Oromin Explorations Ltd.: Initial RC Drill Results Confirm and Expand Continuity of Golouma South Gold Mineralization

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Jan. 18, 2007) - Oromin Explorations Ltd. (TSX VENTURE:OLE)(OTCBB:OLEPF) -

HIGHLIGHTS

- STEP-OUT AND IN-FILL RC DRILLING CONFIRMS SIGNIFICANT GOLD INTERSECTIONS AT GOLOUMA SOUTH ZONE INCLUDING 24.58 G/T GOLD OVER 9 METRES, 11.90 G/T GOLD OVER 8 METRES AND 3.73 G/T GOLD OVER 15 METRES RESPECTIVELY.

- DIAMOND CORE DRILLING CONTINUING AT GOLOUMA NORTHEAST, WHERE VISIBLE GOLD INTERSECTED IN TWO HOLES AND AT MAKI MEDINA WHERE BROAD ALTERATION TO 25 METRES IN MULTIPLE ZONES INTERSECTED.

Oromin Explorations Ltd. is pleased to provide results for the initial 10 reverse circulation drill holes at its Sabodala Property in eastern Senegal. All ten holes were drilled at the Golouma South gold zone just prior to the Christmas break.

The following table outlines the significant results from the in fill and step-out reverse circulation drilling at Golouma South. Previous core drilling has returned results that included 23 metres at 6.64 g/t gold in hole DH-11, 17 metres at 7.06 g/t gold in DH-14, 9 metres at 9.70 g/t gold in DH-43 and 16 metres at 4.99 g/t gold in DH-61.

All RC drill holes assay intervals are based on one metre sample composites within the mineralized zone. The attitude of mineralized intervals varies and may not represent true widths.

These new drill results confirm and expand the lateral and depth continuity of gold mineralization previously identified at Golouma South by both excavator trenching and diamond core drilling. Combined trenching, core and RC drilling results have now intersected the Golouma South gold zone mineralization over a minimum 400-metre strike extent. The Golouma South gold zone remains open to expansion, especially to the south where RC-10, the southernmost hole completed to-date, intersected 9 metres at 24.58 g/t gold. RC drilling is continuing up-dip, down-dip and along trend to the south of Oromin hole RC-10 utilizing a 40-metre grid and drill hole spacing leading towards the undertaking of a future resource study.

Drilling re-started at Sabodala on January 11, 2007. Oromin is presently drilling with two core rigs and one reverse circulation rig and has sourced additional reverse circulation rigs that are expected to arrive at Sabodala in the first half of 2007. The two diamond core rigs are presently drilling at the recently discovered Golouma Northeast and Maki Medina zones and the reverse circulation drill rig is at Golouma South. The RC drill rigs will focus on 40 metre centre-drilling of known mineralized zones as a precursor to future resource calculations whereas the diamond core rigs will be used to broadly define the lateral and vertical extent of gold zones and deeper drilling requirements. Upcoming drilling will be directed at Niakafiri South, Masato, Golouma West as well as more recent discoveries at Sabodala North, Masato North, Sekoto and Kinemba.

Fieldwork was carried out under the supervision of Gerald McArthur P. Geol., a "qualified person" for the purposes of National Instrument 43-101, who has also verified the data disclosed in this news release. TSL Laboratories in Saskatoon, Saskatchewan carried out all assaying.
