Escondida

Escondida is a copper mine in the Atacama Desert in Antofagasta Region, Chile. The Escondida deposit is one of a cluster of porphyry coppers in an elongated area about 18 km north-south and 3 km east-west and is associated with the 600 km long West Fissure (Falla Oeste) system, which is in turn associated with most of the major Chilean porphyry deposits. A barren, leached cap, in places up to 300 metres thick, overlies a thick zone of high grade secondary supergene mineralisation of the main orebody, largely chalcocite and covellite, which in turn overlies the unaltered primary mineralisation of chalcopyrite, bornite and pyrite.
