big c, page-56

Hi alley,

I read the same comments. The difficulty I have in modelling this metric is that it is not reported widely and although it is an excellent cost metric, it does not allow modelling to go forward as it does not take into a/c by product credits.

As TB said, this metric is independent of factors that have a direct impact on mine profitability (by products and head grade), so I think it would make the model worse rather than better.

I am happy though to have more discussion about this.
