Newhouse Mines and Smelters

ing exceedingly economical in the con-
sumption of coal. A 1000 cubic feet per-
installed.
All of this steam driven machinery has
now been superseded by electrically
driven machinery, which is operated by
Power company on Beaver creek, some
forty-five miles from the mine and trans
mitted under voltage of 5000 TO the
mining companys transformers.
The mill is connected with the mine by
four and one-half miles of standard gauge
track on which is operated a 65-ton en-
CINE and a train of five Seton self-dump-
ing cars. The miners are all boarded al
the town of Newhouse and are carried TO
and from the mine in the company's pas
Senger cars
The portal OF the tunnel is 615 feet above
the mill and is driven for over a mile
into the mountain before striking the Gao
tus ore bodies on the 600 level of the
shaft. The property was originally owned
and operated by a French company, which
did some development work near the sur
face, and erected concentrating mill and
a small smelter both of which were
doomed TO failure by reason of the lack
of any water supply. The French COM
pany. however. had done sufficient work
TO show that the property had merit and
| that, if worked on a large scale and with
proper appliances. a big copper mine
could be developed.
In 1908 the property was taken up by
| Mr. Newhouse and active development
new shaft was started and sunk TO the
6OO-fOot level Drifting, to make connec-
| ton with the tunnel, which was then
| advancing toward the shaft, was started
| in order to hasten the connection In
March, 1895, the mill was started and 1t
has been in continuous operation to the
present time.
In the early part of 1907. while devel-
] opment work on the 400-foot level was
being carried on, large body or nigh
grade copper ore was found. Upon de-

| large for such rich ore. 1t was followed
Up to the 300-foOt level and was subse-
quently traced down TO the 6O0-fOot level
Several square sets .of 20 per cent ore
were left under the sills of the 600-foot
| level and there is no doubt that the
shoot of high grade viii be found on the
! lower levels. The high grade ore cam7 as
an unexpected addition to the company
| assets, and. as its discovery was made
during the exceptionally high copper mar
ket, il added very largely TO the com
pahy's output. During the year 1907 the
company produced over 9,OOo,OI0 pounds or
copper. one-third of which came from ore
averaging about IS per cent copper.
The high grade shoots. however, while
adding greatly TO the output of copper,
must not be considered the company's
chief asset. This consists of the immense
bodies of concentrating ore which were
found outcropping on the surface and
were subsequently followed down to the
a00-foot level About 100000 tons of ore
are known to lie between the surface and
the lowest developed level. and there are
still great possibilities for finding new
ore bodies, as the lower levels especially
are not yet properly developed.
The ore body on the surface is. roughly,
about 1000 feet long by an average of 100
feet wide. In places the width is as
much as $50 feet Large glory holes"
were started near the surface and a steam
shovel. which did exceedingly good work,
was installed. The glory hole" work
was very successful and many thousands
of tons of cheap ore were run into the
chutes by this method. Latterly. however.
these open pits having attained depth
of 1J0 feet. were found TO be too danger
granite walls. which upon exposure TO the
atmosphere rapidly disintegrated and
kent continually sliding rocks and debris
toward the bottom of the pits They were
therefore abandoned in favor of under
ground mining
DEVELOPMENT on the 400 and 500 levels
proved the presence of another hitherto
unsupported ore body, which is separat-
ed from the original one by a horse of
waste. On the COO level this waste is
sufficiently mineralized 20 be considered
as ore. while on the 100 level il appears
as waste again. and the two ore bodies
are distinct from one another.
Up to the spring of this year the square
set method has been entirely used for
underground mining. but this is now
| is yielding very satisfactory results. The
future outlook for the mine is very hope
full The known ore bodies are large
and of fair grade. development work is
being continuously carried on. new bod
! les OF ore hitherto not included in the
ore reserves are being developed and have
proved 10 be Of profitable grade. while
/ the equipment of the mine is good and
capable of handling a thousand tons a
day.
