Aventis, Standard Uranium plan gravity survey at Corvo

Executive Summary

• Aventis Energy reported off‑scale surface radioactivity (> 65,535 cps) at the historic Manhattan showing and recorded 112 additional anomalous readings up to 13,500 cps across the Corvo uranium project.
• Surface grab samples returned high uranium grades (Manhattan: 1.19–5.98 wt% U₃O₈; SMDI showing 2052: 0.137 wt% U₃O₈ and 2,300 ppm Th).
• The company plans a high‑resolution ground gravity survey in Q4 2025 and a diamond drill program in Q1 2026 to test the newly identified targets.

Key Details

• Program period: July 4 – July 16 2025; detailed mapping, prospecting, and sampling of historic uranium showings.
• Radioactivity results:
• Off‑scale hand‑held scintillometer measurement > 65,535 cps at Manhattan showing.
• 112 anomalous readings > 300 cps; six measurements exceeded 10,000 cps.
• Surface sampling:
• 30 outcrop and boulder grab samples submitted to Saskatchewan Research Council for whole‑rock, uranium and REE analysis (results pending NI 43‑101 report).
• Manhattan showing: 1.19–5.98 wt% U₃O₈.
• SMDI showing 2052: 0.137 wt% U₃O₈, 2,300 ppm Th.
• Historical drill data: Uranium mineralization over an 800‑m strike length; TL‑79‑3 (0.057 wt% U₃O₈ over 3.5 m) to TL‑79‑5 (0.065 wt% U₃O₈ over 0.1 m).
• Geophysical work:
• Completed helicopter‑borne Xcite TDEM and magnetic survey (~1,380 km line, 100 m spacing) identifying > 29 km of conductive trends.
• Planning high‑resolution ground gravity survey Q4 2025 to locate density anomalies linked to hydrothermal alteration.
• Future exploration:
• Ground gravity survey slated for Q4 2025.
• Diamond drill program targeted for Q1 2026 to test targets refined from mapping, scintillometer data, and geophysical surveys.
• Qualified Person: Sean Hillacre, P.Geo., President & VP Exploration, Standard Uranium (NI 43‑101 qualified).

Notable Quotes

“We are proud to announce preliminary results from our 2025 exploration program at the Corvo project. With the identification of strong radioactivity at the Manhattan showing and favourable results from geological mapping along key trends at the project, we are well positioned to complete a near‑term ground gravity survey.” – Michael Mulberry, CEO, Aventis Energy

Materiality Assessment: Material – Positive (the release provides substantive new exploration data indicating high‑grade uranium potential and outlines concrete next‑step drilling plans).
