Oromin Explorations Ltd. ("Oromin") (TSX:OLE - News)(OTC.BB:OLEPF - News), on behalf of the Oromin Joint Venture Group ("OJVG"), is pleased to provide an exploration update for the ongoing exploration program at its Sabodala Gold Project in eastern Senegal, West Africa.
Oromin is also pleased to report that Ken Kuchling, P.Eng., has been appointed as Oromin's Vice-President of Engineering. Mr. Kuchling is a Professional Mining Engineer with 28 years experience in the operations and consulting industries with numerous commodities including gold, diamonds, potash, copper and molybdenum. Mr. Kuchling has a well-rounded engineering background, consisting of direct involvement in pre-feasibility and feasibility studies, international due diligence reviews, project permitting, mine geology, geotechnical engineering, tailings engineering, mine design and equipment selection. He holds a Bachelor's degree in mining engineering from McGill University, a Master's degree in mining engineering from the University of British Columbia and is a Registered Professional Engineer in Canada. Mr. Kuchling will oversee the optimization work currently underway as Oromin continues its development of Sabodala.
Recent exploration activities include in-fill and step-out resource drilling at the Epsilon deposit, step-out resource drilling towards delineating underground potential at both Golouma West and Golouma South deposits, trenching at Kobokoto, soil geochemical sampling at various target areas and prospecting at Maki Medina, and the newest discovery at Kotouniokolla.
EPSILON DEPOSIT
Drilling is continuing at the Epsilon deposit where multiple NE and NW trending quartz vein systems have been intersected in trenching and drilling within a surface area of approximately 400 metres by 400 metres. Drilling to date has intersected the main Epsilon vein systems over a minimum strike extent of 180 metres and consistently to depths of 150-200 metres below surface in multiple zones. The Epsilon vein systems remain open along strike and to depth.
Significant results from recent drilling at Epsilon are summarized in the following table:

GOLOUMA WEST AND GOLOUMA SOUTH DEPOSITS
Oromin has recently completed a series of deep drill holes at both the Golouma West and Golouma South deposits targeting higher grade mineralization down-dip from previously defined resources. These drill holes expand the mineralization beyond the current resource outlines and enhance the underground mining potential at both of these gold deposits. Significant results available from this recent deep drilling program are summarized in the following table:

mineralized intervals varies and reported mineralized intersections may not

Additional deep drilling is scheduled towards better defining the underground mining potential at both Golouma West and Golouma South.
MASATO DEPOSIT
A number of drill holes completed along the strike length of the near surface Masato oxide deposit were drilled to provide detailed Specific Gravity Determination values and assist with geological interpretation of the oxide zones previously identified. This set of in-fill core holes provided some very encouraging interval widths and grades. Material from these drill holes has been collected under the supervision of Ausenco Minerals Canada Ltd. and submitted for detailed metallurgical test work focusing on the heap leach amenability for the Masato oxide resource. Significant results from these drill holes are summarized in the following table:

REGIONAL EXPLORATION
KOBOKOTO ALPHA PROSPECT
The Kobokoto Alpha prospect is presently defined by a greater than 100 ppb gold-in-soil geochemical anomaly, displaying both NW and NE trending structures, over a 150-metre by 600-metre area. This target demonstrates one of the highest grade gold-in-soil anomalies anywhere on the OJVG Sabodala Property, with 15 soil samples in excess of 1.0 g/t gold including high values 10.8 g/t, 12.1 g/t and 29.3 g/t gold.
A series of excavator trenches completed over the Kobokoto Alpha anomaly has verified the two structural orientations. Two trenches in particular, TRX-316 and TRX-317, have both successfully intersected an undrilled NW-trending mineralized zone as follows:
�
- TRX-316 2.91 g/t gold over 9 metres (including 6.66 g/t gold
over 3 metres)
- TRX-317 483.7 g/t gold over 6 metres (including 1,419 g/t gold
over 2 metres)
Drilling is now under way at the Kobokoto Alpha Prospect.
NEW DISCOVERY - KOTOUNIOKOLLA
Recent prospecting has identified a new gold discovery, Kotouniokolla, located approximately 3.5 kilometres southwest of the Golouma South deposit. A detailed soil sampling grid over this area has outlined a greater than 100 ppb gold-in-soil anomaly measuring 250 metres in a NW-SE orientation and 450 metres in a NE-SW orientation. A total of ten rock samples, collected along an approximate 150-metre extent at Kotouniokolla, have returned favourable results including high values of up to 4.05 g/t gold, 5.42 g/t gold, 29.51 g/t gold and 269.4 g/t gold. The range of the results from these ten samples was 0.16 g/t gold to 269.4 g/t gold.
Additional prospecting, trenching and drilling are planned for the next phase of evaluation at Kotouniokolla.
