Evander is a 66-year-old mine (sinking of the first shafts, Winkelhaak 1&3, began in 1956).
At Evander No. 8, work is under way on an extension to 24 Level to access the deeper 25 and 26 Levels. Construction of an extension from the No. 2 decline on 24 Level began in the first quarter of the 2022 financial year. The No. 2 decline was first built in the 1990s to extend the economic life of No. 8 shaft. The extension will provide access to the deeper levels of the orebody in the northwest, towards Rolspruit – a multi-million-ounce orebody situated at depth, which has not yet been mined as it would require sinking a brand-new shaft from surface to a depth of some 2,5 km – which would require significant capital and time.
Pan African intends to blast the development ends on 25 Level in the current financial year, and mine the first stope in the 2025 financial year. This work will extend Evander No. 8’s life for another 14 years. The plan is that, as mining at No. 8 shaft pillar tails off in around FY 2024, Evander 24 level will take over until FY 2026, and in turn will be replaced by Evander 25-26 level.
Peak funding for the 25 and 26 level extensions will be $52.1 million (ZAR 807 million), but using a gold price assumption of ZAR 882 060/kg, and at a recovered grade of 6.73 g/t, the estimated payback period from commencement of project development is five years.
This extension project will mine almost 600 000 oz. during its lifetime.
