EXCELLENT DRILL RESULTS AT GOLOUMA WEST, GOLOUMA SOUTH AND MASATO GOLD DEPOSITS ADD TO LATERAL AND DEPTH EXPANSION

Oromin Explorations Ltd. has released additional results from the continuing step-out and infill drilling program at the Golouma West, Golouma South and Masato gold deposits.

Highlights:


At Masato, DH-131 intersects a 20-metre mineralized zone including 3.22 grams per tonne gold over five metres, followed by 3,945 g/t gold over one metre (visible gold observed) and then 3.56 g/t gold over 14 metres.
At Golouma South, DH-150 intersects the deepest mineralization to date: 9.05 g/t gold over eight metres and 5.08 g/t gold over 19 metres.
At Golouma West, DH-156 intersects three mineralized zones: 45.03 g/t gold over five metres, 11.29 g/t gold over 10 metres and 7.77 g/t gold over seven metres.

Oromin's 2007 and 2008 advanced exploration programs are focused on resource delineation of its Sabodala gold project's numerous gold zones and gold deposits. More than 75,000 metres of drilling are planned in advance of the project's initial resource estimate scheduled for April, 2008. Results from the continuing propertywide exploration program continue to support Oromin's model of multiple gold deposits within the Sabodala project. Please refer to general maps displayed under investor info/articles and reports on Oromin's website and Oromin's previous news releases for additional project information.

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.

Newly drilled mineralized intersections are listed in the table, Golouma West gold deposit mineralization intersections; some of the most significant are:


12 metres of 8.74 g/t gold from 49 metres in DH-132;
Six metres of 10.08 g/t gold from 37 metres in DH-145;
Eight metres of 3.54 g/t gold from 57 metres in DH-147;
16 metres of 2.11 g/t gold from 301 metres in DH-149;
13 metres of 6.07 g/t gold from 82 metres in DH-152;
10 metres of 6.91 g/t gold from 128 metres in DH-154;
Five metres of 45.03 g/t gold from 17 metres, 10 metres of 11.29 g/t gold from 142 metres and seven metres of 7.77 g/t gold from 165 metres in DH-156;
Seven metres of 25.58 g/t gold from 138 metres in DH-157;
Seven metres of 13.41 g/t gold from 31 metres in DH-161;
Seven metres of 6.51 g/t gold from 71 metres in DH-163;
17 metres of 3.36 g/t gold from 166 metres in DH-165;
18 metres of 4.80 g/t gold from 238 metres in DH-168.

Golouma South gold deposit

The Golouma South gold deposit has now been traced over 1,000 metres on surface to 220 metres 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.

Newly drilled mineralized intersections are listed on the table, Golouma South gold deposit mineralization intersections; some of the most significant are:


Seven metres of 7.12 g/t gold from 44 metres in DH-138;
10 metres of 3.70 g/t gold from 15 metres in DH-140;
Eight metres of 9.08 g/t gold from 192 metres and 19 metres of 5.08 g/t gold from 229 metres in DH-150.

Masato gold deposit

The Masato gold deposit is coincident with a strong gold-in-soil geochemical anomaly 2.6 kilometres in length by up to 1.2 kilometres in width. Oromin's Masato gold deposit is located 1.2 kilometres due east of the 1.9-million-ounce Sabodala gold deposit that is being readied for production by Mineral Deposits Ltd. (see Mineral Deposits' Aug. 16, 2007, news release).

The Masato geochemical anomaly is also coincident with three extensive northeast-trending, linear induced polarization changeability anomalies, of which only the westernmost has been drilled to date. Oromin has recently initiated infill drilling at 40-metre centres over portions of this large mineralized zone using both reverse circulation and diamond core rigs.

Newly drilled mineralized intersections are listed in the table, Masato gold deposit mineralization intersections; some of the most significant are:


Five metres of 3.22 g/t gold from 58 metres, one metre of 3,945.50 g/t gold from 63 metres (visible gold observed) and 14 metres of 3.56 g/t gold from 64 metres in DH-131;
Seven metres of 3.95 g/t gold from 53 metres in DH-135;
Four metres of 3.57 g/t gold from 73 metres in DH-141.

Oromin's 2007 field program has concluded for the Christmas break with field activities scheduled to restart in early January, 2008. An additional 15 core holes and 40 reverse circulation holes were completed in 2007 for which assays are pending.

Fieldwork was carried out under the supervision of Gerald McArthur, PGeo, 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, Sask., carried out all assaying under industry-standard quality assurance/quality control procedures.

Mineralized intervals are based on one-metre composite

samples using a 0.5-gram-per-tonne gold cut-off level

with a maximum internal dilution of two metres. The

attitude of mineralized intervals varies and reported

mineralized intersections may not represent true widths.



* These holes test the north-south-trending mineralized zone,

which intersects and merges with the east-west-trending

mineralized zones of the Golouma West Deposit, as shown on the

location maps on Oromin's website.
