Oromin Announces Further Positive Drilling Results From Ongoing Resource Expansion Program

New Drill Results include:

10.05 g/t Au over 14 metres at Kerekounda
5.41g/t Au over 19 metres at Golouma West

6.94 g/t Au over 31 metres at Masato

Oromin Explorations Ltd. ("Oromin"), on behalf of Oromin Joint Venture Group Limited ("OJVG"), is pleased to provide a further update to its ongoing 2010 drilling program at the OJVG Gold Project (the "Project") in eastern Sénégal, West Africa. The current drilling is focused on project resource and reserve expansion with particular emphasis on Golouma Style, higher grade gold deposits and initial definition drilling of higher grade gold potential beneath the proposed open pit at the Masato deposit. This program is presently employing six drill rigs.

GOLOUMA STYLE DEPOSITS

As part of OJVG's intention to expand the Golouma Style deposits' higher grade resources amenable to underground mining, one objective of the current drilling campaign is to define areas of resource/reserve expansion potential at depth, below the existing Golouma West, Golouma South, Kerekounda and Kourouloulou deposits. The Golouma Deposits' indicated resources contain 1,218,000 ounces of gold. Their mineable reserves total 7,364,000 tonnes containing 960,000 ounces of gold at the diluted grade of 4.06 g/t Au. (See July 15, September 22, November 18 news releases and November 9 Short Form Prospectus for details).

The new drill results along those previously reported in Oromin's news release, dated November 18, 2010 are listed below and in Appendix A. These drill results further confirm the continuity of mineralization and increasing expansion potential for those higher grade Golouma Style deposits down-dip and below the limits of the resource/reserve block model used for the July 2010 Feasibility Study. At Golouma West for example, nine recently completed drill holes for which assays are pending, (911, 915, 917, 919, 924, 925, 927, 928, 932) have all intersected strong mineralized zones including visible gold below the Feasibility Study reserve blocks at vertical depths between 300 and 500 metres. Assay highlights from drilling include:

4.13 g/t Au over 14 at Kerekounda in DH-896		2.67 g/t Au over 7 m at Golouma West in DH-863*
10.05 g/t Au over 14 at Kerekounda in DH-900		10.14 g/t Au over 5 m at Golouma West in DH-868*
5.41 g/t Au over 19 at Golouma West in DH-901		8.12 g/t Au over 7 m at Golouma West in DH-892*

4.15 g/t Au over 12 m at Golouma South in DH-848*		*Previously reported (see news release dated November 18, 2010).

MASATO DEPOSIT - UNDERGROUND

New drill results from mineralized zones below the proposed open pit at the Masato Deposit continue to extend the zones of higher grade gold mineralization potentially amenable to underground mining. This mineralization will be remodelled for the planned resource and reserve update scheduled in Q1 and Q2 of 2011 respectively.

Key results from Masato expansion drilling include: (see Appendix B for details)

1.94 g/t Au over 16 m in DH-894		2.21 g/t Au over 4 m in DH-888*

*Previously reported (see news release dated November 18, 2010)

In the Feasibility Study completed by SRK Consulting (Canada) Inc. ("SRK") and filed in July 2010, only the near surface, open pittable portion of the indicated resources at Masato was converted to reserves that would be mined and blended with higher grade gold reserves from the Golouma Style deposits prior to CIL treatment. The Masato Deposit's measured and indicated resources contain 1,640,692 ounces of gold. The open pittable mineable reserves total 10,154,000 tonnes containing 460,000 ounces of gold at a diluted grade of 1.41 g/t Au is based on drilling to January 2010. (See September 22, 2010 news release and November 9 Short Form Prospectus for details).
