Project Description:
Energy Fuels is proposing to modify its Daneros Mine Plan of Operations. The proposed modification would expand facilities at the Daneros Portal Area; add new facilities at two historic mine sites (the Bullseye and South Portal Areas); and construct additional vent holes and associated access roads to support future mining. The proposed facilities include the folowing: rehabilitation of the existing Bullseye Portal; Construction of the South Portal; expansion of the development rock area (DRA) at the Daneros Portal Area; construction of DRAs at the Bullseye and South Portal Areas; construction of ore stockpile areas at the Bullseye and South Portal Areas; construction of topsoil and inert material stockpile areas; installation of drainage control structures; installation of mine infrastructure systems; installation of office/shop complex at the South Portal Area; and installation of up to 8 additional ventilation holes. Operation and maintenance of these facilities would occur throughout the life of mine (20 years). The facilities would be constructed in a phased manner with mine operations resuming at the Daneros Portal and construction starting at the Bullseye Portal. As mining progresses, the South Portal Area would be developed while much of the the Daneros and Bullseye Portal Areas would be reclaimed, including the DRAs. All disturbed areas would be reclaimed at the conclusion of mining operations. Total ore production for life of mine would increase from 100,000 tons over 7 years to 500,000 tons over 20 years. Total mine disturbance would increase from 4.5 acres to 46 acres.
Project Location:
The Daneros Mine is located in Bullseye Canyon, in the central portion of the Colorado Plateau in southeast Utah. The mine is remotely located approximately 67 miles west of Blanding, Utah in T. 37 S., R. 16 E., Sections 5, 6, 7, 8, 17 and 18, San Juan County.
