Sorry ORD but I'm completely underwhelmed. You call a couple of 4-wheel drives burning up the countryside and a lump of bauxite price sensitive?
What is the market supposed to do with that kind of information when the SARCO boys appear to be so lazy that they couldn't even be bothered to dig out that rock. That might be the top of a boulder but we'll never know.
IMO you're better of sending those pics to an Off-Roading magazine.
