Not enough base metal mineralization exposed to encourage development work (Landes, 1927).
Location: Located on northwestern slope (1,500 ft elevation) of Mount Eklutna, 3,500 ft southeast of Mirror Lake. Accurate within 1,000 ft. Labeled as 'Lead-zinc prospect' by Clark and Bartsch (1967), locality 38 of Cobb (1972), and locality 28 of MacKevett and Holloway (1977).
Geology: Country rock is greenstone and silicified rhyolite of Jurassic to Permian age. A vertical zone about 3 ft wide contains disseminations and small masses of arsenopyrite, pyrite, sphalerite and galena. In addition, a 2 inch wide calcite vein found within a zone of rusty gouge contains disseminated sphalerite, galena, and chalcopyrite (Landes, 1927).
Workings: Surface mapping and sampling.
Age: Jurassic or younger
Commodities (Major) - Pb, Zn; (Minor) - Cu
Development Status: None
Deposit Model: Kuroko massive sulfide ? (Cox and Singer, 1986; model 28a ?)
