In leading up to Arizona's centennial, Feb. 14, 2012, we'll reprint a story or excerpts each day from the Arizona Daily Star or Tucson Citizen archives.
Dec. 12, 1912
The copper industry in the United States has shown a notable growth, according to the United States geological survey. In 1845, when important production of copper in this country practically began, the output was but 224,000 pounds, but it increased 100 per cent the following year and gained by rapid strides until 1850, when the production was 1,466,000 pounds. In 1870 it was 28,224,000 pounds; in 1890 it was 259,763,092 pounds; in 1900 it had increased to 606,147,116 pounds; in 1909 it had passed the billion mark, with 1,029,951,624 pounds; and in 1911 was 1,958,201,285 pounds of which 56 per cent was the output of the United States.
It is noteworthy that, unlike areas producing most other metals, not one of the leading copper districts of the United States, several of which have been active producers for a period of 30 years or more, has been worked out or showed a marked decrease in its ability to produce copper.
Twelve districts situated in eight states have each contributed over 100,000,000 pounds to the copper output of the country, or a total of 94 per cent of the whole output of the United States since 1845. Four of these districts are in Arizona, two in California, and one each in Montana. Michigan, Nevada, New Mexico, Tennessee and Utah. Two districts stand out prominently, the Butte district, Montana, which has contributed over one-third of the output of the country and the Lake Superior district, Michigan, with a production of a little less than one-third of the total output.
