See also the detail about "landed" pricing, which gives BHP's Australian iron ore a big advantage over Vale's Brazilian ore. Might be an incentive for Vale to increase its efficiency / lower its costs more to compete.
The other possibility is this: with all this cash coming in, if Alloy Steel's wear plates are as good as we think they are, if you're a BHP, why not just buy the company, so no one else can use the wear plates (sort of like how Starbucks bought the company that makes the Clover machine)?
