Chile investigates Antofagasta’s Los Pelambres Mine after rainwater discharge

Antofagasta Minerals, a Chilean copper mining company, said on Thursday that its flagship mine Los 'Pelambres is safe following an investigation by Chile's environmental regulator into a water discharge incident caused by extreme weather.

On Wednesday, the regulator said that Antofagasta released water into the Pupio Waterway from a drainage pool after heavy rains caused an?avalanche near the site. Antofagasta has said that the controlled release of water from two pools downstream the tailings?dam?wall was part of its water management system. Water from the tailings dam was channeled to the Pupio stream whose flow had already increased significantly because of rain. The company reported that the tailings pond was "stable and in accordance with its design parameters and safety parameters with no risk to people or surrounding?environment." * The regulator stated that it will continue to evaluate whether any further action is needed. Chile has been hit by heavy rains?from the north-central region to the south causing flooding, road closures, and home damage. * Copper mines are usually prepared for winter with contingency plans. However, the intensity of the storm has forced some to reduce their activities.

*?Los Pelambres is the largest copper mine in Antofagasta, located in Chile's Coquimbo region.
