The Mann Creek showing is located at 666 metres elevation in the Mann Creek gully, about 1.4 kilometres upstream from Highway 5, 11 kilometres south of Clearwater. Mineralization is found within metamorphosed greenstones of the Devonian to Permian Fennell Formation of the Slide Mountain Group. Calcite-epidote veins contain pyrite and minor chalcopyrite; a quartz-carbonate vein carries galena.

The area was staked as the Sunny Creek claims before 1969. Golden Ears Mines Limited conducted a fieldwork program in November 1973 consisting of geological mapping, geochemical soil and rock sampling and linecutting over the X claims. Prospector J.M. Mirko prospected the property as the Billy claim on behalf of J.W. McLeod in 1980.
