Oromin Explorations Ltd.: Sabodala Sampling, Trenching and Geophysics Expanded

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Oct. 21, 2005) - Oromin Explorations Ltd. (TSX VENTURE:OLE) -

HIGHLIGHTS

- TRENCHING, SAMPLING AND PROSPECTING EXPANDED AS A RESULT OF CONTINUED EXPLORATION SUCCESS

- MECHANICAL TRENCHING AT GOLOUMA GENERATES ADDITIONAL DRILL TARGETS

Oromin Explorations Ltd. is pleased to provide an update for its Sabodala Property in eastern Senegal. Oromin's exploration program of trenching, infill and step-out soil sampling, prospecting and mapping is continuing throughout the Golouma area and, as a result of favourable structure, alteration and veining encountered in both the current and the initial trenching programs, has now been expanded to include 500 to 1,000 metre spaced reconnaissance lines across the entirety of the exploration concession. Manual trenching is also underway along the extensive soil geochemical anomaly that trends southward from the adjacent Sabodala South deposit of Minerals Deposits Limited.

Oromin's mechanical trenching program is progressing rapidly with a total of 20 new long trenches distributed across four areas of the 1.5 by 2.0 kilometre Golouma gold-in-soil geochemical anomaly. The expanded trenching within these four areas has uncovered similar intensity of shearing, alteration and veining as that previously observed within Oromin's three initial manual trenches at Golouma and all of these areas contain one or more drill targets. The results from the three initial trenches, an old trench sampled in 2004 by Oromin's consulting geologist and a series of shallow hand trenches within the same area sampled in 1987 by BRGM (Geologic Branch of the French Government) are as follows:



Trench # Sampled By Width (metres) Gold (g/t)
OLE-01 Oromin 18.5 + 2.96
including 9.5 4.50
OLE-02 Oromin 2.0 + 0.30
OLE-03 Oromin 5.5 30.22
including 2.0 68.59
Pit B Consultant 3.1 + 11.79
GOL T32 BRGM 4.0 + 3.39
GOL T33 BRGM 6.5 + 11.40
GOL T35 BRGM 5.5 + 5.40
GOL T36 BRGM 5.8 + 7.00


As the number and size of the favourable exploration targets expand, Oromin will continue to evaluate and priority-rate each area. More than 2,500 soil, rock and trench samples have been collected during the current phase of exploration, which began in late August, and results for these samples will be reported as Oromin receives grouped results for each sample area. Oromin expects to collect at least another 2,500 soil and trench samples in advance of drilling.

In addition to this ongoing fieldwork, Sigma Geophysics has returned to the Sabodala Property to continue to expand Oromin's induced polarisation (IP) geophysical survey. Based on the favourable results observed during the initial IP survey, Sigma will utilise a refined set-up array to enable greater depth penetration for the chargeability and resistivity signals.

Although Oromin had expected drill rigs to be on site by mid October, as a result of shipping and clearance delays beyond Oromin's control, the drill rigs are now expected to be on site at Sabodala by mid to late November. While these shipping delays will also delay the completion plan of Oromin's exploration camp and field office infrastructure, they afford Oromin an opportunity to carry out additional geological, geochemical and geophysical work on the continually expanding target areas at Sabodala prior to the commencement of drilling.
