At the Cerro Verde district in southern Peru, granodiorite porphyry stocks formed two adjacent porphyry copper-molybdenum deposits that collectively form one of the largest copper districts in the world, with current resources of ~17 million metric tonnes (Mt) of copper. The district is located within the Coastal batholith of western Peru.
Despite the conflict and difficulties that have plagued the mining industry in Peru, it still remains a major player among the world’s mineral producers.
