Toronto, Ontario – January 15, 2025 – IsoEnergy Ltd. (TSX: ISO) (OTCQX: ISENF) (“IsoEnergy”) and Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) (“Purepoint”) are pleased to announce that IsoEnergy has exercised its put option (“Put Option”) under the terms of their joint venture (the “Joint Venture”), as announced in a press release dated December 19, 2024. With this strengthened partnership, both companies are now strategically positioned to collaboratively advance the exploration of 10 highly prospective uranium projects spanning over 98,000 hectares in the eastern Athabasca Basin, renowned as one of the world’s most prolific uranium districts.

The exercise of the Put Option establishes a balanced 50/50 ownership structure for the Joint Venture, with Purepoint acquiring 10% of IsoEnergy’s JV interest in exchange for 4 million shares, enhancing IsoEnergy’s exposure to Purepoint’s diverse portfolio and partnerships, including:

• Hook Lake Joint Venture: In partnership with Cameco and Orano, this project is strategically located on the western side of the Athabasca Basin, along the same trend as Fission Uranium’s Triple R and NexGen’s Arrow deposits. Notably, the Spitfire discovery within this joint venture returned 10.3% U₃O₈ over 10.0 metres;
• Smart Lake Joint Venture:  In partnership with Cameco, this project is situated on the western side of the Athabasca Basin, approximately 18 km west-northwest of Hook Lake and 60 km south-southwest of Orano’s historic Cluff Lake Mine. Drilling at Smart Lake intersected 15.4 meters of 147 ppm U at just 200 metres below surface. Purepoint recently announced a $1.2 million drill program for this project; and
• Denare West VHMS Project: Optioned to Foran Mining, this project is strategically located in east-central Saskatchewan, adjacent to and along the same trend as Foran’s flagship McIlvenna Bay Project.

Philip Williams, CEO of IsoEnergy, commented, "The transition to a 50/50 partnership aligns our interests and strengthens our collaboration as we advance some of the most promising uranium assets in the Athabasca Basin. By increasing our equity position in Purepoint, IsoEnergy enhances its exposure to a diverse and strategically valuable portfolio, with a view to ensuring we are positioned to capitalize on their broader exploration successes. IsoEnergy’s equity portfolio is now worth approximately $40 million including positions in Nexgen Energy Ltd., Premier American Uranium Inc., Atha Energy Corp., Jaguar Uranium Corp., Future Fuels Inc., and Purepoint Uranium Group Inc.¹"
