As can be seen from Table 2.05.4(2)(d) -2A, there is sufficient topsoil and subsoil volume between stockpiles and currently (June 2010) undisturbed areas to replace the prescribed thicknesses over the Morgan property. While the amount of Lift B Topsoil available is 17 cubic yards short, this amounts to less than a 0.004% deficit of thickness over the Lift B topsoil replacement area. Considering that any swell of topsoil that is stripped from fresh ground is left out of the above calculations to be conservative, it is likely that the deficit of Lift B Topsoil shown above will be erased by some swell. The 93% recovery rate is only applied to the topsoil at the point of salvage. This is to incorporate the loss of some topsoil and subsoil (Lift A and Lift B respectively) due to efforts to avoid excess rock fragments and general salvage methods (soil strata undulate, while the stripping is roughly flat). The 93% has therefore only been applied to the "Ahead of Pit" volume calculations, and can be seen on Table B of Map 2.05.4 -6. Stockpiled topsoil recovery is treated as 100 %, since soil losses from handling will be negligible. Calculations demonstrating the quantities for the reclamation are shown on Map 2.05.4 -6 and are described below: Revised PR 06 June 10 2.05.4(2)(d) -31
