It's an open pit mine. You start at the top and mine down at the rate of 20k tons/day getting whatever gold you can out of that amount of ore. (about 1 gram/ton)

It doesn't seem right to assume, without any justification, that we will find more gold/ton than anticipated, or that VZ will allow more tons/day to be processed.

I just want to see some evidence before hearing crazy numbers thrown around.
