Tasmania
KUTh Energy's exploration strategy for the Tasmanian project is to undertake a comprehensive exploration program that combines a range of modern field geology and geophysical techniques. The eastern Tasmanian granitic suite will be followed at depth using geophysical survey methods such as gravity, magnetotelluric, aeromagnetic and seismic surveys. All results of these will then be used to more accurately target the most promising initial production zone and to develop a detailed 3D model of the thermal reservoir.
The existence of a modelled potentially economic thermal reservoir will enable the drilling of a deep (>4km) hole to test and refine the model, with positive confirmation at this stage leading to drilling a production well and subsequent injection well in preparation for proof of concept circulation and commercial upscale.
Primary tenement - SEL26/2005
This tenement was granted in 2005 and comprises 12,360 km2. Securing this SEL enabled the commencement of exploration activities to assess prospective geological structures and the potential for geothermal energy generation in eastern Tasmania. The tenement also includes metropolitan and industrial areas of Tasmania, such as Hobart, Launceston and the Tamar Valley.
Additional tenements - SEL45/2007 & SEL57/2008
SEL45/2007 (granted in 2007) is located to the south of the main tenement covering the south eastern urban areas of Tasmania. SEL57/2008 (granted in 2009) adjoins SEL26/2005 to the west covering the Great Lakes region. These two tenements bring the total exploration area in Tasmania to 18,151 km2.
KUTh Energy tenement boundaries (this does not show internally excluded areas). Total combined tenement area is 18, 151 km2.
As outlined above, KUTh Energy is employing a range of geological and geophysical tools to most accurately understand the deep geology of the project area, to define and access the potential hot rock geothermal resource. Various types of surveys that have been completed to date are;
Shallow drilling
Shallow temperature logging
Rock property measurements i.e. thermal conductivity
Gravity
Aeromagnetic
Magnetotelluric
Seismic re-interpretation
Defining the Hot Rock Target Zone
Six EGS targets in KUTh's tenements as indicated by the labels, named according to geographic region. Bold indicates a primary EGS target.
KUTh Energy's data collection and analysis activities are providing a consistent understanding of the project area. They provide a clear indication of the existence of a substantial hot-rock geothermal anomaly in central eastern Tasmania.
The anomaly comprises an area of about 4,170 km2 in which there is high crustal heat flow above 90 mWm2. It includes an area of about 620km2 with very high heat flow above 100 mWm-2. Our exploration plans are now focusing on a 50km2 area in which the zone of very high heat flow coincides with granite buried 3-4 km deep, as inferred from gravity mapping.

Concurrent with the exploration and analysis activities above, we are actively planning for the next stages of exploration and project development. Key amongst our priorities are the development of our 3D resource model, coordination of activities for deep drilling and proof of concept, and planning for the establishment of power generation, network connection, transmission and commercial operation.
