Location: Martin and Katz (1912) reported that fine flour gold was present on all gravel bars of the Koktalee (Koktuli) River. For this record, the map site is in the NW¼ of sec. 26, T2S, R40W, SM. It is on a gravel bar on the Koktuli River arbitrarily chosen to represent the general area of occurrences noted by Martin and Katz (1912). Cobb (1972 [MF 375]; 1976 [OF 76-606]) included these occurrences under the name 'Koktalee River'.
Geology: Martin and Katz (1912) reported that fine flour gold was present on all gravel bars of the Koktalee (Koktuli) River. Bedrock geology is poorly known in this drainage. It is probably mostly Mesozoic sedimentary and igneous rocks (Decker and others, 1994).
Age: Holocene. Deposit Model: Placer Au-PGE (Cox and Singer, 1986; model 39a)
