VANCOUVER, BC, Oct. 15, 2025 /PRNewswire/ - Urano Energy Corp. (CSE: UE) (OTCQB: UECXF) (the "Company" or "Urano") announced today the completion of its initial evaluation of the Green River Uranium Project in Emery County, Utah. The assessment, based on detailed historical data from Atlas Corp., confirms a significant historical uranium inventory and identifies multiple high-priority areas for follow-up exploration.

An independent consulting mining engineer to Atlas Corp. estimated historical resources of 247,711 lbs. U₃O₈ grading 0.13%, along with additional historical resources of approximately 1.4 million lbs. U₃O₈ at 0.13%¹ using USGS classification terminology "indicated reserve" and "inferred reserve" respectively applicable at that time. The Green River Project benefits from an active Small Mining Operations permit, extensive underground mine maps, and Atlas drill logs, providing Urano with a strong foundation for expansion and validation.

"The addition of these drilled-out historical uranium resources represents a real asset for Urano," said Jason Bagg, Chief Executive Officer of Urano Energy. "As we continue analyzing our database of uranium properties across Utah and Colorado, we expect to significantly grow our historical uranium inventory. The Green River project alongside our other Atlas-era holdings offers excellent potential to identify and upgrade historical estimates to NI 43-101 mineral resource standards over the coming quarters."

¹ Historical estimates were prepared for Atlas Corp. using the classification categories indicated reserves and inferred reserves consistent with 1976 USGS principles of classification applicable at that time. The above historical estimates were not prepared using the current definitions of "mineral reserve" and "mineral resource" as those terms are used in National Instrument 43-101 ("NI 43-101") and defined under current CIM standards. The historical estimate is considered reliable and is relevant for the purpose of conducting data analysis and future exploration on the Properties. Additional review and analysis of the available data, and if necessary additional exploration work, including confirmatory drilling and sampling, is required to verify and upgrade the historical estimates as a current mineral resource or mineral reserve. A qualified person has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. The Company is not treating the historical estimate as current mineral resources or mineral reserves. No specific analyses of V₂O₅ are available for Company's Green River deposits, as at the time of reserve estimation, Atlas Corp. considered the concentration of vanadium to be too low for economic production. However, references to Indicated and Inferred Ore are considered similar to indicated and inferred mineral resources.

Green River Uranium Project Highlights

Expansion Potential: Numerous ore-grade drill hole intercepts remain untested, suggesting strong potential for near-surface discoveries.
Strategic Location: Situated in Utah's San Rafael River District, the third-most productive uranium district in the state, which has produced over 4.48 million lbs. of U₃O₈ historically.²
Extensive Land Position: 49 claims covering approximately 1,009 acres, representing about 4.5% of Urano's Utah-Colorado portfolio.

About the Green River Uranium Project

The Green River Uranium Project is a historically productive site located in the San Rafael District, a region renowned for its uranium-rich geology. The property was historically operated by Atlas Corp., in the late 1970's and early 1980's, which also ran its own processing facilities in the Utah–Colorado uranium belt. Mineralization occurs in the Salt Wash Member of the Jurassic Morrison Formation, where uranium occurs primarily as coffinite and uraninite hosted in organic-rich sandstones at depths between 15 and 70 feet. The property is fully permitted for small-scale underground mining and surface disturbance, enabling Urano Energy to initiate targeted operations with efficiency and minimal regulatory delay.

Atlas's historical reserve data, reviewed and verified by an independent registered mining engineer, provides a robust dataset for Urano's modern evaluation. The Company intends to prioritize Green River for future confirmatory drilling and NI 43-101 technical reporting.

Cautionary Note Regarding Historical Estimates

The historical reserve estimates reported herein were prepared by Atlas Corp. and audited by an independent registered mining engineer. These estimates were not prepared under current NI 43-101 or CIM standards and should not be relied upon as current mineral resources or reserves. Urano has not yet completed the work necessary to verify or classify these historical estimates and is not treating them as current mineral resources or reserves. Further data review and confirmatory exploration will be required to upgrade the estimates.
