Devil Resources Limited (DRL) is a private Australian based  energy company exploring for sub-surface He, H2 and geothermal resources in Tasmania and the company has applied for several exploration licenses on the island. Onshore Tasmania has excellent potential to host both geothermal  and sub-surface Helium and Hydrogen resources. Much of Tasmania is also underlaid by thick sequences of thrusted Ultramafic rocks which also have a good potential for CO2 sequestration.

​

DRL is building an exploration portfolio consisting of both geothermal and H2 & He prospects.

​

DRL has one 4,000 sq km H2/He exploration license (EL5/2024) in NE Tasmania, and a 2,000 sq km geothermal exploration license (SEL10/2023), where the company is exploring for a Hot Sedimentary  Aquifer (HSA) system.  This is a hot wet rock geothermal system, different to a Hot Dry Rock (HDR) or Enhanced Geothermal System (EGS)

​

Within Tasmania, there are several exploration wells, of which two 1990’s ones sampled Natural H2 and Helium in the subsurface (He-5% and H2 6.8% in Shittim-1 mud gas samples). Much of Tasmania is underlaid by iron rich Ultramafic rocks which have the potential to naturally produce H2, plus Granite rocks that produce Helium via radioactive decay.

​​

Geothermal exploration stalled in Australia following the collapse of Geodynamics in 2013 which had taken over KUTh Energy, which had defined an prospective hot-wet geothermal province in NE Tasmania related to Devonian Granites. Geothermal Exploration is currently undergoing as renaissance in Australia, due to advances in drilling technology and geothermal energy generation.
