VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Dec. 21, 2006) - Oromin Explorations Ltd. (TSX VENTURE:OLE)(OTCBB:OLEPF) -

Highlights

- Step-out drilling at Golouma West returns significant gold intersections including 7.79 g/t over 9 metres, 101.7 g/t over 3 metres, 6.04 g/t over 6 metres, 9.78 g/t over 9 metres and 19.5 g/t over 5 metres

- Step-out drilling at Golouma South returns significant gold intersections including 8.55 g/t over 9 metres, 4.61 g/t over 12 metres, 9.70 g/t over 9 metres and 4.99 g/t over 16 metres

- Step-out drilling at Masato returns significant gold intersections including 2.85 g/t over 33 metres and 15.11 g/t over 12 metres

- Three new mineralized zones discovered - Maki Medina, Golouma Northwest and Golouma Northeast

Oromin Explorations Ltd. is pleased to provide results for 28 drill holes (DH-24 through DH-61) and initial results from three new gold discoveries at Golouma Northwest, Golouma Northeast and at Maki Medina.

During the 2006 exploration program, 70 core holes and 10 reverse circulation holes have been completed, primarily at the Golouma West, South, Masato and Niakafiri gold zones. 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 early 2007.

The new drill results continue to show good lateral and depth continuity of gold mineralization. The following tables outline the significant results from the Golouma West, South and Masato zones.

GOLOUMA WEST ZONE

Previous drilling has returned results that included 65 metres at 7.83 g/t gold in hole DH-17 and 20 metres @ 3.97 g/t gold in hole DH-21.

NEW DISCOVERIES

MAKI MEDINA

Of the more than thirty other new exploration discoveries identified by Oromin at Sabodala, one in particular has recently been upgraded substantially. A NE-SW trending gold-in-soil geochemical anomaly extending for approximately 1,500 metres represents this target zone, Maki Medina. Maki Medina is located approximately 3 kilometres to the southwest of MDL's Niakafiri Gold Deposit. A series of excavator trenches spaced along and across the central section of the anomalous trend has identified favourable geology, alteration and mineralization over a minimum strike length of 900 metres. Trenching results from Maki Medina include: 3.30 g/t gold over 6.0 metres (TRX-99), 2.74 g/t gold over 6.0 metres (TRX-100), 2.47 g/t over 5.0 metres (TRX-101), 1.11 g/t gold over 4.0 metres (TRX-103), 2.00 g/t gold over 23.0 metres (TRX-107), 1.56 g/t gold over 3.0 metres (TRX-109) and 1.15 g/t gold over 5.0 metres (TRX-131).

Oromin has also completed the first ever drill hole at Maki Medina (DH-69) with visually encouraging geology, alteration and mineralization in two distinct zones measuring 20 metres and 22 metres in length. Considerable exploration, including both core and RC drilling is planned for early 2007 at Maki Medina.

GOLOUMA NORTHWEST

Another of Oromin's exploration discoveries, located approximately 350 metres to the north of Golouma West, Golouma Northwest, was recently trenched with favourable results of: 5.08 g/t gold over 9 metres (TRX-111), 2.22 g/t gold over 16 metres and 5.72 g/t gold over 12 metres (TRX-112), 3.50 g/t gold over 4 metres (TRX-113) and 2.25 g/t gold over 4 metres (TRX-125). Additional trenching and 3 core holes (DH-62, 65 and 66) have been completed at Golouma Northwest with further exploration activity planned in 2007.

GOLOUMA NORTHEAST

Oromin has completed 2 core holes (DH-67, 68) and started a third (DH-70) at Golouma Northeast which is located approximately 500 metres to the Northeast of the Golouma South Zone. Golouma Northeast is an area of extensive and deep artisanal pits and excavations from which Oromin has previously reported rock sample results of up to 27.54 g/t gold. Both of Oromin's completed holes have intersected favourable alteration and veining including the presence of visible gold. The third hole will be completed following the current Christmas break.

OTHER RECENT EXPLORATION

Oromin has initiated considerable infill soil geochemical sampling at various target zones throughout the Sabodala Property, initiated trenching at Sabodala North and the north extent of Masato and undertaken detailed induced polarisation geophysical surveying at Sekoto, Maki Medina, Golouma West and Niakafiri.

Oromin will continue with and expand on their aggressive multi-faceted exploration program in 2007.

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.

A complete listing of all available 2006 drill and trench results, along with a location map, will be posted on the Oromin website.
