Orezone Bomboré Drill Program Continues with Positive Results Maga core holes yield 42m at 1.4 g/t and 22.5m at 2.1 g/t New regional exploration drill targets to the south yield immediate positive results
May 31, 2012 - Orezone Gold Corporation (ORE:TSX) is pleased to announce additional positive oxide and sulphide drill results from the recently completed 215,000 m infill and expansion drill program at its 100% owned Bomboré Gold Project in Burkina Faso, West Africa. Results include 351 reverse circulation (RC) holes (21,302 m) and 126 diamond drill (DD) core holes (19,744 m) from the northern portion of the 11 km long Bomboré resource (see Table 3. below). The majority of these core results are from the northern Maga and CFU area (see Map below) which accounted for approximately 20% of the 2010 resources. All but 1,366 m of RC drilling program have now been reported and a full NI 43-101 compliant resource update is underway and expected to be released in July.
“These results confirm the more robust nature of the P8P9 and Maga areas with respect to continuity, widths and grades.” said Ron Little, CEO for Orezone. “Although the average depth of drilling has only been increased from 60 m to 120 m, significant mineralization has been intersected at depths of up to 255 m. This and the results reported to date highlights the potential to significantly expand and upgrade the Bomboré resource and improve the grade and preliminary economics of the project announced in June 2011.”
Metallurgical Test Program A metallurgical test program on the oxide and sulphide ores is now complete and a summary of the results is expected in June. Results to date indicate recoveries of +90% from oxides using a standard CIL process. The results will be integrated into the next round of Whittle pit resource modeling and will form the basis for developing a processing flow sheet, plant capacity, equipment selection and sizing and capital and operating cost estimates for the Definitive Feasibility Study (“DFS”).
Project Management Addition The Company is also pleased to announce that Mr. Claude Poulin has been hired as the Bomboré Project Manager to assist with the completion of the DFS and to transition the project team from exploration to development. Claude has more than 30 years of experience in the mining industry and holds a BSc Eng. degree and an MBA. He has considerable gold mine development and operation experience in West Africa including the Morila and Sadiola mines in Mali for Anglogold Ashanti, the Essakane mine for IAMGOLD and the Mana mine for SEMAFO in Burkina Faso.
Phase 2 Resource Expansion Drilling Further expansion and exploration drilling has continued since the completion of the 215,000 m program in March. Approximately 25,000 of core and RC drilling has been completed in the Southern region, mostly at Siga South, utilizing two core rigs and Orezone’s own RC rig. A number of new regional targets based on previous auger drilling are also being tested during this Phase 2 drilling program. The Phase 1 program included some 142 scout RC holes on auger targets, of which several have returned positive results (see Table 6 below). The follow-up RC drilling on the P17N, P16 and P8P9 (see Map below) scout drilling results has now been completed and results are expected in June and July. The follow up program will continue in a similar fashion in the Northern region, based on the auger and scout drilling results, only after the rainy season in Q4. None of the Phase 2 results will be incorporated into the July resource update.
Regional Exploration – New Discoveries In May 2012, Orezone completed a 1,185-hole (4,860 m) auger drilling program on a series of new regional targets where the assay results are expected in June. The reconnaissance mapping and prospecting program on the new Toéyoko permit to the southwest identified two promising targets on the permit. The first is P13 (see Map below), an 11 km long structure extending north onto the Bomboré permit with similar geology to that of the Siga West-Siga South deposit. This structure is associated with anomalous gold-in-soil geochemistry and with several gold workings where 11 grab and chip samples averaged 1.1 g/t (maximum of 4.0 g/t). The target has been covered by the recent auger drilling program using a 400 m by 25 m drilling pattern. The second target, P17S (see Map below), is located 1,600 m to the south of the P17 deposit that was included in the 2010 resource estimate. Grab and chip sampling of gold workings within the target area returned an average of 2.8 g/t from 13 samples of felsic intrusive material (maximum of 7.6 g/t), and an average of 1.1 g/t from 27 samples of sheared intermediate to mafic intrusive (maximum of 8.3 g/t). The Company completed three core holes on two fences 100 m apart on this target in April, all of which intersected gold mineralization in felsic intrusives hosted in sheared meta-gabbro (see Table 5. below). The uncut grade is averaging 2.9 g/t over a core length of 6.25 m (maximum of 10.2 g/t). The true width of these mineralized intervals is unknown at this stage.
The P17 deposit and the new P17S prospect are both associated with a 5 km NNE-oriented metagabbroic intrusive. Three auger fences have tested the possible strike extension of the P17S prospect. A highresolution resistivity survey is planned during the rainy season over this new target area to better constrain the geological interpretation. Pending results of this survey and further auger drilling results, the new P17S prospect may receive additional expansion drilling during Q4.

