Global Uranium begins ANT survey at Astro

2026-06-26 14:06 ET - News Release

Mr. Ungad Chadda reports

GLOBAL URANIUM CORP. COMMENCES AMBIENT NOISE TOMOGRAPHY SURVEY AT THE ASTRO URANIUM PROJECT, SASKATCHEWAN

Global Uranium Corp. has commenced an ambient noise tomography (ANT) survey has commenced at the Astro project, located in the eastern Athabasca basin in Saskatchewan. The company holds an option to acquire up to an 80-per-cent interest in Astro from Cosa Resources Corp., the project's underlying owner and operator, subject to the satisfaction of certain earn-in requirements. The ANT survey forms part of the next phase of exploration following Global's completion of the phase 1 earn-in requirements under its option agreement with Cosa.

The ANT survey is the next step in advancing Astro following the completion of a 2025 airborne geophysical program, which defined a significant east-northeast-trending conductive corridor across the project, providing the foundation for the current follow-up work. The coming ANT survey will be completed by CAUR Technologies of Quebec, Canada, and is designed to deliver high-resolution shear wave velocity models to support geological interpretation and drill targeting by helping delineate lithological contrasts, structural features and alteration zones within the lower Athabasca sandstone and upper basement rocks.

The survey will focus on the AS-1 target area, which covers a significant portion of a 25-kilometre-long conductive corridor defined by Cosa's 2025 project-wide airborne survey. Conductive corridors of this type are considered important exploration targets in the Athabasca basin and are commonly associated with structural settings that host uranium deposits elsewhere in the basin. The survey design includes the deployment of 300 seismic sensors and is expected to take approximately two months to complete. Results from the survey are expected to help Global and Cosa identify and prioritize the most prospective areas for additional exploration, including potential follow-up ground electromagnetic surveying and future diamond drill targeting.

Ungad Chadda, chief executive officer of Global, stated: "We are pleased to see the next phase of work now under way at Astro. This survey is an important step in helping us narrow our focus across a large and highly prospective target area in the Athabasca basin. Our goal is to keep advancing Astro in a disciplined way, using the right technical work at each stage to build toward future drill targets.
