Ann: Pause in trading, page-60

This graph has been around for a bit and I ripped it off the TVN latest investor preso
"Golden-boy" GW over at TVN isn't shy about throwing shade on competitors in the V space despite being a relative new boy on the block saying in latest ********* interview that most on this list will "wither on the vine" no doubt referring to AVL & TMT who he has taken earlier swipes at.

TMT & AVL have detailed Mining and Reserves tables presented yesterday

Can someone with Metallurgical knowledge please explain to me in laymans terms:
1) how the Speewah resource can claim a 2.40 concentrate grade of V which is comparable to Largos 2.45 but off an inferior resource grade of 0.3 as compared to Largos 0.78,
2) how AVL & TMT average resource grade which is comparable to Largos at approx .78 produces a less concentrate grade of 1.40

Thanks in advance
