Merensky Reef
The Mineral Resource tonnage increased by 31% to 78.1 Mt (2010: 59.6 Mt) and the 4E ounce content increased by 34% to 16.5 Moz (2010:
12.3 Moz) mainly owing to the following:
Thembelani Mine: Reallocation of previously reported Ore Reserves back to Mineral Resources owing to economic assumptions: +13.8 Mt
+3.1 Moz.
Decrease in geological loss.
UG2 Reef
The Mineral Resource tonnage decreased by 11% to 212.0 Mt (2010: 239.1 Mt) and the 4E ounce content decreased by 11% to 36.1 Moz (2010:
40.6 Moz) mainly owing to the following reasons:
Thembelani and Siphumelele mines: Conversion of Mineral Resources to Ore Reserves.
Decrease in geological loss.
