This isn't rocket science.
It is about SOP grade and SOP recovery.
KLL have question marked recovery at RWD, Ruane has published results showing 80% plus.
The grades at RWD and KLL are not that dissimilar. In my opinion claims of 30GL for 300Ktpa versus 70GL for 400Ktpa don't add up. I don't care if you think the Germans have the credentials.
As for the trenching, the Germans are modeling, they haven't done any test trenches at Beyondie yet KLL are happy to state that RWD needs 200km when in fact RWD has done tests and calculate they need 50KM.
