A former lode Au-Ag occurrence/mine located in the NE¼NE¼ sec. 1, T36N, R9E, and in the SE¼ sec. 36, T37N, R9E, and in the NW¼NW¼ sec. 6, T36N, R10E, MDM, 0.7 km (0.4 mile; 2,300 feet) SW of Hayden Hill (summit) and 1.1 km (0.7 mile) ESE of Hayden Hill (town), on the SW slope of the summit. Discovered by J.W. Hayden and S. Lewis in 1869. Owned by U.S. Gold Corp. and Amax Gold, Inc. (1990). MRDS database stated accuracy for this location is 500 meters.
Mineralization is a vein deposit (Deposit model: 104: Hot-spring Au-Ag), hosted in tuff. The ore body is comprised of veins that strike N45W; N38E and dip 75NE & vertically at a thickness of 7.62 meters and a length of 1,371.6 meters. The gold is extremely fine-grained as rounded particles associated with pyrolusite. There are other veins on the property as well. The manganiferous ore occurs in pockets in the veins. Very minor pyrite was found in one tunnel. The deposit is said to have formed in a hot spring environment during Miocene faulting and volcanism and is characterized by quartz-adularia veins, stockworks of veins and breccia zones cemented by silica. Rhyolite Alteration includes the somewhat silicification of rhyolite. Associated rocks include Pliocene basalt. Local rocks include Tertiary intrusive rocks (hypabyssal), unit 1 (Cascades Volcanic Field).
Local structures include E-W-trending fractures.
Related tectonic structure include the Modoc Plateau.
Workings include surface and underground openings, with a depth of 254.51 meters and several levels of drifting.
Mine dumps in the district were worked by leach heap methods during the 1980's.
