Commodities (Major) - Hg; (Minor) - Sb
Development Status: None
Deposit Model: Silica-carbonate mercury (Cox and Singer, 1986; model 27c).

Location: The Ammiline prospect is on a west-facing slope of Parks Creek, about 0.6 mile north-northeast of the mouth of Parks Creek. It is at an elevation of about 430 feet in the SE1/4 sec. 24, T. 20 N., R. 45 W., of the Seward Meridian. The prospect is locality 11 of Miller and others (1989).
Geology: At the Ammiline prospect, cinnabar and minor stibnite in a gangue of fine-grained silica occurs along fractures in an albite rhyolite or granite porphyry dike that intrudes shale and sandstone of the Upper Cretaceous, Kuskokwim Group (Cady and others, 1955; Sainsbury and MacKevett, 1965). The Ammiline prospect is geologically similar to the Fairview prospect (SM019). No other information is available.

Age: Undated; the nearby Fairview prospect (ARDF SM019) has a 40Ar/39Ar age of 72.6 Ma (Gray, Gent, and others, 1997).

Alteration: Albitization of the rhyolite host rock.
