Supergene enrichment and exotic mineralization at Chuquicamata, Chile

Numerical Modeling of Structurally Controlled Ore Formation in Magmatic‐Hydrothermal Systems

“…Some porphyry deposits also show a structural control of the mineralization, such as the giant Chuquicamata deposit in Chile, where the mineralization has a vertical extent of up to 3 km along a fault zone (Ossandon et al, 2001). However, it is unclear to which degree the current outline of the ore shell at Chuquicamata has been affected by supergene enrichment and later fault displacement, which could mean that the currently mined deposit is only one part of the original hypogene mineralization (Pinget, 2016;Pinget M. et al, 2015;Zentilli et al, 2021).…”
