Liberty Mining, LLC <br />DRMS 110 -d Permit Application <br />October 2013 <br />radioactivity is slightly higher in the vicinity of the Liberty Mine site because it is a previously <br />mined and reclaimed site from the late 1970's and early 1980's. <br />Historical mining in the Uravan Mineral Belt has demonstrated that acid mine drainage is not <br />likely because minerals commonly associated with uranium deposits lack sulfides necessary to <br />produce acidic leaching. Pyrite (FeS2) does have the potential to occur with uranium deposits <br />as it is related to a chemical reduced environment. The amount of pyrite is expected to be <br />minimal and therefore will have minimal leaching potential. Furthermore, the Salt Wash <br />sandstone formation in which the majority of the mining activity will occur is a calcareous <br />formation consisting of calcium deposits that will contribute alkali characteristics to percolated <br />water that may come in contact with extracted materials. Thus, the waste rock stockpile will <br />have little potential to generate acid mine drainage. <br />A background gamma radiation study was conducted at the Liberty Mine site in October, 2012 <br />using a calibrated Ludlum Model 3 Survey Meter with a 44 -9 Pancake Probe. The study <br />indicated the surface area of the Liberty Mine site contains naturally occurring or previously <br />exposed radiation concentrations between 120 to 480 counts per minute. Radiation counts <br />taken during exploration drilling found concentrations of 80 to 100 counts per minute at the <br />surface and a maximum of 1,400 counts per minute in the ore zone. <br />During mining operations there will be no processing of uranium or vanadium ore on site. All <br />ore will be removed from the underground mine and stored on the concrete ore stockpile pad <br />until a highway transport truck is available for shipment to the offsite milling facility. No material <br />will be brought from the processing mill to the mine site for disposal. <br />U (6.a-c) Designated Chemical and Material Handling <br />Uranium and vanadium is the material of most concern at the Liberty Mine site. Uranium is <br />radioactive and possesses the potential to adversely affect human health and the environment. <br />During operations, uranium ore is to be handled in accordance with the mining plan, Exhibit C. <br />The ore will be handled minimally to achieve the objectives of the mining plan, reduce <br />environmental impacts of the mining operations, and maximize the quantity of marketable ore. <br />The ore will be extracted from the mine and placed in the ore storage pad where it will remain <br />until it is loaded for transportation to the processing mill. The ore will not be processed on site <br />and no ore process tailings will be on site. The ore storage pad will be located near the center <br />of the mine operations pad to reduce the potential for offsite migration of uranium materials. <br />The central location of the ore storage pad will also decrease the surface distance the ore <br />travels between the mine portal and the ore storage area. The stormwater collection and <br />drainage design for the ore stockpile will feature a designated lined stormwater collection sump. <br />Mine workers will be trained in the hazards of radiation exposure through mandatory Mine <br />Safety and Health Administration (MSHA) training and Hazard Communication (HazCom) <br />programs. All mine workers, visitors and contractors are to have MSHA safety training and <br />radiation exposure training. All those who regularly visit or work at the mine will have medical <br />surveillance to track occupational radiation exposure rates. <br />Liberty Mining, LLC Moab, Utah SMA Ref. 5821897 Page 54 <br />
