(1) The overall yield of 64.28% reflects the fact that more RoM coal is bypassed to create a 30% Ash content coal sold to Eskom.

Resources are inclusive of Reserves.

Resources without security of tenure represent some 147Mt (92%) and RoM Reserves without security of tenure represent some 130Mt (90%).
