F3 begins 3,000-metre drill program at Broach Lake

Executive Summary

• F3 Uranium Corp. has launched a 3,000‑metre fall diamond‑drill program on its 100 % owned Broach Lake property targeting the newly discovered high‑grade Tetra zone.
• The program follows recent ground EM surveys and aims to step out from known high‑grade intercepts (PLN25‑205) and extensive radioactivity zones (PLN25‑217).
• Initial drill results highlighted a 1.0 m interval with 2.50 % U₃O₈ within a broader 22.5 m mineralized zone averaging 0.26 % U₃O₈, and a 67 m composite anomalous radioactivity interval (49 m continuous).

Key Details

• Drill Program: 3,000 m of diamond drilling slated for the fall season on the Broach Lake property’s Tetra zone.
• Key Intercepts to Date:
• PLN25‑205: 1.0 m @ 2.50 % U₃O₈ within a 22.5 m interval averaging 0.26 % U₃O₈.
• PLN25‑217: 67 m composite anomalous radioactivity, including 49 m of continuous radioactivity.
• Ground EM Survey: Completed; 3‑D inversions are underway and will feed into the regional targeting model for future strike‑parallel drilling.
• Radiometric Thresholds (hand‑held RS‑125):

• 300 cps = anomalous, >10,000 cps = highly radioactive, >65,535 cps = off‑scale.

• Note: CPS values are preliminary indicators and do not directly correlate with U₃O₈ grades.
• High‑Grade Definition: Assays >1.0 % U₃O₈ are considered high grade; >20.0 % U₃O₈ are ultra‑high grade (company’s internal benchmark).
• Project Context: The Patterson Lake North (PLN) project spans 42,961 ha in the southwestern Athabasca Basin, adjacent to Paladin’s Triple R and NexGen’s Arrow deposits. It comprises:
• JR zone discovery on the 4,074‑ha core property.
• Minto property (19,864 ha).
• Broach property (19,022 ha) hosting the Tetra zone, ~13 km south of JR.
• Qualified Person: Raymond Ashley, P.Geo., President & COO of F3 Uranium, has reviewed and approved all technical information per NI 43‑101.

Notable Quotes

“We are excited to resume drilling at Tetra now that ground geophysics has been completed and plan to focus this fall drill program at a deposit scale on the Tetra zone… The unique geological setting of the Tetra zone differs from many basement‑hosted uranium deposits in the area.” – Sam Hartmann, Vice‑President, Exploration
