The Vernon Granite deposit is located 16 kilometres southwest of Vernon, on the east shore of Okanagan Lake.

In this area, Devonian to Triassic sediments of the Harper Ranch Group are intruded by Middle Jurassic granitic rocks of the informally named Terrace Creek batholith. These are intruded by granites and hypabyssal equivalents of the Eocene Coryell Intrusions. Patches of Penticton Group volcanic rocks overlie the older rocks.

The granite has been quarried for industrial use. It is coarse-grained with a fresh light pink tone, containing pink orthoclase feldspar crystals up to 10 millimetres in length. Quartz, plagioclase, biotite and hornblende are also present. Quartz stringers cut the granite and isolated red iron stain patches occur on weathered surfaces.

The quarry is approximately 50 metres long with a face up to 10 metres high. Potential reserves exist to the east. Spacing between joints and fractures is irregular, varying from 0.2 to 2.5 metres, with 60 per cent of recoverable blocks being greater than 50 centimeters square. The stone splits well in all three directions, is practically devoid of knots, takes a high polish and meets all ASTM standards.

From 1912 to the early 1940s about 850 cubic metres were quarried for building purposes and for monument bases by the Vernon Granite and Marble Works. The stone was used in the Vernon courthouse and still looks attractive after 60 years.
