COPPER EXPERTS
WILL VISIT Mine
l.. ID. RICKETTS, AND OTHERS
ARE SOON TO INSPECT
PROPERTY

DR.. l.. d. Ricketts,, general man
ager of the Green Cananea Copper
company, with Thomas F. Cole. VIM.
B. Thompson ana perhaps other d.
rectors of Consolidated Copper
mines, are expected to arrive soon
to inspect the property. says the Ely
Expositor. More definite informa-
ton as to the plans of the company
are looked for at that time.
Recommendation was made by
General Manager Gray of the Consol-
idated Coppermines company, in his
annual report read at the recent
meeting of the stockholders, that an
experimental plant be established in
the Giroux mill at Kimberly. He
suggests that the plant be operated
for about six months to determine
the best method of concentrating and
teaching the ores found on the prop
erty in order that n may be devel-
oped and adopted to be installed In
a plant for handling the ores on a
large scale at an early date. This
was the plan adopted by the Nevada
Consolidated at the Ruth mine be-
fore the construction of the Steptoe
plant was decided upon and Is n of
the reasons why the company has
been so successful in earning big
profits by it's mining operations. Re-
ports from Kimberly state that pre-
parations to utilize the Giroux mill in
this manner have already been
started.
Though it Is but a few years since
the first experiments were made by
the Nevada Consolidated. great i'm
provements in methods of handling
low grade %porphyry r e have been
made. and some Of the new methods
promise to prove very much more
profitable than the old. Improve
ments have been made in concentrate
ing machinery by the use of which a
higher percentage of saving can be
made. The oil fotation process,
which was originated in Australia
and as adapted to conditions in the
United States, may very likely be
found the method by which the
greatest saving of the values can be
made. according to reports of ex-
detrimental work with similar por-
phyry r The f1otatiOn process
is being tested by the Nevada Con.
at McGill and prediction is made
that a new plant will be erected
there in the near future for the hand
ling of shines from the mill. No de-
tails as to results obtained there
have been made public, but from the
fact that experiments have been
conducted for a number of months
it is inferred that the oil process
holds promise of being successfully
adapted to use here.
A fleet of six churn drills is being
operated on the Giroux group and
different parts of the proper
ty are being prospected to great
depth. Drills have been set up again
over the caved area of the Morris
below the working from which ore
was extracted by the caving system.
There are reports circulated but I'M
confirmed that steam shovel opera
lions may be begun on new ground
very soon. And in this connection
it is said that on account Of the large
percentage of moisture in the ore
that is being mined by the Nevada
Con. from the Liberty pit and from
the Ora claim of the Giroux, before
actual shovel mining is undertaken
by the Coppermines the area between
the Morris and new GirOux shaft will
be penetrated by a level 1000 feet
deep from the new shaft on the west
side. There is a difference Of about
1000 feet in the water level on the
east and west sides of the ridge al
Kimberly, and it will ave money ia
drain the porphyry deposits throu' i.
the deep shaft; also it will prev ent
the ore freezing on cars in the winter
when the company does get to pro-
ducing on a large scale.
At the old Coppermines property
forty-eight men are on the payroll
and, divided into three shifts, they
are pushing the development of tina,
section of the Consolidated holdings
with vim and energy. The operations
are conducted through the Mime
sofa shaft and everything is working
smoothly.
