osoas <br />Exhibit D -Mining Plan <br />Overview <br />Banks and Gesso, LLC <br />The extraction area at this site is approximately 33 acres located in the east-central <br />portion of the permit boundary. Site preparation will include topsoil stripping using <br />suitably sized earth moving equipment. The topsoil will be stockpiled in two areas within <br />the permit boundary as shown on C-2. There is not expected to be any overburden. <br />Raw material will be excavated with front-end loaders and scrapers and be processed <br />using an in-pit portable power screen. Undersized material will be stockpiled as reject <br />material to be used for reclamation. The remaining material will be placed into trucks for <br />transport to the applicant's processing plant in Colorado Springs. There will be no <br />dewatering, as this operation is not expected to encounter groundwater at any time <br />throughout the life of the operation. <br />Earthmoving Operations <br />Stripped topsoil will be stockpiled on the north and west edges of pit (as shown on <br />Exhibit C-Z) for later use in reclamation. There is not expected to be any overburden. <br />Mining will begin in the middle of the pit and move north and south outward towards the <br />edges of the site. The area will be mined to a slope of approximately 1.5H:1 V (angle of <br />repose), to a maximum depth of 40 feet. Reclamation of the east slopes will begin as <br />soon as mining has been completed in the area. The slopes will be backfilled with reject <br />material generated on site and/or from non-saleable (reject material) sand that is <br />returned to the site from the processing plant in Colorado Springs. Topsoil will be placed <br />once an area has been backfilled to its final reclaimed slopes, and revegetated. <br />Water Diversions and Impoundments <br />All water that may be present on site will be directed either into the pit, or into on-site <br />diversion ditches and sediment ponds (as shown on C-2), where it will evaporate or seep <br />into the ground., Water used for dust control will be trucked in from off-site. There are <br />no surface water features, and the operation will not intersect or consume groundwater. <br />Mining Details <br />This site will not be mined in specified phases. The mining direction will move outward, <br />north and south, from the center of the pit, gradually disturbing more land as the mine <br />gets deeper. The mining will commence with topsoil stripping of up to 15 acres in the <br />center of the pit. The mine depth will increase as the disturbed area expands laterally. <br />This method of mining will continue until maximum deposit depth is reached and all <br />reserves have been mined. <br />Description of Overburden, Deposit and Underlying Stratum <br />An average of 6 inches of topsoil will be removed from the mine area and stockpiled for <br />future use in reclamation. An average thickness of approximately 40 feet of eolian sand <br />exists across the mine area. <br />Oglebay Norton Industrial Sands, Inc. February 2, 2006 <br />Jemadojin Sand Mine Page 8 <br />
