Gunnison, Colorado. MINED LANDRECLAMATIDND141SIDN Colo. Dept. of Natural Resources Exhibit A - Legal Description The area to be permitted is 9.9 acres in the NW% of the NE4 of Section 24-T49N-R2W of NMPM, in Gunnison County, Colorado, as shown on the maps identified as Exhibits C-1 and C-2. The designdted area begins approximately 300 "west and 600' south of the respective east and north boundaries of the 40 acre tract as detailed in the Plot Map, Exhibit C-3. Exhibit B - Minim Plan Access to the area is from U.S. Highway 50, five miles west of the town of Gunnison. The. entrance is coritroled by a locked gate used by both the operator and the federal government. Thus, only a small portion of the haul road ( 0,14 acres ) is used solely by the mine operator. The east approach to the mining area is confined by gran- ite walls to the left and right. The entrance to the area is about 100' wide and broadens out into a mined-out bench t]~at is approximately 288' wide and 240' deep (about 1.6 acres). The first bench is used for the crusher oper- ation, material stockpiles, and vehicle turn-around. The present mining face is located on a 2nd bench which is about 15' above tl~e 1st: It is the operators intention to proceed with mining in a westerly direction up the slope in a series of 15 - ZO' benches. Due to the steep- ness of the slope, the 2nd bench may be too narrow to accomodate the crusher. Therefore, material will be moved by a conveyor system doM~ to the 1st bench until adequate space is created on the 3rd bench. ~ The overb~~rden approaches the the overburden of the exposed the permitted twice as wide ~ ,, ". . is estimated to be 30' deep as the mining ;~!--"r. hilltop in the 3rd phase. Of necessit}~, r,--; _ ~ i has been stockpiled to the left. and right working face. Consequently, the width of area adjacent to the 3rd bench is aimost as the working face of the mine. The present disturbed area encompasses 2,4 acres of the proposed 9.9 acre site. The remainder of the acreage is found in an almost square area identified on the Plot Map as phases 4 a1~d 5. The permitted boundaries will widen from 300' in phase 3, to 575' on the hilltop at a point that is 615' from the west boundary of the 40 acre tract.
