Los Bronces Integrated Project (LBI)

Description: The Los Bronces Integrated Project (LBI) copper project entails the adaptation and optimization of the current Los Bronces mining plan, through the development of three new exploitation phases that are located east of the current pit, another to the west and an underground phase located to the south. The east and west phases are mostly located in the Cordillera region of the Metropolitan Region, while a smaller part is located in the Valparaíso region. The underground phase is approximately 5km south of Los Bronces, below the surface of the northern end of the Fundo Yerba Loca Nature Sanctuary, at an average depth of approximately 660m. LBI has been designed to meet sustainability criteria that are related to the non-involvement of glaciers, surface and underground water resources, biodiversity and not having contributions of sedimentable particulate material that may affect discovered glaciers. The project will require an average labor force of 2,000 people during construction and another 2,000 in the operation phase. The project is located in the cordillera area of the Metropolitan Region, (Santiago province, Lo Barnechea commune, and Chacabuco province, Colina commune) and in the Valparaíso Region (Los Andes province and commune), about 65 km northeast of the city of Santiago.
