Chile's Centinela copper mine experienced its first-ever strike on October 9, following the breakdown of mandatory mediation talks between the company and the miners' union. Natalia Corfield, Head of Latin America Corporate Credit Research at JPMorgan Chase, warned that if the labor dispute persists, the mine's output and the company's performance could be "very significantly" impacted. Centinela is a core copper asset of Antofagasta, projected to produce 240,400 tons of copper in 2025, accounting for over 35% of the company's total output. The strike occurred as London copper futures prices were approximately $14,475 per ton, slightly below historical highs, adding further uncertainty to the tight global copper market.
