By the way, another Aussie geothermal start-up Petratherm, 
made an ASX announcement on Board Room Radio today:

New Geothermal Energy Project near Renmark 

Petratherm Ltd is pleased to announce that it has expanded its geothermal 
project portfolio in South Australia, following the acquisition of two 
new Geothermal Exploration Licenses (GELs), located 26 kilometres 
northwest of Renmark, in South Australia’s Riverland Region. <snip>

The two new contiguous GELs capture the deepest portion of the Renmark 
Trough, a depression of the Murray Basin. The estimated depth to 
basement, based on seismic data, is 3.5 kilometres.  

Measured thermal gradients in the area are elevated and potentially 
around 40 degrees per kilometre. The current exploration initiative is 
looking to test a conventional geothermal model of  directly extracting 
hot brine waters from aquifers near the base of the trough. 

Two high voltage 132 KV transmission lines run through the tenement 
holding. Network analysis of the transmission system has confirmed that 
this is a strong portion of the National Electricity Grid and could 
easily support a large scale geothermal development.  

Whilst the region will not yield as high a geothermal gradient as 
Petratherm’s flagship Paralana Project, the licence area is attractive 
for geothermal exploration by virtue of its proximity to large capacity 
transmission infrastructure and the potential for the utilization of 
naturally occurring hot geothermal waters at depth, requiring relatively 
lower engineering costs to develop. <end quote>
