Large boulder-like masses of ore have a strike length of 40 feet. The ore is siliceous manganese oxide that is very discontinuous and variable in tenor. It is associated with greenstone and altered greenish sandstone. The ore bed strikes N30W and probably dips 20SW, with a maximum width of 5 feet. Quartz veinlets cut the bed. Another ore body is 10 feet long and 4 feet wide and is associated with greenstone and altered shale. Local rocks include rocks of the Franciscan melange.
