Oromin provides Exploration and Development Highlights and 2010
Objectives for OJVG Sabodala Gold Project

Oromin Explorations Ltd. (“Oromin”), on behalf of the Oromin Joint Venture Group (OJVG), is
pleased to review exploration and development highlights and 2010 objectives for the OJVG
Sabodala Gold Project in eastern Senegal, West Africa.
Continuing Successful Exploration Results and Development Progress in 2009:
• 212 sq km property position in West Africa’s fastest growing gold camp, with one
operating mine and more than 10 million ounces of gold resources reported to date by
the various Companies with holdings in this camp.
• Oromin has defined 7 gold deposits, 4 new discoveries and 18 gold targets within a 22-
km-long, 5-to-8-km wide, northeast-trending structural corridor within the OJVG
Concession.
• Eastern Side of the Corridor hosts four Golouma Style Higher Grade deposits with
combined open-pit and underground potential, similar to shear-hosted vein-type deposits
hosted in greenstone belts, as occur in Canada’s Kirkland Lake and Red Lake gold
camps and Ghana’s producing gold camps in West Africa. These gold camps are known
for deposits with high gold grades, considerable lateral and vertical extensions and very
long mine lives.
• Western Side of the Corridor hosts three Masato Style Bulk Tonnage open-pit deposits,
numerous similar targets and prospects, as well as the adjacent Sabodala open-pit gold
deposit being mined by Mineral Deposits Limited (MDL) of Australia at its 20-sq-km
concession.
• Existing resource of 2.19 M oz. Indicated and 0.35 M oz. Inferred is based on drilling
only to May 2009 and does not include mineralization drilled below conceptual open
pits used to constrain this resource calculation or drilling of five new discoveries, one of
which, Kourouloulou, has been upgraded to deposit status. For resource details please
refer to Oromin’s News Release dated November 20, 2009.
• Preliminary CIL metallurgical results are excellent, yielding recoveries of 90% at
Golouma West and Golouma South, 95% at Masato and 96% at Kerekounda.
• 184 holes (130 core, 39 RC and 15 exploration holes) drilled since the May 2009
resource calculation to year-end 2009, successfully focused on adding deep higher-grade
underground resources at Kerekounda and other advanced deposits and developing new
higher grade open-pit resources at Kourouloulou and several other recent discoveries.
• Financings totalling $26.9 Million completed in 2009, primarily to advance Sabodala,
resulting in IAMGOLD acquiring a 16% equity stake in Oromin.

2010 Objectives
• Government Mining Permit expected shortly, following recent approval of the
Company’s Strategic Environmental Evaluation (SEE) Report.
• Upgraded feasibility study in progress and scheduled for completion at the end of Q2
2010, to allow OJVG to fast-track development of the project.
• Decision to advance to feasibility rather than optimize the August, 2009 engineering
study based on rapidly expanding potential of the project.
• Q2 2010 Feasibility Study will be based on an updated resource estimate for five
advanced deposits (Golouma West, Golouma South, Masato, Kerekounda,
Kourouloulou) and two other deposits (Niakafiri SE and Maki Medina).
• Feasibility Study to focus on a proposed open-pit/underground mine complex, with
initial production from five deposits feeding a central carbon-in-leach (CIL) mill with a
capacity of 4,400 tonnes per day (TPD). Mill capacity can be increased to about 7,000
TPD when processing soft oxide and saprolite ores.
• Preliminary gold recoveries of 80% for Masato’s oxide mineralization suggest potential
for future heap leach mining. This opportunity will continue to be evaluated, however
the higher daily throughput option (CIL) currently appears more favourable.
• Four drills presently assigned to feasibility engineering and geotechnical drill program.
• Three additional drills being mobilized to continue advanced exploration and resource
drilling including deeper evaluation targeting higher-grade underground resource
expansion at all of the known deposits.
• OJVG working towards reporting resources at four new discoveries – Golouma
Northwest, Kobokoto, Koulouqwinde and Koutouniokollo – after completion of the
Feasibility Study.
• Regional exploration will aggressively continue to evaluate 18 high-potential gold
targets.
• Environmental and Social Impact Assessment to be completed in 2010.
• Social programs and community consultation have resulted in strong government and
local support for the project and will continue in the years ahead.
Drilling Extends Mineralization at Deposits and Expands Resource Potential
Previous resource drilling (to May 2009) has focused on the Golouma Style Higher Grade
deposits (Golouma West, Golouma South, Kerekounda and Kourouloulou) on the Eastern Side
of the Corridor and the Masato Style Bulk Tonnage open pit deposits (Masato, Niakafiri SE and
Maki Medina) on the Western Side of the Corridor. (See attached map and resource table).
