Macquarie commoditites report, page-10

WTF User23 - next time look at the time scale on the bottom of the graph if your confused by the "3 month old" data label. It clearly states what the month is - talk about DD! Clearly the increase from mid 30's to mid 50's already - with plenty of ore still on the docks, is an indication that ore price will increase.
Like Rusty noted above - re-run the economics with 2Mt pa with potential to increase when more fronts are opened up... perhaps time to update your Sentiment on this Speculative stock.
