Characterization of Ketchem Dome Tin Prospect, East-Central Alaska.

PB88229869

Publication Date	1987
Personal Author	Dahlin, D. C.; Brown, L. L.; Warner, J. D.
Page Count	16
Abstract	The Bureau of Mines investigated the Ketchem Dome tin prospect in east-central Alaska to evaluate the tin resource. The studies included field investigations, mineralogical characterization, and concentration of the tin-bearing minerals. The tin mineralization consists of cassiterite (SnO2), which occurs as grains disseminated in a greisen (quartz-mica) matrix. A bulk sample from the largest and best-developed greisen vein exposed at Ketchem Dome contained 0.51 pct Sn.
