Toronto, Ontario--(Newsfile Corp. - January 26, 2026) - Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) today announced that drilling has commenced at the Dorado Project as part of the Purepoint and IsoEnergy Ltd. joint venture, marking the start of a focused winter program designed to expand the high-grade Nova Uranium Discovery and advance additional priority targets across the property.

The winter drill program represents the first phase of a fully approved multi campaign exploration program at Dorado and is a direct follow up to the 2025 Nova Discovery, which returned uranium grades of up to 8.1% U₃O₈ over 0.4 metre within 2.1 metres of 1.6% U₃O₈ in hole PG25 07A. Drilling will focus on systematic step-outs along the steeply dipping mineralized structure, which remains open in all directions.

"The decision to aggressively advance drilling at Dorado this year reflects both the strength of the Nova Discovery and the joint venture's confidence in its growth potential," said Chris Frostad, President & CEO of Purepoint Uranium Group. "Nova has delivered increasing uranium grades as we step-out and has quickly emerged as a priority discovery within our portfolio. The current drill program is designed to test scale, continuity, and the broader structural corridor that hosts the uranium mineralization."

Highlights

• Drilling has commenced on the 2026 winter exploration program at the Dorado Project following the high-grade Nova Discovery
• Winter program includes up to 10 drill holes totaling approximately 4,300 metres focused on expanding Nova
• Drilling will target the corridor between holes PG25-03 and PG25-07A, an 800-metre strike length with strongest mineralization currently toward the northeast
• The Nova mineralized structure remains open along strike and at depth
• Winter access and drill pad construction have been completed in advance of drilling
• The winter program represents the first phase of a broader 2026 program that also includes district scale summer drilling and geophysical surveying

Winter 2026 Nova Expansion Program

The winter drill program is utilizing skidder supported drilling to test 30 to 50 metre step-outs along the interpreted mineralized structure hosting the Nova Discovery. Initial drilling will focus on the northeastern extension of the system where the strongest uranium mineralization has been encountered to date. Results from this phase will guide follow up drilling later in the winter and inform target prioritization for the summer drilling campaign.

Advancing a District Scale Opportunity

Beyond Nova, the Dorado Project hosts multiple priority target areas defined by conductive corridors, fault structures, and favorable graphitic lithologies. A planned airborne magnetotellurics survey later this winter or early spring will refine deeper structural targets across several grids, supporting continued district scale evaluation of the joint venture land package.

A helicopter supported summer drill program is planned to test additional targets across the Dorado Project, subject to winter results.

About the Dorado Project

The Dorado Project is the flagship asset of the Purepoint and IsoEnergy 50 percent joint venture and encompasses more than 98,000 hectares of highly prospective uranium exploration ground in the eastern Athabasca Basin. The project includes the former Turnor Lake, Geiger, Edge, and Full Moon properties and is underlain by fertile graphitic lithologies and fault structures favourable for high grade uranium mineralization. Shallow unconformity depths across the property allow for efficient drilling and rapid follow up on exploration results.
