Abstract
The drilling allows us to know the true underground geology through the information provided by the cores which reflect the geological formations crossed, based on those made in this kimberlite massif, several logging have been traced and allowed an in-depth study on the different kimberlite facies encountered. The different sections made it possible to make a geological correlation between the different formations crossed by taking into account the facies intersected by the survey. The vertical drilling represented on the cuts that had been carried out by MIBA for the estimation of reserves made it possible to position the additional boreholes well in order to be able to intersect the enclosing formations. These kimberlite facies were encountered, the green kimberlite facies and/or lithic kimberlite with hematite-goethite, ferruginous products; xenokimberlite facies with hematite – goethite, chalcopyrite; epiclastites with hematite, goethite, chalcopyrite and carbonate formations of the Upper Bushimayian.

Abstract: (french)
Le forage nous permette de connaître la vraie géologie souterraine à travers les informations fournies par les carottes qui elles, reflètent les formations géologiques traversées, nous basant sur ceux réalisés dans ce massif kimberlitique, plusieurs logging ont été tracés et permis de une étude approfondie sur les différents faciès kimberlitique rencontrés. Les différentes coupes ont permis de faire une corrélation géologique entre les différentes formations traversées en tenant compte des facies recoupées par le sondage. Les forages verticaux représentés sur les coupes qui avaient été réalisés par la MIBA pour l’estimation des réserves ont permis de bien positionner les sondages supplémentaires afin de pouvoir recouper les formations encaissantes. Ces faciès kimberlitiques ont été rencontrés, le faciès de kimberlite verte et/ou kimberlite lithique à hématite- goethite, produits ferrugineux; le faciès de xénokimberlite à hématite – goethite, chalcopyrite; les épiclastites à hématite, goethite, chalcopyrite ainsi que les formations carbonatées du Bushimayien supérieur.
