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

Vancouver, British Columbia--(Newsfile Corp. - May 9, 2023) - TNR Gold Corp. (TSXV: TNR) ("TNR", "TNR Gold" or the "Company") is pleased to announce an update from McEwen Mining Inc. ("McEwen Mining") 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. Los Azules is held by McEwen Copper Inc. ("McEwen Copper"), a subsidiary of McEwen Mining.

The news release issued by McEwen Mining stated:

"TORONTO, May 05, 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)."

Located in San Juan, Argentina, the Los Azules Project has many features comparable to world-class copper-gold deposits in South America, including a thick blanket of higher-grade Enriched mineralization.

Significant Infill Intercepts

231 m of 0.97% Cu, including 188 m of 1.09% Cu (AZ22182A)

550 m of 0.50% Cu, including 216 m of 0.72% Cu (AZ23196)

Highlights

• Hole AZ22182A intercepted an Enriched zone of 231 m of 0.97% Cu (est. true thickness) and a Primary zone with mineralization that remains "open" at depth.

• Hole AZ23196, returned an overall intercept of 550 m of 0.50% Cu (est. true thickness) and included 216 m of 0.72% Cu within the Enriched zone portion.

• Drilling completed during the current season to April 30^th stands at 32,758 m in 125 holes, having exceeded the 25,000 meters initially planned. Drilling will continue until the end of the field season in May and will resume in October, at the end of winter in Argentina.

Table 1 summarizes recent copper (Cu), gold (Au) and silver (Ag) assay results.

Figure 1 presents a plan view of the location of four 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.

Table 1 - Recent Los Azules Drilling Results

Results are summarized in four schematic cross sections (Figures 2 to 5), 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 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).

Figure 2 highlights a 231 m interval in the Enriched zone grading 0.97% Cu (AZ22182A), including 188 m grading 1.09% Cu within the center of the section. Drilling on this section is more limited laterally and has not tested the Primary zone beyond a 16.6 m interval, which graded 0.55% Cu. The interpretation of the mineral zones is supported by the definition drilling completed 50 m away on Section 36 (not shown) during the 2022 portion of the program.

Figure 3 presents an overall 550 m intercept of 0.50% Cu (AZ23196). Its Enriched zone measures 486 m of 0.52% Cu, including a 216 m sub-interval of 0.72% Cu. These values correlate well with nearby holes, such as AZ22176 with 226 m grading 0.87% Cu (including 96 m grading 1.13% Cu) and hole AZ22169, with 262 m grading 0.55% Cu (including 74 m grading 0.93% Cu). Both intervals correspond to the Enriched zone, which is interpreted to have a true thickness of 200 m to 250 m. Copper mineralization is tested with limited drilling at depth on this section.

Figure 4 highlights 186 m grading 0.52% Cu, including 78 m of 0.64% Cu (AZ23201) in the Enriched zone. The hole continues in the Primary zone with a 195 m section grading 0.59 % Cu and remains open at depth. The nearby previously released hole AZ22171 showcases 341 m grading 0.53% Cu, including 88 m grading 1.06% Cu in the Enriched zone and the hole ending in 35.2 m grading 0.27% Cu in the Primary zone.
