Xstrata Tintaya…[part of] Glencore Xstrata, has been fined…for polluting pastureland around its copper mine in Espinar, Cusco...Xstrata Tintaya was found responsible for elevated levels of copper in the soil in an area of pasture…The company had also failed to report the incident to [the environmental authorities] and to provide a report on an investigation. Excessive levels of copper can harm biodiversity and poison livestock. Xstrata Tintaya argued that the copper was naturally occurring and not the result of pollution, but…[authorities] concluded that the metal had spread from water being pumped through a channel by the miner…The dialogue between the company and local communities, established after fatal clashes in 2012 over the mine’s social funding and alleged environmental impact, is due to conclude in March.
