07:21 AM EDT, 08/06/2025 (MT Newswires) -- IsoEnergy ( ISOU ) and Purepoint Uranium Group ( PTUUF ) on Wednesday said initial assays from the first two discovery drill holes completed at their joint venture Dorado project's Nova Discovery in Saskatchewan's Athabasca Basin have confirmed the presence of "high-grade" uranium mineralization.

The companies said assays from PG25-07, which intersected a much thicker mineralized interval and recorded the "strongest radioactivity readings to date," are still pending and expected in the coming weeks. Follow-up drilling to extend the mineralized trend northeast is planned for the winter, when frozen ground enables land-based access.

"These assays validate the significance of the mineralization first intersected at Q48," said Purepoint Uranium ( PTUUF ) Chief Executive Chris Frostad.

"With PG25-07 delivering the highest radioactivity readings so far, we believe its assays will provide valuable insight into how this discovery is evolving," said IsoEnergy ( ISOU ) Chief Executive Philip Williams.

Shares of IsoEnergy ( ISOU ) closed up 4.5% to $9.06 on Tuesday on the Toronto Stock Exchange. Purepoint shares closed up about 7% to $0.46 on Tuesday on the TSX Venture Exchange.
