These prospect are in the Karta River Wilderness Area, which is closed to exploration and mining.
Location: As plotted on a small map by Wright and Wright (1908), the Juneau claims are about halfway between Granite Mountain and Salmon Lake; by implication, the Go-by claims are nearby. For this record, the location is about 1.2 mile north-northwest of Granite Mountain and about 0.5 mile southwest of the center of section 8, T. 73 S., R. 84 E. The claims are probably within one-half mile of this location.
Geology: The rocks in the vicinity of these prospects are part of a large granodiorite-quartz diorite stock (Sainsbury, 1961; Eberlein and others, 1983; Brew, 1996). Early workers considered the stock to be Mesozoic or Cretaceous, but recent radiometric dating indicates that it is Devonian (S.M. Karl, oral communication, 2003). The only published description of the deposits on the Juneau and Go-by claims indicates that they are similar to the other gold-quartz veins on Granite Mountain (Wright and Wright, 1908). There is no information about any workings.
Workings: There is no information about any workings on these prospects.
Age: Unknown, other than that the veins are in Devonian granitic rocks.
Commodities (Major) - Au, Cu, Pb
Development Status: None
Deposit Model: Gold-quartz vein (Cox and Singer, 1986; model 36a).
