Comments on the geologic information

  • Geologic Description = Sulfides occur as disseminated grains, fracture fillings, and in boxwork quartz in black chert and siliceous shale of Mississippian to Lower Pennsylvanian(?) Kuna Formation of Lisburne Group; felsic to intermediate(?) volcanic rocks are interbedded in the sedimentary section. The sulfides are at the west end of a west-northwest-trending zone of sporadic occurrences that extends about 1.25 mi (2 km) parallel to the strike of bedding and complex structural imbrication. Sulfides probably syngenetic.
  • Age = K-Ar ages of 319+10 and 330+17 Ma were obtained from biotite from a volcanic interbed within the mineralized belt; a Pb-isotope model age of 200 Ma was obtained from galena.
