The GAYLE skarn is located approximately 8.5 kilometres from Peachland.

This area, west of Okanagan Lake, saw intensive exploration for copper-molybdenum porphyry deposits in the late 1960s. However, the only recorded work at this location is a 1967 soil geochemical report by J.F. McIntyre, who noted the presence of skarn. The geochemical survey identified a copper anomaly in the vicinity of the showing.

The skarn occurs at the contact between Triassic-Jurassic Nicola Group limestone and marble, and granodiorite of the Early Jurassic Pennask Batholith. The skarn is a medium to coarse-grained garnet-epidote skarn, with garnet predominant. Pyrite and minor amounts of chalcopyrite and molybdenite are found in the skarn member along veins and shears.
