Location: This occurrence is at about 1,250 feet elevation on the southeast side of Peak 1408. It is 4.2 miles northwest of Mt. Kachauik and probably located within 0.25 mile. This is locality 69 of Gamble (1988).
Geology: This occurrence is along the north contact of the Kachauik pluton with schistose Ordovician chlorite marble (Till and others, 1986). The plutonic rock at this location is described as a hybrid diorite with abundant biotite (Till and others, 1986). Other parts of the Kachauik pluton to the south are leucocratic, granodiorite to quartz monzonite (Miller and others, 1972). A composite sample of iron-stained intrusive rocks and fluorite-bearing calc-silicate hornfels contained 100 ppm W and 20 ppm Be (Gamble, 1988). The Kachauik pluton is mid-Cretaceous; a K/Ar date for the pluton is 86.1 +/- 3 Ma (Miller and others, 1972).
Workings: No workings or exploration acitivities are known but regional stream sediment geochemistry and airborne radiometric surveys may have been completed in the area.
Age: Mid-Cretaceous; a K/Ar date for the Kachauik pluton is 86.1 +/- 3 Ma (Miller and others, 1972).
Alteration: Calc-silicate minerals are developed in the impure marble country rocks adjacent to the Kachauik pluton. Oxidation of iron-bearing minerals in the intrusive rocks is indicated by iron-oxide staining.
Commodities (Major) - W; (Minor) - Be
Development Status: None
