Identification information

Deposit ID 10307338
Record type Site
Current site name Discovery Creek

Geographic coordinates

Geographic coordinates: -149.77334, 67.5797 (WGS84)
Relative position Discovery Creek, which is not named on the topographic map, drains the south flank of Sukakpak Mountain. It is about 1 1/2 miles long and heads in the area of the Sukakpak Sb-Au vein prospect (CH076). The point of reference is near the mouth of the creek (sec. 22, T. 32 N., R. 10 W., of the Fairbanks Meridian), but the site of any placer mining on the creek is not known. The location is accurate within a 1/2-mile radius.

Comments on the geologic information

  • Geologic Description = Discovery Creek drains the Sukakpak Sb-Au vein occurrence (CH076), and the creek gravels contain clasts of stibnite-quartz vein material (Dillon, 1982). Although there is evidence of early workings on the creek (Dillon, 1982), there are no published descriptions of the deposit. The presence of gold in the creek is substantiated by reports of gold recovered with a suction dredge in 1982 (Dillon, 1982).
  • Age = Quaternary.
