A detailed self-potential (SP) survey was completed at the Cove Fort-Sulphurdale geothermal area during 1995 and 1996. The survey documents a low-amplitude dipolar anomaly within the producing steam field and sharp, negative anomalies which align with mapped structures in the sulfur pit to the south. Three broader SP anomalies, also of relatively low amplitude, were mapped 1 to 2 km west and northwest of the known steam field. One anomaly coincides with the northwestern limit of a very low resistivity (4 ohm-m) area which extends southeast to the steam field, and is open to the west where the other two SP anomalies occur. Electrical resistivity data were modeled to obtain the intrinsic resistivity distribution at various depths, and these are correlated with SP data and structures interpreted from aeromagnetic and gravity data, and geologic mapping. Three potential drilling targets have been identified which could provide new information about the main hot water reservoir.
