TOFLOAT CONCENTRATES
DOWN ROOSEVELT LAKE
Plan of Roosevelt Lake Copper Com
pany May Include Fleet of 5arges
on Reservoir

ROOSEVELT, Ariz. Oct. o.-Trans-
fleet of barges on the Roosevelt reser-
voir is being considered by officials of
the Rooselevt Lake Copper company
which is developing sixty claims along
the Mazatzal mountains. Site for a
landing has already been selected near
Cline's ranch at the Tonto creek end
of the reservoir. Here the concentrates
can be dumped from auto trucks into
the barges, which will then be towed
down the lake to point near Living
stone, where they will again be trans
ferred to auto trucks and shipped to
Globe or Miami for smelling purposes.
From Reno Pass at the east end of
the company's property, a good auto
road leads to the north end of Roosevelt
Lake. but from there to the dam the
road is steep and winding. 1t would be
much simpler and cheaper, engineers
say. to dump ore or concentrates into
barges and tow them down the lake to
Livingstone than to make the haul
ground the shore of the lake. By using
steep banks at both ends of the lake,
the effect of a rise or fall in the wa
ter level could be avoided and ship
ment by water could go on regardless
of the height of the reservoir.
Another plan for the shipment of
concentrates that is being considered
is the building of an auto road from
the property to Mesa on the Arizona
Eastern. Surveys for the proposed
road show uniform grade, with
maximum of 1875 feet to the mile. In
view of the fact that the survey for
the proposed Arizona Extension rail-
road from Clarkdale to Mesa passes
within fifteen miles of the property,
officials of the company are inclined to
believe that shipping from the tunnel
on the west side of the Mazatzal range
could be made more cheaply by auto
trucks to the new railroad, or by build
ments of high grade smelling ore and
concentrates from the east end OF the
big ledge could be made by boat down
Roosevelt Lake.
Shipping ore of a good grade has
been struck on claim No. 30 at the
east end of the Humdinger ledge, which
1Ra1o+zo1c OF almost right
angles. The ledge appears to cut the
mountain from base to base, rising
2OO0 feet obve the tunmel site on the
west. 1t is over 100 feet in width, and
engineers who have examined the prop
erty say that it contains one of the
largest bodies of copper ore in Arizona.
The latest strike was made about two
miles from the No. 1 claim, where the
shaft has been sunk to depth or lSO
feet. Here the company has about 70
tons of five per cent copper ore on the
dump, and several tons of chalcopyrites
and glance, running as high as 20 per
cent in copper with values in gold and
silver. Assays of $3.50 a ton in gold
alone have been secured from the
surface outcrop on one of the claims.
In order to determine what method
of concentration to install, Robert n.
Williams of Tempe, president of the
company has shipped samples of ore to
the Hayden mill of the Ray Consol1dat-
ed Copper Company. and to the Hay
den smelter Inhalation of concen-
trating plant on the company's proper
ty where there is an abundant supply
of water and timber. has been advised
bv a number of competent engineers
who have examined the Humdinger
group.
