Global Uranium completes 20% earn-in at Astro
Cosa Resources Advances Astro JV Milestone Amidst Athabasca Exploration Push

Executive Summary
- Global Uranium Corp. completed Phase 1 requirements of its option agreement with Cosa Resources, securing an initial 20% interest in the Astro project.
- The earn-in structure allows Global to reach up to 80% ownership over five phases via exploration financing, cash payments, and share issuances.
- Geophysical progress on Astro includes a 25-kilometre conductive corridor identified by ZTEM surveying, fully funded by Global Uranium.
- Future work plans include ambient noise tomography surveys to refine structural targets for drilling.
- Concurrently, Cosa reported anomalous radioactivity at Murphy Lake North (MLN) on April 13, with intercepts up to >13,900 cps, though chemical assays remain pending.
- The company maintains joint ventures with Denison Mines (70/30 split) on Darby and MLN projects.
Material Impact
- The Astro earn-in completion is a positive validation of the partnership structure but does not introduce new value creation beyond previously announced terms.
- It confirms Global Uranium is fulfilling its funding obligations, reducing immediate cash burn risk for Cosa on this specific project.
- However, the MLN radioactivity results (April 13) lack confirmed uranium grades ("assays are pending"), limiting their materiality until chemical verification occurs.
- The news reinforces operational momentum but lacks a definitive discovery or resource estimate that would warrant a "Material - Positive" rating.
- Investor confidence is bolstered by the continued participation of strategic partners (Denison, Global), yet dilution risks from warrants and future earn-in share issuances persist.
