F4 and UraniumX Commence Drilling at Murphy Lake

• F4 Uranium Corp. has officially commenced a ~2,500-metre drilling program at its Murphy Lake Property in the Athabasca Basin.
• The program is fully funded by partner UraniumX Discovery Corp under an existing option agreement, with costs estimated at approximately $2M CAD.
• Drilling targets areas identified through 2026 MLEM surveying and foundational 2022 maiden drilling results (Target Area 1).
• F4 aims to earn up to a 70% interest in the Murphy Lake Property under the option agreement terms.
• The company has extended its marketing services agreement with Connect 4 Marketing Ltd for an additional two months at $50,000 CAD.
• Historical data referenced includes hole ML22-012 (56 ppm U) and ML22-006 (0.065% U3O8 over 2.5 m).

• The news confirms the execution of a previously announced plan; the May 5, 2026 release stated drilling would commence mid-May 2026.
• Funding is secured via the partner agreement, removing immediate capital raising risk for this specific program.
• No assay results or new mineralization discoveries are disclosed in this release, limiting immediate upside potential relative to market expectations.
• The announcement validates operational progress but does not alter the fundamental valuation thesis beyond confirming activity continues as planned.
• There is a notable discrepancy in partner identification between historical news (Stearman Resources Inc., Feb 2026) and current news (UraniumX Discovery Corp, May 2026), which introduces uncertainty regarding the stability of the funding arrangement despite the positive operational update.

• F4 Uranium Corp. is an exploration company focused on uranium properties in the Athabasca Basin, Saskatchewan.
• Flagship Project: Murphy Lake Property (609 hectares), located 5 km south of IsoEnergy's Hurricane Deposit and 4 km east of Cameco's La Rocque Lake Zone.
• Other Projects: Todd Lake (wholly owned, Clearwater Domain) and Wales Lake (wholly owned, ~40,113 ha).
• The Murphy Lake project is the primary focus for near-term drilling due to partnership funding, while Todd and Wales Lake require external financing.
