@setfire2thehive I figure you might find this useful for your models. Was reading more into the Carina PEA and they have this gem:


The fact they state MREC market pricing only accounts for Nd, Pr, Dy and Tb, this also aligns with the below from Gavin Beer (Australian):


If you assume a 90% REO purity MREC, per Argus Hong Kong pricing mechanism you get 0.92 (NdPr, Dy, Tb) x 90% = 82.8% payability on the Magnet REO, same as I use in my models. Both these references suggest all the other REO are worthless for MREC. I don't know where IXR get their 70% payability across all 15 REO from, there is no reference at all to where that pricing mechanism comes from, and doesn't align with the references I have come across. IXR's studies released to market are light on details..

This may help simplify your models if you only have to track 4 elements!
