Aventis Energy Sets Stage for 2026 Drilling Campaign at Corvo Uranium Project

Aventis Energy CA05358H1091

Aventis Energy is preparing to commence a pivotal drilling program at its Corvo Uranium Project in 2026, marking a significant operational milestone. This initiative represents the first drilling activity in over four decades within this section of the eastern Athabasca Basin. The core objective is to investigate whether exceptionally high-grade uranium samples previously identified at surface level correspond to a substantial mineralized system at depth.

The upcoming winter 2026 exploration campaign is slated for approximately 3,000 meters of diamond drilling, focusing on the Manhattan Zone. This specific target area, situated within the project's basement geology, has never been drill-tested. Its prospectivity is underscored by compelling historical and recent surface findings.

Operational execution will be managed by Standard Uranium in partnership with Aventis Energy, utilizing a winterized drill rig designed for Saskatchewan's challenging climate. The project is strategically located roughly 60 kilometers east of the prolific McArthur River Mine, operated by regional giant Cameco.

Extensive preparatory work throughout 2025 has laid the groundwork for this campaign. A high-resolution ground gravity survey, encompassing more than 5,000 measurement points across 29 kilometers of conductive structures, was completed. This dataset is now instrumental in guiding precise drill hole placement.

The High-Grade Surface Evidence Driving the Target

The decision to prioritize the Manhattan Zone is heavily influenced by robust surface sample results from the 2025 field program. Rock grab samples from the "Manhattan Showing" returned uranium assays as high as 8.10% U₃O₈, representing the highest grades ever recorded across the project area.

Historical sampling from the same zone further reinforces its potential, with past measurements detecting up to 59,800 parts per million (ppm) uranium. The planned drilling aims to determine if these surface expressions are indicative of a continuous, high-grade uranium system extending into the subsurface.

Market Context and Financial Backing

The announcement of the forthcoming drill program follows a period of volatility for the company's shares. After trading near its 52-week low in early January, the stock has seen a modest recovery. It currently trades at 0.14 euros, remaining noticeably below its 50-day moving average of 0.17 euros—a reflection of cautious market sentiment.

From an operational standpoint, Aventis states it is adequately financed for the program. In late 2025, the company secured aggregate proceeds of approximately CAD $2.5 million through several flow-through private placements, priced at CAD $0.41 per share—a significant premium to the current trading level. Funds from an October 2025 financing are explicitly earmarked for project exploration, providing the financial foundation for the imminent campaign.

A Data-Integrated Approach to Discovery

The company employs a modern, data-driven exploration strategy that synthesizes multiple geological and geophysical inputs. This integrated method focuses on identifying zones of hydrothermal alteration, which are key structural indicators for high-grade uranium mineralization in the Athabasca Basin.

Key components of this technical approach include:

• Airborne Survey Data: A helicopter-borne Xcite™ Time-Domain Electromagnetic (EM) and magnetic survey completed in 2025, which delineated several kilometers of conductive anomalies and distinct magnetic structures.
• Ground Gravity Data: The high-resolution gravimetric survey from Q4 2025, which reveals density variations and provides clues for potential alteration systems.
• Historical Data Reinterpretation: Ongoing analysis and integration of legacy geophysical datasets with newly acquired information.

This consolidated data package is used to define drill targets designed to test geological models with an optimized probability of success.

Permitting and Anticipated Timeline

The necessary exploration permits were granted in late November 2025 for an 18-month term. These permits authorize both high-resolution geophysical work and diamond drilling, affording Aventis scheduling flexibility to adapt the program as needed.

Initial insights are expected during the drilling phase itself. Downhole gamma probe readings, which measure the radioactivity of the core, will provide early indications prior to laboratory assays. Visual logging for geological features such as rock bleaching or color changes will offer immediate feedback for model validation. Definitive laboratory assay results are anticipated by the end of Q1 2026. These results will be critical in confirming whether the high-grade surface expressions of the Manhattan Zone continue at depth, potentially outlining an economically significant uranium discovery.
