The Rajo Inca project will make it possible to extend the operation of the Salvador Division for 47 years, given the depletion of resources currently in exploitation. At the end of 2022 year, physical progress was 42.6%. The development of the works has been affected by the impact of the pandemic and difficulties in the supply chain. |

Codelco, as a productive business, grouped all the deposits (The El Teniente, Andina, Exotica, Chuquicamata and El Salvador) into a single mining, industrial and commercial corporation.
Codelco Corp. operates seven mine sites (known as “divisiones”): Chuquicamata, Ministro Hales, Radomiro Tomic, Gabriela Mistral, Salvador, Andina, El Teniente, in addition to the Ventanas Smelter and Refinery.

Summary:
The Eocene (42 to 41 Ma) El Salvador porphyry copper deposit in the Indio Muerto district, northern Chile (26° 15' S Lat.), formerly thought to have formed at the culmination of a 9-m.y. period of episodic magmatism, is shown by new mapping, U-Pb and K-Ar geochronology, and petrologic data to have formed during the younger of two distinct but superposed magmatic events—a Paleocene (~63 to 58 Ma) and an Eocene (44 to 41 Ma) event. In the district, high-K Paleocene volcano-plutonic activity was characterized by a variety of eruptive styles and magmatic compositions, including a collapse caldera associated with explosive rhyolitic magmatism (El Salvador trap-door caldera), a post-collapse rhyolite dome field (Cerro Indio Muerto), and andesitic-trachyandesitic stratovolcanos (Kilometro Catorce-Los Amarillos sequence).
Precaldera basement faults were reactivated during Paleocene volcanism as part of the collapse margin of the caldera. Beneath Cerro Indio Muerto, where the porphyry Cu deposit subsequently formed, the intersection of two major basement faults and the NNE-striking rotational axis of tilted ignimbrites of the Paleocene El Salvador caldera localized emplacement of post-collapse rhyolite domes and peripheral dikes and sills. Subsequent Eocene rhyolitic and granodioriticdacitic porphyries intruded ~1 4 m.y. after cessation of Paleocene magmatism along the same NNE-striking structural belt through Cerro Indio Muerto as did the post-collapse Paleocene rhyolite ........
