THE FUTURE OF ZINC

4 UST BEFORE his departure for
New York to attend the annual
meeting of the directors of the
company c. W. Newton, mana
ger of the Callahan Zinc-Lead COM
pany announced that the main shaft
had been sunk to the No. IL level,
which, including the stump so feet
deep, is 1900 feet below the main
working adit of the mine. station
is now being cut for the new level,
upon the completion of which a
crosscut will be run to the vein, which
it is estimated should be reached in
about $50 feet Mr. Newton stated
that the vein on this new level will
be thoroughly explored and it is ex-
pected that the results will prove
equally as gratifying as on the levels
above. While this underground work
is going on, a few men are being en-
ployed in the mill making repairs
and minor changes in order to have
everything in readiness for a resump-
ton of production just as soon as the
condition of the metal market will
justify it. When this will be is of
course question that no man can
answer and it must be admitted that
there is nothing in the present situa-
ton to indicate that it will be in the
immediate future. But the confidence
displayed by the company in pushing
development is highly reassuring of
future operations.
Addino TO Ore Reserves-
In his report for the year ending
December 81, 1920. Manager Newton
had this to say regarding ore reserves
lat the close Of the year: "A conserva-
tive estimate of our actual ore re-
serves. of a grade that will furnish
the mill an average feed of 1914 per
cent zinc or better, with the usual 6h
per cent lead content and ~ ounces
of silver is about 10000 tons, which
does not include ore contained in our
outside or controlled properties, more
fully described hereafter There is
also a certain tonnage of low grade
ore which is not included in the
above estimate, as well as probable
ore that we expect to prove as our
development work progresses. We
are now pushing development work
as rapidly as possible for the purpose
of adding substantially to our proven
reserves"
Since the date of this report the
shaft has been extended to No 10
level, the development of which is
understood to have made a large adj

ploration of No. II level, which is
now under way. will add 200 feet
more in depth of virgin ground which
may reasonably be expected to find
the ore shoot as large and rich as in
the ground above. In this connection
it is worthy of note that there has
been a pronounced increase in the
of lead in the deep work.

Outlook for Zinc.
The Callahan mine ranks among
the greatest zinc producers in the
west and it's profitable operation de-
ponds upon the restoration OF the zinc
market That the market will come
back is just as certain as that the
business of the country will eventu-
ally be restored to a normal basis.
In fact, it is the opinion of the best
on zinc that under normal
conditions there viii be a greater de-
mand for the metal than ever before,
due to the fact that it has been found
for many new uses and
that the field of its usefulness is
steadily expanding. This encourag-
ing outlook for the metal is empha-
sized locally by the action of the
Bunker Hill e Sullivan company in
the construction of an electrolytic
zinc reduction plant an enterprise
that will require a large expenditure
and certainly would not be undertake
en- by that ar-seeing company I'M
less there was an assured future for
the metal
