Like I said, if Oregate could get its recoveries up in the mill they would not have to worry about the mine. Their gold recovery is only 60%. That is what is holding them back. Metallurgy. They have to spend a million dollars in research finding out a way to get better golds. They should target 80% gold and 90% copper. They really have to put the thinking cap on. Is the gold too fine? Locked up in quartz? Not floating with the copper? Not coming out in the copper refining? Geco and Flin Flon where metallurgical stories too. Their economics were dictated by engineering companies like Mills Crowe who found the best solutions of their time. Flin Flon's economics was saved by the cyanide recovery process of Mills Crowe. Hell if I were Northgate I would crush to 4 inch, scalp the fines put the pit stuff through an ore sorter and shrink the mill to 10,000 tons per day. Better to take 75% and run a paying grade then fight the low grade and lose 40% anyway. EC<:-}
