Gold Fields Limited and Gold One International Limited to Investigate a Joint Venture for Retreatment of West Rand Surface Tailings Deposits

JOHANNESBURG, January 24, 2012 /PRNewswire/ -- Gold Fields Limited ('Gold Fields') and Gold One International Limited are pleased to announce that they have entered into a Memorandum of Understanding ('MOU') to investigate the viability of concurrently reprocessing their combined surface tailings deposits, located on the West Rand region of South Africa's Witwatersrand Basin. Gold One and Gold Fields currently operate mines on the West Rand, a region with a long history of gold and uranium mining.

In terms of the MOU, Gold Fields and Gold One (collectively, the 'parties') will jointly investigate the feasibility of establishing a Joint Venture into which both parties will contribute surface assets for retreatment. These assets are expected to comprise in excess of 700 million tonnes and represent over 60% of the total tailings material in the region. The parties aim to complete a detailed scoping study by the middle of this year, following which a decision will be taken on whether to progress the study to a feasibility level.

Should the Joint Venture proceed, the intention is to reclaim and retreat the historical tailings material and current tailings to recover residual gold, uranium and sulphur. A key objective of the project will be to address the re-deposition of the residues in accordance with modern sustainable deposition practices, ultimately supporting mine closure in an environmentally sustainable manner.

In 2010, Gold Fields completed extensive economic studies on its Tailings Treatment Project ('TTP'), which is a low-grade gold and uranium recovery project focusing on the existing tailings storage facilities and the current underground mining horizons of Gold Fields' West Rand operations, KloofDriefontein Complex ('KDC') and South Deep. As at December 2010, Gold Fields declared a mineral resource of 475.6 million tonnes at its tailings storage facilities, which includes gold mineral resources of 4.5 million ounces and uranium mineral resources of 53.6 million pounds.

Gold One advised Gold Fields that on 9 January, 2012, it completed the acquisition of Rand Uranium (Pty) Limited ('Rand Uranium'). Furthermore, as part of the Rand Uranium transaction, Gold One established the Randfontein Surface Operations, which are currently processing approximately 300,000 tonnes of tailings material per month through the Cooke Gold Plant. Gold One also advised that it had commenced with a review of its Cooke Uranium Project.

Rand Uranium had earlier completed a comprehensive definitive feasibility study on the processing of the Cooke Tailings Deposit for the extraction of both gold and uranium (including 70% of detailed and already completed engineering design). The primary focus of the feasibility study is the construction of a uranium metallurgical plant to treat the Cooke Tailings Deposit. In addition, during the December 2011 quarter, Gold One stated that it commenced assessing the potential treatment of several other surface tailings deposits that exist on the mining and prospecting licenses acquired from Rand Uranium.

The combined consideration of the Gold One, Rand Uranium and Gold Fields studies, as well as the possibility of utilising existing and planned metallurgical plant infrastructure, will allow the companies to significantly fast-track a joint economic assessment of the reprocessing of the combined tailings deposits.

Gold One President and Chief Executive Officer Neal Froneman comments: 'I am excited about the opportunity of forging a strategic relationship with Gold Fields. Economic recovery of gold and uranium from historical tailings deposits has been successfully demonstrated in other districts of the Witwatersrand Goldfields. The combination of our extensive technical studies and the quality of assets that would be pooled into the partnership presents an exciting prospect for the Joint Venture and growth of Gold One's surface business. Importantly, the economically sustainable retreatment of the existing tailings deposits will also have a positive environmental impact, benefiting all stakeholders in the district in which we operate.'

Gold Fields Chief Executive Officer Nick Holland comments: 'This is an exciting opportunity to investigate the feasibility of extracting value from our substantial surface resources on the West Rand. Gold Fields already has projects in place to retreat our tailings and the MOU with Gold One allows us to further explore a relatively low risk opportunity to extract value from Gold Fields' surface resources that is not inherent in our share price.'
