This prospect is on land that has been conveyed to the Sealaska Corporation, who hold the surface and subsurface rights, or the land is under application for transfer to them.
Location: This prospect is at an elevation of about 2,200 feet, just above timberline. It is about 1.3 mile northeast of the abandoned town of Sulzer and about 0.4 mile south-southeast of the center of section 2, T. 76 S., R. 84 E.
Geology: This prospect was first described by Chapin (1918) but apparently has had little attention since. It consists of several small but prominent prospect pits in massive marble of the Wales Group of Late Proterozoic and Cambrian age (D.J. Grybeck, unpublished field notes and analyses, 1984). The dumps contain abundant material with nearly massive sphalerite and galena, and bright-orange gossan. There is minor copper staining and considerable oxidization of the sulfides to secondary lead and zinc minerals. The prospect pits extend for a length of about 300 feet over a vertical range of about 100 feet. Selected sulfide-rich samples contained 20-700 parts per million (ppm) silver, 2,000 to more than 5,000 ppm barium, 500-10,000 ppm copper, and 150-1,500 ppm antimony, as well as major lead and zinc that reflect the galena and sphalerite. The ore minerals are probably a replacement deposit in marble.
Workings: Several prospect pits over a length of about 300 feet.
Age: Unknown, other than that the deposit is in Cambrian or older marble.
Commodities (Major) - Ag, Cu, Pb, Zn; (Minor) - Ba, Sb
Development Status: None
Deposit Model: Ag-Pb-Zn replacement in marble.
