The Sharp Point Hot Springs (Hot Springs Cove) are located on the western side of Sharp Point, eastern side of Refuge Cove, approximately 1 kilometre east of Mate Island.

The area is underlain by high grade metamorphic rocks of the Upper Paleozoic to Lower Mesozoic West Coast Complex. About 1.0 kilometres to the south, a 17-kilometre dyke-like body of granodiorite of the Eocene Catface Intrusions cuts across the metamorphic assemblage (Geological Survey of Canada Map 1537A). A 1913, report states the area to be underlain by medium-grained, somewhat gneissic diorite, composed of andesine feldspar and hornblende with accessory magnetite and apatite. The rock is moderately altered to uralite, chlorite, a little epidote, sericite and kaolinite (Geological Survey of Canada, Summary Report 1913, page 80).

The water, at a temperature of 51 degrees celsius, flows at a rate of 0.4 million litres per day from a 15-centimetre shear zone that strikes 290 degrees. Total salinity is reported at 480 parts per million, sodium chloride content is 350 parts per million (Geological Survey of Canada, Summary Report 1913, page 80). The pH is 8.5.
