Not sure what the word game is here. You made an unsubstantiated claim and I showed you evidence countering it.
I have no problem accepting that they've got quite a fine material which likely helps recoveries as long as it's permeable. I've got data that I've captured that may indicate a similar correlation for recovery vs particle size down to at least before a point before it could turn into something that is hard to de-water.
Weathered granitic clay can also be quite fine, example from my turf pictured. I suggest if you want to continue the conversation, reach out on X, if not we shall leave it here. I don't see any utility of continuing discussion on this topic without further references or sources. I wish BCM well, looks like the capital efficiency is certainly there - as expected as for in situ recovery and that's more or less the only currently profitable extraction method for most ionic clay deposits.
