Hotmuck, i am just thinking out loud here, but if we are gearing up to run the Mill on a weekly bases, then i sure hope we have a significant stock pile of the high grade Hinge ore. My understanding was , SG1 had a high strip ratio ( under .09 g ) and the Cartwright is months away from developement. I see the hinge as the only source of ORE once they decide to change the main hoist, as we lose this capacity. I can see an extented time frame to change this freqency drive , as the programing of the unit starts after the mechanical instalation. I think back when dealing with the varibles in writing and programing drives, and in hoisting up 1900 tons , the time to ramp up of the drive and the stretching of the cable is a tricky problem, I HAVE NEVER BEEN TO THE COMPLEX , just talking out loud, but things never go as pland in the mining industry, lets change this hiost now, before gearing up to full production , and show consecutive cash flow increases. Long on the greens Traps7
