NOTE: The location of the Silver Star prospect is uncertain. It may be on land that has been conveyed to the Sealaska Corporation, or is under application for transfer to them.
Location: The location of the Silver Star prospect is uncertain. For this record, the site is about 1.4 miles west-northwest of the head of Windy Cove, in the NW1/4 section 16, T. 79 S., R. 82 E. However, Maas and others (1991) could not find the prospect, and suggest that it may be farther to the west, possibly a mile or more away.
Geology: As described by Chapin (1916), the deposit at the Silver Star prospect is in limestone and consists of two parallel veins less than 2.5 feet thick. The veins contain sphalerite, chalcopyrite, galena, and 'notable' gold and silver. The workings consist of an adit with two drifts. There is no more recent description of the deposit and it could not be located by Maas and others (1991) or by Hedderly-Smith (1999 [Inventory]). The host rock probably is Heceta Limestone of Silurian age (Eberlein and others, 1983; Brew, 1996).
Workings: The workings consist of an adit with two drifts that date to before 1918.
Age: Probably Silurian or younger.
