A former lode Au-Cr-Ag-Cu-Fe-Pb-Mn mine located in secs. 20 & 21, T37N, R7W, MDM, 1.0 km (3,300 feet) S of Carrville, on National Forest land. MRDS database stated accuracy for this location is 500 meters.

Mineralization is a replacement deposit hosted in dacite, porphyry and greenstone. Ore controls included shear zones. Meta-basaltic or greenstone dikes intrude dacite porphyry. Both are cut by later lamprophyre or vogesite dikes. The ore contained much free Au and was iron stained. Local rocks include Carboniferous marine rocks, unit 4 (Eastern Klamath Mountains).

Workings include surface and underground openings. Overburden was removed by hydraulicking. Several adits were driven, one 350 feet long, plus open cuts, raises and drifts.

Oxidized ore was treated by cyanidization. No other production record was found.

Production data are found in: Brown (1913).

Reserve-resource data are found in: Logan (1926).

Operating costs were about $2.40 per ton (period values).
