P-3 Mining in the 5th phase will begin by backfilling over- burden temporarily stored on the surface, back into the area mined in phase 4. Next a portion of the topsoil removed from the south side of phase 5 will be stock- piled on top of the backfill in an orderly berm, followed by a berm built from a portion of the overburden on the south half of the 5th phase. Toward the north boundary a similar process will be followed, creating two berms of material. As in phase 4, mining will proceed from east to west on a face almost 175' wide. When all mining is completed (presently estimated to be 1995 - 2000) back- filling and final grading will be completed as set forth in the Reclamation Plan ( See Exhibit E - 1 ).

'Exhibit E - Reclamation Plan Reclamation will be completed in three general phases. The first phase will involve backfilling along the granite walls created in the first three phases of mining. Back- filling should begin about the time phase 3 is completed and when major preparation takes place for phase 4. The overburden removed in the 3rd phase of mining will provide adequate material (about 35,000 cuyds.) to backfill and reshape the walls on the north and south sides of the area ~~~ to a 3:1 or flatter grade. A haul road with switch-backs will need to be maintained up the first three benches i order to access the floor of the mine in the 4th and 5th phases of mining. Consequently, topsoiling on [he benches will be delayed until all regrading is completed as sho•N-n in Exhibit E-1. When mining is completed in phase 4, backfilling from the subsoil storage area on phase 5, will begin. Also, overburden stored on the south rim of phase 4 will be distributed in order to establish the finished grade along the south slope and bottom of the phase 4 area.
