West Greyrock-How the
Cora Miners Escaped.

One of the neatest and most compact
Of the medium sized plants of the
Butte district is that of the Greyrock,
one of the Butte & Boston properties.
This mine lies just north Of the Noun
tain Consolidated group of the Ana
conda company and within stones
throw of the Diamond mine hoist 1t
is connected with the West Greyrock,
which is usually regarded as a part
of the same mine, although it has it's
separate hoist.
The hoist at the West Greyrock is a
small one. and comparatively little
work is done there. The engine is of
about so horse power, and there are
two 60 horse power boilers. The shaft
is some 700 feet in depth The West
Greyrock is worked partly by the COM
pany and partly by leasers. 1t is about
on the line between the silver and cop
per belts, or more properly, it lies In
the zone where the two belts merge,
because it cannot be said that there
is any we'll defined boundary line. This
is illustrated by the circumstance that
at the West Greyrock a part of the
ore extracted is silver and part of 1t
copper

at more or less regular intervals That
is to say. they break down the ore and
get it all ready for hosting; and then
about once in the course of a couple
of weeks it is sent to the surface. The
hosting, it is scarcely necessary to
say, is done with single deck cages.
carrying what are usually termed one
ton cars.
The main work is, of course, done at
the Greyrock proper, where something
like 100 men are employed. This hoist
is equipped with a Gail Bumiler and
Unzicker engine, built at the Chicago
Iron works. 1t is remarkably rapid ia
its action and said to be capable of
working up to about $50 horse power.
The boiler plant consists of four sets
of 60 horse power boilers. mostly of the
Fras & Chalmers pattern.
There is also a Fraser & Cha liners
air compressor of about $50 horse
power with Nordberg gearing. 1t fur
nishes air to work the drills and a lit
tie for ventilation. That is a small
quantity of compressed air is used to
clear out the slopes and drifts after
blasting. Generally the air in the
mine is said to be good.
There is a very neat little % horse
power engine used to run the machine
ship and saws. The machine shop is
rather small, but apparently very well
appointed. The framing or carpenter
shop is kept in admirable order. and
is both a comfortable and comnodious
place. The well planked floor extends
away out in the yard, where the tim
Der is kept in stock.
In and about the hoist proper every
thing is in excellent condition. The
building Is snug and tight, affording
good shelter from the storms, and
cleanliness and order everywhere pre-
vail. The ore is hoisted with double
deck cages to an elevated platform.
perhaps a dozen feet above the collar
of the shaft. Thence it is run by
hand cars to the dump The track is
double and is securely covered and
housed in all the way to the dump, a
distance of probably 200 feet. The
waste passes on beyond to the great
waste dump, which stands so conspic-5
uous an object in that portion of the
district.
The copper water from this mine is
not saved. 1t is said to be fairly rich..
but the quantity is small, the mine be-
ing a dry one owing to it's elevation
