EXHIBIT D <br /> MINING PLAN <br /> Amendment Area A is the area to be mined. This area is along the Cache LaPoudre <br /> River east of 21 st Avenue, north of the Colorado and Southern Railroad, and west of the <br /> City of Greeley Island Grove Park. The total area to be mined is approximately 30 acres. <br /> Amendment Area B will be used as a temporary location for the portable processing plant <br /> while the mining is being completed in the current permit area. Area B will be used for <br /> some stockpiling. This area is approximately 24 acres. <br /> The proposed mining method will be done as a dry mining operation. The existing mining <br /> area has operated as a dry mining operation for the past 10 years. A dewatering trench <br /> will be constructed around the perimeter of the mining area by phases and water will be <br /> removed by pump to an adjacent pond for settling and percolation into the alluvium. The <br /> location of the pond is shown on Exhibit C. <br /> The deposit to be mined is the valley fill deposit along the Cache La Poudre River. This <br /> deposit consists of sands and gravels with interspersed layers of silt and clay lenses. <br /> The deposit is relatively well graded and has aggregates as large as 12 inches and many <br /> fines passing the 200 micron sieve. The material will mainly be used as a pit run product. <br /> This means there is little crushing or washing done and it is excavated and hauled directly <br /> from the site. Occasionally some of the material will be washed and crushed. <br /> Approximately 5% of this material becomes reject or waste and is used for backfilling in <br /> reclamation. <br /> The area will be mined in two phases using scrapers and front-end loaders. We expect <br /> the mining to last for twenty (20) years. <br /> Phase 1 will start on the northeast side of the property and move to the southeast. <br /> Material in the lowlands area along the Poudre River and the City of Greeley Island Grove <br /> Pond will be removed and cleaned up first. This area was disturbed by other operators <br /> prior to the mining laws. Approximately 8.53 acres will be disturbed in Phase 1. During <br /> the initial phase of the ruining, there will be very little topsoil to be removed. All <br /> overburden and topsoil was removed by previous mining operators. <br /> The portable processing plant will be moved into area A during the mining of Phase 1. <br /> This plant will be located at the site of the Old Farmhouse. (The farmhouse was given <br /> to the Western Hills Fire Protection District and was recently burned for training and <br /> practice.) <br /> D-1 <br />
