Location: This occurrence is on a small ridge on the north side of Death Valley and between the headwater reaches of two unnamed north tributaries to Tubutulik River. It is at approximately 1,500 feet in elevation. This is locality 44 and 45 of Gamble (1988).
Geology: This occurrence is in the eastern-most part of the Bendeleben Mountains in an area of high-grade metamorphic rocks intruded by many small granitic bodies (Till and others, 1986). A grab sample of gossanous schist contained greater than 10,000 ppm bismuth (Miller and Grybeck, 1973). Another grab sample of calc-silicate hornfels, schist, and granitic rock contained 68 ppm Bi and 100 ppm W (Gamble, 1988).
Workings: Exploration activities at this location are not known but are probably minimal.
Age: Cretaceous ?; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age.
Commodities (Major) - Bi; (Minor) - W
