F4 Uranium to conduct geophysics work at Murphy Lake

Mr. Raymond Ashley reports F4 AND URANIUMX ANNOUNCE GEOPHYSICS AT MURPHY LAKE F4 Uranium Corp. plans to commence ground EM geophysics at Murphy Lake, five kilometres south of IsoEnergy's high-grade Hurricane deposit and four kilometres east of Cameco's La Rocque Lake uranium zone. EarthEx Geophysical Solutions will complete four lines totalling 9.2 line kilometres of moving-loop electromagnetics; this MLEM will build on previous ground geophysics by tightening the survey line spacing -- testing the areas around and between two known prospective conductor systems as previously identified by F4. The results will be integrated into the project model to guide the upcoming drill program which is planned for late spring of 2026. The Murphy work program is being financed by UraniumX Discovery Corp. in accordance with the terms of the option agreement to acquire up to a 70-per-cent interest in the Murphy Lake property (see F4 news release dated Feb. 2, 2026); F4 will be the operator during the earn-in period. Drilling by F4 in 2022 intersected strongly elevated uranium geochemistry and indicators commonly associated with uranium mineralization including intense hematite and limonite alteration in sandstone and graphitic shear zones in the basement. The program was highlighted by drill hole ML22-006 which hit 0.242 per cent U3O8 (triuranium octoxide) and a 4.2-metre-wide deformation zone. A total of 1.4 kilometres away at the northern end of the property, ML22-012, was interpreted to have just overshot the conductive basement target -- but intersected strong 56 part per million uranium in a 0.5 m sandstone sample just above the unconformity. Erik Sehn, vice-president of exploration, commented: "F4 Uranium considers Murphy Lake to be one of its best exploration properties considering its strong early indicators, and close proximity to major uranium discoveries including IsoEnergy's Hurricane and Cameco's La Rocque Lake project. Along with our partners UraniumX, we look forward to completing this geophysical program to assist in target generation for the next drill program. This has been a project that the team has been eager to return to since 2022, and this geophysical program is an important step before we start further drill testing the areas around ML22-006 -- where we hit uranium mineralization in 2022, and ML22-012 where we have very strong and favourable alteration and geochemistry 1.4 km away." About Murphy Lake F4's 609-hectare Murphy Lake property is located in the northeastern corner of the Athabasca basin, 30 km northwest of Orano's McLean Lake deposits, five km south of ISOEnergy's Hurricane uranium deposit and four km east of Cameco's La Rocque Lake uranium zone where drill hole Q22-040 intersected 29.9 per cent U3O8 over 7.0 m. The 2022 maiden drill program at the Murphy Lake property consisted of 14 completed drill holes totalling 6,850 m; drill hole ML22-006 intersected 0.065 per cent U3O8 over 2.5 m from 322.5 m to 324.5 m, including 0.242 per cent U3O8 over 0.5 m.

This news release also refers to neighboring properties in which F4 Uranium has no interest, and the qualified person has been unable to verify the information from those properties. Mineralization on those neighbouring properties is not necessarily indicative of mineralization on the Murphy Lake property.

About F4 Uranium Corp. F4 Uranium is a Canadian uranium exploration company focused on the Athabasca basin in Northern Saskatchewan, and the latest uranium explorer, lead by the same management and exploration team with a legacy of discovery successes. The project portfolio includes 17 wholly owned properties totalling roughly 157,000 hectares, many of which are near uranium deposits including Paladin's Triple R, Nexgen Energy's Arrow and IsoEnergy's Hurricane projects. The assets were spun out of F3 Uranium in 2024, where the technical and management team made their third, and more recently fourth uranium discoveries at Patterson Lake North and Broach Lake. F4's core focus will be split between the west and east sides of the Athabasca basin as the company is establishing itself as an explorer and project generator providing shareholders renewed exposure at an early stage.
