Kevin has no control over geology - the eastern cutback is all about stripping out the well documented, well broadcasted "waste material" to get to the higher grade Iolanthe vein structure

The mining strategy at some point has to simply "bite the bullet" and get rid of this waste which unfortunately comes at a cost will little to no recovery from this area - but once the waste is out of the way, the veins will be thicker and richer as they go lower - I suspect they have just about reached that point now
