Abstract: The Warrego Geothermal Project area surrounds the old Warrego Mine located approximately 40 km west of Tennant Creek. There is a distinct geothermal anomaly associated at the Warrego Mine. The anomalously high geothermal gradients were located in the mid 1960s when deep (400m) drill holes were probed by researchers from ANU. These high temperatures were confirmed by subsequent testing in the 1970s and during mining when rock and water temperatures at least twice that normally expected in the area were encountered during mining operations with temperatures more than 600 Degrees C at depths of 600 metres in the mine. While an expensive operating nuisance during mining operations, the exact source of the heat was not located during mining but is thought to be a nearby granite located to the west of the mine and which is interpreted as being the source of a zone of contact metamorphism superimposed on the local mine rocks.
The granitic rocks located to the west of Warrego mine are the most likely cause of the high earth heat flows noted at the Warrego mine. Geophysical analysis of the granitic rocks shows the presence of at least three principal centres aligned approximately north-south. The largest centre is located immediately west of Warrego mine. The other two centres are located at the far north and far south of the granitic mass.
