two ​striking unions at Chile's Centinela ​copper mine showed no ‌progress on ​Thursday, while three workers marked their seventh day on a hunger strike.

The Distrito Centinela and Minera ‌Esperanza unions, which together represent more than 700 workers, began the walkout on October 7 after contract talks collapsed. The sides returned to the negotiating table on ‌Tuesday in an effort to resolve the dispute.
