UEC restarted operations at the Christensen Ranch ISR operation in Wyoming in August 2024. The S-K 1300 Technical Report Summary disclosing resources for Wyoming Hub and Spoke ISR Platform was filed on September 15, 2022, marking the largest S-K 1300 uranium resources reported in the United States.
The Irigaray Central Processing Plant is the Hub central to eleven satellite In-Situ Recovery (ISR) projects across the Powder River Basin (“PRB”), with 10 Project areas (Spokes) as shown below.

Uranium Energy Corp Completes Acquisition of Rio Tinto's Sweetwater Plant and Wyoming Uranium Assets
In December 2024, UEC completed the acquisition of 100% of Rio Tinto's Wyoming assets, comprised of the wholly-owned and fully-licensed Sweetwater Plant and a portfolio of uranium mining properties, including the Red Desert Project and the Green Mountain Project, with approximately 175 million pounds of historic resources. This creates the second Hub and Spoke platform in Wyoming, with both ISR and conventional uranium resources.
In the Great Divide Basin of Wyoming, the combination of the recently acquired Sweetwater Plant and portfolio of 8 permitted and exploration stage projects and UEC’s existing 12 ISR projects enables UEC to create a second Wyoming Hub-and-Spoke production platform with a total of 20 potential spokes, shown below.
