 The hot springs adjacent to Mount Cayley have made the volcanic field a target for geothermal exploration. At least 16 geothermal sites have been identified in British Columbia, Mount Cayley being one of the six areas most capable for commercial development. Others include Meager Creek and Pebble Creek near Pemberton, Lakelse Hot Springs near Terrace, Mount Edziza on the Tahltan Highland and the Lillooet Fault Zone between Harrison Lake and the community of Lillooet. Temperatures of 50°C (122°F) to more than 100°C (212°F) have been measured in shallow boreholes on the southwestern flank of Mount Cayley. However, its severe terrain makes it challenging to develop a proposed 100 megawatt power station in the area.
