Orezone Gold Corporation announces an increase in the NI 43-101 compliant gold resource estimate of its Sega Project in Burkina Faso, West Africa (see Table 1). The updated estimate incorporates an additional 8,050m of RC drilling (+10%) and 4,421m of diamond drilling (+53%). In 2009, a quality control program was also undertaken, which included re-logging all of the previous RC and DD holes to further refine and standardize the geological model. As part of this quality control program, the frequency of density determinations from core samples was increased in old and new holes, with the database now including 5,501 valid determinations (+137%). The result of this work is a geological model that is more robust and can be used in a scoping study with a higher degree of confidence than the previous 2009 geological model. This work provides the foundation for advancing the Sega Deposit to the feasibility stage for a small heap leach operation similar to the neighbouring Kalsaka Mine (less than 20km to the south) owned by Cluff Gold.

Dr. Pascal Marquis, V.P. Exploration for Orezone is a qualified
person under NI 43-101 and has overseen the resource estimate. Dr
Marquis utilized the same resource modeling techniques as those used
for the previous resource estimates that were completed by Orezone
and independently audited and validated by Met-Chem Canada Inc.. Met-
Chem did not audit nor validate the January 2010 resource estimate.

Orezone will complete a scoping study focusing on the near-surface oxide and semi-oxidized ores that represent about 50% of the total resources, including about 260,000 ounces in the Indicated category. The oxide and semi-oxidized ores exhibit heap leach recoveries of 80% or more based on a bottle-roll test results. A detailed metallurgical study, including heap leach column tests, will be completed on the oxidized, semi-oxidized and sulphide ores as part of the scoping study. The potential to continue to expand the oxide and sulphide resources at Sega is high with many untested targets in the 250km2 land package.

We are pleased with the geological continuity and the increase in resources at Sega. The success of the adjacent Kalsaka Mine confirms the significant value of this project to Orezone and its stakeholders. The results validate Orezone's ability to add additional resources through drilling and allow the company the confidence to take the deposit to the feasibility stage. stated Ron Little, President and CEO for Orezone.

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, developed, financed and sold Burkina Faso's largest deposit (Essakane) to IAMGOLD for $350M and continues to focus on developing the rest of its pipeline of advanced projects including Bombore, one of the largest 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.
