GLOBAL URANIUM ANNOUNCES COMPLETION OF ANT SURVEY FIELDWORK AT THE ASTRO PROJECT

Global Uranium Corp. has completed fieldwork for the ambient noise tomography (ANT) survey at the Astro project in the eastern Athabasca basin, Saskatchewan. Seismic sensors have been recovered, and the program has advanced to data processing and interpretation to support the next phase of exploration. CAUR Technologies completed the fieldwork, with Cosa Resources Corp. serving as project operator. The program included 21 days of seismic monitoring, completed in July, followed by sensor retrieval. The work is intended to help Global and Cosa prioritize areas for follow-up ground electromagnetic (EM) surveying and future drill targeting.

The ANT survey focused on the AS-1 target area, which covers a substantial portion of the approximately 25-kilometre-long, east-northeast-trending conductive corridor identified by the 2025 airborne ZTEM survey. ANT uses recordings of ambient seismic noise to develop models of subsurface shear-wave velocity. These models can help refine interpretations of rock units, structural features, and potential alteration within the lower Athabasca sandstone and upper basement rocks. The ANT interpretation will be assessed alongside the existing Z-axis tipper electromagnetic (ZTEM) data set to select priority areas for proposed ground EM surveying during the upcoming winter field season. Ground EM would provide additional definition of conductive targets ahead of potential drilling. The scope and timing of follow-up work remain subject to the completed ANT interpretation, contractor availability, funding and required approvals.

"Completing the fieldwork moves Astro into the next stage of evaluation," said Ungad Chadda, chief executive officer of Global Uranium. "We are focused on using the ANT results alongside the existing airborne geophysics to prioritize follow-up work and build toward well-supported drill targets."

Global expects to provide a further update following completion and review of the ANT interpretation. Geophysical anomalies are exploration targets and do not, on their own, establish the presence of uranium mineralization.
