Water Flow `— <br /> Expanded Metal Riffle <br /> Fluid Bed <br /> 1 <br /> Mattis Miner's Mass <br /> Base of Sluice Box <br /> Lew Specific Gravity <br /> Q Medium Specific Gravity <br /> High Specific Gravity <br /> Figure 1. Conceptual Section of a Sluice Box. <br /> Oversize tailings will be stockpiled for use by the landowner at their request or utilized as <br /> backfill or existing and future pits throughout the site. The undersize fraction flows across the <br /> sluices and is deposited in an alluvial fan which forms along the receiving edge of the settling <br /> pond. The processing plant will be located at a higher elevation relative to the remainder of the <br /> operation to allow for good depositional flow into a previously excavated pit without significant <br /> rehandling, see Map E-2. <br /> As portions of the site are already mined, very little overburden and topsoil will be recovered <br /> from these areas. However, undisturbed mining areas will have limited topsoil and overburden. <br /> Any topsoil, overburden, and separated waste fines from the unmined areas will be used during <br /> phased reclamation as mining progresses through the site, see Map E-3. Reclamation will occur <br /> concurrently with mining and is detailed in Exhibit D. <br /> Bancroft Placer Mine 4.nj i,—Ji,f.d.b.«9.tes PIRA <br /> July 2020 C-2 <br />
