Description:
The Dewey Burdock In-Situ Recovery (ISR) Uranium Project is a proposed uranium production facility located in Fall River and Custer Counties, South Dakota. The project will recover uranium from subsurface sandstone ore bodies through ISR technology, which involves the injection of a lixiviant solution into production wellfields to dissolve uranium minerals in place and pump the uranium-bearing solution to a central processing plant for recovery. The use of ISR technology allows for minimal surface disturbance compared to conventional open-pit or underground uranium mining. The project consists of wellfield areas, a central processing plant, supporting infrastructure and environmental protection systems. The project has been licensed by the NRC (Source Material License SUA-1600) and is progressing toward final state and federal authorizations required to begin commercial production.
