Orezone Resources Inc.: Essakane Results Encouraging at Depth and Along Strike

OTTAWA, ONTARIO--(CCNMatthews - Sept. 1, 2005) - Orezone Resources Inc. (TSX:OZN)(AMEX:OZN) -

Gold Fields exercises option to complete Bankable Feasibility Study

Recent intersections include 44m grading 3.7 g/t and 65m grading 3.0g/t

Orezone Resources Inc. (TSX:OZN)(AMEX:OZN) is pleased to provide an update on progress at the Company's Essakane gold project in Burkina Faso, West Africa where an 85,000m drill program and pre-feasibility study are nearing completion. Ongoing drilling continues to confirm the robust nature of the Essakane Main Zone ("EMZ") and the potential to expand resources along strike and at depth. Recent drill results include 44m grading 3.7 g/t in hole ERC1396, 42m grading 2.7 g/t in hole ERC1249D and 10m grading 10.8 g/t in hole ERC1297.

The purpose of the current drill program is to increase the quality of the resource estimate and to expand the deposit by drilling down dip, along strike and below the EMZ where new zones of mineralization have recently been identified. Recent results from the lower zones include 22m grading 3.5 g/t in hole ERC1228, 20m grading 2.5 g/t in hole ERC 0872D and 65m grading 3.0 g/t in hole ERC1205D which bottomed in mineralization. Only a limited number of assays are available from drilling along strike. Particularly encouraging are holes ERC1391, located over 500m north of the EMZ, which intersected 9m grading 6.2 g/t and hole ERC1375, located 175m to the south, which intersected 24m grading 2.5 g/t.

There are currently three drill rigs on site. Progress in completing the resource estimate has been slowed by the inability of the assay labs to keep pace with the volume of activity in West Africa. This problem has recently been alleviated by the commissioning of two new independent labs, one in the Burkina Faso capital of Ouagadougou and the other at the Essakane site. It is anticipated that the current drill program will be completed before the end of September and that the revised resource calculation will be completed four to six weeks thereafter. A pre-feasibility study on the EMZ is being carried out in parallel with the latest drill program and will be updated when the new resource model is completed. The resource calculation and pre-feasibility results will enable Orezone and its joint venture partner, Gold Fields Limited ("GFL"), to plan the next phase of work at Essakane.

Ron Little, President of Orezone stated, "These results are very positive as they indicate the deposit remains open in all directions, particularly at depth, with an increasingly stronger vertical component." He added that, "Orezone will be very active on all fronts this fall. In addition to the new resource calculation and pre-feasibility results for Essakane, we will be releasing results of the soil geochemistry survey and initiating a drill program on our 100 per cent owned Kossa permit which is adjacent to Essakane. The Company will also be drilling on the Bondi, Sega and Bombore projects, as well as several grass roots targets, which are also 100 per cent owned by Orezone. Although Essakane may be perceived as a development project with further exploration upside, it is important to recognize that Orezone will continue to generate momentum and growth through the ongoing exploration of all our projects."

Note: RC samples were collected at a minimum of every 1m down the hole and analyzed using a 2kg bottle roll cyanide leach. Diamond drill samples were collected at a minimum of 1.5m down the hole and analyzed by 50g fire assay. Assaying was performed by SGS and Transworld at Tarkwa, Ghana and by Abilabs in Bamako, Mali. All of these labs are used by a wide range of international companies operating in West Africa. A minimum of 10% of the samples are for QA/QC, which includes duplicates, triplicates, standards and blanks. The program was carried out under the supervision of Jeffrey Ackert, VP Technical Services, and qualified person for Orezone.

GFL has earned a 50 per cent interest in the Essakane Project by spending US $8 million and has recently exercised its option to earn a 60 per cent interest by sole funding the project up to the completion of a bankable feasibility study. Orezone is currently the operator of the joint venture.
