change in substantial holding, page-5

Hello everybody,

I've got a few questions if anyone has the time to reply I'd greatly appreciate it.

1/ What is Regent's stake in BCI restricted to, is it 15%?
2/ Why are they chosing now to increase their stake in BCI? Is it fair to assume that if Regent is buying for a Chinese interest, that BCI has recently finalized a deal with this Chinese interest and we are now waiting for results from the test pit before the deal is to be announced?
3/ Why are Regent buying on the market? Or have there been a series of cross trades going on between Regent and probably Agronaut?
4/ Any ideas who bought the 4 Million shares? My thought was it was a Chinese interest or Consmin. But it now seems to be that the Chinese interest, (I'd put money on it being Baosteel) is buying through Regent. So is Consmin via someone like Cape Lambert more likely?
5/ If Regent are restricted to 15%, can I assume that they wish to increase their stake in the future to the 15% limit? Could we see one last big buy by Regent on the market of around 800,000 shares shortly before a off-take agreement is announced?

Just trying to predict what may be about to happen. Thanks.
