'future sx' @Kal very likely relates to primary SX, the initial circuits that separate SEG/HRE from NdPr then LaCe, not difficult to understand the efficiencies of streaming the three primary products in their required volumes to respective final separation & finishing plants, not least reducing residues in host countries.

Obvious one is eliminating the inefficient dogleg, perhaps sovereign risk, for SEG/HRE via Malaysia.

Eliminates the need for large primary SX circuits US.

Frees up assets LAMP to rededicate to NdPr/NdO, perhaps La but that may require another stage Kal to partially separate LaCe, a Ce discard if you like, probably inevitable at some point given growth profile Ce vs NdPr.

Knowing how Lynas strive for efficiencies at every point something along these lines is inevitable to maximise the opportunity at Kal, suspect we'll find the project subject to Oz value add export grant, perhaps US assistance.

Interesting some preparation work appears to be underway.
