Fresh opposition to Southern Copper’s billion-dollar project in Peru

According to Mining News Pro - Farmers from the Tambo Valley in central Arequipa began an indefinite strike on Monday to protest the imminent construction of the open-pit copper mine. They also blocked a portion of the country’s main coastal highway to obstruct access to the mine site.

While the blockade has now been lifted, opponents continue to press the government to revoke the construction permit awarded to Southern Copper only a week ago, local paper El Comercio reports.

Tia Maria has been derailed twice – in 2011 and 2015 – because of deadly protests by farmers who fear the proposed open-pit mine will damage crops and affect water supplies in the southern region of Arequipa.

The protests against the massive project echo other fights between anti-mining groups, farmers and mining companies in Peru over the last few years. Most of them centre around who gets to use precious water supplies in the country’s bone-dry areas.

Southern Copper estimates that Tia Maria will produce 120,000 tonnes of copper a year during an estimated 20-year lifespan.
