Relative position The Candle-East occurrence is located on a low bluff immediately south of the Sterling Landing-Ophir Road at an elevation of 1,000 feet (304 m) in the SW1/4 sec. 14, T. 32 N., R. 35 W., of the Seward Meridian. The Candle-East occurrence corresponds to prospects #6 and #7 in Bundtzen and Laird (1983). The reporter visited the site in 1977, 1979, and 1997.

Comments on the geologic information

  • Geologic Description = The Candle-East occurrence consists of a densely concentrated zone of ferricrete-tourmaline veins and stockwork in a brecciated hornfels aureole adjacent to the Late Cretaceous, Candle volcanic-plutonic complex (Bundtzen and Laird, 1983). The zone trends northeast and dips steeply to both the southeast and northwest. The mineralization covers a 100 meter by 15 meter area. A trace of chalcopyrite was observed in one hand specimen. Two chip-channel samples taken across the strike of the mineralization contained up to 2.23 grams/tonne silver, 169 ppm copper, 130 ppm lead, and 246 ppm zinc.
  • Age = Unknown; inferred to be Late Cretaceous based on 70 Ma K-Ar age reported for nearby Candle monzonite pluton by Bundtzen and Laird (1983).
  • Age = Chronological age is for nearby Candle monzonite pluton.
