NEW METHODS At
ROCHESTER MINE
LATEST AND MOST APPROVED
PROCESSES ARE TO BE
EMPLOYED

A revolution in mining methods
on Rochester hill is about to take
place with the approach Of the
Friedman tunnel of the Rochester
Mines company to the veins OF the
Crown Point claim. In the future
ore will move from its bed in the
rein through every stage from the
mine to the bullion bar by gravity.
In the meantime the cost of produc-
ton and milling will be reduced to
a minimum.
The Friedman adit will tap the
veins of the hill at a depth OF 12U0
feet giving backs of 500 feet up to
the present workings at the 400
level. The bore is now in 40
feet and is approaching a zone which
indicates the immediate presence OF
the veins that have been sought. 1t
is probable that an announcement
of big discoveries will be possible
before the end of the week.
Under present conditions mining
is expensive below the 800 level be
cause of the necessity of hosting
the ore to the 30O-foot drifts from
whence it is taken to the transpor-
tation tunnel and carried down the
tramway. A great portion of the
ore that is now being milled and
stored in old slopes comes from
above the 300 level, but although
this material is being handled ex-
reditiously and cheaply, future costs
for mining and milling will be
brought down to between 81 and IS
Il ton according to figures given out
by l.. A. Friedman. president of the
Rochester Mines company.
To prepare for the new regime
extraordinary preparations are GO
ing forward on Rochester hill look
ing to a Capitalization of equipmenv
and the adjustment of all unneces-
mine operations.
Two old compressors from the
Big Four and the Four ] blocks for
merly operated by leasers, have
been brought down the hill to the
portal of the Friedman tunnel.
lhOoO oiO pOAhS oOt up w - " W 49,
Hilary power to the new Sullivan
compressor now in commission, and
from this central point will furnish
air for all the workings on the
mountain. including air furnished to
other properties at either end of
the Rochester Mines. A complete
machine house and blacksmith shop
has been erected and equipped with
/ air-driven drill sharpened and fur
paces. Every MODERN appliance il
being installed to insure economi-
cal mining.
When stopping begins in the drifts
from the Friedman tunnel level the
present tramway at the mouth OF
the transportation tunnel will prob
ably go entirely out of commission
and be cast aside. With it will pass
the big ore bins and mine structures
hat have served their time in the
earlier development of Rochester
march of progress. The transition
marks the passing of the old order
when Rochester was spoken of as a
possible camp. and gives way OF an
established property that in future
will be discussed as one of the great
mines of the west.
Ore is now being broken down at
the rate of more than 800 tons a
day. During the past month the
mill has been handling lis tons a
Cay and the balance is being stored
in the old slopes. Under the present
rate of treatment and figuring the
ore at an average value of SIS
a ton. the company is making a net
earning of 100000 a month. In
spite of the heavy development ex-
pense involved in the driving of the
Friedman tunnel and the installation
Of new equipment together with the
payments on the mill, there is every
possibility that Rochester Mines
company will enter the ranks of divi-
dend payers NEUTRALITY-SUSPICIOUS..
