Comments on the geologic information

  • Geologic Description = Mulligan (1974) described this occurrence as a quartz vein, about 2 inches thick, which cuts a chlorite schist. The vein contains minor goethite, malachite, and a trace of zinc (the zinc mineral is not specified). Float in the area contains traces of malachite and possibly chalcopyrite. The country rocks are Devonian black slate, phyllite, and phyllitic siltstone (Brosgi and Reiser, 1964). A body of greenstone is mapped about a mile to the east.
