Chuquicamata - Wikipedia

"Chuquicamata clearly belongs to the broad class of porphyry copper deposits. Practically the entire Chuquicamata orebody is hosted by the Chuqui Porphyry Complex, made up of East, Fine Texture, West and Banco porphyries." These Cu-Mo porphyry systems formed during the Eocene-Oligocene and exhibit classic "zoned alteration-mineralization features."
