RE:RE:rumour has it,I can see things picking up once their threshold is below 10% and no longer reportable on the "Insiders" selling/ buying reports.
I think, perhaps, the company is awaiting that until we see a jump in share price.
as Birch1 indicates, it would be interesting to know who is making the private $1 million share purchases. Those are huge sums of money at a time. Someone, or several persons are sinking huge cash into those private deals.
