The porphyry copper mineralization at Los Pelambres is contained in two contiguous deposits, Los Pelambres (Cu-Mo) and Frontera (Cu-Au), which together constitute the third largest copper concentration (∼36 million metric tons (Mt) Cu) in the Miocene to early Pliocene belt of central Chile.
The El Pachón porphyry copper-molybdenum deposit is located at an altitude of between 3600 and 4200 m in SW San Juan Province, Argentina, some 2 km from the Chilean border, 5 km SE of the Los Pelambres mine in Chile, and 100 km from the Pacific Ocean coast, but 1300 km from the Atlantic Ocean (#Location: 31° 45' 22"S, 70° 25' 37"W). For details of the geological setting see the Los
The Escondida deposit, located in the Andes copper belt of northern Chile, is the third largest porphyry copper deposit in the world with copper reserves of 31.567 millon tons.
Feb 03, 2020· The Los Pelambres porphyry copper deposit, located in the Andean Cordillera of Coquimbo Province, Chile, is related to an Upper Miocene tonalite stock which was passively emplaced into Upper Jurassic-Middle Cretaceous andesitic volcanic and sedimentary strata which constitute a north-south trending monocline.

Oct 17, 2019· Most of the world’s copper is extracted from a type of mineral deposit called a “porphyry copper”. If you’ve seen a picture of a great big open-pit mining operation odds are that it was a porphyry copper deposit. Some of the biggest man-made holes in the ground are porphyry copper mines: Bingham Copper Mine, Utah, and Chuquicamata in Chile, and two of the largest.
Porphyry copper deposits are copper ore bodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic
Understanding Geology of Porphyry Copper Deposits and formations using models around the World. Porphyry Copper Deposits are the largest source of Cu/Mo/Au.
In central Chile, this metallogenic belt includes world class Cu-Mo porphyries, such as: Los Pelambres-El Pachón located 75km north of the Vizcachitas deposit, Río Blanco-Los Bronces located 80 km to south of Vizcachitas and El Teniente located 180 km to the south.
