Washington.-In 1918 there was a
record mine production of gold, silver,
copper, lead and zinc In Arizona, ac-
cording to preliminary figures of ".
C. Heikes of the United States Geo
logical Survey. The total value of the
mine output was about ST. 100000, an
increase of nearly six per cent over
the value of 1912, which was $67,05O,-
7S4. The copper output was valued
at nearly s64,O0O,O0O; the gold at
about s3,94S,000; the silver at more
than s2,265,000; the lead at S612, 1000
and the zinc at 100000.
The mine yield of gold in Arizona
in 1913 was more than 1000 ounces.
an increase of five per cent over the
output Of 1912. which was 1Sl,996.9l
fine ounces. OF this total, over AZ
per cent was taken from siliceous ores
and most of the remainder came from
copper ores, which are undoubtedly
the source of the increased gold out
put in 1919. The three largest pro-
ducing gold mines were the Tom
Reed, Gold Roads. and Vulture. The
Tom Reed output was about the same
as in 1912, the Gold Roads had a
slight increase. and the Vulture sub
stantial increase. In Yuma county op-
erations were resumed at the La For
tuna mine.
The mine production of silver in
creased about per cent, amounting
to mere than 3,773.0OO ounces, against
3,490,3S7 ounces in 1912. Most of the
silver was derived from copper ore,
but In 1913 the increase is due large
ly to shipments of lead ore and concen-
tratcs from Cochise and Mohave coun-
ties. Much silver also comes from
siiiceous ore. About 500 tons of ore
per month was shipped from the
Tombstone property and large ton
mage Of old tailings was taken from
the Commonwealth dump. A 35O-ton
cyanide mill at this property was COM
pleted during the year.
With mine production of about
Ala, ,593, 900 pounds of copper liz 1913,
Arizona led all other copper-producing
states. The output in 1913 shows an
increase of more than 49,ODO,OCO
pounds, or about IL per cent over
that of 1912, which was 365,03S.649
pounds. As the price of copper was
slightly lower in 1913, the value of
the metal increased only about 3d.
100000. There were IL active copper
smelling plants in the state, and ore
ard concentrate were also sent TO g
copper and lead plants in other states.
OF the former, the greatest increases
in output were made at the Hayden,
Calumet G. Arizona, Copper Queen,
Old Dominion, Consolidated Arizona
aud Swansea plants AT the United
Verde and Detroit plants there was
little change from the figures of 1912.
Those making less copper were the
shannon, Arizona Copper and Pioneer
plants. New plants were completed
by the Arizona Copper and Calumet
& Arizona companies, and another
was In course of construction for
United Verde ores. The disseminate
ed copper mines in ella, Pinal and
Greeniee counties yielded approx
mately las, 100000 pounds of copper.
Included in this estimate of copper
produced are the outputs of the Mi
ami, Ray, Arizona Copper. and Detroit
mines. The Miami product did not
greatly exceed that of 1912. The 5000
ton concentration plant was active
and the product went mostly to Can
anea, Mexico. The international Smelt-
ing & Refining Company Will build a
copper plant a Miami to treat the
ore and that from the Inspiration
mine. Test plants using the flotatf0n
process were operated at the Miami
and Inspiration as the saving by con-
centration alone is not sufficient. The
Ray Consolidated Copper Company
greatly increased its output, from
nearly 36,00O,00O pounds of copper in
1912 to about 52,000,000 pounds in
1918, treating 5000 tons of ore per
day. Production from Yuma and
Pima counties was not what 1t could
have been. since the Swansea and
Pioneer plants were operated only a
few months. At Globe greatly in
creased shipments were made from
the Superior & Boston. Iron Cap and
Black Warrior mines, and in Pinal
county from the Magma mine.
The mine production of recoverable
spelter was about 100000 pounds,
valued at 100000, which was an in
crease of about 100000 pounds, or
nearly 4 per cent. over the production
of 1912. On account of the lower
price paid for the metal, the total
value decreased more than 100000.
The Golconda mine, in Mohave coun-
ty. formerly the largest producer, was
making shipments of zinc ore and con-
centrates only part of the year, and
therefore had greatly decreased out
put. Much ore was, however, shippe
from the San Xavier mine in Pima
county and much concentrate was
made from Mohave county ores milled
at Needles.
