TNR Gold NSR Royalty Update - Los Azules Copper, Gold and Silver Project - McEwen Copper Announces Completion of the Feasibility Drilling Program

Vancouver, May 21, 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 May 16, 2024 stated:

"70,000 meters completed, highlights include:

349.0 m of 0.77% Cu, including 232.0 m of 0.86% Cu (AZ23292)

382.5 m of 0.54% Cu, including 74.0 m of 0.86% Cu (AZ23277)

McEwen Copper Inc., 47.7% owned by McEwen Mining Inc., is pleased to provide the assay results from the currently completed drill season at the Los Azules project in Argentina. The prime objectives of this season's infill drilling campaign were: 1. to confirm the size and grade of the deposit as compared to the 2023 PEA estimate and upgrade the resource categories for the upcoming feasibility study; 2. test for extensions of mineralization beyond the current pit shell; and 3. explore our large property package for other mineralized areas.

Based on the assay results received to date, our first objective appears to have been met. Initial interpretation suggests that our infill drilling will result in an increase in Measured and Indicated resources and an overall mineral inventory within 5% of the PEA estimate. Testing for extensions beyond the planned pit has successfully encountered mineralization both to the north and to the south. Primary mineralization was intercepted (202.0 m of 0.20% Cu) over 400 meters north of last year's deep exploration hole, confirming its extension at depth a significant distance to the north. Exploration south of the planned pit has intercepted the principal mineralized intrusive more than 700 meters south of previous drill intercepts and indicates that prospective intrusives continue well to the south of the pit.

Exploration over our property has produced an intriguing target, late in the season. Initial results of a concession-wide regional mapping and sampling campaign have identified strong evidence of a large porphyry system 3 kilometers east of the Los Azules deposit. Porphyry-style veining and quartz vein stockworks with copper oxide mineralization have been recognized within this new target, with assay results pending.

Additionally, this news release covers all results from the first half of the 2023-24 drill program (see Table 1). Final results will be published when all the geochemistry is completed.

The objective of the 2023-2024 drilling campaign is to collect all the necessary information to support the completion of the Los Azules Feasibility Study by early 2025. This information continues to arrive and will be processed in the following months. Resource drilling is focused on converting all the mineralization to be mined in the first 5 years to Measured and Indicated resource, to increase confidence during the payback period. Geotechnical, metallurgical, hydrogeological, exploration, and condemnation drilling are also being performed.

Highlights

• Hole AZ23292 returned an intercept of 349 m of 0.77% Cu (approx. true thickness). The Enriched zone portion of this hole extends over 346 meters and includes an intercept of 232 m of 0.86% Cu.
• Hole AZ23277 has an intercept of 382.5 m of 0.54% Cu (approx. true thickness). The Enriched zone portion of this hole extends over 306 meters with a grade of 0.61% Cu and includes an intercept of 74 m of 0.86% Cu.

Results

Results are summarized in two schematic cross sections (Figures 2 and 3), which include simplified interpretations of the Overburden, Leached, Enriched and Primary zones. The Enriched mineral zone refers to the enrichment of a copper deposit 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 aid in this process. Below the Enriched zone, the Primary (or Hypogene) zone is formed by ascending copper-rich fluids having a much deeper magmatic origin. The green line on the sections 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 two 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.

Growing the Deposit

Exploration hole AZ23241 (Figure 4) intersected a long interval of low-grade mineralization in the Primary Zone (202.0 m of 0.20% Cu) and began to enter higher-grade mineralization at the end of the hole (12.0 m of 0.44% Cu). This hole is located completely outside of the 2023 PEA base case mineable pit shell. This hole is over 400 meters to the north of exploration hole AZ22174, also located outside of the 2023 PEA base case mineable pit shell, which encountered 1,052.0 m of 0.29% Cuincluding 480 m of 0.42% Cu (Figure 4). These intercepts suggest that primary mineralization continues at depth a significant distance to the north. Exploration drilling south of the deposit has extended the presence of the early mineral porphyry more than 700 meters south of previous drilling and well outside of the southern pit boundary. This porphyry is host for the majority of the mineralization at Los Azules and encountering it a significant distance farther south indicates that the deposit may also continue in this direction. Assays for these holes are pending.

A comprehensive structural model for the deposit has been completed that will provide a better understanding of structural controls on the deposit and aid in future exploration work. Field verification of a previous property-wide structural study using satellite information was carried out in January and has refined the identification of nearby exploration targets.

Indications of Another Porphyry Copper System Nearby

To date, geological mapping and geochemical sampling has been focused primarily near the Los Azules deposit and only covers roughly 40% of our large concession. To address this limitation, a mapping and sampling campaign was begun in December, to obtain 100% coverage of our concession.

Early results of this work have identified a large new porphyry system 3 kilometers east of Los Azules. Preliminary work has identified porphyry-style veining and alteration, indicating the presence of a porphyry copper system. Areas with strong quartz vein stockworking and the recognition of copper oxides at surface add to the prospectiveness of this newly identified area (Figure 5).
