Collahuasi Copper Mine
Collahuasi (Tarapacá Region, Chile; altitude ~4,400m; Glencore 44%, Anglo American 44%, JX Metals 12%) is one of the world's largest copper mines, producing approximately 560,000-620,000 tonnes/year of copper (concentrate plus cathode). Two open-pit operations — Ujina and Rosario pits — feed the Collahuasi concentrator. Average ore grade approximately 0.95% Cu. Collahuasi is located in the Altiplano at extremely high altitude, creating operational challenges around worker acclimatization and equipment performance. The mine has a dedicated desalination plant on the Pacific coast at Patache (~140km), pumping processed seawater up the Andes for mineral processing — a logistics and energy challenge unique to high-altitude Atacama Desert copper mines. Collahuasi is one of the lowest-cost large copper mines globally due to its scale, strip ratio, and ore grade. Source: Glencore Annual Report 2024; Anglo American Annual Report 2024.
