Batboy can you give reference and modelling which has been done to confirm the vein thickening, otherwise all we have is theory and no facts.

The only facts we have is the amount of gold per tonne that has been collected.

And the reverse of your argument is if the vein thins or falls away then the gold ratio will reduce and your guestimate will be wrong.

If you are gong to state such things as above please provide the evidence
