Aventis Energy Kicks Off Winter Diamond Drilling at Corvo Uranium Project

Aventis Energy is moving ahead with a winter drilling campaign at the Corvo Uranium project, aiming to reveal what lies beneath the surface. In a region long known for high-grade uranium discoveries, the company is returning to diamond drilling for the first time in decades. The central question is whether the earlier signals seen in the Manhattan target hold up when tested at depth.

The focus centers on the Manhattan zone in the eastern Athabasca Basin, where past work highlighted notable radioactivity. In uranium exploration, such signals often represent the initial hint before the true mineralized zones are confirmed deeper underground.

This program seeks to address these open questions in a structured way. Planned activity encompasses roughly 2,500 to 3,000 meters of diamond drilling across 8 to 10 holes. The crew has been on site since February 6, with drilling formally commencing on February 9. The winter campaign is slated to run for about five to six weeks.

The targets: modern data meets historical indicators

A notable aspect of the program is that it marks Corvo’s first diamond drilling effort in more than four decades. This time, the objectives will be sharpened using up-to-date geophysical information. The initiative follows a 2025 program that included time-domain electromagnetic (TDEM) surveys and ground gravity measurements.

Should investors sell immediately? Or is it worth buying Aventis Energy?

The aim is to test shallow uranium mineralization hosted in the basement rock. Surface evidence already exists: grab samples have reportedly returned up to 8.10% U3O8. Whether such grades are coherent, continuous, and drill-worthy will be clarified by the current campaign.

Key data at a glance:
- Drill scope: 2,500–3,000 meters
- Holes: 8–10
- Target area: Manhattan Zone
- Schedule: winter campaign of roughly 5–6 weeks
- Partners: Convolutions Geoscience (Targeting), Standard (Drilling Operations)

Market backdrop: shares face headwinds

Thus far, investor confidence has been modest. The stock trades around €0.13, below the 50-day moving average of €0.15. This suggests that traders are waiting for tangible drilling results before positioning themselves more decisively.

Looking ahead, the cadence of the next few weeks will be crucial. If the campaign proceeds as planned, results could arrive into March and help situate the Manhattan Zone—and, by extension, the broader Corvo project—more clearly.
