No additional information is available since Becker's 1898 description.
Location: This site is located on the west side of Uyak Bay approximately 2 miles northwest of triangulation station Bush and 2 1/2 miles southeast of Larsen Bay ( Martin 1913, locality 11; Berg and Cobb, 1967, figure 15, locality 10; Cobb, 1972, MF 460, locality 1; McGee, 1972, locality 10; MacKevett and Holloway, 1977, locality 1). Site location is accurate to within 1/2 mile.
Geology: This occurrence consists of a 20-inch-thick quartz vein which strikes northwest and dips southwest, approximately parallel to the Bear (KD003) and Dan (KD004) veins. It crops out northeast of the Dan and cuts Cretaceous metasedimentary rock. The vein carries arsenopyrite, pyrite, galena, and gold. Acidic dikes occur in the vicinity.
Age: Cretaceous or younger

Commodities (Major) - Au?, Pb
Development Status: None
Deposit Model: Chugach-type low-sulfide gold-quartz vein (Bliss, 1992; model 36a.1), turbidite
