| About the Upper Spring Creek ISR Project
The 100% Company-owned Project consists of a Satellite IX Plant and wellfield and is a key component of enCore’s larger South Texas Uranium Project. This satellite facility will operate in conjunction with multiple future potential production units within the historic Clay West uranium district.
The Project was previously held by Signal Equities LLC, which licensed and permitted the property as an ISR uranium project. Key elements of their permit were maintained, including the aquifer exemption. Their work ceased following continued low uranium spot prices. In December 2020, the Company acquired the Project.
The uranium-mineralized sands associated with the Project area lie within the Oakville Formation. These historic uranium-producing sands stretch across an area of approximately 120 miles long by approximately 20 miles wide in South Texas. The saturated uranium-mineralized ore body at the Project typically occurs at depths between 300 and 450 feet below the surface, allowing for efficient and economical uranium recovery with ISR methods.
Satellite Ion Exchange Process
A Satellite IX Plant uses ion-exchange technology that begins with injecting a lixiviant, consisting of groundwater mixed with oxygen, into the wellfield, where it dissolves uranium from underground sandstone. The uranium-bearing water is then pumped to the surface and cycled through the nearby Satellite IX Plant, where uranium is absorbed onto resin beads. The IX resin is then transported to enCore’s Rosita CPP, where the uranium is stripped from the resin, and the stripped resin is returned and reused. The water is refortified with oxygen and recycled back into the formation. This 50-year-old process is closely monitored and has been verified by the Texas Commission on Environmental Quality. For more than five decades, it has been proven to be environmentally safe and very efficient to operate.
enCore’s Satellite IX Plants are located near wellfields and are a key component of the ISR uranium extraction process. These modular, efficient IX Plants have a short installation time, enable cost-effective operation across multiple sites without constructing full CPP facilities at each site, and can be relocated to support additional uranium recovery.
Rosita ISR Uranium Central Processing Plant and USC Satellite Plant
The Rosita CPP receives uranium-loaded resin transported from enCore’s South Texas Satellite IX Plants. The CPP removes the uranium from the resin and processes it into yellowcake. Once processed, the resin is recycled and transported back to the Satellite IX Plants for reuse.
