F3 Files NI 43-101 Technical Report for Previously Announced Initial Indicated Mineral Resource
F3 Uranium Formalizes Maiden Resource While Shifting High-Stakes Exploration Focus to the Tetra Discovery
On January 20, 2026, F3 Uranium Corp filed an independent NI 43-101 technical report for the initial indicated mineral resource estimate (MRE) at the JR Zone of its 100% owned Patterson Lake North (PLN) Property. This report formalizes the data previously released on December 22, 2025. The MRE, prepared by SLR International Corporation, identifies an indicated resource of 11.8 million pounds of $U_3O_8$ at an average grade of 4.39%, including a high-grade domain of 10.8 million pounds at a staggering 12.23% $U_3O_8$.
The filing is a mandatory regulatory step and does not change the resource figures announced in December. While the grades are world-class (12.23% in the high-grade core), the total scale of the JR Zone (11.8M lbs) remains modest compared to neighboring Tier-1 deposits like NexGen’s Arrow or Fission’s Triple R.
The materiality of the current news is "Routine - Positive" because: - It confirms the technical viability of the JR Zone. - It provides the necessary documentation required for the company’s pending Nasdaq listing application. - It allows management to officially pivot the exploration narrative toward the Tetra Zone, which is currently the company’s primary speculative catalyst.
F3 Uranium focuses on the southwestern edge of the Athabasca Basin in Saskatchewan. Its flagship Patterson Lake North (PLN) project is located near two of the world's largest undeveloped high-grade uranium deposits. - JR Zone: The first discovery, now a defined resource of 11.8M lbs. - Tetra Zone: Located 13km south of JR Zone, currently in the exploration/discovery phase with high-grade potential indicated by scintillometer readings.
