PUREPOINT REPORTS WINTER 2026 ASSAYS FROM DORADO JV'S NOVA TARGET

Purepoint Uranium Group Inc. has released assay results from the 2026 winter drill program at the Nova target on the 50/50 Dorado joint venture with IsoEnergy Ltd. Hole NV26-05 returned 1.65 per cent U3O8 (triuranium octoxide) over 0.3 metre from 390.4 metres at the unconformity. The nine-hole winter program intersected uranium mineralization in multiple holes across the Nova electromagnetic (EM) conductor and provided additional geologic and structural control for continued targeting. The summer drill program has now been completed, with results to be compiled and reported shortly.

"The winter 2026 program has materially improved our understanding of the Nova mineralization system," said Chris Frostad, president and chief executive officer of Purepoint Uranium. "The drilling produced additional uranium intercepts along the Nova EM conductor while providing the structural and geological data needed to better constrain its geometry and interpret. Our improved understanding of geologic controls and geophysical responses has provided us with increasingly specific drill targets as exploration advances."

Highlights:

• NV26-05 returned 1.65 per cent U3O8 over 0.3 metre from 390.4 metres;
• NV26-03A returned 0.04 per cent U3O8 over 3.9 metres from 412.6 metres, including 0.10 per cent U3O8 over 0.4 metre, together with 0.79 per cent U3O8 over 0.4 metres from 418.2 metres;
• Nine winter holes improved the geological and structural interpretation of Nova;
• The 2026 summer drill program is complete, with results to be reported shortly.

2026 Dorado winter drill program update

The 2026 winter program comprised nine drill holes designed to test the geological and structural controls associated with uranium mineralization at Nova and to refine the geometry of the conductor for subsequent exploration.

The strongest assay result was returned from NV26-05, where a 0.3-metre interval from 390.4 to 390.7 metres assayed 1.65 per cent U3O8. The interval recorded an average downhole gamma response of 61,070 counts per second over 0.3 metre.

Hole NV26-03A intersected a broader mineralized interval grading 0.04 per cent U3O8 over 3.9 metres from 412.6 to 416.5 metres, including 0.10 per cent U3O8 over 0.4 metre from 415.1 to 415.5 metres. A separate interval from 418.2 to 418.6 metres returned 0.79 per cent U3O8 over 0.4 metre and an average gamma response of 37,050 counts per second.

Additional uranium mineralization (Table 1) was returned from NV26-01, NV26-02, NV26-04, NV26-06A, NV26-07, NV26-08 and NV26-09A, confirming mineralization at multiple locations across the Nova target.

The winter drilling has refined Purepoint's interpretation of the Nova EM conductor and the associated geophysical responses, which will be utilized for continuing exploration drilling.

About the Dorado project

The Dorado project is located along the eastern margin of Saskatchewan's Athabasca basin in Canada. The property covers prospective structural corridors considered favourable for unconformity-related uranium mineralization and is operated by Purepoint under a 50/50 joint venture with IsoEnergy.

Dorado hosts the Nova discovery, where previous drilling returned assays of up to 8.1 per cent U3O8 over 0.4 metre within 1.62 per cent U3O8 over 2.1 metres. Uranium mineralization has been identified along a prospective structural corridor extending approximately one kilometre and is associated with intense alteration, structural disruption and graphitic basement rocks.

Exploration at Dorado is focused on improving the understanding of the geometry and continuity of the Nova mineralized system while evaluating additional priority targets across the property.

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 Aurora and Celeste blocks with IsoEnergy and 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.
