Antofagasta approved expansion of the Centinela mine in December 2023, as well as the continued development of the Esperanza Sur pit and the deployment of autonomous vehicles at its sites.  

The company also plans to open a desalination plant for its Los Pelambras mine. 

On top of its industry expansion plans, Antofagasta aims to invest $40-$50m a year on maintenance of its projects in Peru, the US and Canada.  

In 2023, Antofagasta acquired a 19% stake in the Minera Buenaventura mine in Peru.  

The company’s projects in the US, however, have suffered a significant setback after the Biden Administration cancelled two long-standing mineral leases for Antofagasta’s subsidiary Twin Metals. The Administration also imposed a 20-year mining moratorium on the surrounding area in northeast Minnesota. 

Antofagasta is the second largest mining company in Chile after Codelco, which is owned by the Chilean Government.  

According to Mining Technology’s parent company, GlobalData, Chile produced 5240.4 thousand tonnes of copper in 2023, the highest amount globally.
