Vancouver, June 1, 2026 - Uranium One Mining Corp. ("Uranium One") (CSE: UUU | OTC: UUUFF | FWB: SL5) and Copper One Resources Corp. ("Copper One") (CSE: CEXY | OTC: CEXYF | FWB: YW5) (collectively, the "Companies") are pleased to announce that, further to the news release dated May 1, 2026, Copper One has completed the acquisition (the "Acquisition") of a 100% undivided legal and beneficial interest in nine mineral claims known as the Redonda Copper property located northeast of Campbell River in the Vancouver Mining Division of British Columbia (the "Property") from Uranium One, pursuant to the terms of a property purchase agreement (the "Agreement") dated April 30, 2026. All mineral titles comprising the Property were transferred to Copper One on May 11, 2026 pursuant to the Acquisition.

Transaction Terms

Pursuant to the terms of the Agreement, Uranium One transferred to Copper One a 100% interest in the Property, free and clear of all encumbrances other than a 3% net smelter return royalty in favour of Homegold Resources Ltd. ("Homegold") on commencement of commercial production (the "Homegold NSR") and other permitted encumbrances as set out in the Agreement. As consideration, Copper One paid to Uranium One the sum of C$1,100,000 (the "Consideration Cash"). Copper One has assumed all obligations in respect of the Homegold NSR.

All closing conditions have been satisfied including, without limitation, (a) the payment by Uranium One of its outstanding deferred balance of C$300,000 to Homegold, (b) the delivery by Uranium One of all duly executed instruments of transfer necessary to transfer its interest in the Property to Copper One, including all documents required to initiate a bill of sale process on the Mineral Titles Online system in connection with such transfer, (c) the receipt by each party of all necessary consents and approvals, (d) each party's representations and warranties in the Agreement being true and correct in all material respects as of the closing date, and (e) each party completing its covenants and obligations as contained in the Agreement.

As David Greenway is a director and officer of both Uranium One and Copper One, the Acquisition is considered a "related party transaction" as this term is defined in Multilateral Instrument 61-101 - Protection of Minority Securityholders in Special Transactions ("MI 61-101"). Uranium One and Copper One have relied on the exemption from valuation requirement and minority approval pursuant to subsections 5.5(a) and 5.7(1)(a) of MI 61-101, respectively, as the Consideration Cash does not represent more than 25% of either Uranium One or Copper One's market capitalization, as determined in accordance with MI 61-101.
