Using your calculations with the lower price of $450 per ton and this could fluctuate up to $650 we get the following:

60,000,000 cr2o3/tonne x $450 = $27,000,000,000

2,700,000,000

If we gave a discount say a worth of 10% of total it would be divided by 132,800,000 fully dilluted shares = $20.33 per share just for Chrome
