here's how i see it, page-9

Mr Chung and KookE,
so my value in ground in my post of 25/7 of 67cents per share is fully endorsed by your calcultions and double that [$1.20] when the exploration targets are met as they mostly are with further drilling.ie 1 billion tonnes.
We have also learnt since from the last ZYL report that Sulphur and Phosphorus levels in Kcentral are miniscule and therefore more valuable.Looking forward to the BFS in October.
Cheers Chooky
