The hot springs associated with Meager and Cayley have made these two volcanoes targets for geothermal explorations. At Mount Cayley, temperatures of to more than have been measured in shallow boreholes on its southwestern flank. Further north, geothermal exploration at the Mount Meager massif has been undertaken by BC Hydro since the late 1970s. Bottom hole temperatures have been calculated at an average of to , with being the highest recorded temperature. This indicates that the area around Meager is a major geothermal site. The geothermal power is expected to run throughout Western Canada and the likelihood of it extending into the western United States is probable.
