Vancouver, BC – September 18, 2026 -- Purecore Metals Inc. (CSE: PURE) (FSE: J8Y) (OTCQB: PPURF) has commenced a comprehensive data compilation and technical review program at the Yurchison Uranium Property in the Athabasca Basin, northern Saskatchewan, a 35,029-hectare asset located approximately 75 kilometres south of Cameco Corporation's Rabbit Lake operation.
Purecore holds an option to earn up to 100% of the Skyharbour-optioned property
The Company holds an option to earn up to a 100% interest in Yurchison under a definitive agreement with Skyharbour Resources Ltd. (TSXV: SYH). The property comprises 22 claims and sits within the Wollaston Domain, underlain by Wollaston Supergroup metasedimentary gneisses adjacent to Archean granitic gneisses.
Historical trenching returned uranium grades of 0.09% to 0.30% U3O8
Prospecting near historical trenches on the property identified uranium mineralization ranging from 0.09% to 0.30% U3O8. Much of the earlier exploration predates 2000, while additional modern airborne geophysical surveys have been completed in recent years, including a 1,424 line-kilometre high-resolution airborne magnetic survey flown at 50-metre line spacing and earlier VTEM work that identified multiple geophysical zones of interest.
The program will integrate decades of geophysical and geochemical datasets into a single framework
The current review will compile and digitize historical geological, geochemical, geophysical and drilling data, integrate historical and modern airborne geophysical datasets, and assess structural controls relevant to uranium mineralization. The Company will compare geophysical conductors, structural features and geochemical anomalies to rank priority areas for potential follow-up exploration.
Peter Berdusco, President and CEO of Purecore, said the property carries decades of exploration history and a significant volume of modern geophysical data that the program aims to consolidate into an integrated geological framework to prioritize future exploration areas.
Highway 905 provides direct access through the property area. Dr. Dennis LaPoint, P.Geo., an independent Qualified Person under National Instrument 43-101, reviewed and approved the technical information in the disclosure.
