Ann: NTU Hallgarten and Company Coverage Update, page-88

I'd wait a couple of years before calling $684kg fantasy. Just last Oct there were a couple of HC posters calling a SS Cobalt Project a fantasy because it was based on cobalt price 20% higher then the $26/lb it was at the time. Less then 5 months later they are now 40% higher.

As you've probably seen in his disclaimer he doesn't own NTU and has no reason to pump it or follow it closely on HC. You could put it to him but even if he sees you post it may take him a while to answer as he probably follows dozens of companies. Not everyone is as lucky as you to have everything invested in just one stock and have the time to pump it 24/7.
Since you have been informing NTU holders for years why not go one step further, drop in at the next AGM and ask GB directly anything that you view as fantasy then post his answers here. I'm sure that other NTU SHs on HC would appreciate it and would like to know the answers as well.
Cheers.
