Sheep Mountain Project

Wyoming, United States · Underground

Care And Maintenance
Uranium
Mine life
12 years
Workforce
At full production, the project is expected to require approximately 200 employees. Around 80 of these employees will be for the open-pit, heap leach, and processing plant operations, with the remainder required for the underground mine.
Overview
The Sheep Mountain Project is currently on standby. The project is fully permitted for mining, but the company is evaluating ore processing options. A planned on-site heap leach facility has not yet been permitted, and the company is considering this or processing at a third-party facility, pending improved market conditions.
Production
The project is expected to produce 1.4 million pounds of uranium annually. A separate source states a peak production rate of 1.5 million pounds of U3O8 per year.
Processing
The proposed processing method is a conventional heap leach process. The run-of-the-mine ore will be crushed and placed on a heap pad. An acid leach solution will be applied, and the resulting pregnant leach solution will be processed in a solvent extraction plant to produce yellowcake.
Equipment
Open-Pit Mining: The planned equipment for the Congo pit includes four 637 CAT twin-engine scrapers, four 631 CAT single-engine scrapers, two medium-size excavators, two motor graders, two track-dozers, two 32-tonne articulated trucks, one 980 CAT wheel loader, and two water trucks. Underground Mining: The underground operation is planned to utilise five jumbo drills, nine bolters, and six scooptrams with a seven-cubic-yard capacity each. A 36-inch conveyor system will be used for ore haulage.
