A Ag-Au occurrence/mine located 1.2 km (0.7 mile) SE of Randsburg, along the W canyon wall of Fiddler Gulch. Discovered in 1893. MRDS database accuracy for this location is not stated.

Mineralization is a hydrothermal vein deposit (Deposit model code: 151; USGS model code: 25d; deposit model name: epithermal vein, Sado; Mark3 model number: 28) hosted in rocks of the Silverton Volcanic Series (Rand Schist). The strongest veins in the system strike N80E and NW. Controls for ore emplacement included wallrock/fault planes. The area is characterized by Paleozoic shales, slates, limestones and calcareous sandstones that are intruded by serpentine, gabbro and granodiorite . Flat-lying schist is intruded by a batholith of quartz monzonite (Mesozoic Atolia) and numerous Miocene rhyolite pipes, dikes and sills. Associated rocks include Neoarchean rhyolite. Local rocks include Mesozoic granitic rocks, unit 3 (Sierra Nevada, Death Valley area, Northern Mojave Desert and Transverse Ranges).

Production data are found in: Hulin, Carlton D. (1925).
