MINING PLAN (coNT) ~ • Exhibit C
The slab stone area will be mined from the west to the east.
This is done since the rock being mine is primarily on the surface
along the west side. Mining will begin by lifting exposed slab
rock with a fork lift. This breaks the stone into large slabs that
are bulk loaded or placed on pallets for delivery. The nature of
the deposit is such that it is exposed in this area and the upper
surface is very rough. Rather than try to strip topsoil from the
first layer of stone we will lift the stone and remove the
topsoil\overburden from the rock. The soil accumulates on the next
layer of rock that has a fairly uniform level surface. It is then
recovered from this smoother surface and stockpiled for use when
reclamation begins or respread on areas where mining is done. Once
the topsoil\overburden is stockpiled, the next layer (strata) of
stone is removed. Each stratum of stone varies in thickness from
4 to 20 inches. Mining continues in this manner until all usable
stone is removed from the area. We expect to excavate the upper 6
to 12 feet of stone off the west area before mining is done. The
configuration is shown on the Reclamation Plan Map.
This deposit of rock is layered sandstone lying under the
Stroupe extremely stony loam, 9 to 25°/. slopes soil series. This soil is
described as a moderately deep, well-drained soil. This site is
consistent with the soils description in the SCS report, as being
located on mesas and foothills. The variation in depth is closer
to averaging 8 inches on our site, rather than the 20 to 40 inches
noted in the report. In places there is as much as 30+ inches of
overburden that may be usable for topsoil if properly conditioned.
The soils map shows another soil type for the eastern part of
the site. The Nunn stony loam, 3 to 9 percent slope is described as a deep
well drained soil, grayish-brown clay loam averaging 6 inches deep
in Pueblo County. This area is part of the prelaw disturbance area
for M.L.R.B. permit number M-77-326 so the topsoil and overburden
have been removed. The soil description and pertinent data are not
applicable to this application for that reason. We suspect that
this is the material residing in the piles along the north side of
the existing permit.
This particular deposit is on a gently sloping mesa typical to
the area. The total thickness of the slab deposit on this site
varies from 5 to 15 feet and averages approximately 10 feet. We
estimate there are 144,400 tons of recoverable material on the
site. The stone found in the mined area varies in size, color and
grades. We estimate it will take 6 to 10 years to remove all the
material from this site because the demand for material varies in
type, and size. This means that there will be times when we have
