Antofagasta's Centinela Copper Mine Strike Ends After Deal With Unions

3-line summary

• A strike at Antofagasta's Centinela copper mine in Chile that began October 7 and lasted more than a week ended Sunday after the company reached a new collective-bargaining agreement with the Distrito Centinela and Minera Esperanza unions, which together represent about 700 workers, Reuters reported; 94.49% of participating union members voted to approve the deal.
• The unions had demanded equal benefits regardless of union affiliation after talks broke down, triggering the walkout; three workers staged a hunger strike during the standoff, and the dispute had helped support copper prices alongside supply risk from a threatened supervisor strike at BHP's Escondida mine.
• Antofagasta said it kept production at normal levels through the strike and avoided a negative impact; the Centinela mine produced 240,400 metric tons of copper in 2025. The report did not detail the agreement's wage or working-condition terms.
