V. EXHITiIT D. MINING PLAN
The mining plan will include approximately three stages:
1. Mined land is first stripped by means of bull-dozer or
carryalls. The overburden is either stock-piled for future
use or used for leveling and filling of existing low spots.
2. Excavation is then done by a dragline loading material on
to dump trucks hauled to stock piles near processing plant.
3. The material is then processed by crushing, washing and
screening into various sizes as require3 for our concrete and
gravel sales operations. This finished material is stockpiled
by means of belts and loaders near our concrete batch plant.
(Refer to pre-mining and mining plan map of affected land for
approximate size and type of disturbance in mining operation.)
Timetables:
Estimates on time periods could vary from year to year accord-
ing to the demand for raw material for that particular year.
Normally, each year we will strip overburden from a designated
portion of land (approx. 1 acre) and this will be large enough
for the excavation process for the entire operating year.
In the past it has taken approximately from one to two weeks
to strip overburden. After that is completed, usually in the
spring of the year, we spend the rest of the operating year
in the excavating process. This would be approximately seven
to eight months, determined by the onset of cold weather in
. this region, at which time we would have to stop operating
for the year.
It should be added that ws are experimenting with a dewatering ~
system that would possibly let us move back into the already ,
excavated area and remove gravel at a deeper level. If this
is possible, our timetables and areas to be stripped each year
would change.
and Thickness of Ore Bodv:
At the present time we are excavating to a depth of approxi-
r,~ately twenty feet. The top two to three feet is composed
of dirt-like top soil and the remaining layer is a mixture
of river gravel and sand. The dragline when excavating takes
a swath about twenty feet wide and in the course of a year
probably will complete around four swaths approximately six
hundred to seven hundred feet long.
In the event dewatering takes place and we can re-enter the
pit we could possibly extend this depth to around fifty feet.
