The following is the approximate acreage and time for mining each phase: <br />Acres per Phase Time for Mining (years) <br />Phase I 14 1 <br />Phase II <br />30 <br />Total 44 3 <br />The following equipment and facilities will be utilized in this operation: <br />Conveyors (2250 ft) Dozer (1) Back Hoe (1) <br />Graders (I) Loaders (2) Scrapers (2) <br />Stacking Conveyors Portable Toilet (1) <br />In order to gain an understanding of the extent of the mining operation, it is helpful to <br />know the acres disturbed by different aspects of the mine. The point in time where the <br />mining disturbance could be at its maximum, during the end of Phase II, has been selected <br />to illustrate the various acres of disturbance: <br />A. Stripped overburden and topsoil in anticipation of mining 15 acres <br />B. Active mining area 15 acres <br />C. Topsoil stockpiles 1 acre <br />D. Roads 1 acre <br />E. Backfilled with stockpile 7 acres <br />F. Seeded 6 acres <br />G. Reseeded for 20%non-germination 1 acres <br /> Maximum Total Disturbance: 46 acres <br />Surface Water Management <br />All mine areas will drain internally. Uncontrolled releases of surface water and sediment <br />from mining areas will not occur. Stormwater collected in the open pit will be managed in <br />accordance with Colorado/NPDES discharge permit requirements. Sediment generated <br />from localized stormwater runoff and surface drainage will managed according to the <br />enclosed Stormwater Management Plan <br />Water rights at the existing Cottonwood site will be used for dust control operations along <br />the roads and stockpiles at Duckworth. It is estimated that 2500 gallons a week will be <br />required to limit dust emissions. The water will be supplied using a 2500-gallon water <br />truck. <br />Irrigation Ditches <br />Idaho Creek is located within the property, 650 feet from the eastern boundary, and will not <br />be disturbed by the mining operation. <br />The Smith and Emmons ditch runs from south to north through the property and is located <br />approximately 200 feet from the western property boundary.
