F4 Searches for Patterson Lake Corridor at Wales Lake
Rhea-AI Summary
F4 Uranium (TSXV: FFU; OTC: FFUCF) announced the start of an airborne Mobile MagnetoTellurics (Mobile MT) survey over the western portion of its 40,113-hectare Wales Lake Project in the southwestern Athabasca region. The work, contracted to Expert Geophysics Surveys, will cover approximately 700 line kilometres and seeks to locate extensions of the Patterson Lake Corridor (PLC) and parallel Saloon Trend across F4's 100%-owned Todd Lake and Wales Lake properties.
According to F4 Uranium, the program is the first phase of its 2026 western Athabasca exploration, funded from a recently closed C$1.0 million brokered private placement. A 2025 Mobile MT survey at Todd Lake identified resistivity-low trends interpreted as possible PLC and Carter Trend extensions. Results from the new Wales Lake survey are expected to guide follow-up ground geophysics and eventual drill targeting. Both Wales Lake East/West and Todd Lake are road-accessible via Provincial Highway 955, are significantly underexplored, and lie near major deposits such as Paladin's Triple R and NexGen Energy's Arrow.

First Phase of F4's 2026 Western Athabasca Exploration 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
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."

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.
