Vancouver, British Columbia — February 11, 2026 — Leads & Copy — Standard Uranium Ltd. has started drilling at its Corvo Uranium Project near Wollaston Lake in northeastern Saskatchewan. The project covers 12,364 hectares.
Field crews arrived at the project on February 6th, and drilling commenced on February 9th. Aventis Energy Inc. is funding the drill program, which Standard Uranium is operating.
Aventis has the option to earn a 75% interest in the project by funding CAD$6 million in exploration expenditures over three years, according to the three-year earn-in option agreement.
The current program anticipates approximately 2,500-3,000 meters across eight to ten drill holes targeting shallow high-grade basement-hosted uranium mineralization, beginning with the Manhattan target area. The program is expected to last five to six weeks.
Drill plans focus on high-priority uranium targets refined by geophysical work completed in 2025, along with prospecting and confirmation of strong radioactivity at surface (up to 8.10% U3O8 grab samples at Manhattan1) within ideal uranium host rocks. The diamond drill will focus on high-priority target areas along prospective XciteTM electromagnetic corridors overlain by high-resolution ground gravity data.
Sean Hillacre, President & VP Exploration for Standard Uranium, said the drill is spinning on the Corvo project for the first time in more than 40 years. He added that this program marks the first drill holes ever at the Manhattan showing, which returned uranium grades up to 8.10% U3O8 in surface samples from their prospecting program in 2025.
The Corvo Project is located 60 km east of Cameco’s McArthur River mine and 45 km northeast of Atha Energy’s Gemini Mineralized Zone.
The Standard Uranium team arrived on site February 9, 2026, and diamond drilling on the first hole at Corvo in more than 40 years is currently underway. Corvo covers an area of 12,364 hectares across 14 mineral claims, located along highway 905 on the eastern margin of the Athabasca Basin.
Targets were selected and prioritized through an iterative approach working with Convolutions Geoscience Corporation. Recent prospecting and mapping across the Project outlined multiple outcrops of favorable uranium host-rocks, including radioactive metasediments and orthogneiss. Structural measurements and radioactivity mapping has further refined drill targets in the 2026 target areas.
Targets are ranked and prioritized based on geophysical signature, geological/structural setting, proximity to surficial uranium occurrences of interest, and the Company’s recent prospecting and mapping campaign.

*The Company considers uranium mineralization with concentrations greater than 1.0 wt.% U3O8 to be “high-grade”.
**The Company considers radioactivity readings greater than 65,535 counts per second (cps) on a handheld RS-125 Super-Spectrometer to be “off-scale”.
***The Company considers radioactivity readings greater than 300 counts per second (cps) on a handheld RS-125 Super-Spectrometer to be “anomalous”.
