I've got an unusal deposit that has a big juicy nugget of high grade at depth, and low grade material above it which is still above cut off.
If I stage the whole lot I get no pit until RAF0.4 and this give me quite a sizable first stage, as suddenly it gets sucked down to the high grade. Running this in the sheduler mines out the entire stage a bench at a time, but thats inefficent on the stips and is killing my NPV.
I can create a number of earlier stages by ignoring the HG material and code them into the BM or pit points file that would improive the shedule but I cannot see any way to force a manually designed set of stages in the Analysis form. Any ideas? I could try playing with very tiny RAF incrments but from what I've seen once I hit a certain point it will go from zero to hero.
