|Location and accuracy||This occurrence is on a south facing bluff overlooking an unnamed east fork of Little Eldorado Creek. It is about 3.5 miles west of VABM 1918/Widgeon and about 0.5 mile north of the center of section 26, T. 25 N., R. 47 W., of the Seward Meridian. The location is accurate.|
Geologic descriptionThis occurrence consists of a zone of iron-staining and sericite alteration in a small granite intrusion that intrudes flysch of the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994; Miller, Bundtzen, and Gray, 2005). One grab sample of weak mineralization contained 50 parts per billion (ppb) gold, 1,800 ppb mercury, and 100 ppb silver (McGimsey and others, 1988).
