From Tonopah Minerl.

The campaign of active development
that has marked the operations of the
fouepah Mining c%ompany's mine dur
ing the past year was continued stead
ly during the week, resulting in a total

and raises for the year will amount
TO over FIVE miles. and a correspond
ingly great amount of new territory
will be opened up The most notabl"
part of this development is in the
form of crosseuts, which are opening
up the territory in the foot ahl
hanging-walls of the old Mizpah and
Valley View veins, showing them
each to be n system of veins rather
than single ones, rs they were at first
regarded. A considerable amount of
work has also been done ia the Burro
veins and 4 large amount of ore has
been extracted from them without OK
hausting their possibilities. Work
from the Red Plume shaft has been
pushed ahead with the usual energy,
and a gratifying tonnage of ore
blocked out there stands ready for
extraction when it IS needed. The
ore bins and trestle AT the Red
Plume shaft have been completed AMI
placed in operation, and every thing
is found to work smoothly and salts
factorily, to the credit of Assistant

The mill report for the week end

of 90 stamps out of 100 were drop

of ore, of an average value of $22

Work of installing the Gre washing
and sorting plant at this property IS
nearing completion. An ore
bin of $50 tons capacity has been built
at the collar of No. 3 shaft. This bin
lined with steel rail. In this bin the
secord class ore will be dumped, pass
ING through three chutes to a 30-inch
steel belt conveyor which feeds a l0x20
inch Blake crusher. From this machine
the ore falls into 4 pit, rom which
is elevated by means of an lS-inch
bucket elevator to a crane ore washer,
which is an exact duplicate of that
installed at the Belmont mine, where
the ore is screened IN a trommel or
revolving screen, the fines passing
through 1-inch punched steel screen, the
of oversize going TO the ore
washer, where it is thoroughly washed
and then dropped onto a 40-inch pick
ing belt, where the waste and barren
quartz are sorted from the ore, and
the result is a shipping product which
is sorted from a grade of ore which
otherwise could not be handled and mar
keted at a profit and which heretofore
the mines of Tonopah have been com
pelled to leave untouched in their
slopes. This mine is rapidly being
opened up and tie new work is de-
~veloping large bodies of ore which will
be profitable when sorted in the o-s
