Aventis Energy Intersects Anomalous Radioactivity In Multiple Drill Holes At The Corvo Uranium Project And Concludes Inaugural Drill Program

(MENAFN- GlobeNewsWire - Nasdaq) VANCOUVER, British Columbia, April 20, 2026 (GLOBE NEWSWIRE) -- Aventis Energy Inc. (“ Aventis” or the“ Company”) ( CSE: AVE | FRA: C0O0 | OTC: VBAMF ) is pleased to announce that drilling activities have been completed at the Company's Corvo Uranium Project (“ Corvo” or the“ Project”) located near Wollaston Lake in northeastern Saskatchewan (Please see Figure 1). The inaugural drill program (the“ Program”) was designed to begin testing the Manhattan, Brooklyn and Tribeca target areas for basement hosted uranium mineralization.

The Project is currently under a three-year earn-in option agreement (the“ Option Agreement”) with Standard Uranium Ltd. (CSE: STND) (“ Standard”). Pursuant to the Option Agreement, the Company has been granted an option (the“ Option”) to earn a 75% interest in the Project by funding CAD$6M in exploration expenditures over three (3) years. The winter 2026 drill program was funded by the Company and operated by Standard.

Highlights of the Program

• A total of 2,457 metres were completed across ten (10) reconnaissance drill holes at the Manhattan, Brooklyn, and Tribeca target areas (Please see Figure 2).
• Multiple intervals of anomalous** radioactivity >300 counts per second (“ cps”) were intersected in seven (7) drill holes, totalling twenty-three (23) metres of composite radioactivity across all intervals. Multiple structural corridors remain open along strike.
• Anomalous** radioactivity is hosted within pegmatite, paragneiss, and granitoid orthogneiss units. Structural settings include hydrothermally altered fault zones and quartz-carbonate veining – all consistent with uranium mineralization in the region.
• Geochemical assays of drill core samples are pending. Several priority uranium targets remain along >25 km of untested strike length, and additional surface exploration and a second phase drilling program are being planned to follow up on radioactive intervals and continue testing regional drill targets across the Project.

“Our first round of drilling at Corvo returned twenty-three metres of cumulative radioactive intervals across ten holes, reinforcing the Project's exploration potential,” said Michael Mulberry, Chief Executive Officer & Director of Aventis.“Backed by Standard, we are in a strong position to build on these early results through expanded exploration efforts and additional drilling.”

2026 Drill Program – Preliminary Results

The winter drill Program was comprised of 2,457 metres across ten (10) drill holes, seven of which intersected anomalous** radioactivity within multiple intervals (Please see Table 1). One (1) drill hole was restarted due to difficult ground conditions.

The inaugural Program began testing three (3) high-priority target areas defined by data integration and modeling of a Project-wide Time-Domain Electromagnetic (“TDEM”) survey, a 5,185-station ground gravity survey, and surficial geological information. Radiometric*** results and drill hole information from the Program is provided in Table 1. Select drill core photos are provided in Figures 3 and 4.

Targets were selected and prioritized through an iterative approach working in collaboration with Convolutions Geoscience Corporation, targeting compelling geophysical signatures and favorable geological/structural settings. Recent prospecting and mapping across the Project outlined multiple mineralized outcrops and boulders, including the Manhattan showing which returned results up to 8.10% U3O8 at surface.¹

The nine (9) completed drill holes encountered highly favorable geological settings for basement-hosted uranium deposits, including:

• Twenty-three (23) metres of anomalous radioactivity (>300 cps) intersected across multiple intervals in seven (7) drill holes, often associated with structurally disturbed and altered rock.
• Fault zones were encountered in multiple holes, many featuring prominent brittle reactivation features including breccias, cataclasites, fault gouge, strong fracturing and local shearing all of which are consistent with uranium mineralization in the region.

Next Steps & Follow Up

Drill core samples have been collected systematically throughout all drill holes for whole-rock multi-element geochemical analysis and samples from zones of anomalous** radioactivity have been submitted to SRC Geoanalytical Laboratories in Saskatoon for U3O8 and Rare Earth Element (“ REE”) assay. These analytical results will be integrated with the detailed logging information and geophysical datasets to prioritize follow-up target areas for future drill testing, in addition to testing of numerous other priority regional targets.

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 and Ackio zone. Located just outside the current margin of the Athabasca Basin, Corvo boasts more than twenty-nine (29) km of structural corridors with multiple untested drill targets with minimal cover of glacial till.

This first pass drill program marks the first drilling on the Project in more than forty (40) years, and the results confirm critical metal fertility across multiple target areas. The Company and Standard will incorporate the results of the 2026 Program into the exploration strategy at Corvo for follow-up exploration programs targeting basement hosted uranium mineralization.

Qualified Person Statement

The scientific and technical information contained in this news release has been reviewed and approved by Sean Hillacre, P.Geo., President and VP Exploration of Standard and a“qualified person” as defined in NI 43-101 – Standards of Disclosure for Mineral Projects.

Geochemical assays are pending. Samples collected for analysis were sent to SRC Geoanalytical Laboratories in Saskatoon, Saskatchewan for preparation, processing, and ICP-MS or ICP-OES multi-element analysis using total and partial digestion and boron by fusion. 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 sample results will be subject to internal QA/QC protocols prior to subsequent release.

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 this 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 handheld RS-125 super-spectrometer and RS-120 super-scintillometer. 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. Because the orientation of mineralization is unknown, true widths are unknown and reported intervals represent core lengths. The RS-125 and RS-120 units supplied by Radiation Solutions Inc. (“ RSI”) have been calibrated on specially designed Test Pads by RSI. Standard maintains an internal QA/QC 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 to readings measured by the handheld scintillometers for QA/QC purposes.
