Identification information

Deposit ID 10307878
Record type Site
Current site name Ellie's Gold

Geographic coordinates

Geographic coordinates: -153.46381, 62.10048 (WGS84)
Relative position Ellie's Gold occurrence is in a second order stream that flows westerly about 8 kilometers to Post River. It is at an elevation of 3,900 feet (1,189 m) in the NE1/4 sec. 10, T. 23 N., R. 23 W., of the Seward Meridian. The location was determined from the field map plots of E.E. Harris and corresponds to map number 30 in Bundtzen, Harris, and Gilbert (1997).

Comments on the geologic information

  • Geologic Description = The Ellie's Gold occurrence is a concentration of placer gold in a second order stream in the Eocene, Terra Cotta Volcanic field. Abundant black sands - including magnetite - were identified in the panned concentrate collected in the field. Bedrock is shallow and the stream more or less flows on bedrock. Stream gradient is about 200 meters/kilometer; i.e., it is steep. The gold appears as several flat, subangular, pin-sized grains in a black-sand-rich concentrate. The pan concentrate also contained 360 ppm chromium, 220 ppm zinc, and 19.4 percent iron (Bundtzen, Harris, and Gilbert, 1997).
