EXHIBIT L
RECLAMATION COSTS (revised 10/31/2019)
The following Reclamation Cost estimate is based on the
assumption that there will be restricted no more than 40 . 0 acres ±
of disturbance at any-one time, as shown on the Mining Plan Map. The
mine working face will be 500 feet long by an average of 35 feet
high and would need cut/fill sloped at 14 . 16 yd/lft . Finish
sloping on the 1, 675 feet of partially backfilled 2 : 1 slopes that
averages 35 feet high at 5 . 68 yd/lft to complete the 3 : 1 slopes .
Armoring will the be placed along 500 feet of the channel side
slopes using 1 . 64 cubic yards/ linear feet (820 yd') of clean
concrete rubble . The 30 acres will then be resoiled with an
average of 5 . 5 inches of soil using a scraper to spread it and a
blade to shape the seed bed. At that time we will have to respread
22, 185 cubic yards of topsoil and move 16, 600 cy of cut\fill
sloping along the working face . The remaining 10 acres are
partially reclaimed and are waiting grass to grow so may only need
reseeding. The table below outlines the various areas of distur-
bance at the time explained above . A D8N dozer is used to do the
cut/fill sloping, a 631G scraper will resoil and complete bank
sloping and a 140G Blade is used to shape the reclamation area .
The mobilization haul distance is 25 . 0 miles at a average speed of
45 mph . The revegetation cost figure used includes fertilizer,
grass seed, labor and drilling costs .
