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. |

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:
Elikhulu is a surface re-mining site with road access from all surface material sources to the plant. Ore is pumped (hydraulic re-mining) to the Elikhulu plant in slurry form.
Elikhulu is expected to yield approximately 60Koz of gold per annum for the initial six years of production (while treating the Kinross and Leslie/Bracken TSFs). Thereafter, while processing the Winkelhaak TSF, production is expected to be approximately 45Koz per annum for the plant’s remaining six years. These production estimates exclude an Inferred Resource of 102Koz of gold delineated in the soil material beneath the existing tailings dumps.
During the 2022 year, earthworks commenced on the pumping station in preparation of remining the Leslie/Bracken TSF. The pump station is planned to be commissioned during the second quarter of the 2023 financial year. 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 five years of the modelled life of the Elikhulu operation. From here, remining will move to the Winkelhaak TSF for the remaining six years.
