The Virginia operations, situated in the Free State province, are among the oldest in the group and at year-end comprised Unisel and Merriespruit 1. Ore from Unisel is processed at Harmony 1 plant, while that from Merriespruit 1 is treated at Central Plant. These operations, which are of intermediate depth, ranging from 1 000 to 2 000 metres, employ scattered mining and pillar reclamation to access the Basal, Leader, Middle and A reefs.
Virginia employed 4 036 in FY10, of which 3 979 were employees and 57 contractors. This will decrease to approximately 2 500 people in FY11.
Detailed information on Virginia’s resources and reserves are available in the Mineral resources and mineral reserves section of this annual report.
There were most regrettably five fatalities at the Virginia operations in FY10 as compared with one the previous year. Following a significant improvement in FY09, there was a slight deterioration in the LTIFR to 12.86 per million hours worked in FY10 (FY09: 12.38).

Following a review of Harmony’s asset portfolio and the economic viability of the Virginia operations, and given the depletion of their orebodies, mature infrastructure and low grades, production ceased at Brand 3, which has been placed on care and maintenance, and at Harmony 2 and Merriespruit 3. To enable certain sections of Merriespruit 1 to continue operating, a job preservation and profitability agreement was signed with organised labour. As a result of the restructuring of the Virginia operations, production for the year was down 27% to 1.7Mt milled. Together with a 10% decline in grade, this resulted in gold production of 170 013 ounces, a decrease of 34%.
The development at Merriespruit 1 focused on those areas with the best short-term grade potential and better grades are expected as a result. At Unisel, Basal Reef development produced good results while Leader Reef development was negatively affected by poor environmental conditions which will be addressed by the cooling project. Middle Reef development focused on the decline area in pillars and was negatively affected by reef pinch outs and reef variability. B Reef development was undertaken in a fault block which made access easy but results were poor and development was halted. Overall, the shaft produced reserves on the Basal and Leader reefs. Future development will focus more on the better grade E block.
Revenue of R1 415 million was down by 30%, which combined with an increase in cash operating cost of 37% to R252 537/kg (US$1 036/oz), resulted in operating profit declining by 86% to R75 million (US$10 million). Capital expenditure of R180 million (US$24 million) was spent largely on on-going development (72%) and on maintenance and other shaft capital (28%).
In FY11, volumes mined are expected to be around 1.1Mt at a grade of 3.75 g/t. Gold production is expected to be 4 212 kilograms (135 419 ounces), while cash costs** are forecast to be approximately R224 000/kg (US$ 913/oz). This forecast is highly dependent on the success of mining and costs at Merriespruit 1.
A great deal of development is still required to access the Basal Reef at Unisel, and the high-grade shaft pillar will be exploited at the end of its life-of-mine.
Capital expenditure** of R78 million (US$10 million) is planned for FY11 – R57 million (US$7 million) on on-going development and R21 million (US$3 million) on major equipment maintenance and other shaft capital.
Current productivity levels of 84g/TEC are forecast to improve to an annual average of 140g/TEC during peak production.
