Debt free and SP stagnant?, page-37

I asked a similar question, but alas, no answer

If the price of gold, say got up 10% or 20%, is there a motza of 'rubbish' dirt that was not economical at $2500 oz, but is ok at $3000 oz. How much of this rubbish dirt exists; I really consider POG will go up over the next year. If that happened does the LOM double. Now the profit would be no more per oz (now we are, what, $1000 cost vs $2700 for 5 years of 30k oz). Is it possible ANOTHER 30k is feasible, that costs $2000 to mine, but POG would be $3700. Same margin, but suddenly a double mine life (obviously the profit on the current reserves can double, but I am interested in the longevity - with a higher POG)

I guess we need not worry about that if they just find another resource in their scratching around.
