Location: This occurrences is about 2.8 miles southwest of Turn Mountain along a logging road. It is about 0.5 mile north of the center of section 12, T. 56 S., R. 72 E.
Geology: This occurrences was discovered by Still and others (2002). A lens of massive barite about 2 feet thick and 6 feet long is exposed in soil above a logging road. The barite contains scattered galena and sphalerite. A select sample contained 13.1 parts per million silver, 1.02 percent lead, 2.0 percent zinc, and 48.37 percent barium. The rocks in the area are mainly argillite of the Hyd Group of Triassic age (Karl and others, 1999).
Workings: None; the only work has been surface sampling by government geologists.
Age: Unclear but associated with rocks of Triassic age.
Commodities (Major) - Ba, Pb, Zn
Development Status: None
Deposit Model: Volcanogenic massive sulfide deposit? (Cox and Singer, 1986, model 28a).
