Comments on the geologic information

  • 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.
