Gold Fields Production Expected to Increase by Between 5% and 6% in December Quarter JOHANNESBURG, November 18 /PRNewswire-FirstCall/ -- Shareholders of Gold Fields Limited (JSE:GFI)(NYSE:GFI) are advised that production for the December 2004 quarter (Q2 F2005) is expected to increase by between 5% and 6% over that reported in the September 2004 quarter (Q1 F2005), with the South African operations expected to improve by approximately 3%. Rand per kilogram unit costs are expected to improve by approximately 2%, and total rand per ton costs by more than 5%, on a group-wide basis, despite continuing inflation pressures. The Group margin is expected to increase from 17% to between 20%-23% while the margin for the South African operations is expected to be restored to double digits. These expected improvement are largely due to the flow-through of benefits from sustainable revenue enhancement and cost reduction projects implemented specifically at Gold Fields' South African operations over the past year. Commenting on the improved operating performance expected for the December quarter, Ian Cockerill, Chief Executive Officer of Gold Fields said, "The performance from our South African operations has been excellent . We are now benefiting from the positive effects of the strategic repositioning of our high quality South African assets over the past year.
