Cerro San Pedro Gold and Silver Mine

Metallica Resources Inc.

When Metallica arrived in Cerro de San Pedro in 1995 to build an open pit mine, local residents, human rights organizations and environmental groups formed the Broad Opposition Front (FAO) to halt the operation that they say would destroy their 400-year old town.  The company’s own environmental impact assessment reveals that if built, the mine would require the relocation of the community and would cause “significant adverse” impact to the area’s only aquifer.[1] The latter is of particular concern.  Water is extremely scarce in the State of San Luis Potosi and the National Water Commission of Mexico reports that it is already being exploited at an unsustainable rate.[2]  Local residents, whose property has been adversely affected by Metallica’s exploration activities, have sued the Government of Mexico over its decision to issue the company a permit.[3]
