OK so revenue is 108 million tonne multiplied by USD$150 equals 16,200,000,000 or USD$16.2 billion.
Cost is USD$350 million + operating cost of USD$37/tonne which is 37 multiplied 108 tonne equals 3,996,000,000.
3,996,000,000 + 350,000,000 = 4,346,000,000
Revenue less cost: 16.2 billion less 4.4 billion equals 13.8 billion. Looks robust but need to look closer at capex relating to benefication.
