There were more than 140mln shares issued at 5.7c as part of the placement, with 1 for 2 free option. Some of those people would have been in for a quick buck. So they sell at a profit and free carry the options. That trade that @Jaliso identified above is part of it.

For every seller there is a buyer, the more volume and the larger the transactions at these levels the better. It means that someone is taking a long-term view. For example, if someone buys 1mln shares they are not there for 10-20% profit, more likely 100% +, because they would need the same large volume to exit.

So look at it as a good sign. I think people are taking positions in anticipation of the next few months.
