100% owned (Projects are subject to a government 10% free carried interest and net smelter royalty)

Description

Orezone's 168 km² Bomboré Project is the largest undeveloped gold deposit in Burkina Faso. Gold resources occur at surface in several zones contained within a gold-in-soil anomaly that extends virtually uninterrupted at a level of +0.1 g/t for 14 km and represents the largest gold anomaly in the country.

Approximately 80% of the total resource occurs in the top 80 m and economic pit shells that constrain the resource can reach depths of up to 200 m if the geological model proves to continue at depth.

Resources are open at depth and 90% of the drilling to date is within 60 m of surface. With 35,000 oz of gold per vertical meter (0.3 g/t cut-off) in the top 60 m of the deposit, there remains an excellent opportunity to significantly increase resources at depth.

There is potential for an open pit oxide heap leach operation as well as a large CIL operation with total capacity in excess of 9 million tonnes of ore per annum. Metallurgical testing shows that the deposit is amenable to heap leaching with indicated recoveries of 82% for oxide and 80% for transition, and 93% recoveries for CIL.

The Bomboré project is located just 85 km east of the capital city adjacent to the national paved highway. The project is in an area of low population density, and local infrastructure includes a high voltage power line nearby, access to sufficient water and a large labor force. These infrastructure advantages should translate into reduced operating and development costs.

Geology

The Bomboré shear zone represents the dominant structure in the permit area. This kilometer-thick arcuate shear zone is interpreted as a subsidiary structure to the regional Tiébéle-Dori-Markoye fault.

The Bomboré Project geology is characterized by a shear zone with mafic to intermediate metavolcanic and felsic tuff rocks intruded by ultramafic, diorite and granodiorite intrusions. Layers of graphitic meta-sediment unit occur in places.

Mineralization

All the Bomboré gold mineralization occurs within the main Bomboré shear zone and is associated with silica, sulphide and carbonate-albite-tourmaline-biotite alteration as well as arrays of quartz veins and veinlets. Gold is free and mainly associated with minor pyrite, chalcopyrite and arsenopyrite disseminations and stringers. The gold mineralization is preferentially associated with lithological contacts.

2011 Priorities

170,000 m of expansion and in-fill drilling to extend the average depth of drilling to 120 m
Completion of Preliminary Economic Assessment in Q2
NI 43-101 resource update by Q2 2012
Full Feasibility Study by Q3 2012
