Pascua Lama project, Atacama Region, Chile

Open-pit gold-silver-copper project owned (as of 2007) by Barrick Gold Corp. Mineralization, both disseminated and of stockwork type, is hosted in late Paleozoic and mid-Tertiary intrusive and volcanic rocks, extending across the border into Argentina too (http://www.mindat.org/loc-156889.html). Located at around 4,600 meters elevation.

The project is controversial because of its economic and environmental consequences.
