McEwen Inc. (NYSE: MUX) (TSX:MUX) and Canadian Gold Corp. (TSX-V:CGC) are pleased to announce that they have entered into a binding letter of intent on July 27, 2025 in respect of a proposed transaction, whereby McEwen would acquire all of the issued and outstanding securities of Canadian Gold by way of plan of arrangement. If the Proposed Transaction is completed, Canadian Gold would become a wholly-owned subsidiary of McEwen.

Canadian Gold’s principal asset is its 100% interest in the Tartan Mine, which is located in Manitoba, Canada. The Tartan Mine is a high-grade former producing mine with existing infrastructure and high exploration potential. Canadian Gold also holds a 100% interest in greenfield exploration properties in the Hammond Reef and Malartic South projects, which are adjacent to some of Canada’s largest gold mines and development projects in Ontario and Quebec.

The Proposed Transaction

Pursuant to the terms of the Proposed Transaction, each Canadian Gold common share would entitle its holder to receive 0.0225 of a McEwen common share. The Exchange Ratio represents an offer price of CDN $0.35 per Canadian Gold Share, being a premium of 26% to the 30-day volume weighted average price of the Canadian Gold Shares as at market close on July 25, 2025. Following completion of the transaction, existing Canadian Gold shareholders will own approximately 8.2% of the combined company resulting from the Proposed Transaction.

The LOI provides for the parties to enter into a definitive arrangement agreement setting out the final terms and conditions of the Proposed Transaction. Upon the execution of the Arrangement Agreement, McEwen and Canadian Gold will issue a subsequent news release containing any additional terms of the Proposed Transaction.

Benefits of the Transaction for Canadian Gold Shareholders:

• Ability to fund development and construction of the Tartan Mine with McEwen’s existing financial resources;
• Access to McEwen’s technical team with a strong track record in gold exploration, underground mining and mine development;
• Exposure to McEwen’s diversified portfolio of commodities, producing operations, development projects and royalties; and
• An attractive premium of approximately 26% to the 30-day VWAP of the Canadian Gold Shares and the enhanced liquidity of McEwen Shares from dual stock exchanges listings within the US and Canada.

Benefits of the Transaction for McEwen Shareholders:

• Adds an increasingly rare, high-grade former producing mine in Canada with existing infrastructure. Situated close to Flin Flon, Manitoba (Fig. 1), the Tartan Mine benefits from access to a skilled mining workforce and does not require the construction of a mining camp.
• Proposed development of the Tartan Mine has many similarities to McEwen’s Fox Complex (ramp access, mining method and proposed process plant design), leveraging McEwen’s internal skills;
• Enhances McEwen’s development and production pipeline with the potential to re-commence production at the Tartan Mine within 24 to 36 months; and
• Substantial exploration potential, which has been recently increased by Canadian Gold’s optioning of the adjoining Tartan West property (Fig. 2, 3 & 4).

“I am enthusiastic about the Tartan Mine for several reasons. First, it is a high-grade gold deposit with strong exploration potential in Canada. Second, the existing infrastructure, including the mine ramp, roads, and power, provides an opportunity to restart operations within a relatively short timeframe. Third, Manitoba stands out as one of the world’s premier mining jurisdictions, offering a skilled workforce, low-cost renewable energy, and attractive mining tax credits. Additionally, the Tartan Mine shares many similarities with our Fox Complex, enabling us to leverage our internal expertise and resources to maximize its potential,” said Rob McEwen, Chairman and Chief Owner of McEwen Inc.

“I’d like to thank Mr. McEwen, McEwen Inc. and all our shareholders for the support of Canadian Gold Corp. over the past several years. We believe that this acquisition by McEwen is a fantastic result for our shareholders as we will benefit from a broader portfolio of high-quality assets,” said Peter Shippen, Chairman of Canadian Gold Corp.

