Uranium Mining in Utah - White Canyon and Monument Valley Districts

White Canyon and Monument Valley Districts

Uranium associated with copper mineralization at the White Canyon district in was identified in 1920, but production did not begin until 1946. The geology is similar to that of the Monument Valley uranium district 40 miles to the south which straddles the Utah/Arizona state line (see Uranium mining in Arizona). Uranium occurs in the Shinarump Member of the Triassic Chinle Formation. Primary ore minerals are uraninite and coffinite. Through 1965, the White Canyon district produced 10 million pounds of U3O8. On June 29, 2012, Energy Fuels acquired the Daneros mine from Denison Mines in Utah's White Canyon District. Energy Fuels produced from the Daneros mine until October 2012, at which time the mine was placed on standby, care, and maintenance.

Famous quotes containing the words white, canyon, monument, valley and/or districts:

    He thought that I was after him for a feather—
    The white one in his tail; like one who takes
    Everything said as personal to himself.
    Robert Frost (1874–1963)

    In a world that holds books and babies and canyon trails, why should one condemn oneself to live day-in, day-out with people one does not like, and sell oneself to chaperone and correct them?
    Ruth Benedict (1887–1948)

    I hope there will be no effort to put up a shaft or any monument of that sort in memory of me or of the other women who have given themselves to our work. The best kind of a memorial would be a school where girls could be taught everything useful that would help them to earn an honorable livelihood; where they could learn to do anything they were capable of, just as boys can. I would like to have lived to see such a school as that in every great city of the United States.
    Susan B. Anthony (1820–1906)

    I will frankly declare, that after passing a few weeks in this valley of the Marquesas, I formed a higher estimate of human nature than I had ever before entertained. But alas! since then I have been one of the crew of a man-of-war, and the pent-up wickedness of five hundred men has nearly overturned all my previous theories.
    Herman Melville (1819–1891)

    Cities need old buildings so badly it is probably impossible for vigorous streets and districts to grow without them.... for really new ideas of any kind—no matter how ultimately profitable or otherwise successful some of them might prove to be—there is no leeway for such chancy trial, error and experimentation in the high-overhead economy of new construction. Old ideas can sometimes use new buildings. New ideas must use old buildings.
    Jane Jacobs (b. 1916)
