Au
Cubic
Gold, an exceedingly rare mineral locally, was reported from Sterling Hill by Frondel (1972), who noted the original verification by Paul Chorney of the New Jersey Zinc Company in 1940. Gold occurs as bright yellow microscopic flakes, commonly untarnished. One such flake, of exceedingly bright yellow color, was examined by this writer, using energy-dispersive X-ray analysis, and found to have Au >> Ag. Gold has not been verified from Franklin, but small amounts likely occur there unobserved. At Sterling Hill, gold occurs interstitially in chalcocite-rich ore. On casual visual observation, gold may be confused with kittatinnyite and can be distinguished by its sectility. As noted by Frondel (1972), many specimens are labeled fictitiously.
