- Antofagasta’s Copper Output Drops 9.5% in First Half on Lower Ore Grades
Antofagasta’s copper production declined 9.5% year-on-year to 285,000 tonnes in H1 2026 due to lower ore grades, pipeline maintenance at Los Pelambres, and reduced throughput at Centinela concentrators. The drop reduced Chile’s export revenue and government royalties, indicating structural supply constraints.
