Location: This prospect is located on southeastern Unga Island and represents an old claim block on the creek draining the Apollo mine site. It is approximately 1,600 feet northwest of the head of Delarof Bay and 1,500 feet east of the Apollo mine adit portal (Wilson and others, 1988, locality 41). The location is accurate to within 1,200 feet.
Geology: This prospect is a vuggy, oxidized quartz vein that strikes N 38 E and has a strike length of approximately 500 feet (Wilson and others, 1988). It occurs in volcanic rocks of the late Eocene to early Oligocene Popof volcanic rocks (Wilson and others, 1995). The vein is exposed in a short adit and may be the southwestern continuation of the Sitka fracture system (Wilson and others, 1988). Sulfides present in the vein include chalcopyrite, galena, pyrite, and sphalerite.
Workings: This prospect has been explored by a short adit.
Age: Eocene or younger.
Commodities (Major) - Au
Development Status: None
Deposit Model: Epithermal gold vein, Polymetallic vein (Cox and Singer, 1986; model 22c)
