GLOBAL URANIUM CORP. REPORTS RESULTS OF AIRBORNE ZTEM SURVEY AT ASTRO PROJECT, ATHABASCA BASIN

Global Uranium Corp. has released the results of the helicopter-borne Z-axis tipper electromagnetic (ZTEM) survey completed at the Astro project, located in the eastern Athabasca basin, Saskatchewan. The survey was conducted by Geotech Ltd. between April 13 and April 28, 2025, using 400 metre-spaced flight lines and perpendicular tie lines. In total, more than 1,480 line kilometres were flown across the property, with Condor Consulting providing real-time QA/QC, data processing and interpretation. Pursuant to the terms of an option agreement announced on April 9, 2025, the company has a right to earn up to an 80-per-cent interest in the Astro project.

A figure in the original version of this release presents the outcomes of the survey, highlighting a 25-kilometre northeast-trending conductive corridor in the northern half of Astro. This corridor is interpreted as a series of fault-controlled graphitic and pelitic zones, which are widely recognized as favourable hosts for uranium mineralization in the Athabasca basin. Several jogs and breaks were mapped along the trend, and cross-cutting structures were also identified that may act as fluid pathways and structural traps. A total of seven target zones (TZ) were defined. TZ1, TZ2 and TZ3 are considered high-priority because they coincide with the strongest conductivity responses and favourable magnetic settings along the main corridor. TZ4, TZ5, TZ6 and TZ7 are classified as lower priority, representing moderate conductivity trends that may reflect additional graphitic faults or altered metasediments.

These results mark the first time Astro has been covered by a property-wide EM survey, and they represent a major advancement in understanding the basement geology beneath the Athabasca sandstone.

Global Uranium and its JV (joint venture) partner with respect to the Astro project, Cosa Resources, will now refine their exploration strategy to advance Astro toward drill readiness. Recommended next steps include ground-based geophysics such as ambient noise tomography and EM surveys to prioritize strike segments and identify hydrothermal alteration systems, followed by drill testing of the highest-priority targets.

Ungad Chadda, chief executive officer of Global Uranium, commented: "The survey has identified a kilometre-scale conductive trend, a feature commonly associated with structural corridors in the region. Additional ground work and drilling will be required to determine whether this anomaly is associated with uranium mineralization."
