EXHIBIT D - Mining Plan <br /> a) Mining will utilize the following operations: <br /> i)Use of dozer to remove and stockpile existing top soil <br /> ii)Utilize dozer to remove and stockpile overburden <br /> iii)Utilize dozer to push up gravel <br /> iv)Utilize a frontend loader or track hoe to load material onto trucks. <br /> b) The site will be mined to approximately 20 feet in depth. Mining will be done on an <br /> approximate 3:1 slope down to the bottom of the pit area. There is no topsoil in the <br /> actual dry creekbed itself. Topsoil outside the creek bed ranges from 4"-5" in depth. <br /> The area lying outside the creek bed will have the topsoil stripped, stockpiled for re- <br /> application during reclamation. The bank along the creek will also be stripped and <br /> stockpiled for later use in reclamation. Any topsoil stockpile will be seeded with <br /> brome grass to prevent soil erosion. <br /> c) There are no anticipated water diversions or impoundments. There is no surface <br /> water at the site. When rainfall occurs, the pit area may be unworkable for a few <br /> days. Since the use of the pit is intermittent, we will be able to work around those <br /> occurrences. <br /> d) Our intent is to work only a few acres as we move east each time. In each move new <br /> delineator posts will be set. The permanent NE and SE corners will not be set until <br /> mining efforts finally reach the east end. The unused portion of the pit will continue <br /> to be farmed until we are ready to move into that area. We plan to maintain a 25-foot <br /> setback around the entire perimeter of the pit for maintenance and inspection. Thus, <br /> only 31.4 acres will actually be disturbed. The boundary line and corners will be <br /> clearly staked with red painted steel posts <br /> e) The mining plan is to begin in the existing pit-current production. We will remove <br /> top soil by dozer and create a stockpile on the north side of this 9.9-acre area. The <br /> top soil on the west edge appears to be about 3-6" deep, while top soil along the east <br /> side is almost non-existent. Stockpiles of top soil will be seeded with brome grass to <br /> minimize blowing or erosion. When the current area is mined,the top soil will be <br /> spread out evenly and the 3:1 slope maintained on the sidewalls. The next area to be <br /> mined will be to the east of the existing pit. <br /> No on-site processing is anticipated. <br /> i) Since the pit will be used on an intermittent basis, it is difficult to estimate the <br /> time it will take to mine all three areas. We are estimating that it will take ten <br /> years to mine the expanded pit. <br /> 3 <br />
