Oromin Explorations Ltd. ("Oromin"), on behalf of the Oromin Joint Venture Group ("OJVG"), is pleased to announce additional results from the ongoing step-out and in-fill drilling program at its Sabodala Gold Project in eastern Senegal. The majority of 2009 drilling to date has focused on the lateral and vertical expansion to the high-grade Kerekounda gold deposit, as well as resource expansion drilling at each of the Golouma West, Golouma South and Masato gold deposits.

NEW DISCOVERY

Oromin is systematically examining numerous new targets on the project, based on geological, geochemical and geophysical criteria. One of these new targets is located 1 km south of the recently discovered Kerekounda deposit, in the vicinity of Golouma Northeast, where previous results include: 98.37 g/t gold over 3 metres in DH-72 and 17.61 g/t gold over 8 metres in DH-73. This New Discovery has successfully been intersected by two drill holes on the same drill Section, with a down-dip separation of approximately 100 metres, as outlined in the following table:

Mineralized intervals are based on 1-metre composite samples utilizing a
0.5 g/t gold cut-off level with a maximum internal dilution of 2 metres.
No cutting of gold assays has been employed for reported intervals. The
attitude of mineralized intervals varies and reported mineralized
intersections may not represent true widths.
KEREKOUNDA DEPOSIT

As the following table indicates, favourable widths and high-grade results continue at the Kerekounda gold deposit, a continuous shear-hosted vein system for which significant results are now available over a minimum 300-metre strike extent and a minimum down-dip extent of 300 metres, as established by DH-426, DH-427 and DH-428. Current drilling is systematically stepping out to test the down-dip extent beneath certain deeper intersections, including the previously released 10.12 g/t gold over 13 metres in DH-426. Kerekounda remains open to expansion both laterally and to depth. Oromin management continues to be encouraged by this early-stage drilling success at Kerekounda. Based on the present geometry, continuity and high-grade nature of results received to-date, Oromin views Kerekounda as an attractive, early-stage combined open pit and underground mining opportunity that will enhance and complement previously announced preliminary resources at the Masato, Golouma west and Golouma South gold deposits.

The following table outlines the significant drilling results recently received from Kerekounda:

Outlook

Oromin's further and ongoing 2009 drilling plans include an aggressive evaluation to expand the high-grade Kerekounda gold deposit, to outline and define oxide mineralization potential at various other known gold deposits, and to continue the systematic evaluation of other structural-geochemical targets throughout the Golouma-Kerekounda region.

Our 2009 Pre-Feasibility Study being undertaken by SRK Consulting is proceeding on schedule with metallurgical, hydrological, geotechnical, resource evaluation, infrastructure/site development, social and environmental programs under way and ongoing.
