Change in capex: Another factor has been change in the sector’s Change in the sector’s C2C and mineral prices, 2007–13 level of capex, with companies accelerating investments to grow 150 60 capacity and improve infrastructure. For the mining companies 140 in our survey, overall capex jumped from 13% of sales (or US$67 billion) in 2007 to 22% in 2012 (US$156 billion). This 130 proportion then fell back to 19% (US$134 billion) in 2013 as 120 50 the sector sought to contain costs and focus on those projects x110 s providing the best returns.

The more the pain, the more urgency to gain. Changes in capex programs (with some choosing to be more selective) will be another contributory factor.
