Mines ARE ACTIVE
IN GLOBE DISTRICT
The Miami Copper Company
Breaks Its Record
For Production.

Globe, Ariz, Aug. 1.-THE produc-
ton of the Miami Copper for July was
a little over S,OOO,O 900 pounds of fine
copper. the highest monthly production
in the history of the mine. During the
month 96,4O3 tons of ore, dry weight,
was mined. and 1912 feet of drifts and
raises were driven. a third eightfoot
Hardinge pebble mill has been added
to the equipment of the fourth unit,
of the concentration, affording a slight
increase of capacity. 1t IS believed
that the monthly production viii mere
after be maintained close to the 3,OOO,-
600 mark. A large proportion of the
ore mined comes from square set min
ing next to the Gaping and from de-
EeIopment work, the rest from the
Snrlnkage Slopes and from the dump
at No. shaft. The new machine shop
1t No. 1, or main shaft, is finished and
IS being equipped, and buIldlnS TO
contain the mine office and the enSl-
necring office is nearing completion
Also a contract has been let for the
steel work for a large new change
house, 81 by 80 feet, two stories high,
and designed to accommodate $50 men.
Exploration by diamond drilling con-
tinues on the $40 foot level but con-
siderable difficulty is experienced in
obtaining a core. The northeastern
territory is being explored with two
churn drills. About 1000 men are en-
ployed, of whom $50 are underground.
Development at Inspiration.
The contract for the railroad con-
struction at the Inspiration ConsOli-
dated mines has been let to Macarthur
Brothers and ground should be broken
within the next two or three weeks. h.
Kenyon Burch, chief mechanical enSi-
neer, has established his office at the
Inspiration camp with a force of
draughtsmen and assistant engineers.
The chief draughtsman is George H.
Booth who held similar position
with Mr.. Burch during the construc-
ton OF the Miami concentration. A
temporary engineering office building,
80 by 120 feet, is being erected near
the mill site It will be occupied by
Mr.. Burch and his assistants when
completed and Will be used until the
construction work is finished The
development of the Inspiration mine is
proceeding at the rate Of $500 feet per
month. The two main working shafts
are being sunk. the first haulage level
is being opened up at many points, the
ore being hOiSted through the Joe
Bush shaft, stations and ore pockets
are being cut at the first haudage level
in the scorpion and the Colorado
shafts, and an incline is being driven
from the main tunnel to the surface.
After that is finished, a hoist will be
erected and the incline Will be sunk
to the haulage levels and will be used
exclusively for men and timbers. At
the Live Oak mine, a pumping station
is being cut at the 11GO foot level in
No. shaft and steel head-frame IS
which the sinking of that shaft will be
resumed The Sulphide tunnel is be-
ing widened to seven and half feet
and viii be equipped with double track
for electric haulage.
Churn drill hole No. . of the South
Live Oak Development company has
been discontinued at a depth of 755
feet in the granite porphyry without
discovering chalcocite though silicateS
and carbOnates of-copper were noted at
various times. The drill is being
area at the northern end of the prop
erty adjoining the Needles group and
it is expected that hole No viii be
started inside of q week The schist
is mineralized and engineers who nave
examined the property believe 1t Of
fers a better chance OF finding ore
than the granite pOrphyry area
Old Dominion Production
Old Dominion produced 1106 short
tons of Blister copper in July. EnSi-
neers under H. Kenyon Burch are
working on the plans for the concen-
traitor. Proposals for steel work ana
machinery are in but no contracts
have yet been made Construction
will probably be started inside of two
the last section of the Kingdom shaft
has just been started ana the job
should be finished in about two weeks
The section is 135 feet deep and the
last three weeks have been spent in
stripping that part of the shaft, that
is, charging it from one to two com
partments- The work is being done
by Nicholson and Weideman, con-
structiOn engineers and contractors
The Copper Hill shaft a the Arizona
Commercial is being enlarged to three
above the fourth level
and there Will be probably little other
work done underground until the new
equipment shall have been erected,
which Will probably be within two or
three months. The compressor at the
Eureka shaft has been moved to the 4
Old DOminiOn-pOwer house and a five
inch pipe line has been laid from the
power house to the Copper Hill shaft
About 25 men are employed.
