I don't think we will see any noticable increase until we get some good drilling news.
The reasons are partly because 1) all of us gold bugs investing in juniors we have basically spent our money or are already very overweight and 2) new big money will only go into producing mines such as Barrick
Conservative investors will only go after big cap gold producers with track record and limited volatility. Myself as a small speculative guy I am already loaded with juniors.
We need good news showing economic potential, period! Of course a dramatic increase in the gold price will help, but it is not enough