The mineralized intervals are based on a lower cut-off grade of 0.5 g/t, a minimal width of 3 m and up to a maximum of two consecutive meters of dilution being included. The true width of the mineralization is approximately 85% of the drill length intervals in Maga, P16, P17 and P8P9 areas, and 95% of the drill length intervals in the Siga area. The halfcore samples were collected by Orezone employees using a diamond saw. The core samples from the weathered (oxide) zone were prepared by Abilab Burkina s.a.r.l. (a subsidiary of ALS-Chemex), BIGS Global Burkina s.a.r.l and SGS Burkina Faso s.a.r.l., and then split by Orezone to 1 kg using Rotary Sample Dividers (RSDs). A 1 kg aliquot was analyzed for leachable gold at BIGS Global Burkina s.a.r.l in Ouagadougou, by bottle-roll cyanidation using a LeachWellTM catalyst. The samples from the fresh or sulphide zone were prepared by BIGS Global Burkina s.a.r.l, SGS Burkina Faso s.a.r.l., ACTLABS Burkina Faso s.a.r.l. and Abilab Burkina s.a.r.l. in Ouagadougou and then split by Orezone to 1 kg using

A 1 kg aliquot was analyzed for leachable gold at BIGS Global Burkina s.a.r.l in Ouagadougou, by bottle-roll cyanidation using a LeachWellTM catalyst.
The RC drilling samples were divided by Orezone employees using Rotary Sample Dividers (RSDs). A 2 kg split was prepared by Abilab Burkina s.a.r.l. (a subsidiary of ALS-Chemex), BIGS Global Burkina s.a.r.l and SGS Burkina Faso s.a.r.l., and then split by Orezone to 1 kg using RSDs. A 1 kg aliquot was analyzed for leachable gold at BIGS Global Burkina s.a.r.l in Ouagadougou, by bottle-roll cyanidation using a LeachWellTM catalyst. The leach residues from all samples with a leach grade in excess of 0.2 g/t were prepared by BIGS Global Burkina s.a.r.l. and then split by Orezone to 50 g using Rotary Sample Dividers (RSDs). A 50 g aliquot was analyzed by fire assay at Abilab Burkina s.a.r.l. (a subsidiary of ALS-Chemex) or a 30 g aliquot at SGS Burkina Faso s.a.r.l.

About Orezone Gold Corporation Orezone is a Canadian company with a gold discovery track record of +10 M oz and recent mine development experience in Burkina Faso, West Africa. Bomboré, the Company’s 100% owned flagship project, is one of the largest gold deposits in the country and is situated 85 km east of the capital city, adjacent to an international highway. Resources are constrained within optimized open pit shells that span 11 km, and include 1.6 Moz indicated (60.9 Mt @ 0.81 g/t) and 1.9 Moz inferred resources (60.6 Mt @ 0.96 g/t) with an average drill depth of only 60 meters. The Company has recently completed a 215,000 m drill program to significantly expand resources and support the completion of a DFS in 2012. Orezone’s goal is to develop Bomboré into a world-class deposit by the end of 2012 and become a mid-tier producer by 2015.
