Pascua Lama Mine, Chile

Following the Chilean Supreme Court resolution, the Pascua-Lama mine is temporarily interrupted since 2013.


Canadian multinational corporation Barrick Gold proposed, via its Chilean affiliate Minera Nevada, a mining project called Pascua Lama to the Chilean government for the extraction of gold, silver and copper concentrate. Pascua Lama is located in a valley of the Andes at an altitude of 4,500 m (14,800 ft). The project is bi-national since the exploitation site is located on both sides of the Argentinian-Chilean border. The two countries signed a special agreement in 2007 which diminished their sovereignty powers, in order to favor and facilitate the extractivist activities. Local residents, who live off of the land, worry about the effects of the mining on such a fragile ecosystem and the mining companies plan to displace the glaciers. Along with NGOs and environmental associations, they strongly oppose the project. In Argentina too, the local population mobilized against it. The mine’s operations are interrupted since September 25th 2013, the day the Supreme Court of Chile’s resolution suspended the mining project between the two countries because of the company’s serious environmental wrongdoings. It is not a permanent decision since the Supreme Court gives to the mining multinational the possibility to reopen once complying to the environmental requirements.
