|NTERSTATE-CALLAHAN NINE RANKS THIRD
As ZINC PRODUCER IN UNITED STATES
WONDERFUL SHOOT, 800 FEET LONG, SHOWS MUCH SHIP
PING oRE-MlLL MAKES PERFECT SEPARATION
OF LEAD ZINC

There are just two mines in the
United States that produce more zinc
than the Interstate Callahan ana
those two are the Franklin Furnace OF
New Jersey, which ranks first, and the
Butte & Superior of Montana, which
ranks second, the Callahan
ranking third. This rating of the big
Occur dlAlene zinc mine will not be
found in any published annual statis-
tics Of the zinc mining industry, be-
cause as a big producer of zinc the In
terstate- Callahan is less than a year
old, but it is a fact nevertheless that
it is the third largest producer OF zinc.
The most remarkable fact in connec-
tion with this statement, and one that
gives a strong intimation of what may
be expected in the future, Is that 80
per cent of the great output OF the In
terstate- Callahan is produced strictly
in the course of development. 1t Is
therefore not improbable that when
actual mining of the ore begins, the
mine may pass above the third place
among the zinc producers.
A Wonderful Ore Shoot.
There are two parallel veins in the
Interstate Callahan, approximately zoo
feet apart The one in what was or
iginally the Callahan ground is lead
silver and it's exploration has shown
It to be a great mine in ITSELF The
other vein is almost wholly zinc with
some lead and is found both IN the
original Interstate ground and IN the
Callahan. It's development has been
one of the big mining sensations OF the
district, and it's further development
promises new sensations. The shoot is
now 800 feet long and the face OF the
drift shows no evidence of decreasing
in size and quality. How wide 1t is in
the face is not known, but at various
places it has been crosscut showing
II to be from 20 to 40 feet wide and
without foot of material that could
be called waste or that would not pay
to run through the mill.
Twelve Feet Of Shipping Ore.
It is stated on unquestioned author
ity that much of this ore shoot SHOWS
eight and 10 feet of clean shipping ore,
and in one place there was II feet, ac-
tual measurement This means ore
that will run from 50 to 90 per cent
zinc.
The face Of the drift on this ore
shoot now shows an increase IN lean.
# comes in streaks along side OF the
zinc. but not in combination with 1t.
This lead is exceptionally high grade
and also carries an exceptionally high
value in silver An idea OF the char-
acter of the ore that is coming from
the mine is contained in the statement
that a few days ago IS tons of ship
ming ore was taken in one day from
the sorting belt.
Mill Does Good Work.
The capacity of the Interstate CAL
lahan mill Is now taxed to handle tne
present output, from which 1t is evil
dent that when big mining operations
begin additional capacity will nave 10
he provided, for it should be borne IN
mind that while the mine is sending
out a large tonnage, the work Is large
" in the nature of development.
The mill makes an almost per1ec'
separation Of lead and zinc This IS
evidenced by the fact that the lead
shipments to the smelter have rarely
been penalized on account OF higa
percentage of zinc.
Another Distinction for Interstate
Callahan.
The ore from the Interstate Callahan
mine is the only zinc ore from west
ern mine that is used in the manu-
facture of paints. This is explained py
the statement that the high grade
character of the ore enables it to es-
cape the excessive cost Of refining to
which lower grade ores are subject.
The hauling of the ore from the In
terstate- Callahan mill gives that Sec
ton of Nine Mile very animated ap-
nearance. The contractor, John Nor
rison, has AZ head Of horses engaged
in the work, besides numerous other
teams engaged in hauling supplies OF
various kinds.
