THE CALLAHAN SHAFT
DOWN TO 10TH LEVEL
Crosscut is Now Be-
ing Run to the
Vein
MUCH ORE ON 9th LEVEL
Depth of Shaft, 1850 Feet
Increase in Lead and All
Conditions Favorable

TVHE MAIN shaft of the Inter
/ state-Callahan mine is now
down to the No 10 level, which
is 1850 feet below No. or the
main working tunnel. This point is
practically on a level with the tunnel
started several years ago by the COM
pany from Beaver creek, the purpose
at that time being understood 10 make
that the main outlet the plan includ-
ing the building of mill at Enaville,
where the company secured a desir-
able millsite. The large investments
lin mine plant mill, tramways and
buildings on the Nine Mile side ind-
cate that the company has perman-
emily abandoned the Beaver creek
plan, although in the course of devel-
opng its large holdings which extend
down to Beaver creek, it is possible
the plan might eventually be carried
out.
Ore Holds Good With Depth.
AS in the case of all big mines of
the district much interest attaches to
the results of deep development at the
Interstate Callahan. and it is crafty
ing to state upon official information
that the results have been most salts
factory. What the showing will be
ON the No. 10 level remains to be de-
termined as the crosscut from the bot
tom of the shaft has not yet reached
the vein. 1t may be stated, however
that on the No. level, which is 1850
feet below the main tunnel, there is
splendid showing of ore, cores
ponding in size of ore body and quail
ity of ore with that found in the up
per levels The percentage of iron
has not increased with depth, while
the proportion of lead as compared
with zinc continues to increase as
depth is gained The characteristics
of the vein, the formation, and in
fact all the conditions surrounding
The great ore deposits above, are the
same on the No. level, and so far as
can be determined at this time these
conditions will be found unchanged
on No. 10 when the vein is reached
Bearing in mind that the bottom of
the shaft is not below the water level
of Beaver creek, and comparing the
with the deep development
Of other mines of the district, it is
reasonable to assume that, the Inter
state Callahan ore bodies will con-
iinue far below the No. 10 level
Nipsic crosscut
Owing to the shortage of men, work
was recently suspended on the Nipsic
,rosscut, but it is expected that work
Will be resumed within the next few
lays. 1t will be recalled that few
months ago the Interstate Callahan
announced that a large
BODY of lead silver ore had been cut
~ diamond drill in the Nipsic, but
hat the extent and value of the
trike could not be definitely deter
mined until the vein could be reached
" crosscut the distance to be run
icing about 400 feet Only about rs
eet remains to be run, and it is ex-
,ected that men will be on the job
within a week

nents Of zinc concentrates averaged
8 per cent zinc and less than per

veraged SO per cent lead and 20
unces of silver. Shipments are still
Glow normal on account of the
heritage Of machine men and labor
neficiently generally Since the first
f the month, however, the labor sit
alton has decidedly improved and
t is believed that with the approach
f cold weather less difficulty will be
ncountered in getting men for I'M
erground work. The fact that all
Their large mines of the district also
epOrt improvement in the labor sit
alton indicates that the tide has
lrned and that the mines will soon
e relieved of the heavy handicap I'M
err which they have been working on
ccount of labor shortage.
