Location: Small placer gold mine near the mouth of Nigikpalvgururvrak Creek, in the NW 1/4 of sec. 26, T. 27 N., R. 13 E., of the Kateel River Meridian. Locality 7 of Grybeck and Nelson, 1981. Location accurate to within 300 ft.
Geology: Placer gold may be derived from nearby pyritic quartz veins in phyllite of the Hunt Fork Shale (Degenhart and others, 1978). A few tens of ounces of gold per year were being produced for several years in the mid-1970's; production may have continued for some further uncertain period. No record of mining prior to 1970's nor any record of substanital production in recent years.
Workings: Minor gold production using small-scale, non-mechanized methods up to about 1978. Production of gold amounted to a few tens of ounces/year (Degenhart and others, 1978).
