Location: This occurrence is at an elevation of about 2,050 feet on a saddle that separates two forks of Moose Creek . The occurrence is about 0.7 mile northwest of hill 2581 and about 0.4 mile east of the center of section 1, T. 30 N., R. 42 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence contains two types of mineralization: 1) an iron-oxide-stained quartz breccia zone in altered tuff of the Beaver Mountains volcanic field; and 2) sheeted quartz veins in beds of altered sandstone in the Beaver Mountains volcanic field (Bundtzen, Laird, and Lockwood, 1988; Miller and Bundtzen, 1988; Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). The size of the occurrence is unknown. Grab samples contained up to 200 parts per billion (ppb) silver, 7,000 ppb mercury, 110 parts per million (ppm) arsenic, and 32 ppm antimony (Bundtzen, Laird, and Lockwood, 1988; McGimsey and others, 1988).
Workings: Surface sampling was conducted by the Alaska Division of Geological and Geophysical Surveys and the U.S. Geological Survey in the 1980s (Bundtzen, Laird, and Lockwood, 1988; McGimsey and others, 1988).
Alteration: Silicification with introduction of chalcedony and development of iron oxides. alteration.
Commodities (Major) - Ag, Hg; (Minor) - As, Sb
Development Status: None
Deposit Model: Polymetallic vein? (Cox and Singer, 1986; model 22c).
