The Yellow Aster, or Rand, mine was discovered in April 1895 by Singleton, Burcham, and Mooers. The town of Randsburg quickly developed, followed by the supply town of Johannesburg in 1896. Both names were adopted from the profusion of minerals resembling those of the ranch mining district in South Africa. In 1907, Churchill discovered tungsten in Atolia, used in steel alloy during World War I. In June 1919, Williams and Nosser discovered the famous California Rand Silver Mine at Red Mountain.
