Slide 4: Petratherm's Commercial Strategy
Petratherm’s Commercial Strategy The 5 Hot Rock Cost Pillars *Temperature * Flow Rate * Depth (Drill Cost) ¢« Location ¢ Plant Shallow Hot Rocks Close to Market!
Slide 5: South Australia
South Australis Exceptional target for Geothermal Energy 80% higher heat flow than typical Proterozic crust Heat due to : * Thermally Anomalous Granite (TAG) + Radiogenic Iron Oxide (RIO)
Slide 6: Finding Hot Rocks
Finding Hot Rocks In Australia only 7% of the continent has sufficient well hole data Forward modelling of Geothermal Resource potential based on constrained geological models Prediction of geothermal gradients Target depths Heat outputs
Slide 7: Mt Painter
Mt Painter Project Areas Evidence for Thermal Anomalism *Hot Springs «Fossil Hydrothermal Breccias «Elevated groundwater temperatures *High Heat flow recorded “Arkaroola, village Callabonna Project Interpreted Outlines of Callabonna Granite Mt Painter Inlier (Outcropping Thermaily. Anomalous Granite
