Twenty-four
States and Territories and the Philippine Islands contributed to the
production of silver in 1910. Or these there was increased output in 14
and decreased production in 11. The main increase, 2,246,800 ounces,
was in Nevada; but there were also increases of 454,800 ounces in New
Mexico, of 271,100 ounces in Idaho, of 248,400 ounces in Montana, of
132,100 ounces in Arizona, and of 129,700 ounces in Washington. The
largest reported decreases were as follows: In California, 513,300
ounces; in Utah, 105,200 ounces; and in South Dakota, 75,700 ounces. In
no other States or Territories was the increase or decrease as much as
50,000 ounces. The silver production continues to be mainly from dry or
siliceous gold-silver ores, copper ores, and lead ores, in the order
named; but the increased output of 1910 was chiefly from the
first-named class and to a smaller extent from zinc ores and from
lead-zinc ores, as the production from all other ores declined. The
silver-mining industry as such has declined to relatively small
proportions in the United States; but as a by-product of the ores
mentioned silver production was notably active in 1910.
In
the world's output of silver Mexico still leads, with an output of
approximately 72,500,000 ounces in 1910, and the United States remains
second, with 57,137,900 ounces, followed by Canada with a production
of nearly 32,000,000 ounces.
The average monthly price of silver in New York in 1910 was as follows:
