Greenridge completes airborne EM survey at Bradley Lake

Executive Summary

• Greenridge Exploration Inc. has completed a high-resolution helicopter-borne time-domain electromagnetic (HTDEM) survey on its 100% owned Bradley Lake uranium project in Northern Saskatchewan.
• The survey, conducted by Axiom Exploration Group Ltd., covered 201 line kilometres with 100-metre line spacing to identify deep-seated conductive corridors potentially hosting uranium mineralization, which were beyond the reach of historical exploration methods.
• The project hosts historical uranium showings with grades up to 3.53% U3O8 and is located near the Grease River shear zone, structurally associated with the nearby Fond du Lac uranium deposit.

Key Details

• Survey Specifications:
  • Conducted by Axiom Exploration Group Ltd. (Saskatoon, Sask.) using a proprietary Xcite HTDEM system in partnership with New Resolution Geophysics.
  • Coverage: 201 line kilometres at 100-metre line spacing.
  • Objective: Refine conductive structural corridors prospective for uranium mineralization and detect deep-seated conductive zones (graphitic conductors often associated with uranium deposition).
  • Additional Data: Radiometric data collected to detect radioactive anomalies coincident with surface traces of known zones.
• Project Location and Tenure:
  • Bradley Lake uranium project, Northern Saskatchewan.
  • Located approximately 30 km northwest of Stony Rapids, Sask.
  • Single mineral claim, 100% owned by Greenridge, no underlying royalties.
  • Total area: 1,147 hectares.
• Historical Context and Mineralization:
  • Hosts Bradley West and Bradley East uranium showings.
  • Historical outcrop samples returned grades up to 3.53% U3O8.
  • In 2022, ALX Resources (acquired by Greenridge in Dec 2024) mapped 60m of a NE-SW trending structure at Bradley West with multiple radioactive occurrences.
  • Four samples from 2022 returned geochemical values ranging from 0.08% to 1.77% U3O8.
  • Project is bisected by the Grease River shear zone (GRSZ), a crustal-scale feature defining the western edge of the Tantato domain.
  • Structurally associated with the Fond du Lac uranium deposit (34 km SW).
  • First radioactive occurrences detected in 1968; outcrop discovered in 1978 by Saskatchewan Mining and Development Corp. (predecessor to Cameco).
  • 2007 magnetic-radiometric-VLF survey detected a ~700m long uranium radiometric anomaly corresponding to surface mineralized zones.
  • 2011 drilling (123.4m total in two shallow scissor holes) intersected a modest interval of 0.047% U3O8 over 0.30m from 23.3 to 23.6m.
• Future Plans:
  • Greenridge plans to integrate 2025 survey results with historical geological and geophysical data to delineate the footprint of known mineralized zones.
  • Active exploration permit for surface prospecting, sampling, and airborne/ground geophysics valid until May 31, 2027.
  • Management believes the full potential has not been realized, noting two styles of mineralization: pitchblende veinlets in pegmatites and potentially more significant shear-zone-hosted uranium.

Notable Quotes

• "Bradley Lake is yet another promising uranium project in the Greenridge property portfolio that received little of the follow-up exploration that was recommended by previous explorers. We are pleased to carry out a high-resolution HTDEM survey at Bradley Lake and will integrate the 2025 results with our historical database to search for the potential sources of the high-grade uranium showings that are present on surface at the project." — Russell Starr, Chief Executive Officer
