"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.

"We are pleased that significant developments on the advancement of the Los Azules Copper Project towards feasibility have led to the increased Stellantis holdings in McEwen Copper as a strategic partner of this large copper, gold and silver project. In February 2023, Stellantis invested ARS $30 billion, and with additional investment of ARS $42 billion made after the new preliminary economic assessment (PEA) publication, has a total investment of ARS $72 billion. An aggregate of US $65 million in McEwen Copper was also invested by Rio Tinto's Venture Nuton in 2022 and 2023," stated Kirill Klip, TNR's Chief Executive Officer. "TNR Gold's vision is aligned with the leaders of innovation among automakers like Stellantis, whose aim is decarbonizing mobility, and mining industry leaders such as Rob McEwen, whose vision is '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.

"The new president of Argentina introduced important government policies aimed at supporting business and unlocking the country's economic potential. Mining is being recognized as an integral part of this economic development plan providing jobs and enriching local communities.

"Strong team performance of McEwen Copper is accelerating the advance of Los Azules Project towards completing a feasibility study. The Los Azules Project PEA results highlighted the potential to create a 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 also very encouraging to see an updated independent mineral resource estimate that has increased significantly. These assay results not only validate previous drilling results but also confirm the continuity of mineralization and extend the mineralization.

"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."

ABOUT TNR GOLD CORP.

TNR Gold Corp. is working to become the green energy metals royalty and gold company.

Our business model provides a unique entry point in the creation of supply chains for critical materials like energy metals that are powering the energy rEVolution, and the gold industry that is providing a hedge for this stage of the economic cycle.

Our portfolio provides a unique combination of assets with exposure to multiple aspects of the mining cycle: the power of blue-sky discovery and important partnerships with industry leaders as operators on the projects that have the potential to generate royalty cashflows that will contribute significant value for our shareholders.

Over the past twenty-eight years, TNR, through its lead generator business model, has been successful in generating high-quality global exploration projects. With the Company's expertise, resources and industry network, the potential of the Mariana Lithium Project and Los Azules Copper Project in Argentina among many others have been recognized.

TNR holds a 1.5% NSR Royalty on the Mariana Lithium Project in Argentina, of which 0.15% NSR royalty is held on behalf of a shareholder. Ganfeng Lithium's subsidiary, Litio Minera Argentina ("LMA"), has the right to repurchase 1.0% of the NSR royalty on the Mariana Project, of which 0.9% is the Company's NSR Royalty interest. The Company would receive CAN$900,000 and its shareholder would receive CAN$100,000 on the repurchase by LMA, resulting in TNR holding a 0.45% NSR royalty and its shareholder holding a 0.05% NSR royalty.

The Mariana Lithium Project is 100% owned by Ganfeng Lithium. The Mariana Lithium Project has been approved by the Argentina provincial government of Salta for an environmental impact report, and the construction of a 20,000 tons-per-annum lithium chloride plant has commenced.
