Location and accuracy 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.

Geologic setting

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.
Geologic map unit (-155.801352798409, 62.8543687347971)
Mineral deposit model Polymetallic vein (Cox and Singer, 1986; model 22c).
Mineral deposit model number 22c
Age of mineralization Unknown; inferred to be Late Cretaceous based on 70 Ma K-Ar age reported for nearby Candle monzonite pluton by Bundtzen and Laird (1983).
Alteration of deposit Extensive ferricrete alteration.

Production and reserves

Workings or exploration The occurrence area has been used as road metal for local road construction and is fairly well exposed. 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.
Indication of production None
