A former lode Au occurrence/mine located in the S½SW¼ sec. 28, T41N, R9E, MDM, 1.6 km (5,400 feet) WSW of Schaffer Mountain (coordinates of record), E of highway 139, on National Forest land. Discovered in 1904. Owned by Don Koza, Nevada (1989). MRDS database stated accuracy for this location is 100 meters. Operated in 1929.
Mineralization is a vein deposit (Mineral occurrence model information: Model code: 151; USGS model code: 25d; Deposit model name: Epithermal vein, Sado; Mark3 model number: 28), hosted in Pliocene andesite. The ore body is a vein that strikes N42W and dips 55SW at a thickness of 3.05 meters and a length of 45.72 meters. Andesite is brecciated in the fault zone but the breccia is not abundant at the mine. The footwall contains phenocrysts of albite, hornblende and some quartz in a dark green groundmass. It is probably andesitic. The richest ore occurs along the footwall. There are veinlets of secondary quartz also. Local rocks include Tertiary pyroclastic and volcanic mudflow deposits, unit 9 (Cascade Range).
Local structures include a fault at the 200 foot level in the mine which displaces the vein to the S with a strike of N15W and a dip to the E.
Related tectonic structures include the Modoc Plateau.
Workings include surface and underground openings with a length of 304.8 meters and developed by a 225 foot vertical shaft with a 60 foot NE crosscut to the vein with drifts on the vein. An old, inclined shaft went to a depth of 300 feet with a 150 foot E drift on the 150 foot level and a 160 foot E drift on the 250 foot level. There are considerable other workings. In 1986 4 people were employed performing work of an unknown nature.
Production data are found in: Averill (1929).
Analytical data results: Assays ran $12-36 (period values) Au/ton.
