Comments on the geologic information

  • Geologic Description = Numerous small quartz veins and veinlets carrying chalcopyrite and galena in quartzose rocks in contact aureole of granitic intrusive (Mayfield and Grybeck, 1978). Selected specimens from this occurrence were reported by Berg and Cobb (1967, p.105-106) to contain 9.81% Cu and 27.73% Pb, as well as minor amounts of Au and Ag; they also reported tetrahedrite in float.
