Greenridge Exploration Completes Airborne MobileMT Survey at the Sabre Uranium Project in Athabasca Basin, Saskatchewan

Rhea-AI Summary

Greenridge Exploration has completed a major geophysical survey at its Sabre Uranium Project in Saskatchewan's Athabasca Basin. The helicopter-borne MobileMT survey covered 1,536 line-kilometres at 200-metre spacing across 232 square kilometres.

The survey aims to map underground magnetic signatures and detect conductive zones that could host uranium deposits. To strengthen exploration efforts, Greenridge plans to compile historical geophysical data, including surveys from 2005-2023 conducted by various companies.

The Sabre Property maintains uranium exploration permits valid until November 30, 2027, covering activities like prospecting, geophysical surveys, and drilling. The company is actively engaging with local Northern Athabasca communities to build beneficial relationships.

VANCOUVER, British Columbia, April 30, 2025 (GLOBE NEWSWIRE) -- Greenridge Exploration Inc. (“Greenridge” or the “Company”) (CSE: GXP | FRA: HW3 | OTCQB: GXPLF) is pleased to announce the completion of a high-resolution helicopter-borne Mobile MagnetoTellurics System (“MobileMT”) survey at the Sabre Uranium Project (the “Sabre Property” or the “Project”) located in the northern Athabasca Basin region of Saskatchewan, Canada.

The Project-wide MobileMT survey completed by Expert Geophysics Surveys Inc. (“EGS”) consisted of 1,536 line-kilometres flown at 200-metre line spacings over a 232 square kilometre area. The MobileMT survey was implemented to map sub-surface magnetic signatures and detect conductive zones within the margin of the Athabasca Basin sandstones that may be prospective for hosting unconformity-related uranium mineralization.

The Company believes that its use of the MobileMT system is ideal for the advancement of exploration at the Sabre Property through delineation of major conductive structural systems, and the Company looks forward to the interpretation of the 2025 results to develop new drill targets. In conjunction with the processing and interpretation of the 2025 MobileMT data, Greenridge plans to undertake an extensive geophysical data compilation, which would include the following historical datasets:

• 2005 Falcon airborne gravity survey (UEX Corporation);
• 2005 MegaTEM airborne electromagnetic survey (UEX Corporation and RPT Uranium Corp.);
• 2007 DC Resistivity survey (UEX Corporation);
• 2007 TDEM survey (UEX Corporation); and
• 2023 Fixed Loop Time Domain electromagnetic survey (ALX Resources Corp.).
  

The Sabre Property is fully-permitted for uranium exploration, including prospecting, geophysical surveys and drilling, until November 30, 2027. Engagement with local communities is ongoing with the goal of creating a mutually beneficial relationship between the Company and the residents of the Northern Athabasca region.

About the Sabre Property

The Sabre Property is located on the northern edge of the Athabasca Basin approximately thirty (30) kilometres west of Stony Rapids and ten (10) kilometres south of Fond du Lac, Saskatchewan. The Project is comprised of twenty-eight (28) claims totaling 23,178 hectares and is believed to be prospective for hosting unconformity-related uranium mineralization. The Fond du Lac uranium deposit, a shallow, sandstone-hosted deposit with a historic reserve of approximately 990,000 pounds (450,000 kilograms) averaging 0.25% U₃O₈ is located approximately 5.5 kilometres to the northwest of the Project’s western boundary (please see Figure 1), which may demonstrate the prospectivity of the region for the deposition of uranium mineralization.¹

Historical exploration at the Sabre Property has identified anomalous uranium-bearing sandstone boulders and outcrop at surface, numerous interpreted fault structures, and electromagnetic (“EM”) conductors interpreted to lie at depths greater than three hundred (300) metres. Graphitic conductors can provide favourable conduits and host environments for the deposition of uranium at or near the unconformity between the Athabasca sandstones and the older Archean and Paleoproterozoic basement rocks.

Drill testing for uranium within the current boundaries of the Sabre Property is limited to five (5) historical drill holes. Hole MNL-02, drilled by UEX Corporation in 2006, intersected anomalous dravite veining that returned a geochemical value of 2,059 parts per million boron in the sandstone at a depth of 290.5 metres, approximately 23 metres above the unconformity, which was reached at 322.4 metres.² Dravite is recognized as a pathfinder clay alteration mineral that is often associated with uranium mineralization in the Athabasca Basin.
