The Lost Creek East amendment would increase the areal extent of mining in the HJ Horizon and vertically expand mining into the next deeper mineralized sandstone, the KM Horizon, within the existing Lost Creek ISR Project area. The amendment would also expand uranium ISR into an area east of and contiguous with the existing Lost Creek ISR Project area, referred to as the LCE expansion area. Both the KM and HJ horizons would be mined within the LCE expansion area. The LCE expansion area would add approximately 5,751 acres to the existing Lost Creek ISR Project area of approximately 4,254 acres for a combined project area of 10,005 acres. The amendment would add up to 1,415 acres of surface disturbance within the project area (existing Lost Creek ISR Project area and proposed LCE expansion area) over the life of the project. Lastly, the amendment would increase the authorized annual yellowcake production rate to 2.2 million pounds per year. LCI is currently authorized by NRC to produce up to 2 million pounds of yellowcake per year. The BLM is working on an EIS for the Lost Creek East project.
