Location of the Los Pelambres and El Teniente copper mines in Chile
Los Pelambres mine is a copper mine located in the north-central of Chile in Coquimbo Region . It is one of the largest copper reserves in the world, having estimated reserves of 4.9 billion tonnes of ore grading 0.65% copper.[1]
The deposit was first recognized by Willian Burford Braden in 1920. Production in 2012 was forecast at 390 tons of copper and 28,000 ounces of gold.[2] Los Pelambres Airport , and by a water desalination facility at Los Vilos. A billion-dollar expansion project is underway.[3]
Geology [ edit ]
The Upper Miocene tonalite stock is a north-south oriented oval, 4.5 by 2.4 km in size, which has undergone hydrothermal alteration . The stock intruded into andesitic host rocks. Glaciation during the Pleistocene carved the U-shaped Los Pelambres valley. The head of the valley has the highest concentration of ore in a roche moutonnee . A core of potassium silicate alteration contains the economic copper-molybdenum mineralization . Sulfide minerals include chalcopyrite , bornite , pyrite and molybdenite .[4]
