TNR Gold Corporate Update and Strategic Review of the Developing M&A Opportunities

Vancouver, British Columbia--(Newsfile Corp. - November 28, 2025) - TNR Gold Corp. ("TNR", "TNR Gold" or the "Company") is pleased to provide a corporate update and announce that the Company is continuing its strategic review of developing M&A opportunities.

"TNR Gold Corp is your gateway to the green energy rEVolution and gold stability," stated Kirill Klip, Executive Chairman of TNR Gold Corp. "We're building a leading green energy metals royalty and gold company, offering a unique entry into the supply chains powering the energy transition. With a 1.5% net smelter returns ("NSR") royalty on the Mariana Lithium Project in Argentina (0.15% NSR royalty is held on behalf of a shareholder), operated by Ganfeng Lithium, and a 0.4% NSR royalty on the Los Azules Copper Project with McEwen Inc. (0.04% of NSR royalty is held on behalf of a shareholder) — backed by majors like Rio Tinto and Stellantis — TNR is potentially positioned for significant cash flows without the capital burden. Add to that our 90% stake in the Shotgun Gold Project in Alaska, near the Donlin Gold deposit, with 705,960 ounces of inferred gold resources, and the Company is also well diversified. TNR delivers exposure to lithium, copper, silver and gold, blending blue-sky discovery with partnerships that drive value, in turn offering potential growth with a hedge in today's economic cycle."

Strategic Priorities

Our priorities remain focused on maximizing value for all our shareholders by preventing unnecessary dilution, reducing general and administrative expenses and delivering above the market returns for our investors. Our strategic action plan includes, but is not limited to, the following initiatives:

Marketing Success and Industry Recognition

• Recent increased M&A interest from numerous parties suggests that TNR's management ("Management") has succeeded with its marketing activity by presenting the Company's GEM Royalty Story to the mining and investment industries.

• In February 2023, Lithium Royalty Corp. valued only a portion of the Company at US$9 million, based on its purchase of the 0.5% NSR royalty involving the Mariana Lithium project for US $9 million.

• Our team has successfully repaid TNR Gold's investment loan in full, returning our shareholders all our assets free from encumbrance. The value generated from delivering that strategic transaction has justified Management's stance on rejecting other opportunistic low-ball offers.

Delivering Value in Uncertain Times and Planning Ahead

• Management has succeeded in delivering solid values in uncertain times. The Company's share price has performed above the market average, not only during very challenging market times of the COVID-19 pandemic, but also during the market rout following the U.S. tariff announcements. This has justified the strategy of TNR's board of directors (the "Board") of presenting the Company as a structural hedge in an investment portfolio.

• Management has been investing in TNR Gold for over than two decades and continues to support our Company by participating in private placements, even during the darkest hours of the COVID-19 pandemic. Management resumed its buying of shares of the Company and increased its stake in TNR Gold.

• Management proposes to hold its 2026 Annual General Meeting of Shareholders on June 16, 2026. Further details will be provided closer to the meeting and included in its management information circular for such meeting. The Company will place before the meeting its audited financial statements for its financial year ended December 31, 2025. Items of annual business include election of directors and appointment of auditor. The Company will also present its stock option plan for annual approval in accordance with the policies of the TSX Venture Exchange.

Strategic Growth and Stability

• TNR Gold's assets are now well recognized within the mining and investment industries. The Company has received indications of further M&A interest from numerous parties and even successfully defended our Company from the opportunistic low-ball hostile takeover attempts.

• On October 12, 2023, TNR announced that the Board had formed a special committee comprised of independent directors (the "Special Committee") to consider and evaluate strategies to maximize shareholder value, including pursuing one or more strategic transactions. Management continues to work diligently with the Special Committee in order to capitalize on potential transactions, including potential further royalty acquisitions. We believe the Company is a leader among its industry peers in maintaining integrity and consideration towards our retail shareholders, while prioritizing the discipline in order to unlock the full potential valuations of our assets. TNR's Shareholder Rights Plan allows us to pursue the most appealing transactions for the benefit of all our shareholders while avoiding predatory tactics like crawling takeover attempts and low-ball opportunistic offers.

• Management is currently working on new avenues to open the new chapter of growth for the Company's GEM royalty, including trying to facilitate potential strategic alliances with major mining companies and investment institutions. If successful, such alliances would allow us to unlock higher valuations of our royalty holdings and generate new capital without diluting the Company's current shareholders.

• Management believes that in order to maximize shareholder value and reach the potential valuations reflecting the intrinsic value of the Company's assets, TNR must preserve capital, reduce its number of outstanding shares, and seek outside investment for the development of the Shotgun Gold Project.

