Here is another take on your calculation. You will notice that I have increased the Ni equivalent to 3.5% to account for Rhodium. We do not have final numbers on Rhodium so this of course is speculative. I have also increased the buyout to 30% as per PM. I have given scenario if we prove up, 6, 15, 30, 50 and 100Mt of ore just to keep the dream alive!
