Elikhulu, Pan African’s flagship tailings retreatment operation, is one of the lowest-cost gold mining operations in Southern Africa.
The ore being treated at Elikhulu originated from the previously mined and metallurgically treated Kimberley Reef from the Winkelhaak, Leslie/Bracken and Kinross Mines as part of Evander Mines’ historical operations. The tailings of the treated material were deposited onto three TSFs that will be reclaimed in the following order: Kinross, Leslie/Bracken and Winkelhaak. Post their processing, these TSFs will be consolidated into a modern, single, enlarged regional Kinross tailings extension facility, thus reducing Evander Mines’ environmental footprint and associated environmental impact.
In May 2022, Pan African became the first South African mining company to successfully commission a utility-scale, grid-tied solar plant with the commissioning of Evander Mines’ solar energy plant. The plant has a capacity of 9.9MW and supplies energy to Elikhulu. |

Summary:
The ore being treated at Elikhulu originated from the previously mined and metallurgically treated Kimberley Reef from the Winkelhaak, Leslie/Bracken and Kinross Mines as part of Evander Mines’ historical operations. The tailings of the treated material were deposited onto three TSFs that will be reclaimed in the following order: Kinross, Leslie/Bracken and Winkelhaak. Post their processing, these TSFs will be consolidated into a modern, single, enlarged regional Kinross tailings extension facility, thus reducing Evander Mines’ environmental footprint and associated environmental impact.
Deposition material of historically treated metallurgical tailings from the Winkelhaak, Leslie/Bracken and Kinross Mines.
The material is confined to the deposition site of historical tailings and approximately 1m beneath the historical footprint. The ore consists of oxidised tailings containing pyrite-associated gold which was not recovered in the initial treatment process.
Summary:
A surface remining site with road access from all surface material sources to the plant. Ore is pumped (hydraulic remining) to the Elikhulu plant in slurry form.
Hydraulic mining of the Kinross tailings dam is utilised to pump material at a rate of 1.2Mt per month to Elikhulu.
The pump station at the Leslie/Bracken TSF was completed and commissioned during the 2023 reporting period. This pump station will allow for slurry from the Leslie/Bracken TSF to be moved to the Elikhulu plant at a rate of approximately 1.2mtpm. Mining of the Leslie/Bracken TSF will continue for the following four years of the modelled life of the Elikhulu operation. From here, remining will move to the Winkelhaak TSF for the remaining six years.
The design of the Elikhulu TSF involved the expansion and construction of a significant TSF deposition site between 2017 and 2019 as part of phase 1. This expansion took place concurrently with the construction of the plant and associated infrastructure. Furthermore, forming part of phase 2, the existing Kinross footprint will again be utilised once the reclamation process is completed. At present, construction activities for phase 2 of the Elikhulu TSF are being progressed and are expected to be completed and commissioned in December 2023 and January 2024, respectively.
