|Location and accuracy||This prospect is in the headwaters of Otter Creek, a west tributary to Tubutulik River on the south side of Death Valley. The mouth of Otter Creek is 4 miles south of Camp Haven. It is about 4.6 miles upstream from the mouthof the creek or 3,000 feet upstream of the dozer cuts (BN087) on the creek. A 20 foot-deep shaft near two decaying log cabins marks the locality (Herreid, 1965). This is locality 17 of Cobb (1972; MF 417; 1975; OFR 75-429).|
Geologic descriptionA caved shaft, estimated to be 20 feet deep, is located next to two decaying log cabins at this prospect. The shaft is in quartz-mica schist which contains less than 1 % sulfides along tiny quartz veins (Herreid, 1965). Grab samples of quartz-rich and quartz-poor schist from the shaft dump contained 0.03 ounces/ton Au (trace Ag) and 0.01 ounces/ton Au (0.27 ounces/ton Ag) respectively. Bedrock in the area is Lower Paleozoic metasedimentary rocks (Herreid, 1965; Till and others, 1986).
