Green Rock Energy gearing up for major growth phase


► Recruiting underway for Western Australian and Olympic Dam Projects
► Farm-in discussions with potential Joint Venturers for Olympic Dam
► Design of the work program underway for the Olympic Dam Proof-of-Concept
► Finalising details for drilling program at Olympic Dam
► Application for $7 million grant under the Federal Government Geothermal
Drilling Program


Green Rock Energy Limited is preparing for a major growth phase with the planned drilling in the first half of 2009
at Olympic Dam to complete the Proof-of-Concept and the imminent announcement of the successful tenders for
Western Australian geothermal tenements.

Olympic Dam Geothermal Energy Project : Proof-of-Concept
The Company is designing the work program for the drilling of two deep evaluation wells and associated water
circulation testing at its Olympic Dam Geothermal Energy project following the successful completion of the
hydraulic testing on its Blanche No 1 well undertaken earlier this year. This work is in preparation for the
construction of a series of engineered geothermal systems or reservoirs at Olympic Dam to provide the heat
energy to power a large base load power plant with a capacity in excess of 400 MW of electricity. The two
evaluation wells for the Proof-of-Concept phase will be drilled a few kilometres to the west of Blanche No 1 well,
and approximately 15 kms from BHP Billiton’s mining operation. The Company is currently determining the most
suitable drill rig capable of drilling the deep evaluation wells with an announcement on the successful drilling
company expected in early July, with drilling then scheduled for the first half of 2009.
To reduce the cost of the Proof-of-Concept for the shareholders, the Company is discussing farm-in
arrangements with major power and resource companies and will apply for a $7 million grant under the Federal
Government’s recently announced $50 million Geothermal Drilling Program. Concurrently the Company is
recruiting a Project Manager to oversee and manage the design and implementation of the Proof-of-Concept and
subsequent development.

Western Australia tenements
Green Rock Energy Limited has applied for several geothermal tenements in the Perth Basin, Western Australia.
The Company will be the operator of the tenements which have been applied for jointly with major resource
companies.

Green Rock Energy has been working with Professor Klaus Regenauer-Lieb, Premier’s Research Fellow, The
University of Western Australia and CSIRO Exploration and Mining and his team using multi-scale heat transfer
modelling of the geothermal aquifers in the Perth Basin to identify and target specific site locations for the most
economic geothermal heat sources.

The Company is now recruiting an additional geologist and geophysicist to support the Company’s existing team
and undertake the detailed exploration programs following the announcement of the results of the applications
scheduled for mid July.
