MREC is quoted on the Shanghai Metals Exchange, : https://www.metal.com/Concentrate/201102250378
Although they only quote for one grade ie 42-45% REC
Prices will vary considerably depending on the actual mix of individual rare earths within the concentrate,
And a Premium will be paid for higher concentrations eg a 90% con will fetch considerably more than twice a 45% con

All will be revealed in the BFS, not long to wait now.
