A former lode Au occurrence/mine located in the SE¼ sec. 6, T12N, R10E, MDM, 2.6 km (1.6 miles) NNE of Greenwood. Operated around 1894. MRDS database stated accuracy for this location is 1,000 meters. Reported to be 1 mile NE of Greenwood, which is in the SW¼ section 7, NW corner sec. 18. References show this mine in sec. 5 & 6, but this does not seem likely if the geographical description is correct.
Mineralization is a vein deposit hosted in slate. The ore body is 6.1 meters in thickness. The vein is 20 feet wide. A serpentine dike runs a short distance back of, and parallel with, the vein. The footwall is highly mineralized. Contains 3,000 feet by 600 feet (?) on same course as the Idlewild Mine (Taylor - section 21). The sulfides carry the Au. The surface of the outcrop is Au-bearing, as are all ravines heading toward it. Local rocks include Jurassic marine rocks, unit 1 (Western Sierra Nevada and Western Klamath Mountains).
Workings include underground openings with a length of 365.76 meters. Developed by 4 crosscut adits at 200 to 400 feet in length (developed by 4 tunnels 275, 325, 400 and 4,200 feet long - locations may be later known by different names). Some ground sluicing was being done in the 1890's.
No production record was found.
