Background <br />Exhibit D <br />Mining Plan <br />JD -9 Mine Permit Amendment <br />M- 1977 -306 <br />The JD -9 Mine was permitted by the DRMS in 1977on the JD -9 lease from the DOE. <br />The mine originally consisted of two permitted areas: one along the south slope of <br />Monogram Mesa in Bull Canyon and the other a treatment pond area on top of the mesa, <br />totaling 8.25 acres. Cotter later amended the permit to include a total of 11.10 acres. <br />The JD -9 mine site after this amendment will include 26.77 acres divided into two <br />separate areas. On top of Monogram Mesa are 9.1 acres of permitted area encompassing <br />the water treatment facility, treated water ponds, and the mine ventilation shafts. This <br />area is called the Upper Mine Area. South of this area, and significantly lower in <br />elevation, is the primary permitted area of 16.5 acres along the mesa slope in Bull <br />Canyon. This area contains the mine portal, shop, equipment storage, parking, ore pad, <br />and waste pile. This area is called the Lower Mine Area. Two ventholes in the upper <br />mining area have a total acreage of 1.17. <br />The ore deposit is located in the Salt Wash Member of the Morrison Formation which <br />consists of interbedded fine -grain sandstone and mudstone. The ore is located within the <br />upper (i.e., Top Rim) sandstone of the Salt Wash and occurs in areas of reduced gray <br />sandstone and where the sandstone is in contact with gray or green mudstone bands. The <br />uranium and vanadium mineralization occurs in bands that range in thickness from a few <br />inches to in excess of eight feet. The average ore thickness is 2.7 to 3.0 feet. The ore <br />body is located below approximately 650 to 750 feet of cover and can be accessed <br />through an adit located on the side of canyon walls and ventilation shafts. (For a full <br />description of the area geology, see Exhibit U — EPP.) <br />The uranium and vanadium bearing ore will be sent to a mill to be separated into <br />concentrates of U and V2O <br />Timeline <br />The majority of the planned construction is already completed at this site. Additional <br />acreage will be involved as the waste dump grows or additional roads for ventholes and <br />development drilling are needed. This land has been accounted for in the affected <br />acreage. <br />The area that may be classified as a major disturbance is the waste storage area. Areas of <br />moderate disturbances include the treatment ponds, the area required for stabilization of <br />the waste area and graded areas used for parking, structures, and equipment storage. <br />D -1 <br />
