TNR Gold NSR Royalty Update - Los Azules Copper, Gold and Silver Project - McEwen Copper Updates on Assay Results at Los Azules

Vancouver, March 5, 2024 - TNR Gold Corp. (TSXV: 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 by McEwen Mining on February 26, 2024 stated:

"McEwen Copper Inc., 47.7% owned by McEwen Mining Inc. is pleased to announce assay results from the final unreleased drill holes of the last season (2022-2023). The results from this period not only validate previous drilling results but also confirm the continuity of mineralization and extend the mineralization.

Remaining assays from the 2022-2023 season, highlights include:

• 446 m of 0.63% Cu, including 76 m of 0.92% Cu (AZ23228MET)

Selected Highlights:

• Hole AZ23205MET returned 257 m of 0.76% Cu within the Enriched zone.

• Hole AZ23228MET returned 446 m of 0.63% Cu in the Enriched zone, including 76 m of 0.92% Cu.

• Hole AZ23230MET returned 250 m of 0.68% Cu in the Enriched zone, including 192 m of 0.83% Cu.

The objective of the 2022-2023 drilling campaign was to collect information needed as the project advances towards the completion of a Feasibility Study in Q1 2025. Work continues during this field season (2023-2024) and includes resource drilling that will convert the initial 5-year pit resources to Measured and Indicated categories and will further upgrade resources from Inferred to Indicated. In addition to resource drilling, geotechnical, metallurgical, hydrogeological, exploration, and condemnation drilling are also being performed.

With the closing in October 2023 of a US$10.0 million investment by Nuton, a Rio Tinto venture, and the ARS $42 billion investment by Stellantis, the Los Azules Project is fully funded for the 2023-2024 drilling campaign. McEwen Copper is currently seeking funding to support feasibility-level engineering and pre-construction work. Another record-setting drill season is underway at Los Azules with over 62,000 meters of drilling, of which 43,000 meters have been completed to date.

"Argentina's new president is taking important initiatives to unlock the country's potential to become a significant supplier of critical minerals to the world, to combat climate change and at the same time strengthening the economy," said Rob McEwen, Chairman and Chief Owner.

"McEwen Copper's Los Azules project is progressing at light speed towards completing a feasibility study by Q1 2025 and it has already delivered significant economic benefits to the neighbouring communities. It is a very large copper resource, where recent exploration drilling suggests it definitely has room to grow," said Michael Meding, Vice President and General Manager of McEwen Copper.

Table 1 - Remaining 2022-2023 Los Azules metallurgical drilling results. All intercepts are approximate true thickness.

Results are summarized in three schematic cross sections (Figures 2, 3, and 4), which include simplified interpretations of the Overburden, Leached, Enriched and Primary zones. The Enriched mineral zone refers to a copper deposit enriched by precipitation-derived water circulation that carries copper minerals downward through the rocks to accumulate in a thick, often horizontal "blanket". Immediately above the Enriched zone is the Leached zone, from which copper was removed and transported. Weathering and oxidation often contribute to this process. Below the Enriched zone, the Primary (or Hypogene) zone is formed by ascending copper-rich thermal fluids, originating from a much deeper magmatic source. The green line indicates the pit floor of the 30-year pit shell from the 2023 NI 43-101 Preliminary Economic Assessment (PEA).

Figure 1 presents a plan view of the location of three sections and the holes reported. Adjacent cross sections are located 50 m apart from each other, starting with the lowest numbered section at the south end of the deposit and progressing to the north.

Technical information

The technical content of this press release has been reviewed and approved by Darren King, Director of Exploration of McEwen Copper, who serves as the qualified person (QP) under the definitions of National Instrument 43-101.

All samples were collected in accordance with generally accepted industry standards. Drill core samples, usually taken at 2 m intervals, were split and submitted to the Alex Stewart International laboratory located in the Province of Mendoza, Argentina, for the following assays: gold determination using fire fusion assay and an atomic absorption spectroscopy finish (Au4-30); a 39 multi-element suite using ICP-OES analysis (ICP-AR 39); copper content determination using a sequential copper analysis (Cu-Sequential LMC-140). An additional 19-element analysis (ICP-ORE) was performed for samples with high sulphide content and that exceeded the limits of the ICP-OES analysis.

The company conducts a Quality Assurance/Quality Control program in accordance with NI 43-101 and industry best practices, using a combination of standards and blanks on approximately one out of every 25 samples. Results are monitored as final certificates are received, and any re-assay requests are sent back immediately. Pulp and preparation sample analyses are also performed as part of the QAQC process. Approximately 5% of the sample pulps are sent to a secondary laboratory for control purposes. In addition, the laboratory performs its own internal QAQC checks, with results made available on certificates for Company review.
