2018 - Summary
-
The second line at the DLP was commissioned at the end of 2018
-
102,592 metres of exploration drilling to strengthen metrics for the Centauro Pit expansion
-
Tests undertaken on the leaching pads confirmed additional gold content, resulting in an increase of 98.9 thousand ounces of gold as at 1 January 2018
-
The increase in resources/reserves led to a new pit design, resulting in the need to change from 2 to 1 components, resulting in an effect on costs
- Pilot project to evaluate the use of dual fuel systems for haulage equipment
- Installation of vibrating screens at the DLP Phase I
Performance Targets - 2019
- Ramp-up of the second line at the DLP
- Conclude construction of leaching pad number 13
- Continue infill drilling in the Centauro pit to re-assess pit expansion
- Drilling and exploration to continue at Centauro Deep and areas of influence
- Continue gradual conversion of haulage equipment to a dual fuel system
- Installation of tails thickener at the Dynamic Leaching Plants
