Orezone: Drilling Discovers Four New Gold Zones on Sega Project

OTTAWA, ONTARIO--(CCNMatthews - Oct. 27, 2005) -

Results include 13m grading 4.9 g/t and 19m grading 2.0 g/t in new Guibou Zone

Orezone Resources Inc. (TSX:OZN)(AMEX:OZN) is pleased to announce the results from an ongoing 17,000m drilling program being carried out on the Company's 100 per cent owned Sega gold project (Seguenega Permit) in Burkina Faso, West Africa.

The 15,000m reverse circulation ("RC") and 2,000m diamond drill core program, started in September, 2005 and is focussed on extensions to the three known zones (RZ, Bakou and Gambo) as well as drilling a number of new proximal targets. The overall objective is to build enough resources that would support a mining operation. One RC rig and one core rig will continue to drill until late December.

Highlights of the New Zones include:

- Guibou Zone: Hole GBC518 intersected 13m grading 4.9 g/t and hole GBC520 intersected 19m grading 2.0 g/t 5km northeast of the RZ/Bakou/Gambo complex. These two holes are 150m apart and further drilling along strike is underway.

- Tiba SE Zone: Hole TBC509 intersected 16m grading 2.3 g/t while hole TBC512 intersected 9m grading 4.1 g/t, 4km east of Guibou.

- Mossi Zone: Hole GRC561 intersected 24m grading 1.5 g/t 500m WSW of Gambo.

- RZ East Extension: Hole RCZ540 intersected 13m grading 3.2 g/t and hole RCZ536 intersected 34m grading 1.7 g/t to the east of previous drilling.

Ron Little, President of Orezone stated, "Many gold deposits in West Africa consist of a number lenses or zones that in aggregate, make an economic deposit and Sega is no exception to this model." He added that "Until now our drilling has been focussed on a relatively small 2.5 km2 area around the RZ/Bakou/Gambo complex. We are very encouraged that we have now identified new zones with potentially economic widths and grades along a 14km deformation corridor which stretches from Guibou to Tiba."

Samples were collected at a minimum of every 1m down the hole and analyzed using a 2kg bottle roll cyanide leach at the Abilab Laboratory in Ouagadougou, Burkina Faso, an internationally recognized laboratory. A minimum of 5% of the samples are for QA/QC, which includes pulp duplicates, coarse duplicates, standards and blanks. The program was carried out under the supervision of Jean Francois Sauvage, Exploration Manager, Pascal Marquis, VP Exploration and Jeffrey Ackert, VP Technical Services, and qualified person for Orezone.

The Company also announces the appointment of Gregory Bowes to the position of Vice President and Chief Financial Officer, replacing Douglas Perkins. The Board of Directors wishes to thank Mr. Perkins for his service and dedication to the Company since 2003 and wishes him well in his new career as the President and CEO of Gold Mines of Algeria. Mr. Bowes has been VP of Corporate Development with Orezone since 2003, has an MBA degree, and has held similar positions with other mining and engineering companies.
