EXPLORATION DRILLING – GOLD DEPOSITS

Golouma Deposit

As announced in Oromin’s News Release of May 12, 2011 the Golouma deposit hosts a current Indicated Resource of 1.05 million ounces of gold (11.1 M tonnes at 2.94 g/t Au) and an Inferred Resource of 84,500 ounces of gold (0.95 M tonnes at 2.78 g/t Au) based on drilling to an average depth of 350 metres. Oromin has been conducting a widely spaced, deep drilling exploration program down dip of the Resource Shells utilized to estimate the current mineral resources at Golouma. The goal of this deep exploration drill program is to demonstrate that the Golouma gold mineralization extends to considerable depth below the current mineral resource estimate. Previously released results from this deep drilling program at the Golouma deposit include 5.30 g/t gold over 10 metres (423-433) in DH-961; 81.83 g/t gold over 6 metres (569-575) in DH-969; 32.05 g/t gold over 6 metres (589-595) in DH-970; and 4.81 g/t gold over 10 metres (631-642) in DH-971. The following outlines the most recent significant results from this deep drilling at the Golouma deposit:

  • 6.64 g/t gold over 13 metres (542-555) in DH-972
  • 4.49 g/t gold over 4 metres (932-936) in DH-973
  • 45.49 g/t gold over 1 metre (571-572) in DH-974
  • 4.32 g/t gold over 4 metres (730-734) in DH-975
  • 8.63 g/t gold over 2 metres (1,077-1,079) in DH-976
  • 4.61 g/t gold over 10 metres (757-767) in DH-977
  • 36.43 g/t gold over 2 metres (285-287) in DH-980 *
  • 4.56 g/t gold over 8 metres (642-650) in DH-980

* Intersection of the sub-parallel Golouma West Extension zone initially intersected in previously announced DH-971 which returned 421.4 g/t gold over 3 metres (294-297)

Previously announced results from this depth expansion drilling program at the Golouma deposit, and complete interval breakdowns for the above listed drill holes, are summarized in the accompanying appendix.

EXPLORATION DRILLING – GOLD DISCOVERIES AND TARGETS

In addition to the deep drilling program, recent and ongoing exploration drilling is also under way at a number of recent gold discoveries and targets throughout the OJVG Project area.

Two of these, Kinemba and Sekoto, are being evaluated as potential Heap Leach deposits. As announced in Oromin’s May 5, 2011 News Release, a Preliminary Economic Assessment of the Heap Leach opportunity at the OJVG Project is positive, based on an Indicated Resource of 475,500 ounces of gold (20.6 M tonnes at 0.71 g/t Au) and an Inferred Resource of 120,450 ounces of gold (7.0 M tonnes at 0.53 g/t Au) calculated from four deposits – Niakafiri Southeast, Niakafiri Southwest, Maki Medina and Kobokoto.

Kinemba Discovery

The Kinemba discovery is located approximately 5 kilometres southwest of the Golouma deposit. At Kinemba, drilling to date has intersected zones of gold mineralization along a minimum strike extent of 550 metres and locally to depths of approximately 150 metres. The following outlines the most recent significant results from the ongoing drilling at Kinemba:

  • 0.86 g/t Au over 5 metres (73-78) and 0.81 g/t Au over 11 metres (110-121) in RC-881
  • 0.64 g/t Au over 8 metres (29-37) and 1.49 g/t Au over 5 metres (55-60) in RC-882
  • 0.60 g/t Au over 11 metres (74-85) and 0.72 g/t Au over 25 metres (135-160) in RC-889

Previously announced results and complete interval breakdowns for the above listed drill holes are summarized in the accompanying appendix.

Sekoto Target

The Sekoto Target is located approximately 9 kilometres northeast of the Golouma deposit and approximately four kilometres east of the Masato deposit, which hosts Indicated Resources of 1,457,300 ounces of gold from 35.5 M tonnes at 1.28 g/t Au and Inferred Resources of 129,700 ounces of gold from 3.2 M tonnes at 1.25 g/t g Au, as announced in the May 12, 2011 Oromin News Release. Sekoto has only recently been the focus of exploration drilling as a potential Heap Leach deposit, following up on previous exploration hole RC-363 which intersected 1.15 g/t gold over 17 metres, from 170 to 186 metres. Exploration drilling has targeted oxide mineralization up-dip of the RC-363 intersection. Drill holes completed to date along a strike extent of approximately 200 metres have identified a deeper than usual oxide depth, ranging between 50 and 75 metres below surface. The following outlines the most recent significant results from the ongoing drilling at Sekoto:

  • 0.65 g/t gold over 23 metres (5-28) and 1.67 g/t gold over 18 metres (56-74) in RC-899
  • 0.84 g/t gold over 12 metres (17-29) in RC-900
  • 0.81 g/t gold over 6 metres (49-55) in RC-904
  • 0.75 g/t gold over 11 metres (11-22) in RC-903
  • 1.67 g/t gold over 5 metres (68-73) in RC-902
  • 1.29 g/t gold over 4 metres (60-64) in RC-901

A complete interval breakdown for the above listed drill holes is summarized in the accompanying appendix.

