PUREPOINT AND ISOENERGY JOINT VENTURE APPROVES 2026 PROGRAM TO ADVANCE THE NOVA DISCOVERY AT THE DORADO PROJECT

The Purepoint Uranium Group Inc. and IsoEnergy Ltd. joint venture has approved an expanded exploration program for 2026 following strong results from this year's drilling at the Dorado project. The Nova discovery returned uranium grades up to 8.1 per cent U3O8 (triuranium octoxide) over 0.4 metre within 2.1 metres of 1.6 per cent U3O8 in hole PG25-07A, confirming a steeply dipping uranium-bearing structure that remains open in all directions (see news release dated Sept. 18, 2025).

"The joint venture's approval of the 2026 program reflects the significance of the Nova discovery," said Chris Frostad, president and chief executive officer of Purepoint Uranium Group. "Each stepout delivered stronger mineralization, and the open northeastern extension has become our priority. The coming year allows us to advance Nova with purpose and begin evaluating additional high-priority zones across the Dorado project."

Highlights:

• The joint venture approved a dedicated exploration program to advance the Dorado project following up on this year's Nova discovery, which returned assays of 8.1 per cent U3O8 over 0.4 metre within 2.1 metres of 1.6 per cent U3O8.
• The approved program includes 17 holes totalling 7,450 metres across winter and summer campaigns:
  • The winter 2026 drill program (January to March) will focus on expanding Nova with 10 holes totalling approximately 4,300 metres.
  • The district-scale summer 2026 drill campaign (July to August) will test priority targets with seven holes totalling approximately 3,150 metres.
• Airborne magnetotellurics survey is planned for late winter or spring.
• Winter access and wetland drill pads will be established this month, including eight kilometres of existing trail and 10 kilometres of new trail construction.

Program summary

Winter 2026 -- Nova expansion

The winter drill program aims to advance the Nova discovery with 10 skidder-supported drill holes totalling 4,300 metres. Drilling will initially focus on the corridor between PG25-03 and PG25-07A, a distance of 800 metres, with 30-to-50-metre stepouts to the northeast, where the strongest mineralization was encountered. The Nova mineralization remains open in all directions.

Airborne magnetotellurics (MT) survey

A late winter or spring MT survey will be completed across the Serin, Laysan, Turaco, Q40, Q2 and Q48 grids to refine deeper structural targets.

Summer 2026 -- district-scale drilling across the Dorado project

A helicopter-supported drill program of seven holes totalling 3,150 metres will be undertaken in July and August to test conductive and structural targets across the Q23, Q24, Turaco, Laysan and Q40 grids.

The summer program will be subject to change pending winter drill results.

About the Dorado project

The Dorado project is the flagship project of the IsoEnergy-Purepoint 50/50 joint venture, a partnership encompassing more than 98,000 hectares of prime uranium exploration ground. The Dorado project includes the former Turnor Lake, Geiger, Edge and Full Moon properties, all underlain by graphite-bearing lithologies and fault structures favourable for uranium deposition.

Recent drilling by IsoEnergy east of the Hurricane deposit has intersected strongly elevated radioactivity in multiple holes. The anomalous radioactivity confirms the continuity of the fertile graphitic rock package and further highlights the opportunity for additional high-grade discoveries across the region.

The shallow unconformity depths across the Dorado project property -- typically between 30 and 300 metres -- allow for highly efficient drilling and rapid follow-up on results.
