Location: This occurrence is about 0.7 miles east of the summit of Mount Seltat along a ridge that extends eastward from the summit. The location is approximate as the area of mineralization is described as occurring in 'talus piles that drain the north and south sides of the rugged eastern ridge of Mount Seltat.' (Still and others, 1991). It is shown as number 2 on sheet 1 by Still and others (1991).
Geology: Ore minerals are found in talus piles along the north and south sides of a rugged ridge that extends to the east from Mount Seltat. The mineralized talus is probably derived from brown-black manganese-stained bands that crop out between elevations of 4,000 feet and 6,000 feet on the ridge. Gilbert and others (1991) and Still and others (1991) report that float and rubblecrop samples of skarn or massive sulfides contained up to 0.137 ppm gold, 173.1 ppm silver, 4.13% zinc, 8,400 ppm copper, 2.6% lead, and 1,285 ppm tungsten. Cretaceous to Tertiary intrusive rocks mapped to the east by Gilbert and others (1990) suggest a similar age for this mineralization and alteration.
Age: Probably Cretaceous or Tertiary based on the age of intrusive rocks mapped to the east by Gilbert and others (1990).
Alteration: Skarn.

Commodities (Major) - Ag, Cu, Pb, W, Zn; (Minor) - Au
