Spot on, not Rel. In some of the old stopes on the upper levels you can see where they have hand stacked the waste rock. I think i read a KAU announcement some time ago saying that they may do some bulk mining (possible long hole open stope) in some areas where the rock adjacent and in between the main qtz lodes carries a consistent but lowish grade over many metres. This will give you a large increase in tonnes but drop the overall head grade substantially. Depending on the ratio of Long hole open stope ore compared to the narrow stope airleg ore will decide what the overall grade will be thru the mill. This is a real rough guess here but if it is 50/50, they would be lucky to get an overall head grade of 10g/t. Centennial mining did a long hole stope and grades were well below expected. An old adage says "grade is king"
