Mr. Wheatley continued: "Receipt of these FIRB approvals moves Snow Lake one step closer to building out our capabilities across the front end of the nuclear fuel cycle, with uranium assets in Wyoming and Colorado, an investment in Ubaryon (developing next generation uranium enrichment technology) and our investment in Kamos Energy Services (developing small light water reactors based on existing, proven designs, proven fuel technology and robust, established component supply chains).

Our development of U.S. focused capabilities across the nuclear fuel cycle directly aligns with and supports the U.S. Administration's policies underpinning the development of a domestic nuclear industry to enhance and ensure U.S. national, economic and energy security."

As announced by Ubaryon on May 5, 2025, Ubaryon agreed to form a strategic partnership with Urenco, a global uranium enrichment company. The agreement was reached after a comprehensive process involving a targeted group of potential investors and partners, conducted within the controls of the security legislation that Ubaryon's technology is regulated by.

Urenco Background

Urenco is an international supplier of enrichment services with sustainability at the core of its business. Operating in the nuclear fuel supply chain for 50 years, Urenco has its head office near London, UK, and enrichment facilities in Germany, the Netherlands, the UK and the U.S.¹

Urenco's deep technical, regulatory, market expertise, resources and strategic position in the nuclear fuel supply chain industry will make them the ideal strategic shareholder for Ubaryon moving forward.

Ubaryon Background

Ubaryon is a private Australian company which is developing and commercializing a unique uranium enrichment technology based on the chemical separation of naturally occurring uranium isotopes. The Australian Safeguards and Non-Proliferation Office, and Defense Export Controls, regulate all Ubaryon's technical disclosure. A significant feature of the Ubaryon enrichment technology is that it eliminates the need for conversion from uranium oxide or yellowcake (UO₄ or U₃O₈) to gaseous uranium (UF₆) and the need for deconversion from UF₆ to uranium oxide. Removing conversion and deconversion simplifies the enrichment process and allows for additional flexibility in the nuclear fuel supply chain.
