Los Azules is an advanced-stage porphyry copper exploration project in the San Juan pro-mining province of Argentina. The project is located approximately 80 km west-northwest of the Calingasta town and 6 km east of the border with Chile, at 3,500 m elevation in the Andes Mountains.
Los Azules is a large high-grade open pit copper project with significant further growth potential. According to the project's updated Preliminary Economic Assessment (PEA) completed in 2023, Los Azules is anticipated to produce an average of 322 million pounds of copper cathode annually over a 27-year Life of Mine (LOM), with competitive cost efficiencies and strong emphasis on minimizing environmental impact.
