A former Cu-Au-Ag-Zn occurrence/mine located in sec. 2, T8N, R4E, and in sec. 35, T9N, R4E, HM, 6.6 km (4.1 miles) N of Hoopa, along the Trinity River (eastern bank), on Indian Reservation land. Last operated 1966. Exploration by Eagle Pitcher Co. (1964). MRDS database stated accuracy for this location is 100 meters.
NOTE: The MRDS database contains a total of 3 files for "Copper Bluff." One of these pertains to a "Copper Bluff" in Glenn County. The remaining two (cited herein) pertain to the Humboldt County deposit, regardless of erroneous data in some of the MRDS files. The geographic coordinates provided in conjunction with the T&R values, plus the additional data (Hoopa Indian Reservation) were used to sort out the discrapant files.
Mineralization is a vein or bedded replacement polymetallic deposit hosted in schist. The ore body is a tabular-shaped replacement deposit which strikes N07E and dips 18E at a thickness of 2 meters, width of 35 meters and a length of 45 meters. Wallrock alteration is silicification and pyritization of an unknown degree. The primary mode of origin is hydrothermal. Primary ore control was bedding and the secondary control was lithology. Sphalerite occurs near the surface. The schist is pyritized. Local rocks include Paleozoic marine rocks, undivided, unit 9 (Western Klamath Mountains) and/or Jurassic marine rocks, unit 1 (Western Sierra Nevada and Western Klamath Mountains).
Workings include drifting and diamond drilling. NOTE: Workings had to be more extensive than this since this was a working mine. The topo map has an adit symbol for this locality; therefore, it is reasonable to presume that an adit is/was also present.
Analytical data results: 5% Cu; 14 - 17% Zn; 8 - 50 ounces Ag and $5.80 (period values) Au/ton and 0.5 - 1.5% Pb.
