formation of the mill into an all
slime plant will undoubtedly mean
that the irregular extraction which
ensued when the ores were treated
under the duplex system of parting
sands from the shines and treating
each separately, will give way to the
more uniform results that have been
shown in the recent tests on the
shining process.
To confirm the report hat a de-
cision had been reached by the White
Caps management to make the al
terations mentioned, John G.. Kirch-
en-, general manager, authorized the
following statement:
ION account of the very success
full extraction of the gold values in
the shines. which now represent
about 80 per cent of the tonnage
treated at the mill, it has been de-
cided by the White Caps Mining
company to slime all the product
rather than to continue with the
slime-sands process. A tube mill
and other machinery are now being
installed and will be in operation in
about three weeks. The addition OF
the shining equipment will not ne
cessitate any closing down of the
plant, and while the installation OF
the new machinery is being COM
pleted the mill will continue operat-
ing as at present.
when the tube mill and other
accessories have been put in COM
mission, the cleanups will be made
twice a month regularly. The last
cleanup has just been finished, and
the gold product arrived in Tonopah
Yesterday on it's way to the mint.
The last cleanup was entirely salts
factory to us; and when the new
all-slime process is in complete order
the regular semi-monthly cleanups
will be larger and of course more
valuable.
"The basic principle involved in
the mill process. e., the low tenn
perature oxidation of the ore in the
Wedge furnace, and its subsequent
treatment by cyanidation-has al
ready proved to be as successful as
we had anticipated, and the later
steps we have taken are merely pro-
gressive ones in the matter of re-
finement of the entire mill process
The weekly report on the White
Caps operations was not included in
the report sen out yesterday, as 1t
was thought best 10 await the melt
ing of the Partial cleanup Of pre-
cipitates which were treated at the
Tonopah Extension refinery. For IL
DAYS run, the partial cleanup showed
400 pounds of precipitates- which
when refined produced 1919 ounce
of gold valued at $1,000, which
demonstrates conclusively the great
profits which the company will make
when the mill is working up to ca
pacity and it's savings. brought up

There is nothing new in the mine
operations to report. The only place

This work is being extended to pros

work in the mine has been ore eX-

In the weeks work as reported
from the Consolidated, the raise be-
ing extended from the fourth to the
third level in the east orebody has
made Is feet from the level. Some
extremely high-grade ore has been
uncovered in the work. The distance
to be covered in the raise is about
40 feet on the slope of the vein,
between the levels, the vertical dis
lance being 112 feet.
The pump station on the fourth
level has been completed, and as

and lumber for the timbering of the
