To DEVELOP OsCEoLA LODE
e. n III. Preparing to Sink Three
Shafts OH the AmygdalOid vein.

The Calumet Il Hecla began the
preliminary work Monday for three
new shafts to be sunk on the Osceola
/ amygdaloid vein. As is generally
known, remarks the copper country
correspondent of the Marquette
Mining Journal, this mine has been
developed, and has earned it's
fabulous profits altogether from the
Calumet conglomerate lode. This
lode extends Some distance north
and south OF the property, but the
Centennial mine, adjoining on the
north, and the Osceola, which ADULTS
on the southern line, have never
been able to get enough copper out
OF the Calumet conglomerate in their
ground to make it pay. The Calu-
met Il Hecla, however, has the
Osceola amygdaloid underlying its
entire property, the amygdaloid
dipping under the conglomerote and
outcropping about six hundred feet
to the eastward of richer lense.
Drifts have been driven from the
underground workings on the con
glomerate to the amygdaloid belt,
lying to the eastward at three diff
ferent points, and at each place cut
the OSceola lode was found rich in
material
1t has been a surprise to many
not acquainted with the methods
and management of the Calumet and
Hecla that no attempt has ever been
made to develop the great amygda-
loid belt, which is fully as rich as
in the territory Of the Osceola and
from which the latter named mine
has been able to pay over two mil
lion dollars in profits. The policy
of this great mine, however, is con
sistent one, and with such magnifi-
cent reserves of mineral ground as
are possessed on the conglomerate
lode, it had not been deemed wise TO
attempt opening an additional lode
carrying much smaller amount of
copper until the present time. The
work was begun Monday of remov-
ing the buildings which occupy the
site of one of the three projected
shafts, and the actual work of sink
ing will be started in short time.
The shafts will all follow the incline
of the lode, and will be in copper
bearing ground almost from the |
start, and consequently will in all
pay for their sinking by
the copper taken from the ground
they pass through.
The work OF sinking the three
shaft and erecting tt" necegsm 2
engine houses for their operation
will probably require couple of
years, for the owners Of this big |
have ground opened ahead !
for more than ten years production
of copper aud need be in no hurry |
about opening more territory. 1t |
does not necessarily follow that the |
mine will increase its output because
of the opening of the amygdaloid
vein. 1t is fact that Nos. 10 and
II shafts, near the southern bound
airy of the property, were opened
for ten years before they began pro-
ducing copper, and would have re-
mained unused for longer time but
for the fires of 1887, which rendered
the older workings of the mine in
accessible for u number of months,
and large forces of miners were put
at work on the two shafts named
with its older workings protected
from the ravages of fire by care
fully planned system of firo-alarms,
Iire-doors and pipe lines carrying
water for fire protection, and with /
It's vertical Red Jacket shaft, equal
TO six ordinary mining shafts, near
y ready for production upon an
scale whenever it is de-
sired to bring the copper out of that
part of the property, even more
serious fire than is likely to occur
under almost any circumstances
could scarcely operate to seriously |
hamper the regular production of
The mine, and it may be many years
before the amygdaloid shafts now
being begun will be required to
furnish their quota
