Recent Company History

Over the last few months, Global Uranium has steadily advanced the Airline Project in Wyoming. In October 2025, it planned and executed a focused field program with radiometric surveying, mapping, and sampling. On November 26, 2025, the company significantly expanded the project to about 664 hectares, though shares fell 14.1%. A December update on completing the overall technical field program, including 56.27 line-kilometres of radiometrics, saw only a modest reaction. Today’s mapping completion and target refinement update fits this same exploration-build narrative.

Market Pulse Summary

This announcement details completion of detailed geological mapping at the Airline Project, confirming key units and highlighting two priority horizons associated with anomalous radioactivity and uranium-bearing minerals. It builds on a broader 2025 field campaign that collected 56.27 line-kilometres of radiometric data and 16 rock samples. Investors may focus on upcoming radiometric grids, geochemical assays, and mineralogical work, as well as how these datasets translate into concrete 2026 drill targets and future resource-definition milestones.

Key Terms

radiometric survey technical

"field program at Airline, which also included a radiometric survey, as well as hand"

A radiometric survey is a field measurement that maps natural radiation levels from rocks, soil or surface materials to locate concentrations of radioactive minerals like uranium or thorium. Think of it as sweeping an area with a radiation detector to reveal ‘hotspots’ beneath the ground; for investors, those hotspots can signal potential mineral resources, guide drilling programs, and affect a project’s economic value, regulatory requirements and environmental or safety liabilities.

geochemical assay technical

"hand samples for geochemical assay and mineralogical analysis."

A geochemical assay is a laboratory test that measures the amounts of metals or other elements in rock, soil or water samples collected from a property, much like a blood test reveals health markers in a body. Investors use assay results to judge whether a deposit contains enough valuable material and at what concentration, which directly affects a project’s potential value, development costs and exploration risk.

mineralogical analysis technical

"hand samples for geochemical assay and mineralogical analysis."

Mineralogical analysis is the study of which minerals are present in a rock or ore sample and how they are arranged, much like reading an ingredients list and seeing how components are mixed together. For investors it reveals the true quality and recoverability of a resource — telling you how easy or costly it will be to extract valuable metals, what processing methods are needed, and what environmental or technical risks might affect project economics.

autunite technical

"and uranium-bearing minerals such as autunite and a possible occurrence of"

Autunite is a naturally occurring yellow-green, radioactive mineral made of calcium, uranium and phosphate that typically forms flat, sheet-like crystals and often fluoresces under ultraviolet light. For investors, finding autunite can signal the presence of uranium-bearing rock or carry environmental contamination concerns, affecting a project’s potential revenue, cleanup costs and regulatory obligations—like finding rust on a car that hints at both value and repair bills.

metatorbernite technical

"uranium-bearing minerals such as autunite and a possible occurrence of metatorbernite,"

A green, crystalline mineral made of uranium, copper, phosphate and water that forms when uranium-bearing rocks break down and react with groundwater. Investors watch for metatorbernite because its presence in drill cores or mine waste can signal nearby uranium concentrations that affect resource value, or indicate long-lasting radioactive contamination and cleanup liabilities—like finding telltale crumbs that reveal what lies beneath the surface.

orthophotos technical

"northwest of the project area, where orthophotos indicate further potential for"

Orthophotos are aerial or satellite photographs that have been digitally corrected so distances, angles and shapes are accurate and consistent like a flat map, allowing you to measure features directly on the image. Investors use them for due diligence on land and property, infrastructure planning, and environmental risk assessment — think of an orthophoto as a high-resolution, true-to-scale blueprint of the ground that helps verify location, size and nearby hazards before committing capital.

National Instrument 43-101 regulatory

"and a “Qualified Person” under National Instrument 43-101, has reviewed and"

National Instrument 43-101 is a set of rules and guidelines that govern how mineral exploration and mining companies must report information about their projects. It ensures that the details shared with investors are accurate, consistent, and reliable—similar to how a detailed, verified blueprint ensures a building’s safety. This helps investors make informed decisions based on trustworthy information about a company's mineral resources.

Qualified Person regulatory

"Jared Suchan, Ph.D., P.Geo., Global Uranium’s Vice President of Exploration, and a “Qualified Person”"

A qualified person is someone with specialized knowledge, experience, and training in a particular field, allowing them to accurately assess and verify information or work. Their expertise helps ensure that reports, evaluations, or decisions are trustworthy and meet required standards. For investors, a qualified person provides confidence that the information they rely on is credible and properly validated.

Field Mapping Confirms Key Stratigraphic Contacts and Supports Upcoming Target Definition

CALGARY, Alberta, Dec. 09, 2025 (GLOBE NEWSWIRE) -- Calgary, Alberta — Global Uranium Corp. (CSE: GURN | OTC: GURFF | FRA: Q3J) (the “Company”) is pleased to announce that detailed geological mapping has been completed at the Airline Project in the Wind River Basin of central Wyoming. The mapping program represents the first component of the 2025 field program at Airline, which also included a radiometric survey, as well as hand samples for geochemical assay and mineralogical analysis. The results of those additional datasets will be reported as they become available.

The mapping was completed over one week by Big Rock Exploration in late October 2025 and improved the Company’s understanding of stratigraphy and structure at Airline. Multiple key geological units were validated across the study area (Figure 1). The Tertiary Wagon Bed Formation was confirmed to be widespread, displaying characteristic tuffaceous sandstones, interbedded tuffs, and granola- or popcorn-style weathering textures. Archean crystalline basement was mapped in several locations, including granite and monzogranite with abundant pegmatitic dikes, deep weathering, and bleaching near the overlying unconformity. Several Flathead Sandstone outcrops were identified on the western side of the study area. The contact between the Wagon Bed Formation and the Archean basement was mapped in several locations and remains one of the most important stratigraphic targets on the property, as earlier radiometric anomalies appear to originate close to this unconformity. Mapping also documented several arkosic sandstone outcrops that share similarities with the Wind River Formation, including porous textures and local iron-oxide nodules.

Two priority horizons have emerged from the fieldwork. The first is the unconformity between the Wagon Bed Formation and the Archean granite, where anomalous radioactivity, bleaching, and clay alteration were documented. The second is a discrete arkosic sandstone horizon informally referred to as the “Scorpion Unit,” where radiometric highs coincide with favorable textures and local structures. All accessible rocks on the property were oxidized to varying degrees, and no reduced ground was encountered. Several hand samples collected near the unconformity displayed intense clay alteration, hematite replacing former pyrite crystals, and uranium-bearing minerals such as autunite and a possible occurrence of metatorbernite, which was visible under ultraviolet light. Mineralogical identification is pending thin-section work; no conclusions have been drawn regarding mineral origin or paragenesis at this stage.

The mapping dataset will be integrated with the forthcoming ground-based radiometric grid, as well as geochemical assays and mineralogical results. A combined interpretation will support refined stratigraphic modelling and drill-target development for 2026. Future fieldwork may include additional focused mapping in the eastern and northeastern parts of the property, where further exposures of the unconformity and arkosic sandstone units may refine the exploration model. Additional work is also suggested in the northwest of the project area, where orthophotos indicate further potential for contact zones between granites and Eocene sediments.

Ungad Chadda, CEO of Global Uranium, commented: “This mapping program has strengthened our geological understanding of the Airline Project and confirmed several important features that warrant further work. These results will play a meaningful role in refining our next steps and informing our broader exploration strategy.”
