Ann: Record Quarter of Gold Production for Blackham, page-367

You said a few months but had no evidence from what the few months claim is from? You have no more mine plan information yet you assumed the worst, that's my issue with this discussion. If you don't have solid evidence or rather, any evidence at all of an outcome then don't suggest the outcome. I would say the same to a positive poster as well as a negative, it's just bad form to create a scenario from no evidence.

Furthermore, in your situation your grade is wrong. Where did you get 1.3gpt from?
