TONoPAH MINING.

IL credited WITH llo ~ Ieeti the tteu
plume with forty-two and one-half
feet and the Mizpah with 227 feet.
The Red Plume shaft was extended
twenty-five feet and is now down a
total depth of 619 feet. Fair pro-
gress was made in the Mizpah shaft,
the three compartments being ex-
tended fifteen feet. This shaft is
now down 1886 feet from the sur
face. No change has been encount-
cred in the formation, rhyolite-da-
cite continuing in the bottom. At
the 13S0-foot point a crosscut was
started to try out the territory in
this section, as the management be-
Heyes they have reached a point be-
low the water flow. and If this ross
cut shows this to be a fact, it will
circle the shaft and the flow will be
caught. The flow remains between
hfty-fve and sixty gallons a minute.
AT the 500 or bottom level of the
Red Plume, the sinking has been
stopped while the work of cutting out
Of a station is in progress.
Mizpah, 200-foot leyel-The north
west drift under the Mizpah fault
was sent ahead during the week on
elghteen-inches OF low grade ore.
300-foot leyel-The west drift
rom the south crosscut from the
nain east drift, which has been fol
owing an eighteen-inch streak OF
milling ore, has lost the ledge and
the direction Of the drift has beer
turned TO the north in an endeavoi
to locate the missing vein. The in.
ter-leyel from the stope under the
Mizpah fault, which has been on ore
under this level, has lost the same
on a fault and work is being done in
an effort TO pick up the lost ledge.
400-foot level-The northwest
drift under the Mizpah fault has beer
o a broken up formation during the
asst week and has lately began to
bow a small amount OF quartz carry
ag a few values. The south cross
at from the main east drift was sent
head the usual distance with the
ACE continuing IN andesite. This
gosscut is prospecting a new block
d ground and the chances for the
Fcking up of an ore body are very
iayorable.
50O-foot level-An EAST drift has
been started on about eighteen
inches Of quartz that carries milling
Values. This quartz was interseeted
BY the south crosscut from the mair
vest drift.
6OO-foot level-The south crosscur
rom the Red Plume shaft which II
being sent out for prospecting pur
poses Is still in the andesite. A
outh crosscut from the main cas-
dFit In the Mizpah side. was sen
mead during the week with the face
IA andesite.
Silver Top, 100-foot level-Fol
'e hrst time in several years worl
aas been resumed on this level. TIL,
'outh crosscut from the west drift
as a body of mill ore about eighteen
inches In width and drifting was re
sumed at this point.
zio-foot level-The usual stopping
vas conducted during the week Oh
me Valley View vein.
afO-foot level-The east drift Il
~ footwall of the west stope con
uaues to show about three feet o
Viii ore, Stopping is being carrie,
west of the shaft on the Vale
,ew vein and East of the shaft O
NO silver Top vein.
i4V-foot level-The west drift O
'ae iootwall side Of the west stop
Oeing sent ahead on from three I
"uf feet OF low grade ore.
OfV-foot level-The south cross
rom the main east drift inter
one foot of good milling or
ing the week. This crosscut is b,
'ent ahead to the south with tn
aVe IN andesite. The south eros,
"om the main west drift ha
,eu up between three and fou
u a broken up material of 10,
&c. milling ore. Work has bee
