Location: The area of this site was examined by Clark and others (1970 [OF 417]) and by D.J. Grybeck (unpublished field notes, 1980). In May 1980, red flagging marked locations along the creek where private industry had taken samples and one or more claims were probably staked. The site is about 0.5 mile southwest of the center of section 18, T. 75 S., R. 83 E.
Geology: Clark and others (1970 [OF 417]) noted greenschist with pyrite and chalcopyrite near this site, and Grybeck (unpublished field notes and analyses, 1980) noted quartz-sericite schist and subordinate quartz-chlorite schist in the banks of the creek. The rocks are part of the Wales Group of Cambrian and older age (Brew, 1996). Grybeck did not observe base-metal mineralization, but up to about 5 percent pyrite is widely disseminated in the schist. Much red flagging was present in 1980, and the area has probably been claimed or sampled by private industry. Grybeck collected several random samples of the pyritiferous schist; none contained significant metal values.
Workings: None noted other than flagging from claim staking or sampling.
Age: A metalliferous horizon in Cambrian or older felsic schist.
Commodities (Major) - Cu
Development Status: None
