Mboumi East concession, having an area of around 50 sq km, is located around 170 km southeast of Libreville city, 2 km east of Ndjole town in Moyen-Ogooue province and on the eastern bank of Ogooue River. The concession area is well accessible from Libreville by a highway and the production and exploration sites are accessible from Ndjole town. Geologically, the Mboumi East concession falls on a Greenstone belt comprising of meta-sedimentary formations of Ndjole Supergroup belonging to Paleo-Proterozoic (2.5 to 1.6 Ga) age. The area has an ideal geological set-up for a gold deposit similar to some large gold deposits of the world and various occurrences/mineralisation of gold have been reported at the area. Since 1973, the concession area has attracted various internationally renowned agencies. Several types of regional level surveys have been done such as geological mapping, soil sampling, rock chip sampling, airborne magnetic survey etc and those surveys have given good results. ACM started its operation at Mboumi East concession in 2016 and has started carrying out detailed surveys to explore secondary as well as primary gold deposits such as detailed geological mapping, mapping of secondary gold resources covering the whole concession. So far, zones having secondary gold mineralisations have been identified in various areas and ACM has also started mining and washing. Presently, exploration is going on to find out more secondary gold zones as well as primary gold deposits.
