PEARL MINING DISTRICT.
Pearl Mine. Belonging in swsde Group
Of claims-Immense Low Grade Prop
osition ~sonbright. Of Illinois Copper
Co.

The Pearl mine, located about
one and one-half miles south of
Pearl, Colo, is one of the largest
low grade propositions in this dis
trict. This mine is owned by
Eastern and Colorado parties and
has a good strong company back
ing it. The officers are: Arthur
H.. Chetlain, Judge Supreme
court, Chicago, Chicago, Presi-
dent; Cyrus Mark, merchant, Car
roll, la; vice-president, Robert
l.. Coburn. cashier LIST Natl Bank
Carroll, Ia, Secretary & treasur-
er; and Porter b. Coolidge, Raw
Inns, Wyo., attorney and general
manager.
This property has a large shaft
house, so h. p. boiler 10x14 hoist,
pump, and is equipped in every
way to do an immense amount of
development work. The work
done up to the present time con-
sists of n shaft 2S5 feet in depth,
two cross-cuts, one at the $50 foot
level, which is 60 feet in length, and
a cross cut and drift at the bottom
of TIE shaft. This cross cut is 30
feet in length, with a % foot drift
on the vein all of which is in ore.
The vein matter is a schist, and is
well mineralized, running from 6
to III per cent. copper and is an
immense body, the extent of which
has not been determined, as both
walls haoe not been reached as
yet.
f. j. Riley, formerly superin-
tendent of the Ferris Haggarty,
has charge of the work, and is do
ing some excellent development
work. The shaft is double COM
partment and is we'll timbered
throughout.
In talking with FL. C. Beeler,
state geologist for Wyoming, con-
corning the Swede, and other low
grade properties, he expressed the
opinion that a good low grade
copper mine was as good as the
best, as the high grade PROPOSE
tions eventually turned into low
grade, and the low grade proper
ties could always be depended up
on to keep up their output.
The Swede is an excellent prop
osition and is one of the strong
mines in this district. The CON-
pany have ample funds with
which to push development work
and will have the Swede among
the first shippers on the compile
ton of the smelter and concentrat-
ing plant which is to be built in
Pearl this spring. G. O. Films, of
this place, is a heavy stakeholder
in the Swede and has unbounded
faith in the ultimate outcome of
the Swede, and he is well backed
in his confidence by the showing
on that property.
Another good property this
district is the Bonbright, belong
ing to the Illinois Copper Mining
Co, which is located about four
miles north of Pearl, in Wyoming.
This company owns a group of
claims, but outside of the assess
meut most of the work has been
done On the Bonbright. Two
shafts have been sunk on this
claim, one of which is so and the
other 80 feet in depth, with a IA
foot drift at the bottom of the 30
foot shaft. Both shafts have a
good lead, the so foot, or what is
known as the upper shaft, having
a 3 foot vein Of high grade copper
ere and the lower shaft a y foot,
strong, vein. The ore taken from
these leads cannot be discounted
any place in the entire country
and it is a question of develop
ment work to put the property
among the shippers. Work has
been suspended the past few
months on account of a lack of
funds, but will he resumed some
time during the present month
and continued all winter. The
shafts are nearly full of water at
