Include Deepest Intersections To Date
VANCOUVER, BRITISH COLUMBIA, Jan. 12, 2011 (Marketwire) --
HIGHLIGHTS
-- 46.04 g/t Gold over 11 metres (396 to 407 metres) in DH-927 at Golouma
West represents one of the highest "grade x thickness" intervals drilled
thus far
-- Two mineralized zones of 5.54 g/t Gold over 8 metres (558 to 566 metres)
and 12.2 g/t Gold over 8 metres (590 to 598 metres) in DH-928 at Golouma
West represent the deepest drill intersections thus far
-- Additional New Drill Results include:
-- 8.79 g/t Gold over 13 metres at Golouma West
-- 8.90 g/t Gold over 7 metres at Golouma South
-- 9.52 g/t Gold over 6 metres at Masato
-- 3.95 g/t Gold over 15 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 drilling program at the OJVG Gold Project (the "Project") in eastern Senegal, West Africa. Drilling in the latter part of 2010 focused on resource and reserve expansion with particular emphasis (1) on Golouma Style higher grade gold deposits, and (2) 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, "Results from our deepest drilling to date at Golouma West have confirmed excellent continuity of robust grades and favourable widths. Drilling has confirmed mineralization in multiple zones to at least 600 metres in depth, which is more than twice the average depth of 250 metres to which the reserves were calculated in the July 2010 Feasibility Study. Based on our drilling to date, all of the mineralized zones at the Golouma Style deposits remain open to depth and along strike."
The new drill results, along with those previously reported in Oromin's December 1 and December 15,2010 news releases are listed below and detailed with included intervals 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. The reserves from the Golouma Style Deposits in the July 2010 Feasibility totalled 960,000 ounces (7.4 million tonnes at 4.06 g/t Au) while indicated resources totalled 1.2 million ounces (10.5 million tonnes at 3.59 g/t Au) and an additional 149,000 inferred ounces (1.1 million tonnes at 4.15 g/t Au) - See our July 15, September 22 and November 18, 2010 News Releases and our November 9, 2010 Short Form Prospectus for details.
Of particular note are drill holes DH-925, DH-927, DH-928, DH-932 and DH-935 which represent some of the deepest intersections to date at the Golouma West deposit. DH-927 intersected 46.04 g/t gold over 11 metres at 396 metres representing one of the highest "grade x thickness" intervals from drilling thus far. Hole DH-928 intersected two gold zones at depth, 5.54 g/t gold over 8 metres at 558 metres and the deepest drill intersection to date, 12.2 g/t gold over 8 metres at 590 metres. Assay highlights from drilling include:

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 mining. The Masato Deposit mineralization will be modelled as a combined Open Pit and Underground operation for the planned resource and reserve updates scheduled in Q1 and Q2 of 2011 respectively.
Key results from Masato expansion drilling include: (see Appendix B for included intervals)
