Quick figures: Morila gold mine’s reprocessing of tailings

Guidance offered was that the mine would produce between 10,000 and 10,500 ounces of gold in Q1,2021.

In January, the mine produced 3,494 ounces of gold and 3,372 ounces of gold in February. The mine remains on track to meet guidance.

It is intended to commence mining of satellite pits in mid-2021 and to enable processing of this ore, multiple capital works programmes are being undertaken at the processing plant and the tailings dam.

  • Civil works to install temporary 6MW power plant. Complete.
  • Vendor inspection of crushers and mill has commenced.
  • Projects are proceeding on budget, on schedule and incident free.

Projects at the tailings dam include:

  • Establishment of deposition compartments within the tailings dam footprint to accept tailings to allow congruent hydraulic mining and tailing deposition
  • Deposition of tailings into the tailings dam, as opposed to the Morila Pit, commenced on 25 January 2021. This is the first step towards dewatering the Morila Pit. Water levels in the Morila Pit have started to decline
  • Mechanical mining of the basal layer of tailings after hydraulic mining and prior to deposition of tailings. Some 350,000 tonnes at approximately 0.4g/t gold has already been placed on the ROM pad for treatment once comminution commences
  • Refurbishment of main drains in the tailings dam. Complete
  • Design of final TSF facility has commenced

Projects at satellite pits include:

  • N’tiola pit: dewatering completed, first pass drilling complete and announced to ASX, Resource estimate and first pass mine design nearing completion with further infill drilling underway targeting mineralisation near surface
  • Viper Pit: first pass infill and extension drilling complete, first results are now being received. Further infill drilling anticipated to be carried out
  • Domba pit: dewatering commenced to permit access to pit floor to undertake infill and extension drilling
  • Koting deposit: first pass drilling complete and announced to ASX, further infill drilling completed with all samples submitted to laboratory
  • Pit 5: infill drilling completed and announced to ASX, resource estimation and pit design in progress
  • Mining tender for Viper, N’Tiola and Koting nearing award
