North Shore Uranium Ltd. Completes Prospecting Program at Falcon; Significant Radioactivity Discovered in Outcrops and Boulders

VANCOUVER, BC / ACCESS Newswire / October 14, 2025 / North Shore Uranium Ltd. (TSXV:NSU) ("North Shore" or the "Company") is pleased to announce the completion of a prospecting program on its Falcon Property ("Falcon" or the "Property") located at the eastern margin of the Athabasca Basin in Saskatchewan.

The prospecting program was completed by Axiom Exploration Group and focused on eighteen priority targets that were identified by North Shore's technical team. At each of these targets, the crew assessed the mapped surface expression of the interpreted electromagnetic ("EM") conductor and surrounding area for outcrop and anomalous radioactivity. A Radiation Solutions (model RS-125) scintillometer that measures total radioactivity in counts per second ("cps") was used to measure the radioactivity of outcrops and boulders and guide the selection of representative rock samples for laboratory analysis.

Significant radioactivity was confirmed in outcrop at targets FA020, up to 20,000 cps (the historic EWA Showing) and FA025, up to 27,000 cps (the historic D Zone Showing area) (Figure 1). In addition, several boulders with elevated radioactivity were discovered, including at targets FA019, close to 7,000 cps and FA033, up to 6,000 cps. Summaries of work done at several targets are presented below. Seventy-four rock samples were collected during the program and they have been submitted to the Saskatchewan Research Council (SRC) Geoanalytical Laboratory for uranium, associated metals and elements and Rare Earth Element analysis. Assay results are pending.

Brooke Clements, President and CEO of North Shore stated: "We think that Falcon has all the right ingredients to yield a signficant new uranium discovery. It is in the Athabasca Basin region, host to Canada's only two uranium mines and three development-stage projects. Uranium mineralization has been confirmed on the property, and the past-producing Key Lake Uranium Mine and active Key Lake Mill is nearby. We have identified a number of high priority, drill-ready targets along portions of a prominent EM conductor system that have seen no historic drilling."

PRIORITY TARGETS BY ZONE

Three priority areas have been established at Falcon, Zones 1, 2 and 3. Within these three areas, 36 uranium targets have been identified (Figure 1). The targets are associated with EM conductor anomalies and have been selected based on the analysis and interpretation of multiple geophysical and geologic datasets.
