GRR's management has consistently avoided telling investors what the life of the Savage River mine is - given that economic mine life is an intersection of product prices, exchange rates, recovery rates, production costs and tax levels, mine life will move around a lot so management's reticence is understandable (on this issue at least). As a shareholder, based on the information provided, I can assume that the mine should be cash flow positive for a good many years yet - how many is a matter of speculation.
