F4 Uranium Confirms Termination of Hearty Bay Option Agreement by Traction Uranium

F4 Uranium Corp. announces that it has received formal notice of termination dated July 15, 2026 from Traction Uranium Corp. regarding the mineral property option agreement dated December 9, 2021, relating to the Hearty Bay Property in Saskatchewan's Athabasca Basin. Pursuant to the Option Agreement, Traction has voluntarily terminated the agreement. The termination will become effective on July 30, 2026. As a result, F4 will retain 100% ownership of the Hearty Bay Property.

Raymond Ashley, CEO of F4 Uranium, commented: "We thank Traction for their contributions to the Hearty Bay Project. F4 now holds a 100% interest in this prospective property and will evaluate next steps to advance exploration. We continue to be encouraged by the project's potential and remain focused on discovering the bedrock source of the high-grade mineralized boulder train on Isle Brochet, where assays returned up to 8.23% U3O8. Future exploration may be undertaken by the Company independently or in collaboration with a new strategic partner."

The Hearty Bay Property comprises 7 mineral claims totaling 11,173 hectares on the northern margin of the Athabasca Basin in Saskatchewan, located approximately 20 km west of the Fond-du-Lac uranium deposit. The Property is highlighted by the historic Isle Brochet boulder field, including the Wolfe and Jackfish radioactive boulder trains. These trains contain mineralized boulders with historic assays up to 3.54% U3O8. Prospecting by F3 Uranium in 2019 identified 45 new mineralized boulders returning assays of up to 8.23% U3O8, with more than 24% of samples exceeding 1% U3O8. Recent exploration includes a 14-hole drill program in 2022, subglacial till sampling in 2022-2023, and analysis of 84 till samples in 2024 that identified a uranium dispersal fan and refined ice-flow vectors toward the Athabasca Basin margin. A gravity survey was also completed to generate new drill targets. A winter 2024 drill program to test these targets was limited to a single hole due to poor ice conditions, leaving most targets untested.

The technical information in this news release has been reviewed and approved on behalf of the Company by Sam Hartmann, P.Geo., President & Chief Operating Officer of F4, and a qualified person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.

F4 Uranium is a Canadian uranium exploration company focused on the Athabasca Basin in northern Saskatchewan, led by the management and exploration team behind multiple uranium discoveries in the Basin, including most recently Patterson Lake North and Broach Lake. The project portfolio comprises 16 wholly owned properties totaling approximately 157,000 hectares, several of which sit near established uranium deposits including Paladin's Triple R, NexGen Energy's Arrow and IsoEnergy's Hurricane. The assets were spun out of F3 Uranium in 2024. F4's exploration program is split between the west and east sides of the Athabasca Basin, with the Company operating as both an explorer and project generator providing investors early-stage exposure to the Basin.
