RECEIVED EXHIBIT D SEP Q 2 20b3 ~llris(on of Minerals and Geobr~y (Reclamation plan rule 6.3.4 (1)) The proposed tailings disposal area, fifteen (15) to twenty (20) feet deep, will hold approximately one hundred eighty (180) tons of fill; which will be blended with 35% waste rock, (sandstone from the mining area), directly above six (6) to thirty-six (36) inches 15% soil and crushed sandstone (gravel) as needed for compaction, and 50% spent tail, whose moisture content is 20 to 25% , for a well graded backfill material, with 50% or more retained on a # 4 sieve, to provide quality assurance that the blended backfill is acceptable. Backfill will be placed into (roughened surface) area, to assure a good bond between bedrock and backfill. Backfill will be placed in at two (2) foot depths, then compacted by a minimum of four (4) passes with a backhoe, compacted to a minimun of 90% maximum acheivable dry density. Each new two (2) foot lift will be added on scarified or roughened surfaces. The area will be capped with at least five (5) foot of compacted fill rock, (sma116' or less) and soil. The one (1) foot portion of cap immediately above the tailings, to be compacted so the permeablity is 10 cm/sec, or less. The level of fill will be one (1) foot below the level of the lowest elevation in the proposed area. The permameablity and sieve tests, to determine if the tails have enough clay content to meet the compaction and permeablity standards, will be included in the annual reports, to be tested by Inter Mountain Labs or a compentent geologist. Storm water diversions will be placed on the east and west sides of the proposed tailings disposal area (see Exhibit E and Plate 1 Technical Revisions). Storm water will be channeled off into the contoured depression azea below audit # 2 on the west side, which is approved for such (Exhibit E). The east end diverted down gradient onto talus, sixty (60) feet above the bottom road, which is a storm water diversion (road cut to inside of mountain) to the bottom of permitted azea. No water will leave permitted area. There will not be any standing water left on the proposed area by grating, thereby lessening the amount of perculation into the proposed area. The proposed area will be covered with waste rock (sandstonte and limestone) and crushed gravel, to conform to the surrounding contours east and west. Top soil will not be applied as the area will not hold soil, due to washing down by natural forces and setteling down into the openings between the rock. Same on the east and west ends of the area. The finished slope will be grated to 34 to 38 All compaction to be done with backhoe, minimum 4 + passes, to achieve desired compaction. At current levels of mining, seventy (70) tons or less per year, the proposed area will be full and reclamated in two (2) to three (3) years, possibly less. The criteria relied on in this exhibit is in the current Mining Plan, the current Enviromental Protection Plan, and the current Reclamation Plan, approved by the Division of Minerals and Geology (1986), some of the plans are in correspondence between permittee and the Division of Minerals and Geology. Dates on such correspondences are 12/05/94, 11/22/94, 02/08/95, 02/21/85, and 02/25/95 and are in the Division of Minerals and Geology file. The future land use is forestry (see Exhibit E and Plate 1).
