Metallica Resources was a publicly held Canadian mineral exploration and development company with a geographic focus in the Americas.
This project generated legal challenges and concerted opposition by local citizens and organizations across Mexico and North America.
The concerns were that the open-pit cyanide leach-pit process used by the project would produce irreparable harm to the environment and historical patrimony of this region in Mexico.
Over the years, Mexican courts suspended or revoked various permits for Metallica's Cerro de San Pedro project.
Metallica's corporate goal was to build shareholder value through growth of its existing assets and pursuit of quality investment opportunities.
