|Location and accuracy||This prospect is at an elevation of about 300 feet, about 1.2 miles north of the mouth of Pack Creek. The prospect is 0.4 mile southeast of the center of sec. 31, T. 45 S., R. 69 E. It is MAS no. 0021140182 (U.S. Bureau of Land Management, 2002). The location is accurate within 0.2 mile.|
Geologic descriptionThe rocks in the vicinity of this prospect are part of the Triassic Hyd Formation which consists of volcanic rocks, limestone, slate, chert, and conglomerate (Lathram and others, 1965). Little is known about the prospect other than that one or more claims were staked for copper (U.S. Bureau of Land Management, 2002). The deposit may be related to the Copper Chief prospect (SI067) about a mile to the north.
