The Sealaska Corporation holds the subsurface rights to the land in the vicinity of this old prospect.
Location: The only published location for this old prospect is a small-scale map and the description by Brooks (1902). He places it about a half mile north of the shore of Polk Inlet at an elevation of about 300 feet. There is a small island on his map in section 25, T. 74 S., R. 85 E. that can be identified on the modern 1:63,360-scale topographic map. The prospect is north of the island, probably within 1/4 mile of the center of the W1/2 section 24, T. 74 S., R. 85 E.
Geology: The only description of this prospect is by Brooks (1902). The rocks in the vicinity include black, carbonaceous, pyritiferous slate that strikes N60W and dips 50NE. The rocks are part of the Descon Formation of Silurian and Ordovician age (Eberlein and others, 1983; Brew, 1996). A small cut exposes a (quartz?) vein up to 4 inches thick in crumpled slate. The vein contains pyrite and less than $1 per ton in gold (at $20.67 per ounce).
Workings: Only a small cut.
Age: Unknown, other than that the vein is in Silurian or Ordovician slate.
Alteration: Slate is crumpled near the vein.

Commodities (Major) - Au
Deposit Model: Quartz(?) vein with low gold values.
