A former Au-Ag-Cu-Pb mine located in sec. 23, T8N, R10E, MDM, 1.2 km (0.8 mile) S of Enterprise, along Big Indian Creek and about 3 miles N of Plymouth (S of the Bay State Mine), on private land. The property is an agricultural patent of 130 acres. Operated prior to 1900, and intermittently from 1917 to 1935 (in the 1920's, 1933, 1934 and 1935). Owned by Eliza M. Kaiser. MRDS database stated accuracy for this location is 500 meters.
Mineralization is a quartz vein deposit hosted in greenstone and slate. The ore body is pinch & swell in form at a thickness of 2.74 meters. The quartz vein ranges from 2½ to 9 feet in thickness and contains pyrite-bearing quartz stringers. The slate host rock strikes N along a ½ mile wide belt. The ore vein, as exposed in the adit, is at the contact with the slate hanging wall and greenstone footwall. Local rocks include Mesozoic volcanic rocks, unit 2 (Western Sierra Foothills and Western Klamath Mountains).
Local structures include a fault exposed in workings shows minor offset in the quartz vein.
Workings include underground openings with an overall depth of 900 meters, and comprised of a 900 foot vertical shaft, 600 feet of drifts on the 300 foot level, and drifts 600 feet and 1,000 feet (?), a crosscut adit on the 500 foot level plus some drifts at the 800 foot level.
Production data are found in: Carlson, D.W. and Clark, W.B. (1954).
Some ore was produced prior to 1900. Some production was reported during 1933, 1934, 1935. The mine produced over $20,000 (period values) of Au & Ag during the period 1932 to 1935, plus minor Cu & Pb.
Analytical data results: Latest operations produced ore assayed at $6 (period values) per ton.
Since the last production was only a few thousand dollars, and no new ore was found, work was abandoned and the equipment was removed.
