Preliminary data indicated that global copper mine production in Q1 2026 was basically flat, with copper concentrates production declining by 1.1%, offset by a 3.3% increase in solvent extraction-electrodeposition (SX-EW) production.Although global mine production benefited from additional output from capacity ramp-up at projects in several countries, significant declines in copper concentrates production in Chile, the DRC, and Indonesia offset global growth.In Indonesia, copper concentrates production at the Grasberg mine fell by 42%, as the severe mud inflow event that occurred in September last year continued to impact production at the mine.
