Current Drill Program
Drilling resumed in October 2022. This season's +75 holes and +25,000-meter program is designed to:
Increase drill hole density to upgrade the copper resource classification to measured and indicated to better understand the payback pit design.
Provide metallurgical, hydrological and geotechnical data to facilitate mine design.
Test for potential extensions of the resource to the north, south and at depth to determine how much larger the deposit could be.
Since October, some 11,900 m have been drilled from 46 holes.
"We have transitioned into 2023 with tremendous momentum, backstopped by 9 on-site drills, an active community engagement program and a fully staffed technical team advancing Los Azules towards feasibility," commented Michael Meding, Vice President and General Manager of McEwen Copper. "We are delivering a first-class technical evaluation on a copper deposit that will put Argentina at the forefront of critical metals production supporting worldwide electrification and a greener future for generations to come."
Description of Results
Results are summarized on six schematic cross-sections that include simplified interpretations of the mineral zones including: Overburden, Leached, Enriched (also called Supergene) and Primary (also called Hypogene). The green line is the 30-year pit floor from the 2017 NI 43-101 Preliminary Economic Assessment (PEA) report. We see drill results that support and enhance our geological modelling.
Figure 1 is a plan view showing the location of these sections. The cross sections are located 50 m apart, with the lowest numbered section beginning at the south end of the deposit and numbers increasing to the north. For reference, Section 36 is located approximately in the center of the deposit.

Exploration Drilling
Hole AZ22174 (Figure1) is the 4th hole at Los Azules to be drilled to a depth in excess of 1,000 m. It represents the most recent validation that the deposit remains open at depth. It is located 900 m north of AZ22171 and was planned based on geophysical analyses and geological modelling. Results are expected to be available for release shortly. Logging of the core over its 1,100 m identified disseminated copper mineralization (chalcocite, chalcopyrite) hosted in pre-mineral diorite, copper in early veinlets and fracture-fills, magmatic hydrothermal breccia and potassic alteration as evidenced by potassium feldspar.
Infill Drilling Results Designed to Upgrade Copper Resources Classification to Measured & Indicated
Figure 2 - Section 36, includes an intercept of 190 m of 0.80% Cu (AZ22175), including a 94 m interval of 1.06% Cu in the Enriched mineral zone. The Enriched mineral zone is interpreted to occur as a sub-horizontal blanket of mineralization that varies in thickness between 150m and 250m across this section. This is typical of many world-class porphyry copper deposits. The hole was drilled to test for the presence of mineralization within a hydrothermal magmatic breccia host rock. Mineralization contained within this zone is on average associated with the highest copper grades at Los Azules.

Figure 3 - Section 41 shows an Enriched zone interval of 232m grading 0.59% Cu (AZ22172), including 32 m of 1.19% Cu. A portion of the shallower mineralization is hosted within an early mineral porphyry and the hydrothermal magmatic breccia associated with the porphyry. Like the breccia, the early mineral porphyry is an important host of higher-grade mineralization and is typically inclined sub-vertical. Closer to the hole's bottom, mineralization is hosted within rock known as diorite, which contains the majority of Primary zone sulphide-bearing mineralization at Los Azules. The drill hole ends with 197.0 m grading 0.31% Cu. Lithology and mineralization correlate well to hole AZ12106, suggesting great continuity.

Figure 4 - Section 42 profiles an Enriched zone interval of 232 m grading 0.51% Cu (AZ22177), including 56 m of 0.77% Cu. Again, the drill hole ended in the top of the Primary zone with 79 m of 0.39% Cu. The early mineralized porphyry, hydrothermal magmatic breccias and high copper grades noted in the hole are consistent with the nearby historic drill holes AZ12116 and AZ1048. The true thickness of the Enriched zone is interpreted to be up to 250 m on the section.

Figure 5 - Section 43 highlights 226 m grading 0.87% Cu (AZ22176) including 96 m of 1.13% Cu, and 262 m of 0.55% Cu (AZ22169) including 74 m grading 0.93% Cu. Both intervals correspond to the Enriched zone with a true thickness up to 250 m and signified in part by characteristic chalcocite copper mineralization and elevated soluble copper analyses. Mineralization is mainly related to the presence of early mineral porphyry and hydrothermal magmatic breccia. In hole AZ22176, the continued presence of copper mineralization at depth required drilling to continue below the 2017 PEA pit limit. The grades reported for the Primary zone correspond to a 121.9 m interval with a core length-weighted grade of 0.71% Cu. It is noteworthy that the hole ended in elevated copper grades, suggesting potential at depth and an attractive future drilling target.

Figure 6 - Section 44, profiles 238 m grading 0.55% Cu (AZ22170) and 237.2 m with 1.05% Cu (AZ22173), including a 108 m interval of 1.71% Cu. Both intercepts correspond to the Enriched zone, consistent with attractive grades reported in previous campaigns including 194 m of 0.56% Cu (AZ22163), 146 m of 1.10% Cu (AZ0620) and 80.4 m grading 0.21% Cu (AZ22167). The interpreted true thickness of the Enriched zone extends to 300 m at the center of the section, owing to the influence of structural controls such as faulting in the core of the deposit.

Figure 7 - Section 45 highlights 341 m of 0.53% Cu (AZ22171), including 88 m grading 1.06% Cu in the Enriched zone. The mineralization is primarily contained in hydrothermal magmatic breccia. The interpreted true thickness of up to 300 m in the Enriched zone extends from Section 44. The hole ended in primary mineralization of 35.2 m grading 0.27% Cu and remains open at depth.
