Operating conditions were much
improved ana temperatures were re
duced by improved mine ventilation
OH this level.
A new Arctic refrigerating plant
was installed at the Junction to SUI
/ ply cold drinking water for the un-
/ derground and surface operations.
The operation of this plant has been
satisfactory and the improved drink
| ing water is much appreciated by
the men.
| A new Allis-Chalmers 5000 K. w
I1urbo generator was installed at the
smclter power house. This turbine
has been in satisfactory operation
since July. The installation Of this
turbine makes the electrical capacity
lat the smelter equal to the steam
| rlant capacity.
The Sullivan Corliss engine air
compressor, formerly at the Oliver
shaft, was rebuilt and installed IN
the smelter power house. 1t has
leen in operation since November
replacing the old straight line COM
Iressors and effecting material re-
duction in steam consumption.

raid $26,767.21 in sick, accident and
Death benefits. The regular dues
were sufficient to meet the payments
and leave small balance at the end
of the year.
Early in the year Dr. F. I. Wright,
for many years chief surgeon at the
alnelter, announced his wish to &c
tire from active service. Dr. Wright $
interest in the hospital was our,
chased by the company. The build
ing was completely remodeled, and
a contract covering surgical, medical
and hospital attention was made with
DR.. e. w. Adamson, of Douglas, who
is now in charge cf the hospital
and medical work at the smelter.
The company accepted the state in

created industrial commission of Arl-
zona This commission adjusts all

/ wish TO express my appreciation
and thanks to every department head
and the men at the mines and smell

and cooperation exhibited through
cut the year.
Following is the report of the
Verde Central mines c. & A. sub
s:diary, for the year of 1926:
Mr. Gordon f. Campbell, president,
Verde Central Mines, Inc,
/, Calumet Michigan.
Dear Sir:
i A total of 9414.5 feet of develop
ment work, not including station
cxeavatfon was done in the year
1896. It8eo1isisted of 86115 feet of
cross4cutting and drifting; 348 feet
Of raising and 455 feet of shaft sink
ing Water encountered in the mine
workings slowed UP our development:
4 =, bn 1nt half Of
the year. Much of the work was
preparatory to our program for 1927.
Much of the work was to develop
the Rock Butte ore zone en- the 6Oo'
500, 100, 1900 and 1900 levels. 1t
has demonstrated that the top of the
ore zone IS irregular dipping from
tncar the surface st the south end of
1.-THE Rock Butte claim to near the
4 500 level ut the north end that the
zone persists continuously for the
total length of the claim from this
cap to below the 1850 level; that 1t
is a large sllliceous low grade mass
carrying mineable lenses of high
grade ore; that it varies in width
| from 10 feet to over 100 feet, being
more siiiceous at the top and with
Increasing sulphides coming in at
depth.
our vertical shaft (No. p was
sunk from the 145O to the 1900 level.
stations were cut on the 1900, 1850
and 1900 levels. The rock encount-
cred in the shaft below the 1900
4 anG on these lower levels has all
carried disseminated chalcopyrite and
looks very favorable.
A very promising area along the
quartz porphyry greensboro contact
lis being developed on the 1000 level
in the Crown Point claim. the mfn-
eralization N til inu es persistently
along this contact but fault zone
has cut the vein into series OF
locks, with displacenents of so feet,
or more, horizontally. One block has
been developed go feet long with a
width of feet on the level and has
