F4 and UraniumX Hit Anomalous Radioactivity in 300 m Step Out Holes

Executive Summary

• F4 Uranium Corp announced preliminary drill results from holes ML26-017 and ML26-018 at its Murphy Lake property in the Athabasca Basin, both intersecting anomalous radioactivity and a significant graphitic/sulphide-rich deformation zone over 300m along strike from previous drilling.
• The company plans to advance its ~2,500m drill program to Target Area 4 to test the northern extension of the mineralized conductor system identified by recent Moving Loop Electromagnetic (MLEM) surveys.
• Drilling is fully funded by UraniumX Discovery Corp. under an option agreement allowing UraniumX to earn up to a 70% interest in the property.

Key Details

• ML26-017: Intersected 0.5 m of anomalous radioactivity up to 460 cps above a ~13 m wide graphitic and sulphide-rich deformation zone in basement rocks. Handheld scintillometer readings >300 cps over 0.5 m (386.0–386.5 m), peaking at 460 cps. Downhole gamma readings >500 cps over 0.4 m (385.2–385.6 m), peaking at 2,217 cps.
• ML26-018: Intersected the same deformation zone and anomalous radioactivity up to 350 cps up-dip of ML26-017. Handheld scintillometer readings >300 cps over 0.5 m (347.0–347.5 m), peaking at 350 cps. Downhole gamma readings >500 cps over 6.6 m (343.4–350.0 m), peaking at 1,097.5 cps.
• Deformation Zone: A ~13.2 m zone (401.6–414.8 m) intersected in ML26-017 and a 10.3 m zone (355.8–366.1 m) in ML26-018, featuring strong graphite, sulphide presence, and intermittent silica alteration. Matches the conductive trend imaged by MLEM surveys.
• Alteration: Intense hydrothermal alteration observed in the Athabasca Sandstone, including strong bleaching, clay alteration immediately above the unconformity, and patchy limonite alteration.
• Program Status: Approximately 2,500 m program with four holes completed to date in Target Areas 1 and 2, following up on historic hole ML22-012 which intersected 56 ppm U in sandstone above the unconformity.
• Funding & Option: F4 is the operator, with the program fully funded by UraniumX Discovery Corp. pursuant to an option agreement allowing UraniumX to earn up to a 70% interest.
• Future Drilling: Program will advance to Target Area 4 to test the northern extension of the mineralized conductor system, targeting a conductor identified by the recent MLEM survey. Target Area 2 remains a priority for follow-up at the unconformity and along strike.
• Technical Notes: Radiometric readings are preliminary and not directly correlated to uranium grades. Samples are split at 0.5 m intervals and sent to SRC Geoanalytical Laboratories for a 63-element suite including U by ICP-MS. Uranium mineralization >1.0% U₃O₈ is classified as high grade, and >20.0% U₃O₈ as ultra-high grade. All depths are downhole; true thicknesses are pending.

Notable Quotes

• Erik Sehn, P.Geo, VP Exploration: "Building on the visual identified pitchblende in the first hole of the program, the results from holes ML26-017 and ML26-018 are equally encouraging, displaying anomalous radioactivity alongside a substantial graphitic and sulphide-rich structural zone located more than 300 metres along strike from our earlier holes... Intersecting these same key ingredients-structure, alteration, and radioactivity-over such a distance, strengthens our interpretation of a robust, fertile system at Murphy Lake."