Two of the drilling targets, Koutouniokolla and Saboraya, are being evaluated as potential Golouma style carbon-in-leach (CIL) deposits, similar to those at Kourouloulou, Kerekounda and Golouma.

Koutouniokolla Discovery

The Koutouniokolla Discovery is located 3.5 kilometres southwest of the Golouma deposit, and although initially thought of as a Bulk Tonnage / Heap Leach style target is appearing more likely to be an early-stage CIL style open pit opportunity. Koutouniokolla is coincident with a gold-in-soil geochemical anomaly associated with a topographic prominence within a broad area of laterite cover. To date, drilling has successfully intersected gold mineralization over a minimum strike extent of 150 metres and to an average depth of approximately 125 metres, and remains open both along trend and to depth. The following outlines the most recent significant results from Koutouniokolla:

  • 1.54 g/t gold over 10 metres (26-36) in RC-893
  • 4.30 g/t gold over 16 metres (67-83) in RC-895
  • 1.81 g/t gold over 3 metres (23-26) in RC-896

Previously announced results and complete interval breakdowns for the above listed holes are summarized in the accompanying appendix.

Saboraya Target

The Saboraya target is very favorably located approximately mid-way between the Kerekounda and Kourouloulou gold deposits and is similarly related to dilational shear hosted quartz veining. Only limited drilling has occurred at Saboraya, thus far testing it along a minimum strike length of 150 metres and to a depth of only 100 metres below surface. Previously released results from Saboraya include 6.94 g/t gold over 4 metres in RC-860 and 8.91 g/t gold over 5 metres in RC-862. The following outlines the most recent significant results from Saboraya:

  • 3.92 g/t gold over 3 metres (31-34) in RC-909
  • 3.44 g/t gold over 23 metres (69-92) in RC-911

Previously announced results and complete interval breakdowns for the above listed drill holes are summarized in the accompanying appendix.

OUR NEWEST GOLD TARGET – MAMASATO

The newly identified Mamasato target is located approximately 4.5 kilometres north of the Golouma deposit and approximately 2 kilometres southeast of the centre of the Masato deposit. The Mamasato target is coincident with an 800 to 1,000 metre long, east-west oriented, gold-in–soil geochemical anomaly (> 100 ppb gold) with peak gold-in-soil values of 1.9 g/t, 2.0 g/t and 3.0 g/t. Prospecting and mapping of this target has identified a series of NNE and E-W oriented quartz veins and quartz vein systems within two to three sheared and altered zones of volcanic and intrusive felsic dikes and sills. Of interest to the project geologists, Mamasato strongly resembles the Golouma West portion of the Golouma Deposit, as to both visual components and structural orientation. On surface the Mamasato quartz veins range up to 5 to 7 metres width, within sheared and altered zones which individually range up to 25 to 30 metre widths. Initial rock sampling at Mamasato has returned gold values ranging from < 5 ppb gold to 36.9 g/t gold, with approximately 30% of the initial 39 samples exceeding 1.0 g/t gold, including 36.9 g/t; 12.71 g/t; 10.63 g/t; 5.14 g/t; 4.13 g/t; 3.57 g/t; 3.29 g/t and 3.17 g/t. So far, four excavator trenches have been completed over the westernmost 320 metres of the Mamasato target, for which we await assays. Visual observations suggest excellent third dimensional correlation within all four trenches across the veins and alteration zones tested.

OJVG currently has two diamond drills working at Mamasato. Nine core holes have now been completed at this new target and assay results are pending. Drilling has thus far partially tested the westernmost 360 metres of the Mamasato target, and now a current ongoing hole has stepped out an additional 300 metres to the east. Visual results from the initial drill holes at Mamasato suggest that the alteration zones and quartz veining observed at surface and in trenches continue to depth and visible gold has been observed in four of the holes completed. Mamasato is an exposed window of shear hosted quartz veining located within an area of extensive laterite cover. This laterite cap has preserved greater than normal depths of oxidized material which would be favorable for early stage CIL and Heap Leach feed. Trenching, drilling and further prospecting are ongoing at this newest OJVG gold discovery.