• Management believes that potential cash flow expected to be generated from TNR's royalties and capital management strategy would be well used to implement a normal course issuer bid (subject to regulatory approval) in order to reduce the Company's float of shares and deliver returns to its shareholders.

• Management is considering the best value-creation strategies for the Shotgun Gold Project and has put in place the corporate structure of AmeriGold — the stand-alone company that could potentially inherit the Shotgun Gold Project joint venture operations after the contemplated potential spinout from TNR Gold.

• By maintaining this strategic approach, we aim to continue generating substantial value for our shareholders while ensuring long-term stability and growth.

"We are building the Green Energy Metals Royalty and Gold Company," continued Kirill Klip. "Our business model provides a unique entry point into the creation of supply chains for critical materials like energy metals which are powering the Energy rEVolution, and the gold industry which is providing the ultimate hedge during this part of the economic cycle. Our shareholders are participating in the building of The Green Energy Metals Royalty and Gold Company. In our portfolio, we have a unique combination of assets providing exposure to different parts of the mining cycle, starting with the power of blue-sky discovery and including partnerships with industry leaders like McEwen Inc. Ganfeng Lithium, Lundin Mining and BHP as operators on the projects that could potentially generate royalty cashflows to contribute significant value for our shareholders."

TNR Gold's motto remains: "Solid Values in Uncertain Times".

Shotgun Gold Project — Alaska

The Shotgun Gold Project is an advanced-stage exploration prospect in southwestern Alaska. The Company's exploration field program in 2022-2023 at the Shotgun and Winchester prospects, located in the Taylor Mountain Quadrangle, Alaska, investigated the geochemical anomalies generated by the 1998 Novagold Resources soil surveys and the geophysical targets indicated by anomalies from the SJ Geophysics 2011 and 2012 EM surveys.

"The Company's strategy with the Shotgun Gold Project is to attract a partnership with a major gold mining company. TNR Gold has successfully consolidated and updated its mining claims in Alaska and is actively introducing the project to interested parties," commented Kirill Klip. "There is a clear path on how to move this prospective project forward using the geological and geophysical research currently available to target drilling to expand the resource. The next step is to acquire a partner that shares our vision and recognizes the growth potential and value to be added to the Shotgun Gold Project over time. The latest exploration program allows us to provide additional information on TNR's Shotgun Gold Project for our potential strategic partners."

The strategy presented to potential strategic partners involves the creation of a joint venture with a major gold mining company, where TNR's partner would invest substantial capital in the development of the Shotgun Gold Project while earning a stake in the project.

TNR Gold shareholders would benefit from the strategic partner's capital being invested "in the ground", and industry expertise, including operations in Alaska.

Management is investigating the best value-creation strategies for the Shotgun Gold Project and has put in place the corporate structure of AmeriGold — the stand-alone company that could potentially inherit the Shotgun Gold Project joint venture operations after a potential spinout from TNR Gold.

TNR holds a 90% interest in the Shotgun Gold Project that is located 190 kilometres south of the Donlin Gold Project deposits within the Kuskokwim Gold Belt in southwestern Alaska. This area is emerging as a multi-million-ounce gold district. The Shotgun property includes a number of prospects, including Shotgun Ridge and nearby Winchester. The Donlin Gold Project is an intrusion-associated system and represents one of the largest undeveloped gold deposits in the world. The Company believes that there are several key similarities between prospects on the Shotgun property and those of the Donlin Gold Project deposits, as well as other important intrusion-associated deposits worldwide.

The Company is targeting a large tonnage porphyry system at Shotgun Ridge. Structural repeats, as interpreted from airborne magnetic data and ground geophysical surveys, provide TNR with encouraging targets for future drill testing.

Detailed information about the inferred mineral resource estimate is included in the technical report titled, "Technical Report on the Shotgun Gold Project, Southwest Alaska", dated May 27, 2013 that can be found on the TNR Gold website at www.tnrgoldcorp.com or on SEDAR+ at www.sedarplus.ca.

Mariana Lithium NSR Royalty Holding

On February 20, 2025, TNR Gold announced that Ganfeng Lithium Group Co., Ltd. ("Ganfeng") provided an update on the Mariana Lithium Project. 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 of TNR.

On February 14, 2025, Ganfeng announced commencement of formal production of the Mariana Lithium salt-lake project in Argentina. Ganfeng stated in its announcement:

"A production ceremony for the first phase of the Mariana lithium salt-lake project in Argentina owned by Litio Minera Argentina S.A. (hereinafter referred to as "LMA"), a wholly-owned subsidiary of Ganfeng Lithium Group Co., Ltd. was held at the project site on 12 February 2025, which means the formal production of the first phase of the Mariana lithium salt-lake project.

