F3 Uranium starts 3,000 m drill program at Broach Lake

Executive Summary

• F3 Uranium Corp. has commenced a 3,000-metre winter diamond drill program at its 100%-owned Broach Lake property, specifically targeting the high-grade Tetra zone discovery within the Patterson Lake North project.
• The program aims to test the extent of uranium mineralization, focusing on down-dip and down-plunge stepouts to the west, followed by testing the up-plunge extension where approximately 300 metres of undrilled prospective shear zone remains toward the Athabasca unconformity.
• This follows recent fall program results that extended the interpreted mineralized plunge length from 60 metres to 135 metres, with key intercepts including PLN25-205 (1.0m at 2.50% U3O8) and PLN25-219A (29.5m total mineralization, including 2.30m >10,000 cps).

Key Details

• Drill Program Scope: 3,000 metres of diamond drilling.
• Target Area: Tetra zone, Broach Lake property, Patterson Lake North (PLN) project, southwestern edge of the Athabasca basin, Saskatchewan.
• Strategic Focus:
  • Initial phase: Down-dip and down-plunge stepouts to the west (addressing two westernmost holes from the fall program that overshot the target).
  • Secondary phase: Testing the up-plunge extension toward the Athabasca unconformity, where ~300 metres of undrilled prospective shear zone exists.
• Previous Context (Fall Program):
  • Extended interpreted mineralized plunge length from 60 metres to 135 metres.
  • Key Intercept PLN25-205: 1.0 metre of 2.50% U3O8 within a broader 22.5-metre interval averaging 0.26% U3O8.
  • Key Intercept PLN25-219A: 29.5 metres of total mineralization, including 27.5 metres continuous, with 2.30 metres exceeding 10,000 counts per second (cps).
• Geological Context: The unconformity area shows highly prospective geology and pathfinder element geochemistry.
• Grade Definitions:
  • High Grade: >1.0 wt% U3O8.
  • Ultrahigh Grade: >20.0 wt% U3O8.
• Measurement Methodology: Natural gamma radiation measured in counts per second (cps) using a handheld Radiation Solutions RS-125 spectrometer.
  • Anomalous: >300 cps.
  • Highly Radioactive: >10,000 cps.
  • Off Scale: >65,535 cps.
  • Note: Spectrometer readings are preliminary indicators and do not directly correlate with assay grades.
• Project Location: 12 km northwest of Paladin's Triple R and 16 km west-northwest of NexGen Energy's Arrow deposits.

Notable Quotes

• Sam Hartmann, Vice-President of Exploration: "We are very excited to resume drilling at Tetra zone with an ambitious winter program ahead. Mineralization remains open both down plunge to the west at depth and up plunge to the east toward the Athabasca unconformity, with roughly 300 metres of prospective untested shear in the up-plunge direction. We also await all outstanding assays from the fall program, including from hole PLN25-219A, which delivered our strongest radioactivity to date with 2.30 metres greater than 10,000 cps within 27.5 metres of continuous mineralization."
