Los Azules

Los Azules is a large-scale copper development project located in San Juan province, Argentina, in the Andes mountains near the Chilean border. The project is owned and operated by McEwen Copper, a subsidiary of McEwen Mining. Los Azules hosts one of the world's largest undeveloped copper deposits, with measured, indicated and inferred resources totalling several billion tonnes of copper-bearing ore. The deposit is a porphyry copper system, a geological formation that typically yields large tonnages of lower-grade ore suitable for open-pit mining. Los Azules is situated at high altitude in a remote area, requiring significant infrastructure development including roads, power supply and water management systems. The project has undergone preliminary economic assessments and feasibility-level studies to evaluate its technical and financial viability. McEwen Copper has been advancing permitting and environmental approvals through Argentina's regulatory framework, engaging with provincial and national authorities. The project's development timeline and capital requirements are substantial, typical of world-class copper projects in frontier locations. Los Azules is strategically significant for Argentina's mining sector and for global copper supply, as demand for the metal grows with electrification, renewable energy and electric vehicle adoption. The project's progress is closely watched by investors and industry analysts as a potential major new source of copper production in the Americas.
