OF 100000 tons per acre. This was
prospected by churn drills and after
ward by regular underground methods,
there being over 81 miles Of under
ground work. Wonderful to relate,
this vast amount of underground work
was begun oily two years ago. Eigh-

to be hoisted more than from $50 to 800

which bids fair to rank along with the

Big improvements In Miami.
Four mines at Miami. Arizona, have
been opened on the great deposit Of
disseminated copper ore of that dis
trict. From east to west these are the
Miami, the Inspiration, the Keystone
and the Live Oak. They are opened on
what is really the same ore body. The
ore is a schist, mineralized chiefly with
chalcocite. UD to the present, a total
or about Sc, 0OO, 900 tons of ore is
claimed to have been developed in the
four mines mentioned
The Miami Mine.
The Miami mine is the big producer
of the Miami camp and the pioneer Of
porphyhy copper mines and big con-
centrating plants in the southwest It
has a big concentrating mill, with six
sections or units. The foundations are
ready for two more sections leach of
$50 tons daily capacity There is eS-
timated to be in this mine IS, 900, %
tons of ore blocked out averaging 2.5S
percent copper. Exploration with dia-
mond drilling continues on the $40
level The company is mining and con-
centrating an average of 5000 tons Of
ore a day, the total for July being &c.
COS tons, and Tor July the productlon
of fine copper is 100000 pounds. The
same month 1912 feet OF drifts and
raises were driven All mining is be
ing done above the 420 foot level, but
the $50 level is being opened UP. Pits
are being dug for foundations for
failing tower. It will be equipped with
four bucket elevators, having a inch

which it is now being run may De

The keystone mine, near by. is eSti-
mated to have a total reserve of B.

The Live Oak is estimated to have de-
veloped 100000 tons of ore blocked
out, avering 81 percent copper
The concentrates from the Miami
mill are sh- Oped to the distant smelter

Inspiration Consolidated.
The development and construction
program of the Inspiration. Consolidat-
ed Copper company, entalling the en-
ployment OF over 1000 men and the eX-
penditure of nearly 100000, near
Miami. Arizona, during. the. next Two
years, has been started. The site fl
nally selected for the concentrator IS
about one mile east of the Inspiration
mine and a mile north of the town OF
Miami Managing director w. b Al
drich has recently finished a visit to
the property and settled the main
points of the program. He says:
The site for the 1900 ton plant has
been decided upon and all the neces-
sary land secured. 1t viii consist OF
six sections of 1850 tons each The
flow sheet, or method of concentra-
has been conducting tests on the ore
for the last five months, viii be adopt
ed. It is the logical extended applica-
ton OF the principles of the 'roughing
system developed by the Utah Copper
company"
plans All Agreed Upon.
The general arrangements of the
working shafts, crushing plant and
concentrator have been agreed upon.
and the details Of mill design, shaft
equipment and the specification for
engineers, Redpath and McGreSor.
About 100 men are being employed IN
derground and the number will be rap
idly increased as soon as additional
compressor facilities can be provided
The steam power plant will have
capacity for generating a minimum OF
1900 horsepower, and the power will
be distributed in the mill, IAine and
shops by high tension electric current
There will be over 100000 eNpend-
ed in the development and equipment
of the mine and the construction and
equipment of the concentration, power
house, etc, and over 1000 men will be
employed within the next few months
Big Force Employed.
Over 400 men are now employed and
the force is being increased. The pre-
llminary survey for the railroad from
the mine to the concentration has been
completed and the contract for its con-
struction has been let to Macarthur
Brothers and ground will be broken
within the next two weeks.
The development work IN the In
spiration mine is proceeding at the
rate of $500 feet per month, and de-
Velopments have disclosed the exist
ence of an ore body 30 feet thick and
$500 feet long. 1t is estimated that
this ore body contains 10000, 600 tons
of ore averaging 1.9 percent copper.
Additional Douglas Smelteries.
The Calumet & Arizona Mining COM
pany is erecting one of the largest and
most uptodate copper Smelteries IN the
United States at Douglas, Ariz Mean
while the old plant is being steadily
operated.
Work is in progress on the new
smelter. Much of the concrete work
has been completed and number of
important contracts have been placed
for the equipment of the new smeltery.
Redpath & McGregor, engineers, de-
signed the plant and are supervising
the construction.
Under the management Of Capt.
Greenway, an exofficer of the Spanish
war under Col. Roosevelt, the instala-
ton of this new smelter was inaug-
urated this year.
Description of New SmeItery.
The new smeltery will include so
many novel features and new ideas
that have been worked out by metallur-
giSts and smelter experts that it is
predicted that it will be the finest
smelter in the United States.
The present ore receiving bins will
be equipped with chutes suitable for
feeding the ore into hoppers of convey
or feeders and 80 inch conveyors to
