Oromin Explorations Ltd.: OJVG Gold Project-Status of Feasibility Study

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 12/12/12 -- Oromin Explorations Ltd. (TSX: OLE) (OTCBB: OLEPF), on behalf of Oromin Joint Venture Group Ltd. ("OJVG"), provides this update on the status and expected timing of a complete Carbon-in-Leach ("CIL") Feasibility Study on the OJVG Gold Project in the Republic of Senegal, and of an updated Preliminary Economic Assessment ("PEA") of certain heap leach potential at this project.

Our engineering consultants, SRK Consulting (Canada) Inc. and Ausenco Solutions Canada Inc., advise that results of the CIL Feasibility Study and PEA update are progressing well towards being available in the second half of January 2013. The deferral of this target date, previously expected by the end of Q4 2012, is in part due to the new resource model driving more significant physical and economic updates than were anticipated, and in part due to the Christmas Holiday period affecting various work and delivery schedules. This brief delay will allow the consultants to incorporate the most current estimates of capital and operating costs into the related financial analysis for the project's revised production schedule.

Our consultants have advised us that the process of establishing mining schedules and reserve estimates which will be evaluated in the Feasibility Study technical and economic model is very well advanced. As could be inferred from our announcement of an expanded resource base in the resource update made in our news release of October 1, 2012, we expect the capital and operating parameters of the updated studies will embrace significantly increased mineral processing quantities and mine lives from those set out in our 2010 CIL Feasibility Study and 2011 heap leach PEA.
