Please check the numbers for December again as there are a bit confusing. The cost rage 1360-1390 refers to the final all-in cash cost for the full year.
"Final all-sustaining costs will be reported as part of the Company’s December 2017 Quarterly Report, due for release later this month. However, costs are expected to remain in line with the previously published guidance range of A$1360-1390/oz for CY2017."
There guidance for the cost for the December Quarter was in the range of 1200-1250 (see September Quarterly Actitivies Report). So if they expect to meet the cost for the full year guidance, they should have met the cost guidance for the December Quarter.
