See Eagle Creek Gulch (MD075). The Eagle Creek mine is on land selected or conveyed to Doyon Ltd. For further information, contact Doyon Ltd. at 210 1st Ave., Fairbanks, Alaska, 99701.
Location: The Eagle Creek placer mine is located at an elevation of 500 feet (151 m) in Eagle Creek Basin in Section 29, T. 27 S., R. 21 E., of the Kateel River Meridian. Accuracy is judged to be within a one mile (1.6 km) radius based on location by White and Stevens (1953).
Geology: Geologic descriptions of Eagle Creek placer mine (deposit) are based on descriptions of White and Stevens (1953), and personal communications with Ted Almasy of McGrath (1998). Concentrates were composed of nearly 85 percent ilmenite. Eagle Creek is a second order stream that flows southwesterly towards Crooked Creek. The paystreak mined was approximately 100 feet (30) wide and covered by 16 feet (5m) of overburden. (Ted Almasy, personal communication, 1998.) Age of mineralization is unknown. The average grade of the deposit is unknown.
Workings: Surface workings only.
Production: Jack Nixon first mined the Eagle Creek placer gold deposit in 1918 (Ted Almasy, personal communication, 1998). Prior to World War II mining activities were intermittent and on a small scale. A production estimate is not available.
Commodities (Major) - Ag, Au; (Minor) - Th, U, W
Development Status: Yes; small
