The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1920-11-11

~ mine is closed down so far as
~ production is concerned. the
Consolidated Interstate Gala
han Mining company is engaged in
highly interesting underground de-
velopment in no less than three
places and the results in each one of
them will have an important bearing
upon the future operations of the
company. The activity of the Inter
state Callahan at this time is strik-
inely significant of the outlook for
mining in this district from the
standpoint of the company. Although
forced to suspend production. the
company is evidently looking forward
with confidence to better days for the
zinc and lead mining industry and is
preparing to take advantage of the
improved conditions when they ar
rive It is probable when the com
pany does resume production the ore
reserves in the Interstate Callahan
proper will be largely increased and
new source of ore supply will have
been opened in the Nipsic which is
being developed through the Inter
state Callahan workings. At the same
time work is being pushed at the Chi
cago- Boston and it is altogether prob
able that it will enter the list of pro-
ducers next spring or summer.
Vein on 10th Level.
Upon the extension of the main In
terstate- Callahan shaft to the No. 10
level. a crosscut was started to the
vein. Later a diamond drill was used
to locate the vein, which appears to
he split on this level, the two sec
tions being about 80 feet apart. Fol-
lowing this disclosure with the dia
mond drill. the crosscut followed the
hole and has now cut the first vein.
which shows y feet of low grade ore.
The crosscut apparently passed
through the end of the ore shoot as
indicated by the position of the ore
body in the levels above. and drifting
has now been started which will prove
it's value and extent. The crosscut
will also be extended to the other
branch of the vein which the core of
the diamond drill showed to carry
better grade of ore than the first. On
the No level the ore body has been
proved to be fully equal in grade and
size to the showing above with the
advantage that there is decidedly
more lead while the formation and
character of the vein are identically
the same. These conditions hold good .
on No. 10 as far as explored which
iustifies the expectation that there
will be no diminution in the value and
quantity of ore. The No. 10 level is
1850 feet below the main tunnel level
When these favorable conditions have
been proved. the shaft will be sunk
200 feet further.
Nipsic Crosscut.
Work is also going forward in the
Nipsic crosscut and it was stated by
Mr.. Newton general manager of the
Interstate Callahan. that the vein will
be reached in about 40 feet. A cross e
cut has been run from the No. level
across the Silver state into the Nip
sic ground. From the face of the
crosscut a diamond drill penetrated
the Nipsic vein after running about
400 feet the core indicating about six
feet of lead-silv ore. This diamond
drill work has been followed by the
extension of the crosscut, which as {
stated above. is now within 40 feet of
the vein. Considering the disclosure
made by the diamond drill in connec-
ton with the fact that the tunnel on s
the Nipsic vein 1000 feet above has I
developed a very promising shoot of
lead-silv ore. the conclusion fol-
lows that the opening of the vein on
this deep level will make an import
ant addition to the available resources
of the Interstate Callahan. ]
Chicago Boston crosscut.
In addition to these important de- e.
at the Interstate Callahan E
mine. the company has 16 men en- {
ployed at the Chicago Boston driving L
a crosscut from the bottom of the {
4OO-foot shaft Last Tuesday Mr. G
Newton expressed the opinion that y
the vein would be reached in about 80 I
feet. although it is probable that this 7
figure may vary one way or the other, t
as the DEVELOPMENT on the levels 7
above is not sufficient to make a close G
regarding the dip. 1t is safe {
to say that no mining development in c
the district is being watched with r
