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

Vancouver, British Columbia--(Newsfile Corp. - April 11, 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. The Los Azules is held by McEwen Copper Inc. ("McEwen Copper"), a subsidiary of McEwen Mining.

The news release issued by McEwen Mining stated:

"TORONTO, April 05, 2023 -- McEwen Copper Inc., 52%-owned by McEwen Mining Inc. (NYSE: MUX) (TSX: MUX), is pleased to report the latest assay results from Los Azules, where an ongoing drilling program continues to deliver consistent infill results. 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 (or Supergene) mineralization.

Significant Infill Intercepts
0.50% Cu over 502 m, including 0.87% Cu over 172 m (AZ22181)
1.00% Cu over 282 m, including 1.40% Cu over 172 m (AZ22186)
0.66% Cu over 500 m, including 0.92% Cu over 276 m (AZ22184A)

Highlights

• Hole AZ22183 returned an Enriched zone intercept of 0.87% Cu over 152 m (est. true thickness) which expands mineralization from adjacent high-grade results drilled in prior programs (Figure 1 and 2).

• In hole AZ22184A, an Enriched zone interval grading 0.92% Cu over 276 m (est. true thickness) occurs in a hydrothermal magmatic breccia within the core of the deposit (Figure 3). This breccia unit acts as a conduit for mineralizing fluids, sometimes forming higher grades within the broader porphyry mineralization at Los Azules.

• Hole AZ22181 returned an Enriched zone intercept of 0.87% Cu over 172 m (est. true thickness) and fills a gap between high-grade holes drilled earlier in 2022 (Figure 4).

• Hole AZ22186 includes an interval grading 1.00% Cu over 282 m (true thickness of 247 m) in the Enriched zone nearby a historic high-grade- intercept (Figure 5).

'We have four different drilling contractors with 13 drills turning,' commented Michael Meding, Vice President and General Manager of McEwen Copper. 'This initiative also involves training and optimizing the entire value chain, with the significant engagement of local suppliers and services.'

After resuming the exploration program in October 2022, drilling has now reached the 25,000 meters initially planned and will continue until the end of the field season. Key objectives of the program include:

• Increasing drilling density to upgrade the classification of shallower copper resources to measured and indicated categories.

• Providing metallurgical, hydrological and geotechnical data for the feasibility study mine design to be completed in late 2024.

• Testing for extensions of Los Azules mineralization to the north, south and at depth.

Table 1 presents the summary of copper (Cu), gold (Au) and silver (Ag) assay results from nineteen recently completed exploration or geotechnical holes totaling some 8,000 meters of core.

Table 1 - Los Azules drilling results, February - March 2023

Results are summarized on four schematic cross-sections that include simplified interpretations of overburden thickness and the Leached, Enriched and Primary mineral zones. The Enriched (or Supergene) 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 outlines the 30-year pit floor from the 2017 NI 43-101 Preliminary Economic Assessment (PEA) report. Figure 1 is a plan view showing the location of these cross sections.

The cross sections are located 50 m apart, with the lowest numbered section beginning at the south end of the deposit and increasing to the north.

In Figure 2, Section 38 shows an intercept of 0.87% Cu over 152 m (AZ22183) in the Enriched zone. Immediately to the east of this hole, the Enriched zone is modelled with a true thickness exceeding 300 m based on historic drilling results including 0.72% Cu over 333.1 m (AZ1168) and 0.74% Cu over 313.1 m (AZ1063). In this interval, the dominant copper mineral is chalcocite, which is highly soluble and an attractive attribute from a metallurgical point of view is that it allows for simplified recovery of much of the copper.

In Figure 3, Section 39 shows an intercept of 0.66% Cu over 500m (AZ22184A), including 0.92% Cu over 276 m in the Enriched zone and 0.34% Cu over 224 m in the deeper Primary zone. It is notable that the Enriched zone includes a high-grade sub-interval of 1.40% Cu over 76 m, associated with hydrothermal magmatic breccia. The breccia unit is the highest-grade domain modelled at Los Azules. The true thickness of the Enriched zone exceeds 300 m in the center of the section due to the influence of structural controls, such as faults, which affect the core of the deposit.

In Figure 4, Section 40, hole AZ22181 shows a grade of 0.50% Cu over501.9 m, including 0.87% Cu over 172 m in the Enriched zone and 0.31% Cu over 329.9 m in the Primary zone. Further to the west, hole AZ22188 shows an Enriched zone intercept grading 0.78% Cu over 128 m and includes 1.04% Cu over 42 m. Grades are consistent with those reported in the previous campaign for hole AZ22146 (0.83% Cu over 330.5 m). The Enriched zone is estimated up to 300 m in vertical thickness immediately east of hole AZ22181.

In Figure 5 below, Section 46 shows hole AZ22186 with an Enriched zone interval grading 1.00% Cu over 282 m including 1.40% Cu over 172 m, where the hydrothermal magmatic breccia is well mineralized. The intercept compares well with nearby historic hole AZ0619 which graded 1.67% Cu over 199.8 m.
