The cost of mining copper in Chile

From this month's AreaMinera comes this chart:

The ICCU index is a pretty carefully constructed dataset compiled by local beancounter firm Xlibrium that tracks the input costs for copper production in Chile. With October's numbers now in, the ICCU indicates that it's 0.15% cheaper to produce copper now than it was at the start of 2011. We also note that it's about 40% more expensive to mine copper than it was in January 2009.
