Location: The coordinates are for the approximate center of the lowermost of two placered areas on the creek. Both areas are about 1,500 to 2,000 ft long. Palmer Creek is a tributary to the Middle Fork of the Chena River.
Geology: Numerous quartz and calcite veinlets that cut the quartzitic and phyllitic country rock have been considered the source of gold by some workers (Menzie and others, 1983, p. 50). During mining operations in 1941 most of the concentrates consisted of scheelite (Joesting, 1942, p. 41). No granitic rocks are known in the drainage area and there are no igneous rocks in the stream gravels, so the scheelite probably occurs in some of the numerous quartz stringers in the schist country rock (Joesting, 1942, p. 41).
Workings: Surface mining in 1937 to 1941 or later (Lampright, 1996, p. 73).
Production: Mining has been reported (see workings/exploration); however, amount of production is unknown.
Commodities (Major) - Au; (Minor) - W
Development Status: Yes; small
Deposit Model: Placer gold deposit (Cox and Singer, 1986; model 39a)
