BIC DEVELOPMENT
BY MIAMI COPPER
Crushing Plant Remodeled
Rope Span to Stock Pile
Cananea to Resume.

Globe Ariz.. April 12.-Arrangemen.s
have just been made for the construe-
tion Of wire rope span over Che

south Of shaft No. of the Miami Cor

ore bins. The necessary oUeratfu.-
power is to be furnished by the small
moist which was used in sinking shaft
No 4 orders Tor material have been
placed and actual construction vo~lz
viii probably begin within the next
30 days.
Work on the remaining 5000 tons
Of ore In the stock pile at No. shaft
which has been suspended for a short
period. is TO be resumed Immediately.
At the mill, the retreatment middIuE
plant and the four Deister MulupIeE
fitting tables recently installed in the
sixth unit are running smoothly and
proving highly efficient This unit is
saving One-half 10 two pounds more
copper per ton Of ore treated than
of the other sections OF the mill, due
partially to the retreatment OF the
mlddlings and partially to the better
effect secured by the using of the
fitting tables
The crushing plant is being remOd-
eled so as 10 insure a II inch size
product. Specifications call for the
additional equipment Of two sets OF
rolls, two screens. and two elevators
The remOdellnS OF this branch IS
largely due to the greatly increased
hardness Of the ore as disclosed by
milling operations over the theoretical
hardness used as data in the design
ing OF the plant. All OF the original
rolls have been entirely replaced by
the massive, 42-inch diameter by 10
inch face, spring, Traylor special
rolls. With the exception Of unit No

rla
The Chilean mills IN No are IN Sucn
excellent shape that il viii not be
necessary TO replace them for some
time. During autumn il is highly
probable that the lower portion OF the
mill viii be remOdeled and posi- bly,
that two more units viii be added
Work ut Cananea to Resume.
J. Parke Claiming stated that the !
closing Of the Cananea smelter would
in no way effect the cOmpany's (
operations, as the railroad officials had (
si-nified their intention Of furnishing
all the cars necessary for loading pur- {
poses Also that operations at Can J
anea are TO be resumed shortly.
Development work on the Captain !

as possible On the $40 foot level Z
DEVELOPMENT work is still progressing (
steadily although not as enerSetlcally 1
as on the Captain side At present All I

Inspiration Consolidated.
The Inspiration Consolidated cOmpa-
ny's development for March amounted
10 $3.50 fest for the Inspiration division
Of which $500 feet was drifting, $50
feet raising and $50 feet miscellaneous
and for the Live Oak division 200 1eeL
drifting 6G5 feet and 80 feet raising,
giving a grand total Of 4270 feet for the
month, showing an increase for the
Live Oak division of 100 feet and de-
crease Of 1850 feet for the Inspiration
division The decreased footage IS due
TO the temporary laying off Of a por-
ton Of the miners at the Joe Bush
shaft pending the decision of the COM
pany in regard to the method of min
ing to be employed A total of 1920
tons was mined at the Inspiration di-
vision, the stock pile at the Joe Bush
shaft now totaling 10000 tons Of com
mercial ore
At present there are 1000 600 tons Of
ore laid out at the Joe Bush available
for inme date extraction If necessary
