Devil Resources Limited (DRL) is a private Australian based energy company exploring for sub-surface Helium, Hydrogen and geothermal resources in Tasmania and the company has two 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 iron rich 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 recently been granted EL5/2024, a H2/He exploration licenses (~4,000 sq km) in NE Tasmania, and SEL10/2023, a 2000 sq km geothermal exploration license exploring for a Hot Sedimentary Aquifer (HSA). This is a hot wet rock geothermal system, different to a Hot Dry Rock (HDR) or Enhanced Geothermal System (EGS)
​
DRL’s founders are Mick Small and Hamish Gordon, with fellow technical director Dr Dave Bennett, all experienced energy professionals.
​
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 Early Cambrian Ultramafics which have a high H2 production potential, plus Granites producing Helium via radioactive decay.
​
The company anticipates grant of the exploration licenses in September 2024.
​
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.
