RE: Production and costs when Galena shaft is operI'll leave others to speculate on what the production increases will be. As for cash costs I expect them to remain more or less constant as the production increases, since that is what has been happening up till now. The main variable seems to be fuel costs. So if the total cost right now is $12 - $13/ oz and then production increases to 3.5 million ounces, the new cost per ounce should be about $8.70-$9.40
