No, I for one do know why they are that high, and I do know what they did (are doing) about it.
I won't post it because I have nothing to "link to" or "point to", so ya'll will just say that I'm an idiot or liar or some odd crap...so I won't bother.
The one thing you can not do is argue the FACT that the current waste percentage is running 70%. Those number are in the BK Interim Reports.
You can not argue the reasons "why it is" because you have no factual evidence to support your argument.
A: Current waste % is 70%. How do you know what the current waste is? Do you have daily reports from the mine showing 70%?
Waste percentage for September was reported as 70%. Agreed. Fact. But that doesn't mean it is currently 70%. It could be better. It could be worse. But it is not a FACT, unless the daily reports can be provided.
