Location and accuracy The Eastview prospect is at an elevation of about 4,000 feet on the ridge at the head of Hyphen Creek. The prospect is south of Middle Fork Iron Creek and about 0.3 mile southeast of the top of hill 5066, in the NW1/4NE14 sec. 22, T. 26 N., R. 2 E., Seward Meridian. The location is accurate to within 1/4 mile. This is locality 71 of Csejtey and Miller (1978).

Geologic setting

Geologic description

Basalt float at the Eastview prospect contains banded quartz, hematite, pyrite, and chalcopyrite; the chalcopyrite is locally abundant (Capps, 1919 [B 692]). The rocks in the vicinity are Triassic(?) basalt (Schmidt and others, 2002). Samples collected by the U.S. Bureau of Mines contain up to 23,000 parts per million copper and 6 parts per million silver (Fechner, 1986).
