The property is underlain by siltstones, sandstones, limestones and minor basic volcanics of probable Lower Paleozoic Lardeau Group. The rocks are affected by low grade regional metamorphism and are part of the lower (inverted) limb of a major F1 regional nappe structure which has been subsequently deformed by F2 recumbent isoclinal folds and later open folds. The latter are related to the Downie Creek pluton which consists of biotite-quartz monzonite.
The sedimentary rocks in contact with the pluton are converted to schists, hornfels and scheelite-bearing skarns. Two distinct mineralized zones are the cave zone consisting of coarse-grained garnet diopside skarn, with abundant disseminated scheelite, and traces of molybdenite, devoid of sulphides, and the slide zone consisting of a quartz sulphide-scheelite breccia zone.
Trace disseminations of chalcopyrite and malachite with pyrite were reported in the southern property area.
