Oromin Explorations Ltd.: Encouraging Preliminary Results from Sabodala

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 8, 2005) - Oromin Explorations Ltd. (TSX VENTURE:OLE) is pleased to report on the successful progress of the ongoing first phase of the USD$8 million comprehensive exploration program at its 230 square kilometre Sabodala Property in eastern Senegal.

Sabodala - Senegal

Oromin's three field geologists have begun trenching at three areas within a 300-metre extent of the Golouma area, where previous limited sampling carried out by Henry J. Awmack P. Eng., the Company's consulting geologist, returned 15.8 g/t gold over a 2.3 metre width of altered, sheared wallrock adjacent to a 0.8 metre quartz vein grading 0.25 g/t gold. Historical trenching results obtained by BRGM (Geologic Branch of the French Government) from this area include: 3.4 g/t gold over 4 metres, 5.4 g/t gold over 5.5 metres and 11.4 g/t gold over 6.5 metres, with none of these trenches exposing the full width of mineralization present. The current trenching has exposed a much greater width of the sheared, altered host unit, in addition to abundant quartz stockwork and quartz veining. The trenching activities have uncovered occurrences of fine visible gold at two of the three trench locations, both within the veining and altered host rock.

Fugro Airborne Surveys has completed the 6,242 line kilometre airborne geophysical survey over the entire Sabodala Property. Excellent quality data was obtained from the ultra-high resolution MIDAS™ II helicopter-borne magnetic and radiometric system flown at 50-metre line separation and terrain clearance of 15-25 metres. Oromin is awaiting receipt of final map products, but is very encouraged by the detail and quality of the preliminary data provided.

More than 75 line-kilometres of GPS-controlled grid were cut in preparation for ground geophysics, soil geochemistry and geologic mapping. Oromin's ground geophysical program (Induced Polarization and Magnetics) has been completed over approximately 50-line kilometres thus far. Preliminary field data from the Induced Polarization geophysics suggests that at least two areas display excellent line-to-line correlation for chargeability responses over considerable width and extent. Soil geochemical sampling and geologic mapping has been completed over the majority of the grid covering Oromin's current priority exploration target areas of Golouma, Kerekounda and the South Sabodala-Maka Madina trend.

All fieldwork was carried out under the supervision of G. McArthur, P.Geo. and Douglas Turnbull, P. Geo, has reviewed the data presented in this news release.

Carneirinho - Brazil

Oromin is also pleased to announce that its independent consulting geologist has completed his evaluation visit at the Carneirinho Property in the Tapajos region in Brazil. Results from this review, in preparation for a 43-101 report, confirm previous exploration activities and results reported by TVX Gold Inc. The Carneirinho Property is held under option jointly by Oromin and Lund Gold Ltd.

Santa Rosa - Argentina

Further to its news release of December 9, 2004, Oromin reports that Surge Global Energy, Inc. ("Surge") has elected to maintain its interest in Oromin's Santa Rosa oil and gas prospect in Argentina at 17.52%. The purchase price for Surge's interest was USD$600,000. In addition, Irie Isle Limited, Oromin's wholly-owned BVI subsidiary, received 1,000,000 shares of Surge as consideration for the various extensions of the purchase agreement.

Subject to financing, Oromin and Surge will jointly undertake the next phase of the exploration program, at an estimated cost of US$1,350,000, which will consist of interpretation of seismic data, completion of environmental studies, drilling three exploration wells and, contingent upon success, completing one production well. All required funding for the upcoming phase of exploration and all future exploration and development of the Santa Rosa property will be borne by each party in proportion to its interest in the Santa Rosa Property.
