Union members at Antofagasta's Centinela operation endorsed a fresh pay package on Saturday, according to messages from a union representative. The walkout began on Oct. 7 after routine bargaining failed to bridge differences on wages and benefits, and it will conclude when the agreements are executed.
Centinela's vote removes a production risk at a time when global copper availability is tight. The site turned out 240,400 metric tons in the prior year and is one of four mines Antofagasta runs in Chile. The timing also follows a separate deal just days earlier at BHP Group's Escondida, where more than 1,000 supervisors and staff accepted a last minute agreement that prevented a strike at the world's largest copper mine. Together, the two outcomes dial back concerns about supply interruptions even as producers strain to meet rising demand.

Chile's sector still faces hurdles. Output in the top producing country has been hit by accidents, harsh weather and other operational issues, keeping global supply constrained. Meanwhile, tariff risk is pulling metal into U.S. storage, and end use in power networks and data centers is accelerating, with prices hovering near records. In plain English: two labor deals lower near term disruption risk, but the supply backdrop remains tight against firm demand.
