|Location and accuracy||C.C. Hawley and Associates, Inc. (1978, Fig. 4.2-B(3)) locate this prospect at the confluence of Gold Creek and Cache Creek in the northeast quarter of Section 15, T. 28 N., R. 9 W., of the Seward Meridian. Unpatented claims extend about 1 mile upstream from the confluence.|
At the confluence of Gold Creek and Cache Creek gold occurs in Pleistocene stream placers that range from 2 to 6 feet thick and have a pay streak 20 feet wide. The headwaters of Gold Creek are underlain by Mesozoic slate (KJs) and the lower courses are underlain by Tertiary continental deposits of the Kenai Group (Reed and Nelson, 1980). Gold is found on the bedrock surface and inside crevices in the slate at the Tertiary-Mesozoic unconformity (Capps, 1913). The fineness of the gold from Gold Creek is 857.5 (Clark and Hawley, 1968).Also see Cache Creek (TL029).
