Slide 4: Exploring for Heat – Paralana Project
Exploring for Heat – Paralana Project 62uWm-3 22uWm-3 Insulator Up to 20 times normal granite: average = 8 times Permian Mt Painter Basement Adelaidean Curnamona Mt Painter Basement Basement Normal basement Early modelling indicated 180oC - 200oC at approximately 4 km
Slide 5: Poontana Basin
Poontana Basin 109oC › Heat flow of 129 mWm-2 › Modeled 180oC-200oC at ~ 4 km (Seismic Line 84 SPG)
Slide 6: Development Model – Heat Exchanger Within Insulator
Development Model – Heat Exchanger Within Insulator › Higher Permeability › Chemically Stable › Lower Frac Challenge? › Adelaidean – bedding / joint surfaces = Cheaper Power!
Slide 7: Paralana Project – Commercial Overview
Paralana Project – Commercial Overview › Commercially viable at all stages. Small off grid market (5-30MWe) (Heathgate) followed by large on grid development (260 MWe+) › Expenditure well leveraged for proof of concept, then potentially fully funded to initial commercial demonstration scale 30MW pla

Scenario Planning vs. Murphy’s Law
Slide 14: Paralana 2 – Drilling
Paralana 2 – Drilling Very Hard Rock Formations – slow ROP 1-3 m/hr Tested several BHA arrangements to optimise ROP
Slide 15: Paralana 2 - Drilling Completed to 4012 M
Paralana 2 - Drilling Completed to 4012 M – 9 Nov 2009 First well designed following low-risk, standard operating methods Steady but slow drilling due to hard formations Conservatively drilled to ensure success to 4012m Wireline and LWD logging completed Well cased and cemented to 3725m Bottom hole
Slide 16: Paralana 2 – Reservoir Characteristics
Paralana 2 – Reservoir Characteristics Inflow zones from 3690m Zr dataing confirms old 1590Ma Reservoir Sequence Contains numerous fractures and faults High pressure geothermal brines intersected 2D Seismic suggests fractured reservoir sequence is regionally extensive
