VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 12/15/10 -- Oromin Explorations Ltd. (TSX VENTURE: OLE)(OTCBB: OLEPF) -

New Drill Results include:

--  17.14 g/t Au over 14 metres at Golouma West
--  7.68 g/t Au over 27 metres at Golouma West
--  6.90 g/t Au over 7 metres at Kerekounda
--  4.12 g/t Au over 37 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 Senegal, West Africa. Drilling has been focused on project resource and reserve expansion with particular emphasis on Golouma Style, higher grade gold deposits and on initial definition drilling of higher grade gold potential beneath the proposed open pit at the Masato deposit.

Chet Idziszek, President and CEO of Oromin, stated, "The deepest drilling to date at Kerekounda and at Golouma West has displayed robust grades and widths. The continuity appears excellent, and remains open to further depth and lateral expansion. We have observed visible gold in numerous drill holes, all within typical veined, altered mineralized zones. Drilling is presently confirming mineralization below 550 metres in depth, whereas reserves calculated in the July 2010 Feasibility Study extended to an average depth of only 250 metres. At our Masato targets, the drill program to define underground mining potential continues to demonstrate excellent continuity of multiple zones. These zones host favourable grades, over widths amenable to cost-effective underground mining."

The new drill results, along with those previously reported in Oromin's December 1, 2010 news release, are listed below and detailed 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. Assay highlights from drilling include:

New 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)
