Location: Location plotted is approximate center of localities HP83-HP86 of Meyer and Kurtak (1992, fig. 2), in T33N, R11E; on small southwest flowing tributary draining northwest part of Koiyaktot Mountain, 5.5 mi (8.8 km) northwest of peak 4280; located to within 1 mi (1.6 km).
Geology: Float of quartz-cemented sandstone breccia locally contains massive sphalerite cut by quartz and galena veinlets in area of southwest-dipping Upper Devonian Kanayut Sandstone. Four separate small mineralized areas noted over a 0.5 mi (0.8 km) north-south trend; the largest is a 50 ft (15.2 m) x 300 ft (91.4 m) area of rubble and float of banded color-zoned sphalerite and minor galena veins cross-cutting fine-grained sandstone.
Workings: High-grade samples contain up to 43.9% Zn, 3.27% Pb and 7.15 oz per ton Ag (Meyer and Kurtak, 1992, p. 46-60).
