Others have now jumped in to back either side (eg here and here), and some egos may come into play, but at its is crux is one important issue: when Kelvyn Alps and Pheonix (and Sasako) talk about a 50/50 split with landowners in the proposed alluvial mining venture, what are they splitting?
In other words, 50% of what? Saiki's query was: "after the gross revenues before deducting any cost and expenses of the operations or on the net profit after tax?"
This would seem to be a good thing to clear up from the get go...mining is the new logging, and like the old logging, who gets exactly what and how is the $1 billion question.
Watch this space....Alp's answer should teach us a lot - especially if it is silence!
