This is an excellent comparison of the mineral resources between TMT and TNG. In a nutshell, the sizes are remarkably similar, but TMT has roughly double the grade in titanium and iron content, and triple the grade in Vanadium, so ultimately TMT has those higher ratios shown in the total contained kt. We here it everywhere - "GRADE IS KING", and there's a clearly massive difference between the grades of the two deposits with TMT's being demonstrably superior.
