Orezone Resources Inc.: Initial Resource Announced for Sega Project

OTTAWA, ONTARIO--(CCNMatthews - March 22, 2006) - Orezone Resources Inc. (TSX:OZN)(AMEX:OZN) is pleased to announce that a NI 43-101 compliant resource estimate has been completed for its 100% owned Sega gold project in Burkina Faso, West Africa. The resource estimate is based on exploration work up to and including June 15, 2005 and was completed by Met-Chem Canada Inc. and their independent Qualified Person, Mr. Yves Buro. Using a 0.5 g/t cutoff, indicated resources total 4,844,000 tonnes grading 1.99 g/t (310,600 ounces) and inferred resources total 1,413,000 tonnes grading 1.61 g/t (73,000 ounces). The resource estimate only encompasses the three main zones of mineralization on the Sega property, the Bakou, Gambo and RZ, all of which are located within a relatively small 2.5km2 area.

Orezone recently announced that a number of new gold zones have been identified on the Sega property (press release dated January 4th, 2006) that are not included in the resources. The most promising new zone of mineralization is Tiba 4, located 8km northeast of RZ, Bakou and Gambo, where mineralization has been defined over a strike length of 600m. Highlights included 30m grading 4.1 g/t in hole TBC686 while hole TBC652 returned 7m grading 14.1 g/t and hole TBC736 intersected 9m grading 7.4 g/t. Drilling has also continued on the RZ East extension where the zone has now been demonstrated to be continuous with the Bakou Zone. Recent drill results from RZ East included 29m grading 1.9g/t in hole RZC778 and 9m grading 2.3g/t in hole RZD020.

The resource estimate used ordinary Kriging, with ellipsoid parameters determined within each particular zone. The details of the estimation parameters can be found within the technical document which has been filed at www.sedar.com. Mr. Jeffery Ackert, Vice President, Technical Services, is the Company's Qualified Person under National Instrument 43-101.

Ron Little, President & CEO of Orezone stated, "The current resource estimate is a good start towards building sufficient resources for a heap leach operation. Based on current gold prices and operating costs for the West African region, a resource of double this size at the same grade or better is likely required to make a production decision. " He added that, "Recent drill results provide encouragement that we can achieve this goal and we are also evaluating a number of other scenarios in order to advance this project towards production."

Orezone currently has drill rigs working at each of the Sega, Bondi, Kossa and Essakane projects and partner Gold Fields has three additional rigs working at Essakane. The Company expects to be in a position to issue drilling results and updates on all of these projects in the near future.

Orezone is an emerging gold producer that has an exploration permit for Essakane, the largest gold deposit in Burkina Faso, West Africa where partner Gold Fields Limited is earning a 60 per cent interest by completing a bankable feasibility study. Orezone also has a pipeline of promising projects, all located in politically stable areas of West Africa which is 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.
