Purepoint JV approves 2026 Dorado exploration program

Executive Summary

• Purepoint Uranium Group and IsoEnergy Ltd. have approved an expanded 2026 exploration program for the Dorado project, driven by strong results from the Nova discovery.
• The Nova discovery previously returned uranium grades up to 8.1% U3O8 over 0.4m within 2.1m of 1.6% U3O8, confirming a steeply dipping structure that remains open in all directions.
• The 2026 program consists of 17 drill holes totaling 7,450 metres, split into a winter campaign focused on expanding the Nova discovery and a summer campaign for district-scale target testing.

Key Details

• Nova Discovery Assays: Hole PG25-07A returned 8.1% U3O8 over 0.4m within 2.1m of 1.6% U3O8.
• Total Program Scope: 17 drill holes totaling 7,450 metres across winter and summer campaigns.
• Winter 2026 Campaign (January–March):
  • 10 skidder-supported drill holes totaling approximately 4,300 metres.
  • Focus: Expanding the Nova discovery, specifically the corridor between PG25-03 and PG25-07A (800m distance).
  • Methodology: 30-to-50-metre stepouts to the northeast to test the open extension.
• Summer 2026 Campaign (July–August):
  • 7 helicopter-supported drill holes totaling approximately 3,150 metres.
  • Focus: District-scale testing of priority targets across Q23, Q24, Turaco, Laysan, and Q40 grids.
  • Targets: Conductive and structural targets.
  • Note: Program subject to change pending winter drill results.
• Geophysical Surveys: Airborne magnetotellurics (MT) survey planned for late winter or spring across Serin, Laysan, Turaco, Q40, Q2, and Q48 grids to refine deeper structural targets.
• Infrastructure: Establishment of winter access and wetland drill pads, including 8km of existing trail and 10km of new trail construction.
• Project Context: Dorado is a 50/50 joint venture between Purepoint and IsoEnergy, encompassing over 98,000 hectares. Recent drilling east of the Hurricane deposit has intersected strongly elevated radioactivity, confirming the continuity of fertile graphitic rock packages.

Notable Quotes

• "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."
