Purepoint, IsoEnergy begin drilling at Dorado

Executive Summary

• Purepoint Uranium Group has commenced its 2026 winter drilling program at the Dorado project, a joint venture with IsoEnergy Ltd., following the high-grade Nova uranium discovery.
• The initial phase involves up to 10 drill holes totaling approximately 4,300 metres, designed to expand the Nova discovery and test stepouts along the mineralized structure.
• The program targets an 800-metre strike length between holes PG25-03 and PG25-07A, with a focus on the northeastern extension where the strongest mineralization has been encountered.

Key Details

• Program Scope: The winter drill program consists of up to 10 drill holes totaling approximately 4,300 metres.
• Drilling Method: Utilizing skidder-supported drilling to test 30- to 50-metre stepouts along the interpreted mineralized structure.
• Target Area: Initial drilling focuses on the corridor between holes PG25-03 and PG25-07A, an 800-metre strike length with the strongest mineralization currently toward the northeast.
• Nova Discovery Context: The program is a direct follow-up to the 2025 Nova discovery, which returned uranium grades of up to 8.1% triuranium octoxide over 0.4 metres within 2.1 metres of 1.6% U3O8 in hole PG25 07A.
• Structural Status: The Nova mineralized structure remains open in all directions, including along strike and at depth.
• Future Plans: This winter program is the first phase of a broader 2026 strategy that includes district-scale summer drilling and geophysical surveying.
• Geophysics: A planned airborne magnetotellurics survey is scheduled for later this winter or early spring to refine deeper structural targets across several grids.
• Project Assets: The Dorado project encompasses more than 98,000 hectares in the eastern Athabasca basin, including former Turnor Lake, Geiger, Edge, and Full Moon properties.
• Joint Venture: The project is a 50/50 joint venture between Purepoint Uranium Group and IsoEnergy Ltd.

Notable Quotes

• "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."
