Mining will then proceed to Area 5, the final area of mining. For the mining of this area, the facili- <br />ties (which are portable), will be moved to the backfilled portion of Area 3 to allow Area 5 to be <br />mined. The facilities will not be placed on land that has been retopsoiled. The facilities area is ex- <br />pected to be approximately 10 acres. The table below shows the drill data and average thicknesses <br />for Area 5: <br />Area 5 <br />Since Area 5 is 31.6 acres in size, an average depth of 21.5 feet yields 1,096,000 cy of <br />soil overburden. Initially, mining in Area 5 will be in a 7-8 acre area on the north end. Soil and <br />overburden from this initial cut will be moved to Areas 2, 3 and 4 to create 3H:1 V sideslopes and <br />peninsulas of land. As mining proceeds to the south, topsoil and overburden encountered will be <br />used to reclaim the northern par[ of the pit. As excavation moves south, overburden and soil will <br />continue to be used to reclaim land mined to the north as well as backfill in Areas 2, 3 and 4. In the <br />southernmost portion of Area 5, soil and overburden will be placed immediately to the south in the <br />mined out portion of Area 3. Excavation will then break through to Area 3 and this overburden and <br />topsoil temporarily placed in Area 3 will be backfilied in the southernmost part of Area 5. <br />The table below has a summary of the areas and volumes available for land area reconstruction: <br />15 Road Pit 10/02 13 <br />Hole # Soil/Overburden <br />Depth Gravel Thickness Total Depth <br />5 20.2 22.0 42.2 <br />6 22.2 21.0 43.2 <br />7 22.2 21.0 43.2 <br />8 21,2 23.0 44.2 <br />Average 21.5 21.8 43.2 <br />
