Peru’s environmental watchdog said on Sunday it was investigating a tailings spill from a unit of Southern Copper Corp, one of the world’s largest copper producers, into a river in an area that has been inundated by heavy rains.
The Agency of Evaluation and Environmental Enforcement (OEFA) said the spill occurred in the waste deposit area of the Cuajone mining operations of Southern Copper, located in the Moquegua region about 860 km southeast of Lima.
