company value

44 mill MC at the moment. 2 mill tonnes a year target x current 295/t approx. 600mill. 298 capex I think, lets say paid off over 3 years. 100 mill a year. Cost to produce the 2 mill tonnes lets say 50%?? not sure but 300mill for arguments sake??
So costs for first year around the 400mill mark after selling 600 mill worth leaves 200 divided by 1/2 to Enamco leaves us 100mill still 2 times market cap SP back up to 50c - 60c?
I know its rough but thoughts?
