About McEwen Copper

McEwen Copper Inc. holds a 100% interest in the Los Azules copper project in San Juan, Argentina and the Elder Creek project in Nevada, USA.

Los Azules ranked the 8th largest undeveloped copper deposits in the world (Mining Intelligence, 2022). Its current copper resources have increased to 10.9 billion pounds at a grade of 0.40% Cu (Indicated category) and an additional 26.7 billion pounds at a grade of 0.31% Cu (Inferred category) as of the June 2023 Preliminary Economic Assessment (PEA). The PEA estimates a $2.7 billion after-tax NPV8% at $3.75/lb Cu, a low average C1 production cost of $1.07/lb Cu, a 3.2-year payback period, and a 27-year mine life.

A bankable feasibility study (FS) is underway with completion, planned by the end of Q1 2025. Los Azules is being designed to be distinctly different from other copper mines, consuming significantly less water, emitting much lower carbon and progressing towards carbon neutral by 2038, and being powered by 100% renewable electricity once in operation.
