KENNECOTT COPPER MINING
It is well known that the Kennecott
Copper corporation is operating suc
cessfully and is, in fact, obtaining
brilliant results today in Alaska. This
property has the advantage of
handling large bodies of the highest
known grades of copper ore, begin
ning at the outcrop. The actual ton
nage handled has not been large, and
the cost, even under war conditions,
is not over 8 cents per pound.
The entire region in the nieghbor
hood of this property has been thor
oughly mapped and reported on by
the U. S. Geological Survey. All of
this information is easily acessible.
Anyone studying this mass of infor
mation will agree, after careful reflec
tion, that this region offers attrac
tions to any development company
that has no unreasonable hope of find
ing a bonanza without expending a
proper amount of time, skill, and
money, all of which are as much, but
no more, required in this Alaskan dis
trict as in any other part of the world.
Of course, all prospecting work will
be necessarily done under extrava
gantly expensive conditions and with
out the usual facilities for obtaining
supplies and labor. Costs will vary
greatly, but after the work is central
ized and systematized, they will be
made reasonable. The large gold
mines in the nleghborhood of Juneau
have not shown unreasonably high
costs, but they have had their difficul
ties in obtaining sufficient labor and
in recovering the gold in their low
grade ores.
If anyone asks the point-blank
question, “What Is Alaska like?" It
is as difficult to give an enlightening
reply as It is to describe Africa or
liussia in a few words. There are as
many different local conditions of
climate and topography as there are
in any other large country. It is hard
to convince some people that it is at
all practicable to work throughoui the
year. On the other hand, one very
capable Arizonan operator believes
that mining costs over an extended
period should not be higher on the
average in Alaska than in many other
localities where copper mining Is be
ing conducted profitably.
In the already prospected regions
of Alaska there are no easily recog
nized surface indications of large
bodies of primary orejsuch as, for
Instance, the monht&IirVt oxidized
material at Ajo, Arizona, Where very
little overburden, large acreages of
oxidized material lay absolutely ex
posed to all prospectors. As one clev
er traveler In Alaska said, many of
the mountain regions in Alaska l'tter
aly “rain rocks.” This part of the
world, of course, is subject to grdSit
fluctuation of freezing and melting,
so that the forces of erosion are nat
uraly very active. This has its effect
on the ore and is the cause of the
great concentration in fissures and
along contacts.
The following description of the
Bonanza mine Is borrowed from Mr.
Moffit:
The Bonanza mine is In the moun
tains between the Kennecott glacier
and McCarthy creek, at an elevation
of 6,000 feet. The first large ore
bodies found were in the magnesian
limestone, so that at one time it was
supposed this rock had controlled the
ore deposition and work was conduct
ed accordingly. This supposition had
to be given up, however, as the work
proceeded, for ore was found in both
the magnesian and the non-magnes
ian limestone. In the early days a
great deal of talk was heard of the
“favorable” lime, by which was
meant the magnesian lime. Also, a
great deal of talk is heard locally
about bedding-planes. The bedding
planes, or flat faults, indicate the
movement of one limestone bedon an
other, or movement along a plane par
allel or approximately parallel to the
planes or bedding. Bedding-plane
faults occur in the lower part of the
Chitistone limestone at many places
and at least four are recognized in
the Bonanza mine. The ore is dom
inantly chalcocite. The great ore
bodies belong primarily to the ver
tical fault system and have been
found at the intersection of the ver
tical with the flat faults. They lie
above the flat fault and terminate
sharply against the underlying lime
stone. The exposures at the surface
of the Bonanza mine show no more
oxidized ore than those in some of
the lower levels. Oxidized ore con
tinues to the 700-ft. level. All small
veins in stringers must be closely fol
lowed for many of them develop into
valuable bodies of ore within short
distances.
The copper deposits of the Jumbo
mine resemble in most respects those
of the Bonanza. The mine is in the
Chitistone limestone, just above the
contact with the underlying green
stone. The width of the ore-bearing
ground worked is not less than z
ft., yet the limits of the ore have not
yet been reached. In form the ore
bodies are like those of the Bonanza,
large tabular masses of chalcocite re
placing limetsone along the north
easterly faults. Ore was deposited in
great quantities at the insectlon of
the vertical and bedding-plane faults,
between the 400 and 600-ft. levels.
