Location: The location of the prospects is a very general one. The coordinates are arbitrarily located at the confluence of the two upper forks of Sinona Creek about 1.5 miles south-southwest of Sinona Lake. The only guide to the location is the statement of Mendenhall and Schrader (1903, p. 49) that 'some further locations have been made in the region between the Gakona and the Chistochina on Excelsior Creek and in the headwaters of the Shnu.' The Shnu is now named Sinona Creek.
Geology: There was some prospecting and possibly minor production of placer gold in the area prior to 1903 (Mendenhall and Schrader, 1903). Sinona Creek has a very low gradient and flows mostly through unconsolidated material. Its headwater tributaries originate the Chistochina gold district of the Mt. Hayes quadrangle and small amounts of flour gold could have washed into Sinona Creek and been concentrated in river bar deposits along the river.
Workings: Probably shallow placer workings prior to 1903 that have long since destroyed by erosion.
Age: Holocene placer.
Commodities (Major) - Au
Development Status: Undetermined.
