The Wallace miner. [volume] (Wallace, Idaho) 1907-current, 1918-02-07

No. was extending the east drift on
No. 2 level 379 feet disclosing good
ore 2 to s feet wide. This is regard
ed important, as depth is gained driv-
| ing east and substantial ore shoot
| is expected. On the No. 6 level ore
| has been developed 800 feet drifting
east south of the porphyry, averaging
from to feet wide. No stopping has
been done on this ore. West on this
level drift was run SO feet, show
ing little ore, but in stopping ore came
in about 20 feet above the sill floor
and shows feet of high grade zinc.
No. 7.
This is new level and an ore shoot
has been developed 500 feet long. The
ore is high grade and from to 10
feet wide east and south Of the por-
phyry and undisturbed by faulting.
Farther west the vein has been dis
placed by two faults "a short distance
to the south. The ore here is high
grade and the shoot from 5 to II feet
wide. The ore extends further east
or thistlevel than on No. 6.
No. s level has recently been open
ed and the ore was encountered 100
feet further west than on No. 7. Drift
ing on the ore has been extended 120
feet and shows from 6 to Z feet of
high grade zinc.
Rake of Ore Body.
Commenting on these ore disclosures
Mr.. Newton says: "The theory has al
ways prevailed that our ore body in
the Interstate vein would gradually
work to the west, but our develop
ment work in depth is proving that
this theory. is not correct, as our ore
body to the east and south of por-
phyry is showing the greater improve
ment comparatively; and in greater
depth I look for our entire ore body to
be east and south Of the porphyry.
The drift west on this level has been
extended only short distance"
Callahan Vein.
The only development on the CAL
lahan vein during the period, Mr.
Newton says, was on the No. S level,
and drift has been run on it 70
feet, showing from to feet Of good
ore which is now being stopped.
On the No. level of the Nipsic an
ore shoot 100 feet long has been de-
veloped, being from Is to 80 inches Of
solid high grade zinc. A crosscut is
now being run from No 6 level of the
Interstate Callahan through the Sill
yer State to the Nipsic
Tonnage in Sight.
Under this heading Mr.. Newton
says: "Our ore reserves so far devel-
oped above No. level, as Of Deem
Der 81, 1917. are approximately 310,-
900 tons, or at the rate of present
production, about two years ore sup
ply.
"In addition to the 100000 tons of
ore now blocked out in the mine above
No. level, we have approximately
225,OO0 tons Of mill tailings stockpil-
ed at the MILL which will be retreated
in our new flotation plant and made
ready for shipment The average as
say of this stockpile is 10 per cent
zinc. On the above figures we estim-
ate, therefore that we have better
than three years ore supply now in
sight in the property and in this stock
pile, to say nothing about the rich ore
that is being developed on the No. s
level. These figures are based on our
present rate Of production, i.e, ap-
proximately $4,000 tons per month of
mine run, or 5000 tons per month of
shipping product.
1.-THE mine operated $40 days. and
the mill operated 4S2 days during the
period covered by this report.
During the eighteen months per-
iod the mine has maintained a high
grade mill feed, showing zinc con-
tent Of 23.4 per cent zinc after the
crude ore was sorted out, and with the
character of ore that Is being devel-
oped on No. level, l see no reason
why we can not continue to deliver a
high mill feed"
