China Update

Several new prospective geothermal sites have been identified by Petratherm in China.

The sites were identified in a recently completed Engineered Geothermal Project Prospectivity assessment for China, which formed the basis of a Asia Pacific Partnership grant awarded by the Australian Federal Government.

Petratherm Managing Director Terry Kallis said the program identified several new prospective geothermal sites for electricity generation, specifically in the South East of China, where most of the new demand for electricity is required.

“Importantly, economic models of these sites indicate potenitally good commercial returns,” Mr Kallis said.

The company is continuing talks with potential local joint venture partners, local governments, and the national government over sites identified in Jiangsu and Fujian Provinces.

Petratherm’s Exploration Manager for China Dr. Wenlong Zang, presented today at the inaugural South Australian Resources Chinese Investment Congress.

A copy of his presentation, which summarises some of the recent Chinese project work, is attached for your information.

Mission

“ to explore for and develop, emission free, geothermal energy projects that are commercially sustainable ”

Business Model

“ to develop a portfolio of quality geothermal energy projects conventional and EGS – for power and/or heat – where there is a favourable combination of geology and market conditions - and introduce joint venture partners with skills, risk appetite and funding ability to further develop projects through to production”

Finding Hot Rocks

In Australia only 7% of the continent has sufficient well hole data
