Oromin Explorations Ltd.: New Gold Discoveries at Golouma Northeast and Northwest Confirmed by Drilling

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 5, 2007) - Oromin Explorations Ltd. (TSX VENTURE:OLE)(OTCBB:OLEPF) -

HIGHLIGHTS

- INITIAL DRILLING AT GOLOUMA NORTHEAST DISCOVERY RETURNS HIGH-GRADE GOLD INTERSECTIONS INCLUDING 98.37 G/T GOLD OVER 3 METRES AND 17.61 G/T GOLD OVER 8 METRES.

- STEP-OUT DRILLING AT GOLOUMA WEST RETURNS ANOTHER HIGH GRADE GOLD INTERSECTION OF 74.71 G/T GOLD OVER 3 METRES.

- REVERSE CIRCULATION DRILLING AT GOLOUMA SOUTH IDENTIFIES A NEW PARALLEL ZONE AND CONTINUES TO CONFIRM AND EXPAND MINERALIZATION INCLUDING 8.84 G/T GOLD OVER 7 METRES AND 3.58 G/T GOLD OVER 12 METRES.

- DRILLING INITIATED TO TEST A NEW ZONE, MASATO NORTH, WHERE STRONG GOLD-IN-SOIL GEOCHEMISTRY HAS BEEN CONFIRMED BY TRENCHING.

Oromin Explorations Ltd. is pleased to provide results from the initial core drilling at the Golouma Northeast and Golouma Northwest gold discovery areas. In addition, results from core drilling at the Golouma West gold zone and reverse circulation drilling at the Golouma South gold zone are also presented. Also, a core drill has moved to initiate drilling evaluation at the Masato North discovery and drilling is continuing at the Maki Medina gold discovery with results pending.

For location of all mineralized zones please refer to the Oromin website.

GOLOUMA NORTHEAST DISCOVERY

The Golouma Northeast discovery 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. No previous drilling has ever been undertaken at the Golouma Northeast discovery.

As previously reported, visible gold was intersected in two of the holes completed. The zone has been intersected over a 100 metre extent and to a depth of 150 metres. The mineralization remains open in all directions and will be the focus of follow-up drilling.

The following table outlines the significant results from Oromin's initial six of seven holes completed for which assay results are available:

GOLOUMA WEST ZONE - TWO ADDITIONAL CORE HOLES COMPLETED

At the Golouma West Zone two drill holes were completed during this period. Previous drilling has returned results that included 65 metres at 7.83 g/t gold in hole DH-17, 20 metres at 3.97 g/t gold in hole DH-21, 9 metres at 7.79 g/t gold in hole DH-50, 9 metres at 9.78 g/t gold in hole DH-55 and 3 metres at 101.7 g/t gold in hole DH-51.

In addition, Oromin has initiated an extensive reverse circulation drilling program based on a 40 metre drill hole spacing on 40 metre drill sections across the entirety of the known area of mineralization over a minimum strike extent of 750 metres. The current sectional drilling evaluation is a precursor to a resource evaluation.

GOLOUMA SOUTH ZONE - PARALLEL ZONE IDENTIFIED

At the Golouma South Zone, previous 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 and 9 metres at 24.58 g/t gold in RC-10.

Sectional drilling at 40 metre intervals continues to the south and northerly directions along the northeast trend of the mineralized zone. The mineralized zone has been intersected on all sections and it remains open in all directions. To the south, the sections include:

Incl.122-125 3 3.87


In addition, a second parallel zone has been interpreted on sections 040S and 060S to the north. The main zone intersected in hole RC-8 returned 11.9 g/t gold over 8 metres followed by a parallel zone which returned 3.13 g/t gold over 16 metres. These two zones were also intersected in hole RC-5 which returned 9.8 g/t gold over 4 metres followed by a parallel zone that returned 3.73 g/t gold over 15 metres. Current, follow-up RC drilling has intersected similar altered sections in holes RC-26 to 30 for which assays are pending.

GOLOUMA NORTHWEST DISCOVERY - INITIAL THREE CORE HOLES COMPLETED

The Golouma Northwest discovery is located approximately 350 metres to the north of Golouma West. Previous trench results extending along a minimum strike extent of 250 metres includes: 5.08 g/t gold over 9 metres, 5.72 g/t gold over 12 metres, 3.50 g/t gold over 4 metres and 2.25 g/t gold over 4 metres. To-date, Oromin has drilled only three core holes over a limited extent of the Golouma Northwest mineralized zone. Follow-up drilling is planned. The following table outlines the significant results from these drill holes at Golouma Northwest:

All drill hole assay intervals within this release are based on one metre sample composites and a 0.5 g/t gold lower cut-off. The attitude of mineralized intervals varies and may not represent true widths.

MASATO NORTH DISCOVERY - CORE DRILLING STARTED

Masato North, is represented by a strong gold-in-soil geochemical anomaly extending for approximately 1,000 metres immediately on trend and beyond previous drilling at the Masato gold zone. Results from a series of widely spaced trenches have confirmed strong gold mineralization, including: 1.04 g/t gold over a minimum of 13 metres in TRX-133, 1.07 g/t gold over 21.0 metres including 2.13 g/t gold over 6 metres and an additional 2.34 g/t gold over 6 metres in TRX-134 and 2.03 g/t gold over 9 metres in TRX-143. Additional trenching is planned beyond the areas tested thus far. A core drill has been moved to Masato North and drilling has begun.

Verification of data disclosed in this news release was carried out by Douglas Turnbull, P.Geol., and fieldwork was carried out under the supervision of Gerald McArthur, P.Geol., both are "qualified persons" for the purposes of National Instrument 43-101. TSL Laboratories in Saskatoon, Saskatchewan carried out all assaying.
