3 Slide 3 Green Rock Energy Ltd - Corporate Overview  Australian company, listed on Australian Stock Exchange (code “GRK”)  Market Capitalisation: –A$19.2 million  Options –40 million options –10 cents (April 2008)  Shareholders –2,200 –Top 20 (34%) –Directors (7%)

4 Slide 4 Green Rock Energy Ltd - Business Overview  Developer of commercial geothermal energy projects  Long life resources supplying long life markets  Australian Geothermal Projects (100% interest)  Hungarian Projects (32% interest)

5 Slide 5 Geothermal Energy - Recovering the Earth’s Natural Heat 1.Hot Water –in natural reservoirs –known as “Conventional ” or “Hydrothermal” systems 2. Hot Rocks (EGS) –Hot Dry Rocks

6 Geothermal Resources Slide 6

7 Slide 7 Geothermal Energy - Why geothermal energy? Conventional Geothermal Energy technology is well proven Advantages of Geothermal Energy  Varied uses – electricity, direct heat applications  Renewable energy – access to carbon credits  Domestic source of energy  Base load, long life, power source – high availability >95%  50,000 times energy of known world oil & gas reserves ( US Dept Energy )  Technology driving costs down c.f. fossil fuel prices increasing  Attractive to green/ethical funds Sub-surface Tasks  Both Conventional & EGS - sustainable water circulation flow rate  EGS - fracture stimulation to create a large underground reservoir

8 Slide 8 OD Geothermal Energy Project (100%) Location (2,899 km 2 )

9 Slide 9 OD Geothermal Energy Project Past Activities  Blanche No1 well –Sited 5km from power grid on seismic line –Drilled, cored & logged to 1,935m  In-situ stress analysis (CSIRO)  Temperature measured beneath & around mine  Well production capability (GeothermEx)  Confirmed –Suitable temperatures in granite host –Extensive volume of homogeneous granite –Large potential resource –Likely horizontal flow direction

10 Slide 10 OD Geothermal Energy Project Evaluation & Development Phases  2008 –Mini hydro-fracture of existing slim hole well –Design first of two deep wells –Drill 1st production well –Fracture stimulate 1st well  2009 –Drill 2nd production well –Fracture stimulate 2nd well –Flow test fractured reservoir  2011 –3 to 5 MWe Pilot Power Plant  2013 –+20 MWe modular plants

11 Slide 11 OD Geothermal Energy Project Comparison with other EGS Projects  Project ownership 100% by Green Rock Energy Ltd  Site location Next to power demand and transmission grid  Potential resource Drilled into hot granite and confirmed temperatures  Establish water circulation  Water supplies Adequate water for flow circulation & cooling  Infrastructure Roxby Downs township and services  Connection to electricity grid 10kms from grid  Scaled development Immediate access to market  Experience Conventional & EGS (above & below ground)

12 Slide 12 Patchawarra Project (100% interest) Location (1,483 km 2 )

13 Slide 13 Patchawarra Project Location selection  Patchawarra Trough, Cooper Basin  geological formations prospective for hot geothermal water  Prospective aquifers reach a thickness in excess of 1,200m  at depths in excess of 3,000m  To be evaluated and developed in conjunction with the construction of an electricity distribution network connected to the Cooper Basin

14 Slide 14 Upper Spencer Gulf Project (100% interest) Location (1,938 km 2 )

15 Slide 15 Upper Spencer Gulf Project Location Selection  6 geothermal exploration licenses & two applications  Early stage of evaluation of the granites for EGS  Evaluating direct use of geothermal heat source for a desalination plant

16 Slide 16 Green Rock Energy Ltd - Projects Hungary Geothermal Energy Project (32% interest)

17 Hungary Geothermal Energy Project Why Hungary ?  Good resource potential –high regional heat flow –hot waters intersected in drilling  Extensive database  Supportive legislative regime –attractive feed in tariff pricing €90 /MWh (c.f. Australia: A$50/MWh) –guaranteed access to market  Member of European Union  World Bank backed risk insurance Slide 17

18 Slide 18 Hungary Geothermal Energy Project Joint Venture (32%) Joint Venturers  MOL - a major Hungarian oil & gas company  Enex hf - a major Icelandic geothermal operating & consulting company  Green Rock Energy Limited Scope  Testing of existing hydrocarbon wells or new wells  Generate a pipeline of geothermal projects  >100 MW electricity + direct heat capacity 1 st Site drilled  Suspended (usable for direct heat) Currently selecting 2 nd & 3 rd sites

19 Slide 19 Summary  Commercially driven company  A renewable energy that provides continuous energy  Evaluation and development approach minimizes risk  Ability to develop projects in stages  Both Conventional & EGS geothermal projects  In a market that will only get more focus  International geothermal experience  New incentives announced by governments
