Location: This occurrence is on the northeast bank of the Holokuk River about 1.0 mile northwest of the mouth of Beemguiga Creek. The occurrence is at an elevation of about 380 feet, about 0.3 mile northwest of the center of section 12, T. 15 N., R. 51 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence consists of a zone of quartz stringers adjacent to a swarm of granite-porphyry dikes that intrudes sandstone and shale of the Upper Cretaceous, Kuskokwim Group (Cady and others, 1955; T.K. Bundtzen, unpublished field data, 1999). The largest dike strikes N45E and is about 30 feet wide. One grab sample of a quartz stringer contained 141 parts per billion (ppb) gold, 138 parts per million (ppm) arsenic, 200 ppb silver, 21 ppm antimony, and 118 ppm copper (T.K. Bundtzen, unpublished analytical data, 1999).
Workings: The U.S. Geological Survey sampled the site in 1999.
Alteration: Sericite alteration in dikes.
Commodities (Major) - Au; (Minor) - Ag, As, Cu, Sb
