Bomboré

Orezone’s 104.5 km2 Bomboré Project is one of the largest gold resources in Burkina Faso. It has a total Indicated resource of 0.93 Moz (contained in 49.4Mt at a grade of 0.59g/t) and an Inferred resource of 1.78 Moz (contained within 91.8Mt at a grade of 0.61g/t). Orezone holds 100% interest.

The Bomboré resources occur at surface to a depth of 100 m in five zones contained within a gold-in-soil anomaly that extends virtually uninterrupted at a level of +0.1 g/t for more than 14 km and represents the largest gold anomaly in Burkina Faso. Resources are open at depth and for the most part still open along strike. Oxides continue to a depth of 40 m and there is good continuity into the fresh rock. There is potential for a large open pit operation at Bomboré with a low strip ratio.

The Bomboré Project is situated beside the main highway just 80 km east of the capital city of Ouagadougou. Infrastructure is very good in regards to access, water and labor. The area is flat with a low population density.
