A Cu-Zn-Fe-Pt-Ti-Cd-Au-Ag mine located in secs. 26, 27, 34 & 35, T33N, R6W, MDM, 0.7 km (2,300 feet) SE of Iron Mountain (town), 1.0 km (3,400 feet) SSE of Iron Mountain (summit) (coordinates of record), about 4 miles NNW of Kerwick and 9½ miles NW of Redding, on private land (mixed ownership ?). Discovery year was 1865. First year of production was 1879. Last year of production was 1962. Production years included 1897-1919, 1925, 1928-1930, 1943-1947, and the late 1950's to 1962. Owner-operator was Stauffer Chemical Co. and Iron Mountain Mines (1956-1977) (100.00%), California (1978). Owner was Iron Mountain Mines, Inc. (1985). MRDS database stated accuracy for this location is 10 to 100 meters.

Mineralization is a massive sulphide deposit (Deposit model: Model code 184; USGS model code 28a; name: Massive sulfide, kuroko; Mark3 model number 93), hosted in rhyolite. The deposit is comprised of several ore bodies, including: The Old Man; Hornet, Mattie, Richmond and Brick Flat ore bodies. Ore control was folds, a thick cover of shale (Early to Late Devonian), and pre-mineral faulting which may have provided channelways for mineralizing fluids. The primary mode of origin was hydrothermal and the secondary mode was contact metasomatism. There is moderate wallrock alteration (intermediate argillic; sericitic and pyritization, silicification of shale lies stratigraphically above the deposit. Mineralization is Early Devonian. Pyrite and chalcopyrite are found in approximately equal amounts. Local rocks include Paleozoic metavolcanic rocks, unit 1 (Eastern Klamath Mountains).

Regional Folds: Local major post-mineral faults are: Scott, Camden, and J Faults. The Camden also had pre-mineral movement. The Scott fault zone is 3-5 feett wide with many anastomosing slickensides and dark-gray to white gouge. The Scott is a normal fault, dipping 50NE, with a 250 foot dip-slip displacement. The Camden fault zone is 50 feet wide at the 2,600 foot level.

Workings included an open pit.

Assay analyses results: 1947: (1897-1947): 2-5% Zn, 2-7.5% Cu, 0.04-1 oz/ton Ag, 0.001-0.02 oz/ton Au.

Cumulative Cu production entries are for flotation plant. Copper ore of the Old Mine (Old Man ?) ore body, disseminated Cu.

Silver was discovered in gossan in 1879. The deposit was mined for sulphur during the late 1950'S to 1962. The Iron Mountains Mines, Inc. began engineering studies for a $20 million in-situ mining operation designed to recover Cu, Zn, and precious metals in 1985.

The iron which was mined was used in cement (all of it?). Pt was reported in smelter returns from Iron Mountain (Eilers (1913)).

Production and reserves data are found in: Kinkel et al (1956) Society of Economic Engineers field trip notes.
