Description Of the
Shannon Mines.

vi the great mining properties that
are today making Arizona famous as
copper producing territory and, more
than this, are bringing Graham County
into prominence for its mineral wealth
is the Shannon Copper Company, of
Clifton.
While yet young in years OF incorpo-
ration, it has sprung into the notice of
investors as first rate proposition and
exploitation has only demonstrated the
accuracy OF such judgment.
Excellent lines of development have
been followed and already there are not
less than 10000 tons of ore, average FIVE
per cent in copper, lying on the dump,
awaiting treatment. This lot, however
will give a very inadequate idea of the
workings up to the present. Besides
this lot CT FIVE per cent ore, that has
been mined and shipped. is still larger
amount OF high grade ore. This latter
description has averaged over II per
cent in copper, and no less than 50, 600
tonS nave Deen marketed.
In connection with these figures, it
mnst be remembered that the company
is but three years old. 1t was formed
in 1899 to acquire and exploit certain
properties owned at that time by Hon.
Charles NJ. Shannon, and others. The
location is at Metcalf, just seven miles
north of Clifton. 1t adjoins the prop
erty of the Arizona Copper Company,
and that newly acquired by the Gen.
eral Electric Company. Even II the
already rich deposits OF the Shannon
Copper Company had not been struck,
the contiguity with such great produc-
ers as those just mentioned would be a
feature of no mean promise.
Conservative estimates place the pro-
bable net earnings at not less than
800, 600 per annum. These estimates
are based upon the present showings
and on the reports of some OF the best
mining engineers in the country.
Two exhaustive examinations have
been made by Mr.. John A. Church, a
New York engineer OF national reputa.
ton. He holds degree from the cele.
brated Colum bia College School of Mines,
having graduated in the class Of 1867.
Since that time he has constantly been
examining properties, and has the high
est testimonials and endorsements from
those whose opinions are unassailable.
His first examination, made in Sept,
1900, called out very favorable report.
That Of second survey Just completed,
goes into details much more fully. In
it, he says:
"a second visit to the Shannon has
confirmed and increased my good opinion
OF the property. The mine looks ex-
tremely we'll everywhere. The proposed
plan for opening for future work is good
and will be very economical.
1.-THE smelter site is we'll chosen, and
will give room and grade necessary for
very large works.
The large west ore body OF iron stained
ore yields 4.5 per cent; its tonnage is
large. The body OF ore in the east cross
cuts, and new grounds have been opened
in the Smoky.
''The east ore body is a very import
ant one. 1t is quartz porphiry, and
metallurgically valuable for it's freedom
from aluminium. 1t has known width
OF 40 feet going north and In that direc-
ton ii has an average value 10 per cent
copper. A crosscut east from the end
of the drift extends so feet in very good
ore, yielding 9.73 copper. The grade
improves going to the east and the last
35 feet reaches an average of 1898 per
cent. In the main cross-cut, the ore
averaged 4.52 for length of II feet, but
the width is unknown. The average of
eleven assays taken in the total length
of 140 feet, is 7.9 per cent.
"Already it has been developed for q
length of 440 feet aud width of 40 feet
for half that length. 1t is fine ore. free
from iron sulphide, carrying it's copper
as a pure sulphide. 1t is the richest
large body Of sulphide ore yet found.
"From the mouth of the Boulder tun-
mel the distance to the present face OF
the east ore is l ,067 feet, and OF this 400
feet is ore. AS to value, 80 assays taken
in ore Of more than two per cent grade,
gave an average value of 5.85 per cent.
Later developments raise the average of
the Boulder Shannon level to per
cent"
The main Office OF the company is in
Boston, Massachusetts,, a city that pro-
bably stands second only to Glasgow,
Scotland, for money invested in copper
mines. The Boston Stock Exchange
has board especially for quotations of
copper stocks, and special call. They
are very particular and exclusive as to
permission for listing any company on
change, and only those who have prov
ed, or can evidently prove their worth
are allowed listed. In short time
however, Shannon will be quoted on
change with it's authorized capital OF
81, ,000,0 900 and par value OF $40 q
share.
1t is first class property and seems
destined to be great copper producer.
