Century mine life ends at approx 2013. That is 4 years away. It would be a brave man to put their money into a mine with a life of 4 years that is currently barely profitable, esp with the numbers of Zinc mines that are closed down and can open at short notice.
It is hard to find data to support your idea. While I agree that ZFX was very profitable when Zinc was at it's peak, the price rise encouraged lots of new mines. I find it hard to foresee those Zinc prices reappearing in the next 5 years
