F4 AND URANIUMX ANNOUNCE FIELD PROGRAM UNDERWAY AT MURPHY LAKE

F4 Uranium Corp.'s partner-financed ground EM geophysics program at Murphy Lake is now under way (see F4 news release dated Feb. 17, 2026). The property is located five kilometres south of IsoEnergy's high-grade Hurricane deposit and four kilometres east of Cameco's La Rocque Lake uranium zone.

The geophysics crew has mobilized to the highest-priority northernmost lines near historic drill hole ML22-012. This hole is interpreted to have overshot the conductive basement target but returned strong uranium geochemistry just above the Athabasca unconformity, highlighted by 56 ppm (parts per million) U (uranium) over 0.5 metre in sandstone. These lines will also test for an extension of the north-south conductive corridor where ML22-006 intersected 0.242 per cent U3O8 (triuranium octoxide) in basement rocks within a 4.2-metre-wide deformation zone.

The new EM results will be integrated into the project model as the data is received and interpreted, helping to guide the upcoming drill program planned for late spring 2026.

The Murphy Lake work program is being fully financed by UraniumX Discovery Corp. in accordance with the terms of the option agreement to earn up to a 70-per-cent interest in the Murphy Lake property (see F4 news release dated Feb. 2, 2026). F4 will act as operator during the earn-in period.

About Murphy Lake

F4's 609-hectare Murphy Lake property is located in the northeastern corner of the Athabasca basin, 30 kilometres 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 drill program at the Murphy Lake property consisted of 14 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.

About F4 Uranium Corp.

F4 Uranium is a Canadian uranium exploration company focused on the Athabasca basin in Northern Saskatchewan company is led by a 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 project portfolio includes 17 wholly owned properties totalling roughly 157,000 ha, 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.
