FINE PROGRESS
At THE G|ROUX
PERMANENT HOSTING PLANT
WILL BE GREATEST IN DIS
TRICT AND ONE OF THE BIG
GEST IN THE WORLD.

At the Giroux Consolidated the
same marked activity which has
characterized the operations for the
past year Is still In evidence; and
daily are they nearing the goal for
which they started a year ago
the development of and produc-
tion from the rich orebody of the
Alpha shaft In the limestone. When
the big pumps are installed at the
IL foot mark in the five-compart-
ment Giroux shaft, they will begin
the work of prosecuting to the east
to the orebody; and from present
indications this should be during
the coming month.
The station at the 1,200 has been
cut. and they are now reinforcing
Ii with concrete. One end and
nearly one side of the immense cav
ern has been covered with the
concrete; there remains the other
end and side and the dome.
The station is 125 feet in leEgth and
25 feet in width. and will house
two pumps; one of a capacity of l.
200 gallons per minute and the
second with just one-half that
capacity. A third pump with
capacity for handling 500 gallons
minute is on the ground. but this is
intended for installation at a great
.er depth in the Giroux shaft.
There Is plenty OF water In the
Alpha shaft, with which the Gi-
roux is connected at the 1000 foot
Level by crosseut, 500 feet long. So
much Is there that II was long ago
found impractieable to handle the
rich ore from that opening: hence
the great five compartment shaft TO
the west, which is now the working
shaft for all the country in that
part OF the estate of the Giroux
Consolidated Mines. The upraise
for the five compartment shaft from
the 1000 foot level was made in dry
ground, and they did not get any
water until close to the 1900; and
then but a small amount. With the
two pumps installed the manage
ment will be ready to handle any
kind OF a flow and the more they get
the better they will like it, for they
have hopes of developing suffi-.
cient supply to run their own reduc-
tion works and treating their ore on
their own ground.
oOIh Ou the nOlSllIlB
plant is progressing with rapidity.
The location of this plant is about
400 feet to the west and south of
the big shaft Already the ground
has been exyayated for the eight
boilers which are on the ground.
and the excavation for the engines
Is nearly finished. The coming week
Will doubtless see the commence
ment of the concrete foundation
for the structure. This will be the
greatest plant in the district and
one OF the biggest in the copper
mining world. The engines, two in
number, will have behind them
eight horizontal tubular boilers,
each of $50 horse power. One of
the engines is Duplex, 26x4S in
ehes, direct acting, with a ten foot
drum; ana the other Is a 20x4S
geared engine. with ten foot
drum. Inc first will handle two
hye-ton skips; and the second the
timber cage and the pumps.
The present wooden gallows frame
will be supplanted by a steel head
frame, rs feet In height, which is
already on the grounds. This will
be put In place without at all inter-
fering with the work of the shaft.
or the driving of the crosscut. 1t is
mooted that the counterpart of the
Gfroux five compartment shaft is to
be put down on the Rickard Ely.
This will probably be done later,
for the survey has been made as
has that for the continuation of the
three miles of trackage within the
lines of the Giroux Consolidated.
Perhaps the coming of President
Cole may have the effect of precipita-
ting this work
Ii Is now evident ..-... the first ore
to be produced will be from the
wonderful Alpha orebody In the
lime. The general average of this is
better than 20 per cent, while in a
winZe which Is down $50 feet from
the 1000 level. is all in ore the
MAJOR portion of which is native
copper. This body of ore. so far
as II has been explored is suffi-
cient In itself to make the Giroux
Consolidated one of the biggest OF
the copper producers; but 1t is only
part of the mines great ore res
eryes which amount to several mil
lion tons.
In Old Glory is another mine in
the limestone. and the Morris and
two Brooks shafts are In the porp-
hyry. The exploration work done
by these shafts has been supple
mented by churn drills during the
past year; and the results have
been more than satisfactory to the
management and to the stockholders.
The work done In the porphyry has
emphasized the presece of ore
enough and of sufficient value to
warrant steam shovel pit propo-
sition which would be of greater
area than that OF the steam shovel
