|Location and accuracy||This occurrence is along the north side of the Richardson Highway about 2 miles southeast of VABM Sponge; it is at an elevation of about 200 feet in the NW1/4 section 30, T. 9 S., R. 4 W., of the Copper River Meridian. This occurence is probably located to within one-quarter mile. It is localities 80 and 81 of Cobb and Matson (1972).|
Geologic descriptionJasper (1967) identified scheelite in heavy mineral concentrate from stream gravels at this locality. Bedrock in the general area is greenschist-facies metaflysch of the Late Cretaceous Valdez Group (Winkler and others, 1981 [OFR 80-892-A]). Gold-bearing quartz veins are widespread through the Valdez Group in the southern Valdez quadrangle (Cobb and Matson, 1972).
