|Location and accuracy||This occurrence is located on a low ridge along the west side of the Chitina River, about 500 feet south of the north boundary of the Valdez B-1 topographic map. It is in the NE1/4 section 26, T. 4 S., R. 6 E., of the Copper River Meridian. This prospect is probably located to within one-quarter mile; it is locality 61 of Winkler and others (1981 [OFR 80-892-B]).|
Geologic descriptionSparse chalcopyrite and molybdenite are disseminated in Jurassic (?) biotite granodiorite (Winkler and others, 1981 [OFR 80-892-B]; Winkler and others, 1981 [OFR 80-892-A]). The pluton is in metamorphic rocks that include mafic metavolcanic rocks of the Paleozoic Skolai Group.
