Greenridge survey outlines uranium targets at Sabre

Mr. Russell Starr reports GREENRIDGE EXPLORATION RECEIVES AIRBORNE MOBILEMT SURVEY RESULTS FOR THE SABRE URANIUM PROJECT IN ATHABASCA BASIN, SASKATCHEWAN Greenridge Exploration Inc. has released the results of a high-resolution helicopter-borne mobile magnetotellurics (MobileMT) survey at the Sabre uranium project located in the northern Athabasca basin region of Saskatchewan, Canada. Highlights of the survey at Sabre The survey successfully identified robust basement conductors at depths of approximately 300 to 400 metres, exhibiting the characteristic response of graphite-rich lithologies. These graphitic conductors may indicate key structural and chemical traps for uranium deposition within the Athabasca basin. Alongside the basement conductor responses, the system identified areas of secondary conductivity at shallower depths within the overlying Athabasca sandstone sequence. These anomalies may indicate clay alteration halos, which typically form near hydrothermal fluid flow related to unconformity-type uranium mineralizing systems. The MobileMT data confirm several structural corridors trending from northeast to southwest, as well as cross-cutting features, some of which are spatially associated with uraniferous sandstone boulders found at surface. These structures could potentially serve as fluid pathways or structural controls influencing mineralization. The origin of the boulders is still unknown, making these features a high-priority target for further exploration. Russell Starr, chief executive officer of the company, stated: "Greenridge is very pleased to receive these geophysical results for Sabre, which confirms the company's belief that the project is highly prospective for unconformity-type uranium deposits at a time when uranium has become a critical commodity. Greenridge is one step closer to drill testing Sabre in the months to come." About the survey Expert Geophysics Ltd. (EGL) carried out the survey, which totalled 1,536 line kilometres flown at 200-metre-line spacing over a 232-square-kilometre area. Processing of the airborne data collected were performed by Convolutions Geoscience using the most advanced digital processing tools currently available. EGL introduced its MMT system in 2018 as a next-generation platform for airborne natural source audio-frequency magnetotellurics (AFMAG). The method utilizes naturally occurring electromagnetic energy generated by global lightning activity, which propagates through the atmosphere as low-frequency plane waves and couples into the subsurface. These natural fields induce secondary electromagnetic responses within the earth, which are measured by the MMT system. By analyzing variations in the amplitude and phase of the received AFMAG fields, MMT provides high-resolution mapping of subsurface electrical resistivity contrasts. The system is capable of investigating to depths exceeding approximately one kilometre, making it particularly well suited for exploration in regions such as the Athabasca basin, where the depth to the unconformity between the Athabasca Supergroup sandstones and the underlying basement rocks can vary from surface exposure to several hundred metres over relatively short lateral distances. About Sabre Sabre is located on the northern edge of the Athabasca basin approximately 30 kilometres west of Stony Rapids and 10 kilometres south of Fond du Lac, Sask. The project consists of 28 mineral claims totalling 23,178 hectares and is prospective for hosting unconformity-related uranium mineralization. The Fond du Lac uranium deposit, a shallow, sandstone-hosted deposit, is located approximately 5.5 kilometres to the northwest of the project's western boundary, which may demonstrate the prospectivity of the region for the deposition of uranium mineralization. Historical exploration at the project has identified anomalous uranium-bearing sandstone boulders and outcrop at surface, numerous interpreted fault structures and EM conductors interpreted to lie at depths greater than 300 metres. Drill testing for uranium within the current boundaries of the project is limited to five historical drill holes. Hole MNL-02, drilled by UEX Corp. in 2006, intersected highly anomalous dravite veining (a boron-rich clay mineral) in the sandstone at a depth of 290.5 metres, which is a clay alteration mineral commonly associated with uranium deposition in the Athabasca basin. Moving loop time domain EM ground surveys are recommended for the winter of 2025 to 2026 to provide greater detail of the airborne conductors for future drill testing. Sabre is fully permitted for uranium exploration, including prospecting, geophysical surveys and drilling until Nov. 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.

Mr. Hillacre has examined information regarding the historical exploration at the project, which includes a review of the historical sampling, analytical and procedures underlying the information and opinions contained herein. Management cautions that historical results collected and reported by operators unrelated to Greenridge have not been verified nor confirmed by its qualified person; however, the historical results create a scientific basis for continuing work in the project. Management further cautions that historical results, discoveries and published resource estimates on adjacent or nearby mineral properties, or other properties located within the Athabasca basin, whether in stated current resource estimates or historical resource estimates, are not necessarily indicative of the results that may be achieved on the project. The QP has been unable to verify the information pertaining to the Fond du Lac uranium deposit, and the deposit is not necessarily indicative to the mineralization on the property that is the subject of this disclosure.
