It is in the SE1/4 of section 6, T. 12 N., R. 25 E. of the Kateel River Meridian.
Geology: A panned sample from three pans of gravel produced one fine gold particle (Kurtak and others, 1999). The rocks in the area are Cretaceous graywacke and mudstone (Patton and Miller, 1966). No other information is available.
Workings: Surface sampling only.
Age: Quaternary.
