I don't think you read my post carefully. I said that if additional resource was found to be viable then they would have quick and easy access to old stockpiles to process. Not having to bring the ore to the surface in concentrated piles makes it quicker and easier.

DeltaVee took a number of 4% from results ranging between 1-18%, estimated the size of the resource which you cut by two thirds, and presented a current value of copper which you then devalued by adding in estimates of transport and processing. This figure was then multiplied by five to extrapolate out to all five stockpiles. Both your estimate of value DeltaVees fall in the same margin error range. You could divide your number by ten and multiply his by ten and still not cover the full statistical error in the calculations. If you can't see that then its you who are blind.

But the point wasn't the exact size or value of the stockpiles, just that they are a (realisable) asset with value.
