This is interesting,

"We believe that copper price will have to approach US$10,000/t in the medium term to incentivise the next wave of mined copper growth."

Its from August 2013. Its 80+ pages but you can get by just reading pages 1-4, and if you are interested in the "geology of copper" then feel free to read pages 7-9 and "copper mining process" on pages 11-13. After that, there is significant analysis on the major copper mines.

Hope it is of interest to some.
