Location: East Creek originates near Ipnek Mountain and flows west to Michigan Creek. The junction of East and Michigan Creeks is about 5.2 miles northwest of Ipnek Mountain. The location of the placer occurrence along East Creek is not known and this occurrence is arbitrarily placed about a mile upstream from the mouth of the creek.
Geology: Although Reed (1938) did not visit East Creek, he reports that it drains an area of schist and that very good placer prospects were found along it in the early 1900's.
Workings: Possibly only some prospecting.
Age: Quaternary.

Commodities (Major) - Au
Development Status: None
Deposit Model: Placer Au (Cox and Singer, 1986; model 39a)
