Geologic setting

Geologic description

Important placer gold deposits were developed on Patterson Creek (BN072) and on Candle Creek (BN074), above and below the mouth of Patterson Creek. Reconnaissance soil samples in the tundra-covered north headwaters of Patterson Creek (elevation 600 to 700 feet) contain anomalous arsenic and one sample contains 20 ppb gold (Hudson and Wyman, 1983). The gold-bearing sample contained 200 ppm As and two other samples from this area contained 115 ppm and greater than 1,000 ppm As. Bedrock is extensively covered by tundra but what is exposed in the area is part of a Lower Paleozoic metasedimentary assemblage (Till and others, 1986). A small granitic stock is exposed on the ridge south of upper Candle Creek (Till and others, 1986) and Sandvik (1956) notes that granitic rocks have been identified in the headwaters of Jump Creek and Minehaha Creek. Intermediate to felsic dikes and sills crosscutting metamorphic rocks have been exposed in placer workings along Candle Creek (BN074).

Mineral deposit model Quartz-arsenopyrite veins in metasedimentary rocks?
Age of mineralization Cretaceous ?; Epigenetic mineralization in metamorphic rocks of Seward Peninsula is primarily of Cretaceous age. Some lode gold deposits on southern Seward Peninsula are mid-Cretaceous in age (see Midnight Mountain, BN047).

Production and reserves

Workings or exploration There are no workings at this location. Only reconnaissance soil sampling has taken place here. Altar Resources (P. O. Box 42831, Tucson, AZ 85733) maintains an active claim block (Wild Bunch claims) covering the uplands to the north and south of Patterson Creek (Altar Resources, 1999).
Indication of production None
