Location and accuracy Magnolia Creek is a north tributary to Igloo Creek in the northern Teller B-1 and southern Teller C-1 quadrangles. The Magnolia Creek prospect is located on the east side of upper Magnolia Creek on the west-facing, headwater slopes of a small east tributary. The prospect is between elevations of 750 and 1100 feet on the west side of the north-south ridge between upper Magnolia Creek and Yale Creek to the east. This prospect was identified in 1982. It was not included in the compilations of Cobb and Sainsbury (1972) or Cobb (1975).

Geologic setting

Geologic description

The Magnolia Creek prospect is an area of anomalous gold values in stream sediments and soils. Magnolia Creek marks the approximate boundary between a highly deformed metapelitic schist to the east and a metapelitic/metacarbonate assemblage to the west. Stream silts in the small east tributary to Magnolia Creek contained highly anomalous gold (295 and 1,830 ppb; Hudson and Wyman, 1983). Follow-up soil sampling on the tundra-mantled slopes in the headwaters of this tributary defined a large area of anomalous gold (5 to 125 ppb), some arsenic (to 62 ppm), and some mercury (to 600 ppb). The area of anomalous soils is about 1.4 miles long in a north-south direction and about 0.5 miles wide in an east -west direction; the upslope limits of the anomalous area have not been determined (Hudson and Wyman, 1983). The nature of the mineralization in the metapelitic schist responsible for the anomalous soils and steam silts has not been determined.
