Response to DRMS Adcp acy Review - Cotter JD-8 Mine Reclamation Plan Amendment <br /> anticipated to last for approximately six years of production and development activities. <br /> 41110 The lower mine waste area encompasses twelve acres of affected area. <br /> It is anticipated that portions of the lower mine waste area will have reclamation started <br /> following six years of production and development activities. Once the ore storage pad <br /> and personnel access to the mine is no longer required building demolition and final re- <br /> contouring and seeding will be done. This is anticipated to take less than twelve months. <br /> The vent holes will be closed and the areas seeded within a few months after production <br /> activities have been completed and it is determined they are no longer required. <br /> The main ore deposit is located in the Salt Wash Member of the Morrison Formation, <br /> which consists of interbedded fine-grained sandstone and mudstone. The uranium and <br /> vanadium mineralization occurs in bands that range in thickness from a few inches to <br /> more than six feet. The average ore thickness is from 2.5 to 3.5 feet. The ore body is <br /> located from 500 to 700 feet below the top of Monogram Mesa. <br /> Uranium and/or Vanadium mineralized rock are the primary products that will be mined <br /> at the JD-8 Mine. At this point in time there are no other expected incidental products <br /> that will be produced at this mine. <br /> Explosives have been used at this mine to advance mine workings, and are a planned part <br /> of the ongoing mining process here. <br /> During the operation of the mine less than 1,320 gallons of fuel and oils will be stored on <br /> the property. The fuel tank will be located within a bermed and lined catchment. The <br /> oils stored on the surface will be located within a bermed and lined catchment. <br /> 1111 <br /> Page A-13 <br />
