F4 Searches for Patterson Lake Corridor at Wales Lake

F4 Uranium Corp. has initiated an airborne Mobile MagnetoTellurics (Mobile MT) survey across the western section of its Wales Lake Project in Saskatchewan. The program encompasses approximately 700 line kilometres and is designed to identify extensions of the Patterson Lake Corridor (PLC) and the parallel Saloon Trend, geological features that host major uranium deposits operated by NexGen Energy and Paladin Energy.

The survey is fully funded through a brokered private placement that closed on July 9, 2026, raising gross proceeds of C$1.0 million. The Wales Lake property is 100% owned, permitted, and drill-ready, yet remains highly underexplored with only two historic drillholes completed to date.

This development follows the completion of a 4,092-metre drill program at the partnered Murphy Lake property on July 7, 2026, which successfully defined two prospective mineralized corridors.

F4 Uranium Corp. (FFU) has begun its Wales Lake survey, marking an expected, incremental step in the company's 2026 summer exploration program. The program, initially outlined in March 2026, carries a combined $1.5 million budget for Todd and Wales Lake, pending financing. A July 9 financing secured the necessary capital to execute this phase of work.

The market was aware of the planned summer program and the subsequent financing, making this a routine execution update rather than a new catalyst. The stock has traded in a tight consolidation range between $0.11 and $0.12 since mid-July, indicating that the news has been absorbed without significant price discovery. While the announcement is positive for maintaining exploration momentum and validating the company's targeting model, it does not contain material new financial data, discoveries, or strategic shifts.

F4 Uranium Corp. is a pre-revenue junior explorer spun out from F3 Uranium in August 2024, focusing on the acquisition and evaluation of high-grade uranium properties in Saskatchewan's Athabasca Basin. The company’s portfolio spans approximately 17 properties, strategically clustered within 2-110 km of major uranium operations including Cigar Lake, Hurricane, Triple R, and Key Lake, providing access to established mining infrastructure.

Key projects include Murphy Lake, where the company partnered with UraniumX Discovery Corp. Drilling completed in July 2026 defined two prospective trends. The company also owns 100% of Todd Lake, where an airborne MT survey completed in December 2025 identified PLC extensions. Additionally, the underexplored Wales Lake property, which contains only two historic drillholes, is set to begin an airborne survey in July 2026.
