Antofagasta plc is a major international copper producer with its principal operations concentrated in Chile. The company's business is structured into two main divisions: Mining and Transport. The Mining division operates four key assets—Los Pelambres, Centinela, Antucoya, and Zaldívar—which collectively produce hundreds of thousands of tonnes of copper annually, alongside significant volumes of gold, silver, and molybdenum by-products. The Transport division, operating as Ferrocarril de Antofagasta a Bolivia (FCAB), provides essential rail and truck freight services to mining customers across the Antofagasta region. Originally founded in 1888 as a railway operator, the company diversified into mining in the 1980s under the control of the Luksic Group. Today, Antofagasta is a constituent of the FTSE 100 Index and is recognized for its focus on sustainable mining practices, including the transition to renewable energy across its operations.
