LODE TO BE OPENED
Calumet & Hecla Go. May Develop
a Great Mine on the Kearsarge
Amygdaloid.
Intense Interest Has Been Aroused
in Preparations and Plants
at Calumet.

Special to The journal.
Calumet, Mich, Aug. 15.-Active prepa-
rations for the opening ofthe Kearsarge
amygdaloid lode have been started by tho
Calumet and Hecla Mining company. A
shaft will be sunk about 1900 feet south
Of "A" shaft Of the Centennial mine. The
overburden Is about forty feet thick at
that point, and it is understood that the
shaft will be carried into the ledge to a
depth sufficient to determine the qualities
of the lode.
While the opening Of the Kearsarge
amygdaloid on the Calumet and Hecla
property may be considered merely an
exploration until the value Of the forma-
ton has been more fully ascertained, it
has aroused intense interest, as the move
may result in the development of a mine
furnishing employment to 1000 to 5000
men. Preliminary to the opening Of the
mine on the Osceola lode, now idle, it was
very thoroly tested by means of crosscuts
before any shafts were sunk. The same
process was followed with reference to
the Kearsarge amygdaloid, which was
tapped at two different points by cross.
cuts from the openings on the Osceola
lode. The Calumet and Hecla carries the
outcrop Of the Kearsarge lode and there
is room for several shafts.
The Kearsarge amygdaloid lies to the
eastward of the Calumet and Osceola
lodes. 1t Is opened at the Mohawk, VOL
VERNE, -Kearsarge and South Kearsarge
mines, and continuous milling operations
have demonstrated its richness at those
points The Centennial and Ahmeek are
developing 1t and the showing at both
properties is very good. The mines opened
on this formation are shipping upwards
OF 1900 tons Of rock daily, and it is
equally as important to the north range
as the Baltic lode IS to the south range.
Mass and Barrel Copper.
The Champion mine forwarded a car
load of mass and barrel copper to the
Portage lake shelters this week. The
output Of this form Of the metal was
ninety-1ve tons last month. The metal
is in Its native form and goes directly to
the smelters without stamping, returning

1t is no longer denied that the Tama-

such great depth, is large; and the rock
does not contain as much copper as thai
from some Of the amygdaloid mines of the
district.
