I don't quite understand your question.
The lake contents are made up of porous solids and "brine".

The potassium salt content per cubic meter of brine in LD is 150% of the brine in Lake Wells.
MR has demonstrated that potassium is close to 90% recoverable from LD brine.
Furthermore MR has determined the evaporative sequence for LD brine under field conditions.
Other Australian salt lake hopefuls can't assume that they will have the same evaporative sequence and thus the same processing requirements.
At the very least the guys at lake Wells are likely to require ponds 150% the size of those at LD to yield the same amount of SOP and their end product may be processed in the same manner.

I'm sure you already know this stuff.

MR has done a lot of the work that the others are yet to do.

No sarcasm intended.