The great orebody lay for the most
part above the bedding-plane fault
between it and the magnesian lime
stone. It extended from a point a
short distance above the 600-ft. level
to a point 30 ft above the 400-ft level.
In projection on a horizontal plane it
had a length of 400 ft. A horizontal
section of the orebody at the 500-ft.
level is shown. This great mass of
ore was practically solid chalcocite,
with which was mixed an almost In
significant quantity of included
limestone. It has yielded 50,000 tons
of copper ore, much of which ran 76
per cent. This is the largest single
body of this grade of copper ore ever
mined.
The Eiie mine is a little more than
3% miles north of Kennecott and less
than Vt mile from the galcier. The
ore so far uncovered is much more
oxidized than that of the Bonanza and
Jumbo mines. At least one well-de
fined bedding-fault was encountered.
This mine is equipped with an aerial
tram 2700 ft. long, running between
the lateral moraine of the Kennecott
glacier and the upper adit. Most of
the ore shipped from Kennecott is of
high grade and requires no concen
tration. Part of it, however, is con
centrated in the mill, the tailing from
which is treated in the leaching-plant
with ammonia, which dissolves the
copper carbonate. By this process 65
to 72 per cent of the copper content
is recovered from the tailing. The loss
is probably due to the fact that fine
particles of chalcocite are not attack
ed by the ammonia. Much experi
mental work is being done to perfect
the leaching-plant. The difficulties
encountered have been mechanical
rather than chemical.
The Mother Lode mine is situated
northeast of the Bonanza mine. Since
1913 it has made shipments of ore
each winter. This property has Just
been purchased by the Kennecott
Copper corporation. The ore is chiefly
chalcolte; besides copper, it carries
silver in the ratip of one ounce to
each 4 per cent of copper.
The deposits so far exposed are
high above the limestone-greenstone
contact, and in this respect differ
from the orebodies of the Bonanza
ond Jumbo mines, which are near the
contact The mlno is equipped with
a tramway having a length of slight
ly more than 6000 feet.
Another photograph shows a pros
pecting tunnel on the Oren group of
claims driven on a fissure, in whloh
''stringers and veins of high-grade ore
have been found. This working is con
nected by an aerial tram with the bed
of McCarthy creek, 2700 ft away,
k
and the operations are prompted by
the supposition that a similar geo
logical formation should contain sim
ilar ore to that of the Kennecott
group.
The showing of copper, In the form
of patches and lenses of bornite In
the limestone above and near Its
contact with the greenstone, is of a
most Inviting character, because
among reasons the ore Is so high
grade as to remind one of precious
metal mining that the conventional
dlseminated copper deposit.
The purpose of this sketchy de
scription of the district by one that
knows It well Is to suggest that it of
fers reasonable chances to the ad
venturous prospector, particularly to
the young man returning from the
war and previously possesed of some
knowledge of mining.
NOTE. In 1917 the Kennecott
mine produced 265,579 tons of ore as
saying 13.78 per cent copper. Of this
206,263 tons, averaging 8.92 per cent,
v/as treated in the mill for a yield of
29,559 tons of concentrate averaging
53.52 per cent copper. The recovery
was 85.98 per cent. At the leaching
plr,nt a total of 98,075 tons of tailing
avergalng 0.9 per cent copper, was
treated, for a yield of 1,244,200 pounds
of copper. The aggregate shipments
to the smelter came to 89,799 tons
averaging 88.57 per cent per ton. The
ore contains silver and gold. During
1917 a total of 933,573 ounces of silver
was recovered, with 78,211,429 pounds
of copper. It is rumored that ore rich
in gold has been struck recently in
the lower workings. The Kennecott
corporation has absorbed the Braden
copper mines and other mining prop
erty, so that the exact performance of
ho Kennecott mine la now obscured.
Production averages 6,000,000 pounds
of copper per month.—Mining and
