(� Use Mining Plan Map in conjunction with narrative to present: <br /> (i.) Nature, depth and thickness of the deposit and thickness and type of <br /> overburden to be removed <br /> Exploratory borings were performed by Bestway Concrete. The bedrock depths in <br /> the proposed mine areas ranged from approximately 20 feet to 30 feet below the <br /> ground surface. <br /> (ii.) Nature of the stratum immediately beneath the material to be mined in <br /> sedimentary deposits <br /> The site is located approximately 15 miles east of the foothills of the Colorado <br /> Front Range on the western flank of the Denver Structural Basin. The basin is a <br /> downwarp of sedimentary strata that tends north-northwest, parallel to the <br /> mountain front. In the project area, the sedimentary bed dips gently eastward <br /> toward the axis of the basin east of the site. Based on regional geologic mapping <br /> (Colton, 1978), the near surface bedrock in the project area is the Paleocene and <br /> Upper Cretaceous Denver and Arapahoe Formations. The bedrock is overlain by <br /> upper Pleistocene and Holocene (Quarternary age) gravel deposits and eolian <br /> (wind blown) overburden soils. The gravel deposits exist primarily within the <br /> Broadway Alluvium deposit. The bedrock unit consists mainly of claystone and <br /> may contain lenses of siltstone and sandstone. <br /> (g) Identify the primary and secondary commodities to be mined/extracted and <br /> describe the intended use. <br /> The primary commodities are sand, gravel and fill; intended for construction materials. <br /> (h) Name and describe the intended use of all expected incidental products to be <br /> mined/extracted by the proposed operation. <br /> There are no expected incidental products to be mined. <br /> (i) Specify if explosives will be used in conjunction with the mining(or reclamation) <br /> No explosive material will be used on-site. <br /> Bestway Concrete&Aggregates—Vogl Amendment-Shores Mine—MLRB 112 Permit Application <br /> Exhibit D-3 <br />
