Aventis receives exploration permits for Corvo

Executive Summary

• Aventis Energy Inc. has received exploration permits for its Corvo uranium project, enabling the initiation of a ground gravity survey and a planned diamond drill program starting in January 2026.
• The company contracted MWH Geo-Surveys to conduct an extensive 50m x 200m ground gravity survey covering over 29km of conductive strike length, aiming to identify density anomalies and hydrothermal alteration systems.
• The upcoming drill program will target approximately 3,000 meters, marking the first drilling on the project in over 40 years, with specific focus on the Manhattan showing and other newly identified radioactive occurrences.

Key Details

• Permits and Timeline: Exploration permits received for an 18-month work program; ground gravity survey mobilized on Nov. 24, 2025; first drill program scheduled for January 2026.
• Gravity Survey Specifications: Conducted by MWH Geo-Surveys (Canada) Ltd.; covers >29 km of conductive strike length; consists of >5,000 individual gravity measurement stations; aims to identify density anomalies coinciding with uranium fertile electromagnetic conductor trends.
• Drilling Plan: Skid-assisted diamond drill program totaling ~3,000 meters; targets high-priority areas including the never-before-drilled Manhattan showing and other newly identified radioactive occurrences.
• Recent Sampling Results (Manhattan Showing): Outcrop grab samples returned uranium assays reaching a maximum of 8.10% U3O8; earlier July 2025 prospecting/mapping returned results up to 59,800 ppm uranium (total digestion) and off-scale radioactivity (>65,535 cps).
• 2025 Airborne Survey: Contracted Axiom Exploration Group Ltd. and New Resolution Geophysics for helicopter-borne Xcite time domain electromagnetic (TDEM) and total field magnetic survey; covered ~1,380 line km with 100m traverse and 1,000m tie-line spacing; outlined several kilometers of conductive anomalies and magnetic features.
• Geological Context: Project located just outside the Athabasca basin margin; prospective for shallow, high-grade basement-hosted uranium mineralization similar to Rabbit Lake and GMZ deposits; bedrock under minimal glacial till cover.
• Historical Data: Historical drill holes intersected multiple intervals of uranium mineralization, notably TL-79-3 (0.116% U3O8 over 1.05m) and TL-79-5 (0.065% U3O8 over 0.15m); high-grade surface historical data includes Manhattan showing (1.19 to 5.98% U3O8) and SMDI showing (0.137% U3O8 and 2,300 ppm thorium).
• Qualified Person: Sean Hillacre, PGeo, president and vice-president, exploration of Standard Uranium, verified and approved the scientific and technical information.
• Laboratory Analysis: Samples sent to SRC Geoanalytical Laboratories (Saskatoon, Sask.) for ICP-MS/ICP-OES analysis and U3O8 assays; lab is ISO/IEC 17025:2005 certified.

Notable Quotes

• "We are very pleased to have received drill permits for our Corvo uranium project. Receiving the permits builds on our 2025 exploration program efforts, which saw a helicopter-borne Xcite time domain electromagnetic and total field magnetic survey over Corvo, equipping us with invaluable information to continue our exploration efforts. The permits provide us to complete a high-resolution geophysical survey and a drilling program." — Michael Mulberry, CEO
