Lol do some research mate, I have covered this in the DSO revenue thread, but for your sake:
As quoted from the ann today HB just give an indication of Mn 44% from metal bulletin @ $6.18 tianjin port.
At a supply price of $170 US and High Grade Mn 49
Profit = (49 x $6.18= $302.82 US) -170=$132.82 US per T =$173 AUD per T
Annual Profit = 103,162×173 = $17.8 million minus transport costs.
Plenty of upside my friend!
