Here's another article on the future of copper supply. Imagine if that happens? Maybe we would be better off waiting until 2018 to sell.

"global research and investment management group Bernstein senior analyst, Paul Gait, looks to the medium- and long-term view and sees a massive copper supply deficit building over the next few years and reaching as much as 1.5 million tonnes by 2018.

And if China recovers a bit more steam over the period – it still lags major industrialised nation copper consumption per head by a huge amount, hence the comment that the so-called industrial super cycle, very much driven by China growth, is only one-third of the way through. There may be a temporary hiatus, but it will return as china continues to urbanise.
