The Ruby Gold showing is located 10 kilometres west of Vernon, on the east side of Okanagan Lake.
In this area, west of the Okanagan Valley fault zone, volcanic and sedimentary rocks of the Devonian to Triassic Harper Ranch Group are unconformably overlain by Upper Triassic to Lower Jurassic Nicola Group sedimentary and volcanic rocks. These units are intruded by Middle Jurassic granitic rocks informally named the Terrace Creek batholith. Patches of Eocene Penticton Group volcanic rocks overlie the older rocks.
A quartz vein in mylonitic granite hosts gold mineralization. The 3 to 3.7 metre thick quartz vein carries pyrite and free gold and has been traced for about 60 metres. At the bottom of the 9.1-metre shaft the vein breaks up into stringers.
A shaft was driven on the claim in 1897. The Ruby Gold claim was Crown-granted in 1904.
