Arsenopyrite is very abundant here in large masses and occasionally in good crystals. Pyrite and quartz are also found here. The arsenopyrite is in a vein about 1000 feet long and 3 to 4 inches wide surrounded by a fine-grained, black phyllite of the Waits River Formation. The arsenopyrite is of hydrothermal origin, but the fact that only iron, sulfur, and arsenic are present is unusual.
