“Ortahaza failed on what could be simplified as flow rate issues. In conjunction with temperature, this is the primary mechanism behind viability.”

I would argue that GRK understands this better than anyone else in Australia. This is why they are working with CSIRO and I believe that their strategy will be revealed in due course.

“and there is no reason for GRK to warrant any more attention than URO or even TEY.”

I would suggest experience is the difference between the GRK and any other company. Even if they have GELs in prime locations with favourable stress fractures required for good flow rates.
