EXHIBIT D MINING PLAN(coNT)
is required by the Reclamation Plan. The average depth of topsoil
on the site according to the NRCS report and site investigations is
0 to 12 inches deep. Enough topsoil will be retained to place an
average of 6-12 inches on the areas to be revegetated. As each
area is stripped, L.G. Everist will determine how much soil will be
needed to reclaim the area and it will be stockpiled for use in
reclamation. Over the life of the mine, an estimated 816, 000 yards
of topsoil will be stripped from the mined area but, a minimum of
241, 500 yards will be retained for resoiling the areas to be
revegetated. In addition, there is from 0 to 3 feet of overburden
on most of the site . Much of this overburden will be retained and
used to backfill the areas shown on the maps or removed from the
site .
The topsoil and overburden stockpiles will be located around
the excavation, typical piles in possible location are shown on the
MAP EXHIBIT C-1 - MINING PLAN MAP. If the soil stockpiles remain
undisturbed for more than one year, a cover crop of the approved
seed mix, at the rate called for in the Reclamation Plan, will be used
to revegetate them.
MINING PLAN
MAP EXHIBIT C-1 - MINING PLAN MAP shows the approximate direction
of mining as it progresses across the site . The plan is for having
180 acres ± of disturbance bonded to allow for flexibility during
mining. This 180 acre area will include stripped, partially mined,
partially reclaimed, Plant Site, materials stockpile area and
future reservoir areas . As mining progresses across the property
some parts of the property will remain undisturbed while other
areas will be either, stripped, mined, partially reclaimed or
totally reclaimed. The MAP EXHIBIT C-1 - MINING PLAN MAP shows how the
area will look when approximately 23% of Phase 2 , and all of Phases
lA and 2A are mined and partially refilled. Note how the final
slopes around the perimeter of Phase 2 are created as mining
progress by leaving undisturbed material in the slopes . So only the
working face area would need to be shaped, and 20 acres would need
to be resoiled, if mining ended at this time . Also in this snap-
shot in time, the reclamation in Phase 1 would be complete, and
Phase 3 would be Plant Site, equipment storage and stockpile area.
Of the 643 . 30 acres ± in the permit area, approximately 508
acres ± will be disturbed by mining. This mining plan details the
development of the mine site with 2 options . Option A will has a
series of eight (8) developed water storage reservoirs using slurry
walls around each reservoir. Option B has six (6) lined water
