Tarkwa Gold Mine heap leach facilities resume operations

Friday, 10 August 2012

Johannesburg, 10 August 2012: Further to our statement on 26 July 2012, Gold Fields Limited (Gold Fields) (JSE, NYSE, NASDAQ Dubai: GFI) is pleased to announce that the Environmental Protection Agency (EPA) of Ghana on 9 August 2012 lifted the temporary suspension on Tarkwa Gold Mine's (Tarkwa) heap leach facilities.

Tarkwa reopened both the North and South Heap Leach facilities on the evening of 9 August 2012 after they were closed on 16 July 2012 to comply with an EPA directive that water discharges should be passed through a water treatment plant to reduce conductivity levels (a measure of the amount of dissolved salts in discharged water).

Although Gold Fields believes that Tarkwa was complying with the prescribed conductivity levels in its water discharges, it has nonetheless commissioned the construction of two water treatment plants at the heap leach facilities. This is in pursuit of environmental best practice and in compliance with the directive. The plants are expected to be operational before the end of 2012.

In the meantime, as agreed with the Ghana Ministry of Environment, Science & Technology and the EPA, Tarkwa will continue to dilute and discharge excess water in a controlled manner while the plants are being built. Tarkwa will also submit monthly progress reports on the construction of the plants to the EPA.

The estimated impact on gold production as a result of the temporary closure is around 15,000 ounces, which is less than 10% of the mine's quarterly production. Tarkwa's Carbon-in-Leach plant, which produces about 75% of the gold at the mine, was not affected.
