Prince Albert Mine Plan of Operations Site Description <br />3.3 Future Mining Activity <br />Mining activity for the Prince Albert Mine under a 110(d) mining reclamation permit will be an <br />expansion of the bulk sampling operation performed under P- 2005 -21. This expansion of activity <br />will primarily focus on increasing the output of uranium and vanadium ore to a production level <br />between 5 and 75 tons per day, and continuing the surface exploration drilling program. The final <br />mine plan will be based upon an evaluation of the results from the bulk sampling plan. The mine may <br />eventually operate from one to two shifts per day seven days per week, with two to four employees <br />on each work shift, or six to eight people employed at the mine site during a five -day work week. <br />The mine may operate up to ten years if mineable reserves are expanded through further exploration <br />by surface and underground drilling. See Section 4 "Operation Descriptions" for more information <br />regarding the mining plan. <br />3.4 Geology <br />The Prince Albert ore deposit is typical of the local area, being situated in the Salt Wash Member of <br />the Morrison Formation at a depth of 100 to 600 feet below the surface elevation. The Salt Wash is <br />composed of fine- grained sandstone inter - bedded with mudstone. The target uranium and vanadium <br />ores are confined to beds that vary in both thickness and width. This type of deposit is generally <br />accessed through horizontal adits, decline or incline tunnels, and vertical shafts located in the canyon <br />walls or on top of local mesas. The area is dotted with historical examples of this method of mining. <br />See the Attachment 1 "Environmental Protection Plan" (which has been submitted as Exhibit U to the <br />DRMS Limited Impact 110(d) Permit filed on July 25, 2011) for a more detailed discussion of the <br />local geology. <br />3.5 Soil Characteristics <br />The areas of planned surface disturbance are defined as Bodot — dry, Ustic Torriorthents Complex <br />(Soil Map Unit 23) as mapped by the Natural Resource Conservation Service (NRCS, 2007 - 2010). <br />This soil type is slightly alkaline and occurs on slopes ranging from 5 to 50 percent. The soils in the <br />northern section of the affected area are made up of thin, isolated, and discontinuous pockets of <br />weathered sandstone, mudstone, and shale mixed with accumulated organic matter and vegetative <br />debris, such as pine and juniper needles, from plants growing on the slopes. These soil pockets range <br />in thickness from zero to six inches, at most. Soil is very discontinuous in the northern part of the <br />affected area and the recovery of soil for post- mining growth medium will be limited to an average <br />depth of two inches. The southern portion of the affected area has locations with a deeper soil horizon <br />and an estimated recoverable soil depth of four to eight inches after it is amended with mulched <br />Rimrock Exploration and Development Page 5 of 27 <br />
