There was some 'Substantial Holder' action yesterday (16 August) on Blina Diamond's side of the Blina/Kimberley fence.Blina announced that Merryl Lynch will hold 14% of Blina Diamonds compared to its previous 8% holding.What that suggests to me is Merryl Lynch saw increased investment merit in Blina's recent drilling results.I did too (when Blina's drilling results were announced) and sold half my KIMs to buy some BDIs.Now begins the waiting game (for Blina to hit pay dirt big-time) that was rudely interrupted (for my KIM holdings) by a very pushy mob from London.
