Copper supply risks ease as miners do deals in biggest supplier

Chile’s copper-mining industry is emerging from an intense period of wage negotiations, signaling a diminished risk of further disruptions in a country that accounts for a quarter of supply.

Over the weekend, about 300 striking workers at a Lundin Mining-operated mine went back to work. A week earlier, the main union at the giant Escondida mine run by BHP Group ratified a labor pact following a three-day stoppage. Antofagasta reached an early wage deal with the main union at its Centinela facility, completing the firm’s talks for the year.
