RE:RE:PP before NR on underground= something went TlTS up Mate, CEO said August 6th NR VERY SHORTLY.
PP before NR on underground means there is nothing positive to report on underground. Otherwise they would have released that first and only then done a PP, since they would have gotten a better price.
Its very likely, that something has gone seriously wrong and market will price out the underground possibilities in the coming weeks. That would mean a share price back at the 0.15 cents lvl. Thats over 50% lower.
