Anglo Gold half year numbers

Looking at SENS this morning we had Anglogold Ashanti Limited - Report For The Quarter And Six Months Ended 30 June 2015. The numbers look solid enough given the tough environment for gold and gold producers. The shares are up 7.8% at the moment. The company unfortunately still made a loss given high interest costs but on an adjusted basis made a small profit. The other good news is that they brought their all-in costs down from $/oz 1 155 to $/oz 1021. If all the different costs reported confuses you as much as me, here is how they are calculated - Gold companies' cash costs and all-in sustaining cash costs.
