Need to read this, page-13

so currently 1 tonne pure Nd is 116,000 aud/ tonne convert 550,000 CNY to AUD
NdFeB only contains 27-30% of Nd. 1% boron at 8000/ tonne and 69% Iron at 110/tonne. So roughly 3 tonnes Nd to 0.1 tonnes of Boron and 6.9 tonnes of iron. This makes 10 tonnes magnets=$ 349500 for raw materials to make 10 tonnes magnets. *150= 52.5 million aud roughly for raw materials to make 1500 tonnes of NdFeB (30%nd69%Fe1%B) alloy
if sold at 100% mark up thats 105 million annual sales. To make your 300 million sales based off 1500 tonnes asm wouod have to mark the alloy up 600% from cost of raw materials going into the KMP.
I think your 300 million annual sales is very inaccurate. my guess is its 80-100 million in sales/ year
