Exploring Tasmania for Helium, geothermal & Nat H2
Devil Resources has licensed 12,000 sq km onshore Tasmania over a highly prospective area. The company is using cutting edge technology to search for these critical resources.
NE Tasmania has some of the highest heat flow values in Australia. This is due to crustal thinning and being under laid by granite rocks which produce geothermal heat by radiolysis. Eastern Tasmania has all the hallmarks of hosting a ‘blind’ hot and wet rock geothermal system. The type of geothermal system in Tasmania that DRL is exploring for is a likely to be a depth of 2-4km below ground level.
This heat has the potential to be tapped to generate base load electricity of up to several hundred MW.

Australia Heat Flow
•Heat is generated by radioactive decay of Uranium, Potassium and Thorium within granitic rocks + heat transfer from the shallower mantle
• Cooper Basin and North-Eastern Tasmania have crustal thickness <30km. A Thin Crust
•NE Tasmania has some of the highest recorded heat flow values in Australia
NE Tasmania Granites dominate the geology of the area
• Granites (pink units) outcropping at surface and underlay the sub surface
•A series of shallow heat flow borehole drilled by a previous explorer in 2009-09 established the area has high heat flow values (marked red wells with heat flow values) which are double average continental values suggesting the presence of blind geothermal system in NE Tasmania
