On October 25, 2022 Greenridge announced the completion of a prospecting program at Sabre. Two radioactive zones were located on surface in the Athabasca sandstone by Greenridge’s prospecting team adjacent to an interpreted structural zone of quartz vein brecciation.

• A significant trend of structural disruption in the Athabasca sandstone known as the Jigsaw Zone was discovered. The structure is exposed at surface as quartz veining and local quartz-breccia in abundant angular boulders (i.e., not far-traveled by glacial movement), sub-crop and outcrop of sandstone and can be traced over a trend approximately 150 metres long by 15 metres wide. The Jigsaw Zone is open along strike to northeast and southwest and disappears under cover in both directions.
• A trend of elevated radioactivity in boulders in possible outcrop or subcrop was located 15 metres to the south of Jigsaw Zone and is presumed to be a historical uranium-phosphate showing first reported in 1979. Two small pits (“West” and “East”) were hand dug by Greenridge to better expose the radioactive sources.  Scintillometer readings of up to 550 counts per second (“cps”) and 250 cps were obtained from inside the bottom of the West and East pits, respectively (10 to 20 times background radiation levels).
