Awards Seismic Contract

White Nile Limited 17 June 2005 17th June 2005 White Nile Limited ('White Nile' or 'the Company') Awards Seismic Contract for Block Ba in South Sudan White Nile Ltd, the AIM listed oil & gas exploration company 50% owned by the ' New Government of South Sudan'*, is pleased to announce that Terra Seis Geophysical Ltd ('Terra Seis'), a wholly owned subsidiary of Terra Seis International, has been awarded the contract to conduct an extensive seismic evaluation programme of White Nile's 65,000 sq km Block Ba oil licence area in South Sudan. Following a competitive tender process, Calgary based Terra Seis has been commissioned to acquire 2,000 km of high resolution geophysical data focussed on a high definition seismic programme. The 10 month project, which will start immediately, will primarily focus on the areas within Block Ba thought to be highly prospective i.e. the extensions of the Melut and Muglad Basin areas. These Basins already have oil production to the north of the Block Ba concession area. Canadian registered Terra Seis, founded in 1999 by Kevin Plintz, specialises in implementing and managing seismic programmes across the world. It has worked extensively in Africa, the Middle East, Central and South America and most recently in Tanzania, Nigeria, Trinidad and Guatemala, carrying out seismic programmes for a broad range of international and national oil companies across a spread of terrains. James Jost, Managing Director of International Operations for Terra Seis will head the programme in South Sudan. White Nile is also studying the possibility of running further gravity surveys in parallel to the seismic programme. White Nile Chairman Phil Edmonds said: "As we said in the Admission Document, it is our intention to undertake an intensive exploration work programme with the aim of establishing new discoveries of oil and gas in South Sudan and thus generating revenues as soon as possible. To this end it was important that we commissioned an extensive seismic survey to develop Block Ba as soon as practicable. We have signed with Terrra Seis as its team offered us the most complete package ranging from their experience and enthusiasm to their reputation within the industry and their social policy. Importantly, Terra Seis have the personnel and equipment to commence work immediately which will hopefully result in drill targets being identified at the earliest opportunity." Terra Group of Companies Chairman Kevin Plintz said: "We are extremely excited to be working with White Nile in South Sudan. We believe that we have the experience and industry expertise to successfully carry out the seismic programme over the Block Ba licence area and to assist the Company in identifying potential drill targets as quickly as possible. The main areas of activity will be focussed on sectors of Block Ba which have been identified as being the extensions of the production fairways of the Melut and Muglad Basins. We are already organising the transportation of teams and equipment and expect the data acquisition process to be completed by June 2006. Importantly we have worked with a cross section of oil companies that have maintained our services due to the quality of our work as well as our strong social policy." * * E N D S * * Issued on behalf of White Nile Ltd by St Brides Media & Finance Ltd, 46 Bedford Row, London WC1R 4LR.
