Supervisors at BHP's Escondida copper mine in Chile began a strike on Wednesday, 14 October 2026, after government-led mediation failed to produce a contract agreement before the midnight deadline. Approximately 1,020 workers are involved in the industrial action at the mine, which accounts for roughly 25% of Chile's total copper output. The development was reported by Oilprice and Bloomberg Markets.
Escondida is the world's largest copper mine by output, and the strike directly interrupts production at the site. BHP Group, as the mine's operator, is the primary corporate entity affected by the stoppage. Copper, traded as HG futures on the CME, is the commodity most directly disrupted given Escondida's share of Chilean and global supply.
The strike follows an earlier walkout at Antofagasta's Centinela mine that began 7 October 2026, according to Oilprice, representing concurrent industrial action at two of Chile's major copper operations. Bloomberg Markets reported that BHP had improved its wage offer during a final mediation round on 13 October in an attempt to avert the strike, but negotiations did not conclude with an agreement before the deadline.
