"In our present situation, most tend to forget that the rate of payoff of their resource must be counted into the effective value. If you have a deposit that is worth $1,000,000,000, but will need 100 years to finally sell the last of it, you must calculate this at that rate of return, it never is as pretty as it originally appeared."

Besides bringing that value back to present time, many forget that they never obtain the in-ground value to start that calculation. At best (which rarely happens) one should start with half that value due to expenses that are incurred to get that resource from in-ground state to sellable metal.

So in the above the value used for translation to present time should be about 300 to 500 thousand $, not 1 billion.

So these two factors contribute to the majority of the misunderstanding that many retailers have regarding undervaluation of their stocks.
