The figures I get for a the 1:1 strip ratio 30 million tonne resource are putting all the Capex cost into the domestic sales. Over a ten year life of the 30mt resource -


Domestic -

20mt @ $21/tonne = $420m revenue
- $8.4m royalties
- $40m Capex
- $240m Operating costs

Gives a profit of $131m over 10 years or $13m/year

Export -

10mt @ $37/tonne = $370m revenue
- $18.5m royalties
- $140m transport
- $120m Operating costs

Gives a profit of 91.5m over 10 years or $9m/year

So a total profit over 10 years of $222m or $22m/year with another 450mt of resource still to mine.
