"Final heat-flows recorded from exploration drilling have increased, with modelled temperatures at 5000m depth being upgraded to 247-248°C," the company said.
"Drilling was conducted just 230m from the national power grid and 4km from [the township of] Parachilna.
"High modelled temperatures were recorded over a continuous area of at least 500 square kilometres, highlighting the potential for the company to establish a new geothermal field north of Port Augusta."
Torrens is calling this field the Parachilna discovery.
Results from the Nazgul-1 and Sauron-1 wells indicate heat flows of 106mW per square metre. Gollum-1 is even hotter at 111mW/sq.m.
Results have yet to be returned from the Gandalf-1 and Balrog-1 wells, but the final equilibrated values for the first three wells are well above the company's stated target of 90mW/sq.m.
Indeed, according to Torrens, these results are above the averages recorded for the Cooper Basin, which has traditionally been the focus of geothermal exploration activity in Australia.
"These results are higher than temperatures currently being exploited for ‘hot rock' geothermal power in Europe, and amongst the highest being evaluated in Australia," the company said.
