New Era Da~ns For Humbold. coun
~. silver Camp With Starting
Of ,oO.ron Plan.

Rochester started on its new era of
LIE as a mining camp today wher. at
To- clock. the $4,000 reduction plant
began operation on ore from the Codd
and Big Four leases. says the Ga.
zette.
A A. Codd, who came In from Roch-
ester today, said he believed the mill
would prove capable Of handling more
than Its rated 100 tons Of ore every "a
hours. It was tried out yesterday for
q few hours and fulfilled all the ex-
pectations OF its builders.
1t 10 estimated that the properties
at Rochester have 10000 tons of ore
blocked out, waiting for the mill. or
this amount the Codd lease alone has
$4,000 tons. Through its new trans
portation tunnel, built in conjunction
with the Big Four lease, 1t has cut IL
TO IA feet Of ore on the 610-foot level,
and 1t has the privilege OF mining to a
depth OF 100 feet below that point. The
Cod lease has contracts calling for
the milling Of at least 40 tons of ore
daily for the next 10 months. and II
ing that time It is expected that 1OO,-
600 tons OF ore in addition to that
milled will be laid on the dump for
milling at a later date.
Long Tunnel Planned.
L. A. Friedman. who has large inter
ests In tho Parent company, the
Rochester MIrEs company, and who
has been tn moving spiri. in bring
ing about tn new era in Rochester.
has announced positively, Mr.. Codd
says, that within a few days a tunnel
OF 5000 feet will be started at the
base Of Mcneil Hill to cut the main
vein at a depth of LOO feet.
In addition to the big investment in
the mill and equipment, there is an in
vestment Of s250.00O in the new power
line from Lahontan. This was con-
structed by the Nevada Valleys Power
company to which a long lease on the
power plant was granted by the gov
eminent on favorable vote Of the
Truckee-Carson project water users.
There Is an investment Of $4,000 in
the Codd railroad, the Nevada Short
Line and an investment by the par
m company Of $4,000 in a tramway
that Is now delivering ore to the mill
by gravity.
AlLslimes Process.
The new mill has 10 stamps weigh
ing 1850 pounds each, or a third more
than the ordinary stamp. In addition,
there are two tube mills and a series
OF 10 cyanide tanks. The all-slimes
process of treatment Is used. The ore
proves very amenable to handling,
crushing readily. It is reduced to
such %fineness that 1t will pass through
a 2OO-mesh screen. In the stamp mill
and in the tube mills, the ore Is under
the influence Of the cyanide solution.
In the first FIVE tanks II is further
agitated to insure Liberation of all the
values into the solution, and in the
last five the decantation prc cess is
used until, from the last tank, the So
luton m of clear to flow over
zinc shavings for precipitation of
precious metal contained. Water for
the mill Is brought from Weaver can
yon and is proving twice as much
as needed.
Ore to Average s15.
ut Is expected that the ore milled
will average SIS a ton," said Mr.. Codd.
with the increase in depth, the ore
has widened out. At our lowest level,
10 feet Of 1t averages $3.50 a ton. All
dead work has been done and all work
~henceforth in the Codd lease will be
In ore. The r reserves and posi-
bilities at Rochester are such as to
fully justify tue consideration now be-
ing given by the parent company to
the question Of doubling the capacity
Of the new mill that started today, The
future in Rochester looks very
bright"
