An Fe-silica-Mn occurrence/prospect/claim located in the NE¼ sec. 20, T28N, R11W, MDM, 6.7 km (4.1 miles) WNW of Pony Buck Peak, on National Forest land. Owned by the federal government - Trinity National Forest (100.00%), California (1975). MRDS database accuracy for this location is not stated.

Mineralization is a Mn deposit hosted in chert. The ore body strikes N35W and dips 88E at 6 meters thick, 20 meters wide, and 100 meters long, and having a depth-to-top of 2 meters. It is a sedimentary deposit with an irregular and disseminated form. The primary mode of origin was oxidation and the secondary mode was metamorphism. Primary ore control was lithology and the secondary mode was bedding. There is no wallrock alteration. Conflicting information presented in MRDS: ore body width at 1.98 meters and a length of 9.45 meters).

The mineralized rock is white and grey chert, dipping steeply to the NE. It is 150 feet wide. Adjoining country rock is mainly sandstone and greenstone. The W contact of chert is against greenstone. Limestone is exposed 200 feet N of the northwestern-most chert. Brown sandstone lies along the E contact of chert, in places partially recrystallized, and in places resembling greenstone. Diorite outcrops 400 feet N of the main ore body. 4 types of Mn are: 1. Mn oxide; 2.) rhodochrosite, commonly coated with oxide; 3.) siliceous Mn in which Mn oxide is mixed; and, 4.) Chert stained with Mn oxides. The main ore body is 6.5 feet wide and 31 feet long. The principal mineral is rhodochrosite, but in places considerable rhodonite and bementite are present. Bementite, which resembles chert, may be an important mineral. Local rocks include Paleozoic marine rocks, undivided, unit 9 (Western Klamath Mountains).

Analytical data results: The ore grade is 18 to 22% Mn.
