Review of South African Operations

		During financial 2010 Driefontein produced 709,800 ounces of gold at a cash cost of R168,568 per kilogram (US$692 per ounce) and an NCE of R225,208 per kilogram (US$924 per ounce). During the next 12 months to end-June 2011 the outlook for Driefontein is to produce between 707,300 and 771,600 ounces of gold at a cash cost of between R170,000 and R185,000 per kilogram and an NCE of between R217,000 and R230,000 per kilogram.

The Driefontein Gold Mine, which is located 70 kilometers west of Johannesburg, near Carletonville in the Gauteng province of South Africa, has produced more than 100 million ounces of gold during its 50-year life. Despite its prolific production history, this mine still has 52.0 million ounces of gold Mineral Resources, which includes approximately 17.2 million ounces of Mineral Reserves. Driefontein is a large, well-established deep to ultra-deep-level gold mine with its lowest working level some 3,400 meters below surface. Geologically the Driefontein Gold Mine is located on the north western rim of the famous Witwatersrand Basin, one of the greatest gold regions of the world. Three primary reefs are exploited; the Ventersdorp Contact Reef (VCR) located at the top of the Central Rand Group; the Carbon Leader Reef (CL) near the base; and the Middelvlei Reef (MR), which stratigraphically occurs some 50 to 75 meters above the CL. The mine comprises eight producing shaft systems, that mine different contributions from pillars and open ground, and three gold plants of which one plant processes mainly underground ore, with the remaining two processing surface material.

		During financial 2010 Kloof produced 566,500 ounces of gold at a cash cost of R187,154 per kilogram (US$768 per ounce) and an NCE of R256,962 per kilogram (US$1,054 per ounce). During the year to June 2011 the outlook for Kloof is to produce between 578,700 and 643,000 ounces of gold at a cash cost of between R180,000 and R195,000 per kilogram and an NCE of between R233,000 and R250,000 per kilogram.

The Kloof Gold Mine, which is located 60 kilometers west of Johannesburg, near Westonaria in the Gauteng province of South Africa, has produced more than 70 million ounces of gold during its 75-year life and was, in its heyday, known as the richest gold mine in the world. While this mine is now in the late summer of its life, it still has a massive 77.9 million ounces of gold Mineral Resources, of which 9.5 million ounces are in Mineral Reserves. A significant opportunity for Kloof is to increase mining flexibility through the development of reserves, and thus extend the life of this mine. Like Driefontein, its neighbouring sister mine, Kloof is a large, well-established intermediate to ultra-deep-level gold mine with its lowest working level some 3,350 meters below surface. Geologically Kloof is located on the main north-western rim of the Witwatersrand Basin and exploits auriferous palaeoplacers (reefs), namely the Ventersdorp Contact Reef (VCR) that constitutes 85 per cent of the underground Mineral Reserve ounces, the Middelvlei Reef (MR), 11 per cent, and two per cent from the Kloof Reef (KR). Kloof consists of five producing shaft systems and two gold plants of which 1 Plant processes surface material while 2 Plant process underground ore.
