Sega Drilling Extends Gambo Zone

Results include 38 m grading 2.7 g/t and 13m grading 4.5 g/t

Orezone Resources Inc. (OZN:TSX, AMEX) is pleased to announce the latest results from a 20,000m drilling program being carried out on its 100 per cent owned Sega gold project in Burkina Faso, West Africa. The objectives of the current program are to expand resources in the Gambo, Bakou and RZ zones which all lie in a relatively small 2.5 km2 area, and to investigate a new target at Tiba, 6 km to the northeast. The Sega permit is 164 km2 in size and contains a large number of artisanal workings and coincident gold in soil anomalies that have not yet been fully tested.

The latest drilling included 22 holes to infill the existing resource on the Gambo Zone and to test its projected down plunge extension. Results included 38m grading 2.7 g/t in hole GRC186, 13m grading 4.5g/t in hole GRC190 and 21m grading 2.1g/t in hole GRC187 and confirmed that the zone is still open to the south. A further 10 holes were drilled in the recently discovered RZ Zone. Results included 13m grading 4.1 g/t in hole RZC207 and 25m grading 3.0 g/t in hole RZC228. Significant potential still exists to expand the size of the RZ discovery along strike and at depth and through drilling of a number of en echelon structures. 13 holes drilled into the Tiba zone included TBC170 which intersected 8m grading 3.7 g/t and hole TBC171 which intersected 16m grading 4.5 g/t.

Ron Little, President and CEO, stated that "At Sega we are dealing with a very large system with multiple zones of mineralization. All zones still require infill and delineation drilling and are not yet closed off. Priority will be given to the RZ zone which has higher average grades and the greatest expansion potential." He added that "We have a US $2 million budget and our goal is to aggressively drill Sega over the balance of the year in order to produce a resource calculation early in 2005."

Note: Samples were collected every 1m down the hole and analyzed using a 2kg bottle roll cyanide leach at the Transworld Laboratory in Tarkwa, Ghana, an internationally recognized laboratory. A minimum of 5% of the samples is for QA/QC, which include duplicates, triplicates, standards and blanks. The program was carried out under the supervision of Jeffrey Ackert, VP Exploration, and qualified person for Orezone.
