The technical study focused on exploring the scope of coltan, named Bri-Coltan located 21km of Issia.

The site has four concessions that represent an extensive 6 km long pour 1 kilometer wide. These types of mineralization called Gnaoré (GL), Koffi Kouadio (KKL), Koffi (KL1) and Koffikro (KL2), constituting deposits éluvials colluvials by wealth and places quartz cap and Nb-Ta.

Prospecting grid has tracked the presence of pegmatites while in situ the continuity of the Ta. Preliminary results allow to reverse the fragmentary whereobservations Introduction: The thickness variation of protocols of 0.10 m to 0.20 m so mineralized sofas range from 0.70 m to 2.0 m. Each well well deliver an average volume of 60 liters as bulk sample.

Analyses were entrusted to COREM Laboratory in Québec City. Samples issued retrospectively following interesting results: The rate of Tantalite is of medium reduced content greater than 55% content, on average reduced content alledged mineral deposits that have up to 400 grams per meter per year cube. The mineralization of the area is estimated at 70%.

According to the head geologist, Mr. Mathias B. Seka, recommended to obtain authorization for the semi-industrial exploitation of the Colombo-Tantalite in view of the importance of industrial concentration of the ore.
