Kelowna, British Columbia--(Newsfile Corp. - March 31, 2026) - F4 Uranium Corp. (TSXV: FFU) ("F4" or "the Company") announces that its summer exploration in the Athabasca Basin will focus on the Murphy Lake property located 5km south of the Hurricane Deposit with partner UraniumX Discovery Corp (formerly known as Stearman Resources Inc) and on the wholly-owned Todd Lake and Wales Lake projects located within 25km of Paladin's Triple R and Nexgen's Arrow deposits in the southwest corner of the Athabasca Basin. Drilling at Murphy Lake, where F4 is the operator, is set to begin at the end of May to be funded by UraniumX in accordance with the earn-in agreement on the property (see news release dated July 29, 2025) and to be followed by the work at Todd Lake and Wales Lake in the region where a string of recent discoveries, including F3 Uranium's JR Zone and Tetra Zone, Nexgen Energy's PCE occurrence, and Paladin Energy's Saloon area, highlight the potential for additional uranium discoveries (see map 1 below).

The Company holds all necessary work permits for the three planned exploration programs. The Todd Lake and Wales Lake programs, with a combined budget of $1.5 million, remain subject to financing.

Todd Lake
F4's westside flagship Todd Lake property is located 14km southwest of Paladin's Triple R and Nexgen's Arrow deposits. These major deposits are located within the Patterson Lake conductive corridor which strikes southwest towards Todd Lake and where an airborne Mobile MagnetoTellurics (Mobile MT) survey completed in summer 2025 identified possible extension to the PLC and the Carter Trends into the Todd Lake property (see F4 news release dated July 2, 2025). The property lies within the Clearwater Domain, an underexplored geological unit with no historic ground geophysics or drilling completed, and where F3 Uranium recently made the Tetra Zone discovery, less than 4km northeast of Todd lake. Map 1 below shows the location of Todd Lake in relation to the Tetra Zone discovery and to the Paladin Triple R and Nexgen Arrow uranium deposits. Planning of the summer exploration work on Todd Lake, including drilling, is in progress.

Wales Lake
F4's Wales Lake Project is located outside the southwest Athabasca Basin within 25km of Paladin's Triple R and Nexgen Energy's Arrow deposits. The project lies southwest of the Dirkson and Saloon Trends, host to both Nexgen Energy's PCE uranium occurrence and Paladin Energy's recently discovered Saloon East (see Map 1). With F3 Uranium's discovery in 2025 of the Tetra Zone in the Clearwater Domain, F4 believes in a diverse exploration potential on the Wales Project. The properties are significantly underexplored with only 4 previous drillholes and planning of the next steps for summer 2026 exploration work on the Wales Lake project is underway.
