RENO, Nev., May 05, 2026 (GLOBE NEWSWIRE) -- Eagle Nuclear Energy Corp. ("Eagle" or the "Company") (NASDAQ:NUCL), a next-generation nuclear energy company that owns the largest conventional, measured and indicated uranium deposit in the United States, today announced that it has launched a comprehensive environmental baseline studies campaign prior to the commencement of the previously announced 27,000 ft Pre-Feasibility Study ("PFS") related drill program at its flagship Aurora Uranium Project ("Aurora" or the "Project") site located along the Oregon–Nevada border.

Eagle's VP of Operations, Vishal Gupta, stated, "Initiating environmental baseline studies marks an important milestone in the responsible advancement of Aurora toward a PFS. These studies are designed to collect critical environmental data across multiple disciplines, including hydrology, hydrogeology, surface water quality, groundwater quality, flora and fauna, wetlands delineation, geochemistry, meteorology, and cultural heritage. Once collected, this data will support environmental impact assessments, mine design optimization, and future permitting activities at Aurora. We are committed to developing Aurora in a manner that meets or exceeds regulatory standards and reflects best practices in environmental stewardship."

Additional Details Regarding Environmental Baseline Studies

As part of this campaign, Eagle has, through its lead permitting manager, SLR International Corporation ("SLR"), started the permitting and procurement process for a 10-meter-high meteorological ("MET") station that is expected to be installed at the Project by early-June. Once installed, the MET station will collect ambient weather-related data, including wind speed (both horizontal and vertical), wind direction, temperature (and temperature contrasts), relative humidity, barometric pressure, and solar radiation. The data collected from the MET station will be used to support air-quality permitting and other related air-quality studies at Aurora.

On behalf of Eagle, SLR has also initiated detailed delineation of wetlands and other jurisdictional aquatic resources across the specific areas at Aurora where the upcoming PFS-related drill program will be conducted. Field teams will identify and map wetland boundaries, streams, and other waters, and assess their functional characteristics, hydrologic connectivity, and ecological value. The resulting data will inform project design, support avoidance and minimization strategies, and serve as a critical input for permitting compliance with the US Army Corps of Engineers at the federal level, and the Oregon Department of State Lands at the state level.

The Company has engaged Native-X, Inc. ("Native-X"), a well-reputed, full-service archeological consulting firm that works extensively throughout Oregon, Nevada, and California. Native-X has commenced cultural and archeological baseline studies across the Project area to identify and document any historical properties or cultural resources that may be present. The results from these studies will support early engagement with relevant agencies and Tribal Nations, inform project design to avoid or mitigate potential impacts, and contribute to future permitting and environmental review processes.

The Company is in various stages of discussion with numerous other consultants regarding their engagement for additional environmental baseline studies, including but not limited to hydrology, hydrogeology, surface water quality, groundwater quality, flora and fauna, and geochemistry. Work on most, if not all, of these areas is expected to commence in advance of, or during, the PFS-related drill program this summer.

Aurora anchors Eagle's long-term strategy to develop an integrated nuclear energy platform combining domestic uranium resources with advanced SMR technology. As global demand for nuclear power accelerates and the U.S. looks to strengthen domestic fuel supply chains, the Company believes Aurora is positioned to become a strategic source of uranium for the next generation of nuclear energy.

About Eagle Nuclear Energy Corp.

Eagle Nuclear Energy Corp. is a next-generation nuclear energy company that combines domestic uranium exploration with exclusive Small Modular Reactor (SMR) technology. The Company owns the largest conventional, measured and indicated uranium deposit in the United States, located in southeastern Oregon. This includes the Aurora deposit, with 32.75Mlbs Indicated and 4.98Mlbs Inferred (SK-1300 TRS) of near-surface uranium resource, and the adjacent Cordex deposit, which the Company believes offers significant potential to expand the project's overall resource inventory. BBA USA Inc. previously completed Aurora's S-K 1300 Mineral Resource Estimate and authored the related Technical Report Summary in August 2025, providing technical continuity as the Project advances. By integrating advanced SMR technology with a sizeable uranium asset, Eagle is building an integrated nuclear platform positioned to help restore American leadership in the global nuclear industry.
