Overview
Reconciliation

The consolidated high-level reconciliation of total mineral resources and mineral reserves for the Implats Group of companies is shown below. These high-level variances are relatively small. Particulars of these variances in addition to depletions are illustrated in more detail in the sections by operation. Rounding of numbers may result in computational discrepancies, specifically in these high-level comparisons.

Notes

• The Impala estimate in the above table includes the contiguous Impala/RBR JV estimate
• Depletion was adjusted by global concentrator and mine call factors
• Potential impact of pillar factors was taken into account
• The larger variances can be attributed to the transfer of the Tamboti mineral rights into Two Rivers
• The Marula estimate includes the addition of UG2 mineral rights in terms of an agreement with Modikwa
• Smaller variances are mostly due to depletion and updates to the estimation models

Notes

• Depletion was adjusted by global concentrator factors
• The main change is the impact of the updated Zimplats statement that now excludes Portal 5S and allows for the increased pillar design
• The mineral reserves increased at Mimosa, Marula and Two Rivers due to the inclusion of additional areas into the mineral reserve inventory. For clarity note that previous statements did not include mineral reserves for Tamboti, however, part of the area transferred from Tamboti to Two Rivers has been converted to mineral reserves
• The attributable portion of the Impala mineral reserves is now at 96% following the recent employee share issue (ESOP) of 4%
• Smaller changes over the past few years are mostly related to depletion
