$7 Million Geothermal Drilling Funding for Paralana

The Company is pleased to advise that the Federal Minister for Resources, Energy and Tourism, the Honourable Martin Ferguson, announced today that, subject to successful offer negotiations, $7 Million under Round One of the Federal Government’s $50 Million Geothermal Drilling Program (GDP) has been awarded to MNGI Pty Ltd (a wholly owned subsidiary of Petratherm Ltd), to fund the Paralana Geothermal Project, a joint venture with Beach Petroleum and TRUenergy.

The Company will inform the market of the terms and conditions of the offer as soon as they are provided. The GDP, announced in 2008, is available to those companies that are able to commit to a drilling program on or before 30 June 2009.

The Company is most encouraged by the recognition of its project and commends the Federal Government on its initiative.

The funds offered will contribute to the costs associated with the drilling of the 4 kilometre deep hole commencing at Paralana in mid June 2009.

Yours faithfully
