I looked carefully for the thread on ore dilution and when I couldn't find it, I posted on this thread.
Not sure that input grade is totally unrelated to gold in tailings anyway.
For Example: If a mine had 2 g/t into the plant then you cant get 8 g/t out to the tailings.
I suggest we do not make the threads too regimented lest we discourage posters.
...if you disagree you could ask for my post to be moderated -otherwise please refrain from giving me instructions (especially in bold) as I'm not in the employ of Hot Copper.
