Comments
Comment (Workings): Workings / Exploration = An 8-foot-deep shaft and a 60-foot-long adit have been driven on this prospect (Anderson, 1947).
Comment (Reference): Primary Reference = Anderson, 1947
Comment (Geology): Geologic Description = An 8-foot-deep shaft and a 60-foot-long adit explore discontinuous stibnite lenses and stringers up to 1-foot wide in contorted mica schist (Anderson, 1947). Some stibnite is described as forming tiny stringers and pockets in the folds of the schist. Bedrock in the area is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Comment (Deposit): Model Name = Stibnite lenses and stringers in mica schist; simple Sb deposits? (Cox and Singer, 1986; model 27d).
Comment (Exploration): Status = Inactive
