The 150-ton capacity Copper Age
mill is expected to be in operation in
a few days Nearly all the machinery
has arrived and has been installed.
Workmen are now engaged in putting
the rolls in place and in adjusting
belts throughout the mill. The 100
horse power engine that is to provide
power to turn the mill machinery> will
be given tryOut some day this week.
To all appearances the mill has been
well constructed and is complete in
every way. The process used has not
been given test in a plant of this
size, but in the FL Paso plant it is
said to have given a high degree of
satisfaction.
In the Copper Age mine three shifts
are driving the lower main working
tunnel which is in 400 feet, and the
vein drifted on about 80 east and west
The vein was crosscut in each drift
about 20 feet back from the present
faces and the ore found to be of an
excellent quality and of a better width
than above
The OreshoOt was proven to be $40
feet in length on the upper tunnel
level, with the ore swelling in places
10 as high as seven feet Not all the
ore is of that width, of course, the
oreshoot frequently reducing to a few
inches, then swelling again to a foot
or perhaps several feet of good ore.
The company expects to press the
machine drills into service in both the
upper and lower tunnels this week, the
300-foot capacity compressor being in
readiness to provide pressure.
Foundations have been laid for
750-foot capacity compressor. which
has been ordered, but which has been
delayed in leaving the factory, like
machinery of all sorts
The Emerald Isle is having the cleo
trio power brought into its camp the
Desert Power and Water company
having a force of men setting poles
and stringing wire from their main
line, which passes within half mile
of the copper cOmpany's plant. The
electric current is to be used to assist
in precipitating the red metal and also
to aid in recovering the sulphuric acid,
which in the process used amounts to
quite an item and which is now COM
pletely lost. 1t is understood that
with the aid of electricity about so
per cent of the acid will be recovered.
The Emerald Isle company esti-
mates that the present proven ton
mage of ore is 100000 tons, which will
average 2.S5 per cent copper Their
tests show that a net recovery of %
per cent copper is being MOI
They have just completed fou4 large
teaching tanks which with present
equipment will furnish a capacity of
20 tons per day. A compressor and
power drills have been purchased to
reduce cost of mining and help in
crease the production.
The same people who made sue
cess of the Leviathan and who are
also operating the Cupel mine adjoin-
ing the Arizona Butte mine have the
destinies of the Emerald Isle in their
keeping and are going about it's bust
ness affairs in way that insures the
success of the property.
Erect Gailows Frame
Inc SdlONS frame at the 1uckahOe
has been erected and all is in readiness
for the hosting plant when it arrives
Pending. the installation of this ma
chinery, the 25-fOot shaft is being
squared up and timbered.
The Tuckahoe has a record as an
old producer of high grade ore, but
comparatively little work was done,
the deepest shaft on the property be-
ing only 100 feet deep. The principal
values are gold and silver, with here
and there some lead.
]. E. Carter, who with his associ-
ates is operating the Tuckahoe, is per-
sonally active in getting everything in
readiness for sinking and opening up
of the well-defined vein.
Rattlesnake Shaft
The Rattlesnake is sinking it's shaft
to the 200-foot level and now has it
down to point that gives it a depth
of 80 feet on the vein. Water is not
proving a source of trouble, the hoist