More recent drilling is primarily focused on outlining additional resources at the Golouma area
deposits within the Golouma Style Higher Grade Gold Trend, including drilling the high-grade,
down-dip extensions of current indicated resources at the Kerekounda, Golouma West and
Golouma South Deposits and defining two recent high-grade discoveries, Kourouloulou
(formerly Epsilon) and Koulouqwinde (formerly Cloverleaf).
These deposits are all situated within easy trucking distance of each other. Potential exists for
some of the higher grade deposits to coalesce at depth.
Underground drill testing is generally on 20-metre spacings; initial open-pit testing is on 40-
metre spacings and is reduced to 20-metre spacings where deemed necessary.
The attached tables set out selected historic and recent drilling results at each of the advanced
deposits with existing resources, or which have been or are poised to be upgraded to deposit
status.
Golouma Style Higher Grade Gold Trend
Golouma West Deposit:
• 24 new core holes have been drilled at Golouma West beyond the drill-holes used in last
year’s resource estimate. This drilling has targeted higher grade mineralization as deep
step-out holes, both down-dip and laterally from previously defined Indicated
Resources. Drilling thus far has tested the Golouma West deposit over a strike extent of
1,100 metres and to average down-dip depths of 420 metres. Favourable results have
confirmed expansion opportunities both laterally and to depth at this advanced open-
pit/underground deposit.
• Recent highlights include hole DH-539, which returned 17.54 g/t gold over 10 metres,
and hole DH-617, which returned 10.04 g/t gold over 8 metres. Hole DH-617 is the
deepest down-dip intersection within one of the high-grade shoots comprising the
underground mining opportunity at the Golouma West deposit. The 10.04 g/t gold over
8 metre intersection in hole DH-617 is located at a down-dip depth of 350 metres, 30
metres further down-dip below DH-539, and is an excellent example of resource-
additive higher grade targeting of the underground deep-drilling resource program.
• The Golouma West Deposit remains open for expansion both to depth and to the North
and South on the Western limb.
Golouma South Deposit:
• Nine new core holes have been drilled at Golouma South beyond the drill-holes used in
last year’s resource estimate. This drilling has also targeted higher grade mineralization
as deep step-out holes, both down-dip and laterally from previously defined indicated
resources. Drilling thus far has tested the Golouma South deposit over a strike extent of
650 metres and to average down-dip depths of 250 metres.
• Favourable results to date have confirmed expansion opportunities laterally and at depth
at this advanced open-pit/underground deposit.
• Recent deep drilling results continue to intersect strong mineralization beyond previous
resource outlines including 8.01 g/t gold over 6 metres and 12.24 g/t gold over 7 metres
both of which are in excess of 250 metres depth. The deposit remains open for
expansion both to depth and laterally along trend.
Kerekounda Deposit:
• 24 new core holes and 13 RC holes have been completed to year-end 2009 since the
previous resource estimate, primarily as deep step-outs targeting higher grade
mineralization both down-dip and laterally from previously defined Indicated Resources.
These successful holes have confirmed that the higher grade zones comprising the
combined open-pit/underground deposit remain open to expansion, both laterally and to
depth, providing a future resource expansion opportunity. Drilling thus far has tested the
Kerekounda deposit over a strike length of 390 metres and to average down-dip depths
of 450 metres. Results from these holes will be included in the Q2 2010 resource
update.
• Drilling highlights include 15.33 g/t gold over 12 metres and 10.12 g/t gold over 13
metres and 25.34 g/t gold over 7 metres. Recent deep drilling continues to return
positive results, notably 7.17 g/t gold over 9 metres and 7.89 g/t gold over 4 metres both
of which are below 350 metres in depth.
• The deposit remains open for expansion both to the south and to depth.
Kourouloulou Deposit (formerly Epsilon):
• 66 new core holes and 3 new RC holes were drilled at this newly discovered open-
pit/underground deposit. This drilling outlined a multiple quartz vein system over a
strike length of 220 metres and to depths of 200-225 metres. Results from these 69
holes (plus subsequent holes completed in advance of the data cut-off date) will be
included in the Q2 2010 resource update.
• Recent highlights include: 23.53 g/t gold over 12 metres, 10.20 g/t gold over 12 metres,
196.27 g/t gold over 4 metres and 24.56 g/t gold over 7 metres.
• The deposit remains open for expansion both to depth and to the west.
Masato Style Bulk Tonnage Gold Trend
Oromin has also completed limited additional drilling at the bulk-tonnage deposits on the
Western Side of the Corridor (see attached map). These deposits are similar to or extensions of
the two main deposits being mined at MDL’s newly commissioned Sabodala Mine, which
reports 3.5 million ounces in total resources.
• Masato: This deposit has significant oxide mineralization and offers excellent potential
to expand existing bulk-tonnage resources (1.22 M oz. Indicated and 71,000 oz.
