“…Most of the new discoveries are in Miocene-Pliocene permissive tracts, although Eocene-Oligocene and older porphyry belts continue to host new discoveries, including the tract that hosts the world class Chuquicamata deposit (Figure 2b). The most well-endowed porphyry belts in Argentina are Miocene and the southern extension of the Miocene-Pliocene belt that hosts the giant El Teniente deposit in Chile into Argentina is a prospective underexplored region [14].…”

“…Part of the Andes assessment was revisited in an overview of porphyry copper deposits in the Central Andes of Argentina [14]. That study identified 10 metallogenic belts for porphyry copper deposits that modified the USGS tracts and incorporated new data, updated the known resources for Argentina, and recalculated undiscovered resources in the revised metallogenic belts using the same methods.…”

“…In addition to checking for subsequent resource updates to the 2005 and 2008 data, resource data for discoveries in the Andes through 2020 were compiled from NI 43-101 technical reports, company websites, the online Porter Geoconsultancy database and references therein [16], commercial databases, and journal articles documenting new deposits, e.g., [14,17].…”

A mineral resource assessment of porphyry copper deposits in the Andes Mountains of South America was done in 2005 in cooperation with geological surveys in South America. The study identified 590 million metric tons (Mt) of copper in identified resources. Continued exploration and development in the region over a 15-year period provide an opportunity to compare the predicted assessment results with new discoveries and resource growth in previously known deposits. The 2005 assessment estimated that 145 undiscovered deposits could contain a mean of 750 Mt of copper. The actual number of deposits increased (2005 to 2020) from 69 to 120 and the amount of identified copper resources increased from 590 Mt to 1600 Mt. Although most of the new deposits and copper resources are concentrated in Miocene-Pliocene and Eocene-Oligocene mineral belts, new deposits have been discovered in Jurassic and Cretaceous mineral belts. Resource growth in porphyry copper deposits known in the Andes in 2005 (1100 Mt copper) exceeds copper resources in new discoveries since 2005 (490 Mt copper) by a factor of 2.
