WILL EXPLOIT
NEVADA COPPER
Delaware Capital Undertakes
Big Enterprise in Church
i'll County, Nevada.

A $50 900 deposit on a deal involving the
payment by a group of retired capitalists
in Wilmington, Del, of $4,000 TO Messrs.
Boyer, Gunnel and Uniacke, of LovelOcb,
New. for tWenty-seVen claims at Boyer,
/ Churchill county, Nevs da, assures the
launching OF a copper mi1ng milling ana
transportation project on a scale never
before attempted in Nevada The deal
was effected through the offices Of Gin
ton ID. Ray, after three years OF Ell
fort, assisted during the last eight months
by the well known metaliurgist and min
ing engineer, DR.. Carpenter who has an
international reputation. Within a Few
days diamond drill operations Will COM
mence on the grounds or the company
under the management Of MIR. Wright OF
the Seattle Diamond Drill company TO
test as far as possible the extent of the
copper deposit.
The project involves the probable ex-
penditure of Sf0.CO0000. and is to include
mining. milling and transportation opera
tons heretofore attempted nowhere out
side of Bingham. A 3.O00-ton capacity con-
centrating plant viii be erected, begin
ming operations with the first unit of
1000 tons. The projected mining plans in
volve stupendous mechanical operations.
A forty-mile railroad will be built from
the Southern Pacific southwark to the
scene of the mining and milling opera
tons, for the purpose of bringing in sup
plies and carrying away the concentrates.
al cost of not less than SSO0O0O.
The great Boyer copper deposit is a
duplisate Of the immense, enriched pOr-
phyry intrusion in Bingham canyon
where mountains are being leVeled with
steam shOvels. After eight months Of
careful work on the ground, DR.. Carpen-
ter reports the existence of an ore body
that may prove to be second to none
i'm the world, Between walls OF rhyOlitc
and trachite there is a mighty upthrust
of mineralized poTphyTy from 800 to loo
feet wide, that there is every reason TO
believe is all ore that viii mill al
good profit. This great intrusion or ore
extends the entire length of the district
and. being a primary occurrence Of ore
or the original magma from which all ore
comes, it is probable that. the values Will
be found as deep as the igneOus intrusion
itself. On the Treasury Box claim alone,
Dr. Carpenter estimates that above the
1O00-foot level are at least 20,000,oO0 tons
of good milling ore. He asserts that cop
per indications were found on every
claim Of the company examined and that
the probable amount of ore in the ground
owned by the company is beyond cOmpu-
tation.
Below the leached zone the ore con-
sists of pure grains of chalcopyrite dis
seminated through the pOrphyry, having
been formed as an original constituent
Of the igneous rock. 2S0-foot tunnel
and a Wine on the Treasury Box begin
and end in ore and penetrate beyond the
leached-Out zone into the unleacned or
unaltered zone Assays show that the
leached ores average from las to 10
per cent copper and that the unaltered
ores average from 3is to 5lz per cent
copper. In the leached zone are immense
patches and strips Of oxidized ores that
show a general average of 126S per cent
copper. Assuming that the lowest aver
age of ore Obtainabe will yield twenty
five pounds of copper per ton, the report
shows that with the facilities at hand at
Boyer a minimum profit Of $50 per ton
is assured with copper at u cents a pound
and 81 with copper at 10 cents a pound.
But there is every reason to believe that
the yield of copper in the unaltered zone
will be twice as great as this estimate.
There is sufficient water on the ground
to insure the operation of 3,000-tOn
concentrating plant and enough timber
within fifteen miles for all purposes.
The company organized to handle this
colossal project will be known as the
BOyer-Nevada Copper company. The pro
visiOna1 directors are: Dr. Franklin r.
Carpenter. Denver. president: II. r. Dur
kee. Chicago. vice president; Arthur Howe
Carpenter. Denver secretary and treas
urer. The company numbers among its
members men of national reputation in
industry and finance.
