A former lode Ag-Au-Zn-Cu-Pb mine located in secs. 17, SE¼ sec. 18, and secs. 19-20, T31N, R6W, MDM, 2.3 km (7,400 feet) ENE of Grouse Mountain (coordinates of record), along South Fork Clear Creek, and about 4 miles NW of Igo. MRDS database stated accuracy for this location is 500 meters.
Mineralization is a vein deposit hosted in granodiorite. The ore body strikes N60E and dips almost vertically at a thickness of 0.91 meters. Controls for ore emplacement included fissures. Local rocks include Mesozoic granitic rocks, unit 5 (Klamath Mountains).
Workings include underground openings with a length of 244.75 meters and an overall depth of 46. 63 meters. Development was confined to the Big Dyke claim.
Analytical data results: Assayed at $20 - $400 Ag/ton (period values).
