Supports Targeting on the Southern Margin of the Athabasca

Basin

Kelowna, British Columbia--(Newsfile Corp. - August 19, 2026) -

F4 Uranium Corp

.

(TSXV: FFU)

(OTCQB: FFUCF)

("

F4

" or the "

Company

") is pleased to announce that it acquired the Kelic Lake

Project ("Kelic Lake" or the "Property") through map staking. Totalling 4,835 ha, the newly staked Kelic

Lake Project straddles the southern margin of the Athabasca Basin in northern Saskatchewan,

approximately 55 km southeast of NexGen Energy's Arrow and Paladin's Triple R deposits and 43km

southwest of Cameco's Centennial deposit. Historical drilling has intersected key structural and

lithological features critical to the Company's Athabasca Uranium targeting model, including extensive

Athabasca Sandstone alteration and faulting, thick graphitic and sulphide-bearing basement rocks, and

anomalous uranium near the Athabasca Unconformity.

Kelic Lake adds a project with extensive historical exploration to F4's growing portfolio in the

southwestern Athabasca region, bringing its total portfolio to approximately 124,000 ha across 17

properties. Previous work on the Property includes diamond drilling, airborne and ground

electromagnetic surveys, and gravity and radiometric surveys.

Kelic Lake Highlights:

Strategic Basin-Margin Location: Kelic Lake straddles the southern margin of the Athabasca

Basin, providing exploration potential for both unconformity and basement-hosted uranium

mineralization.

Airborne Geophysics identified corridors: Mag and VTEM surveys completed on the Property in

2005 identified several conductive zones (Figure 1), with the interpreted highest priority zone

trending northwest to southeast and continuing onto the North end of the Kelic Lake Property. An

additional north-south anomaly was noted that corresponded to a major north-south break and

magnetic low (Saskatchewan Assessment Report 74F08-0022).

Historical uranium near the Athabasca Unconformity: Historical drill hole KLL-3 from 1978 returned

anomalous uranium immediately above the unconformity, including two contiguous 0.30 m

sandstone core samples averaging 191 ppm U

O

and 205 ppm Ni over a 0.61 m interval from

99.67 m to 100.28 m depth (327 to 329 feet). Nickel is a common pathfinder element for

unconformity-related uranium mineralization in the Athabasca Basin. Analytical procedures,

laboratory and quality-control measures are not documented in the historical record

(Saskatchewan Assessment Report 74F08-0012).

Strong Alteration and Structure: More recent drilling from 2015 by ALX Uranium Corp intersected

extensive and pervasive bleaching and desilicification of Athabasca sandstone, interpreted by the

previous operator to be related to faulting, along with strong secondary hematization and local

chloritization immediately above the unconformity and thick graphitic gneiss containing locally

abundant graphite and pyrite in basement. Drill hole KL15-006, drilled just north of the Property

claim boundary and approximately 2.5km North of KLL-3, intersected an approximately 7.4-metre

fault zone characterized by highly fractured and broken sandstone, rubble, clay-coated fractures,

local clay gouge, desilicification and brecciation (Saskatchewan Assessment Report

MAW02077).

Erik Sehn, P.Geo., Vice President Exploration, commented:

"

Kelic Lake is F4's first project on the southern margin of the Athabasca Basin, opening a new

exploration front for the Company, and it has many of the key attributes we look for in uranium

exploration: it straddles the southern margin of the Athabasca Basin, has shallow sandstone cover,

ranging from absent outside of the basin margin to less than 200 metres, and has seen extensive

historical exploration. This previous work has already demonstrated many of the core geological

features we consider important when targeting Athabasca uranium deposits, including supportive

geophysics, drill-confirmed graphitic structures, widespread bleaching and desilicification of the

sandstone, and, importantly, anomalous uranium, including 191 ppm U

O

over 0.61 m in historical

drill hole KLL-3. Our technical team will now thoroughly compile, review and analyze this extensive

historical dataset which contains all of the components required for drill targeting, ahead of the first F4

drilling program on the Property."

About the Kelic Lake Project:

F4 Uranium's 100%-owned, 4,835-hectare Kelic Lake Project straddles the southern margin of the

Athabasca Basin, approximately 55 km southeast of NexGen Energy's Arrow deposit. The Project has

seen extensive historical exploration, including multiple geophysical surveys and diamond drilling

programs, graphitic basement conductors, widespread sandstone alteration and anomalous uranium

including 191 ppm U

O

over 0.61 m in historical drill hole KLL-3.

neighbouring properties is not necessarily indicative of mineralization on the Kelic Lake Project. The

historical exploration results reported herein were obtained by previous operators. The Qualified Person

has reviewed the Saskatchewan assessment reports for the historical drilling described herein, including

the drill logs and the assay data presented in those reports. The Qualified Person has not verified those

results against original assay certificates and has not re-sampled the historical drilling. The analytical

About F4 Uranium Corp:

F4 Uranium is a Canadian uranium exploration company focused on the Athabasca Basin in northern

Saskatchewan, led by the management and exploration team behind multiple uranium discoveries in the

Basin, including most recently Patterson Lake North and Broach Lake. The project portfolio comprises

17 wholly owned properties totalling approximately 124,000 hectares, several of which sit near

established uranium deposits including Paladin's Triple R, NexGen Energy's Arrow and IsoEnergy's

Hurricane. The assets were spun out of F3 Uranium in 2024. F4's exploration program is split between

the west and east sides of the Athabasca Basin, with the Company operating as both an explorer and

project generator providing investors early-stage exposure to the Basin.
