I'm guessing the Dow low might be something like 1929-32 , so we might be talking 2011 for the gold/dow ratio to approach a low, assuming that Tyhee starts building a mine around then , and as I think you have said the reserve will grow when they start mining how does 2013 sound? thats "only" 4 years away. Only guessing here, but given that companies like Homestake did very well throughout the 1930's we could see a decade of high prices for companies like Tyhee.
