COPPER REVIEW
FOR LAST YEAR

Statistics and estimates received by
the United States geological survey
from all plants known to produce blis-
ter copper from domestic ores and
from all Lake mines indicate that the
copper output from the United States
in 1911 exceeded that of 1910 and
nearly equalled the record production
of 1909.
Smelter Production,
The figures showing smelter produc-
tion from domestic ore, which have
been collected by =. $. Butler, of the
survey, represent the actual production
of each company for eleven months
and included an estimate of the De-
cember output. The November figures
for few companies were not avail
able and these companies furnished
estimates for the last two months of
the year. According to th statistics
and estimates received, the output of
blister and Lake copper was l,O9l ,554,-
900 pounds against 1850, ,159, ,509
pounds in 1910 and 1,092,95l ,624 in
1909.
Refined Copper
Statistics showing the output of re-
fined copper by plants in the United
States are not collected by the geolog-
ical survey at this time. Figures pub
ilished by the Copper Producers asso
citation for the first eleven months of
1910 indicate that the production of
marketable copper by the regular re-
fning plants from all sources, domestic
and foreign, will amount to about L.
42s, 10000 pounds, against 1853
100000 pounds in 1910.
Stocks.
Stocks of refined copper held in the
United States on January /, 1912, are
probably somewhat less than on Janu-
airy l, 1911, and foreign stocks are
also less. Both domestic and foreign
stocks have been materially reduced
since the middle Of the year.
Consumption.
Statistics showing the domestic de-
liveries for the first eleven months of
the year, as given by the Copper Pro-
ducers' association, indicate con-
siderable decrease in domestic con-
sumption compared with 1910. 1t may,
: however, exceed 7O0,000,00o pounds.
Prices.

trolytic copper for the year showed
further decline from the average fol
1910. The average for 19l1 was near.

Arizona.
, For 1911 Arizona again holds first
place among the copper-producins
states, but the output will hardly
equal that for 1910, viz, 297 ,25000t
pounds.
The Bisbee district was the largest
, producer, with an output of about
1873 100000 pounds, a marked decrease
from the l42, 100000 pounds produced
in 1910. A part of this decrease wa.
due to the stopping of shipment by the
ShattuckArizona mine during the later
part of the year. Development dis
closed some new and important ore
bodies in the district. The Calumet 4
I Arizona and Superior & Pittsburg com
panies were consolidated and the new
\ company began the construction of {
new smelter. The Copper Queen com
Ipany added a ealcining and reverbera
tory plant to its smelter. Plans were
! initiated for the construction of ;
a smelter by the Shattuck- Arizona com
r pany.
: The output of the MoreneiMetcal1
l district will probably show a slight de
g crease from the 73,154,000 pounds pro
I duced in 1910. The Arizona Coppe
t company has under construction a new
. smelling plant at Clifton.
, The Globe Miami district produced
about 100000 pounds, compare,
!, with 27,600000 pounds in 1910. Th'
large increase is due to the produc
!, tion from the Miami area. The frs
unit of the Miami mill started il
, March and successive units later, fv,
of the six being in operation at tn,
+, close of the year. Large addition
$ were made to the ore reserves of th
district, specially by the Inspiration
and Live Oak companies, and import
ant development work was carried ol
l by other companies. Development wa
also active in the Globe end of th
district.
! In the Jerome district the output o
the United Verde mine viii show
slight decrease from the 3s,660,00
, pounds produced in 1910. The Unite,

9 The Humboldt smelter of the Con
I solidated Arizona Copper company wa
operated till November and theI
closed.
The Mineral Creek district entered
I the list of active producers during the
year. The first unit of the Ray Con
I solidated mill was started in March
t and at the close of the year five OF
: the eight units were in operation. A
smelling plant is under construction al
Hayden by the American Smelling
{ Refining company. This will be ready
for operation about April, 1912. The
: development and blocking out of ore
a was continued, especially by the Ray
Consolidated and Ray Central com
$ panies.
