Purepoint reports winter 2026 assays from Nova at Dorado JV

Toronto, Ontario--(Newsfile Corp. - September 10, 2026) - Purepoint Uranium Group Inc. (TSXV: PTU) (OTCQB: PTUUF) ("Purepoint") today reported assay results from the 2026 winter drill program at the Nova Target on the 50/50 Dorado Joint Venture ("Dorado" or the "Project") with IsoEnergy Ltd. Hole NV26-05 returned 1.65% U₃O₈ over 0.3 metres from 390.4 metres at the unconformity. The nine-hole winter program intersected uranium mineralization in multiple holes across the Nova electromagnetic (EM) conductor and provided additional geologic and structural control for continued targeting. The summer drill program has now been completed, with results to be compiled and reported shortly.

"The winter 2026 program has materially improved our understanding of the Nova mineralization system," said Chris Frostad, President & CEO of Purepoint Uranium. "The drilling produced additional uranium intercepts along the Nova EM conductor, while providing the structural and geological data needed to better constrain its geometry and interpret. Our improved understanding of geologic controls and geophysical responses has provided us with increasingly specific drill targets as exploration advances."

Highlights

NV26-05 returned 1.65% U₃O₈ over 0.3 metres from 390.4 metres.

NV26-03A returned 0.04% U₃O₈ over 3.9 metres from 412.6 metres, including 0.10% U₃O₈ over 0.4 metres, together with 0.79% U₃O₈ over 0.4 metres from 418.2 metres.

Nine winter holes improved the geological and structural interpretation of Nova.

The 2026 summer drill program is complete with results to be reported shortly.

2026 Dorado Winter Drill Program Update

The 2026 winter program comprised nine drill holes designed to test the geological and structural controls associated with uranium mineralization at Nova and to refine the geometry of the conductor for subsequent exploration.

The strongest assay result was returned from NV26-05, where a
