Oromin Explorations Ltd.: Initial 2011 Drilling Results Continue Providing Positive Grade and Thickness Intervals at the OJVG Gold Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 3, 2011) - Oromin Explorations Ltd. (TSX:OLE)(OTCBB:OLEPF) -

HIGHLIGHTS

New Drill Results include:

  • 15.66 g/t Gold over 7 metres at Masato
  • 5.15 g/t Gold over 10 metres Masato
  • 46.75 g/t Gold over 2 metres at Golouma West
  • 9.25 g/t Gold over 4 metres at Golouma West

Oromin Explorations Ltd. ("Oromin"), on behalf of Oromin Joint Venture Group Limited ("OJVG"), is pleased to provide the initial results from its 2011 exploration drilling program at the OJVG Gold Project in eastern Senegal, West Africa. Current drilling commenced in mid-January 2011 and plans for 2011 include: broader-spaced lateral and depth extension drilling to the five primary gold deposits at Golouma West, Golouma South, Kerekounda, Kourouloulou and Masato; follow-up drilling at recent discoveries such as Kinemba and Koutouniokolla; and initial drilling evaluation at many of Oromin's new prospects including Saboraya, Kourouloulou South and Mankana.

Chet Idziszek, Oromin's President and CEO, stated, "We continue to expand the known limits of our deposits at an aggressive pace. Our increasing knowledge of the geology and the continuity of mineralization observed in our step out drilling to date is giving us even greater confidence to step out much more widely on a number of zones, particularly at depth, than we would for resource delineation. Our main focus for 2011 will be to demonstrate how deep and far out along strike these mineralized systems at the Golouma and Masato deposits extend beyond the limits of the current resource models. Also included in our plans for 2011 will be the evaluation of a number of new targets. We are eager to receive our first drill results from these areas and are very encouraged by what we are seeing from initial drilling at Saboraya, Kourouloulou South and the 950 zone at Golouma West."

The new drill results, along with those previously reported in Oromin's February 3rd, 2011 news release are listed below and detailed with included intervals in Appendix A and B. These drill results further confirm the continuity of and increasing potential to expand mineralization 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.

    10.26 g/t Au over 3 m in DH-947
    6.00 g/t Au over 28 m in DH-948

At the Masato Deposit, new results from mineralized zones below the proposed open pit continue to confirm and extend the zones of higher grade gold mineralization potentially amenable to underground bulk mining. The Masato Deposit mineralization will be modelled as a combined Open Pit and Underground operation for the planned resource update scheduled in Q1 of 2011.
