Purepoint Completes First Pass Drilling at Tabbernor Project

Rhea-AI Summary

Purepoint Uranium Group (OTCQB: PTUUF) completed its inaugural diamond drill program at the 100%-owned Tabbernor Project on November 12, 2025, completing 1,741 metres across five first-pass holes along a 60-km graphitic corridor.

All five holes intersected graphite, four of five showed structural disruption (shearing, brecciation, silicification), and assay results are pending. The project covers 51,670 hectares along the Tabbernor Fault System, ~40 km south of Eagle Point. The company will integrate drill data into regional interpretation to prioritize follow-up targets. Separately, Purepoint granted 975,000 options at C$0.52 exercisable for five years to directors and officers.

Toronto, Ontario--(Newsfile Corp. - November 12, 2025) - Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) ("Purepoint" or the "Company") today announced the completion of its inaugural drill program at the 100%-owned Tabbernor Project, located on the southeastern edge of Saskatchewan's Athabasca Basin. The program consisted of five first-pass diamond drill holes, targeting a 60-kilometre-long corridor of graphitic conductors defined through two years of detailed airborne geophysical surveys.

"This drill program provided our first look beneath surface at Tabbernor and delivered the technical insights we were aiming for," said Chris Frostad, President and CEO of Purepoint. "Every hole intersected graphite, and we encountered the types of structural, and alteration features we typically associate with uranium mineralization. That gives us a meaningful geological foundation as we begin to prioritize where and how to drill next."

Highlights

• 1,741 metres of diamond drilling completed across five holes.
• All five holes intersected graphite, validating our recent airborne electromagnetic (EM) signatures.
• Four of five holes intersected zones of structural disruption:
  • Shearing observed in TB25-02, TB25-03, SMP25-01 and SMP25-02.
  • Brecciation recorded in TB25-02, TB25-03 and SMP25-02.
• Silicification identified in TB25-01, TB25-02 and SMP25-02.
• Assay results for all holes are pending.

The five drill targets were distributed across the broader Tabbernor conductive corridor and designed to provide a representative geological cross-section of the system's various structural domains. The drill results will allow Purepoint to further refine its understanding of the underlying geology, confirm the location and character of graphitic horizons, and evaluate zones of structural complexity for follow-up.

The Tabbernor Project spans more than 50,000 hectares and is positioned along the northern extension of the Tabbernor Fault System-a major crustal structure that aligns with numerous uranium occurrences throughout the Basin. Despite this regional potential, the area has seen little to no systematic drill testing for uranium until now.

Purepoint intends to incorporate the results of the current drill program into its ongoing regional interpretation work, with the goal of prioritizing follow-up targets for more detailed evaluation.

Tabbernor Project

The 100%-owned Tabbernor Project is strategically positioned along three major trends of the Tabbernor Fault System, a deep seated, 1,500-kilometre crustal shear system that runs north through the Athabasca Basin. The system not only hosts over 80 historic mines and gold occurrences but also crosscuts the Basin's mine trend aligning itself with 8 of the Basin's largest uranium discoveries.

The Tabbernor project is roughly 40 kilometres south of Cameco's Eagle Point deposit and is comprised of 23 contiguous mineral claims covering an area of 51,670 hectares. The original three north-south claim groups that covered Tabbernor structures have now been expanded to include a strong east-northeast trending corridor of conductive rocks further enhancing the project's exploration potential.

Purepoint's current focus is the 60-kilometre graphitic corridor that cuts through the project, specifically, areas with gravity low responses and showing evidence of structural complexity. Notably, recent drilling on an adjacent property intersected significant mineralization associated with the central Tabbernor graphitic structure (see CanAlaska Uranium Ltd. press release, September 27, 2023).

Tabbernor Fault System

The Tabbernor Fault System (TFS) is a wide, >1,500 kilometre geophysical, topographic, and geological structural zone that trends approximately northward along Saskatchewan's eastern boundary. Purepoint's research has shown that although none of the province's currently known uranium deposits have been linked to the north-south trending TFS, localized shear zones hosting uranium mineralization may have an associated north-south structural component.

Reactivation of the TFS may have coincided with the age of formation of large uranium deposits in the Athabasca Basin (Davies, 1998). Davies also concluded that structural similarities between the TFS and mineralized areas suggest that the fault system may have had a control on the location of mineralization. More specifically, he considered that several deposits, such as the Sue, Midwest, Dawn Lake and Rabbit Lake all demonstrate a north-south control and strong Tabbernor-like characteristics.

Grant of Options

The Company also announced it approved the issuance of a total of 975,000 options (the "Options") to its directors and officers pursuant to the Company's Omnibus Equity Incentive Compensation Plan. The Options are exercisable at a price of $0.52 per common share and expire on the date that is five years from the date of grant.
