TNR Gold Corp. (TSX-V: TNR) is pleased to announce that it has entered into a definitive arrangement agreement dated November 11, 2026 with Altius Minerals Corporation (TSX: ALS) (OTCQX: ATUSF) pursuant to which Altius will acquire all of the issued and outstanding common shares of TNR Gold that it does not already own, and TNR Gold will spin out its interest in the Shotgun Gold Project in Alaska to a new company. Under the terms of the Arrangement Agreement, for each TNR Share held, TNR shareholders (other than Altius and dissenting shareholders) will receive 0.0072 of a common share of Altius and 0.25 of a common share of SpinCo. The Transaction will be implemented by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia).

The Transaction follows the Company’s announcement on October 7, 2026, that it had received an unsolicited non-binding proposal from Altius regarding the potential acquisition of all TNR Shares not already owned by Altius, and that, following a review of the proposal by a special committee of independent directors of the Company, the Company had entered into an exclusivity arrangement with Altius.

Altius currently beneficially owns and controls, through Altius Resources Inc., 30,937,500 TNR Shares, representing approximately 12.7% of the issued and outstanding TNR Shares on a non-diluted basis, based on 244,081,780 TNR Shares issued and outstanding as of October 6, 2026.

Based on the closing trading price of Altius Shares on the Toronto Stock Exchange on November 10, 2026, the Transaction values TNR at an estimated $122,000,000. This represents an implied consideration paid per TNR Share of approximately $0.48, which is comprised of approximately $0.38 per TNR Share payable in Altius Shares (for aggregate consideration of $97,000,000) and approximately $0.10 per TNR share payable in SpinCo shares (for aggregate consideration of $25,000,000). The estimated value of the Transaction implies a premium of approximately 60% to the closing trading price of TNR Shares on the TSX Venture Exchange on November 10, 2026.

Transaction Highlights

Two-part consideration: TNR shareholders (other than Altius and dissenting shareholders) will receive 0.0072 of an Altius Share and 0.25 of a SpinCo Share for each TNR Share held. Altius will receive SpinCo Shares on its existing TNR Shares on the same basis as other shareholders.

Liquidity in a diversified royalty company: Altius Shares are listed on the TSX.

Altius investment in SpinCo: Altius has agreed to subscribe for SpinCo Shares by way of private placement for gross proceeds of approximately C$2,200,000. Altius will also provide SpinCo with ongoing technical support relating to the Shotgun project and other expected SpinCo project generation activities.

Unanimous Special Committee and Board recommendation: The Transaction has been unanimously recommended by the Special Committee and unanimously approved by the board of directors of TNR Gold (the “Board”), following receipt of an oral fairness opinion from Evans & Evans, Inc., with a written opinion to follow.

Minority shareholder protection: The Transaction is subject to approval by a majority of the votes cast by TNR shareholders, excluding votes attached to TNR Shares held by Altius and its related parties and any other shareholders required to be excluded under Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions.

Support of directors, officers and certain shareholders: All directors and officers of TNR Gold and certain other shareholders, together holding approximately 28.2% of the issued and outstanding TNR Shares, have entered into voting support agreements with Altius.

Kirill Klip, Executive Chairman of TNR Gold, stated: “The Arrangement Agreement with Altius is a pivotal milestone that fully validates the significant value we have created for TNR Gold shareholders. Altius is a premier and highly respected partner in the mining and royalty sector, and this Transaction delivers a compelling outcome for our shareholders, and we are thrilled to be making this announcement.”

Brian Dalton, CEO of Altius commented: “This transaction adds a significant development stage royalty over the Los Azules project, which offers the potential for decades of increased copper exposure within our portfolio. It also results in the consolidation of an operating stage royalty relating to the Mariana lithium brine project. Both of these assets feature attributes that are hallmarks of Altius’s long-term royalty investing strategy. With long to ultra-long potential resource lives, they provide growth optionality over multiple commodity cycles as well as projected cost curve positions that ensure long-term resiliency. We are also pleased to support the SpinCo as it applies the historical project generation and royalty creation strategy that brought the Los Azules and Mariana royalties into its portfolio.”

