In the course of compilation of geological data for its regional mineral
exploration programmes on the Curnamona Craton, Havilah Resources NL became aware
that an area west of its mineral tenements had the key requisite
ingredients for a potential hot rock geothermal energy source.
In contemplation of the energy needs for its proposed development at
Kalkaroo, Havilah applied for a single geothermal exploration licence
(GEL 181) over what it believed was the key area. Subsequently, after
conducting further research it was decided to apply for three adjoining
GELs (208, 209, 210). Owing to concentration on its basemetal and gold
exploration, Havilah decided to sponsor the formation and public
listing of Geothermal Resources Limited, a new specialist geothermal exploration and development
company, in order to raise new capital for the specific purpose of
exploring for hot rock geothermal energy.
The company listed on the ASX on the 21st March
2006 under the code GHT.
- Geothermal energy is a unique form of clean, renewable and continuously
available energy, which will be increasingly in demand in the future.
- The science of generating geothermal energy from deep hot dry rock
sources in South Australia has now moved from theory to reality with
recent published successes in drilling and testing by a number of
- Geothermal Resources Limited has two hot dry rock exploration projects
that are located within high heat flow areas of South Australia.
- The Frome project is situated in an area of known highly radiogenic
granites in the Curnamona Craton region south of Lake Frome.
- The Penola-Robe project is located at the northern margin of the Otway Basin
in the South East, in an area of abnormally high heat flow.
- In both cases the key ingredients of “hot” granites buried by a
sufficient thickness of insulating sediments appear to be present.
- Both project areas are well located with respect to existing electricity
grids and infrastructure, that would enhance early development.

North and South America, Africa and Europe, marketing the
Vulcan mining system. This experience has provided a
broad understanding of orebodies and of the role of 3D geometry
in structural geology.

Dr Chris Giles is an experienced
geologist having supervised exploration programmes for a
variety of organisations all over the world. He is Executive
Technical Director of Havilah Resources NL, in which capacity
he has been jointly responsible for the definition of the
Kalkaroo and Mutooroo copper deposits in South Australia.
During his career he has worked on exploration teams that
have been directly responsible for the discovery of several
operating gold mines. Prior to jointly founding Havilah,
he was responsible for ground selection and supervising
initial exploration programmes that resulted in the discovery
of two substantial gold deposits in the Mara region of Tanzania,
by East African Gold Mines.
