MINING PLAN EXHIBIT D(CONT)
Mining will begin on a section of the slopes created at the
end of the last mining cycle until a near vertical face is open.
This face will be worked to the north and south until it extends
across the property and at that time mining will progress to the
west . As mining progresses thru the site the processing plant
will be set near the open face to reduce the haul distance from
the mine face .
This pit will be operated year-around by Colorado Crushing,
Inc . , weather permitting. There may be periods when the demands
for material are slow and no mining will take place at which time
the mine will become an Intermediate Operation. Stockpiles of
material will be maintained on the site and as the 'need arises,
it will be hauled to our project sites or sold to the public .
This will be a single stage operation, but the amount of
disturbance will be limited to 20 . 0 acres or less at any-one-
time . This will allow us to use approximately 15 . 0 acres as a
processing plant/stockpile area and approximately 5 acres for the
active mining area. As mining progresses around the property the
bank slopes will be mined or shaped to the required grades where
they are in their final location. This will reduce the amount of
work that has to be done to reclaim the site . Reclamation will
begin once we have enough room for the stockpiled material and
the newly mined section, to be reclaimed so it will not have to
be disturbed again.
Review of MAP EXHIBIT C-1 shows how we expect the site to look
when mining is approximately 38% done . Note, the floor of the
excavation is flat and the exterior slopes into the mined area
are graded 3 : 1 where reclaimed, 2 : 1 when temporary grading is
done and near vertical where mining is taking place . There is
adequate overburden that can be used to backfill the exterior
slopes if needed, even if Option 1 reclamation is followed.
We have developed two Options for the reclamation plans for
this mine so in the future we will only need to file a Technical
Revision to implement the changes for Option 2 if needed.
Mining equipment may include but is not limited to, front-
end loaders, scrapers, bulldozers, dump trucks and a water truck.
Processing equipment may include but is not limited to conveyors,
crushers and screen plants . A scale and scale house as well as a
shop and maintenance building may also be built at the mine
during its life . No blasting will take place at this mine .
As much as possible, the surface drainage will be maintained
in the same direction as it now leOxists . The proposed sloping
