peak copper

Have you guys seen the price of copper lately. It is trending up hard with supplies falling. I would not be surprised if it goes through $4 a pound. I wonder how that affects the NPV of Maun.

I have read different articles that all the known resources of different metals will be exhausted in the next 10 to 15 years. Similar to peak oil, the demand for base metals like copper will exceed supply and the price will increase astronomically. Of course increased prices will spark investment on exploration.
