aOENIX, Ariz, Oct. N-The unset
ed condition of the copper market and
he worse than unsettled condition of the
copper share market are not reflected in
the operations of the big development
companies of the Globe district. At the
Globe Consolidated, the Superior & Bos-
ton and National Mining Exploration,
work is being pushed just as though cop
Fer were selling at rs cents and shares
at twice their par value. At the Gem
81 aft of the Globe Consolidated, 125 feet
remain to be sunk before the long looked
for prosecuting begins, the shaft meas
liring LOIS feet deep, with no change In
the formation At the Globe-Boston
shaft of the same company the south
drift on the $50 level has been started, but
work is progressing slowly until the
water problem is settled by the instaila-
ton of the pumping plant.
At the Superior & Boston active devel-
cpment work continues with undimin-
.shed forces on the three claims of the
company, which are being explored.
At the Iron Cap mine of the National
Mining Exploration company a full force
OF twenty men Is )eing worked. and this
force will be considerably augmented as
sc on as the pumping plant Is Installed
and sinking can be resumed. Lateral
work is still in progress on the 45O-foot
level and consists of both prosecuting
ond drifting.
The Buffalo-Arizona Mining company,
in the Black Canyon district, has COM
rleted the installation of an S0-ton cya-
ride plant w. D. Webster, general man
ager Of the concern, accepted the plant,
which will be started on steady run In
a few days. Five additional stamps will
be added to the five-stamp mill now on
the ground, in very short time and
other important improvements, involving
the outlay of a large amount of capital,
are under consideration. The property,
which is known as the Parker group, is
located three miles east of Turkey sta
ton, on the Bradshaw Mountain rail-
road.
Following instructions contained in
telegram from Milwaukee Superintendent
William McDermott has discontinued op-
erations on the Twin Buttes property.
Dry Process Succeeds
Newton c. westerfield. who with his
family. has made Phoenix his home since
a year ago last February, is the in
ventor of a dry concentrating machine
which If it will do what he claims for 1t
ought to revolutionize gold mining in
these parts and in many other countries
where water is scarce According to the
facts and figures of his experiments,
which have been conducted on rather
large scale in the field and not In the
laboratory, as so many such tests are, his
dry concentrating process will save a
larger percentage of gold than any other
plan of reduction yet invented. and
cheaper even than the wet processes.
1t is the contention of Mr.. Westerfield
that he has the only successful dry con-
centrating process known, all others hav-
ing been failures or but partial successes.
Neither should it be confounded with the
so-called dr. washers, for while 1t does
the same work and does 1t better it is
also designed to reduce quartz formations
with the assistance of good ore crush
ing machine.
Mr. Westerfeld has been engaged in
mining for the last twenty-three years,
having been in the machinery business
before that time.
No attempt will be made to describe
the machine except as to it's principles,
which are specific gravity, graduated air
currents and reciprocal motion instead OF
the knocking and jarring of the tanning
mill movement of the ole fashioned dry
washers or concentrators. The minerals
are thus precipitated more perfectly in
stead of being jolted away with the gang
matter In respect of air currents they
can be regulated to the character of the
material handled. If it is found they are
too strong they can be toned to any force
desired. A system of steel rods also takes
the place o. the old wire screens that be-
come clogged. so there is always an
opening for the metal to get through, and
its gravity. no matter how small the diff
ference, insures its saving The crushing
process is also gradual. The material is
reduced in size five different times in its
course through the machine and with
each reduction the values are taken from
the ensuing dust. SO that by the time the
fifth reduction is had there is mighty
little gold left in the dirt. The machine
is operated by a gasoline engine and the
expense is very small.
