Orezone Bomboré Project Initial Resource Estimate

576,000 oz Indicated and 501,000 oz Inferred Resources

Orezone Resources Inc. (OZN:TSX, AMEX) is pleased to announce the results of a National Instrument 43-101 compliant gold resource estimate of its Bombore Project in Burkina Faso, West Africa. The estimate performed by Met-Chem Canada Inc., of Montreal, Quebec confirms a total indicated resource of 576,000 oz contained in 29.6 million tonnes (Mt) at a grade of 0.61 g/t along with inferred resources of 501,000 oz contained within 23.7 Mt at a grade of 0.66 g/t (Table 1). This resource estimate is based on reverse circulation (RC) and core drilling data compiled up to March 2007 to a depth of 60m using a 0.4 g/t lower cut off and 3.0 g/t top cut. The resources occur in five zones contained within the Bombore geochemical anomaly. This gold-in-soil anomaly overlying the resources, extends virtually uninterrupted at a level of +0.1g/t for more than 14km and represents the largest gold anomaly in Burkina Faso.

The current resource estimate was intended to establish a NI 43-101 compliant baseline to define the scope and character of the mineralization at Bombore by including a geostatistical analysis. Based on the results of this work Met-Chem concluded that Bombore represents a distinctive low-grade bulk-tonnage gold (Au) deposit and noted that “the gold mineralization is pervasive at the +0.2 g/t level”. Recently published studies on the metallogeny of Burkina Faso gold deposits specifically note that the “disseminated deposit style” represents the most favourable exploration target due to the potential size and similarities with some of the largest gold deposits in neighbouring Ghana.

Guided by the new resource models and in response to recommendations, Orezone initiated a 6,000 m core drilling program in December 2007 which will immediately be followed by a 20,000 m RC program in Q2 2008. The aim of these programs is to expand the near surface oxide resource and provide geostatistical data to support a lower cut off limit for future resource calculations.

“Our understanding of Bombore is evolving and the new models and current drilling will provide us with an opportunity to rapidly and significantly expand the gold resource at Bombore,” stated Steve King, VP, Exploration for Orezone.

Drilling on the Bombore property was supervised by M.S. (Steve) King, P. Geo., VP, 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. Analysis was completed at Abilab Burkina SARL Ouagadougou (subsidiary of ALS Laboratory group) for bottle roll (LeachWELL™) and ALS Chemex (formerly Abilab) Bamako for Fire Assay. Orezone holds a 50% interest in the project and can earn to a 100% (less a 1% net smelter royalty) by completing a feasibility study and $1M cash payment.

Orezone is an explorer and emerging gold producer whose main asset is Essakane, the largest gold deposit in Burkina Faso, West Africa. Essakane contains 4.0 Moz of indicated resources and 1.3 Moz of inferred resources at a 0.5 g/t cut off. Reserves contained within a US$500 gold price mine plan are 2.65 Moz. The deposit remains open and untested below 300 m from surface and is surrounded by several satellites deposits. Orezone 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.
