Ndablama is located in the Bea-MDA property which is 100% owned by Aureus Mining Inc. through their fully owned subsidiary Bea Mountain Mining Corporation. Ndablama has been the target of long-established artisanal alluvial mining activity. Aureus commenced exploration activity on the target during 2011. Drilling at Ndablama has been conducted in three campaigns, and a total of 54 diamond drillholes for 8,337 m, and 63 trenches for 3,967m have been completed. A Phase 4 drill programme is currently under way. To date, less than 20% of the 13 kilometre gold anomaly has been tested

The general geology of Ndablama consists of mafics, in the form of amphibolite schists and gneisses, and ultramafic rocks, represented by magnetite-rich and magnetite-poor tremolite-schists. Two geological domains have been identified and are referred to as the Northern shear corridor and the pressure shadow zone and these are respectively situated on the northern and western edges of the granite batholith contact.

Gold mineralization is located within a sheared package of ultramafic and mafic rocks intercalated within a gneiss sequence overlying a granite batholith. The mineralization has a shallow westerly dip which averages 34°. Gold often occurs at sheared contact zones between ultramafic and mafic rocks that have been intruded by granitic dykes and breccias. Drilling has extended the mineralization over 650m of strike in a north-south direction, and is open in all directions.

Prominent alteration associated with mineralization include phlogopite, tremolite, chlorite and talc, with phlogopite dominating. Intense alteration and gold mineralisation occurs where magnetite is destroyed and replaced by pyrrhotite.
