en.Wedoany.com Reported - Compañía Minera Doña Inés de Collahuasi SCM has submitted an Environmental Impact Statement (DIA) to the Chilean Environmental Assessment System (SEIA) for the "Modification of Waste Rock Extraction at the Rosario Open Pit, New Quarry at Ujina, and Adjustment of Tailings Pumping System, Collahuasi Cordillera Mine" project, with a planned investment of $345 million. The project aims to ensure the continuity, efficiency, and operational safety of the mine, as well as to safeguard processes related to the Tarapacá Region and Chile's national production chain.

This project involves operational adjustments and auxiliary facility construction for the previously environmentally approved "Collahuasi Infrastructure Development and Production Capacity Improvement" project. Specific measures include restoring the waste rock extraction rate at the Rosario Open Pit to achieve approved production levels, adding a quarry in the Ujina area to supplement materials needed for the main tailings dam construction, and adjusting the placement of components in the tailings pumping system within the operational area.

All works will be carried out in the Cordillera area of the Collahuasi mine, located in the town of Pica, Tarapacá Region, within a developed and previously assessed operational zone.
