“We are pleased that significant developments on the advancement of the Los Azules Copper Project towards feasibility have brought Stellantis as a strategic partner in the future development of this giant copper, gold and silver project.
An additional investment of US $30 million in McEwen Copper was also invested by Rio Tinto’s Venture Nuton in 2023 after its initial investment of US $25 million in 2022,” stated Kirill Klip, TNR’s Chief Executive Officer. “TNR Gold’s vision is aligned with the leaders of innovation among automakers like Stellantis, with the aim of decarbonizing mobility, and our mining industry leaders like Rob McEwen’s vision ‘to build a mine for the future, based on regenerative principles that can achieve net zero carbon emissions by 2038’.
The green energy rEVolution relies on the supply of critical metals like copper; delivering “green copper” to Argentina and the world will contribute to the clean energy transition and electrification of transportation and energy industries.
Strong team performance is accelerating the McEwen Copper Los Azules program in 2023. The 2023 Los Azules Project PEA results highlighted the potential to create very robust leach project, while reducing environmental footprint and greater environmental and social stewardship sets the Project apart from other potential mine developments.
It’s very encouraging to see an updated independent mineral resource estimate that has increased significantly. Reported by McEwen Copper infill and other resource drilling completed since the PEA model data cut-off date results include significant copper values over wide intercepts and confirm very good alignment of new assay results to the resource model prediction for the same area.
Together with Nuton, McEwen Copper is exploring new technologies that save energy, water, time and capital, advancing Los Azules towards the goal of the leading environmental performance. The involvement of Rio Tinto with its innovative technology, may also accelerate realizing the enormous potential of the Los Azules Project.
Los Azules was ranked in the top 10 largest undeveloped copper deposits in the world by Mining Intelligence (2022). TNR Gold does not have to contribute any capital for the development of the Los Azules Project. The essence of our business model is to have industry leaders like McEwen Mining as operators on the projects that will potentially generate royalty cashflows to contribute significant value for our shareholders.”
NEWS RELEASE
TNR Gold NSR Royalty Update – Los Azules Copper, Gold & Silver Project – McEwen Copper Reports More Post-PEA Assay Results
"Vancouver, British Columbia – August 3, 2023: TNR Gold Corp. (TSX-V: TNR) (“TNR”, “TNR Gold” or the “Company”) is pleased to announce that McEwen Mining Inc. (“McEwen Mining”) has provided an update on the Los Azules copper, gold and silver project in San Juan, Argentina. TNR holds a 0.4% net smelter returns royalty (“NSR Royalty”) (of which 0.04% of the 0.4% NSR Royalty is held on behalf of a shareholder) on the Los Azules Copper Project. The Los Azules project is held by McEwen Copper Inc. (“McEwen Copper”), a subsidiary of McEwen Mining.
The news release issued on August 1, 2023, by McEwen Mining stated:
“TORONTO, Aug. 01, 2023 (GLOBE NEWSWIRE) — McEwen Copper Inc., 52% owned by McEwen Mining Inc. (NYSE: MUX) (TSX: MUX), today reports additional assay results of the recently completed drilling season at its Los Azules project, located in San Juan, Argentina.
“These assay results include significant copper values over wide intercepts and demonstrate very good agreement between these new assay results and those predicted by the resource block model used in the 2023 Preliminary Economic Assessment,” said Rob McEwen, Chairman & Chief Owner.
Los Azules is a large copper porphyry deposit with growth potential, it has many features comparable to world-class copper-gold deposits in South America and its depth and lateral extent have yet to be determined. Infill drilling serves several purposes, including providing better data density to increase confidence in the mineral resources, along with providing material and data for metallurgical, geotechnical, and hydrological studies.
Table 1 provides an overview of the new assay results. This infill drilling has been designed to upgrade the copper resource estimate classification from Inferred to Measured or Indicated.
Highlights
- Hole GTK2320 intercepted an Enriched zone of 386 meters (m) grading 66% Cu (est. true thickness) and includes a sub-interval of 196 m grading 0.99% Cu. (Figure 2)
- Hole GTK2319 intercepted an Enriched zone of 5 m grading 0.50% Cu (est. true thickness) and includes a sub-interval of 120 m grading 0.67% Cu. (Figure 3)
- Hole AZ23237 intercepted an Enriched zone of 308 m grading 69% Cu (est. true thickness) and includes a sub-interval of 142 m grading 0.82% Cu. (Figure 4)
- Hole AZ23233 returned an Enriched zone of 374 m grading 50% Cu including an Enriched zone intercept of 206 m grading 0.65% Cu. (Figure 5)
This recently completed phase of drilling occurred between October 2022 and June 2023 and used up to 15 rigs to complete 39,900 m of drilling in 138 holes, to evaluate geotechnical, hydrological, resource and exploration-related parameters and opportunities. The Los Azules drill hole database now totals 126,000 m.
To test the performance of the resource model copper grades versus actual drilling results, some 30 infill holes completed subsequent to the data cut-off on December 31, 2022, for the updated PEA model (released June 20, 2023) were utilized. The length-weighted average grade of the new drilling was 0.553% Cu compared to a resource model prediction of 0.515% Cu. This limited test of the resource model’s predictive capacity is encouraging, with actual grades 7.5% higher than the model prediction. Over time, we anticipate the local sensitivity of the model’s predictive capacity to improve, as drilling increases the geologic confidence required to delineate a Measured and Indicated mineral resource estimate.

Description of Results
The drilling results are summarized on four schematic cross sections that include interpretations of Overburden, Leached, Enriched (also called Supergene) and Primary (also called Hypogene) mineral zones. The green line on each section indicates the wall of the Base Case 27-year pit outline according to the updated PEA. Adjacent cross sections occur every 50 m, with the lowest section numbers located at the southern end of the field and increasing northwards.
Figure 1 – Cross Sections and Recent Drill Holes on the 2023 Base Case Mineable Resource Pit Plan
Figure 2 – Section 44 – Drilling, Mineral Zones & 2023 Base Case Mineable Resource Pit (Looking North)
Hole GTK2320, shown in the center of Figure 2, has been added to section 44 to infill a 200 m gap in drilling between holes AZ23218 and AZ22170. The hole returned an Enriched zone intercept higher than either of those holes, with 386 m of 0.66% Cu, including a sub-interval of 196 m of 0.99% Cu. Overall, the cross section is characterized by a 200-300 m flat-lying Enriched zone located immediately below a thin Leached zone horizon. Locally, the significant vertical extent exceeding 350 m reflects the favorable structural environment commonly found in the core of the deposit.
Figure 3 – Section 46 – Drilling, Mineral Zones & 2023 Base Case Mineable Resource Pit (Looking North)
Hole GTK2319, shown on section 46 in Figure 3, returned outstanding Enriched zone results of 383.5 m grading 0.50% Cu, including a sub-interval of 120 m grading 0.67% Cu. The hole highlights changes to grade and width toward the flank of the deposit. The mineralization and lithology are consistent with the previously released drilled hole AZ17126, which supports our view that continuity within the deposit is very good.
Figure 4 – Section 48 – Drilling, Mineral Zones & 2023 Base Case Mineable Resource Pit (Looking North)
Hole AZ23237 shown on section 48 in Figure 4, highlights a 308 m Enriched zone intercept grading 0.69% Cu, including a 142 m intercept of 0.82% Cu. The grade has increased toward the center of the section compared to hole AZ22161 immediately to the east. This is consistent with the overall trend of increasing grade from the flanks of the deposit toward its center.
