A former Hg-Sb mine (initially mined for Sb) located in sec. 5, T12S, R7E, MDM, 2.0 km (6,500 feet) SE of Antimony Peak (coordinates of record). This mine was the principal producer of Hg in the district. Started 1870 and closed 1880. Reopened 1912-1918, 1920-1947 & 1955-?. Owned by the Stayton Mining Co. and R. B. Knox (timeframes = ?). MRDS database stated accuracy for this location is 10 meters. Alternate coordinates provided: 36Β°54'49"N, 121Β°13'21"W.

Mineralization is a Pliocene Sb-Hg deposit hosted in basalt. The ore body is irregular in form, strikes N, dips 58W at a width of 22.86 meters and a length of 76.2 meters. Ore controls included fractures. Alteration is local (kaolinization of the basalt). Local rocks include Tertiary volcanic flow rocks, unit 1 (Quien Sabe-Burdell Mountain).

Local geologic structures include parallel fractures.

Workings included underground openings and were 80 meters deep on an inclined shaft. Their overall length was 487.68 meters and the overall depth was 76.2 meters. The old workings are largely inaccessible.

Production information: Produced 390 flasks of Hg at 34.7 kg/flask (1920-1947); 1,000 flasks (1870-1880).

Production statistics: 1962: ^2-40 pounds/ton Hg. Recovery grade: 10,630 grams/metric ton.
