switzer & some maths

Benny threw out a few figures tonight, $100 tonne cost and sale price of $250 tonne selling 30,000 tonnes a month when in production:-

$250 - $100 = $150 Profit/tonne

Then $150 x 30,000 tonnes x 12 months = $54,000,000 pa
Less 45% for joint venture leaves $29,700,000 pa.

Not sure if this includes shipping costs and price can vary of course but KPR market cap at the moment is $24,510,024.

Anyone want to check these figures and my logic?
