The Gladys C-Cadet occurrence area is underlain by a complex northwest trending sequence of Upper Triassic Quatsino Formation recrystallized limestone and Karmutsen Formation amygdaloidal basalt, both of the Vancouver Group. Several small diorite bodies are evident with mafic diorite dykes and diorite dykes. A teardrop- shaped diorite intrusive occurs on the adjoining Volunteer claim (092F 268) to the northwest. The stratigraphy is strongly sheared in a north-northwest direction and is often faulted in the same direction. Intrusive bodies are commonly emplaced along these faults.

A prominent fault on the Gladys C claim (Lot 135) forms a contact between basalt and limestone. Mineralization is localized in small patchy magnetite-garnet-pyroxene skarns developed in and near the fault. The magnetite skarns are variably mineralized with sphalerite, some chalcopyrite and to a lesser extent, galena and pyrite. A rock sample from a garnet-pyroxene skarn with chalcopyrite assayed 6.31 grams per tonne gold (Assessment Report 18672). Occasional chalcopyrite is also found in quartz stringers in basalt.

Three hundred and fifty metres west of the Gladys C claim, on the Cadet claim (Lot 138), garnet-pyroxene skarn encloses a magnetite-garnet core developed near a diorite intrusive. Rock samples of a magnetite-garnet skarn assayed 1.58 grams per tonne gold and samples from a garnet-pyroxene skarn with chalcopyrite assayed 8.64 grams per tonne gold (Assessment Report 18672).
