STORY Of DUTIES
COPPER DEPOSITS
Four Deposits Surrounded by
Interesting History Are
Worldwide Famous.
SILVER ORES GIVE WAY
WITH DEPTH TO COPPER
Some Deep Work Necessary to
Bring Mines to Present
Shape.

There arc four deposits in the Butte
copper camp which stand out conspicu-
ously In the underground history OF this
district says the Boston News Bureau.
The first is the Anaconda, which In
the early days OF the Marcus Daily re-
eimc was the greatest copper and silver
producer in the world. Above its 1000
foot level. Anaconda ores were fabulously
rich At greater depth, however, the
ores deprecated both in silver and cop
per contents until between the 1900 and
lSoO-foot levels Anaconda cncoun tered
an impoverished zone, only to strike at
ondary enrichment when copper values
again began 10 improve. on the 900
foot level there is continuance of the
Improvement noted on the 1000 and 2200-
foot levels.
Next in Importance may he mentioned
the rich Comanchc mine Of the Boston
Montana. which was purchased
through Captain Palmer, then OF the
Butte s. Boston, and which made the
ground for the later STANDARD or at
tack on a. S. BIeelow.
In many respects the most scnsa tional
discovery OF ore In Butte has been on
the 1900 and 1900 foot levels OF the North
Butte. The Edith May vein on the 1900
foot level has been the wonder Of the
Butte camp. This body OF orc has made
1T possible to achieve for this property
what no other mine In Butte has ever
sccomplished-the hoisting through one
shaft OF 1900 tons OF orc per day. which
yielded al the Washoc smeltcr out
put OF between 3.50o,000 pounds and A.
100000 pounds Of copper per month.
Never before In the history of Butte or
any other camp has one shaft produced
$4,000 ooo TO 10000, 900 pounds OF copper
per annum.
In seeking the continuation Of this big
body OF ore. North Butte put down ITS
shaft to the 1000 and 22OO-ioot levels.
crosscut back to the veins. only TO find
that the Edith May vein had split on
the copper contents OF the "brs nches'

the 1900 foot level above. On the goo

course, In ore or vein matter carrying
copper, but the rich ore chute enconn-
wealth Of the North Butte. has not vet
been met with. il may be found later.
For a clear understanding of this matter,
IL should be borne in mind that the North
Butte copper deposits are Of two char
acters; there is the vein carrying cop
per, usually richest I'm the center and
with the copper contents sometimes per-
meating the walls Of the vein. so that
ii is often difficult to define the profitable
area OF mining. This is largely deter
mined by the price Of copper and careful
of the vein are approached or passed
through. But In this vein matter. rich
punches OF ore OF varying size are en-
countered and when they are extensive
they take in general a lenticlIlar kid
ney form Of varying shapes and are
called in the mining world 'ore chutes.
II is this ore chute of the Edith May
vein which Is today missing in the bot
tom OF the North Butte
1t is quite apparent that so far as
plorations have proceeded at this point
North Butte is running into lower grade
ore, but IT is not impossible that With
the driving OF these drifts further west
and IT may be said that the sensational
ore body on the lS0O-foot level was very
wide and 500 feet in lengih-better values
will be met
Next IN Importance among the big
copper deposits should be, ranked the
Karus mine now belonging 10 the Butte
Coalition Co, and for many years serv-
ing 10 provide i. Augustus Helnze with
the sncws of war in his defense against
the Amalgamated Copper Co.
