HOW TT Is DONE.
As applied 10 Bingham. the first
move is Go remove the Gaping or
"overburden' everything the ore depos-
It's This is called stripping" and
when this is accomplished the ore IS
exposed ana ready for mining lu about
the same manner that the capuiug is
taken of. The ground is taken down
ln benches and very good idea OF this
method can Doe gained by the accom-
pduylug illustrations. These benches
are usually from 80 10 90 feet hich.
Where hard rock or ground is sueouu-
tered, DO is lo0seucd by sinking holes
