Orezone positive drill results at bombore continue to confirm model








Orezone Gold Corporation (TSX:ORE - News) is pleased to announce additional positive results from its 100% owned Bombore Gold Project in Burkina Faso, West Africa. The latest results include 22 additional diamond drill holes (3,151 m) that average 1.67 g/t in the sulphide zone at an average vertical depth of 84 m. These results follow the first 18 diamond drill holes announced on January 6, 2011 that averaged 1.18 g/t at an average drill depth of 89 m. In addition, the first 48 reverse circulation (RC) holes (3,361 m) from the infill drilling program returned an average grade of 1.36 g/t, with the leach residue assays (tail assays) still pending for 42 of the 48 holes. All reported holes are from the Maga Zone located in the northern 1.5 km of the 11 km Bombore resource model, and indicate a bias towards higher average grade and narrower widths when compared to the current resource model, based on a lower cut-off of 0.5 g/t.


"The initial results from the Maga Zone are very encouraging, and indicate continuity below the portion of the deposit previously drilled, along the mineralized trend and below the current resource model," said Pascal Marquis, V.P. Exploration for Orezone.


Bombore is the largest undeveloped gold deposit in Burkina Faso with 1.6 Moz Indicated and 1.9 Moz of Inferred resources constrained within Whittle pit shells. Over 80% of the resources occur above a depth of 80 m with an average depth of drilling of only 60 m. The geological model indicates that a substantial increase in the resources could be achieved by drilling deeper. Today's results are part of a $24 million, 170,000 m drilling campaign designed to expand and upgrade the resources by as much as 60% by increasing the average depth of drilling from 60 to 120 m. Bombore has exceptional infrastructure for this part of Africa as it is located just 85 km from the capital city, adjacent to a paved highway, access to local power and available water. A Preliminary Economic Assessment is expected in Q2 2011, a Prefeasibility Study by year-end and a Full Feasibility Study for a large tonnage open pit Carbon in Leach ("CIL") operation by Q2, 2012.


Orezone has now completed 8,700 m of 35,000 m (25%) of the core drilling and 7,000 m of the 40,000 m (17%) of RC drilling it intends to complete by July 2011, a planned cut-off date for the data to be used in the next resource update due in October, 2011. One additional core rig was mobilized this week, and three more will be progressively mobilized in April, May and June, for a total of six rigs.

(1) Preliminary widths and grades as most leach residue assays are pending.


The mineralized intervals are based on a lower cut-off grade of 0.5 g/t, a minimal width of 3 m and less than two consecutive meters of dilution being included. The true width of the mineralization is equal to about 85% of the drill length intervals. The half-core samples were collected by Orezone employees using a diamond saw. The core samples from the weathered (oxide) zone were prepared in Ouagadougou by Abilab Burkina s.a.r.l. and SGS Burkina Faso s.a.r.l.. Orezone then split the sample to 1kg using Rotary Sample Dividers (RSD) and 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 LeachWell(TM) catalyst. The samples from the fresh or sulphide zone were prepared by BIGS and then split by Orezone to 100 g using the RSD with a 50 g aliquot analyzed by fire assay at Abilab.


The RC drilling samples were divided by Orezone using the RSD. A 2 kg split was prepared by Abilab and SGS, then split by Orezone to 1 kg using the RSD. A 1 kg aliquot was analyzed for leachable gold at BIGS, by bottle-roll cyanidation using LeachWell(TM). The leach residues from all samples with a leach grade in excess of 0.2 g/t were prepared by BIGS and then split by Orezone to 100 g using the RSD. A 50 g aliquot was analyzed by fire assay at Abilab.


Orezone employs a rigorous Quality Control Program (QCP) including a minimum of 10% standards, blanks and duplicates. This program was executed under the supervision of Dr. Pascal Marquis, V.P. Exploration for Orezone, who is a Qualified Person under National Instrument 43-101 and approved the technical information in this release. A complete table of results and the NI-43-101 Bombore Resource Report that describes the Bombore resource model can be found at www.orezone.com.


Orezone is a gold exploration and development company with significant gold resources in Burkina Faso and more than 15 years of operating experience in West Africa, one of the world's fastest growing gold producing regions. Orezone is focused on developing Bombore, the second largest gold deposit in the country, and its pipeline of advanced gold projects. Orezone's mission is to create wealth by discovering and developing gold resources in an efficient and responsible manner for the benefit of its shareholders and other stakeholders.
