Geologic setting

Geologic description

Capps (1916) reports quartz veins present in Mesozoic age greenstone and greenstone tuff with minor amounts of interbedded shale of the McHugh Complex. The thin, auriferous quartz veins also carry pyrite, galena, and chalcopyrite. One 2 inch thick vein that strikes N 60 W and dips 75 SW is intersected by an 8 inch thick vein that strikes N 77 W and dips 60 N. Assays as high as 1.84 oz/ton Au.

Production and reserves

Workings or exploration Explored by several short adits. Assays as high as 1.84 oz/ton Au, reported as $38/ton, with gold valued at $20.67/oz (Capps, 1916). Some ore may have been mined, but not shipped, in 1917 (Capps, 1919). Martin (1920) reported discovery of chromite, in 1918, in Peters Creek. Rose (1966) reported a local prospector reported finding jade in Peters Creek.
Indication of production Undetermined
