The Wishing Well occurrence consists of radioactive tufa associated with cool springs. It is located in the middle of a small group of claims, staked probably around 1954, on the east side of Deer River, 12 kilometres north of the Liard River, 25 kilometres north-northwest of Mount Prudence (Property File - H., S., 1964).

The area is underlain by shale, siltstone and sandstone of the Upper Devonian Besa River Formation, belonging to Ancestral North America (Geological Survey of Canada Open File 673 and Map 1713A).

Quaternary deposits of calcareous tufa have formed around cool springs. The water in the springs is slightly radioactive, possibly from dissolved radon gas, or from minute amounts of radium. At least some of the tufa is also mildly radioactive, possibly due to the deposition of uranium or radium salts (Property File - H., S., 1964). Analyses of similar radioactive tufa from hot springs in the Liard region actually indicate that no uranium or thorium is present, suggesting that the radioactivity is most likely due to small amounts of radium, derived from bedrock (Geological Survey of Canada Economic Geology Report Number 16).
