AVENTIS ENERGY RECEIVES DRILL PERMITS AND INITIATES GROUND GRAVITY SURVEY ON THE CORVO URANIUM PROJECT

Aventis Energy Inc. has received exploration permits for the Corvo uranium project. Work programs under the 18-month permits will include high-resolution geophysical surveys and the company's first drill program on the project beginning in January, 2026.

The company contracted MWH Geo-Surveys (Canada) Ltd. to complete an extensive 50-metre-by-200-metre ground gravity survey covering more than 29 kilometres of conductive strike length, which will aid in identifying density anomalies that may represent hydrothermal alteration systems coinciding with uranium fertile electromagnetic conductor trends. MWH mobilized to the project on Nov. 24, 2025, and the survey will be composed of more than 5,000 individual gravity measurement stations.

Following completion of the gravity survey, a skid-assisted diamond drill program totalling approximately 3,000 metres is planned for January, 2026, which will mark the first drill program on the project in more than 40 years. Drilling will target high-priority areas including the never-before-drilled Manhattan showing and other newly identified radioactive occurrences across the project. Outcrop grab samples collected earlier this year returned uranium assays reaching a maximum of 8.10 per cent triuranium octoxide at the Manhattan showing.

Michael Mulberry, chief executive officer of the company, commented: "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 with the opportunity to complete a high-resolution geophysical survey and a drilling program."

2025 exploration programs

Earlier this year, the company contracted Axiom Exploration Group Ltd. in partnership with New Resolution Geophysics to carry out a helicopter-borne Xcite time domain electromagnetic and total field magnetic survey over the project. The survey totalled approximately 1,380 line kilometres with a traverse line spacing of 100 metres and tie-line spacing of 1,000 metres. The airborne TDEM survey outlines several kilometres of conductive anomalies and magnetic features in bedrock, effectively enhancing the resolution of more than 29 kilometres of conductive trends on the project.

Continuing geophysical interpretation and modelling are being completed to integrate historical surveys with newly collected data sets, which will provide high-priority drill targets and significantly derisk the project prior to modern drilling in 2026.

In July of 2025, Standard Uranium Ltd. as operator completed the company's first prospecting and mapping program on the project with the objective of ground-truth sampling historical uranium showings including the Manhattan showing, which returned results up to 59,800 parts per million uranium (total digestion). The company identified zones of off-scale radioactivity (greater than 65,535 counts per second on a hand-held RS-125 superspectrometer) and collected hand samples, which returned results ranging from 0.72 per cent to 8.10 per cent U3O8, the highest grades ever reported on the project. New drill targets were developed based on previously undocumented radioactive showings, and a National Instrument 43-101 technical report was filed on the project, highlighting high-grade surface mineralization at the Manhattan showing.

The company believes the project is highly prospective for the discovery of shallow, high-grade basement-hosted uranium mineralization akin to the Rabbit Lake deposit and the recently discovered GMZ. Located just outside of the current margin of the Athabasca basin, the project boasts shallow drill targets with bedrock under minimal cover of glacial till.

Qualified person statement

The scientific and technical information contained in this news release has been reviewed, verified and approved by Sean Hillacre, PGeo, president and vice-president, exploration, of Standard Uranium, a qualified person as defined in NI 43-101 (Standards of Disclosure for Mineral Projects).

Samples collected for analysis were sent to SRC Geoanalytical Laboratories in Saskatoon, Sask., for preparation, processing, and ICP-MS or ICP-OES multielement analysis using total and partial digestion and boron by fusion. Radioactive samples were tested using the ICP1 uranium multielement exploration package plus boron. All samples marked as radioactive upon arrival to the lab were also analyzed using the U3O8 assay (reported in weight per cent). SRC is an ISO/IEC 17025:2005 and Standards Council of Canada certified analytical laboratory. Blanks, standard reference materials and repeats were inserted into the sample stream at regular intervals in accordance with Standard Uranium's quality assurance/quality control protocols. All samples passed internal QA/QC protocols, and the results presented in this release are deemed complete, reliable and repeatable.

Historical data disclosed in this news release relating to sampling results from previous operators are historical in nature. Neither the company nor a qualified person has yet verified these data, and, therefore, investors should not place undue reliance on such data. The company's future exploration work may include verification of the data. The company considers historical results to be relevant as an exploration guide and to assess the mineralization, as well as economic potential of exploration projects. Any historical grab samples disclosed are selected samples and may not represent true underlying mineralization.

Natural gamma radiation from rocks reported in this news release was measured in counts per second using a hand-held RS-125 superspectrometer and RS-120 superscintillometer. Readers are cautioned that scintillometer readings are not uniformly or directly related to uranium grades of the rock sample measured and should be treated only as a preliminary indication of the presence of radioactive minerals. The RS-125 and RS-120 units supplied by Radiation Solutions Inc. have been calibrated on specially designed test pads by RSI. Standard Uranium maintains an internal quality assurance/quality control procedure for calibration and calculation of drift in radioactivity readings through three test pads containing known concentrations of radioactive minerals. Internal test pad radioactivity readings are known and regularly compared with readings measured by the hand-held scintillometers for QA/QC purposes.

About Aventis Energy Inc.

Aventis Energy is a mineral exploration company dedicated to the development of strategic projects composed of battery, base and precious metals in stable jurisdictions. The company is working to advance its Corvo uranium and Sting copper project.

The Corvo uranium property has historical drill holes intersected multiple intervals of uranium mineralization, notably along a strike length of 800 metres between historical drill holes TL-79-3 (0.116 per cent U3O8 over 1.05 m) and TL-79-5 (0.065 per cent U3O8 over 0.15 m). High-grade uranium at surface includes at the Manhattan showing 1.19 to 5.98 per cent U3O8 and at the SMDI showing 2052 0.137 per cent U3O8 and 2,300 parts per million thorium).

The Sting copper project covers approximately 12,700 hectares and recently had results of 54.8 m at 0.32 per cent Cu starting at a depth of 27.0 m, with higher-grade intervals including six samples (greater than or equal to 0.5-metre length) ranging from 0.96 per cent to 5.43 per cent Cu. High-grade samples included 0.5 m at 2.85 per cent Cu and 0.5 m at 1.92 per cent Cu with an additional broader interval of 31.1 m at 0.27 per cent Cu.
