Hi Heeman, I believe in the last resource/reserve upgrade in the good old days when we were just plain old TAW a fair bit of it came from lowering the cut-off as it was economical to mine. Given the falling selling prices would likely make more uneconomical what's your thoughts on the possibility they may need to raise the cut off grade , thus resulting in some decline in reserves/resources, hopefully compensated by some new discoveries?

Thanks
