Groom Lake (salt flat)

Lead and silver were discovered in the southern part of the Groom Range in 1864, and the English Groome Lead Mines Limited company financed the Conception Mines in the 1870s, giving the district its name (nearby mines included Maria, Willow and White Lake). The mining claims in Groom were acquired by J. B. Osborne and partners and patented in 1876, and Osborne's son acquired the interests in the 1890s. The claims were proved in 1916 when two companies began working their mines; that work continued until 1918, and resuming after World War II until the early 1950s. ==References==
