(d) The size ofarea(s) to be worked at any one time. <br />No further disturbances will occur onsite. <br />(e) An approximate timetable to describe the mining operation. The timetable is for <br />the purpose of establishing the relationship between mining and reclamation <br />during the different phases of a mining operation. <br />No further disturbances will occur onsite. <br />Timetable for Mining and Reclamation <br />No further disturbances will occur onsite. <br />(f) 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 />The bedrock depths in the proposed mine areas ranged from approximately 15 <br />feet to 19 feet below the 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 />Bestway Concrete & Aggregates — La Poudre Amendment- La Poudre Mine — MLRB 112 Permit Application <br />Exhibit D - 2 <br />
