I agree the Buena Vista announcement is a good one.
if you convert what US steel spent in the 70's on this resource into 2010 dollars RHM have got a bargain. US steel spend in todays dollars would equate to about $20m Aus plus you add in the time saving of 5-6 years and it looks very good for RHM.
In addition they have the Naracoota project which could well provide a lot of cream on top of the cake.
