CORE AND REVERSE CIRCULATION DRILLING

CONTINUES TO IDENTIFY AND EXPAND

HIGH GRADE MINERALIZATION AT SABODALA

HIGHLIGHTS

DRILLING AND TRENCHING TO DATE AT GOLOUMA WEST AND GOLOUMA SOUTH RETURNED A WEIGHTED AVERAGE OF 6.0 G/T GOLD AND 6.3 G/T GOLD OVER AVERAGE LENGTHS OF 8.1 METRES AND 8.8 METRES, RESPECTIVELY; SIGNIFICANT NEW INTERSECTIONS INCLUDE:

14 METRES OF 7.36 G/T GOLD IN RC-49

11 METRES OF 14.35 G/T GOLD IN RC-60

4 METRES OF 33.58 G/T GOLD IN RC-66

8 METRES OF 9.47 G/T GOLD IN DH-84

16 METRES OF 6.60 G/T GOLD IN RC-26

DRILLING TO DATE AT MASATO RETURNED A WEIGHTED AVERAGE OF 2.9 G/T GOLD OVER AN AVERAGE LENGTH OF 14.6 METRES.

INITIAL DRILLING AT MASATO NORTH AND MAKI MEDINA INTERSECTED ENCOURAGING RESULTS INCLUDING 22 METRES OF 1.8 G/T GOLD AND 12 METRES OF 2.69 G/T GOLD, RESPECTIVELY.

Oromin Explorations Ltd. (TSX-V:OLE; OTC/BB-OLEPF) is pleased to provide additional stepout and infill results from drilling at the Golouma West and Golouma South deposit areas and initial results from core drilling at the Masato North and Maki Medina gold zones. Reverse circulation drilling is continuing at Golouma West. Core drilling continues at both Golouma Northeast and Masato while initial drilling is now underway at the Kobokoto target.

Oromin is pleased with the continuity and grades observed in drilling completed to date at the Golouma South, Golouma West and Masato deposits. As a result of this drilling and regional exploration program results, the Sabodala Property has been shown to host multiple deposits. Oromin’s 2007 exploration program is focussed on resource delineation of Sabodala’s numerous gold zones and deposits, with more than 75,000 metres in 450 holes planned.

GOLOUMA WEST GOLD DEPOSIT

The deposit has been traced over 850 metres on surface and to 300 metres at depth and remains open in all directions. Oromin is currently drilling the deposit at 40 metre centres using an RC drill rig to a 200 to 250 metre depth which will be followed by deeper drilling with diamond core rigs. Newly drilled mineralized sections are listed in the attached schedule; the more significant of which are:

14 metres of 7.36 g/t gold in RC-49

11 metres of 14.35 g/t gold in RC-60

4 metres of 33.58 g/t gold in RC-66

Based on drilling and trenching to date (52 drill holes and 17 trenches), a weighted average of 6.0 g/t gold has been calculated by management over an average mineralized intersection length of 8.1 metres* for the deposit. (The minimum mineralized interval used in the calculations is 2 metres and grades were not cut). The intersection grade varies to 60.70 g/t gold over 7 metres in DH-17 and lengths to 29 metres grading 2.08 g/t gold in DH-24. Additionally, 20 of the 52 drill holes completed to-date (38%), display two or more zones of mineralization.

*There is insufficient information at this time to determine if this represents a true width of the mineralized zone.

GOLOUMA SOUTH GOLD DEPOSIT & GOLOUMA NORTHEAST TARGET

The Golouma South gold deposit has been traced over 400 metres on surface and to 200 metres at depth and remains open to the north, south and west. Furthermore, Oromin believes that this deposit is related to the Golouma Northeast target located approximately 500 metres to the northeast. (To date, drilling at Golouma Northeast has returned gold intersections including 98.37 g/t gold over 3 metres in DH-72 and 17.61 g/t gold over 8 metres in DH-73). Oromin is drilling the Golouma South deposit at 40 metre centres using an RC drill rig to a 200 to 250 metre depth to be followed by deeper drilling using diamond core rigs. Newly drilled mineralized sections are listed in the attached schedule; the more significant of which are:

8 metres of 9.47 g/t gold in DH-84

16 metres of 6.60 g/t gold in RC-26

Based on drilling and trenching to date (37 drill holes and 8 trenches) a weighted average of 6.3 g/t gold has been calculated by management over an average mineralized intersection length of 8.8 metres* for the deposit. (The minimum mineralized interval used in the calculations is 2 metres and grades were not cut). The intersection grades vary to 24.58 g/t gold over 9 metres in RC-10 and lengths to 20 metres at 3.65 g/t gold in DH-89. Additionally, 20 of the 52 drill holes completed to-date (32%), display two or more zones of mineralization.

*There is insufficient information at this time to determine if this represents a true width of the mineralized zone.

MASATO NORTH TARGET

Initial drilling results from the recently discovered Masato North target returned up to 1.8 g/t gold over 22 metres in DH-91. Masato North is presently defined by a strong gold-in-soil geochemical anomaly measuring 800 metres in length connected disjointedly with the Masato deposit.

Trenching at Masato North returned 1.04 g/t gold over 13 metres, 1.07 g/t gold over 21 metres and 2.03 g/t gold over 9 metres. The attached schedule lists the results from the initial four holes completed here.

MASATO GOLD DEPOSIT

The Masato deposit is coincident with a large and strong gold-in-soil geochemical anomaly 1.8 kilometres in length by up to 1.2 kilometres in width. It is connected disjointedly with the Masato North target and is located 1.2 kilometres due east of the 1.9 million ounce Sabodala Gold deposit owned by Mineral Deposits Limited (“MDL”) that is being readied for production (see MDL May 4, 2007 news release). This large geochemical anomaly is also coincident with 3 parallel I.P. chargeability anomalies of which only the westernmost has been drilled to date.

Based on 8 core holes completed by Oromin, and 7 historic holes completed by BRGM, a weighted average of 2.9 g/t gold has been calculated by management over an average mineralized intersection length of 14.6 metres* for the deposit. (The minimum mineralized interval used in the calculations is 2 metres and grades were not cut). The grades vary to 12 metres at 15.11 g/t gold in Oromin hole DH-39 and lengths vary to 39 metres at 1.83 g/t gold in Oromin hole DH-09.

Diamond core drilling has re-started at the Masato deposit, to be followed by RC drilling at 40 metre centres over its entire length, including Masato North. In addition, the other two coincident IP chargeability anomalies will be trenched and drill tested.

*There is insufficient information at this time to determine if this represents a true width of the mineralized zone.

MAKI MEDINA TARGET

The Maki Medina target is a geochemically anomalous gold-in-soil trend extending for approximately 1,500 metres. Prior to Oromin’s initial drilling at Maki Medina, a series of excavator trenches identified favourable geology, alteration and mineralization from which trenching results included: 3.30 g/t gold over 6 metres, 2.74 g/t gold over 6 metres, 2.47 g/t gold over 5 metres, 2.00 g/t gold over 23 metres, 1.56 g/t gold over 3 metres and 1.15 g/t gold over 5 metres. Initial drilling results returned up to 2.69 g/t gold over 12 metres in DH-75. The attached schedule outlines the results from the initial seven holes completed here.

REGIONAL EXPLORATION

In addition to the extensive reverse circulation and core drilling programs, regional exploration including soil sampling, prospecting, ground geophysics and trenching is also underway at a variety of favourable target areas throughout the Sabodala Property. Priority exploration areas within this target group, where drilling is planned, include: Niakafiri, Sekoto, Kinemba, Korolo, Goumbati, Sabodala North, Dendifa, Maleko and Bransan.

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.

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