That 15Kt stockpile is a huge pleasant surprise to me, any idea how they calculate the payable nickel production that they only declare and sold for the quarter, I sure they need to declare the cash use for the quarter for those nickel that hasn't been sold which will have a result in their total cash flow balance, can someone confirm this?
If this is the case, it looking better than I thought. If not, at least they are making a small profit or breaking even compared to other nickel producers.
