VANCOUVER, BRITISH COLUMBIA–(EMWNews – July 24, 2008) – Oromin Explorations Ltd. (TSX VENTURE:OLE)(OTCBB:OLEPF) –

– Resource shells included only to average depths of 150 to 200 metres

– Significant on-trend and to-depth potential continues to be drilled

– Subsequent drilling expands deposits and confirms new discoveries

– Pre-feasibility study to follow resource updates in Q4 2008 and early 2009

– Preliminary metallurgical tests confirm high gold recoveries

Oromin Explorations (“Oromin”) reports that it has received an initial NI 43-101 compliant resource estimate prepared by SRK Consulting (Canada) Ltd. (“SRK”) (the “SRK Report”) for the three most advanced gold deposits defined to date at the OJVG Sabodala Gold Project in eastern Senegal. Based on approximately 85,000 metres of drilling at 20 to 40-metre centres in 555 holes (to May 2008), inferred resources at the Masato, Golouma West and Golouma South Deposits total 25.2 million tonnes grading 1.73 grams per tonne gold for 1.40 million ounces of contained gold.

Oromin President, Chet Idziszek, stated, “This first resource estimate provides an initial snapshot of the ultimate potential of the Sabodala Project. We expect increases to the resource base in the fourth quarter of 2008 and early in 2009, based on our ongoing aggressive drilling programs throughout this period, estimated to total a further 100,000 metres. This drilling will focus on the on-strike and to-depth potential at the three zones reported, based on demonstrated geological evidence, and also on the 14 additional zones established to date, none of which are part of the SRK Report.”

“As evidence for this potential, note the excellent subsequent drill results at the Golouma West, Golouma South and Masato deposits, which are not included in the resources reported above, and also note the encouraging drill results at four new discoveries confirmed at Goumbati, Sabodala North, Niakafiri and Sekoto.”

All three deposits remain open to expansion both along strike and to depth. The estimated resource for the Golouma South deposit utilizes only a 400-metre strike length of the 1,065-metres drilled thus far of a 3,000-metre long gold geochemical anomaly. The Golouma West deposit has been traced over a minimum 1,500-metre length of which only a combined strike extent of 1,000 metres is incorporated into the current resource study. Similarly at Masato, the resource estimation has taken into account only a 1,700-metre strike extent whereas this deposit has now been drilled along a 2,000-metre length of this 2,600-metre long gold geochemical anomaly.

The SRK report focused only on the three most advanced deposits of seventeen known gold targets discovered to date within the 230-square-kilometre concession (please refer to the attached map). The independent report does not include subsequent drilling in approximately 130 additional drill holes that have since expanded and returned continued excellent results from the Golouma West, Golouma South and Masato deposits. Highlights from this recent drilling include:

– 11 metres of 2.82 g/t gold in DH-240 at Golouma West

– 14 metres of 2.07 g/t gold in DH-255 at Golouma West

– 9 metres of 7.77 g/t gold in DH-245 at Golouma South

– 10 metres of 5.89 g/t gold in DH-247 at Golouma South

– 22 metres of 3.81 g/t gold in DH242 at Masato

– 14 metres of 3.64 g/t gold and 28 metres of 2.56 g/t gold in DH-279 at Masato

– 14 metres of 2.73 g/t gold in RC-319 at Masato

– 7 metres of 4.60 g/t gold in RC-329 at Masato

– 27 metres of 1.93 g/t gold in RC-333 at Masato

Meanwhile, initial drilling of mineralized targets outside the scope of the SRK report has begun at Goumbati, Sabodala North, Niakafiri and Sekoto targets. Highlights from results available to-date include:

– 3 metres of 2.58 g/t gold in DH-252 at Goumbati

– 6 metres of 2.22 g/t gold in DH-260 at Sabodala North

– 6 metres of 1.65 g/t gold in RC-371 at Niakafiri

– 17 metres of 1.15 g/t gold in RC-363 at Sekoto

– 5 metres of 2.09 g/t gold in RC-364 at Sekoto

A preliminary feasibility study scheduled to follow in early 2009 will include additional metallurgical testing to confirm preliminary tests demonstrating high gold recoveries – 93% at Masato, 90% at Golouma West and 88% at Golouma South – and very low reagent consumption (0.2 to 0.4 kg/tonne for cyanide and 0.9 to 1.2 kg/tonne for lime). It is anticipated that additional testwork will optimize and increase recoveries further.

Geological modeling and gold grade estimation were carried out using Gemcom software. Capped gold assays were composited to 3.0 metre lengths and grade estimation was completed using Inverse Distance weighting to the second power (ID2). The estimate was conducted on 15x15x6-metre blocks constrained by wireframe solid models.

The initial resource estimate was conducted as a co-operative effort between Lions Gate Geological Consulting Inc. and SRK. Marek Nowak, P. Eng. of SRK, is the Qualified Person as defined under National Instrument 43-101 responsible for the resource estimates. Doug Turnbull, P. Geo., a “qualified person” for the purposes of National Instrument 43-101, has verified the non-resource information disclosed in this news release. TSL Laboratories in Saskatoon carried out all assaying under industry-standard QA/QC procedures.
