AVENTIS ENERGY ANNOUNCES FALL SURFACE EXPLORATION PROGRAM AT THE CORVO URANIUM PROJECT

Aventis Energy Inc. plans for additional ground exploration at the Corvo uranium project, currently under a three-year earn-in option agreement with Standard Uranium Ltd. Exploration crews are scheduled to mobilize to site on Oct. 1, 2026, to begin a detailed mapping and sampling program across historical uranium showings and newly identified zones of interest.

Highlights

• High-grade uranium at surface: A prospecting, mapping and geochemical sampling program is planned for October, 2026 to expand on newly identified and historical uranium-bearing outcrops including the Manhattan showing (1.19 to 8.10 per cent U3O8 (triuranium octoxide)) and SMDI showing 2052 (0.137 per cent U3O8 and 2,300 ppm (parts per million) Th (thorium)).
• Integration with drilling results: The results of the inaugural drill program on the project clearly outlined a robust multikilometre uranium-bearing mineralized system across the Manhattan, Brooklyn and Tribeca target areas. Drilling confirmed the presence of significant fault systems linked to uranium enrichment and prospective hydrothermal alteration in the basement rock, which will be further investigated in detail at surface during the program.
• Follow-up targets and next steps: Following the integration of additional surface exploration results with drilling and geophysical data sets, a second phase drilling program is being planned to continue testing along strike of mineralized drill holes in addition to priority regional drill targets. Several priority uranium targets remain along greater than 25 kilometres of structural strike length.

The fall 2026 program will focus on prospective areas around and along strike of successful drilling results from the winter 2026 drill campaign. Analytical results from the company's first-ever drill campaign at Corvo confirmed anomalous uranium in all nine completed drill holes. Results returned a total of 55 metres of weakly anomalous uranium (greater than 10 ppm U (uranium), partial), including 23 metres of moderately anomalous uranium (greater than 50 ppm U, partial), and including 13 metres of highly anomalous uranium (greater than 100 ppm U, partial).

Michael Mulberry, chief executive officer and director of Aventis, commented: "The fall program is the natural next step following the success of our inaugural drill campaign at Corvo. With crews returning to the ground in October, we have the opportunity to tie detailed mapping and sampling directly to the structures, alteration, and uranium enrichment identified in drilling, and to expand on high-grade surface showings such as Manhattan. Combined with the ongoing geophysical work, this will sharpen our drill targets ahead of the second phase of drilling planned for 2027, and we look forward to continuing to advance the project alongside Standard Uranium."

2026 fall exploration program

Standard's technical team is scheduled to mobilize to the project on Oct. 1, 2026, to undertake a detailed mapping, prospecting, and sampling program to expand on known uranium showings and collect additional geological information at surface which can be linked to drill results. Collected grab samples will be transported to Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, Sask., for geochemical analysis. The company will finance the exploration program as part of the option agreement dated May 8, 2025, and Standard will act as operator.

Supplementary geophysical work programs across the project are also being designed to further refine drill targets for a 2027 drill program. Continuing geophysical interpretation and modelling are planned throughout the remainder of 2026 to integrate drilling, geophysics and prospecting data sets, which will further derisk drill targets across the project prior to follow-up drilling next year.

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 Gemini mineralized zone. Located just outside the current margin of the Athabasca basin, Corvo boasts shallow drill targets with bedrock under minimal cover of glacial till. Several outcrop showings of mineralized veins and fractures are present on the project, notably the Manhattan showing that returned modern sample results up to 8.10 per cent U3O8 at surface.

Qualified person statement

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

Samples collected for analysis were sent to SRC Geoanalytical Laboratories (SRC) in Saskatoon, Sask., for preparation, processing and ICP-MS multielement analysis using total and partial digestion and boron by fusion. Basement samples were tested with ICP-MS2 uranium multielement exploration package plus boron. All sandstone samples and basement samples marked as radioactive upon arrival to the lab were also analyzed using the U3O8 assay (reported in wt. per cent). Basement rock split interval samples range from 0.1 to 1.0 metre. 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's quality assurance/quality control (QA/QC) 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.

About Aventis Energy Inc.

Aventis Energy is a mineral exploration company dedicated to the development of strategic projects comprised 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 with the Manhattan showing (with outcrop samples grab samples returning up to 8.10 per cent U3O8) and SMDI showing 2052 (0.137 per cent U3O8 and 2,300 ppm Th).

The Sting copper project covers approximately 3,700 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 m length) ranging from 0.96 per cent to 5.43 per cent Cu. High-grade samples of 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.
