OPEN PIT COSTS
•
Open pit unit costs of $4.98 per tonne mined in the third quarter. Strong result due to
improved mining rates, continuing refinement of the despatch system and shorter haul
sequencing.
•
2014 full year open pit unit mining costs expected to be below $5.30 per tonne mined.
•
Mine planning process underway, including analysis of stockpile management and
demobilisation schedule, including review of cost base.
Unit cost and expense drivers
Open pit movement to reduce by ~75% by 2017, driving lower gross expenditure
15% of 2014 expenditure increasing to 30% of annual expenditure to 2017
