Hi Launboo, feel free to believe whoever you want, but perhaps try to discuss logically rather than emotionally, as your figures may possibly be misleading other viewers.
Lithium prices are quoted on a percent of concentrate basis, so the Lithium price in Off take agreements is for Lithium concentrate at the specified percentage, say 6% with adjustments for variation of percentage.
My understanding is that Tantulum prices are for the contained Tantulum only (seems to be what your "expert" is saying as well, not a concentrate price, so first you have to work out how much contained Tantulum there is and then apply the price.
It seems nonsense that you would value a 1 tonne concentrate at 30% the same as a 1 tonne concentrate at 20%, which is effectively what your calculation does as it doesn't take into account how much Tantulum is contained in the concentrate.
All just in my humble opinion and I make no claims to being an expert.
Thanks
