Phase I -includes the original 110 permit area, and includes 19.65 A. Mining will proceed both <br />north and south from that area. Phase I will be entirely major disturbance. <br />Phase II -lies immediately south of Phase I and contains some of the thickest aggregate on the <br />subject property. Mining will proceed from north to south, with topsoil being stockpiled on the <br />east and west pit perimeters. <br />Phase III -lies in the southeast corner of the pit area immediately south of the Colorado <br />interstate Gas Co. - CF&I Lateral gas line. Basic guidelines to operate in the area of the gas line <br />aze covered in the attached letter from C.I.G. Details for movement of heavy equipment across <br />the line will be finalized when excavation has reached this point. This phase also contains the <br />deep aggregate reserves described in Phase II. <br />Phase IV - anon-contiguous 13.24 A to the main body of the pit lying in the NW '/o NE 1/4 will <br />be the last phase of mining. By that time, Phase N will be handled as one package with the <br />entire 13.24 A major disturbance at the onset. There will be no backsloping, since the pit floor <br />will daylight to existing contours on the perimeters. After the entire 13.24 A is mined, topsoil <br />will be replaced and the areas will be ready for seeding. - To be Released <br />Phase V- amended acres as part of the land swap- 16.9 acres that lie south of Phase III - be <br />be matched to phase III - 3: 1 slopes north -south <br />(f) Narrative information from map in Exhibit C. <br />(i) Nature, depth and thickness of the deposit and thick ness of overburden to be removed. <br />As stated eazlier in this Exhibit, the deposit ranges from 8' in depth on the north and west <br />perimeters, to a maximum depth of 24' in the major portion of the aggregate body. Cascajo <br />Soils are cobbly with limited topsoil of 6" - 9". The remaining material is usable aggregate. <br />There is no overburden. <br />(ii) Nature of the stratum immediately beneath the material to be mined. <br />The stratum immediately beneath the aggregate body is a yellow shale material. <br />
