See also Midas Creek (WI057).
Location: Sixtymile Creek is a large, west-flowing tributary to John River. Fool Creek is not named on the Wiseman B-5 topographic map. But according to Maddren (1913), Fool Creek starts at the junction of Sixtymile and Midas Creeks (although Maddren's map labels the Sixtymile Creek as the Fiftymile Creek ), and enters the John River at the mouth of Crevice Creek. The locations of the placer prospects along 'Fool Creek' are unknown. These prospects are arbitrarily located on Sixtymile (Fool) Creek about 0.9 mile west of the mouth of Rock Creek.
Geology: Maddren (1913) reported good prospects on 'Fool Creek' and its tributaries, and Wimmler (1922) reported coarse gold along benches of Sixtymile Creek. (which is probably another name for Fool Creek). According to Kurtak and others (2002), 83 ounces of gold have been recovered from Sixtymile Creek. The rocks in the area consist mostly of Devonian, Skajit Limestone, with subordinate Middle or Upper Devonian(?) chloritic and carbonate rocks and Proterozoic(?) granite gneiss (Dillon and others, 1986).
Workings: Some prospecting and mining.
Age: Quaternary.
Production: Kurtak and others (2002) report that 83 ounces of gold of gold reported to have been recovered from Sixtymile Creek.