Inferred) as it encompasses multiple parallel zones traced over 2 km on surface. It also
may have higher grade underground potential, as shown by recent drilling results:
notably 8.92 g/t gold over 9 metres; 14.12 g/t gold over 8 metres; 17.26 g/t gold over 12
metres; and 48.54 g/t gold over 2 metres. Additional deep drilling will further test this
advanced deposit’s underground potential.
• Niakafiri SE: This deposit also has significant oxide mineralization potential and
represents the southern extension of MDL’s Niakafiri Deposit (540,000 oz.) to the
north. The most recent resource calculation has outlined an initial inferred resource of
119,000 ounces at the Niakafiri SE deposit. It is coincident with an 8-km-long gold-in-
soil geochemical anomaly associated with the Masato Deposit to the north, but has only
been tested by limited drilling over a 900-metre extent and remains open for expansion
both along trend and to depth. Resource expansion drilling is planned for the second
half of 2010.
• Maki Medina: Only limited wide-spaced shallow drilling has been completed to date
over a 1.2-km extent. The most recent resource calculation has outlined an initial
inferred resource of 70,000 ounces at Maki Medina. This deposit has significant oxide
potential based on the limited drilling completed and remains open for expansion both
laterally and to depth. Resource expansion drilling is planned for Q1 of 2010.
Emerging Deposits and Priority Targets
The district-scale OJVG Sabodala Project offers excellent potential for significant new deposits,
with 4 new discoveries and 18 targets identified to date (in addition to 7 deposits listed above).
The most advanced of these, Koulouqwinde, is poised to become the newest deposit.

Koulouqwinde (formerly Cloverleaf):
• 20 new RC holes and 1 new core hole have been drilled to follow up previous
favourable results at this high-potential target. Drilling has now tested the
Koulouqwinde vein system over a strike extent of 200 metres and to a down-dip depth
of 150 metres. Koulouqwinde remains open for expansion both laterally and to depth.
Results to date suggest it will soon be categorized as the newest gold deposit, offering
both a higher grade open-pit and an underground mining opportunity for OJVG. The
objective of recent drilling is to gather sufficient drill data for inclusion in the Q2 2010
resource update.
• Significant results from recent drilling include: 14.24 g/t gold over 7 metres and 13.13
g/t gold over 3 metres, 5.89 g/t gold over 5 metres, 16.60 g/t gold over 1 metre, 41.99 g/t
gold over 1 metre and 96.45 g/t gold over 1 metre.
Kobokoto South
• Kobokoto South is part of the broad Kobokoto target area which is comprised of
multiple gold-in-soil geochemical targets within windows of a lateritic-covered plateau
measuring at least 2,500 by 3,000 metres.
• Recent trenching at Kobokoto South has confirmed near-surface oxide mineralization
similar to that occurring at the Masato, Niakafiri SE and Maki Medina Deposits (Masato
Style Bulk Tonnage deposits). Trenching highlights include: 1.25 g/t gold over 35
metres, 1.91 g/t gold over 9 metres; and 3.42 g/t gold over 5 metres. Additional
trenching and exploration drilling are planned for Q1 2010, with resource drilling to
follow in Q2 2010.
Koutouniokollo
• This newest priority target is situated south of the Golouma West, Golouma South,
Kerekounda, Kourouloulou deposits and the Koulouqwinde target within the Golouma
Style Higher Grade Gold Trend. New trenching results show potential for both bulk-
tonnage and higher grade deposits within two separate mineralized trends. Trenching
has thus far tested the 200 metre by 400 metre gold-in-soil geochemical target, which is
coincident with a topographic high within a very extensive area of lateritic cover.
• Trenching of the bulk-tonnage NE-oriented structure returned 1.45 g/t gold over 36
metres. Trenching of the higher grade NW trend returned 2.84 g/t gold over 3 metres;
16.37 g/t gold over 3 metres and 42.76 g/t gold over 3 metres. Additional trenching
through the lateritic cover along the mineralized trends is planned for Q1 2010, with
initial resource drilling to follow.
Golouma NW
• This priority target consists of a northwest-trending, shear-hosted quartz vein system
coincident with a gold-in-soil geochemical target measuring approximately 450 metres
by 100 metres. Initial drilling results include 6.66 g/t gold over 5 metres and 2.21 g/t
gold over 10 metres. More drilling is planned for Q2 2010.
Feasibility Study
The Feasibility Study being prepared by SRK Consulting and Ausenco Limited is estimated to
cost $3.2 million, exclusive of geotechnical drilling and environmental permitting costs, and is
scheduled for completion by the end of June 2010.

The upgraded study will examine mining sequences, production schedules and project
economics for the bulk-tonnage Masato Deposit and four higher-grade open-pit/underground
deposits — Golouma South, Golouma West, Kerekounda and Kourouloulou (and possibly
others) — and also include further metallurgical testwork to confirm CIL-only process
recoveries in the range of 90% to 96% for these five deposits. See our January 19/2010 news
release for further details.
