if i am not mistaken, and its not specifically stated, but BRMs 1 bill/t is predominatly magnetite.
They have about 50 mill/t of Haematitie and the rest is a low grade ore that needs benefication. I believe this is a costly process.
this is not a downramp of BRM as i tried to buy at $1.66 yesterday (missed by 2c with no one else at 1.67 hehehehe).
cheers
