F4 SEARCHES FOR PATTERSON LAKE CORRIDOR AT WALES LAKE

F4 Uranium Corp. has commenced an airborne mobile magnetotelluric (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 30 kilometres to the northeast of the Wales Lake project. Following the closing of a brokered private placement for gross proceeds of $1-million (see news release dated July 9, 2026), this program is being financed 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 that hosts both NexGen Energy's Arrow (30 kilometres to the northeast) and Paladin's Triple R deposits (22 kilometres to the northeast). In addition, the PLC is accompanied by the parallel Saloon trend, which hosts Paladin Energy's newly announced Atlas discovery (20 kilometres to the northeast), its high-grade Saloon discovery from 2024 and NexgGen Energy's Patterson Corridor East (PCE) discovery. Both highly prospective corridors are interpreted to trend down toward 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 and the Carter trends within the Clearwater domain (see news release dated Dec. 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, PGeo, 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 per cent owned, permitted and drill ready with strong airborne and ground conductor targets. Significantly underexplored with only two historic drill holes, the Wales Lake project is located just outside of the southwestern Athabasca basin within 25 kilometres 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-per-cent-owned Todd Lake project is located 14 kilometres 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 four kilometres 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 totalling 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 western and eastern sides of the Athabasca basin, with the company operating as both an explorer and project generator, providing investors early-stage exposure to the basin.
