DOSSIER 03 / 08, Ultra-Deep Extraction & Open-Pit Grade Reconciliation
Mining & Quarry Projects
Case Assessment
Operational mine geology under extreme conditions: ultra-deep Witwatersrand gold reefs at Mponeng (3.8 km) and Tshepong, and the great Birimian lodes of Obuasi in Ghana, environments of high stress, heat and seismicity where geological discipline directly governs safety and margin.
Services cover stope definition, reef tracking, blast-hole assay reconciliation and dilution control, plus quarry face mapping and reserve optimization for aggregate and dimension-stone operations.
Methodology
- 01Reef and orebody structural tracking (incl. Ventersdorp Contact Reef)
- 02Stope definition and grade-control modelling
- 03Blast-hole assay reconciliation, dilution held below 3.5%
- 04Underground and open-pit mapping under high thermal gradients
- 05Quarry reserve estimation and extraction sequencing
Notable Engagements
Mponeng (world's deepest gold mine), Tshepong and Obuasi gold operations; diamond operations at Cullinan, Williamson, Kimberley and Koffiefontein.
