Oromin Explorations Ltd.: Additional Drilling Results from Sabodala

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - May 24, 2006) - Oromin Explorations Ltd. (TSX VENTURE:OLE)(PINK SHEETS:OLEPF) -

HIGHLIGHTS

- LATERAL AND DEPTH CONTINUITY CONFIRMED AT GOLOUMA SOUTH ZONE

- GOLOUMA SOUTH TRENCH RESULTS INCLUDE 35.29 G/T GOLD OVER 9 METRES

- GOLOUMA SOUTH DRILL RESULTS INCLUDE 6.64 G/T GOLD OVER 23 METRES

- INITIAL MASATO DRILLING RESULTS INCLUDE 1.83 G/T GOLD OVER 39 METRES AND 7.46 G/T GOLD OVER 9 METRES

Oromin Explorations Ltd. is pleased to report the results from an additional seven drill holes on its Sabodala Property in eastern Senegal. Oromin has now completed nineteen drill holes at the target areas selected for the initial drilling evaluation and has results for twelve drill holes, five of which have previously been announced. The attached map shows the general location of these drill holes.

The target areas evaluated by these initial nineteen drill holes are the Niakafiri South area, the Masato area and the three zones within the broad Golouma gold geochemical anomaly. Results are pending for three additional holes at the Golouma South Zone and four holes recently completed at the Golouma West Zone, where drilling continues. Oromin's consulting geologists noted the presence of visible gold during the logging of the core from two of these pending holes at Golouma South (DH-14 and DH-15) and two of the pending holes from Golouma West (DH-16 and DH-17).

Trenching and drilling results from the Golouma South Zone have now confirmed gold mineralization along a minimum strike extent of 200 metres, within a NE-SW trending soil anomaly traceable for over 2,000 metres within the much broader Golouma anomaly. Positive drilling results from the three drill hole section (DH-03, 11 and 12) display excellent correlation to a minimum vertical depth of 100 metres. Results are pending for three additional step-out drill holes (DH-13, 14 and 15) completed both to the northeast and southwest of the reported drill hole results. Visible gold has been observed in core from holes DH-14 and DH-15.

The Masato target area has been extended from 1,500 metres to more than 2,000 metres in extent. The centre of the 2,000 metre by 300 metre North-South trending Masato soil anomaly is located six kilometres north of the minimum 3,000 metre by 1,500 metre Golouma soil anomaly. Previous work by BRGM (Geologic Branch of the French Government) at the Masato target area included eleven shallow, widely spaced drill holes over a 700 metre strike extent of which only seven holes intersected mineralisation returning a weighted average of 2.8 g/t gold over 15.9 metres. Oromin's initial drilling evaluation at Masato included re-drilling in the immediate area of two previous drill holes with DH-7 and DH-9, and adding two down-dip step-out holes, DH-8 and DH-10. Oromin's drilling results confirmed the previous operators' results and additionally expanded the mineralization on both drill sections to depth. Oromin's two completed drill sections are 500 metres apart within the centre of the 2,000 metre soil anomaly. Drill road preparation has begun at the Masato area to enable a tightly spaced, grid-based definition drilling evaluation throughout the upcoming rainy season.

Oromin's coincident geochemical-geophysical Niakafiri South target has been expanded by 225% and can now be traced for more than 4.5 kilometres south from the Oromin/Mineral Deposits Limited ("MDL") concession boundary and remains open to the south and west. Trenching has been completed over only the northernmost 1,000 metres of this 4.5 kilometre extent. The trench results include 1.06 g/t gold over 14.0 metres, 1.28 g/t gold over 15.0 metres, 1.73 g/t gold over 10.0 metres and 1.82 g/t gold over 11.0 metres. Oromin's trench results are similar to the initial results reported in 1987 by BRGM (Geologic Branch of the French Government) at the Niakafiri deposit on MDL's adjacent concession. The Niakafiri South mineralised zone is believed to be the immediate southern extension of MDL's Niakafiri deposit.

The southern most drilling completed by MDL on its Niakafiri deposit is approximately 200 metres north of the Oromin/MDL concession boundary. Oromin drill hole DH-06 was collared 60 metres to the northeast and on-trend with previously released hole DH-05 (collared 400 metres south of the Oromin/MDL concession boundary) and intersected similar style and grade of mineralization as many of the MDL drill holes at the adjacent Niakafiri deposit.

The results from Oromin's first two drill holes at Niakafiri South display excellent correlation of a 30 metre wide mineralised zone to a minimum depth of 125 metres. Oromin plans to undertake extensive grid-based drilling over the entirety of the current 4,500 metre strike extent of the Niakafiri South target area. The majority of this drilling will be carried out during the upcoming rainy season.

New Targets

Ongoing programs of detailed mapping, sampling, geophysics and trenching at the numerous new targets throughout the 230 square kilometre Sabodala exploration concession continue to provide encouraging results in preparation for drilling of these new targets.
