Porphyry deposits host the most of world’s indicated Cu and Mo resources and are major sources of critical metals including Au, Ag, PGE, W and Re. The Sierra Gorda Paleocene-Eocene Cu-Mo deposit, located on the Atacama Desert in Northern Chile, can be identified as porphyry-type in terms of contained metals (Cu grade less than 0.5%, Mo grade up to 0.02%), mineralization (disseminated or stockwerk vein-hosted hypogene sulphides), structural controls (stockwerks and hydrothermal breccia bodies), and genetic relation to an intermediate calc-alkaline intrusion (monzodiorite intrusion in volcanic country rocks). Three main centres of mineralization are associated with the intrusive body and genetically connected with spatially evolved hydrothermal alteration. With target annual production of 220 k tones of Cu and 55 k tones of Mo, Sierra Gorda is the largest open-pit project of the major Polish metal mining company KGHM Polska Miedź.
