Another 330 Million for platinum. Costs will be zero, as the revenues for Nickle as a by-product kick in. Yep, different reasoning. Vale tries to sell its Nickle business for 6 to 7 Billion, no interest in the market. Glencore may try to do the same in the Chromite market as they did with zinc, guesstimate another Billion or two (discounted at 3 %), provided broadband is coming to you by summer 2018. Pls do your own calculation. Who cares about expiring options anyway, there is yet top priority to deal with other han options granted to people who left the company.
