with the constraint of only 90% of power, with some contribution from the seasonal decline due to the
Christmas break.
Steady state sustainable production from the June 2008 quarter and onwards should decline by approximately
608kg to approximately 6,800kg per quarter at cash costs of approximately R102,150/kg compared to the
December 2007 quarter.
In total approximately 2,600 of Driefontein’s 18,500 employees (including contractors) may be affected.
Kloof Gold Mine: Nos.3 and 8 Shafts
At Kloof it is proposed that Kloof 8 shaft be mothballed and production terminated with a loss of approximately
300 kg of gold per quarter. Pumping infrastructure in the shaft would be maintained. Kloof 3 shaft would be
scaled back and production reduced by approximately 510 kg per quarter to 840 kg per quarter.
In the March 2008 quarter production from Kloof Gold Mine is likely to decline by 1,700kg to 5,450kg and total
cash costs is likely to increase from R91,029/kg to R115,200/kg. The bulk of this impact is attributable to the
week long power shut down during the quarter, followed by lower production with the constraint of only 90% of
power with some contribution from the seasonal decline due to the Christmas break.
Steady state sustainable production from the June 2008 Quarter and onwards should decline by approximately
1,270kg to approximately 5,910kg per quarter at cash costs of approximately R104,061/kg compared to the
December 2007 Quarter.
The mine has formally requested an additional 8MW from Eskom due to difficulties experienced in re-
establishing safe production levels. Additional electricity is required to operate a recently commissioned
refrigeration plant, a recently commissioned underground booster fan, and pumping requirements.
In total approximately 2,300 of Kloof’s 17,200 employees (including contractors) may be affected.
South Deep Gold Mine
Since acquiring South Deep in January 2007 the mine has not achieved the planned increased ore production
as proposed in the feasibility study compiled by the previous joint venture owners (the Joint Venture Feasibility
Study). The mine has produced on average 108,000 tons per month of ore from underground, which is 71% of
planned production, whilst incurring 105% of the full planned production costs.
A full strategic review of the existing mine plan has concluded that the current installed shaft infrastructure will
not support the feasibility scope of mining activity which includes ore reserve development and the build-up of
production to the envisaged 330,000 tonnes of ore per month. The South Deep Twin Shaft infrastructure is still
under construction and has inadequate installed refrigeration, ventilation, water pumping and ore handling
facilities.
The inability to reach previously planned levels of production has been compounded by recent structural
geological changes, specifically in the conventional mining areas of the Ventersdorp Contact Reef (VCR). The
conventional mining of the Ventersdorp Contact Reef (VCR) above 95-level intersected the Waterpan fault
some 12 months earlier than predicted and this loss of mining face, in addition to the stopping of the two other
VCR mining areas, which encountered poor ground and unsafe conditions, has resulted in no conventionally
mineable areas being available to mine. As a consequence, all conventional VCR mining has been stopped.
To ensure that South Deep is optimally developed for the long-term benefit of all stakeholders, and to correct
the constraints imposed by the incomplete shaft infrastructure and inadequate ore reserve development on the
future viability of the mine, it is proposed to restructure the mine to address these constraints. The delivery of
the capital infrastructure and the development of the ore body have to be the primary focus for the next 18
months.
During this period ore production will be constrained to between 80,000 and 100,000 tons per month (200,000
ounces of gold annualised) from only the mechanised trackless sections of the mine and, to a lesser extent,
from the mechanised mining of the “de-stress cut”.
The proposed restructuring is likely to affect 2,000 of the 6,000 people (including contractors) employed at the
South Deep Gold Mine.
