Escondida

Escondida is a large open-pit copper mine at 3,100 m (10,200 ft) elevation in the Atacama Desert in Antofagasta Region, Chile. It has for decades been one of world's most productive copper mines and is the mine that leads in copper and gold production in Chile. In 2019 it was estimated that the mine and its ancillary industries generated 2.5% of Chile's GDP. The mine's produce is largely exported to China as ore concentrate that contained as of 2020 an estimate of 4% chalcopyrite, 35% chalcocite and 46% pyrite.
