Kelowna, British Columbia–(Newsfile Corp. – March 18, 2026) – F4 Uranium Corp. (TSXV: FFU) (“F4” or “the Company“) is pleased to announce that the partner-funded ground EM geophysics program at Murphy Lake is now underway (see F4 news release dated February 17, 2026). The property is located 5 kilometres south of IsoEnergy’s high-grade Hurricane Deposit and 4 kilometres east of Cameco’s La Rocque Lake Uranium Zone.
The geophysics crew has mobilized to the highest-priority northernmost lines (Figure 1) 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 U over 0.5 metres in sandstone. These lines will also test for an extension of the north-south conductive corridor where ML22-006 intersected 0.242% U₃O₈ 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 funded by UraniumX Discovery Corp. in accordance with the terms of the Option Agreement to earn up to a 70% interest in the Murphy Lake Property (see F4 news release dated February 2, 2026). F4 will act as operator during the earn-in period.

The 2022 drill program at the Murphy Lake Property consisted of 14 drillholes totaling 6,850m; drill hole ML22-006 intersected 0.065% U3O8 over 2.5m from 322.5m to 324.5m, including 0.242% U3O8 over 0.5m.
