history

In October 1978 the American J. David Lowell proposed the exploration of the porphyry copper deposits between Chuquicamata in the north and El Salvador in the south of the Atacama Desert . The two companies Utah de Chile Inc. and Getty Mining (Chile) Inc. founded a joint venture in 1979 . On March 14, 1981 the workers encountered a copper-bearing layer 52 meters thick with a copper content of 1.51 percent in the last planned well, Pozo 6, at a depth of 240 meters . Additional boreholes and a shaft were sunk to isolate the deposit and to take additional samples.

The project started in August 1988. In order to get to the copper ore, 180 million tons of overburden were moved. The first ore was processed on November 3, 1990 and delivered at the end of the year. The official inauguration of the Escondida opencast mine took place on March 14, 1991.
