|Location and accuracy||This lode occurrence is exposed in a placer cut on Prince Creek, at an elevation of about 400 feet. It is near the center of the south boundary of section 12, T. 26 N., R. 47 W., of the Seward Meridian. The location is accurate.|
Geologic descriptionThis occurrence consists of two quartz-sulfide veinlets in and adjacent to a 6-foot-thick monzonite dike that intrudes hornfels derived from the Upper Cretaceous, Kuskokwim Group (Miller and Bundtzen, 1994). The two veinlets average about 1 inch thick, strike N20E and dip 75SE. Their length is unknown as exposures were limited to the placer cut. Cinnabar and scheelite were noted in one vein (T.K. Bundtzen, unpublished field data, 1984). One grab sample contained 3,400 parts per billion (ppb) gold, 10.0 parts per million (ppm) silver, 1,380 ppm tungsten, 78 ppm bismuth, and 820 ppb mercury (McGimsey and others, 1988; Bundtzen and others, 1992).
