Los Pelambres Mine is one of the world's largest copper producing sites, located in the Choapa Province of the Coquimbo Region, situated at an altitude of 3,600 meters in the Andes Mountains. This open-pit operation targets a massive porphyry copper deposit that also yields significant quantities of molybdenum and gold as byproducts. Commercial operations commenced in 1999 following an extensive infrastructure buildup, which included a 120-kilometer concentrate pipeline reaching the Pacific coast. Operated by Antofagasta Minerals, the facility has recently pioneered large-scale seawater desalination to mitigate freshwater usage from local river basins. With an annual production capacity exceeding 300,000 tons of copper, the mine remains a cornerstone of the Chilean economy and a vital link in the global supply chain for industrial metals. The logistical challenge of operating at high altitude is matched by the site's commitment to modern environmental standards and community integration.
