Location: This occurrence is an area of about 12 square miles southeast of the Horn Mountains, centered on VABM Shale. The coordinates are at the center of the area which is at an elevation of about 1,400 feet in the in the SE1/4 sec. 34, T. 19 N., R. 50 W., of the Seward Meridian.
Geology: This occurrence is an area of about 12 square miles defined by geochemical anomalies in stream sediment and panned concentrate samples ( Gray and others, 1994; Theodorakos and others, 1992). The rocks in the area consist mainly of sandstone, siltstone, and shale of the Upper Cretaceous, Kuskokwim Group (Bundtzen and others, 1998). Gray and others (1994) report that two stream sediment samples contained 18 and 12 parts per billion (ppb) gold; heavy mineral concentrates contained up to 1,000 parts per million (ppm) tin, 10,000 ppm barium, 200 ppm lead, and microscopically visible gold, scheelite, and barite. The elevated metal contents may indicate a buried mineralized intrusion or placer deposits in glaciofluvial sediments originating in the the Horn Mountains (Gray and others, 1994; Bundtzen and others, 1998).
Workings: Geochemical sampling.
