Mining operations will proceed as detailed on preceding page: Stripping of soils and overburden via <br /> bulldozer, pushing material to the south margin of that phase area. After mining of the gravel deposit, <br /> overburden will be pushed northward to m/1 original location in blocks of land app. 300' wide x 400' <br /> deep. Overburden removal and replacement will continue as described across each phase area with <br /> excess overburden pushed up along pit margins on east and west boundaries if necessary until mining <br /> has exposed enough area to push to final location within the mined out pit areas exposed by gravel <br /> extraction. <br /> Please refer to Exhibit C Mine Plan Map for location of each Phase in amended acreage area. <br /> (f) Nature and Extent of Spotted Burro Gravel Resource <br /> Please refer to Exhibit C- Pre-mining and Mining Plan Map as well as Soils and Vegetation Maps <br /> The Spotted Burro Pit is characteristic of a geologically recent alluvium deposit of outwash silt, sand, <br /> gravel and boulders up to 2 feet in diameter derived from erosion and stream transport of primarily <br /> Pike's Peak granite bedrock outcropping well north of the present gravel deposit location. The gravel <br /> thickness varies with an average of 15 feet in depth over most of the permit area. The gravel zone is <br /> covered by a varying thickness of sandy loam soils described as Kim Loam, a eolian derived loess soil <br /> from 2 to 5 feet thick. While near surface soils reflect little to no "A" horizon development, the soil is <br /> described by the Soil Conservation Service to be well draining and adequate for re-vegetation purposes <br /> as well as general backfill and grading along permit boundaries. The gravel deposit is underlain by a <br /> green clay rich shale unit of unknown depth. The shale unit has shown to be a stable pit floor material <br /> that aids surface drainage as maintained towards the southern portion of the property as well as <br /> allowing for heavy equipment operation with a minimum of gravel cover. The silty, sandy alluvium <br /> gravel is excavated using Front End Loaders and processed to number of sized products(primary) from <br /> -1 1/2", -1", -3/4"road base down to-3/8" fines(secondary), in strong demand for use in waste <br /> encapsulation and liner bedding at the nearby privately operated county wide landfill. The primary <br /> gravel products are used for road construction purposes. <br /> No washing operations are employed at this time. <br /> No explosives are used in this operation. <br />
