COUERD' 'ALENEM MINE
A MINE WITHIN THE CITY LIMITS
THAT is UNcoVERING LARGE
BODIES OF ORE IN ITS DEEP
WORKINGS.

Through the courtesy of VIM. F.
Gray, manager of the Coeur d. Alene
group Of mines on Academy hill, with.
in the limits of Central City, the
Observer mining reporter visited the
property Monday afternoon, and net
only inspected the surface improve
ments, but the several under ground
workings.
1t will be remembered that about
three short months ago, Mr.. Gray
came among us a stranger in
strange and unfa mil ar mining dis
trict, and assumed charge of a mine
that had lain idle for years. His
first act towards successful mining,
was to enlarge tie shaft house, and
place therein an additional 40 h. d.
horizontal boiler and ample coal bins,
all under the same roof. He also
overhauled the hosting and compress
that drives a ventilating fan at the
rate of 2,1OO revolutions per minute,
and then began tie repairing the
shaft that was found to be in
dilapidated condition, to the 700-foct
level, or bottom of shaft.
Your correspor dent found that in
former years the 70O-foot level had
been driven westerly a distance of
l25 feet, while that to the easterly
was 100 feet from shaft, each breast
showing streak of mixed concen-
trating and smelling ore from IS to
20 inches wide, while the back of
levels showed corresponding width.
Manager Gray is row engaged in
making two raises, tie one east from
Shaft about 80 feet is up some 35
feet, and las widsned out to feet
of concentrating ere that carries
several small streaks of smelling ore
of good grade. The raise west of
shaft, is now up some % feet, and
has widened to feet, with ore of
a corresponding grade. This raise,
as well as the brea st of drift, is be-
ing driven into unexplored ground.
and should this she OF extend to sur

mined therefrom. Manager Gray is
also driving a crosscut to the north
on this level. as feeders coming in
to drift, indicate that the hanging
wall is still to the north of drift.
On the 600-foot level. east of shaft
the floor of drift is of ore four feet
wide, assays from which return from
l " ozs. gold to $50 ozs. per ton.
From this level to the 400 level, the
ground is ali virgin, and from the ore
found in the bot ON of 400 level
would indicate that the ore bodies
are continuous the entire distance.
This level has been driven $50 feet
west and is the longest level in the
mine. The 200 foot level has been
driven west of shaft 100 feet, and
east 340-foot level SO feet, and this Is
where the good ore was mined in
early days. TIE maAager is badly
Handicapped in h s developments ow-
ing to the inefficiency of the compress
sor to furnish sufficient air and to
drive more drills. AT er we had made
an inspection of the mine and TIE
great quantities CT Gre blocked out, we
were astounded that mdne with
such quantities of ore in sight, with
In stones throw CT the principal
business streets of our city, should
have remained idle for so many years.
The great and crying need for plac-
ing this mine on sound financial
basis, in our judgement, is to place
electrical machinery thereon, install
compressor large enough to meet
all demands, and an up-to-date mill
at the dump, where all ores can be
dumped into the crusher room and
automatically distributed to their sew
eral departments, Il us saving heavy
transportation and milling charges.
Manager Gray is ably assisted in
his work by Foreman Gus Bolander.

a mill to handle its own ores, we
believe the Coeur d. Alene would
soon become one of the great gold
producers OF the camp.
