Topsoil and weak surficial materials removed from the various element footprints will be salvaged and stockpiled/placed in bunds for use in the future site rehabilitation. Topsoil in the WRS footprint will be progressively removed as layers are built up. Table 13 summarizes the estimated volumes for the main elements by quarter and year.
