OTTAWA, ONTARIO -- (Marketwire) -- 07/29/09 -- Orezone Gold Corporation (TSX: ORE) is pleased to announce assay results for the remaining thirteen holes of a twenty hole, 4,500m diamond drilling program on its wholly owned Bombore gold project in Burkina Faso, West Africa. The program has confirmed the continuation of the gold mineralization below the surface oxide resources (average 40m depth) to a depth of 175m. Although the program has only tested 200m of a 10km resource model, the average grade of the mineralization is slightly better than expected as compared to the projected resource model at depth. The mineralization remains open at depth and will be tested along strike in due course after completion of ongoing metallurgical studies. The Bombore Project contains 0.93 Million ounces of Indicated resources and 1.78 Million ounces of Inferred resources with grades averaging approximately 0.5 g/t in the surface oxide zone and closer to one gram of gold per tonne in the fresh rock below.

The program is being carried out in an area where the pit shell used to calculate resources is approximately 1km wide, centered on a core of mineralization roughly 300m wide. Holes have been spaced every 90m along two section lines that are 200m apart. The results from the last thirteen holes further confirmed that the fresh rock mineralization at depth (above 0.5g/t) occurs only below the core or centre of the oxide resources and grades become marginal on either periphery. This is offset by the fact that the weighted grade of the samples from the Fresh zone above a lower cut-off of 0.5 g/t is 1.10 g/t, about 24% better than predicted by the model. Table 2 shows results from the Fresh zone from the entire program. Although the oxide mineralization was more restricted than the model, the average grade of the oxide/transition material was better than expected at 0.58 g/t vs 0.52 g/t (using a 0.25 g/t cutoff).

"The results are positive but this in only small sample of such a large system", said Ron Little, President and CEO of Orezone. "The results of the ongoing detailed metallurgical work are expected in Q4 and will assist in fully evaluating the economic potential of Bombore. Our goal is to first focus on establishing the viability of the extensive surface oxide resources followed by a more detailed examination of the size and potential of the fresh rock resources at depth" he added. Bombore has the potential to host a large, lower grade open pit operation with very good infrastructure compared too much of West Africa. It is located 80km east of the capital city of Ouagadougou adjacent to a major national highway, near a large water reservoir, and will have access to an international power grid in the coming years.

Orezone is also pleased to announce the appointment of Dr. James Gill to the Board of Directors. Dr. Gill is one of Canada's most successful mining executives with almost 40 years of experience involving exploration, feasibility studies, mine finance, development and operations. He founded Aur Resources Inc. and served as President and CEO for 26 years until its acquisition by TeckCominco Ltd in August 2007 for $4.1 billion. Dr. Gill is a graduate of McGill and Carleton Universities and holds a Ph.D. in economic geology.

"We are very pleased to welcome Jim to the Board and believe his wealth of experience in the mining industry will be invaluable to the Company" said Ron Little, President and CEO of Orezone. "Jim's entrepreneurial spirit is well suited to Orezone's exploration growth and development strategies" he added. Dr. Gill's appointment remains subject to approval by the Toronto Stock Exchange.

Drilling on the Bombore property was supervised by Dr. Pascal Marquis, Vice President of Exploration for Orezone, who is a Qualified Person under National Instrument 43-101 and has reviewed and approved the technical information in this release. Orezone employs a rigorous Quality Control Program (QCP) employing a minimum 10% standards, blanks and duplicates. All core holes were entirely sampled and the half core samples collected by Orezone are averaging a length of 1 m. The sample preparation was performed by Abilab Burkina S.A.R.L., a subsidiary of ALS Chemex. Assays were completed at BIGS Global Burkina S.A.R.L. for oxide and transition material using the LeachWELL(TM) method and the fresh rock material was analyzed by SGS Burkina S.A. using Fire Assay method.

Orezone is a gold exploration and development company that owns Bombore, one of the largest gold deposits in Burkina Faso, West Africa. Orezone also has a pipeline of developing projects, all located in politically stable areas of West Africa, one of the world's fastest growing gold producing regions. Orezone's mission is to create wealth by discovering and developing the earth's resources in an efficient and responsible manner.

Factors that could cause the forward-looking statements and forward-looking information to differ materially in actuality include the failure of contracted parties to perform as contracted and the failure of equipment. The Company undertakes no obligation to update forward-looking statements if circumstances or management's estimates or opinions should change. The reader is cautioned not to place undue reliance on forward-looking statements.

Readers are advised that National Instrument 43-101 of the Canadian Securities Administrators requires that each category of mineral reserves and mineral resources be reported separately.
