The Demuth anomaly is located approximately 24 kilometres west- northwest of Summerland. The anomaly was previously included as MINFILE showing 082ENW072.

The area is underlain by granite and granodiorite of the Middle Jurassic Osprey Lake Intrusions.

Stream sediment sampling of drainages in this immediate area yielded values up to 0.093 per cent uranium (Assessment Report 7301). Subsequent soil sampling was not able to identify any area of uranium enrichment. It was concluded that the uranium in the stream sediments was associated with magnetite and sphene, and that the source was an undiscovered bedrock occurrence.
