EXHIBIT D <br />1. General Mining Plan <br />MINING PLAN <br />The permit area for the site is 41.4 acres. 30.7 acres of that area will be disturbed as part of mining <br />operations. Gravel for use in making construction materials products will be mined onsite. Placer <br />gold recovery will take place as the primary production commodity when processing material. <br />Because most of the site is historic mining, concurrent reclamation as commonly practiced is not <br />possible. Mining will take place from the existing surface down to roughly 100-120 feet. Mining <br />slopes will be roughly vertical in the 340' x 340' active pit. Groundwater is found at 100' to 190' <br />down, depending on location. The operator has never hit groundwater on the 110 permit area, <br />despite mining close to 100 feet down. <br />The mining will take place in three phases, and proceed north to south in each phase. Reclamation <br />of the mining area will begin once final mining is finished in portions of the mine, when additional <br />mine floor is not needed for operations. Table D -I shows the area of mining shown on Map C-2. <br />Map C-2 shows the extent of the areas mining will cover; concurrent reclamation will take place, <br />meaning mining will be confined to one phase at a time. <br />Table D-1 Mining Areas <br />Phase <br />Area <br />1 <br />3.5.0 <br />Acres <br />z <br />9.0 <br />Acres <br />3 <br />6.4 <br />Acres <br />Access Road <br />0.3 <br />Acres <br />Tota! <br />1 30.7 <br />Acres <br />Note: Phase 1 includes the 110 permit disturbance area <br />Mining will stay at least 60 feet horizontally and at least 20 feet vertically from the Middle Fork of <br />the South Platte River. A 50-80 foot berm of natural material will be maintained on the north (river) <br />side of the mining areas. Reclamation will grade out this ground to create the final daylighting <br />slopes. Mining activity will stay at least 30 feet away from the permit boundary. Mining will be <br />over 1000 feet from CO 9. Mining will expose groundwater. It is anticipated that water will be <br />reached at roughly 50 feet below the natural grade.
