A number of fine specimens were preserved due largely to the efforts of a contract collector, Mr. Casey Jones. Jones assigned names to the larger vugs such as the Drill Pocket, Lucky Friday Pocket, Sunset Pocket and Quick Pocket. Excellent specimens have made their way into museum and private collections. A number of the best specimens are illustrated in LaBerge, 1997. Chalcocite was found with chalcopyrite, malachite in a deposit on upper east side of Hagerman Hill, SEc.
Chalcocite occurs as small xls.