Mariana lithium salt-lake project is located in Salta Province, Argentina, with total lithium resources of approximately 8,121,000 tons of LCE currently explored. After the formal production of the first phase of Mariana lithium salt-lake project with an annual production capacity of 20,000 tons of lithium chloride production line, the Company will actively accelerate the ramp-up of the production capacity of the project. With the gradual release of production capacity, the supply and cost structure of the lithium resources of the Company will be further optimized, the Company's profitability will be enhanced, and the Company's core competitiveness in the global market will be continuously improved.

The Company will perform the corresponding procedures and obligation of information disclosure according to the subsequent progress of the relevant matters. Investors are advised to invest rationally and pay attention to the investment risks."

On April 30, 2025, Ganfeng in Its 2024 Annual Report stated:

"Mariana is a lithium-potassium salt lake located in Salta Province, Argentina. According to a technical report issued by Golder Associates Consulting Ltd., the total lithium resources at the Mariana lithium salt lake project amounted to approximately 8,120,000 tons of LCE. The construction of the project has been completed. In February 2025, the production line for phase I of the Mariana lithium salt-lake project with a planned annual production capacity of 20,000 tons of lithium chloride was officially put into operation. The Company will accelerate the progress of the production capacity ramp-up of the project, and it is expected that the Mariana project will gradually supply lithium chloride products in a stable manner from the second half of 2025 onwards."

On September 30, 2025, Ganfeng in Its 2025 Interim Report stated:

"Securing high-quality and stable lithium resources is fundamental​ to the long-term sustainable growth of our business. The Company​ adheres to the aim of globalizing the layout of its resources, and​ will continuously expand its current lithium resources portfolio​ through further exploration, and actively improve the self-​sufficiency rate of resources of the Company. In terms of brine, ​ the Company will proactively advance the development and​ construction of the Mariana lithium salt-lake project..."

"We are very pleased that Ganfeng officially inaugurated the Mariana Lithium's start of production at a 20,000 tons-per-annum lithium chloride plant on February 12, 2025," commented Kirill Klip. "We are looking forward to our first NSR royalty cash flow payment from the Mariana Lithium Project.

TNR does not have to contribute any capital for the development of the Mariana Lithium Project, the Los Azules Copper Project or the Josemaria Project. The essence of our business model is to have industry leaders like Ganfeng as operators on the projects that will potentially generate royalty cashflows to contribute significant value for our shareholders."

Los Azules Copper, Gold and Silver NSR Royalty Holding

On October 10, 2025, TNR Gold announced that McEwen Inc. provided an update on the Los Azules Copper Project in San Juan, Argentina. TNR holds a 0.4% NSR royalty (of which 0.04% of the 0.4% royalty is held on behalf of a shareholder of TNR) on the Los Azules Copper Project. The Los Azules Copper Project is held by McEwen Copper Inc., a subsidiary of McEwen Inc.

An excerpt from a news release issued by McEwen Inc. on October 7, 2025, is below. For additional details, please refer to the McEwen Inc. website.

Kirill Klip stated, "We are pleased that McEwen Copper has reached this major milestone releasing feasibility study after it secured an environmental permit for the construction and operation of the Los Azules copper project. The feasibility study confirms that Los Azules copper is economically robust project with leading ESG performance. The collaboration between McEwen Copper and IFC, and admission to the Argentina Regime of Incentives for Investment (RIGI) could move the Los Azules copper project development closer to a construction decision.

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

Our Company has repaid our investment loan in full, and we believe that the recent market prices of our shares do not properly reflect the underlying value of TNR's assets. Our transformation from a project generation junior mining company into a cashflow-generating royalty company may bring the necessary catalyst for improved market valuation of our assets.

Significant developments on the advancement of the Los Azules project towards the feasibility stage have led to increased Rio Tinto and Stellantis holdings in McEwen Copper, strategic partners of this large copper, gold and silver project. In 2023, Stellantis invested an aggregate ARS $72 billion. An additional US $100 million in total was invested by Rio Tinto's Venture Nuton® in McEwen Copper. TNR Gold's vision is aligned with the leaders of innovation among automakers like Stellantis, whose aim is to decarbonize 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'.

Together with Nuton®, McEwen Copper is exploring new technologies that save energy, water, time and capital, advancing Los Azules towards the goal of leading environmental performance. The involvement of Rio Tinto, with its innovative technology, may also accelerate realizing the potential of the Los Azules project.

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 feasibility study confirms Los Azules project as a long-life, low-cost producer of high-purity copper cathodes with strong economic returns and sustainability. It highlights the potential to create a robust leach project while reducing the environmental footprint, and greater environmental and social stewardship sets the project apart from other potential mine developments.

