Chile's Mantoverde Mine Workers Threaten Strike from Dec 29 if Contract Talks Fail

Published: Dec 26, 2025 09:41
Workers at Capstone Copper’s Mantoverde mine in Chile are prepared to go on strike if mediation for a new labor contract fails, with a potential walkout set to begin on December 29. The 645-member union turned down a contract proposal in mid-December, clearing the way for a strike. An initial five-day government-mediated negotiation period is currently underway and may be extended by another five days if both parties agree.
