Cinnabar occurs in the breccia vein in fractures and shears that cut the chalcedony. A small amount of stibnite occurs in a breccia zone in the slope above the mercury deposit. A short trench and adit SW of the shaft explores a locally silicified rib of andesite tuff which trends N 65 W, dipping 70 NE, where cinnabar fills fractures and open spaces in silicified andesite.
