Orezone Appoints Chief Operating Officer

21,000m Infill/Expansion Drill Program Underway

OTTAWA, ONTARIO--(Marketwired - May 21, 2014) - Orezone Gold Corp. (TSX:ORE) is pleased to announce that it has appointed Tim Miller as Chief Operating Officer to oversee and complete its ongoing feasibility work for its 100% owned Bomboré Gold Project in Burkina Faso. Mr. Miller's background includes over 30 years of construction and management experience with major heap leach and agitated leach operations in the United States, South America and Africa. He spent many years with Glamis Gold Ltd. and Goldcorp as Vice President for their Central American Operations where he was intimately involved with the construction and development of their operations. Prior to that, he spent many years working in West Africa developing and operating heap leach operations in the Tarkwa region of Ghana. More recently Tim was CEO of Atacama Minerals until its takeover by Sirocco. He has a B.Sc. in Chemistry from University of New Mexico and an MBA from Webster University.

"We are very pleased to have such a seasoned mine builder with Tim's track record of success join us to oversee the completion of the Bomboré feasibility study and ultimately lead the project through to production," stated Ron Little, CEO for Orezone. "Mr. Miller brings a wealth of design, construction and operations experience required to grow Orezone from an explorer/developer into a mid-tier producer."

Since March 2014, Orezone has been completing all of the remaining geotechnical and metallurgical test work required to complete the feasibility study (FS) for a Phase 1 heap leach scenario at Bomboré. Kappes, Cassiday and Associates (KCA) have been performing final column leach tests, agglomeration and compacted permeability tests of the various ores with the results expected to be released in the coming weeks once the column leach residue assays are complete.

Drill Program Underway

Orezone has commenced a 21,000 m, $900,000 infill and expansion drill program designed to upgrade and expand oxide resources and improve the 2014 Preliminary Economic Assessment ("PEA") mine plan. Consisting mostly of shallow reverse circulation drilling, the program will focus essentially on the northern half (5km) of the PEA mine plan that represents the initial 3-5 years of production. Approximately 35% of the holes are within the PEA pit design shells and designed to upgrade inferred resources that were not included in the PEA. The other holes will be testing short-range extensions and gaps between various PEA pit shells with the objective to further expand resources. The company plans to update the resource model and mine plan in Q1 2015 (after the release of the FS) with results from the current 21,000 m drill program plus an additional 30,000 m of drill results that were not included in the 2013 resource model.
