The Centinela Project is a large-scale copper mining operation located in Chile’s Antofagasta Region, approximately 1,350 kilometres north of Santiago. Situated within one of the world’s most productive mining districts, the operation exploits both sulphide and oxide ore bodies, making it a cornerstone asset in Chile’s copper industry.

The project produces copper concentrate containing gold and silver by-products, molybdenum concentrate, and copper cathodes through a combination of conventional milling, flotation, and solvent extraction/electrowinning (SX/EW) processes. As a key component of Antofagasta Minerals’ portfolio, Centinela plays a vital role in supplying critical metals to global markets while supporting the company’s long-term growth and operational excellence strategy.
