Location: The Gold Dome prospect is on the east side of Harris Dome, 5 miles east of the Nome-Taylor road. The active claims here straddle the divide between Little Harris Creek and Harris Creek which is at an elevation of about 1,175 feet.
Geology: Altar Resources (P. O. Box 42831, Tuscon, AZ 85733) maintains a small claim block on a faulted contact between marble and schist. Stream sediment samples in the area contain up to 390 ppb gold and six soil samples from the divide area between Litle Harris Creek and Harris Creek contain between 10 and 155 ppb gold (Altar Resources, 1999). Metasedimentary rocks in this area are Paleozoic in age (Till and others, 1986).
Workings: Some geologic mapping, soil sampling, and stream sediment sampling has been completed.
Age: Unknown but possibly Cretaceous; if gold-bearing lode structures are present here they may be similar in age to some lode gold deposits of southern Seward Peninsula. The southern Seward Peninsula lode gold deposits formed as a result of mid-Cretaceous metamorphism (Apodoca, 1994; Ford, 1993, Ford and Snee, 1996; Goldfarb and others, 1997) that accompanied regional extension (Miller and Hudson, 1991) and crustal melting (Hudson, 1994). This higher temperature metamorphism was superimposed on high pressure/low temperature metamorphic rocks of the region.
Alteration: Iron oxide staining and quartz veining have been locally observed.
