enCore Energy Completes 1,600 gpm ISR Plant Phase, Targets 3,200 gpm by July
EU•enCore Energy completed construction of its Upper Spring Creek ISR Satellite IX Plant’s first phase, installing a 1,600 gpm ion-exchange flow capacity. The plant’s capacity will double to 3,200 gpm by end of July, and first production wellfield nearing completion will enable uranium extraction once final permits are secured.
1. First Phase Construction Completed
enCore Energy has finished the first phase of its Upper Spring Creek ISR Satellite IX Plant, marking its largest satellite facility to date with a 1,600 gpm ion-exchange flow capacity ready for uranium-loaded resin production.
2. Capacity Expansion Timeline
The facility’s flow capacity is set to expand to 75% by the end of June and reach 100% (3,200 gpm) by the end of July, pending receipt of final operational permits before commencing uranium extraction.
3. Wellfield and Extraction Readiness
Drilling for the initial 800 gpm wellfield module is complete and infrastructure is nearly finished, while drilling for three additional 800 gpm modules is underway, with module two at 90% completion, positioning the project for immediate feed to the IX Plant.
4. Strategic Integration with Rosita CPP
Once operational, the Satellite IX Plant will supply uranium-loaded resin to enCore’s fully licensed Rosita Central Processing Plant for yellowcake production, enhancing the company’s capacity to meet U.S. nuclear fuel demand.
