A copper mine in southern Peru that took decades to complete environmental assessments has been contaminating local watersheds with harmful metals, critics say. In its first few years of operation, the mine has allegedly endangered wildlife, threatened the local economy, and created health concerns in communities. Developers of the Quellaveco mine in Peru’s Moquegua department spent more than 20 years conducting and revising environmental assessments to responsibly extract copper and molybdenum, a metal used in industrial alloys.

The mine is operated by Anglo American Quellaveco S.A., a subsidiary of British mining company Anglo American. The company received its first environmental impact assessment approval for the project in 2000, but then spent another two decades revising it and finishing technical permitting and negotiations with local communities.

Residents around the Quellaveco mine said they wanted to avoid the problems that had emerged from earlier large-scale…This article was originally published on Mongabay
