what happened
Workers at Antofagasta's Centinela copper mine in Chile voted on Saturday to approve a new collective bargaining agreement, ending a strike that had threatened copper output at a time of tight global supply, according to Seeking Alpha.
Two Centinela unions, representing about 700 workers, had walked out on October 7 after regular negotiations failed to bridge gaps over pay and benefits. Days earlier, more than 1,000 supervisors and staff at BHP's Escondida, the world's largest copper mine, reached a last-minute deal that averted a walkout.
Antofagasta said earlier last week that it had kept production at normal levels, so the strike had no negative effect. The mine produced 240K metric tons of copper in 2025.
why it matters
Both settlements reduce the risk of supply disruptions in copper, a market already short of metal. For miners' shares, it removes part of the operational risk premium.
market impact
Copper: lower supply-disruption risk removes some price support for the metal
