tC the ore bins situated along the
tracks of the new electric railway
which connects the Victor shaft with
the mill. The larger pieces are
shaken off the grizzly, sprayed by
streams of water from a washing
apparatus as they drop onto a
broad, uptilted belt c%onveyor, and
then sorted by a force of four men.
The small chips and pieces which
escape the grizzly are carried,
by gravitating force of the water
from the sprays, in a direction op-
posite to the action of the oeit
conveyor, u through a small
trough to a settling tank outside the
building. thus saving n values that
might possibly be contained in
these small fragments of rock.
The big rocks, after being sort
ed, pass through two crushers separ-
ated by a sizing trommel, these
crushers reducing the rock success
sively to smaller dimensions. After
leaving the second crusher, the ore
is carried up on the same con, eyor
leading from the fines chute 10
the ore bins, for delivery to the
electric tram.
The waste rock is conveyed by
another belt Immediately to the
dumps.
Tonopah Mining Company
In accordance with the policy
maintained by the officials of the
Tonopah Mining company, extern
sive development work is under wa
at the Sand Grass workings at he
extreme western end of the COM
pany's estate, in close proximity 10
the important developments which
have within the last year been
made in the Tonopah Extension Min
ing company's ground. This work
is being pushed ahead on the three
deep levels of the Sand Grass claim,
namely, the S00-foot, the 1140-foot,
and the 120O-foot depths.
The fact that recent reports ia e
shown a substantial increase in the
amount of development work per-
formed during the successive weeks;
that arrangements are now being
concluded to increase to a marked
degree the capacity of the Sand
Grass shaft by the installation of
bigger and more powerful hosting
equipment; and hat this, the lat
est report, sets forth hal new work
is being undertaken in this section
of the mine, would suggest that the
Sand Grass workings are to be given
the most thorough development pos
sible, and leads to the assumption
hat important announcements as
to the success of these operations
will be made so soon as the work
has been carried forward sufficient
ly to demonstrate the possibilities
of this section of the mine.
When the new hoist, with its
requisite accessories, shall have
been completely installed at the
head of the Sand Grass shaft, the
Tonopah Mining company will have
an equipment hat will compare
favorably with any in the distl lct,
and one capable of taking care Of
a vast amount of work.
Besides the present and contem-
plated development operations in
the Sand Grass claim, the usual
vigor was displayed by the manage
ment in every other section of the
mine where production, exploration
and development work was recently
put under way.
This includes the surface and
deeper workings on the Mizpah
claim; the usual work in the Silver
Top territory, where tonnages are
coming from the South Dipping and
the Burro No. 4 vein, and where
work projected to develop the veins
in this section is being rapidly ex-
tended; and the operations in the
Red Plume claim, where as dill
gent effort is being made to demon
strate the continuation of the Mac
Namara vein into the TOnopah Min
ing company's ground.
The report of mill operations of
the Tonopah Mining company for
the week enQlng AuSuSC sra, SHOWS
that an average of "a stamps were
kept dropping and that 2135 tons
o. ore were put through the mill.
The ore averaged $12 per ton.
