There has been a lot done and results obtained since the last PP. Noront today in the 'Ring of Fire' simply has confirmed more mineralization. This brings with it much more assurance of current value and increases the likelyhood of additional finds.
As an investor at current price levels this adds greatly to the comfort level while you sit out the swings in market price that Noront will be going through.
While we can guess what the value and comfort level will be in a month or two we just have to wait and see. A market price of $8 requires more reports of mineralization or proving up with more drill holes what now is known.
Several months ago I never would have been comfortable investing at current levels as just too much risk vs reward. Today with what is known it is an entirely different situation. Tomorrow you may well find other well heeled investors entering into the market for similar reasons.
