Can't edit my post, just realised I was using 22.5% as the oxide discount as opposed to 25%. Would make the last calculation in my post NdPr price per tonne as US$37,194. My calculation may be slightly on the low side. Didymium oxide (the mixture of NdPr) is at around $40,600 as per price.metal.com. Not sure how much prices have changes since Hastings December preso where I based my numbers off. So I'm within about 10% either way
