Global Uranium Corp. Announces Completion of Geological Mapping at the Airline Project in Wyoming

Executive Summary

• Completed detailed geological mapping of the Airline Project in Wyoming, enhancing understanding of stratigraphy and structure.
• Identified two priority horizons: the Wagon Bed–Archean unconformity and the “Scorpion Unit” arkosic sandstone horizon, both showing favorable alteration and radiometric anomalies.
• Mapping results will be integrated with upcoming radiometric grids, geochemical assays, and mineralogical work to refine drill‑target models for 2026.

Key Details

• Mapping conducted by Big Rock Exploration over one week in late October 2025; validated multiple key geological units across the study area.
• Confirmed widespread Tertiary Wagon Bed Formation with characteristic tuffaceous sandstones, interbedded tuffs, and popcorn‑style weathering textures.
• Mapped Archean crystalline basement (granite, monzogranite) with pegmatitic dikes, deep weathering, and bleaching near the unconformity.
• Identified Flathead Sandstone outcrops on the western side and several arkosic sandstone outcrops resembling the Wind River Formation.
• Priority Horizon 1: Unconformity between Wagon Bed Formation and Archean granite – shows anomalous radioactivity, bleaching, clay alteration, and uranium‑bearing minerals (autunite, possible metatorbernite).
• Priority Horizon 2: “Scorpion Unit” – discrete arkosic sandstone horizon with radiometric highs, favorable textures, and local structures.
• Hand samples from the unconformity exhibit intense clay alteration, hematite replacing pyrite, and visible uranium minerals under UV light; mineralogical identification pending thin‑section analysis.
• No reduced ground encountered; all accessible rocks are oxidized to varying degrees.
• Mapping dataset will be combined with forthcoming ground‑based radiometric grid, geochemical assay results, and mineralogical analyses for integrated interpretation.
• Planned 2026 activities include refined stratigraphic modelling, drill‑target development, additional focused mapping in eastern/northeastern portions of the property, and exploration of northwest zones where orthophotos suggest further contact zones.
