MINING OUTLOOK BRIGHT
Big Jim Gold Mining Company Will
Soon Start Mill
(Patagonian)

to believe that in a very short
time Patagonia will have a con-
sistent, real producer.
At the mine, Superintendent
Peterson has re timbered the
mine shaft from the collar to the
bottom. He has enlarged it
from compartment and a half
to two full compartments. A
working station has been con.
structed at the 100 foot level and
heavy rails have been laid
throughout the workings. Elk
traction raises have been run
into the ore and chutes installed
beneath these raises, and the
slopes have been prepared for
extraction Of ore.
5 While this work has been go.
ing on, a mill is being built. Big
Jim ores contain only lead and
silver, with some little copper,
so that the milling practice is a
comparatively simple one, in
view of there being no complex
ores to deal with.
The plant will have capacity
of, approximately Is tons per
day and will be OF the very latest
practice of concentration by flo.
tation. The flow sheet of the
mill has been carefully studied
and, starting from the gyratory
crusher, the ore goes to large
bin. From there it is fed to a
set of Davis rolls, and from the
Davis rolls the flow goes to a
five ty five Duco ball mill. This
ball mill is in closed circuit with
"a Dorr classifier. From the
classifier the coarser grade of
pulp will be sent over a set of
Whitley tables. The tailings
from the Whitley tables. will be
returned to the ball mill and re
ground to 100 mesh. This grade
of material will then be taken
from the classifier through K &
K. fotation machines. There
will be a ten foot roueher ma
chine and a nine foot tinisher in
the fotation room.
The Concentrates from the ia
b'es and from the fotation ma.
chimes will then be sent through
an Oliver filter, from which the
finished product will be taken.
Tests have shown that the ore
is very easily concentrated, and
it is expected that q ratio of ten.
to one can be expected.
At the present time the exca-
vations at the mill site have been
completed and the ore bin is al
most finished. The machinery
is being put upon the concrete
foundation and it is expected
that within a period of 20 days
the mill will be ready to turn
over.
It has been estimated that
there is probably ore to the ex.
tend of 81 .000.0 opened in the
slopes. The vein is very wide,
but the extend along it's length
is not yet known.
From many checked assays, it
is believed the ore will run $25.
90 per ton, if the values are
based on the present price of lead
and silver.
Since the company has at least
two years supply of ore opened,
it will be the policy of the man,
agement to get into earnings as
quickly as possible, rather than
to devote too much time to de-
velopment. When earnings com
mence, certain amount per ton
will be laid aside for the further
opening of ore reserves.
It will be remembered that the
present Big Jim company is a
continuation of the old Big Jim
Gold Mining Company that
opened a large mine in Oatman,
Arizona. The mine was later
sold TO the United Eastern Min
ing Company, which produced
from it some $5,O00,000.
KOLLBERG MILL IN OPERATION
F. B. Kollberg, a we'll known
mill man, has a mill in operation
in the Salero district and is max
ing his first shipment of concep.
trates TO the smelter. Lack of
water at first was a serious
handicap to operations, but this
difficulty has been met by sink,
ing a we'll in canyon near the
mill, which supplies ample water
for the mills needs.
