Chuquicamata (/ tʃ uː k iː k ə ˈ m ɑː t ə / choo-kee-kə-MAH-tə; referred to as Chuqui for short) is the largest open pit copper mine by excavated volume in the world. [citation needed] It is located in the north of Chile, just outside Calama at 2,850 m (9,350 ft) above sea level, 215 km (134 mi) northeast of Antofagasta and 1,240 km (770 mi) north of the capital, Santiago.

The Chuquicamata Copper Deposit — Chile SpringerLink

Chuquicamata is the largest copper deposit in the world and would demand our attention for no other reason, but it has many interesting geological features as well. It is a ‘porphyry-copper’ type deposit with a rather atypical pattern of alteration, and the example of the type with best development of ‘oxide-ore’.

Major Mines Projects Chuquicamata Mine

Apr 19, 2015  These copper deposits are known as “porphyry copper” deposits (due to their association with a porphyritic intrusions). Most of these formed during the Eocene to Miocene in Chile (~ 43 to 5 Ma; Mpodozis and Cornejo, 2012). Examples of some of the most giant porphyry copper deposits are Chuquicamata and Rio Blanco-Los Bronces.
