The Wilson Creek breccia molybdenum occurrence is located 3 kilometres northeast of Rosebery, on the east side of Wilson Creek, east of Slocan Lake.

Traces of molybdenite mineralization are associated with minor quartz-pyrrhotite-pyrite veinlets in hornfels and minor quartz-pyrrhotite-sphalerite-galena veinlets in intrusive breccia (Assessment Report 7848). The highest molybdenum assay in a drillhole (Assessment Report 7848) into the breccia was 8 parts per million. The intrusive breccia is light grey to pale green in colour and contains fragments of purple and bleached hornfels, limestone, quartz monzonite and bull quartz in a calcareous, comminuted rock matrix. The breccia is related to the Rosebery stock which is composed of granite and quartz monzonite (GSC Open File 432). The Rosebery stock intrudes quartzites, argillites and limestones of the Triassic Slocan Group.

The earliest recorded work was "development work" by "hand steel" presumably on silver-lead veins in 1942 (Minister of Mines Annual Report 1942). In 1970, the ground was staked by Peter Leontowicz and optioned by United Bata Resources Limited (later Pan Ocean Oil Limited), who in 1970 (Assessment Report 2944) undertook reconnaissance soil sampling (875 samples analysed for molybdenum and copper). In 1979, Amax Potash Limited optioned the property and undertook a program of geological mapping and collected 369 soil and stream sediment samples which were analysed for 11 elements including molybdenum (Assessment Report 7514). They also completed a 203 metre diamond-drill hole (Assessment Report 7848).
