I believe, that if the company can get their paperwork up to date, and release a pr or two with positive results that interest will pick up and so will volumn.
I think how high it goes will depend on how low some willing to sell at. And based on the enthusiasm shown by some on this forum, I don't doubt that ears will be whispered in to spread the word, on the newest member of the current list who appears to be sitting on at least one multi million dollar find, with another site which appears to be a similar find.
I have seen other stocks with less potential run on some decent news.
The biggest issue this stock has in my limited experince with the stock market is the ability to get their paperwork caught up. If they do that, who knows.
