The Letšeng Diamond Mine comprises two adjacent steep-sided kimberlite pipes; Main and Satellite. The results of the recent geological evaluation work undertaken by Letšeng Diamonds within the open pit of the Main Pipe have revealed more complex geology than was previously recognised. The in-pit investigations included geological mapping of recent mining exposures, logging of ahead-of-face percussion drill chips and petrography of pit floor samples. The results of these investigations have been integrated with macrodiamond production data and drill core information to establish an updated geological model of the pipe that will be used for ongoing mining (Fig.1). Different phases of kimberlite within the pit floor exposures have been identified based on features such as contrasting textures, olivine populations, groundmass mineralogies, country rock xenolith contents, degree of xenolith to kimberlite reaction as well as mantle-derived indicator mineral abundances.
