Aventis, Standard Uranium update Corvo Project, Saskatchewan and Sting Project, Newfoundland
Aventis Energy Inc. [CSE: AVE] has provided an update from its 2025 exploration program at the Corvo uranium project, Athabasca basin, Saskatchewan, currently under a three-year earn-in option agreement with Standard Uranium Ltd. [TSXV: STND; OTCQB: STTDF; Frankfurt: FWB:9SU0]. From July 4, 2025, to July 16, 2025, the company completed a detailed mapping and sampling program across historical uranium showings and zones of interest on the project.
Highlights: Off-scale radioactivity at surface: verification of strong radioactivity at the historical Manhattan showing with hand-held scintillometer measurements more than 65,535 counts per second (cps) at surface, in addition to 112 further occurrences of highly anomalous radioactivity up to 13,500 cps across the project.
Discovery of new radioactive showings: scintillometer prospecting uncovered previously undocumented radioactive occurrences across the project in favourable rock types for uranium and rare earth element (REE) mineralization.
Favourable uranium host rocks: geological mapping along structural and electromagnetic (EM) trends across the project confirmed the presence of deformed and hydrothermally altered basement lithologies, including metasedimentary, calc-silicate, and granitic rocks.
Continuing exploration: an extensive ground gravity survey is being planned for Q4 (fourth quarter) 2025, designed to identify density anomalies potentially representing hydrothermal alteration systems coincident with newly refined EM (electromagnetic) conductor trends across the project. A diamond drill program is being planned for Q1 (first quarter) 2026 to begin testing targets developed and ranked through the detailed programs executed in 2025.
Michael Mulberry, CEO, commented: “We are proud to announce preliminary results from our 2025 exploration program at the Corvo project. With the identification of strong radioactivity at the Manhattan showing and favourable results from geological mapping along key trends at the project, we are well positioned to complete a near-term ground gravity survey.”
Beginning July 4, 2025, and concluding July 16, 2025, the technical team completed a detailed mapping, prospecting and sampling program to ground-truth historical uranium showings at surface on the project.
A total of 30 outcrop and boulder grab samples have been submitted to Saskatchewan Research Council Geoanalytical Laboratories in Saskatoon, Sask., for whole-rock, uranium and REE (rare earth element) geochemical analysis. Results will be released and incorporated into the first NI 43-101 technical report on the project.
More than 160 detailed geological observations, structural measurements and scintillometer readings were taken from several outcrops across the project within the T-Lake, Dorward, Unnamed, Finger, Snout, Hook and Sheppard Lake areas.
Prospecting confirmed several uraniferous outcrops and boulders across the project, including the Manhattan showing (1.19 to 5.98% U3O8) and SMDI showing 2052 (0.137% U3O8 and 2,300 parts per million (ppm) thorium (Th)). Off-scale radioactivity more than 65,535 cps was measured at the Manhattan showing.
A total of 112 hand-held scintillometer readings of anomalous radioactivity more than 300 cps were recorded, including six measurements more than 10,000 cps at surface. Prospecting for radioactive boulders and outcrop was completed using hand-held RS-120 superscintillometers and RS-125 superspectrometers manufactured by Radiation Solutions Inc. (RSI).
At the Corvo uranium project, uranium mineralization is present along a strike length of 800 metres in historical drill holes TL-79-3 (0.057% U3O8 over 3.5 metres) to TL-79-5 (0.065% U3O8 over 0.1 m). Recent expansion of the project adds multiple new data points of uranium anomalism in the south, including surface sample JBWLR011, returning 1,420 ppm uranium (U.)
Supplementary geophysical surveys across the project are being designed to further refine drill targets for an inaugural drill program. The company plans to complete a high-resolution ground gravity survey across the main conductive trends on the project, aiming to identify potential hydrothermal alteration halos which could be related to basement-hosted uranium mineralization.
Earlier this year, Standard Uranium contracted Axiom Exploration Group Ltd. in partnership with New Resolution Geophysics to carry out a helicopter-borne Xcite time domain electromagnetic (TDEM) and total field magnetic survey over the project. The survey totalled approximately 1,380 line-km with a traverse line spacing of 100 m 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 km of conductive trends on the project.
The magnetic survey component of the TDEM survey contributes to definition of potential fault systems and structural trends not previously identified across the project related to historical uranium showings at surface and in historical drill holes.
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.
Natural gamma radiation in diamond drill core reported in this news release was measured in cps 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 company considers uranium mineralization with concentrations greater than 1.0 weight per cent U3O8 to be high grade. The company considers radioactivity readings greater than 65,535 cps on a hand-held RS-125 superspectrometer to be off scale. The company considers radioactivity readings greater than 300 cps on a hand-held RS-125 superspectrometer to be anomalous.
Aventis Energy is advancing its Corvo uranium and Sting copper projects. 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% U3O8 over 1.05 m) and TL-79-5 (0.065% U3O8 over 0.15 m) (high-grade uranium at surface with the Manhattan showing (1.19 to 5.98% U3O8) and SMDI showing 2052 (0.137% U3O8 and 2,300 ppm Th).
The Sting copper project, Newfoundland, covers approximately 12,700 hectares and recently had results of 54.8 metres at 0.32% copper starting at a depth of 27.0 metres, with higher-grade intervals including six samples (more than 0.5 m length) ranging from 0.96% to 5.43% Cu (high-grade samples of 0.5 metres at 2.85% Cu and 0.5 metres at 1.92% Cu with an additional broader interval of 31.1 metres at 0.27% Cu).
