Ann: Ore Supply Agreement with Glencore, page-87

I think it's all those saying that Glencore needed CDU more than CDU needed Glencore. In other words, sb1, WW etc - good onya sb1.

From Glencore's preso, not behind a paywall:

EHM – unit cost performance and project upside Current performance in line with expectations

Early ramp up to 6.0Mt planned for 2015, 12 months ahead of schedule

Mining unit costs reduced by 50%

42% reduction in EHM C1 Unit costs by end of 2015, taking operation from 4th Quartile to 2nd Quartile

Upside emerging

• Cave productivity already above nameplate capacity of 6.0Mtpa
• Ability to enhance grade (by up to 5%) due to Cave draw flow predictability
• Low rate milling strategy delivering higher than expected recoveries
• Leveraging Mount Isa expertise and productivity agenda

Also planning on extending mine life until 2030.
