Ann: Pit Inventory for Nueva Sabana Mine, page-91

Putting the closing sp in perspective:

165,000 shares for a staggering sum of $A 2,970!! The first trade of 1.8c at the start of the price debacle was a cross trade.

So @Sweetsound, to answer your questions:
1. Does someone know an adverse outcome is on the way or perhaps further delays? 2. If the outcome is positive and so close then why would anyone sell this low?
Answer 1. Most probably not. Out of the 1,496 shareholders in AAU 146 hold 5000 shares or less. These holders aren't even in the TOP 1350. So I doubt that they would be privy to such info.
Answer 2. Just some close of business shenanigans. This represents less than 0.0183% of the market cap. Nothing to worry about.
