Exploration: 1,052 m of 0.29% Cu including 480 m of 0.42% Cu (AZ22174)
Delineation: 236 m of 1.39% Cu and 0.19 g/t Au including 42 m of 2.78% Cu (AZ23191)

“Strong team performance is accelerating our Los Azules program in 2023,” commented Michael Meding, Vice President and General Manager of McEwen Copper. “Exciting results in hole AZ22174 highlight the potential of exploration to create additional value for McEwen Copper, and continuity of mineralization in the infill program is de-risking our mineral resource.”

TORONTO, March 06, 2023 (GLOBE NEWSWIRE) -- McEwen Copper Inc., 52%-owned by McEwen Mining Inc. (NYSE: MUX) (TSX: MUX), today reports new copper values over extensive widths resulting from infill and step-out exploration drilling at its Los Azules Project. Los Azules is a large porphyry copper-gold-silver deposit with considerable growth potential, where its ultimate depth and lateral extent remain to be determined.
The Los Azules project, located in the San Juan province, Argentina, has many attributes comparable to world-class copper-gold deposits in South America. Table 1 provides a summary of the assay results for the two drill holes for copper (Cu), gold (Au) and silver (Ag).


Exploration: 1,052 meters (m) of 0.29% Cu including 480.0 m grading 0.42% Cu (AZ22174), which is coincident with a prominent deep geophysical anomaly and showcases the potential to meaningfully expand Los Azules through exploration.

Delineation: 236 m of 1.39% Cu and 0.19 g/t Au, including 42 m of 2.78% Cu (AZ22191) demonstrates strong internal continuity of the high grade mineralization from the current infill program and further de-risks our geological model.

Over 13,500 m of drilling were completed between January and May in 2022. Activity at Los Azules restarted in October, focused on completing a drill program covering over 25,000 m in 75 new holes, designed to:

Increase infill drilling to upgrade the Cu, Au and Ag resource classification to measured and indicated, leading to improved geological and economic estimates in a planned 2024 Feasibility Study (FS).

Provide metallurgical, hydrological and geotechnical data to facilitate mine design.

Demonstrate extensions of Los Azules to the North, South and at depth.
From October to the 3rd week of February, a further 16,900 m in 66 holes have been completed for the current program, making this the most extensive annual drill campaign in the history of the project. A more comprehensive update of results from the current campaign will be released soon.
