Global Copper Mine Production Flat in Q1 2026, Indonesia's Grasberg Mine Sees Sharp Decline
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.
