GREENCASTLE ANNOUNCES ACQUISITION OF COMMON SHARES OF ROYAL URANIUM

Greencastle Resources Ltd. has entered into a share purchase agreement dated Nov. 18, 2025, with an arm's-length third party, pursuant to which the company will acquire an aggregate of 500,000 common shares in the capital of Royal Uranium Inc. Prior to the acquisition of the purchased shares, the company did not hold any securities of Royal Uranium.

As consideration for the purchased shares, the company will issue 3.5 million common shares from treasury at a deemed price of five cents per share for an aggregate deemed value of $175,000. No cash consideration is payable.

The acquisition is being completed for investment purposes and is consistent with the company's strategy to pursue selective positions in prospective resource companies and projects. Royal Uranium holds a portfolio of 18 uranium royalties across the Athabasca basin, Newfoundland, the advanced-stage Berlin project, located in Colombia, gas royalties in Wyoming and Oklahoma, and a revenue-generating coal bed methane gas royalty in Alberta. The company believes that Royal Uranium's exposure to uranium and oil and gas opportunities offers attractive leverage to the commodity cycle and complements the company's broader portfolio focus.

Closing of the acquisition remains subject to customary conditions, including receipt of all necessary corporate approvals and acceptance of the TSX Venture Exchange for the issuance of the consideration shares.

The consideration shares will be issued under applicable Canadian securities laws and will be subject to a statutory hold period of four months and one day from the date of issuance. The consideration shares are expected to be listed for trading on the TSX-V upon expiry of the hold period, subject to TSX-V acceptance and compliance with applicable listing requirements.

The vendor is arm's length to the company within the meaning of applicable securities laws. No finders' fees or commissions are payable in connection with the acquisition. The acquisition does not constitute a related-party transaction under Multilateral Instrument 61-101 (Protection of Minority Security Holders in Special Transactions).

We seek Safe Harbor.
