Greenridge Exploration Launches Geophysical Data Review Program for the Sabre Uranium Project in Northern Saskatchewan

Rhea-AI Summary

Greenridge Exploration (GXPLF) has engaged Convolutions Geoscience to conduct a comprehensive geophysical and geological data review for its Sabre Uranium Project in Saskatchewan's Athabasca Basin. The review aims to create a 3D subsurface model to identify potential uranium deposits and develop new drill targets. Convolutions will integrate data from multiple historical surveys conducted between 2005-2023, including recent MobileMT airborne survey results from April 2025. The company will utilize data from CMIC's Footprints Basinal U Subproject and Saskatchewan's Athabasca Basin 3D Model 2.0. The Project is permitted for surface exploration until November 2027, including authorization for up to 10 drill holes. The data review is expected to be completed in Q2 2025.

VANCOUVER, British Columbia, June 10, 2025 (GLOBE NEWSWIRE) -- Greenridge Exploration Inc. (“Greenridge” or the “Company”) (CSE: GXP | FRA: HW3 | OTCQB: GXPLF), is pleased to announce it has engaged Convolutions Geoscience of Surrey, BC, Canada (“Convolutions”), to perform a comprehensive review and integration of all available geophysical and geological data for the Sabre Uranium Project (the “Sabre Property”, or the “Project”) located in the northern Athabasca Basin of Saskatchewan, Canada. The purpose of the data review is to produce a comprehensive 3D model of the subsurface to detect the presence of potential uranium-mineralizing system and develop new drill targets for the Project.

Convolutions is composed of a team of geophysical experts with a depth of experience in exploration for uranium in the Athabasca Basin, which hosts the richest uranium deposits in the world. Athabasca Basin uranium deposits are volumetrically small, i.e., individual high-grade zones within mineralized trends typically being tens to a few hundred metres long and a few tens of metres wide and thick, creating a challenge for uranium explorationists. Greenridge believes that Convolutions’ interpretive methods will contribute to a focussed discovery path to the different types of uranium deposits now being recognized in the Athabasca Basin after over sixty (60) years of exploration.

Russell Starr, CEO of Greenridge, commented, “Convolutions will provide key insights that will allow Greenridge to advance the Sabre Property towards a drilling program. The 3D model will provide high priority drill targets and an in-depth model which can be used as the Project moves forward.”

In conjunction with re-processing historical geophysical data from the Sabre Property, Convolutions will utilize the geophysical and petrophysical data collected by the Canadian Mining Innovations Council’s (“CMIC”) Footprints Basinal U Subproject¹ and the Athabasca Basin 3D Model 2.0 developed by the Government of Saskatchewan² with the goal of enhanced targeting for uranium.

In April 2025, Greenridge completed a deep-penetrating MobileMT airborne survey at the Sabre Property (please see the Company’s News Release dated April 30, 2025) and will integrate the 2025 airborne results with data from the following historical geophysical surveys:

• 2005 MEGATEM Airborne
• 2005 Falcon Airborne Gravity
• 2006 Ground Horizontal Loop Electromagnetic
• 2007 VTEM Airborne
• 2007 Ground DC/Resistivity
• 2007 Ground Time Domain Electromagnetic
• 2023 Ground Time Domain Electromagnetic
  

Greenridge believes that the results of Convolution’s data review and inversions will provide new uranium targets on the Sabre Property. The Project is fully permitted for surface exploration until November 30, 2027, which includes drilling of up to 10 holes. The data review is expected to be completed in Q2 of 2025.

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.³
