GOLCONDA COMPLETES
NEW ACTON PLANT
Concentrating Mill at Trial Run
on High Grade Proves
Satisfactory

KINGMAN. Ariz, oct. 2.-The first
section Of the Golconda mill, with a
capacity of forty tons a day, has been
completed, and trial runs made dur
ing the past week have proved highly
satisfactory. The plant is standard
concentrating mill, with crushers, rolls
jigs and Wiley tables.
Some idea can be gained of the rich
ness of the milling ore on the dumps
from the fact that the poorest milled
so far has concentrated about three
into one. Manager Boyle estimates the
total OF his milling ore already broken
in the slopes and on the dumps at
about 10000 tons, worth about IS ton.
The cost of milling should not exceed
50 a ton, so the dumps will probably
net about $1SO,O00. OF the above tom
mage 1000 tons will average S5 per cent
in zinc and will concentrate one and
one-half into one.
Work has been started on the sec
ond section OF the mill and eighty tons
a day will be handled by November /.
In the meantime shipping is contlnu-
ing steadily at the rate of 800 tons OF
4S per cent zinc ore month. UP to
the present time the Golconda has
shipped 1900 tons of ore, netting about
$275,000 above freight and smelter
charges. AS yet there has been no
stopping done below the fourth level,
which is only 300 feet deep, and the
amount OF ore in sight insureS steady
production for many years.
The Prosperity tunnel, which will
largely eliminate hosting in the Col
conda, is now 1000 feet long, and has
been in good ore for some time. The
face is still 800 feet from the known big
ore bodies of the Golconda, but from
the present showing a new shoot of
shipping ore Is expected soon.
STOPS DEVELOPMENT
In the Tub mine. owned by Boyle
personally, development work has been
stopped for the present. With a forty
foot width of fine milling ore, thous-
ands of tons of which are already
blocked out, Boyle has stopped further
work pending the erection OF large
mill for the treatment of the Tub ore
alone.
Although the Tub and Golconda are
adjoining mines, their ores are quite
different in character. Golconda ore is
a simple combination of lead and zinc
sulphides, which are easily separated
by 1igs, the Tub ore is rich in cop
per pyrites, from which zinc can be
extracted only by magnetic separators'
The copper pyrites, however, carries
better silver and gold values than the
Golconda ore, so that In the end II is
just as valuable.
Drifting east from shaft No. Q, on the
500 foot level of the Gold Road mine,
has disclosed still another ore shoot
with about seven feet of good milling
ore. The latest strike is the beginning
of the third shoot OF ore in the mine,
the first being HOO feet long, the sec
ond 1900 feet long, and each averaging
twelve feet in width. There are still
about 5000 feet of virgin ground with
excellent groupings The forty stamp
mill is handling about five and one-half
tons per stamp, which will be helped
by Chilean mills now being installed.
The Tom Reed mine paid its second
dividend of cents per share several
days ago. The ten stamps are crush
ing about forty-five tons per day, aver
aging a little over $40 ton. The
stamps of the old mill are to be moved
up to the new and will be put into
operation as soon as possible.
At the Ruth mine the new shaft, at
a depth of thirty feet, is In better ore
than that found in the old one at
similar depth.
