Location: This occurrence is in a saddle along an east-west trending ridge about 2.5 miles north of the Reindeer River. It is at an elevation of about 650 feet, about 0.6 mile northeast of hill 710, and about 0.5 mile southwest of the center of section 3, T. 26 N., R. 51 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence consists of hematite veinlets in a dacite flow of the Upper Cretaceous or early Tertiary, Yetna River volcanic field (Miller and Bundtzen, 1994; Bundtzen and Miller, 1997; Miller, Bundtzen, and Gray, 2005). The size and orientation of the occurrence are uncertain. One grab sample of mineralization contained 50 parts per billion (ppb) gold and 18 parts per million (ppm) antimony (McGimsey and others, 1988).
Workings: Samples were collected by the U.S. Geological Survey and Alaska Division of Geological and Geophysical Surveys in the 1980s (McGimsey and others, 1988).
Alteration: Deposition of hematite and silicification.
