<br />EXHIBIT D <br />Mining Plan <br />The Baseline Resource Property has a significant commercial deposit of sand and gravel located <br />in the alluvium of the South Platte River in Weld County. There aze 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 />Before any mining commences, the operator will install a slurry wall azound the mining area. <br />The slurry wall will sepazate the mine from the adjacent aquifer and prevent ground water <br />depression. <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 inches in depth and will be <br />stockpiled separately. The overburden consists of clayey sand and silty sand and it will also be <br />stockpiled separately. Later these stockpiles will be used in reclaiming and sloping the <br />lakeshore. With in-progress reclamation, it is the intent of the operator to replace the overburden <br />and topsoil in its final location quickly. As mining progresses, the operator will replace the <br />topsoil and spread it on the Lakeshore slopes immediately after it is stripped from a new mining <br />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 area 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 Vansport the material to the <br />aggregate processing area. <br />The subsurface drilling of the site indicates that the deepest deposits aze in the east section and <br />may be up to 45 feet in depth. The shallowest deposits aze to the west and aze 30 to 35 feet deep. <br />The mining will create one lake. <br />The first azea to be dug will be a small pit established as a settling pond for the sand and rock <br />washing operation. <br />The mining will then proceed to the Phase 1 area on the north side of the property. Mining will <br />progress southward into the Phase 2 and 3 azeas. Lastly the processing area will be mined. As <br />this Phase 4 azea is reduced in size, equipment will be moved off site. <br />Each yeaz approximately two to five acres of land will be mined. Annual production will depend <br />directly upon the demand for construction materials in the northern metro azea of Denver. The <br />anticipated production is from 200,000 tons to 400,000 tons per year. This production will also <br />vary depending on the amount of outside sales as related to internal production of concrete and <br />asphalt. <br />D-1 <br />
