A former Mn mine located in the NW¼ sec. 23, T1S, R6E, HM, 2.2 km (7,300 feet) ESE of Mad River Rock, along Hale Creek, on Mad River Ridge, on National Forest land (located claim). Discovered and first produced in 1941. MRDS database stated accuracy for this location is 100 meters.

Mineralization is a Mn deposit hosted in Late Cretaceous chert. The ore body is 3.66 meters thick and 45.72 meters long. The ore body is a nearly flat-lying, massive, tabular lens 150 feet long and 3 to 12 feet thick, enclosed in Franciscan chert and sandstone. Near the W end, the ore body is 1 to 5 feet of buff or greenish chert interbedded with thinly laminated red shale. Near the E end the ore is separated from sandstone above by only 6 inches of white chert. Greenstone near the W end appears intrusive. Ore is mainly dark brown-reddish hausmannite, with some bementite and rhodochrosite. These are cut by veins of calcite, rhodochrosite, bementite and barite. Some Cu minerals, inesite, and manganiferous amphibole were present. Local rocks include Franciscan Complex, unit 1 (Coast Ranges).

Workings include unspecified underground openings. The mine consists of a series of cuts in a massive manganese orebody overlain by cherts and sandstones.

Collecting information: The open cuts were not productive of specimens. Down slope, in the stream bed, the collecting was much better. Some boulders had veins of opaque white calcite running through them and those that had little black "sticks" of Inesite growing into the calcite were what you were looking for. The black "sticks" were actually oxidized Inesite crystals. You would break up the boulders and try and extract chunks of matrix rich in Calcite shot through with Inesite, which you could haul back to the car a few km away. Later you would use a 10% water/nitric acid solution to etch away the calcite and expose the pink Inesite crystals. A few were barite pseudomorphs after Inesite. Other acids tended to tear up the Inesite and turn it quite white.
[Rock Currier 2010]

Analytical data results: The ore grade is 42% Mn,1% Fe and 21% silica.
