Operational review

Overall, AQPSA recorded production of 222,000 ounces of platinum in FY2006, an increase of 38% on production of the previous financial year. The increase in production was largely attributable to record production at Kroondal and the coming onstream of production at Everest.

In particular, Kroondal delivered a solid performance during the year, producing 131,000 ounces of platinum-inconcentrate (including the P&SA). Problems were experienced with potholing at 3 shaft but these were overcome and production is now on track and the sinking of a decline at 5 shaft has begun. Steady state production at Kroondal is scheduled from September 2007.

Operating performance at Marikana remains a concern and was hampered by a contractor dispute and heavy rains in late summer. However, a new mining contractor has been appointed and is performing well. Production at Marikana was 35,000 ounces of platinum-in-concentrate. Pit mining continues to be problematic regarding both volumes and recoveries, however, the situation has been addressed and is improving. Development of the infrastructure for the trial underground mine is under way.

Good progress is being made at Everest and production of 56,000 ounces of platinum-in-concentrate in FY2006 was achieved, following the commissioning of the plant in December 2005. Concentrate is being delivered to IRS. Development at Everest began in October 2004 and the operation is well on schedule to produce around 140,000 ounces of platinum-in-concentrate in FY2007. The opencast mine is nearing the end of its life and the establishment of the underground mine is on target.

Aquarius’ contribution to net profit was significantly higher at R114 million in FY2006 compared with a R4 million loss in FY2005. Aquarius’ gross margin was also significantly higher.


Aquarius is expected to maintain its current levels of production and to continue making a positive contribution to Implats.
