BlackRock hold the shares in a number of investment trusts, such as BlackRock World Mining, which has moved to a more dividend paying position recently.
Riskisprofit read the article the buy out price was 13p but got rejected so they came on board as major share holders they have been very supportive over the years. Mind you I would be supportive if I was getting 20% interest.
So you bought because you think the main share holders will keep stumping up the Capital until they can get the plant running smoothly because they know if that happens they will get their cash back and some.
