Eagle Creek; Easy Creek Mine, Kougarok District, Nome Borough, Alaska, USA

Location: Eagle Creek, a small east tributary to Iron Creek (SO127), was originally named Easy Creek. The mouth of Eagle Creek is about 1.8 miles downstream from the origin of Iron Creek at the confluence of Canyon and Dome Creeks. This is locality 35 (Easy Creek ) of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Placer mining on lower Eagle Creek took place before 1910. This part of Eagle Creek cuts through a bench of Iron Creek that contains some gold but successful mining was on the active drainage. Bedrock includes marble with many sulfide veinlets and the placer concentrates contained sulfides (Smith, 1909). Bedrock in the area is a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Workings: Small-scale placer mining along the lower part of the creek took place before 1910.
Age: Quaternary; presence of gold-bearing bench deposits indicates two or more cycles of erosion and deposition.

Commodities (Major) - Au
Development Status: Yes; small
Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a).
