Location: Location plotted is locality HP90 of Meyer and Kurtak (1992, fig. 2), in T32N, R12E; just north of divide in southeastern part of Koiyaktot Mountain on minor northeast draining tributary of Nigu River, about 1 mi (1.6 km) north-northwest of Peak 4280; located to within 2000 ft (610 m).
Geology: This occurrence is a north-south zone of quartz veinlets and quartz-cemented sandstone breccia float and rubble containing locally massive galena and sphalerite; and is located in an incompletely mapped area of folded and thrusted sandstone, siltstone, shale, and conglomerate of the Upper Devonian to Lower Mississippian Endicott Group.
Workings: A high grade sample contains up to 39.9% Pb, 23.94% Zn, 875 ppm Cu and 53.6 oz per ton Ag; stream sediment samples collected in this area by the U.S. Bureau of Mines are also anomalous in these elements (Meyer and Kurtak, 1992, p. 46-61).
Commodities (Major) - Pb, Zn; (Minor) - Ag
Development Status: No
Deposit Model: Lode; sediment-hosted vein and breccia vein Pb-Zn-Ag.
