I would think that the management of GRK would have a strong belief in their current projects and are busy developing them to their best potential. In this sense I doubt they view their Cooper Basin GELs as insurance, but rather as increasing their range of possibilities and planning for well into the future based on their belief that geothermal will provide a significant source of electricity to the grid.
They have also included desalination of seawater as another potential for their business, and this is another area of great demand for SA. So I see the management team of Greenrock thinking well in advance in more than one direction and can see them growing substantially over time. To the great benefit of shareholders.
