il will be surprising indeed If the
vein does not show an increase in
width with a betterment in values
corresponding to the appreciation OF
the grade in the winze as compared
with the returns published in the
reports when the mammoth stope on
the 1540-foot level commenced sup
plying the mill with increased ton
nages in the early part of 1916.
Tonopah Mining Co.
The latest shipment of bullion
from the Tonopah Mining ompany's
plant at Millers, known as the Des-.
ert Power & Mill company, where all
the ore extracted in it's mining opera
tions are treated, indicates that the
company is continuing to operate at
a profit on the production OF the To-
cal mine. There were 80 bars of
gold-silver bullion melted down
from the last cleanup, and the esti-
mated valuation is $62, 900, proving
that the mine and mill are main
tanning the regular averages of pro-
duction and extraction that have
been reported consistently during
the present year.
The cleanup, which was the sec
ond for the month of November,
came as a result of the preceding
two weeks treatment of ore, during
which period the tonnage shipped
from the mine to the mill has been
around 1900 tor per week. Com
pared with the previous reports,
particularly those made annually by
the company, the results show that
the efficiency of the mill is main
tianed at a high standard, aid the
average rate of extraction has not
diminished with the reduction in
the grade of ore treated.
The report of mill operations for
the week ending n V. "a shows that
an average of sc stamps were kept
dropping and that 200 ons of ore,
of the average value of $3.50 were
put through the mill.
The company performed a lesser
amount of development work dur
ing the past week, as compared with
previous periods, the total amount
of work, according to the measure
ments taken oy the company Off
cials, having been 141 feet. The
Silver Top workings accounted for
80 feet of the entire advance; 16
feet of work was done in the Mizpah
workings, and at the Sandgrass
claim, ~ feet of underground de-
velopment was recorded.
In the Silver Top territory, on the
240-foot level, 234 drift, on the
vein north of the shaft, was discon-
tinued during the week, owing to
the streak of vein matter having
become too small to follow profit
ably, and there being little promise
of betterment showing at the pres
ent time. A raise is being started
on the vein where it disclosed the
BEST width and values. this being at
a point EAST of the shaft. Raise
300. on the same vein, has under
gone no particular change since the
previous report was made, occasion
al spots of ore showing as it ad-
vances.
Jim Butler Mine
Aside from the report of the
Tonopah Belmont company showing
the output of bullion at it's Millers
plant, the main feature of the Jim
Butler for the past week
has been the various items of prog
gress on the Wandering Boy vein in
that section of the property. The
bulk of the work in the mine has
been done on the vein mentioned,
and at some points satisfactory i'm
provement in widths and values
have been noted.
The increases in the width OF the
ore and the betterment of the val
ues constitute the most gratifying
feature of the recent work along de.