Details of the Proposed Transaction

• The Proposed Transaction is expected to be completed by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia). Under the terms of the LOI, McEwen will acquire all of the issued and outstanding Canadian Gold Shares in exchange for McEwen Shares on the basis of the Exchange Ratio. Outstanding options and warrants to purchase Canadian Gold Shares would be exercisable prior to the closing of the Proposed Transaction, in accordance with their respective terms. Any outstanding options and warrants not duly exercised prior to the Closing would be terminated without any additional compensation.
• In order to comply with NYSE rules, Mr. Rob McEwen will not be entitled to receive newly-issued shares of McEwen representing more than 1% of the currently issued and outstanding shares of McEwen without obtaining the prior approval of McEwen shareholders, which is expected to be voted on at the next annual meeting of McEwen shareholders. If such shareholder approval is not obtained, McEwen will pay for such excess shares in cash.
• To be effective, the Proposed Transaction will require the approval of: (a) 66 ⅔% of the votes cast by shareholders of Canadian Gold; and, (b) a simple majority of the votes cast by minority Canadian Gold shareholders in accordance with Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions, at a special meeting of Canadian Gold shareholders expected to take place by the end of 2025. In accordance with MI 61-101, the vote of the minority Canadian Gold shareholders will exclude, among others, the shares of Canadian Gold held by McEwen and Mr. Rob McEwen.
• The Arrangement Agreement will include provisions such as conditions to closing the Proposed Transaction, and representations and warranties and covenants customary for arrangement agreements. The LOI stipulates that the Arrangement Agreement will also include: (i) customary deal protection and non-solicitation provisions in favor of McEwen, including a break fee of approximately C$2.2 million payable to McEwen in certain circumstances; and (ii) provisions allowing Canadian Gold to consider and accept superior proposals, in compliance with its fiduciary duties.
• Completion of the Proposed Transaction will be subject to customary closing conditions and receipt of necessary court and regulatory approvals, including approval of the TSX and the NYSE.

A copy of the LOI will be filed on McEwen’s and Canadian Gold’s SEDAR+ profiles at www.sedarplus.ca.

The Proposed Transaction was approved by the Board of Directors of both McEwen and Canadian Gold, based on the recommendation of their respective special committees comprised of independent and disinterested directors. These special committees reached their decisions after consulting with their independent legal and financial advisors.

Messrs. Rob McEwen and Ian Ball, recognizing their respective conflicts of interest as directors of McEwen and as shareholders/interested parties in Canadian Gold, abstained from voting on the approval of the Proposed Transaction by McEwen’s Board of Directors. Similarly, Messrs. Alexander McEwen and Jim Downey acknowledged their conflicts of interest, as they were appointed to the Canadian Gold Board of Directors by Rob McEwen.

To ensure a thorough and impartial review of the Proposed Transaction, the special committees of both companies have engaged independent financial advisors. These advisors will prepare a formal valuation of the respective shares, as required by securities law, and provide an opinion that, subject to the assumptions, limitations, and qualifications outlined in the written opinion, the consideration to be exchanged is fair from a financial perspective.

Further details with respect to the Proposed Transaction will be included in the Arrangement Agreement and in an information circular to be mailed to Canadian Gold shareholders in connection with the Canadian Gold Meeting. Once available, a copy of the Arrangement Agreement will be filed on each of McEwen’s and Canadian Gold’s SEDAR+ profiles at www.sedarplus.ca and a copy of the information circular will be filed on Canadian Gold’s SEDAR+ profile at www.sedarplus.ca.

Overview of Canadian Gold’s Tartan Mine

The Tartan Mine is a former producing mine with significant infrastructure close to the town of Flin Flon, Manitoba. It has access to a skilled workforce, inexpensive renewable power and a supportive mining and taxation environment.

Tartan Mine produced 47,000 ounces of gold between 1987 and 1989. Recently, Canadian Gold announced two transactions that expanded the strike length of Tartan from 8 kilometers to 29.5 kilometers along a key regional shear zone. The expanded property has the benefit of leveraging the infrastructure at Tartan Mine that includes a ramp to 320 meters below surface, the footprint of the former 450 tpd mill, road access and power to the mine site.
