Oromin Explorations Ltd.: 2008 Drill Program Identifies Additional Gold Deposits at Sabodala-Currently Six Deposits Discovered by Oromin

2009 Prefeasibility and Advanced Exploration Drilling Program Now Underway

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 12, 2009) - Oromin Explorations Ltd. (TSX:OLE)(OTCBB:OLEPF) -

Highlights

- Three newly discovered gold deposits (Kerekounda, Niakafiri, Maki Medina) compliment three previous Oromin gold deposit discoveries (Masato, Golouma West, Golouma South)

- Resource update for all drilling to end of 2008 to be completed in January 2009, including 375 drill holes completed since initial resource calculations

- Prefeasibility study begins in January 2009

- Latest drilling results include:

-- 25 metres of 8.86 g/t gold in DH-312 at Masato

-- 14 metres of 4.53 g/t gold in RC-432 at Masato

-- 5 metres of 15.01 g/t gold and 9 metres of 5.26 g/t gold in DH-316 at Golouma South

-- 18 metres of 3.41 g/t gold in DH-371 at Golouma West

Oromin Explorations Ltd. ("Oromin"), on behalf of the Oromin Joint Venture Group ("OJVG"), is pleased to announce additional results from the ongoing step-out and in-fill drilling program at its Sabodala Exploration Concession in eastern Senegal. Oromin's 2008 drilling program has focussed on resource definition and delineation at several of its numerous gold zones and gold deposits, including the Masato, Golouma West and Golouma South gold deposits from which the Project's initial NI 43-101 resource calculation was calculated, based on drilling results from 555 drill holes completed to the end of May 2008. Subsequent to that initial calculation, 375 additional drill holes have now been completed.

Oromin is planning an update to its Sabodala Project resource to include all drilling results to the end of December 2008 which should be completed by late January 2009. In addition to further drilling at all three previously established gold deposits, (Masato, Golouma West and Golouma South), Oromin has most recently focussed on drilling programs at Maki Medina, Kerekounda and Niakafiri Southeast. Based both on prior results and on current results reported here, each of these three targets has now been upgraded to deposit status; accordingly, their initial resources will now be included in the Project's overall total. Furthermore, preliminary drilling has also been undertaken at the Sekoto, Cloverleaf and Korolo gold zones, presently the next tier of priority targets leading into 2009. Results from the property-wide exploration program continue to support Oromin's original conceptual model of multiple gold deposits within the Sabodala Exploration Concession as a key component in the rapidly developing mineral district of eastern Senegal.

MASATO DEPOSIT

The greatest distribution of drilling since Oromin's initial resource calculation has been directed at the Masato Deposit (initial inferred resource estimate of 16.6 million tonnes grading 1.25 g/t gold for 670,000 ounces of contained gold). Drilling since the resource estimate has focussed on both in-fill and extensive step-out drilling along trend as well as both up-dip and down-dip of previous drilling. The Masato Deposit; multiple, sub-parallel mineralized horizons within a broad alteration zone, has been successfully drilled for over 2.0 kilometres of strike extent and to depths exceeding 200 metres and remains open both laterally and vertically.

GOLOUMA WEST DEPOSIT

One recent hole of significance has been completed at the Golouma West Deposit (initial inferred resource estimate of 6.7 million tonnes grading 2.38 g/t gold for 520,000 contained ounces of gold), testing for the down-dip, down-plunge extension to mineralization associated with the West Limb of the Golouma West Deposit. This drill hole, DH-371, returned an 18-metre interval grading 3.41 g/t gold from a downhole depth of 369 metres. Within this wide interval, a 7-metre portion graded 5.83 g/t gold. Considerable expansion potential remains to be tested here where the potential for underground mining beneath the planned Golouma West open pit will be evaluated.

KEREKOUNDA DEPOSIT

Results received to-date at Kerekounda have delineated a continuous shear-hosted vein system over a minimum strike extent of nearly 250 metres and to a minimum down-dip extent of approximately 200 metres. Previously announced results included 52.61 g/t gold over 9 metres in DH-360, 48.68 g/t gold over 4 metres in DH-367 and 25.34 g/t gold over 7 metres in RC-463.

Oromin management is encouraged by this early-stage drilling success at Kerekounda. Based on the present geometry, continuity of the mineralized intersections and the high-grade nature of the results received to-date, Oromin considers this as an early-stage underground mining opportunity that will enhance and compliment the previously announced preliminary resources at their Masato, Golouma West and Golouma South gold deposits. The Kerekounda discovery is located 1.5 kilometres north of the Golouma South deposit.

NIAKAFIRI DEPOSIT

Oromin's Niakafiri Deposit is a direct extension of neighbouring Mineral Deposits Limited's Niakafiri Deposit which has been reported to contain approximately 540,000 ounces of gold. Oromin's portion of this gold deposit has been partially tested by grid-based drilling along a 500-metre strike extent to-date. Oromin believes that the Niakafiri Deposit lies within an approximate 8 kilometre structural trend that crosses both Oromin's and MDL's land holdings, with Oromin's Masato Deposit representing the northern portion and the Niakafiri Deposit representing the southern portion. Drilling results received to-date suggest gold mineralization at Niakafiri is very similar to that observed at the Masato Deposit: multiple, sub-parallel strike and depth, and extensive, mineralized horizons within a broad structurally controlled alteration zone.

Significant results received to-date at Niakafiri are shown in the following table:

MAKI MEDINA DEPOSIT

The Maki Medina Deposit is coincident with a gold-in-soil geochemical anomaly covering approximately 1.2 kilometres in strike extent of which the central 900 metres has been partially tested by wide spaced initial drilling. Maki Medina is located 2.0 kilometres south westerly from the Niakafiri Deposit and may represent a southward extension of the same regional structural control hosting Oromin's Masato and Niakafiri Deposits.

Significant results from recent wide-spaced drilling at Maki Medina are shown in the following table:

Oromin's geological and sub-contracted drilling crews have initiated remobilization to Sabodala to begin the 2009 advanced exploration program and Prefeasibility Study.

Doug Turnbull, P. Geo., a "qualified person" for the purposes of National Instrument 43-101, has verified the data disclosed in this news release. William Bond, P. Geo., also a "qualified person" for the purposes of National Instrument 43-101, has supervised geologic field procedures. TSL Laboratories in Saskatoon carried out all assaying under industry-standard QA/QC procedures.
