White Nile Limited 30 May 2007 White Nile Ltd / Ticker: WNL / Index: AIM / Sector: Oil & Gas 30th May 2007 White Nile Ltd ('White Nile' or 'the Company') Southern Sudan Update White Nile Ltd, the AIM listed oil and gas exploration company, is awaiting official notification from the Government of Southern Sudan as to the conclusion of negotiations taking place in Khartoum, between representatives of the governments of Northern and Southern Sudan in regards to oil exploration and production issues in Southern Sudan. These encompass all oil licence areas in Southern Sudan including Block Ba, where White Nile has its rights granted by the Government of Southern Sudan. White Nile has received early indications that the discussions will establish clarity of title for Block Ba and the Company will update its shareholders when official clarification has been obtained. The Company is also pleased to announce an update on its drilling programme in Southern Sudan. Its first exploration well, Kedelai-1, situated in Block Ba 200 km north of Juba in the Jonglei State of Southern Sudan, spudded on 19 April 2007. With the onset of the rainy season, activity on the drill site as planned has been temporarily suspended, with the well at a total depth of 2,408m. The rig is being cold stacked on the well location and drilling will be resumed at the beginning of the next dry season - Q4 2007. Following resumption of drilling, the Company plans to extend Kedelai-1 to approximately 3,000m to evaluate reservoir objectives in the Aradeiba and Bentiu formations. White Nile is also preparing additional drilling locations on two further prospects identified through its initial seismic programme in the Jonglei State. This is where the Company believes the Muglad Basin, which is productive at Thar Jath, Mala, Heglig and Unity to the northwest of Block Ba, extends into the concession area. Furthermore, the Company is currently concluding plans to perform a 2D seismic survey in the Pibor Post basin in the eastern part of Block Ba approximately 200 km to the east of the the current drilling operations. Seismic shooting will begin at the beginning of the next dry season. * * E N D S * * For further information please visit or contact: Phil Edmonds White Nile Ltd Tel: 0845 108 6060 Jonathan Wright Seymour Pierce Ltd Tel: 020 7107 8000 Hugo de Salis St Brides Media & Finance Ltd Tel: 020 7242 4477 This information is provided by RNS The company news service from the London Stock Exchange
