Greenridge completes airborne EM survey at Bradley Lake

Mr. Russell Starr reports GREENRIDGE EXPLORATION COMPLETES AIRBORNE ELECTROMAGNETIC SURVEY ON THE BRADLEY LAKE URANIUM PROJECT IN NORTHERN SASKATCHEWAN Greenridge Exploration Inc. has completed a helicopter-borne time-domain electromagnetic (HTDEM) survey on the Bradley Lake uranium project. Bradley Lake consists of a single mineral claim owned 100 per cent by Greenridge with no underlying royalties totalling 1,147 hectares and located approximately 30 kilometres northwest of Stony Rapids, Sask. The company contracted Axiom Exploration Group Ltd., of Saskatoon, Sask., Canada, to perform a high-resolution Xcite survey across the project, designed to refine conductive structural corridors on the project that could be prospective for hosting uranium mineralization. Highlights of the Bradley Lake uranium project: The project hosts the Bradley West and Bradley East uranium showings, with uranium grades in historical outcrop samples ranging up to 3.53 per cent U3O8. In 2022, ALX Resources Corp. (a company acquired by Greenridge in December, 2024) visited the Bradley Lake showings and at Bradley West mapped 60 metres of a northeast-southwest trending structure at surface, hosting multiple radioactive occurrences along its length. Four samples were collected from radioactive outcrop along the Bradley West and Bradley East showings that returned geochemical values ranging from 0.08 per cent to 1.77 per cent U3O8. Greenridge's 2025 survey represents a definitive test of the potential at the project to host deep-seated, conductive corridors that were beyond the reach of historical airborne EM methods. Russell Starr, chief executive officer of the company, stated: "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." About Bradley Lake Bradley Lake is bisected by the Grease River shear zone (GRSZ), a crustal-scale structural feature that defines the western edge of the Tantato domain in Northern Saskatchewan, and is believed to be structurally associated with the Fond du Lac uranium deposit located 34 kilometres to the southwest of the project. The project has received intermittent exploration since 1968, when radioactive occurrences were first detected in an airborne radiometric survey. In 1978, a radioactive outcrop was discovered on the project by Saskatchewan Mining and Development Corporation, a predecessor company of Cameco Corp. In 2007, a magnetic-radiometric-VLF (very-low-frequency) airborne survey was flown over Bradley Lake, which detected an approximately 700-metre-long uranium radiometric anomaly that corresponds with a portion of the known mineralized zones on surface. Two shallow scissor holes were drilled in 2011 from one collar location to undercut the presumed subsurface strike of the Bradley Lake showing at shallow depths, from which the highest-grade interval was a modest 0.047 per cent U3O8 over 0.30 metre (m) from 23.3 to 23.6 metres. The two 2011 holes, totalling only 123.4 metres, targeted the showing area and not any conductors detected by historical EM surveys, which had limited capability to detect deeper targets that may exist beneath the uranium showings on surface. Greenridge's 2025 exploration at Bradley Lake Axiom, in partnership with New Resolution Geophysics, utilized its proprietary Xcite HTDEM system, which has proven its ability to detect conductive zones up to hundreds of metres deep. Graphitic conductors are often associated with the deposition of uranium and can be readily detected by a sophisticated airborne survey such as the Xcite system. The airborne work consists of 201 line kilometres at 100-metre line spacing to provide exceptional resolution of the electromagnetic data. In addition, radiometric data were collected to detect any radioactive anomalies coincident with the surface trace of known uranium-bearing zones and which may overlap with deeper conductive anomalies. Greenridge believes that the full potential of the Bradley Lake showing has not yet been realized. The Bradley West and Bradley East showings area conveys two different styles of mineralization: pitchblende veinlets hosted by pegmatites and potentially much more significant shear-zone-hosted uranium. Both styles of mineralization display a high uranium-thorium ratio indicative of hydrothermal processes related to a structural rather than a magmatic origin (Daubeny, 2009). Greenridge plans to integrate the results of the survey with historical geological and geophysical data to better delineate the footprint of known mineralized zones at Bradley Lake. The company holds an active exploration permit for surface prospecting and sampling, and airborne and ground geophysics, valid to May 31, 2027.

Greenridge Exploration is a mineral exploration company dedicated to creating shareholder value through the acquisition, exploration and development of critical mineral projects in Canada. The company owns or has interests in 27 projects and additional claims covering approximately 334,987 hectares with considerable exposure to potential uranium, lithium, nickel, copper and gold discoveries. The company is led by an experienced management team and board of directors with significant expertise in capital raising and advancing mining projects. Greenridge has one of the largest uranium property portfolios in Canada consisting of 16 projects and additional prospective claims covering approximately 221,509 hectares. The company has opportunities to realize value in an additional 11 strategic metals projects, which include lithium, nickel, gold and copper exploration properties, totalling approximately 113,478 hectares. Project highlights include: The Black Lake property, located in the northeastern Athabasca basin (40 per cent Greenridge, 50.43 per cent Uranium Energy Corp. and 8.57 per cent Orano Canada) saw a 2004 discovery hole (BL-18) return 0.69 per cent U3O8 over 4.4 metres. The Hook-Carter property (20 per cent Greenridge and 80 per cent Denison Mines Corp.) is strategically located in the southwestern margin of the Athabasca basin, sitting approximately 13 kilometres from NexGen Energy Ltd.'s Arrow deposit and approximately 20 km from Paladin Energy's Ltd.'s Triple R deposit. The Gibbons Creek property hosts high-grade uraniferous boulders located in 2013, with grades of up to 4.28 per cent U3O8, and the McKenzie Lake project saw a 2023 prospecting program return three samples, which included 844 parts per million (ppm) uranium (U) total (0.101 per cent U3O8), 273 ppm U total and 259 ppm U total. The Nut Lake property, located in the Thelon basin, includes historical drilling, which intersected up to nine feet (ft) of 0.69 per cent U3O8, including 4.90 per cent U3O8 over one ft from an eight ft depth. In 2024, Greenridge's prospecting program located a float sample that returned 31.13 per cent U3O8, sourced from the Tundra showing.
