Construction work at the opera
at the Phelps Dodge operations, one
Burro Mountains is going on rapidly
and preparations are being made for
the erection Of the 1O0O-ton daily
capacity mill three miles north east
Of Tyrone. The experimental mill,
designed by DIR. Sanburg of Bisbee,
is running day and night and various
methods Of ore treatment are being
tried out; the successful method be-
ing the one that will be embodied in
the large treatment plant. Grading
is under way at the mill site and il
is believed that within two months
time the general construction Of the
mill will be under way. A TOWNSHIP
near the mill has been surveyed and
already some building erection is be-
ing done. There will be two towns
at the Phelphs- Dodge operations, one
of the present site, Tyrone for the
mine and power plant employees and
one near the concentration.
The experimental ore treatment
plant is now treating thirty tons of
ore per day. The equipment in the
plant comprises; one Blake jaw
crusher. Frazier rolls, Whitley tables.
Harding conical mill, and oil flota-
ton tanks. Up to the present time
no definite conclusions have been ar
rived at as TO the success Of the oil
floiation process but it is most likely
this method Of treatment will not be
used on the Burro Mountain ore.
The ore being treated in the expert
mental mill comes from the main
tunnel and other workings on Phelps
Dodge ground.
The concrete work of the power
plant, located near the No. . shaft
is completed and the steel construc-
ton work is now under way. The
plant will be equipped with two 1000
h. p. Diesel engines and power will
he generated for the operation of the
mines and also the mill.
The Niagara haulage tunnel is now
400 feet ip length and is connect
ed with the company's workings at
Leopold. A standard gauge track is
laid in the tunnel and electric mules
will be used in transporting the ore
To the rortal. Some form Of the cav
Ing method of mining will be used in
The future operations of the compa-
ny's mines. This is one Of the most
dangerous but at the same time econ
omical methods of ore extraction.
The water supply, which has been
the cause for much discussion since
the erection of mill was first an
nounced, is settled as it has been
found that sufficient quantity can
be pumped from the No. ! and No. .
shafts to run the mill and any other
of the operations demanding water.
II ut any time this supply is not large
enough pipe line from wells at the
head of the Mangas is planned to
furnish water.
Steel head frames are to be erect
ed at the No. and No. 3 shafts and
electric hoists installed upon the
completion of the power plant.
There are at present two hundred
men on the company's pay rolls en-
gagged in development work, excava-
ton, experimental mill work and 9th
er operations at Tyrone.
When questioned as to IN estimate
of ore blocked ont. Manager F.. NJ.
Sawyer of the Burro Mountain Cop
per Company said, "There is II suf-
ficient quantity TO warrant the con-
struction Of mill with thousand
ton daily capacity. AT present We
are not looking ahead to anything
greater in this type of mine Deyel-
opment work is being pushed steadily
at all parts of the workings. especial
~ in the Niagara tunnel where drifts
and wines are being driven. There
is at present one churn drill on the
property but two more will be added
within n short time.

construction work of the company
and is general superintendent of the
operations in the Burro mountains.
Mr.. Fraser Campbell is chief engine

the power plant at Tyrone.
