| One of the liveliest among the lesser
mines of the Butte copper district at
present is the Nipper. 1t is the prop
| erty of the Montana Ore Purchasing
company, and is located in the north
ern part of Butte, between the Never
| Sweat on the east and the Stuart on
| the west. For the past month or SO
| great activity has existed a the works,
| for the reason that all Of the buildings
| now enclosing the plant were either
| erected, reconstructed or enlarged by
| additions during that time. AS re-
suit. the works, being as yet implanted,
| look brand new, and being of ample
| size, give the mine an appearance of
Importance commensurate with its
| magnitude.
Among the new structures are the
| Office engine room, blacks NTH shop,
gallows frame, railroad ore bins and
| elevated ore tracks; and among the
buildings enlarged are the boiler room
| and the carpenter shop. The new ore
bins are large, and stand alongside the
railroad switch that passes the mine.
| The galloWs frame is lofty, and the ore
and waste are hoisted SO feet above
| the collar of the shaft, to where two
|
new ore bins respectively. The ore,
/ which was hauled to the smelter by
wagons before the new bins were built,
| is now shipped by rail.
| G. H. Robinson is superintendent of
the Nipper, having charge Of all of the
mines of the Montana Ore Purchasing
| company, and John Kane is the fore
man. The Nipper employs about 100
! men altogether, on the surface and
underground, and there are three en-
| gineers and about 20 topmen included
| in the force. The mine is equipped
with 12x14 cylinder engine of 100
horse power, manufactured by the
| Mine & Machinery Supply company Of
Denver, Col, and six T0-horse power
boilers built by the Standard foundry
Of Minneapolis. Two of the boilers
were added to the plant during the last
month. They are of large size. and
| rest upon heavy stone foundations. In
! addition to this the machinery OF the
| plant includes an Ingersoll air COM
pressor, capable Of working IS drills,
| and two pumps, the latter being locat-
ed on the 800 and 500-foot levels. The
shaft has a depth of 500 feet, and is
| divided into two compartments. One
of these is used for hosting and the
| other for repairing. The latter also lc-
commodities the air and pump columns
| The cage in the hosting shaft has
| double deck, and a one-inch round wire
cable Is used in connection with it. The
| Nipper has five exits, and underground
! connections with the Stuart and Never
| Sweat. 80 .''
| Besides the ore and the waste being
mined at the Nipper, ore which was
| piled UP in a dump near the shaft in
| the past is being hauled by means of
| a winch from where it lies up an in
! clined tramwayn, to- the collar of the
waited tracks above and dumped into
| the new ore bins. A new railroad
switch track is now under construc-
| ton. All this work adds considerably
to the regular operations on the sur
face and makes the Nipper a bustling
place. The Nipper is one of the best
of the NJ. o. P. properties.
The Cora, another mine belonging
| to the Montana Ore Purchasing COM
pany, is located on the border line of
the Butte copper district and the gold
| and silver bearing region that extends
to the northward. It is in the eastern
part of VAUDEVILLE and about 200
| yards northwest of the Gray Rock.
While it is not one of the largest of
the Heinze properties, 1t is a valuable
mine and has promising future. Its
| workings are comparatively shallow as
yet, and the presumption is that it will
| augment in value as depth Is reached
in the exploration of its lodges. d.
B. Vincent is foreman of the Cora,
and about 40 men are employed at the
| mine.
The machinery plant at the Cora
consists of a 12x14 cylinder Ottumwa
engine of 50-horse power, four 50-horse
| power boilers, two of which only are
in use at present, five-drill air COM
/ pressor and two pumps, one on the 900
and one on the 600 level The shaft Is
down 500 feet, has two compartments
| and is provided with a single-deck
| cage and a one-inch round wire rope.
The air compressor operates Ingersoll
and Rand drills. and pumping is done
| every other day.
The buildings housing the Cora plant
are also new, the old works having
| burned down on the 18th of last Sep
TENDER. At that time all the buildings
were burned except the ore bins. Like
that at the Nipper, the gallows frame
| at the Cora is not covered, and it also
| escaped the fire. 1t was threatened,
| however, and the men at work under
ground made their escape from the
mine by way of the Gray Rock. They
made their way to the latter mine by
means Of a connecting drift, and were
hoisted to the surface through its
shaft The fire resulted accidentally,
| through the ignition of coal oil which
had leaked on the ground from a, coal
| oil tank that stood in the back part
| of the boiler room. The tank was 10
feet from the furnaces, but a hot sol
dering iron thrown on the ground by
a workman repairing fiue set the oil
on the ground aight, and it carried a
train of fire to the tank. The loss
was three or four thousand dollars.
The new buildings, erected since the
fire, are rather larger than those burn
ed. Besides the shaft now in use there
is an old shaft on the Cora, a hundred
| yards to the east. 1t was abandoned
II or Is years ago by the owners of the
property then, and has not been used
since. But the NJ. O.. P. company Is
now considering plans to resume the
use of it and sink to the 1000 level
1t is down 500 feet, and is connected
with the shaft in use on the 800 level
In little while another connection
with it will be made on the 600 level
The workings on that level are under
it, and a raise will connect with it al
the bottom. A great deal of valuable
gold ore was mined from the neighbor-
hood of the $50 level of the mine and
extracted through the old shaft years
ago. Much development work is going
on at the Cora, and considerable tim.
