Dec 07, 2005 (K R Kettles) - The area underlying the occurrence is composed of units of mafic metavolcanics and metasediments. All of these units strike to the northeast and have nearly vertical dips. The mafic metavolcanics are primarily composed of pillowed flows and stratigraphic tops are to the northwest. Metasediments, primarily composed of argillite overlie the metavolcanics. Thin units of chemical metasediments consisting of graphitic cherts and marbles are interbedded with the clastic metasediments. Silver is reported to occur in lenses and stringers of pyrrhotite in graphitic argillite.
