A Au-Ag-Cu-Pb-U-Mo-Hg mining area located in secs. 7, 8, 14 & 20, T22S, R39E, MDM, 15 miles NE of Little Lake, and partially on the China Lake Naval Ordnance Test Station.
Mineralization is in part deposits of cinnabar in hot spring sinters. Cinnabar and metacinnabar line fractures in the sinter fumaroles and coat grains and fragments of opal. Most cinnabar is fine-grained, without crystal form, and is rarely abundant enough to give more than a pink tinge to the enclosing rock. Chloride of mercury of unknown composition is present. Obsidian in the district contains a suite of species.
