Actually I didnot minus the cost, coz I donot know the real cost, that's why I said roughly calculation, if put costs on, say USD2, 500/per ton for Bromine, and USD 10,000/per ton for Iodine, so, 

1. Bromine
(4,500 - 2 500)*10,000 = USD20, 000,000 per year

2. Iodine
(20,500 - 10,000)*10,000 = USD105,000,000 per year

ASN shares 500,000,000

Roughy earnings:
1. Bromine = 20,000,000/500,000,000 = USD0. 04

2. Iodine = 105,000,000/500,000,000 = USD0. 21

Industry PE = 10 times. 

So, ASN share price for Bromine only is USD0. 4
ASN share price for Iodine only is USD2. 1
