Uranium-Bearing Nickel-Cobalt-Native Silver Deposits, Black Hawk District, Grant County, New Mexico
From introduction: Mining began in the Black Hawk (Bullard Peak) district in 1881 when high-grade silver ore was found at the Alhambra mine. Most of the silver produced was native silver, associated with nickel and cobalt arsenides and sulfides. In 1920 pitchblende was recognized on the dumps of some of the old mines, and since 1949 the district has been of interest as a possible source of ores that contain uranium, nickel, and cobalt.
