Negative Cu production cost

posted on Jul 15, 2012 04:33PM

I've been puzzling over what our new cost per lb of Cu production cost might be with the new 2012 RE. So far I like what my napkin tells me but I'm not very confident that I've incorporated all of the factors. I've looked thru the 2010 PFS and couldn't find a specific statement or section relating to negative production cost and how they came to the figure that has been quoted (negative 32 cents a pound). I want to use similar rationale/calcs against the new RE.

Does anyone know where in the PFS or other doc's they came up with neg 32 cents with supporting rationale? I know it is widely quoted estimate (and I am not doubting it), I just want to see how the estimate was created.