Los Azules was ranked in the top ten 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 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 will potentially generate royalty cashflows to contribute significant value for our shareholders.

Over the past twenty-nine 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% of such NSR royalty is held on behalf of a shareholder of the Company. 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. Ganfeng officially inaugurated Mariana Lithium's start of production at a 20,000 tons-per-annum lithium chloride plant on February 12, 2025.

TNR Gold also holds a 0.4% NSR royalty on the Los Azules Copper Project, of which 0.04% of the 0.4% NSR royalty is held on behalf of a shareholder of the Company. The Los Azules Copper Project is being developed by McEwen Inc.

TNR also holds a 7% NPR on the Batidero I and II properties of the Josemaria Project that is being developed by the joint-venture between Lundin Mining and BHP.

TNR provides significant exposure to gold through its 90% holding in the Shotgun Gold porphyry project in Alaska. The project is located in Southwestern Alaska near the Donlin Gold project, which is being developed by Barrick Gold and Novagold Resources. The Company's strategy with the Shotgun Gold Project is to attract a joint venture partnership with a major gold mining company. The Company is actively introducing the project to interested parties.

At its core, TNR provides a wide scope of exposure to gold, copper, silver and lithium through its holdings in Alaska (the Shotgun Gold porphyry project) and royalty holdings in Argentina (the Mariana Lithium project, the Los Azules Copper Project and the Batidero I & II properties of the Josemaria Project), and is committed to the continued generation of in-demand projects, while diversifying its markets and building shareholder value.

Cautionary Statement Regarding Forward-Looking Information

Except for statements of historical fact, this news release contains certain "forward-looking information" within the meaning of applicable securities law. Forward-looking information is frequently characterized by words such as "plan", "expect", "project", "intend", "believe", "anticipate", "estimate", "will", "could" and other similar words, or statements that certain events or conditions "may" or "could" occur, although not all forward-looking statements contain these identifying words. Specifically, forward-looking statements in this news release include, but are not limited to, statements made in relation to: TNR's corporate objectives and future potential transactions being considered by the Special Committee and the Board, and the benefit that TNR's shareholders may derive from same; TNR's future receipt of cash flows from its royalty holdings and the subsequent contribution of significant value to its shareholders; the possible growth of TNR's value; timing for its 2026 AGM; future revenue and increased valuations of TNR's royalty holdings caused by potential strategic alliances with major mining companies and investment institutions; the use of potential future cash flows to fund a normal course issuer bid; the potential spin-out of the Shotgun Gold Project; future investment of substantial capital in the development of the Shotgun Gold Project by a potential partner of TNR; the future potential of the Kuskokwim Gold Belt in southwestern Alaska; the possible benefits that may accrue to the Los Azules copper project; the potential acceleration of the Los Azules project's potential due to Rio Tinto's involvement in the project; and the potential benefits caused by delivering 'green copper' to Argentina and the world. Such forward-looking information is based on a number of assumptions and subject to a variety of risks and uncertainties, including but not limited to those discussed in the sections entitled "Risks" and "Forward-Looking Statements" in the Company's interim and annual Management's Discussion and Analysis which are available under the Company's SEDAR+ profile on www.sedarplus.ca. While management believes that the assumptions made and reflected in this news release are reasonable, should one or more of the risks, uncertainties or other factors materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those described in forward-looking information. In particular, there can be no assurance that: TNR will enter into one or more strategic transactions, partnership or a spin-out, or be able to complete any further royalty acquisitions or sales of royalty interests, or portions thereof; debt or equity financings will be available to TNR; or that TNR will be able to achieve any of its corporate objectives. TNR relies on the confirmation of its ownership for mining claims from the appropriate government agencies when paying rental payments for such mining claims requested by these agencies. There could be a risk in the future of the changing internal policies of such government agencies or risk related to the third parties, in future, challenging the ownership of such mining claims. Given these uncertainties, readers are cautioned that forward-looking statements included herein are not guarantees of future performance, and such forward-looking statements should not be unduly relied on.

In formulating the forward-looking statements contained herein, management has assumed that business and economic conditions affecting TNR, and its royalty partners, McEwen Inc., Ganfeng Lithium and Lundin Mining will continue substantially in the ordinary course, including without limitation with respect to general industry conditions, general levels of economic activity and regulations. These assumptions, although considered reasonable by management at the time of preparation, may prove to be incorrect.

Forward-looking information herein and all subsequent written and oral forward-looking information are based on estimates and opinions of management on the dates they are made and are expressly qualified in their entirety by this cautionary statement. Except as required by law, the Company assumes no obligation to update forward-looking information should circumstances or management's estimates or opinions change.
