Abstract

G010 ABSTRACT 1 KIMBERLITE DELINEATION BY SEISMIC SIDE- SCANS FROM BOREHOLES C. COSMA 1 A. WOLMARANS 2 N. ENESCU 1 Finsch mine is engaged in a resource estimation project. A critical requirement for accurate resource estimation is the determination of morphology and volume of the kimberlite pipe. Geostatistical simulation studies indicated that a total of 70 borehole pierce points would be required to estimate the volume of the Block 5 kimberlite with a 15% variance on estimate. The high cost of underground drilling forced geologists to investigate alternative means of mapping the kimberlite – country rock contact with the aim
