Location: This placer prospect area is in the headwaters of an unnamed north tributary to upper Barnum Creek, a north tributary to lower Goodnews River. This unnamed creek and its headwater tributaries drain the southeast flank of Nagotligageivik Mountain. The map site is on the unnamed tributary at an elevation of about 450 feet, at the northeast corner of section 27, T 9 S, R 73 W, of the Seward Meridian.
Geology: This unnamed creek and its headwater tributaries drain the southeast flank of Nagotligageivik Mountain. Fechner (1988) collected four placer samples in the upper part of the drainage. They contained 0.0002 to 0.0010 ounce of gold per cubic yard, and heavy-mineral concentrate from one sample contained Pt and Pd values (Fechner, 1988, p. 60). The gold fineness ranged from 424 to 816. A reconnaissance of the nearby mountain found only barren chert. The gold may be reworked from glacial deposits.
Workings: Reconnaissance stream-sediment and some rock sampling has been done in the headwaters of this drainage (Fechner, 1988).
Age: Holocene.
