This concession was the site of the first diamond bearing kimberlite discovered in Mauritania (1999). This kimberlite is a coarse-grained tuff breccia. Discovery was based on a 300 meter diameter aeromagnetic anomaly. The pipe is covered by 1.5 meters of loose dune sand. The top 0.5 meters of the kimberlite is intensely calcreted with underlying kimberlite containing ilmenite, olivine, phlogopite as well as ultramafic nodules. A second pipe was discovered nearby. Both of these pipes are within a still larger, circular aeromagnetic anomaly indicating perhaps a common, much larger kimberlite pipe. To date, 4 kimberlite pipes have been discovered by the Rex Diamond Mining Corp., Ltd., concession holder, on this concession.
Located in the Reguibat Shield.
