central australian potash explorer woos chines, page-3

It begs the question will this delegation also cast an eye over Lake Disappointment which to date is the best potash resource in Australia and will only get better with the recent Geoscience data.
Do any of you guys know how closely RUM is now working with RWD. Has there been any hint of collaboration between RUM and RWD at Lake Mackay considering RWD has already drilled the larger half of the lake?
It may be a big lake but it would make a lot of sense to share infrastructure including ponds.
