The youngest and richest resources
Of zinc ore In the Occur d'Alene dis
trict has been developed and put in a
producing stage with milling equip
ment during the year on scale far
exceeding the shipping capacity of the
pioneer Success mine and is in the
same vicinity, short distance further
up Nine Mile creek, at the Interstate
Callahan property. This property
comprises a very extensive group Of
claims In the strike to the west of the
famous Hercules vein. 1t Is situated
almost entirely in the black mud states

has three main ore course develop
ments each of which show big COM
mercial ore resources.
The largest mineral resource now
exposed on the territory Of this COM
pany was opened through crosscut
tunnel started near the level of Nine
Mile creek, three miles above the Sue
cess mine. and driven north into the
steep mountain, where at point $500
feet in from the portal Of the tunnel,
zinc ore body was cut at vertical
depth Of 1900 feet below the apex and
J has since been driven on continuous
paying ore shoot carrying average
for distance Of 900 feet. In fact. this
great body of mineral has been stopped
continuously for that length and in
width. varying from to 40 feet and
from one to three floors high, and dur
ing the last days Of December this big
mineral channel was showing it's
greatest width and marked increase
from it's former low lead values at the
west face Of the drift and was still
going strong on its course and 40 feet
wide between steep pitching walls.
Wonderful Zinc Values.
This great shoot Of mineral has also
been cut at an intermediate level
known as the lower Callahan level, 400
feet vertically above, and has been
drifted on at that level several hum
dred feet, where it shows the same
rich zinc values The virtue of this
deposit Is the fact that 1t carries
very little iron sulphide and extremely
rich segregations Of clean zinc min
eral in places disclosing bands of clean
|sulpride ore up to SIEVE and eight feet
thick that will mine down SIS to so per
cent crude shipping value. The crest
Of this great ore body Is largely COW
cred with soil. The only portions OF
its apex exposed over its big ore re-
sources are on the original Callahan
ground and show little commercial ore
due to surface teaching. This Is evil
IDENTIFY one OF the virgin ore shoots OF
the district and is going to be one OF
the largest zinc ore producers from
present evidence Of It's lineal extent
and great width in the United States.
This property was equipped with a
mill Of 900 tons daily capacity early
in the summer that has since been
very successfully operated and has
made a large production Of high grade
zinc and lead-slver mineral as con-
centrates. and crude ore from short
picking belt The installation Of cleo
trio haulage at the mine in October
supplied the full capacity Of the mill
and brought up the monthly ship
ments to 1000 tons during the closing
months Of the year Of product rang
ing from 43 to SO per cent zinc with
an important by-product Of lead min
eral carrying 60 per cent lead and over
80 ounces Of silver per ton.
The Interstate vein presents the APP

that cuts the enclosing black Prichard

strike and the latter has decided

Callahan Vein Rich in Lead.
Parallel to this great zinc ore chan
mel, within 200 feet of it and rapidly
converging toward 1t going east, the
Callahan vein is an Independent ana
distinct assure that has been opened
to the S00-foot level by succession Of
crosscut tunnels driven in from the
Carbon creek side Of the mountain.
These levels have all been connected
and, in fact, this ore body has been
practically stopped through to the sur
face; 1t Is very much richer in lead
than the Interstate vein, in fact, car
rles its predominant values in lead
and silver. 1t occurred as a short,
pointed ore crest near the surface that
gradually expanded with each level as
the work progressed downward and
has made an ore shoot Of over 145 feet
long in the 500 level that Is still ex-
