I would hazard a guess that a takeover is in the works. Its funny how San has never done a sharholders protection agreement. It is almost like they are waiting to be taken over.
There is a rock solid shareholder's rights agreement already in place and it was updated previous to last year's AGM. Any takeover would have to be on San Gold's terms and be similar in structure to the GEA / G agreement where both parties were ready and willing to do a deal.
The white knight may have something to say as well.
