Mineral Resources and Reserves

The Group’s Mineral Resource estimates increased by 3%, or 8.7 million ounces 6E, to 277 million ounces 6E, while Mineral Reserves increased by 8%, or 3.5 million ounces 6E to 47.8 million ounces 6E during FY2020.

The estimate at 30 June 2020 is dominated by Zimplats and Impala, which on a combined basis, contribute 73% of the total

Attributable Mineral Resources

attributable platinum ounces and 67% of the total attributable palladium ounces of the Group Mineral Resources.

Overall, the Group Mineral Reserve estimate increased by 3.5Moz 6E on an attributable basis to 47.8Moz 6E. Some 49% of the attributable platinum Mineral Reserves is located at Zimplats and a further 36% at Impala and 48% of the attributable palladium Mineral Reserves is located at Zimplats, 22% at Impala and 16% at Lac des Iles.

Mineral Reserves
Mineral Reserve sensitivity

The deeper Rustenburg Mineral Resources beyond current infrastructure investment require a real basket price of between R24 000 to R28 000 per 6E ounce (US$1 600). This suggests that future investments at Impala Rustenburg might at best be marginal under current price assumptions. Mineral Resources beyond current infrastructure investment will require a real long-term basket price in the order of R23 000 per 6E ounce (US$1 450).

Platinum Mineral Reserve and depth range for individual Implats shafts

The updated allocation of Implats’ Mineral Reserves per shaft infrastructure as at 30 June 2020 is depicted below. The range in depth below the surface and quantum relating to the infrastructure demonstrates among others the advantage at Zimplats, both from a depth and a size perspective.
