Gold bullion produced through the
application of the cyanide process of
extracting gold from it's ores has done
more in keeping the worlds gold sup
ply UP to the requirements, say scien-
lists. than all other causes. And al
though cyaniding is a comparatively
recent invention, it has resulted in
saving. during the past five years, over
one billion dollars worth of gold that
could not otherwise have been taken
from refractory ores.
So widespread is the use of the sys-
tenn that while the mining industry in
the United States has received unlim-
tied benefits therefrom, proportionately
good results have been achieved for
other famous gold mining sections, IN
cluding Rand in South Africa and the
great Cool Gardie gold fields of Aus
tralia Likewise there may be directly
attributed to the discovery Of this pro-
cess practically all of New Zealand's s
production to date of over $3.50, 000, 900
in gold bullion.
But of all gold camps that occupy
the close attention of the residents of
Southern California there is none that
has been benefited more by the appli-
cation of the cyanide process than
Searchlight, Nevada, for we find that
90 per cent of the values in the Search
light ores can be saved by combining
milling with this treatment.
100000 on the Dumps
The dumps in Searchlight are said to
contain at the present time nearly
81, 900, 900 of gold in the form of tall
ings, and just recently the mine own
ers have begun to install cyanide
plants, so as to turn this enormous
,amount of gold into the pockets of the
stockholders
Already three of Searchlight's pro-
ducing mines are equipped with CYAN
ide plants of limited capacity, the prop
critics being the Quartet, the Duplex
snd the Cyrus Noble; but a plant is
now being installed as large as the
three combined by the Searchlight
Mining and Milling company, with
capacity of $50 tons a day. Over
100000 Is being invested in machinery
by the company and the appurtenances
will include battery of two 70 horse
power boilers, using crude oil for fuel,
besides an array of large settling
tanks to be filled and emptied by pow
erful sediment pumps. The tailings
and shines, as they come from the
mill, pass directly into storage tanks.
and as everything will be handled by
machinery the treatment will cost less
than 81 a ton.
Report From the Camp
Senator H. E. Carter of the Search
light Mining & Milling company, who
has just returned from the camp, re-
ports that work is rapidly progressing
upon the new plant and that it should
be in full commission within less than
sixty days. Mr.. Carter states that the
bodies of mineral already disclosed in
the Searchlight mine are sufficient to
make 1t one of the greatest free-milling
gold propositions in the state of Ne
vada. He says that sufficient water
has been developed to treat any amount
of ore and he estimates that 80 per
cent extraction will be obtained by
use of new machinery.
Senator Carter says that mining men
who are watching the situation closely
in Searchlight assert that there never
was a camp where more ore has been
exposed for the amount of develop
ment done He points to the fact that
the andeStie dikeS running east to
west wherein the largest bodies of ore
have been found, give evidence of being
as ancient as any mineralized leads in
Nevada, and it is a fact that age of
mineraliZed formations eis Just as i'm
portant as age in wine, for the great
est ore bodies in the world have been
found where nature has generously left
exposed those formations which had
their inception In the aeons of the
past. This same condition is also true
of Tonopah, for in that camp it is
necessary to sink hundreds Of feet
the newer andesite Gaping in order
to reach the rich ore bodies that lie
imbedded in the ancient porphyry
Tonopah would not have been discov-
cred but for the appearance in but one
spot of the Mizpah vein, and likewise
Searchlight would still be an undiscov-
cred bonanza region had it not been
for the sharpness of an old prospector's
eyes in detecting the groupings of the
giant ledge on the Quartet.
But geologists say that, although
Searchlight's ores have been found at
the 1000 foot level, that this is but the
beginning of deep mining in the camp.
and they predict that the geological
showings give evidence that ore bodies
will go thousands of feet deeper. In
fact, they claim that the record of
Australia, where free milling gold has
been found at a depth of $500 feet, will
be equaled or eclipsed in Searchlight
