What Minera Los Pelambres does

Minera Los Pelambres is a large-scale open-pit copper mining operation located in the Coquimbo Region of Chile, approximately 240 km north of Santiago, operating as a wholly-owned subsidiary of Antofagasta Minerals S.A. (AMSA), which is itself a subsidiary of London-listed Antofagasta plc controlled by the Luksic family. The mine began operations in 1992 and currently runs at a nominal capacity of 175 ktpd, producing copper concentrate (with gold as by-product) and molybdenum concentrate through a milling and flotation process. It ranks among the 10 largest copper producers globally and, together with Centinela, accounts for approximately 80% of Antofagasta Minerals' copper output.

The operation is anchored by significant infrastructure investments totaling more than US$5 billion across the INCO project (US$2.2 billion, completed 2022), the PAO Operational Adaptation Project (approximately US$2 billion, in peak construction as of 2026), and the desalination platform financed via the Project Mallupai / DSWS SpA special purpose vehicle (US$1.55 billion BBB+ US private placement). Technical differentiation includes the first desalination plant for mining in central Chile (400 l/s capacity, scaling to 800 l/s), an 83-85% water recirculation rate among the highest in the industry, and an Integrated Operations Management (GIO) system that enables remote real-time operations management. The mine's operational life has been extended to 2053 through the EVU project.

Commercially, Minera Los Pelambres sells copper concentrate, molybdenum concentrate, and gold by-product to global industrial customers at prevailing commodity market prices through offtake agreements, with products transported via concentrate pipeline (concentraduct) to port facilities for export. Pricing is determined by global commodity markets with no consumer-facing pricing tiers. Revenue concentration is structurally diversified across the global copper market rather than named enterprise accounts. The operation contributes approximately 25% of Coquimbo Region GDP and 73% of its exports, with social programs (Fundación Minera Los Pelambres, founded 2003) and ESG certifications (The Copper Mark, ICMM membership) supporting its social license to operate.
