<br />MINING PLAN <br /> <br />EXHIBIT D (coot) <br />Step 9 -After Stage A is mined out, topsoil will be stripped from Stage B and placed directly in the <br />regraded Stage A area. Mining will then begin in Stage B and the plant facilities and disturbed area <br />will move as a " 30 acre unit", with topsoil stripping and replacement occurring at frequent intervals, <br />performing continuous mining and reclamation until the deposit is fully mined out. All newly <br />topsoiled areas will be drill-seeded, fertilized and crimp-mulched within 6 to 8 months. Also, <br />irrigation will be returned to as much area as possible, as quickly as possible. While mining in Stage <br />B, all of Stages C and D can remain irrigated in their natural condition and most of Stage A can <br />return to irrigation use. The sight berm is left intact. Estimated soil stripping depth in this area is <br />from 10 to 16 inches. Sometime during the mining of Stage B, the powerline will be moved to allow <br />for full mining of the terrace. B&B will work with the power company on this move. <br />Step 10 -Mine Stage C, performing reclamation as the pit advances. Estimated soil stripping depth <br />in this stage is 6 to 12 inches. The western edge of the pit will be cut to a slope of 3H: i V. <br />Step 11 -Mine Stage D, performing continuous reclamation as the pit advances. Estimated soil <br />stripping depth in this stage is 6 to 12 inches. <br />Step 12 -Remove the sight berm, using atrack-hoe or hydraulic excavator, which will be used to <br />draw the outer side of the slope back in the excavation area. This will keep material from being <br />dislodged and possibly reaching the road adjacent to the site. The equipment will operate from <br />behind the berm, most of the time out of view from the traffic along the Colorado River Road and <br />Coffee Pot Road. Again, reclamation will proceed continuously behind the stripping operation. This <br />will result in minimal visual impacts from this final part of the operation. <br />The total berm volume moved is approximately 950,000 cubic yards or 1,425,000 tons. Three- <br />dimensional computer modeling of the mine plan shows that the volume of material excavated in <br />each stage and the berm is as follows: <br />16 <br />
