Orezone Gold Corporation ( ORE : TSX ) is pleased to announce positive results from  an additional 81 holes of infill drilling at its Bomboré Gold Project in Burkina Faso, West Africa.  The goal of the 42,500m RC infill and expansion drilling program is to upgrade and expand the current near surface oxide resources in Q3 to be followed by a preliminary economic assessment of the project in Q4.  An initial comparison of the new infill results to the older geological model indicates that the depth of oxidation is about 15% greater than expected within the Maga deposit area, about 10% greater within the P8P9 deposit area, and that the average width and grade of the mineralization is broadly in line with the model.  Infill drilling has clearly defined improved continuity in discrete higher grade zones within the larger lower grade envelope.  At the NE end of the P8P9-CFU deposit a possible 2km NE extension has been identified that includes historical artisanal workings.  This area amongst others will receive more drilling in the subsequent programs.   

The Bomboré project consists of several deposits along a 9km trend with an additional 2.5km of possible extension recently identified and drill tested.  Results in this release include the final infill holes in the Maga deposit at the north end of the 9km trend. The first 85 holes were announced on April 12th, 2010.  Drilling of the 42,500m was completed on April 30, however only 67% of the samples have been prepared at the laboratory and only 35% of the samples have been analyzed to date.  Results are expected to continue into July.  

“Results to date indicate the potential for significant extensions, an increase in resource tonnage and grade along with improved continuity from section to section in the higher grade areas,” said Pascal Marquis, V.P. Exploration for Orezone.  All of these attributes will contribute to improving the project economics in the preliminary assessment.  A complete table of results can be found on the Orezone website.  Please note that a complete statistical analysis of the results has not yet been completed.

The RC drilling samples were divided by Orezone employees using Rotary Sample Dividers (RSDs). A 2kg split was prepared by Abilab Burkina s.a.r.l. (a subsidiary of ALS-Chemex) and SGS Burkina Faso s.a.r.l., and then split by Orezone to 1kg using RSDs. A 1kg aliquot was analyzed for leachable gold at BIGS Global Burkina s.a.r.l in Ouagadougou, by bottle-roll cyanidation using a LeachWellTM catalyst. Orezone employs a rigorous Quality Control Program (QCP) including a minimum of 15% 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.

The Bomboré Project is located 85km east of the capital city of Ouagadougou along a major national highway.  The deposit has a total Indicated resource of 0.93Moz (contained in 49.4Mt at a grade of 0.59g/t) and an Inferred resource of 1.78Moz (contained within 91.8Mt at a grade of 0.61g/t).  The grade of the resource is based on approximately 65,000 assay results, including about 44,000 assays from bottle-roll cyanidation extraction (not a complete extraction), therefore understating the in-situ grade of the resource.  Approximately one half of the current resource is oxidized and occurs essentially within 50m from surface.  The above mentioned drill programs are designed to upgrade and expand the oxidized resource in order to complete a preliminary assessment for a heap leach operation.  Detailed metallurgical results to date indicate average heap leach recoveries of 80%, with an average consumption of 0.25kg/t of cyanide and 6kg/t of cement.  The topography, drainage and rainfall are suitable to construct a large water reservoir without negatively impacting those down stream.  The project footprint is in an area of low population density and an international power grid is expected to be constructed in the near future.  These infrastructure advantages will translate into reduced project development and operating costs.

Orezone is a gold exploration and development company with more than 15 years experience in West Africa, one of the world’s fastest growing gold producing regions.  Orezone delineated, permitted, and developed Burkina Faso’s largest gold deposit (Essakane) before it was bought by IAMGOLD for $350M.  Orezone continues to focus on developing the rest of its pipeline of advanced gold projects including Bomboré, one of the largest undeveloped gold deposits in Burkina Faso.  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.
