MINING




  • Mining is planned here using conventional open pit techniques with a carbon-in-pulp processing plant.
  • There will be four open pits.
  • The pit slopes have been engineered to industry standards of stability for the range of lithologies present Namarana, following risk management principles.
  • Grade control is affected by drilling 10 metre long vertical holes on a 10 metre by 5 metre grid.
  • Ore will be transported to the ore stockpile located one kilometre from the pit and waste is disposed of in dumps adjacent to the pit.
  • Approximately 70% of ore will be stockpiled before processing
  • The ore stockpiling facility going to be located between the pit and the process plant and its purpose is twofold.
  • Primarily, the area allows stockpiles of ore with differing oxide and sulphide mineralogy, gold grades, hardness, viscosity levels to be laid down separately
  • y. Ore is reclaimed from the stockpiles and fed into the process plant on a blended basis contributing to the efficiency of the process plant and maximising gold recovery.
  • The second function of the stockpile is to provide a reserve of ore to sustain feed when pit operations are affected by external factors such as heavy rains
