Alright the reason BHP are not interested is because they are a diversified miner. Iron ore is by far their biggest product and they have a fortune of the stuff.
They have been targeting oil, gas and potash for years purely to fit in their portfolio, that is all.
This is a good example, if an investor bought FMG, AGO, MGX, GBG years go for a quarter of their current price and they had some more money to invest, they would not touch SDL. Not because its a bad company, but they made a killing of iron ore shares already and would be looking at divesting into other commodities or sectors.
Thats what BHP are doing.
