Scrap gold and silver prices fall, Platinum unchanged on Index, 1st June, 2015

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.

North Copper stated at its earnings briefing on May 22 that since 2025, the contributions of sulphuric acid and precious metals businesses to the company's operating performance had increased significantly. Going forward, the company would further adjust its copper raw material structure, increase the procurement proportion of gold concentrates, and boost gold production. Meanwhile, it would increase R&D and capacity for mid-to-high-end copper strip products, raise the production proportion of treated foil in rolled copper foil, and continuously enhance the added value of copper processing products.
