Purepoint Reports Winter 2026 Assays from

Dorado JV's Nova Target

Toronto, Ontario--(Newsfile Corp. - September 10, 2026) -

Purepoint Uranium Group Inc. (TSXV:

PTU) (OTCQB: PTUUF) ("Purepoint")

today reported assay results from the 2026 winter drill program

at the Nova Target on the 50/50 Dorado Joint Venture ("Dorado" or the "Project") with IsoEnergy Ltd.

Hole NV26-05 returned 1.65% U

O

over 0.3 metres 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 & CEO 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% U

O

over 0.3 metres from 390.4 metres.

NV26-03A returned 0.04% U

O

over 3.9 metres from 412.6 metres, including 0.10% U

O

over

0.4 metres, together with 0.79% U

O

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% U

O

. The interval recorded an average downhole gamma response of 61,070

cps over 0.3 m.

Hole NV26-03A intersected a broader mineralized interval grading 0.04% U

O

over 3.9 metres from

412.6 to 416.5 metres, including 0.10% U

O

over 0.4 metres from 415.1 to 415.5 metres. A separate

interval from 418.2 to 418.6 metres returned 0.79% U

O

over 0.4 metres and an average gamma

response of 37,050 cps.

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, that will be utilized for ongoing 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

Ltd.

Dorado hosts the Nova Discovery, where previous drilling returned assays of up to 8.1% U3O8 over 0.4

metres within 1.62% 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.
