TORONTO, May 04, 2023 (GLOBE NEWSWIRE) -- McEwen Copper Inc., 52%-owned by McEwen Mining Inc. (NYSE: MUX) (TSX: MUX), today reports the latest assay results from Los Azules, where an ongoing infill drilling program continues to delineate copper mineralization in the core of the deposit. Infill drilling serves several purposes: providing better data density to upgrade confidence in the mineral resources, providing material and data for metallurgical, geotechnical, and hydrological studies, and potentially defining higher grade mineralization by drilling inclined holes across vertical structures (such as breccias).

Key Points: 
  • Below the Enriched zone, the Primary (or Hypogene) zone is formed by ascending copper-rich thermal fluids having a much deeper magmatic origin.
  • The green line indicates the pit floor of the 30-year pit shell from the 2017 NI 43-101 Preliminary Economic Assessment (PEA).
  • In addition, the laboratory performs its own internal QAQC checks, with results made available on certificates for Company review.

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).

Key Points: 
  • The results from hole AZ22174 reinforce our belief that the deposit continues to be open at depth and to the North and represents a sizeable opportunity.
  • The sub-interval of 26 m grading 1.46% Cu includes early mineral porphyry and quartz veinlets that also typify the core of Los Azules.
  • Delineation drilling continues at Los Azules with a focus on upgrading to Measured mineral resources the Enriched zone as shown on Section 37 in Figure 2.
  • In addition, the laboratory performs its own internal QAQC checks, with results made available on certificates for Company review.
