Location: Rabbit Creek and Uncle Sam Creek merge to form Pine Creek on the southwest side of Uncle Sam Mountain. The mouth of Pine Creek is on the lagoon adjacent to Norton Sound, 4.5 miles east of Solomon. The location along Rabbit Creek is not closely constrained; possibly located within one mile. This is locality 102 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Prospect holes uncovered creek gravel overlying well-rounded beach gravels and sand. Two types of well-rounded beach wash are reported; these include black graphitic slate gravel and white, vein quartz, pebble gravel. These overlie a thin sand layer on bedrock. Fine gold was found in the sand on bedrock and in the upper part of decomposed schist bedrock suggesting that the gold may have not traveled far from its bedrock source (Smith, 1909). Most of Rabbit Creek is at elevations between 110 and 250 feet and Quaternary sea level fluctuations would probably have affected this area. Bedrock in the headwaters of Rabbit Creek is part of a lower Paleozoic metasedimentary assemblage that includes a distinctive black, very fine-grained, graphitic schist in this area (Till and others, 1986).
Workings: Early prospecting included 4 exploration shafts (30, 45, 20 and 30 feet deep) and one shallow pit (Smith, 1909).
Age: Quaternary.
Commodities (Major) - Au
Development Status: No
Deposit Model: Possibly placer Au-PGE (Cox and Singer, 1986; model 39a), but can also include
