Snapshot	In May 2025, Global Uranium released a Scoping Study on the Hansen Deposit at the Tallahassee Uranium Project, outlining a compelling development pathway. The Hansen Project is the largest and highest-grade deposit within the Tallahassee Creek Uranium District, which is perhaps one of the largest undeveloped uranium resources in the United States. The Study confirmed there are no federal, state, or local regulatory barriers to development, further strengthening the project's profile. ROM ore would be subjected to on-site beneficiation prior to shipment to an offsite mill. Global Uranium will continue to de-risk and advance the project through targeted technical programs. These include further test work, refinement of mining parameters, metallurgical recovery assessments, and geotechnical studies. Together, these activities will progress Project toward potential development as a cornerstone asset within Global Uranium's US portfolio.

Summary:

The geological history of the Tallahassee Creek area conforms to the general understanding of the regional and local geology. The Precambrian is extensively faulted into north-south trending horst and graben blocks. These fault blocks appear to have controlled not only the past position of meandering streams, but all subsequent streams. The present site of Tallahassee Creek and its valley appears to reflect the old drainage system at the time of Echo Park deposition.

A widespread bentonitic clay layer hydraulically separates the Echo Park Formation from the overlying sediments. Uranium mineralization across the Tallahassee Uranium District is found in the conglomerates of the Echo Park and Tallahassee Creek Formations. Continuity of mineralization is strong along the long axis of the Project, but less so in the perpendicular direction. Toward the edge of the deposits, mineralization becomes thin and grade decreases. To date, five mineralized deposits have been identified. From northwest to southeast, they are the Noah, northwest Taylor, Boyer, Hansen, and Picnic Tree deposits. The largest is the Hansen deposit.

Deposit Type and Mineralization
The deposits that make up the Project are tabular sandstones associated with redox interfaces. The mineralization is hosted in Tertiary sandstones and/or clay bearing conglomerates within an extinct braided stream, fluvial system or paleochannel. Mineralization occurred post sediment deposition when oxygenated uraniferous groundwater moving through the host rocks came into contact with redoxinterfaces, the resultant chemical change caused the precipitation of uranium minerals. In parts of the project the paleochannel has been covered by Tertiary volcanic rocks and throughout the Project basement consists of Precambrian plutonic and metamorphic rocks. The volcanic and Precambrian rocks are believed to be contributing sources of the uranium.

Uranium mineralization is found in two forms. A large portion of mineralization is found in the interstitial spaces of the sandstones, strongly associated with naturally occurring organic materials co-located with the uranium. In addition, and related chemically, uranium is found in a patina coating on individual grains of sand.
