Location: Occurrences of placer gold are on McCallie Creek, an east-flowing tributary of Ohio Creek. The occurrences extend from the mouth of McCallie Creek upstream to the map site, which is in the Se1/4 of sec. 9, T. 21 S., R. 12 W., of the Fairbanks Meridian. This is location E-32 of Balen (1990: OFR 34-90) and is accurate to within 1 mile.
Geology: McCallie Creek hosts several placer gold occurrences. Its drainage area includes Upper Triassic limestone and basalt, in thrust contact with Lower Jurassic and Upper Triassic sandstone, siltstone, argillite, and conglomerate (Wilson and others, 1998). In places, these units are cut by several generations of veins related to Upper Cretaceous or Lower Tertiary plutons. The placer gold probably was derived from the erosion of such veins.
