AVENTIS ENERGY ANNOUNCES FILING OF NI 43-101 TECHNICAL REPORT ON THE CORVO URANIUM PROJECT

Aventis Energy Inc. option partner Standard Uranium Ltd. has filed a technical report entitled "Technical Report on the Corvo Property -- Northeastern Saskatchewan, Canada," prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, on the Corvo project. The report was co-prepared by Axiom Exploration Group Ltd. and has an effective date of Oct. 24, 2025. The report is available on SEDAR+ and is published on Standard's website.

Qualified persons

All scientific and technical information contained in the report summarizing the work completed to date on the project has been reviewed and approved by Troy Marfleet, PGeo, of Axiom, co-author of the report and independent qualified person under the definitions established by NI 43-101. The report was co-written by Sean Hillacre, MSc, PGeo, president and vice-president, exploration, of Standard, a qualified person under the definitions established by NI 43-101. The report does not contain a mineral resource estimate (MRE) in accordance with NI 43-101.

The qualified persons have reviewed and verified that the technical information with respect to all the company's exploration efforts to date contained in the report is accurate and have approved the written disclosure of such information. The report is intended to be read as a whole, and sections should not be read or relied upon out of context.

About the Corvo project

The company currently has an active definitive agreement with Standard to acquire a 75-per-cent interest in the 12,265-hectare project located in the eastern Athabasca basin region, targeting high-grade basement-hosted uranium. The project is situated 1.5 kilometres outside the current margin of the Athabasca basin, approximately 45 kilometres northeast of the Gemini mineralized zone (GMZ).

The company believes the project is highly prospective for the discovery of high-grade basement-hosted uranium mineralization akin to the Rabbit Lake deposit and the recently discovered GMZ. Several outcrop showings of mineralized veins and fractures are present on the project, notably the Manhattan showing, which returned recent sample results up to 8.10 weight per cent U3O8 (triuranium octoxide) at surface and has never been drill tested. The project is also prospective for rare earth element (REE) mineralization, potentially providing additional value upside.

Qualified person statement

The scientific and technical information contained in this news release has been reviewed, verified and approved by Mr. Hillacre, president and vice-president, exploration, of Standard and a qualified person as defined in NI 43-101.

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.

Note: The company considers uranium mineralization with concentrations greater than 1.0 weight per cent U3O8 to be high grade.

About Aventis Energy Inc.

Aventis Energy is a mineral exploration company dedicated to the development of strategic projects comprising battery, base and precious metals in stable jurisdictions. The company is working to advance its Corvo uranium project 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 metres) and TL-79-5 (0.065 per cent U3O8 over 0.15 metre). High-grade uranium at surface with the Manhattan showing (1.19 to 5.98 per cent U3O8 ) and 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 metres at 0.32 per cent copper starting at a depth of 27.0 metres, 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 copper. High-grade samples of 0.5 metre at 2.85 per cent copper and 0.5 metre at 1.92 per cent copper with an additional broader interval of 31.1 metres at 0.27 per cent copper.
