PUREPOINT COMMENCES SUMMER DRILL PROGRAM AT DORADO, TARGETING EXPANSION OF THE HIGH-GRADE NOVA URANIUM DISCOVERY

Drilling has commenced at the Dorado project, the flagship asset of Purepoint Uranium Group Inc.'s 50/50 joint venture with IsoEnergy Ltd., located in Saskatchewan's Athabasca basin. The fully financed summer 2026 program is designed to build on the high-grade Nova discovery, where winter drilling successfully expanded uranium mineralization across a one-kilometre structural corridor and refined the geological model for continued exploration. Seven drill holes totalling approximately 3,150 metres are planned through July and August, 2026, with the program focused on expanding the Nova discovery while also evaluating additional high-priority regional targets across the broader Dorado project.

"The winter program significantly improved our understanding of the Nova system," said Chris Frostad, president and chief executive officer of Purepoint. "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."

Highlights:

• Summer drilling is targeting expansion of the high-grade Nova discovery, where previous drilling returned assays of up to 8.1 per cent U3O8 (triuranium octoxide) and defined a one-kilometre structural corridor hosting radioactivity that remains open along strike, at depth and toward the unconformity.
• Seven holes totalling approximately 3,150 metres are planned; drilling is expected to continue through July and August, 2026.
• The program follows a successful nine-hole winter campaign at the Nova discovery that intersected radioactivity greater than 500 counts per second in all holes and refined the geological model for continued exploration.
• Winter drilling confirmed a peak downhole gamma reading of 73,100 counts per second; assays from the winter program remain pending.
• Summer drilling will test the interpreted plunge of the Nova mineralized structure and include stepouts toward the unconformity while also evaluating additional high-priority conductive targets across the broader Dorado land package.
• An airborne MobileMT geophysical survey was recently completed over the Dorado project and results will be integrated into continuing geological interpretation and future drill targeting.

Summer 2026 drill program

The first objective of the summer campaign is to continue advancing the Nova discovery. Winter drilling successfully traced uranium mineralization across a one-kilometre structural corridor and provided a significantly improved understanding of the controls on mineralization. The current program is designed to test the interpreted plunge of the Nova system and evaluate its projected extension toward the unconformity. Together, these targets represent the next steps in systematically vectoring toward the core of the mineralized structure, which remains open along strike and at depth.

The second objective of the program is to evaluate several high-priority conductive targets identified by previous geophysical surveys but not yet drill tested. These targets represent an opportunity to define the mineralized system across a broader portion of the Dorado project. Drilling is helicopter supported, with accommodations and fuel logistics provided through Points North Landing.

About the Dorado project

The Dorado project is the flagship asset of the Purepoint and IsoEnergy 50/50 joint venture, encompassing more than 98,000 hectares of highly prospective uranium exploration ground in the eastern Athabasca basin. The project sits within one of the most prolific uranium districts on Earth, surrounded by world-class deposits including IsoEnergy's Hurricane -- the world's highest-grade indicated uranium resource. Underlain by the same fertile graphitic lithologies and fault structures that control high-grade uranium mineralization across the eastern basin, the project hosts multiple untested conductive corridors that exhibit structural and lithological characteristics associated with high-grade unconformity-related uranium deposits. Shallow unconformity depths across the property allow for efficient drilling and rapid follow-up.

Gamma logging

A Mount Sopris 2PGA-1000 downhole total gamma probe was utilized for radiometric surveying and reported counts per second.

About Purepoint Uranium Group Inc.

Purepoint Uranium Group is a uranium exploration company operating at the heart of the Athabasca basin -- the world's premier high-grade uranium district. Purepoint actively operates exploration programs on behalf of joint venture partnerships with three of the world's leading uranium companies: Cameco Corp., Orano Canada Inc. and IsoEnergy. Purepoint's strategy of advancing projects through partnerships with leading uranium companies allows the company to leverage technical expertise and partner financing while maintaining meaningful exposure to discovery success.

Purepoint operates the Dorado project under a 50/50 joint venture with IsoEnergy, where the Nova discovery returned confirmed assays of up to 8.1 per cent U3O8 and a mineralized corridor now extends to one kilometre. The company also operates the Hook Lake and Smart Lake projects under joint venture with Cameco and Orano Canada. Purepoint's wholly owned property portfolio includes additional exploration-stage uranium assets in the Athabasca basin region.

Additionally, Purepoint holds a promising VMS (volcanogenic massive sulphide) project optioned to and strategically positioned adjacent to Eldorado Gold's McIlvenna Bay project.
