T0NoPAH MINING.

TOROHAH MANiNG. {
The Tonopah Mining company ad-
yanced their workings SOC feet dur
ing the last week. OF this an adj
vance of 361 feet was made in the
Mizpah, nineteen feet in the Red
Plume and 126 feet in the Silver
Top. The diamond drill has reached
a depth of 437 feet, with an increase
of seventy-nine feet.
The cutting of the station at the
1200-foot level for the big pump has
been completed and now the work of
laying a foundation is under way.
Only small parts of the pump have
been taken to the station and when
the foundation is completed the re-
naming three large parts will then
be taken underground. The pipe has
been connected from the 1900 level
to the surface and is in readiness to
connect when the pump is installed.
A force of men are employed on a
drainage pipe which will convey the
waters from the surface of the mine
to the Montana ditch. The Red
Plume shaft is all in readiness for
the work of sinking and the first
shots are expected to be fired on
Monday.
Silver Top - 240-Foot Level
Work has commenced in the wester-
ly workings of this level on the cut
ting out of a stope over a block of
ore which was recently encountered.
In the east end raising is being con-
tinued on the Silver Top vein.
440-Foot Level-The crosscut,
which was started north at a point
about fifty feet east of the shaft has
cut several fair ~stringers in the hang
ing wall. Drifting is also being done
in the extreme west workings on
several hanging wall %stringers, one
Of which carries good values.
540-Foot Level-At the extreme
easterly section of this level a cross
cut has been started south on the
east side of the Stone Cabin fault.
The formation now appears to be
lode %porphyry. The crosscut south
in the west section was continued
during the week, but as yet no
change is reported.
740-Foot Level - The diamond
drill, which is operating on this level
is now working in a good formation
and excellent progress is being made
Mizpah - 20O-Foot Level - The
drift along the Mizpah fault in the
extreme east end of this level, has
been stopped and the drift to the
west along the fault again started
up. The principal work which has
been carried on during the week is
in the raise along the Mizpah fault
which shows three feet of ore. The
drift east from the second crosscut
south in the easterly workings con-
tinues to show good milling ore. The
ore In the raise over this drift has
been cut off by the fault and the
work of prospecting for the vein is
now under way.
