Mohave County miner., 1910-01-08
Production of Copper in 1893
A RECORD BREAKING YEAR.

the United States Geological Survey
from all plIlts kl)vn to produce
blister copper from domestic ores and
from all lake mines indicate that the
copper output from mines in the
United States in 1899 surpassed all
previous records.
The figures, which have been col
lected by B. S. Butler, of the Survey,
represent the actual production of
each company for eleven months and
include an estimate of its December
output. The November figures for a
few companies were not available and
these companies furnished estimates
for the last two months of the year.
According TO the statistics and estim-
ates received the output of blister and
lake copper was L.Il7,S)O,000 pounds,
As against 943.57O,72l pounds in 1908.
an increase of over IS per cent. This
not only exceeds the increase of any
previous year but it is considerably
greater than the total yearly increase
since 1891
OUTPUT OF LEADING COPPER-PRODUC-
ING STATES.
1t is impossible now to give figures
that represent accurately the distribu-
tion of the output among the States of
origin, but few general statements
may be positively made concerning
the leading cOpper-producing States
Montana shows a large increase, again
taking first rank, place lost TO Ariz-
ona in 1907. The production in Mon
tana will ne lrly equal or will possibly
exceed the States previous record out
put, 3ll - ,0)O polnds, made in 1905.
Arizona hDlds second place. with a
slight increase over the 2S9. .523. 900
pounds pr d iced in 1908. Michigan
also exceeded the 1898 production, DID,,
2S9,OOO pounds. Large gains were
made by Utah and Nevada, and CO.
f'rlia also increased IT'S output con-
siderably.
REFINED COPPER.
Statistics showing the output of re-
fine copper by plants in the United
States are not now collected by the
Geological Survey. Figures published
by the Copper Producers Association
indicate that the production of market
able copper from all sources, domestic
aud foreign, for the first eleven months
of 1909 will exceed l,40O. 200, as
against 1,l6l, l76,OS5 pounds in 1905
Statistics showing domestic deliveri,
for the first eleven months of the year,
as given by the Copper Producers
Association, indicate a consumption
of copper in the United States consid-
erably greater than the previous rec
ord consumption-6S5,O 100000 pounds,
in 1856.
EXPORTS.
Estimates based on figures for the
first eleven months, published by the
Bureau of Statistics and also by the
Copper Producers Association, in
dicate that the exports of copper will
surpaSs by several million pounds the
exports for 191S-66l, $40, l27 pounds.
IMPORTS.
According to the Bureau of Statisti,s IS,
imports Of pigs, bars, ingots, plates,
and old copper for the first eleven
months amounted to 2l3, 100, 2Sl pounds,
and the copper content of ore matte
and regulus imported amounted to A.
70S,4S2 pounds. If the imports for
December were equal to the average
monthly import for the first eleven
months the amount of copper entering
the United States for the year was
about 3ll 100000 pounds, as against
2lS, 705. 4S7 pounds in 1908.
STOCKS.
Stocks Of refined copper in the
United States show a considerable in
increase over those of January l, 1909.
but the accumulation occurred for the
most part during the first half of the
year. European stocks, however. have
increased rather uniformly throughout
the year and at the close were prob
ably nearly double those of January l,
1909. The price of copper has remain
ed close to l3 cents throughout the
year, the average monthly New York
quotation for electrolytic copper being
little under l3 cents.
MINE DEVELOPMENT.
Mine development has been active
in most of the important camps, but
especially so in the deposits of dis
