Identification information

Deposit ID 10308541
Record type Site
Current site name Willow Creek

Geographic coordinates

Geographic coordinates: -148.92332, 67.63972 (WGS84)
Relative position The reference point is the site of a reported zinc occurrence near a headwater tributary of Willow Creek (SW1/4 sec. 33, T. 33 N., R. 6 W., of the Fairbanks Meridian) (Brosgi and Reiser, 1964). Willow Creek is a tributary of Robert Creek and is located approximately 7 to 8 miles northeast of the north end of Twin Lakes. The location is accurate within a 1/2-mile radius.

Comments on the geologic information

  • Geologic Description = Anomalous zinc values were obtained by X-ray analysis of a rock sample collected in an area mapped as Devonian(?) albite-chlorite-mica schist near the contact with calcareous schist and marble (Brosgi and Reiser, 1964). Two rock samples collected by Brosgi and Reiser (1972), which appear to be from the same location as the zinc-bearing sample, contained 5.6 ppm Au in one sample and 0.8 to 1.0 ppm Au in the other.