Transaction Details

The Transaction will be completed by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia). Before the Arrangement becomes effective, TNR Gold will incorporate SpinCo and transfer to it TNR Gold’s 90% interest in 0828073 B.C. Ltd. and certain related intercompany receivables. In addition, Bristol Exploration Co., Inc. will grant a 0.5% net smelter returns royalty on the Shotgun Gold Project to TNR Gold (once it is wholly owned by Altius).

Under the Arrangement, each TNR Share will be exchanged for one Class A share of TNR Gold and 0.25 of a SpinCo Share. Each Class A share held by a shareholder other than Altius will then be transferred to Altius in exchange for 0.0072 of an Altius Share. No fractional shares will be issued.

TNR Gold stock options that are not exercised before the effective time of the Arrangement will be surrendered and cancelled for no consideration. All outstanding options are fully vested. TNR Gold’s shareholder rights plan will terminate under the Arrangement.

On completion of the Arrangement, TNR Gold will become a wholly-owned subsidiary of Altius, and the TNR Shares will be delisted from the TSXV.

The Arrangement Agreement contains customary representations, warranties and covenants for a transaction of this nature, including non-solicitation covenants on the part of TNR Gold, subject to customary “fiduciary out” provisions that entitle TNR Gold to consider and accept a superior proposal, and a five-business-day right in favour of Altius to match any superior proposal. The Arrangement Agreement provides for a termination fee of C$5,000,000 payable by TNR Gold to Altius in certain circumstances, including if the Arrangement Agreement is terminated in connection with TNR Gold pursuing a superior proposal. The Arrangement Agreement also provides for a reverse termination fee of C$5,000,000 payable by Altius to TNR Gold in certain circumstances.

As soon as practicable after the effective time of the Arrangement or such earlier time as the TSXV may require, Altius will subscribe for SpinCo Shares for gross proceeds of approximately C$2,200,000, such that Altius will increase its interest to approximately 19.9% in SpinCo.

There are no finder’s fees payable in connection with the Transaction.

Required Approvals and Timing

The Transaction will be subject to the approval of TNR shareholders at an annual general and special meeting of shareholders, expected to be held on or before December 22, 2026, by: (i) at least 66⅔% of the votes cast by TNR shareholders present in person or represented by proxy at the Meeting; and (ii) a simple majority of the votes cast by TNR shareholders present in person or represented by proxy at the Meeting, excluding the votes required to be excluded under MI 61-101, including the votes attached to TNR Shares held by Altius, Kirill Klip and Konstantin Klip, and by any of their related parties and joint actors whose votes must be excluded under MI 61-101.

Altius is a “related party” of TNR Gold within the meaning of MI 61-101 by virtue of its ownership of more than 10% of the issued and outstanding TNR Shares, and the Transaction constitutes a “business combination” for the purposes of MI 61-101. Kirill Klip and Konstantin Klip will receive change of control payments under their consulting agreements with the Company in connection with the Arrangement, which constitute “collateral benefits” under MI 61-101.

In addition to shareholder approval, completion of the Transaction is subject to the receipt of an interim order and a final order of the Supreme Court of British Columbia, conditional approval of the TSX for the listing of the Altius Shares to be issued under the Arrangement, conditional approval of the TSXV for the listing of the SpinCo Shares, and the satisfaction of certain other closing conditions customary for transactions of this nature. Listing of the SpinCo Shares will be subject to SpinCo’s satisfaction of the listing requirements of the TSXV.

Subject to these approvals and conditions, closing is expected to occur in Q1 2027. Following completion of the Transaction, TNR Gold will apply to cease to be a reporting issuer under applicable Canadian securities laws.

Full details of the Transaction will be set out in the management information circular to be mailed to TNR shareholders in connection with the Meeting. The Circular will include a summary of the Fairness Opinion (as defined below), the background to the Transaction, the Special Committee’s and the Board’s reasons for their recommendations, the MI 61-101 disclosure and prospectus-level disclosure about SpinCo.

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 thirty 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, 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 Lithium 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 Novagold Resources. Following completion of the Arrangement, TNR’s interest in the Shotgun Gold Project will be held by SpinCo.

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.
