SnapshotIn 2019, after 104 years of operation, the world’s largest Chuquicamata openpit mine became acutting-edge underground mine, equipped for 21st century environmental and safety standards.

Chuquicamata Underground is being mined on three levels located at different depths. The projects underway are the "Mining Works and Infrastructure for Operational Continuity" on Level 1, which is in operation.

By December 31, 2024, phase I of the continuity infrastructure project was 73% complete, while plans for the second phase of infrastructure continuity are undergoing feasibility studies. Prefeasibility studies are also underway for a new mine level to assess its development potential.

In 2024, construction of a desalination plant to supply industrial seawater to Chuquicamata and other northern operations reached 66% completion, with startup expected in early 2026.

Summary:

The Chuquicamata district includes the Chuquicamata and Radomiro Tomic megadeposits, the exotic copper deposit Mina Sur, the newly developed Ministro Hales mine (formerly known as Mansa Mina) located 5.5 km south of Chuquicamata, and the deposits of the Toki cluster (Toki, Genoveva, Quetena, Miranda, and Opache) located about 15 km SSW of Chuquicamata.

The deposits of the district are located in the Late Eocene–Early Oligocene (43–31 Ma) porphyry copper belt that extends for about 1,400 km, from 18°S to 31°S (Sillitoe 1988; Sillitoe and Perelló 2005). The rocks in the area range in age from Paleozoic to Tertiary. The main structural feature observed is the West Fault, which is part of the Domeyko Fault System (Boric et al. 1990; Dilles et al. 1997) and divides the district in two domains: an eastern domain and a western domain.

The Chuquicamata deposit is a porphyry-type ore body. The most important feature of the ore body is a north-south regional fault, the west fissure fault, which cuts the ore on the west side and creates a sharp limit on the deposit. An oxide ore zone was a large part of the deposit and has been almost totally mined out. The mine contains a supergene enrichment layer (a redeposit of copper, by natural forces, from higher to lower layers), which has a thickness of almost 800 meters near the center of the mine. Five kilometers north of Chuquicamata, the ore body narrows and merges with the Radomiro Tomic ore body
