F3 Begins 3,000 Meter Fall Drill Program at Tetra Zone

Executive Summary

• F3 Uranium Corp. announced a 3,000‑metre fall diamond‑drill program at the 100 % owned Broach Lake Property targeting the newly discovered high‑grade Tetra Zone.
• The program will test the extent of uranium mineralization highlighted by recent holes PLN25‑205 (1.0 m @ 2.50 % U₃O₈ within a 22.5 m interval averaging 0.26 % U₃O₈) and PLN25‑217 (67 m composite anomalous radioactivity, including 49 m continuous).
• Ground EM surveying is complete; 3‑D inversions are underway to refine the targeting model for regional strike‑parallel drilling.

Key Details

• Drill Program: Approximately 3,000 m of diamond drilling scheduled for fall 2025.
• Target Zone: Tetra Zone on Broach Lake Property (part of the Patterson Lake North Project).
• Recent Intercepts:
• PLN25‑205: 1.0 m @ 2.50 % U₃O₈; within a 22.5 m mineralized interval averaging 0.26 % U₃O₈.
• PLN25‑217: 67 m composite anomalous radioactivity, including 49 m of continuous radioactivity.
• Geophysical Work: Ground EM survey completed; 3‑D inversion modeling in progress to support drill targeting.
• Assay Thresholds Defined by Company: >1.0 % U₃O₈ = “high grade”; >20.0 % U₃O₈ = “ultra‑high grade”.
• Radiation Measurement Protocol: Handheld Radiation Solutions RS‑125 spectrometer; >300 cps flagged as anomalous, >10,000 cps as highly radioactive, >65,535 cps off‑scale.
• Project Context: The Patterson Lake North (PLN) Project comprises 42,961 ha in the Athabasca Basin, adjacent to Paladin’s Triple R and NexGen’s Arrow deposits. It includes:
• JR Zone discovery on the 4,074‑ha Patterson Lake North Property.
• Minto Property (19,864 ha).
• Broach Property (19,022 ha) hosting Tetra Zone.
• Qualified Person: Raymond Ashley, P.Geo., President & COO of F3 Uranium Corp., reviewed and approved the technical information per NI 43‑101.
