F3 - Starts Geophysics at Tetra Zone to Generate New Drill Targets

Executive Summary

• F3 Uranium Corp. has commenced a 30-day DIAS32 IP and resistivity geophysical survey over its 100% owned Broach Lake Property to characterize the high-grade Tetra Zone uranium discovery.
• The survey aims to generate drill targets and guide step-out drilling along the Tetra Zone system by imaging 3D chargeability and resistivity distributions, specifically designed to overcome challenging geophysical conditions.
• Upon completion, the company plans to expand survey coverage along strike and will issue a summer exploration update covering the Tetra area and additional drill-ready targets.

Key Details

• Survey Type & Location: DIAS32 IP and resistivity geophysical survey at the 100% owned Broach Lake Property, positioned directly over the Tetra Zone.
• Survey Scope: Consists of three lines designed to image chargeability and resistivity distributions in 3D.
• Duration: Approximately 30 days to complete.
• Objective: Generate drill targets along the Tetra Zone system by imaging resistivity contrast associated with the mineralized structure; guide step-out drilling along strike to expand the mineralized footprint.
• Geological Context: University of Saskatchewan drill core physical properties identified measurable resistivity contrasts through the Tetra Zone structure (showing lower resistivity than surrounding host rocks). The survey will integrate with previous ground EM survey data.
• Geophysical Challenges: The Tetra Zone lacks common conductive minerals (graphite and sulphides) and is overlain by highly conductive Cretaceous mudstone that introduces significant noise. The resistivity survey is specifically designed to overcome these challenges.
• Future Exploration Plans: Upon successful completion and interpretation, F3 intends to expand the survey coverage along strike in both directions. A summer exploration update covering the Tetra area and new target areas is expected shortly.
• Historical Context & Other Trends: Historic drill hole PAT-16-002, located 1.2 km southeast of Tetra, returned a 0.5-metre interval grading 423 ppm U. The company is focused on understanding this trend and advancing numerous other untested trends to the drill-ready stage.
• Project Overview: The Patterson Lake North Project (PLN) is a 42,961-hectare, 100% owned property located on the south-western edge of the Athabasca Basin in northern Saskatchewan. It comprises the Patterson Lake North Property (JR Zone), Minto Property, and Broach Property (Tetra Zone).

Notable Quotes

• Sam Hartmann, Vice President Exploration: "The Tetra Zone discovery has been game changing. It marked the first uranium discovery within the Clearwater Domain, a geological domain characterized by an extremely high magnetic profile and historically weak conductor responses."
• Sam Hartmann: "Many uranium discoveries in the basin are considered 'blind' and rely heavily on geophysics... The Tetra Zone is even more difficult due to the very weak geophysical property contrast associated with the mineralized structure."
• Sam Hartmann: "What we do know is that we are on a potentially large system characterized by significant hydrothermal alteration, with the Tetra Zone mineralization at its core."
