Was looking at the latest NTU presentation from the Argus conference and had some doubts hoping someone can clarify.

On slide 5 it lists the Browns Range Rare Earth distribution for NTU where it says that Dy content is 8.8%, Tb is 1.32%, Lu is 0.6% and NdPr combined are about 4%.

Then on slide 38, it says the Revenue Mix for Browns Range will be 56% Dy, 22% Tb, 14% Lu and 8% NdPr.

My question is - how do the revenue mix depend 56% on Dy when Dy content in the overall distribution is only 8.8%? Same goes for Lu, Tb and NdPr?

What happens to the 56% of Yttirum or Gadolinium or Erbium that are present in greater quantities?

Thanks
