PUREPOINT COMMENCES 2026 DRILLING PROGRAM AT DORADO FOLLOWING NOVA URANIUM DISCOVERY

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 multicampaign exploration program at Dorado and is a direct follow-up to the 2025 Nova discovery, which returned uranium grades of up to 8.1 per cent triuranium octoxide over 0.4 metre within 2.1 metres of 1.6 per cent U3O8 in hole PG25 07A. Drilling will focus on systematic stepouts 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 and chief executive officer 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.
• The inter program includes up to 10 drill holes totalling 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 stepouts 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 favourable 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-per-cent 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.
