As shown on the map, the natural drainage is from upslope is away from the pit and this <br />configuration will be maintained. The only water will be the result of limited precipitation. The <br />overburden stockpile will effectively prevent any run-on of precipitation from upslope. A berm <br />will be constructed to direct any potential run-off from the ore pile to the floor of the former <br />Monogram Pit which is in effect a sediment pond constructed in the low lying area with a 3 ft <br />high berm maintained at the west end above the area of pre-existing waste rock (see Map C-2). <br />As each section of ore is removed, the adjacent barren cap rock will be placed in the excavated <br />area and restoration will be concurrent with mining. Surface drainage of the mine will continue <br />to be toward the eastern berm and that berm will be raised and/or extended to maintain function <br />for water retention and as a silt trap. When all the surface ore is removed, the waste rock will be <br />graded across the disturbed area to match natural contours and a grade of less than 3:1. The <br />minimal stored topsoil will be spread and re-vegetated. <br />3. Exploration <br />The second phase of operations for the permit will be exploratory in nature. Nuvemco will <br />explore old mines and workings in the area. Many of these old mines utilized tracks and ore <br />carts for removing ore and muck, often focused only on mining the highest grades of ore. Others <br />were small one- or two-man operations that removed only very high grade ore such as fossil logs <br />that were replaced by uraninite (pitchblende). Most mining operations stopped when the mills <br />shut down, potentially leaving significant uranium and vanadium resources in the ground. <br />Concurrent with the evaluation of old workings exploration boreholes will be drilled on existing <br />roads and trails throughout the permit area to evaluate subsurface ore potential. Based upon the <br />results of these exploration efforts, the Monogram Mine permit may be amended to include any <br />additional surface or underground mining plans. <br />4. Surface Facilities <br />As illustrated on Map C-1, surface facilities on the permit will be modified shipping containers <br />(C-Cans). One will be used to store supplies, ATVs, equipment, and the other as office trailer. <br />The facilities may be expanded if the exploration efforts are successful and a technical revision <br />of the permit will be prepared and submitted at that time. Parallel to and slightly south of the <br />southern permit boundary is a power line owned by San Miguel Power Association which <br />supplies electricity to the top of the Monogram Mesa including previous, planned, and existing <br />mines in the area. A power supply may be brought in from the power line to a drop pole erected <br />at the office. There are no other utilities within 200 feet of the permit boundaries. A portable <br />toilet facility will be located near the office trailer. <br />The C-Cans are located on a barren flat spot; about 200 ft by 250 ft, in the northwestern part of <br />the proposed permit area. A concrete pad with ore bins will be constructed on the south side of <br />the staging area for ore stockpiles and grade control. (See Photograph 6 for location and Map C- <br />1 for drawing of bins to be constructed) The surface facilities on the Monogram Mine 112d <br />Permit area will include the following: <br />• overburden stockpile <br />• two C-Cans modified for storage and office use <br />Monogram Mine - November 2008 <br />D-3
