Ann: Recent Drilling Intersects High-Grade Copper, page-8

You are adding tonnage to resource , but its pointless as once you turn it into a reserve it will be uneconomic to mine as the widths are too narrow for UG and narrow widths also means high strip if OC and high strip and low grade is well - uneconomic most of the time .
It becomes a BS exercise , there are enough drill holes to now show all they have done is steralised the ground for putting in pipes or a plant .
Maybe throw in a couple of deeper holes down dip to see what it looks like if they have funds but probably better to move on .
