If I have it right, an important part of the deal is that the Chinese will source financing for development, as well as investing directly in the company. Was $800m mentioned? Together with the $180m, they will have enough for the first stage of production, at half of the final tonnage per year level quoted by the Globe & Mail. Should be easy to go from there to full production, with money rolling in steadily - I think their anticipated costs per ton are well below the prices projected over the next few years, certainly they dont need $1700 a ton to turn a profit. Economies of scale help of course, but costs in general are quite low relative to other known deposits.
