That is a very interesting find.
On a Life of mine basis PLV output of 80Mt (20 years)
@$700M capital is $8.75 capital per tonne.
Personally I think PLV Life of mine output will eventually calculate to 100Mt
The RHM is 17.5Mt @$161M capital = $9.20 capital per tonne.
Some really interesting options in the deal between RMH and HBIS.
