The amount of investment is estimated at 950 million of dollars. Project has a useful life of 20 years according to current bookings, and will annually produce about 5,000 tons of copper concentrates, 615,000 ounces of gold and 18.2 million ounces of silver. Since then, Greenpeace criticized the project in 2005, alleging, among other things, that it will remove part of the three glaciers (Toro 1, Toro 2 and Esperanza) that are located on the area of the mine, in addition to the handling of dangerous toxic substances such as sodium cyanide, and the pollution of waters that make up the basin of the Huasco River; In addition to pose a threat to the traditional agricultural activities in the area. Criticisms were taken into account in modifications to the project that is conducted in the year 2006, which finally allowed his approval. In accordance with the requirements stipulated by the authorities in the approval of the project, the company is obliged to maintain the quality of water established in the baseline – which was determined prior to the start of the project- at a point located approximately 45 km upstream from the nearest community. Along with that, the quality of the water coming out of the mining property, about 30 kilometers downstream from the project and 15 km upstream from the nearest community, must be monitored to maintain the standards that are applied in Chile for drinking water.

Opponents of the project argue that the water supply of 70,000 farmers in the Huasco valley by the release of cyanide, sulfuric acid, and mercury in the Valley would be affected, however, gold mining does not use sulfuric acid, or mercury. And with regard to the cyanide, used a very dilute cyanide solution, which dissolves when it is exposed to air or other oxidizers, breaks down and does not persist. To this is added, that the opponents of the project argue that the water supply of 70,000 farmers in the Huasco valley by the release of cyanide, sulfuric acid, and mercury in the Valley, would be affected. However, gold mining does not use sulfuric acid, or mercury. And with regard to the cyanide, used a very dilute cyanide solution, which dissolves when it is exposed to air or other oxidizers, breaks down and does not persist. It is also said that company has bought the support of farmers with the social assistance and the promises of the 60 million dollars for infrastructure works and that the Treaty of integration and complementation mining was adopted under pressure from Barrick in November 2005, a petition of 18,000 signatures was presented to the Chilean Government by the Anti Pascua Lama front’s fighta coalition of environmental groups. How much damage will cause this to Chileans and those who live on this planet, more when it is known and well expressed it, that bass these millennial glaciers is the treasure of AMERICA that consists of tens of billions of dollars in gold, silver and other metals many omo very well atinachile.c, points out. to extract these metals need to break these glaciers, something that has never been done in the world and make two holes as Chuquicamata, one for extraction and another for waste because mining companies recycle anything.
