Copper mine Quellaveco on the Asana river, Peru

A four year mega-project for the diversion of the Asana river is about to start. The agreement reached in 2012 hasn't appeased concerns for the mining detrimental consequences.


The Quellaveco Company envisaged the diversion of the Asana river, one of the Moqueguas largest tributaries, in order to dispose waste from its mining operations, causing contamination of aquifers and land. Resident farmers opposed the project, refused to sell their land to the company and demanded respect for their rights.
