VANCOUVER, British Columbia, Oct. 29, 2026 (GLOBE NEWSWIRE) -- Aventis Energy Inc. (CSE: AVE | FRA: C0O0 | OTC: VBAMF) (“Aventis” or the “Company”) is pleased to report preliminary results from the fall 2026 surface exploration program (the “Program”) at the Corvo Uranium Project (“Corvo” or the “Project”) in northern Saskatchewan (Please see Figure 1). The Program was funded by Aventis and carried out by Standard Uranium Ltd. (TSX-V: STND) (“Standard Uranium”), the operator of the Project, under the three-year earn-in option agreement between the two companies.
Between October 1 and 9, 2026, crews mapped, prospected and sampled the historical uranium showings and other zones of interest across the 12,363-hectare Project. The work confirmed multiple zones of strong radioactivity at surface and found showings that had not previously been documented on the Project (Please see Figure 2).
Highlights
- Up to 48,000 cps at the Manhattan East showing. Handheld scintillometer readings of 20,000 to 48,000 counts per second (“cps”) in outcrop at the historical Manhattan East showing, where previous work reported readings up to 10,600 cps.1
- Strong readings beyond Manhattan East. Up to 36,000 cps at a known occurrence on the Brooklyn trend and 30,000 cps at Manhattan NE, approximately 130 m northeast of the Manhattan East showing (Please see Figure 2). In total, fifty-six (56) readings above the 300 cps anomalous* threshold were recorded, eight (8) of them above 10,000 cps.
- New showing on the Brooklyn trend. Prospecting discovered a previously undocumented radioactive occurrence reading up to 13,400 cps in altered pegmatite outcrop along the Brooklyn trend.
- The right host rocks. Mapping along the structural and electromagnetic (“EM”) trends confirmed deformed and hydrothermally altered basement rocks, including metasedimentary, calc-silicate and granitic units, favourable hosts for uranium and rare earth element (“REE”) mineralization.
- Assays pending. Nine (9) outcrop grab samples are at Saskatchewan Research Council Geoanalytical Laboratories (“SRC”) in Saskatoon for uranium, REE and whole-rock analysis.
- Next steps. Geophysical surveys are being designed to refine drill targets ahead of a second drill program planned for 2027.
Michael Mulberry, Chief Executive Officer of Aventis, commented: “The team took the Manhattan East showing from a historical 10,600 cps to 48,000 cps, found a new showing on the Brooklyn trend, and tied the surface geology to last winter’s drill holes. All of this data will provide valuable feedback as we build new drill targets.”
Fall 2026 Surface Program
The Program ran from October 1 to 9, 2026, and focused on ground-truthing historical uranium showings and extending them along the Manhattan and Brooklyn trends, with additional coverage of the Dorward, Unnamed, Finger, Hook and Sheppard Lake areas. It followed up on the winter 2026 inaugural drill program, the first drilling on the Project in more than forty (40) years, which returned anomalous uranium in all nine (9) completed holes.
- More than one hundred (100) geological observations, structural measurements and scintillometer readings were recorded from outcrop across the Project.
- A total of fifty-six (56) scintillometer readings above the 300 cps anomalous* threshold were recorded, eight (8) of them above 10,000 cps (Please see Figure 2).
- At the Manhattan East showing (Dorward Lake area), readings of 20,000 cps to 48,000 cps were measured in outcrop. Mineralization occurs as black vitreous minerals in structures with secondary iron oxide alteration (Please see Figure 3). A further reading of 30,000 cps was recorded approximately 130 m to the northeast (Manhattan NE), where mineralization is associated with a fracture system in paragneiss (Please see Figure 5). Samples were collected at both locations.
- Along the Brooklyn trend, a new showing in altered pegmatitic orthogneiss returned readings up to 13,400 cps (Please see Figure 4), and a known occurrence returned readings up to 36,000 cps (Please see Figure 2).
- Nine (9) outcrop grab samples were submitted to SRC (as defined below) for whole-rock, uranium and REE geochemical analysis. Results will be released once received and reviewed.
- Readings were taken with handheld RS-120 Super-Scintillometers and RS-125 Super-Spectrometers manufactured by Radiation Solutions Inc.

Next Steps
Assay results from the nine (9) grab samples will be released when they are received from SRC and reviewed by the qualified person. Standard Uranium is designing supplementary geophysical programs to refine drill targets, integrating the new surface data with the winter 2026 drilling and geochemical datasets. A second drill program is planned for 2027.
About the Corvo Uranium Project
Corvo lies just outside the eastern margin of the Athabasca Basin near Wollaston Lake, Saskatchewan, 60 km due east of Cameco’s McArthur River mine and 45 km northeast of Atha Energy’s Gemini Mineralized Zone. The Project is comprised of fourteen (14) mineral dispositions totalling 12,363 hectares and covers more than 29 km of structural corridors defined by magnetic lows and EM conductors, with bedrock under minimal glacial till cover and shallow drill targets.
Aventis entered into a three-year earn-in option agreement with Standard Uranium on May 8, 2025, under which Aventis may earn a 75% interest in the Project. Standard Uranium is the operator of the Project.
The Project targets shallow, high-grade** basement-hosted uranium of the type found at the Rabbit Lake deposit and the nearby Gemini and Ackio Mineralized Zones. Surface work has identified several outcrop showings of mineralized veins and fractures, including the Manhattan showing, where 2025 sampling returned up to 8.10% U3O8 at surface.2 The winter 2026 inaugural drill program, the first drilling on the Project in more than forty years, completed 2,457 metres in ten (10) reconnaissance holes at the Manhattan, Brooklyn and Tribeca target areas. Nine (9) holes were completed and one was abandoned due to ground conditions. All nine (9) completed holes returned anomalous uranium, including 13 metres of highly anomalous uranium (>100 ppm U, partial digestion). Intervals are drilled core lengths and true widths are not known.
Qualified Person
The scientific and technical information in this news release has been reviewed and approved by Sean Hillacre, P.Geo., President and VP Exploration of Standard Uranium, the operator of the Project, and a qualified person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects.
Samples were submitted to SRC Geoanalytical Laboratories in Saskatoon, Saskatchewan, accredited to ISO/IEC 17025:2017 by the Standards Council of Canada (“SRC”), for preparation and ICP-MS or ICP-OES multi-element analysis by total and partial digestion, with boron by fusion. Blanks, standard reference materials and repeats were inserted into the sample stream at regular intervals under the operator’s quality assurance/quality control (“QA/QC”) protocols. Assay results remain subject to QA/QC review before release.
Scintillometer readings reported in this news release were measured in cps with handheld RS-125 super-spectrometers and RS-120 super-scintillometers supplied by Radiation Solutions Inc. (“RSI”). The units are calibrated by RSI on purpose-built test pads, and the operator checks for instrument drift against three internal test pads of known radioactivity. Scintillometer readings are not uniformly or directly related to the uranium grade of the rock measured and are only a preliminary indication of the presence of radioactive minerals. Pending assays will determine uranium content.
Historical results from previous operators cited in this news release have not been verified by the Company or by a qualified person, and investors should not place undue reliance on them. The Company treats historical results as an exploration guide only. Grab samples are selected samples and may not represent the underlying mineralization.
* Readings above 300 cps on a handheld RS-125 Super-Spectrometer are considered anomalous.
** Uranium mineralization above 1.0 wt% U3O8 is considered high-grade.
