Purepoint Commences Summer Drill Program at Dorado, Targeting Expansion of the High-Grade Nova Uranium Discovery

Executive Summary

• Purepoint Uranium Group Inc. has commenced its fully funded summer 2026 drilling program at the Dorado Project, a 50/50 joint venture with IsoEnergy Ltd. in Saskatchewan's Athabasca Basin.
• The program targets expansion of the high-grade Nova Discovery and evaluation of additional high-priority regional conductive targets across the broader project.
• Seven drill holes totaling approximately 3,150 metres are planned through July and August 2026, building on a successful winter campaign that defined a one-kilometre structural corridor with assays up to 8.1% U3O8.

Key Details

• Drilling Commencement: Summer 2026 program officially started at the Dorado Project.
• Program Scope: 7 drill holes planned, totaling approximately 3,150 metres.
• Timeline: Drilling expected to continue through July and August 2026.
• Primary Objective: Expand the high-grade Nova Discovery; test the interpreted plunge of the mineralized structure; evaluate its projected extension toward the unconformity.
• Secondary Objective: Evaluate several high-priority conductive targets identified by previous geophysical surveys that have not yet been drill tested.
• Winter Program Results: 9-hole campaign successfully traced uranium mineralization across a one-kilometre structural corridor; all holes intersected radioactivity >500 cps; peak downhole gamma reading of 73,100 CPS recorded; assays remain pending.
• Historical Assays: Nova Discovery has returned confirmed assays up to 8.1% U3O8.
• Geophysical Surveys: Airborne MobileMT survey recently completed over the Dorado Project; results will be integrated into ongoing geological interpretation and future drill targeting.
• Logistics: Helicopter-supported drilling with accommodations and fuel logistics provided through Points North Landing.
• Project Context: Dorado Project encompasses >98,000 hectares in the eastern Athabasca Basin; shallow unconformity depths allow for efficient drilling and rapid follow-up.

Notable Quotes

• Chris Frostad, President and CEO: "The winter program significantly improved our understanding of the Nova system. We now have a much stronger geological model that is directing this next phase of drilling. Our objective this summer is to test the interpreted plunge of the mineralized structure, evaluate its potential extension toward the unconformity, and continue assessing additional high-priority targets across the broader Dorado Project. Each drill program is building on the success of the last and moving us systematically toward defining the full scale of the system."
