Global Uranium Corp. Plans Ambient Noise Tomography Survey at Astro Project

CALGARY, March 26, 2026 - Global Uranium Corp. (CSE: GURN | OTC: GURFF | FRA: Q3J) (the "Company") is pleased to announce its intention to complete an Ambient Noise Tomography ("ANT") survey with CAUR Technologies at the Astro Project ("Astro"), located in the eastern Athabasca Basin, Saskatchewan. The Company holds an option to acquire an 80% interest in Astro from Cosa Resources Corp. ("Cosa"), the project's underlying owner and operator, subject to the satisfaction of certain earn-in requirements.

The planned ANT program builds on the Company's 2025 helicopter-borne ZTEM survey, which identified a large 25-kilometre conductive corridor and outlined seven target zones, including three high-priority areas. These results significantly improved the Company's understanding of the project and highlighted areas with strong potential for uranium mineralization.

The upcoming ANT survey will focus on the most prospective areas identified to date, including the AS-1 target. The program is designed to further refine these targets by identifying key geological features at depth and improving the Company's ability to prioritize drill locations.

Importantly, this survey represents a key step in advancing Astro toward planning for future drilling. The data collected is expected to help define high-confidence drill targets and support the design of follow-up ground geophysical programs, with the aim of positioning the Company for its first drill campaign on the project.

CAUR Technologies was selected by Cosa Resources Corp. in its capacity as operator of the Astro Project. Subject to scheduling and field conditions, the survey is expected to begin in early June, with completion anticipated in July and final results expected in August. These results are expected to directly inform next steps, including additional ground work and drill targeting.

Ungad Chadda, CEO of Global, stated, "Last year's results outlined a large and compelling target area at Astro, and this ANT survey is an important next step in refining those targets. With a 25-kilometre corridor and multiple high-priority zones already identified, we are continuing to build toward defining our initial drill targets. We believe Astro has the scale and geological setting we look for in the Athabasca Basin, and this program moves us closer to assessing that potential."
