<br />EXHIBIT D <br />Mining Plan <br />The Firestien Property has a significant commercial deposit of sand and gravel located in the <br />alluvium of the Cache La Poudre River in Weld County. There are existing mining operations <br />immediately to the south of this property. The west, north, and east sides of the property are in <br />agricultural uses. <br />The deposit will be mined dry through the use of dewatering trenches and pumps. Initially the <br />topsoil and overburden will be stripped by scrapers. The topsoil is 6 to 12 inches in depth and <br />will be stockpiled separately. Some areas of the deposit do have overburden consisting of clayey <br />sand and silty sand. If this is encountered, it will also be stockpiled separately. Later these <br />stockpiles will be used in reclaiming and sloping the lakeshore. With in-progress reclamation, it <br />is the intent of the operator to replace the overburden and topsoil in its final location quickly. As <br />mining progresses, the operator will replace the topsoil and spread it on the lakeshore slopes <br />immediately afrer it is stripped from a new mining area. <br />With the stripping done, the dewatering trenches will be dug down to the bedrock. These <br />trenches will be constructed on the east, north, and west sides of the azea to be mined. Direction <br />of mining is generally to the south. When the alluvium is sufficiently dry, front end loaders will <br />excavate the material and deposit it in haul trucks which will transport the material to the <br />aggregate processing area. <br />The subsurface drilling of the site indicates that the deepest deposits are in the north section and <br />may be up to 25 feet in depth. The shallowest deposits are nearest the river and are about ten feet <br />deep. The mining will create two lakes. The largest lake is in the central portion of the property <br />and the small lake is located within the oxbow on the west side of the property. <br />Parts of the farm not yet disturbed b}' mining will continue in farming and grazing. The ditch <br />lateral system can be maintained so these areas can be irrigated. <br />The first area to be dug will be the Phase 1 mining area at the east end of the property. It will be <br />a small pit established as a settling pond for the sand and rock washing operation. In addition, <br />excess overburden can be deposited in this hole. <br />The mining will then proceed to the Phase 2 azea on the north side of the property. Mining will <br />progress southward to the terrain break of the land which is at the edge of the 100 year <br />floodplain. Mining will then proceed to Phase 3 which is within the oxbow on the west side. <br />The mining will then return to the central portion of the property in Phase 4. <br />D-1 <br />
