They thought that larger lakes provided more options, bores are more challenging than trenches, longer term pumping tests more desirable. In their opinion the biggest risk was recovering the brine, logistics was a secondary concern. IMO this narrative shone a light on Lake MacKay.
It begs the question, what is their take on Lake Way?
They covered SO4 when Lake Wells was the go. Lake Way is a smaller lake, more dependent on bores and the pumping tests have been relatively short term without a single new paleo channel bore being developed and the basal sands resource extrapolated from essentially a single WMC bore from the early 90's.
