Program
Kelowna, British Columbia--(Newsfile Corp. - July 21, 2026) -
F4 Uranium Corp
.
(TSXV: FFU)
("
F4
" or
the "
Company
") is pleased to announce the commencement of an airborne Mobile MagnetoTellurics
(Mobile MT) survey over the western portion of its Wales Lake Project, located just outside of the
southwestern Athabasca Basin, in search of the Patterson Lake Corridor (PLC) on Wales Lake. The
PLC and its associated parallel trends host two major uranium deposits and three recent high-grade
discoveries within 30km to the northeast of the Wales Lake Project. Following the closing of a brokered
private placement for gross proceeds of C$1.0 million (see news release dated July 9, 2026), this
program is being funded from the placement and is the first phase of work on F4's western Athabasca
portfolio which includes Todd and Wales Lake and will be the focus of summer exploration in 2026.
The Patterson Lake Corridor (PLC) is a prolific conductive corridor which hosts both NexGen Energy's
Arrow (30km to the northeast) and Paladin's Triple R deposits (22km to the northeast). In addition, the
PLC is accompanied by the parallel Saloon Trend which hosts Paladin Energy's newly announced Atlas
discovery (20 kms to the northeast), their high-grade Saloon discovery from 2024 and NexgGen
Energy's Patterson Corridor East (PCE) discovery (Figure 1). Both highly prospective corridors are
interpreted to trend down towards and potentially through F4's Todd and Wales Lake Projects and
locating them across the Todd and Wales Properties is the Company's primary objective in the near
term.
In 2025, F4 completed the same airborne MT survey on its Todd Lake Project, which already identified
possible extensions to the Patterson Lake Corridor (PLC) and the Carter Trends within the Clearwater
Domain (see news release dated December 15, 2025). Now in 2026 F4 has contracted Expert
Geophysics Surveys Inc. to complete the same survey, which will consist of approximately 700 line
kilometres of flying, with the goal of determining if the trends observed on the Todd property continue
onto the western extent of the Wales Lake property. The program marks the first work of summer 2026
on F4's Western Athabasca portfolio with plans for additional work on Todd Lake and Wales Lake in the
coming months.
Erik Sehn, P.Geo., Vice President Exploration, commented:
"
We're excited to kick off our 2026 summer program at Wales Lake. The story here comes down to two
of the most prolific corridors in the western Athabasca — the Patterson Lake Corridor, which hosts
NexGen's Arrow and Paladin's Triple R deposits, and the parallel Saloon Trend, home to Paladin's
new Atlas discovery and NexGen's Patterson Corridor East. Both are interpreted to trend toward our
ground, and we suspect they carry on through the Wales Lake Project. Our near-term objective is
straightforward — to locate these corridors across our Todd and Wales properties. Last year's Mobile
MT survey at Todd Lake picked up resistivity-low trends that line up with the interpreted strike of the
Patterson Lake Corridor, and those same features appear to continue toward the western end of Wales
Lake. The nearby Tetra Zone discovery, just four kilometres northeast of Todd Lake in the Clearwater
Domain, already shows this setting can host high-grade uranium mineralization. This airborne survey
is the first step: mapping the corridors geophysically from the air. Based on the results, we will tighten
up those targets with ground geophysics, before moving to drill-testing the most prospective of them.
With our recently closed financing in place, we're well positioned to move quickly through advancing
Wales Lake and the rest of our western Athabasca portfolio this year."

About the Wales Lake Project:
F4 Uranium's 40,113-hectare Wales Lake Project consists of the Wales Lake East and Wales Lake
West properties, both 100% owned, permitted and drill ready with strong airborne and ground conductor
targets. Significantly underexplored with only two historic drillholes, the Wales Lake Project is located
just outside of the Southwestern Athabasca Basin within 25km of Paladin's Triple R and NexGen
Energy's Arrow deposits. A series of recent discoveries including F3 Uranium's JR and Tetra Zones,
NexGen Energy's PCE occurrence, and Paladin Energy's Saloon area further highlight the uranium
discovery potential near the Southwestern Athabasca Basin.
Wales Lake is accessed by Provincial Highway 955, which transects the property.
About the Todd Lake Project:
F4 Uranium's 100% owned Todd Lake Project is located 14km Southwest of Paladin's Triple R and
Nexgen Energy's Arrow deposits and lies along trend of the Patterson Lake corridor which hosts the
aforementioned deposits. Significantly underexplored with no historic drilling, the Todd Lake Project is
located just outside of the Southwestern Athabasca Basin. A series of recent discoveries including
Nexgen Energy's PCE occurrence, Paladin Energy's Saloon area and F3 Uranium's JR and Tetra
Zones, the latter located just 4km Northeast of the top of Todd Lake, further highlight the uranium
discovery potential near the Southwestern Athabasca Basin. Todd Lake is accessed by Provincial
Highway 955, located to the east of the property.

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
16 wholly owned properties totaling approximately 157,000 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.
