Overburden Replacement; Division of :~n:rals & Geology <br />The existing A/B horizon soils will be stockpiled on the east side of the pit for reclamation. A 6" <br />to 12" layer will be placed over the entire site upon reclamation and prior to reseeding. <br />Reclamation will occur at the end of the mine life and will not occur in phases concurrently with <br />mining. <br />B. Gradient of Reclaimed Slopes; <br />The pit will have 3H:1 V slopes on the mined faces. The pit floor will be uniform and slope at <br />approximately 2% to the outer edge of the mine site. Berms used to control mining activities will <br />be removed to return the site to a natural look. Cobble rock will be placed in runoff locations to <br />curtail head-cutting due to precipitation. <br />C.

Based on the natural dry conditions of the <br />site no shrubs have been selected. This decision is in harmony with the existing native conditions. <br />Reclamation Seed Mixture <br />eci s % of Mix PLS Drilled Ib/ac <br />Alkali Sacaton 10 0.10 <br />Galleta 45 2.70 <br />Sand Dropseed 5 0.015 <br />Needle-&-Thread 40 3.00 <br />IV Seeding Method; Seeding will be accomplished by drilling if possible, a high rock <br />content in the soils may interfere with drilling the seed. If necessary the seed application rate <br />would be doubled to accommodate broadcast seeding. Seeding will occur during the fall <br />(November) or early spring (March) in order to take advantage of available soil moisture <br />conditions during the spring. The seedbed should be firm and the seed planted to a depth of about <br />0.5 inch. In the event that seed is broadcast it will be incorporated into the soil by light disking or <br />harrow. <br />In order to help create moisture traps, following seeding, a dozer will traverse the slope in <br />an up-and-down manner so that the long axis of the track imprints are parallel to the slope. <br />V Mulching; No changes <br />VI Shrubs and Trees; No Changes <br />
