I'm no specialist in mining costs, but I thought Newmont said some of their mine costs per oz were starting to get high in the $400 range and that was on the high end. Most average costs were less than that.
I'm leaning towards the $150-200 given the quality of FDN, and trying to recall some conversations we had shortly after the 43-101 came out.
But again, I stand to be corrected.
