Liberty Mining, LLC <br />DRMS 110 -d Permit Application <br />October 2013 <br />on Hwy 191 and travel south 6.7 miles to Black Mesa Road where the White Mesa Mill is <br />located. <br />The ore will be loaded and transported by contract over - the -road, combination tandem axle <br />semi - trailer and single axle pup trucks in compliance with all USDOT, Colorado DOT and Utah <br />DOT Hazardous Materials regulations. The transportation contractor will have an active <br />emergency response plan for accidents and spills. In the event of an accident or spill, all <br />associated agencies will be notified. <br />Ore Storage Pad Reclamation <br />The ore pad is an engineered, concrete reinforced pad with external reinforced corners to <br />prevent damage. During reclamation, the ore pad will be cleared of all debris and all soils will <br />be returned to the underground workings. The concrete floor and walls will be pressure washed <br />and wash water will be contained in the ore pad sump. The concrete structure will be <br />demolished and transported to the underground mine or hauled off site, contingent on available <br />space in the mine. The water in the sump will be pumped into the mine decline and the <br />remaining sediment will be hauled to the mill for processing. The ore pad pond liner will also be <br />pressure washed until gamma radiation monitoring indicates that the radiation level is below the <br />background gamma readings. The pond liner will be removed and placed in a dry section in the <br />underground mine. The ore pad and sump will then be backfilled to the surrounding grade with <br />waste rock material and stabilized with a growth medium layer. The surface will be scarified <br />and seeded in accordance with the reclamation plan. <br />Waste Rock Stockpile <br />The waste rock will be removed from the underground mining operations and stored in a <br />stockpile on the surface mining operations pad. Close attention will be made during the waste <br />rock removal and segregation to minimize the spread of uranium and vanadium ore. The waste <br />rock pad will be located to the north of the mining operations pad. The size of the waste rock <br />pile may gradually increase in size as operations progress as not to exceed a 3:1 slope within <br />the'boundary of the mining operations pad. Dependent on the need for a large waste rock <br />stockpile, topsoil and vegetation will be stripped and stockpiled in sections, to reduce surface <br />disturbance, but with adequate distance to prevent spill -over of waste rock into the topsoil <br />stockpile. The stormwater management plan will adapt to the increasing footprint with <br />expansion of erosion control of the topsoil and waste rock stockpiles, as needed. <br />Waste Rock Reclamation <br />The majority of the waste rock stockpile will be returned to the underground mine as the work <br />progresses and rooms are made available. A portion of the waste rock stockpile will be used for <br />backfill of the removed ore pad and sump pond site, and to backfill the mine portals and <br />declines. The remaining waste rock stockpile will be graded and contoured to match the <br />surrounding terrain and to correct slopes that may have exceeded a 3:1 slope during mining <br />operations. The graded waste rock will be stabilized, scarified, covered with growth medium, <br />and seeded in accordance with the reclamation plan. <br />Liberty Mining, LLC Moab. Utah SMA Ref. 5821897 Page 57 <br />
