The only ridiculous statement there is that "$67.40 makes up 87% of Input costs." ~ insinuates that Total input costs are US$77.50 !

Input costs for WHAT ? 1kg, 1ton, N35, N52, N55, Magnet ?

Certainly not for a 1kg RE Magnet, given that a 1kg NdFeB (N52) Magnet blank sells for just US$40.56;
I can't see a Chinese Magnet manufacturer selling their product at a massive loss ?

Now consider that that $67 is the subsidized cost of 1kg of Nd, (to a Chinese manufacturer)
And that each Magnet uses around 30%Nd, thus giving around three magnets per kg
Take that US$77 ( your 100% input cost) and divide by three ~ gives a manufacturing cost for that $40 magnet of just US$26.
That indicates a US$14 raw profit margin made for each kilo magnet or ~ $45 per Kg Nd processed

If we take Saltends 4,500tpa of Nd production and turn it into Magnets that will add ~ US$200M to our bottom line profit !!!

Which clearly demonstrates WHY Pensana intends to eventually become a Magnet Manufacturer .
