<div id="readability-page-1"><article>Drill Program to Commence Mid-MayKelowna, British Columbia--(Newsfile Corp. - May 5, 2026) - F4 Uranium Corp. (TSXV: FFU) (&#34;F4&#34; or &#34;the Company&#34;) is pleased to announce the extension of ground conductors by 1.45 km at the Murphy Lake Property, Athabasca Basin. The partner-funded Moving Loop Electromagnetic (MLEM) ground EM survey, which was previously announced to be in progress (see F4 news release dated March 18, 2026), has now been completed (see F4 news releases dated February 17, 2026 and March 18, 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. Interpretation of the new data is preliminary but very encouraging and shows that the prospective conductor systems have been extended by an additional 1.45 km, significantly increasing the size of the high-priority target area. The new conductor extensions display a strong correlation with basement resistivity lows, particularly in the corridor where drillhole ML22-012 was drilled at the northern end of the survey — which intersected strong uranium geochemistry in Athabasca Sandstone (up to 56 ppm U) immediately above the unconformity (see F3 Uranium news release dated August 10, 2022) — and drillhole ML22-006, which returned a radioactive intercept assaying 0.065% U₃O₈ over 2.5 metres, including 0.242% U₃O₈ over 0.5 metres (see F3 Uranium news release dated August 10, 2022).Drilling at Murphy Lake, where F4 is the operator, is scheduled to commence in the middle of May 2026. The program is 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).Erik Sehn, P.Geo, VP Exploration, commented: &#34;Encouragingly, these early ground EM results are exactly what we hoped to see. The survey successfully extended the conductors into the areas we didn't cover last time, adding a total of 1.45 km of strike length. This greatly expands the prospective corridor along our two key historic drill holes and we are excited to begin drilling in the middle of May with our partner company UraniumX.&#34;<div><img src="https://imageproxy.pbkrs.com/https://images.newsfilecorp.com/files/10832/295832_ced8c95044a2aaa9_002.jpg?x-oss-process=image/auto-orient,1/interlace,1/resize,w_1440,h_1440/quality,q_95/format,jpg" width="550" height="615" original-src="https://imageproxy.pbkrs.com/https://images.newsfilecorp.com/files/10832/295832_ced8c95044a2aaa9_002.jpg"/>Figure 1.

The 2022 maiden drill program at the Murphy Lake Property consisted of 14 completed 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. Marketing Agreement:The Company also announces that it will extend the digital marketing services agreement with Connect 4 Marketing Ltd. (“Connect4”) to provide the Company with comprehensive digital marketing services including content creation (videos ad creatives, landing pages), influencer management, newsletter coordination, and targeted advertising campaigns in both English and German markets.

The project portfolio includes 17 wholly owned properties totaling 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. 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.Forward-Looking StatementsThis news release contains certain forward-looking statements within the meaning of applicable securities laws.
