Greenridge Exploration Identifies Uranium Targets from Airborne Electromagnetic Survey at the McKenzie Lake Uranium Project in Northern Saskatchewan

Executive Summary

• Greenridge received interpretation of a 365 km HTDEM survey over the McKenzie Lake Uranium Project, identifying a major north‑south fault zone and discrete conductive anomalies that may indicate prospective uranium mineralization.
• The high‑resolution EM and magnetic data improve structural understanding and will guide surface exploration and drill targeting in 2026.
• Historical prospecting on the project has already returned uranium‑bearing boulders up to 0.101% U₃O₈, supporting the potential significance of the newly identified anomalies.

Key Details

• Survey Scope: 365 line‑kilometres flown at 200 m line spacing using Axiom’s proprietary Xcite™ HTDEM system – first deep‑penetrating EM survey of McKenzie Lake in the modern uranium exploration era.
• Key Findings:
• Mapped a major north‑south fault bisecting the project area.
• Identified discrete conductive zones along and peripheral to this fault (see Figure 2).
• Early‑time EM response shows conductivity trend overlapping a magnetic low and the regional fault, suggesting graphitic or sulfide bodies typical of uranium‑bearing settings in the Athabasca Basin.
• Magnetic Data: Provided high‑resolution mapping of geological domains and fault structures that could host uranium mineralization.
• Integration Plan: 2025 EM results will be combined with 2021 high‑resolution magnetic and radiometric surveys to plan 2026 surface exploration, including prospecting and ground geophysical work recommended by Convolutions Geoscience Inc.
• Historical Context: Prior prospecting in 2021 discovered a large angular boulder grading up to 0.101% U₃O₈; additional radioactive boulders and soil anomalies have been found, indicating possible “up‑ice” uranium sources.
• Exploration Permit: Active airborne/ground geophysics and surface prospecting permit valid through 31 Mar 2027.
• Management Quote (Russell Starr, CEO): Emphasized that the new EM data, when layered with existing magnetic and radiometric results, will greatly assist future exploration efforts at McKenzie Lake.

Notable Quotes

“The results we have obtained this year from the McKenzie Lake airborne survey are yet another example of finding new target areas from the use of modern exploration tools. Layering the new EM data with other recent prospecting and radiometric results will greatly assist our future exploration efforts at the Project.” – Russell Starr, Chief Executive Officer
