Tonopah bonanza. [volume] (Butler City [i.e. Butler], Nev.) 1901-1909, 1909-06-19

amount Of air needed and the man |
agement is at present waiting the
arrival of a new compressor ordered
some time ago. The development
work for the week totaled 237 feet,
which was divided as follows: Miz-
pah 1863, Silver Top 20 and the Red
Plume As feet. The Mizpah shaft
was lowered twelve feet and has now
attained a depth of 1926 feet with
no change in the formation.
In the Silver Top workings, moth
ing but stopping is being done above
the 540-foot level. The slopes are
being carried along east and west of
the shaft on the 240, $40 and 440-
foot levels, the Silver Top vein pro-
ducing the bulk of the ore east OF the
shaft an" the Valley View vein west
OF the shaft. Both veins show an
average width of from four to five
feet ON the various levels and carry
good milling values.
540-foot level-Work has been re-
sumed in the west drift from the
south crosscut from the main west
milling ore in the top. The raise
from the intermediate drift under
the Mizpah fault is being sent up on
three to four feet of milling ore, the
vein showing up considerably strong
u er in the raise than at any time in
the drift.
Z 5O0-foot level-A new raise is be-
. ing put up on the Mizpah vein under
the east stope, for the purpose OF
more easily handling the ore opened
le up in the footwall of the stope. The
d east intermediate drift from the
t, Brougher shaft, which is following
o. the Mizpah vein midway between the
500 and 600-foot levels, continues to
lg show a good face of ore, the veir
averaging about five feet in widti
n and carrying good milling values.
