cdu's mined copper reserves, page-15

We were given percentages early in the stockpiling.I that is not good enough and greater volume is needed for more accurate figures,then what volume?
1 million 2 million.Will they be accurate or will it be at 10 or 20 mt or not till 30.
They will have hit all the diff areas by 1mt so that would give us a good idea.
Unless its all over on dso stockpiles at +20% because it seems they have mined plenty to add only 100,000t to the long term stockpile.
All good fun.Happy to get the good announcements close together
