It is locality 112 of Winkler and others (1981 [OFR 80-892-B]).

Geologic setting

Geologic description

Iron-stained greenschist and calc-schist rocks, tentatively correlated with the Paleozoic Skolai Group (Winkler and others, 1981 [OFR 80-892-B]; Winkler and others, 1981 [OFR 80-892-A]), have been prospected with dozer trenches (U.S. Bureau of Mines, 1980; Winkler and others, 1981 [OFR 80-892-B]). Pyrite, barite, and possibly chalcopyrite are reported. The age and type of deposit are not known.
