EXHIBIT D Mining Plan <br /> a) The mining is currently taking place within the existing 110 permit boundaries. That <br /> area will be expanded as soon as possible after a permit is obtained. The operation will <br /> provide material for road operations. The pit will continue to operate annually. The <br /> supply is undetermined, but it is expected to last indefinitely because of the limited use <br /> of the pit. This should be classified as an intermediate pit. <br /> b) The pit boundaries are much larger than the anticipated area to be mined. This will give <br /> the county latitude in where stockpiles can be placed. <br /> c) The mining plan is to continue removal of sand and gravel within the confines of the <br /> banks of the creek bed beginning at the east edge of the pit area (200'west of the <br /> property line) and proceeding west within the banks of the creek until the creek hits a <br /> point 200' east of the west property line of the SW%of Section 2,T7N, R45W. Mining <br /> close to the west and east ends will stay back 200' from the roadway and the adjoining <br /> property owner. Mining on each end of the pit will be sloped 7:1 to avoid erosion when <br /> flood waters enter or exit the pit area. Excavation will continue as the need for gravel <br /> continues for local road operations and, as the supply remains available. There is <br /> currently no topsoil in the creek bed itself. There is topsoil in the areas outside the <br /> creek bed which is 4-5" in depth. Any disturbed banks along the creek will be stripped <br /> and stockpiled for later use in re-vegetation. Any topsoil stockpile will be seeded with <br /> brome grass to prevent soil erosion. There would appear to be no waste rock or <br /> material at the site. <br /> d) Mining is anticipated to a depth of 20' inside the creek bed. The mining began at the <br /> east end of the pit and proceed west. No slopes will be left greater than 3:1. <br /> e) Access is available off County Road 24. A short access trail runs from Co. Rd. 24 north to <br /> the creek. As mining moves to the west edge of the pit, access will be directly onto Co. <br /> Rd. 33 at the southwest corner of the property. There will be no shop, plant, or other <br /> facilities located at the mine site. The equipment used to mine the gravel will be a <br /> front-end loader, dozer, and trucks. There will be stockpiling of material at the site. <br /> Stockpiles will be placed in line with the drainage flow line that runs through the area <br /> and along the edges of the pit. The anticipated stockpile areas are shown on the mining <br /> plan. No processing of material is anticipated at the site. <br /> f) There are no existing disturbances to describe at the site. <br /> g) There will be direct access from the pit onto county roads. No new roads will be <br /> required. <br /> h) No water is anticipated in conjunction with the operation. Groundwater is well below <br /> the anticipated depth of mining. We will commit to keeping all mining efforts at least <br /> Haynes Hereford Ranch Pit Page 3 <br />
