Owns 24oo Acres
The Copper Creek company owns .py
location and purchase, 120 claims, en-
bracing 24O0 acres of minerahzed lanus
and mill sites, extending for Two anu
one-half miles into Graham ana wv
and one-quarter miles into Plnal couIs
ties, Arizona, containing deposlts o-
conner which are seemingly mex
austible. In the center of this empire
IS located the heart of the concern
comprising a powerful electric plant
100-fon concentrator, machine shops'
lighting plant, ice plant and com
pany store and houses, all con-
nected by wagon roads and aeriaI
tramways with the seVeraI sllal 70
and tunnels which lead the way TO
the mineral storehouses. The sec
tion is known to mining men as the
upper and lower copper basins ana IN
the wide porphyry belt in which the
ores occur the company mas deVeIoPe1
six distinct ore shoots, any one OIL
which is the making of copper NINE
OF the ore bodies developed two con-
sist of copper glance, with some car
donates; two are high grade oxides
with some sulphides and the other
two. showing no trace of oXidizatlon,
are true sulphides. Although the per-
manent water level has not been
reached, the ore bodies show little
signs of teaching, and in consequence
the values are high.
Railroad is Convenient
Since the extensive development
work of the Copper Creek company
and the Calumet and Arizona in that
section was begun, the Wlnkelman'
Phoenix and Eastern railroad, supslu-
tary line of the Southern Pacific, has
been extended to Winkelman, thirty
miles distant from the Copper Creek
properties, and the company has oullt
a magnificent wagon road through
a difficult canyon to the San PEDRO |
river road connecting with the ter1nl- |
nus, over which the machinery Tor !
the mill was hauled. The concentra-
tor building was designed for the ac-
com1nodation of a 250-ton plant and |
the first unit will be followed by 9TH
ers until the reduction works Will |
have attained that capacity. Within
eighteen months the officials plan to
have a smelter for the treatment OF
their crude ore of a high grade, and
the concentrates from the mill.
Pending the construction of the |
smelter all ores carrying 10 per cent
or over of copper will be shipped, ores
below that grade will be concentrated, |
the average being about five tons into
one although some grades of ore VIII |
be seven into one.
The company possessions contain all
the 1uxes needed for smelling pur-
poses. there being three big veins of
iron ore and bed of lime, and ten
year supply Of wood on 1000 horse
power basis, for the operation of the |
generating plant which furnishes the |
power.
The American Eagle Shaft
The principal shaft of the property
is the American Eagle, shown in one |
of the accompanying cuts, which is
equipped with an eighty-hOrse power, |
double drum electric hoist. The Sioux |
Chief and Grey Copper shafts are sim
ilarly equipped, but with lighter ma
chinery. The ores for the immediate |
operation of the reduction works will
come from the ore bodies developed |
through the American Eagle shaft,
which is $50 feet deep and connected |
on the 200 level with the plant by a
1350-foot tunnel. In the underground |
workings in this portion of the COM
pany's domain a large deposit of sui
phides and oxides has been blocked |
out ready for stopping, and will furnish
a mill feed running from 5 to per |
cent in the red metal, together with |
small values in silver.
A Remarkable Ore Shoot
One of the most remarkable shoots
of high grade ore in the state has been
developed through the Ute Chief shaft.
The rich carbonate ores of this local |
ity were mined through this shaft
years ago and transported on burro
back sixty-eight miles to Tucson for
shipment. A tunnel was driven in to
connect with the ore shoot at a depth
of 200 feet, from which point connec-
tion was made with the shaft. One
hundred and fifty feet from the portal
OF the tunnel W1nZe, hVe by seven
feet in dimensions, has been sunk for
100 feet into a solid mass of copper
glance At the bottom of the winze a
cross-cut proved the ore body to be
fourteen feet across and shipments
made in the course of development
work, as the ore broke, brought smell
ter returns of Ia per cent copper and
eighteen ounces silver per ton. Speci-
mems from this ore shoot assayed as
high as 81 per cent in the red metal
and forty ounces silver.
Workings and Equipment
The lower copper basin ore channel
is contained in a wide belt of por-
phyry, the walls consisting of diorite
on both sides, while in the upper basin
the walls are rhyolite. The Calumet
and Arizona is operating on the same
vein system in the lower basin. and
purchases power from the Copper
Creek company.
The Copper Creek has in all about
two miles OF underground workings.
The equipment includes a 3OO-horse
power Corliss engine and boilers and
250-horse power electric generator,
which furnishes light and power for
the mines, and a surplus Of power
