ORE TREATMENT
Of WHITE CAPS
PROCESS SAID TO BE SUCCESS
Full WITH MORE EQUIP
MENT

frequently asked by those who r
interested in the White Caps mine
and are assiduously following devel-
opments in every phase of the en-
terprise. is: HAS the mill process
proved a success"
The question was practically an
swered in the affirmative about two
weeks ago when the first bar of bull
lion extracted under the new method
of treatment was turned out by the
company and exhibited at the Ne
vada First National bank of Tono-
pah; yet, Notwithstanding the fact
that the credulous were given visual
proof in the shape of a big gold bar,
many inquiries were made of the Of
ficials of the company as to whether
a complete recovery had been made
of the gold contained in the precipi-
tates that were forwarded to the To-
nopah Extension mill for melting.
Such inquiries ELECTED from the
management the frank statement
that the first bar of bullion was the
result of only a portion of the pre-
cipitates extracted by the mill and
was largely in the nature of a final
test to prove beyond the question of
a doubt that the extraction process
could be carried through all the
various stages in the mill and ter
inmate in the production of the
yellow metal.
The management. when giving out
the above statement, explained that
the company was installing addition,
/ al equipment in the mill, to increase
it's capacity, effect a quicker and
more complete recovery of the gold
values, and add to the general eff
~ficiency of the mill as a whole, and
that until such equipment was in
stalled it was not the intention to
rush the tonnages through the mill.
AS a matter of fact, the substitu-
ton and installation of the various
new mechanical devices interfered
to only a slight degree with the
passage of the ore through the mill,
and it has been working steadily,
though not at maximum capacity,
since first being turned over.
The equipment consists of a Dorr
classifier, to separate the shines
! from the sands, enabling the mill to
recover the gold values more thor
oughly and quickly in the teaching
process; a new Buffers filter, which
has just been received at the mine
and is now being set up; an endless
chain bucket conveyor to elevate the
ore from where it issues out of the
rooster, and a long 0eIt cOnveyor to
carry the classified ore to the tanks.
These latter improvements replace
the former system of handling the
roasted ore by mean of cars, which.
after being loaded at the furnace,
had to be pushed by hand to the
mill elevator, hoisted above the
tanks and sen along a railway 10

CT the belt and bucket conveyorS,
Which have just been placed IN m
mission, means the %effecting of
great economies in the handling IF
the ores, thus tending to love- the
cost o. treatment below the figures
previously authorized, namely. about
81 pei ton.
The officials of the company, hav-
ing demonstrated to their entire sat
isfaction the feasibility of convert
ing the refractory ores into gold,
expressed their confidence to inquir-
ers thai so soon as the additional
equipment had been completely in
stalled in the mill, it would quickly
respond by showing an increasing
number of gold bars at the bi-weekly
melts, until the maximum output
was attained. With the mill rapid
ly getting in its completed form, it
is thought that the next 80 days will
see the production of gold bars in
regular quantities.
There is no question as to the i'm
mensity of the ore reserves in the
mine, which are sufficient to last
for years, even though there will be
shortly running through the mill the
greatest possible tonnage-between
IT'S and 200 tons per day. Without
taking into consideration the posi-
bilities that exist at depth. which
competent and conservative engi-
neers estimate will be between 1900
and 1000 feet, and to which dis
lance vertically the ~orebodies will
reach before e~ncountering the under
lying formation, alaskite, the COM
pany has enough ore in sight in the
