Orezone Commences Deep Drilling and Metallurgical Testing at Bombore

Initial US$1.8 Million Program Underway

OTTAWA, ONTARIO--(Marketwire - April 23, 2009) - Orezone Gold Corporation (TSX:ORG) is pleased to announce an initial 2009 exploration budget of US$1.8 Million, largely for expansion drilling and metallurgical testing on its 100% owned Bombore gold project in Burkina Faso, West Africa.

A 4,500 m, 20 hole diamond drilling program in underway to test the depth potential of the deposit below the current average drilled depth of 55 m to a maximum vertical depth of 175 m. The program is being carried out in an area where the pit shell used to calculate resources is at its widest and extends to the bottom of the current drilling data. The Bombore Project hosts 0.93 Million ounces of Indicated resources and 1.78 Million ounces of Inferred resources with grades averaging approximately 0.5 gAu/t in the surface oxide zone and closer to one gram gold per tonne in the fresh rock below.

GBM Minerals Engineering Consultants Limited has been contracted to supervise a metallurgical testing program that will evaluate the potential for both heap leach and conventional milling technologies, or a combination thereof, for processing the Bombore deposit. If heap leaching proves to be viable, Orezone will launch an RC expansion drilling program to increase the oxide resources at surface. Similarly, if grinding tests of the sulphide ore are positive, there is significant potential to expand the resources at depth if the current diamond drill program indicates continuity to depths of 175 m or more.

Bombore has the potential to host a large, lower grade open pit project with very good infrastructure compared to much of West Africa. It is located 80km west of the capital city of Ouagadougou adjacent to a major national highway, and near a large water reservoir, and will have access to an international power grid in the coming years.

"While we are very enthusiastic about Bombore, it is prudent to wait for metallurgical and deep drilling results before making a major expenditure commitment," said Orezone CEO Ron Little. "Our objective is to take a second world class project in Burkina Faso to the feasibility stage" he added.

Sega Project Update: The Company is also planning to release a resource update for the Sega project by the end of the second quarter of 2009. Indicated resources at Sega currently total 446,000 ounces with a further 64,000 ounces in the Inferred category. The update will include the results of an additional 12,000 meters of RC and diamond drilling.

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.

Forward-looking statements and forward-looking information in this new release include statements with respect to the scope and timing of the drilling project and metallurgical testing for Bombore and the timing of the release of a resource update for the Sega project.

Forward-looking statements are based on certain assumptions, opinions and estimates of management at the date the statements are made, and are subject to a variety of risks and uncertainties that could cause actual events or results to differ materially from those projected in the forward-looking statements. The assumptions include that contracted parties provide goods and/or services on the agreed timeframes, that equipment necessary for the drilling program is available as scheduled, that no labour shortages or delays are incurred, that no material adverse change occurs to Orezone. 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.
