Location and accuracy This site represents a large claim block noted on U.S. Bureau of Mines maps in 1973. It is located west of the Douglas River and centered in sec. 21, T. 15 S., R. 28 W. (MacKevett and Holloway, 1977, locality 4; Church and others, 1992, sheet 1, locality 10).

Geologic setting

Geologic description

No significant mineralization was found during a brief reconnaissance of the area (Church and others, 1992); however, some quartz veining and disseminated pyrite has been noted in the general area (Church and others, 1994). Some potential for polymetallic veins exists. Jurassic and Cretaceous sedimentary rocks underlie the claims. A small Tertiary intrusive has been tentatively mapped approximately 2 miles east of the site location as plotted.
