Oromin Explorations Ltd.: Excellent Drilling Results Continue at Sabodala, Six Drills Increase Pace of 140,000 Metre 2008 Resource Drilling Program

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 5, 2008) - Oromin Explorations Ltd. (TSX VENTURE:OLE)(OTCBB:OLEPF) -

HIGHLIGHTS

- LATEST DRILLING RESULTS CONTINUE TO EXPAND MINERALIZATION AT GOLOUMA SOUTH, GOLOUMA WEST AND MASATO INCLUDING:

- 5 metres of 12.62 g/t gold in RC-265 at Golouma South

- 6 metres of 13.08 g/t gold in RC-268 at Golouma South

- 9 metres of 6.58 g/t gold in RC-240 at Golouma West

- 11 metres of 8.15 g/t gold in RC-241 at Golouma West

- 20 metres of 3.30 g/t gold in RC-208 at Masato

- 10 metres of 5.83 g/t gold in RC-232 at Masato

- INITIAL NI 43-101 COMPLIANT MINERAL RESOURCE ESTIMATE BY SRK SCHEDULED FOR END OF MAY

Oromin Explorations Ltd. ("Oromin") is pleased to announce additional results from the ongoing step-out and in-fill drilling program at the Golouma West, Golouma South and Masato Gold Deposits. SRK Consulting (Canada) Inc. are undertaking a NI 43-101 compliant inferred mineral resource estimate for these three deposits scheduled for completion at the end of May.

Currently, six drill rigs are involved in the aggressive drilling activities at Sabodala to accelerate the pace of Oromin's 140,000 metre 2008 drilling program focused on resource definition and delineation of Sabodala Exploration concession's numerous gold zones and deposits. Drilling will be directed at both known and newly outlined gold deposits at depth and along trend, as well as initial evaluation of all remaining significant targets established within the concession. Results from the ongoing property-wide exploration program continue to support Oromin's model of multiple gold deposits within the Sabodala Exploration Licence.

GOLOUMA SOUTH GOLD DEPOSIT

The Golouma South gold deposit is centred within a 3-kilometre northeast trending gold geochemical anomaly that flanks the southeast side of the extensive Golouma gold geochemical complex of anomalies.

Our reverse circulation and diamond core drilling results continue to expand mineralization, now successfully drilled over a 1,065 metre strike extent, which ranges from the southernmost hole RC-265, which returned 12.62 g/t gold over 5 metres, to the Golouma Northeast portion of the deposit where RC-268 returned 7.40 g/t gold over 5 metres and 13.08 g/t gold over 6 metres. Resource drilling at 40 and 20-metre centres has concentrated along 450 metres of the "main zone" area located between 3+75S and 0+75N. Some of the most significant new results at Golouma South include:

RC-268 159 5 7.40
and 167 6 13.08
RC-236EXT 245 4 5.58


GOLOUMA WEST GOLD DEPOSIT

The Golouma West Gold Deposit has now been traced over 1,500 metres on surface, to over 300 metres at depth and remains open in all directions. Oromin is drilling this deposit on 40-metre, and locally 20-metre centres using both reverse circulation and diamond core rigs.

The results continue to expand mineralization. Grade and thickness correlations continue to be excellent both along strike as well as to depth, as exemplified by RC-228 which returned a 13-metre interval grading 3.25 g/t gold contained within a much broader mineralized interval of 1.91 g/t gold over 35 metres from 269-304 metres. These results compare favourably with previously released core holes, DH-169 (3.49 g/t gold over 13 metres from 277-290 metres), DH-180 (4.97 g/t gold over 6 metres from 245-251 metres and 1.65 g/t gold over 16 metres from 270-286 metres) and DH-181 (2.26 g/t gold over 16 metres from 306-322 metres). DH-169, 180 and 181 are the deepest holes for which results are available in the central portion of the deposit. An additional tier of deeper holes is now underway to test the down-dip and down-plunge extension to these encouraging results. Some of the most significant new results at Golouma West include:

and 157 5 28.39
RC-228EXT 269 13 3.25


MASATO GOLD DEPOSIT

The Masato Gold Deposit is defined by a strong gold-in-soil geochemical anomaly 2.6 kilometres in length by up to 1.2 kilometres in width and by surface trenching. It is located 1.2 kilometres due east of MDL's gold deposit (2.01 million ounces of measured and indicated resources at 2.2 g/t gold) that is being readied for production in the fourth quarter of 2008 (See MDL's April 18, 2008 news release).

The Masato deposit trends northeast and dips moderately steeply to the west. It is currently being shallow drilled (up to -200 metre depth) on 40-metre and locally 20-metre centres over a 1.42 kilometre strike extent - as defined by new drill holes RC-208 and 209 on line 3+00S and DH-279 and 280 on line 11+20N - and remains open in both directions.

Some of the most significant new results at Masato include:

OTHER GOLD TARGETS

In addition to the Niakafiri Southwest target, other significant gold targets to be drill-tested during 2008 include the following, each of which returned excellent initial trench results which are similar to the initial trench results at Golouma prior to Oromin's early drilling success there.
