There has been a great deal of diamond artisanal activity concentrated on the triangle within the centre of the Bea Mountains permit, between Lofa Bridge, Weaju and Mano Godua. At this point major fault zones intersect the schist-belt lithologies. Much of the mining occurs in areas sourced from the mountains, suggesting primary source rocks are present within the schist-belt lithologies.
Reconnaissance and detailed stream sampling (193 samples) has been conducted throughout most of the licence and many high interest indicator mineral anomalies have been identified that warrant follow up to locate the kimberlite sources. Particular anomalies in the Mabong Valley are associated with extensive alluvial mining and based on their mineral chemistry it is clear that some of the source kimberlites will be diamondiferous.
