Location: This occurrence is near the top of hill 680, about 5 miles north of the Reindeer River. The occurrence is near the center of section 32, T. 27 N., R. 52 W., of the Seward Meridian. The location is accurate.
Geology: This occurrence is a zone of intense iron-oxide alteration in sandstone of the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). As exposed in rubble, veins of secondary hematite of uncertain extent and orientation crosscut the sandstone beds. Grab samples of the hematite-rich veins contain up to 150 parts per million arsenic, and trace amounts of antimony, mercury, silver, and gold (McGimsey and others, 1988).
Workings: Samples were collected by the U.S. Geological Survey in 1985 (McGimsey and others, 1988).
Alteration: Secondary hematite and intense iron oxide staining.
Commodities (Major) - As; (Minor) - Ag, Au, Hg, Sb
Development Status: None
Deposit Model: Hematite veins in sandstone.
