Mary's Mountain Gravel Pit Mining Plan <br />This is an open pit mine located approximately 14 miles west of Pryor, Colorado. Mining <br />access will be via County Road 312 and existing roads either accessible or owned by the <br />landowner. Periodic grading will be necessary to keep the road in its present condition <br />and to make it passable. It will remain after mining is complete. <br />The anticipated life of this mine is between 8 to 10 yeazs depending on the amount of <br />material in the mine and market demand. The mining process will begin on the north <br />side of the mine, where material had been removed in the past. There is an open area <br />that was leveled at that time, which will allow us to mine into the gravel bank. The initial <br />preparation of the surface above this bank prior to extraction of the sand and gravel will <br />consist of stripping the vegetation and topsoil and placing it in stockpiles for use later <br />during reclamation. Topsoil will be kept separate from product stockpiles. Front-end <br />loaders, scraper, and motor graders may be used for this operation. <br />Following the removal of the vegetation and topsoil, the sand and gravel will be <br />extracted. This will be accomplished with front-end loaders, dozers, scrapers, backhoes <br />excavators, draglines, or any surface mining type of equipment that is economically <br />feasible for this site. As this is an open pit mine, mining and construction equipment <br />designed for this task will be used for earthmoving and transporting both on site and <br />trucking off site. The sand and gravel will be excavated, and may be moved to a <br />conveyer, screened and stockpiled. A reserve of specification aggregates will be created <br />on the site as mining progresses. Once there is an adequate supply, the processing plant <br />will be moved to another site and the processed material will be removed as needed. <br />No water diversion or impoundments are planned for this project. <br />The size of maximum disturbance will be approximately 9.5 acres. This will consist of a <br />combination of mining, processing, stockpiling, and reclamation. The various stages or <br />phases of the operation will be dictated by mazket demand. This mine will not be a <br />phased operation, but will be based on a floating bond of 9.5 acres affected at any one <br />time. As mining progresses, reclamation will follow. After an area is mine, the back <br />sloping and contouring of the sidewalls and pit floor will be done, and topsoil spread for <br />seedbed preparation, and as weather permits, planting will be done. All of the <br />reclamation will be accomplished in a timely manner in order to establish the vegetation, <br />
