Greenridge Exploration Inc. announced its exploration plans for a helicopter-borne time domain electromagnetic survey and follow-up prospecting and mapping at the Blackbird Project located in northern Saskatchewan, Canada. The Blackbird Property is situated in an underexplored area of Saskatchewan that has recently gained recognition following new discoveries of gold and critical metals mineralization in drilling programs. The Blackbird Property lies approximately 70 kilometres (47 miles) north of LaRonge, Saskatchewan in a newly-emerging metallogenic district south of the historic Rottenstone Mine, which produced nickel, copper, gold and platinum group metals from 1965 to 1969. In June 2024, Ramp Metals Inc. reported a high-grade gold discovery at their Rottenstone SW project in drill hole Ranger-1, which intersected 73.55 grams/tonne gold over 7.5 metres from 227.0 to 234.5 metres.2 In late April 2025, Ramp Metals reported initial results of additional drilling at the Rottenstone SW project, including details of a series of intersections of massive sulphides at the Rush target with copper and zinc mineralization identified by a hand-held XRF analyzer.

No significant radioactive anomalies were detected within the 1968 survey area over what is now the southern claim block of Blackbird and as a result, the Project area did not receive any ground follow-up exploration. In 1974, the Geological Survey of Canada ("GSC") carried out a regional lake sediment geochemical survey over an approximate 51,000 square kilometre area, which included the Project area. Management further cautions that historical results, discoveries and published resource estimates on adjacent or nearby mineral properties, or other properties located within northern Saskatchewan, whether in stated current resource estimates or historical resource estimates, are not necessarily indicative of the results that may be achieved on the Blackbird Property.

The Gibbons Creek property hosts high-grade uraniferous boulders located in 2013, with grades of up to 4.28% U3O82, and the McKenzie Lake project saw a 2023 prospecting program return three samples which included 844 ppm U-total (0.101% 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 9ft of 0.69% U3O8 including 4.90% U3O8 over 1ft from 8ft depth. In 2024, Greenridge's prospecting program located a float sample that returned 31.13% U3O8, sourced from the Tundra Showing.

The Firebird Nickel property has seen two drill programs (7 holes totaling 1,339 m), where hole FN20-002 intersected 23.8 m of 0.36% Ni and 0.09% Cu, including 10.6 m of 0.55% Ni and 0.14% Cu. The Electra Nickel project 2022 drill program included results of 2,040 ppm Ni over 1m and 1,260 ppm Ni over 3.5m. The Company has strategic partnerships which includes properties being operated and advanced by Denison Mines Corp.
