Oromin Negotiates Exploration Extension at Sabodala

2007 Exploration Program to Focus on Resource Drilling of Gold Zones Greater Than 75,000 Metres of Drilling in 450 Holes Planned for 2007

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 21, 2007) - Oromin Explorations Ltd. (TSX VENTURE:OLE)(OTCBB:OLEPF) is pleased to announce that the Government of Senegal has granted the Oromin Joint Venture Group Ltd. ("OJVG") a 20 month extension (to December 22, 2008) to the current Sabodala Mining Convention, following which OJVG has 10 months (October 22, 2009) to complete a preliminary feasibility study on the project.

As a result of the very successful exploration program carried out during the original 22 month exploration phase, Oromin applied on behalf of OJVG for additional time to further explore the numerous gold deposits identified or advanced during the initial period. Oromin and its joint venture partners spent well in excess of the USD$8 million required by the original Mining Convention, spending approximately US$11 million by December 30, 2006 and carrying out extensive property wide exploration including drilling 10,500 metres in 70 holes. During the 20 month extension, OJVG is required to spend a minimum of USD$12 million in exploration.

OJVG's ongoing exploration program for 2007 will include a minimum of 75,000 metres of core and reverse circulation drilling in approximately 450 holes, as well as 20,000 metres of excavator trenching. The budget for this program is expected to exceed the USD$12 million required during the extension period. OJVG intends to begin the initial resource calculation for Sabodala by year end.

Along with the grant of the extension, the title to the Sabodala exploration concession has been officially transferred to OJVG, a private joint venture company owned by the same parties to the unincorporated joint venture on behalf of which Oromin held the concession, namely Oromin and Bendon International Ltd. ("Bendon") each as to 43.5% and Badr Investment & Finance Company ("Badr") as to a 13% carried interest. Oromin and Bendon have agreed to fund equally all expenditures on the Sabodala property. Oromin remains as operator of Sabodala to manage exploration on behalf of OJVG.

Since initiation of exploration, many gold discoveries have been identified by Oromin at Sabodala including: Golouma West, Golouma South, Golouma Northeast, Golouma Northwest, Niakafiri South, Masato and Maki Medina as well as numerous other exploration targets throughout the 230 square kilometer concession. Drilling has been ongoing since early 2006 at a variety of target areas including current core drilling at Maki Medina, Masato North, Golouma South and Golouma Northeast as well as detailed 40-metre spaced reverse circulation drilling at Golouma West and Golouma South. Please refer to Oromin's website for location maps and complete listing of results.

Oromin has initiated an extensive reverse circulation drilling program (40-metre centres) across the entirety of the known area of mineralization over a minimum strike extent of 750 metres. Mineralization has been intersected to depths beyond 150 metres and remains open. In addition, many of the drill holes intersect parallel zones of gold mineralization. Considerable additional drilling is planned at Golouma West.
