RlTTLEsNAKE AND KEYSTONE
Construction Of New Tybo Rail-
road Will Bring These Mining
Districts Into Production
(By James f. O'Brien)

reiuvenated as result of the con-
struction of the new railroad which
the Louisiana Consolidated Mining
Company is to build in connection
with its Tybo mine operations is that
where the Rattlesnake mine is To-
Gated. seven miles north of Tybo.
There has been little doing there in
recent years. largely as result of ex-
cessive freight and treatment costs.
but partly due no doubt to the fact
that the owners of the principal
property had their time taken up
with larger interests.
The Rattlesnake group. which con-
sists of twenty-six claims. is owned
by John w. Brock, former president
of the Tonopah Mining Company of
Nevada. Clyde Heller, president of
the Belmont and Jim Butler COM
panies of Tonopah. the White Invest
ment Company, Frank Keith and
others who are prominent in the min
ing world.
While the Rattlesnake was being
developed, the mine was examined
by A. A. Blow, at that time one of
the most sought after mining engin-
eers. The report of Mr.. Blow was
favorable and he stated that the ore
bodies of the Rattlesnake, and the
formation generally, were more like
the big mines of Chile than any he
had seen in America. He laid out a
plan of development which included
the sinking of four shafts. The
greatest depth attained, however.
was about $50 feet, when the water
bothered considerably and operations
were suspended.
The best ore that came from the
Rattlesnake was found in chimney
deposit on the Ophir claim. This
was very rich and showed consider
able native silver. In spite of the
expensive wagon haul to the railroad
the richest ore was shipped as it was
mined, but the balance, which goes
from $50 to $75 per ton, is still on
the dump. Worth L. Wiswall is in
charge of the property and is also
postmaster at Keystone, which is the
post Office of that section.
The Keystone Mountain group of
IA claims lies close to the Rattlesnake
group. 1t is owned principally by
Col. Thos. L. Wiswall and his son.
Worth, and the showings are such as
to warrant extensive developments
in their belief. Col. Wiswsll is well
known. especially to the older genera
ton Of mining men. as he was pio-
neer in introducing the cyanide treat
ment of ores in this country.
There is at least one vein on every
claim of the Keystone group. and
with the exception of one they are all
in the lime Very little gold is found
in the ores occurring in the lime, but
in the vein on a contact between lime
and porphyry ore has been found
which assayed as high as $25 in gold.
The veins vary in width from one to
four feet.
The Louisiana Consolidated Min
ing Company continues to make
splendid progress in its operations at
the Tybo mine. The large number
OF surface improvements take time.
but they are necessary in view of the
assurance of a long life to the mine.
In this connection it will be apropos
to quote from an article which ap-
peared in the White Pine News un-
der date of April 10Th. 1t appeared
under the head. "Tybo Is Coming
Camp" and was evidently written
by one who is familiar with the camp
from its earliest development. The
quotation follows:
With reference to the historic
camps. the resources of the Tybo
district alone will probably not be
exhausted within the next 25 years.
