Summary:

The Marikana mining rights areas are underlain by the Merensky and UG2 Reefs over a strike length of approximately 27km. The strata and reefs strike in an approximately east-west direction and generally dip between 8°N in the west, gradually increasing to 13°N in the extreme east of the property.

The UG2 Reef normally comprises a narrow tabular chromitite layer, which varies in thickness between 1.0m and 1.4m. Localised internal waste comprising pyroxenite or anorthosite can occur which is included in the Mineral Resource. To the west of the property the Leader Chromitite layer separates from the main UG2 Chromitite creating a zone of “split facies”. This affects the far western areas of K3 and K4 and the future K5 mining blocks. The UG2 Reef underlies the Merensky Reef by between 130m and 210m, the middling between the two reefs gradually increasing across the operations from west to east The Merensky Reef varies across the Marikana operations. This variability is used to define several facies (or reef sub-types) based on the occurrence of distinct lithological units within the reef. Two major types, pegmatoidal and non-pegmatoidal facies, occur.

At the Marikana operation, the Merensky Reef varies, and this variability is used to define several facies (or reef sub-types) based on the occurrence of distinct lithological units within the reef. Two major types, pegmatoidal and nonpegmatoidal facies, occur. These have been separated further into a total of ........

Summary:

The Marikana operation is a large, established shallow to moderate depth PGM mining complex that is accessed from surface through numerous incline and vertical shaft systems. All facilities are in good condition. All the permanent infrastructure required to access and mine the LoM plan is already established and in use.

Marikana currently has five contributing shafts: 4 Belt, K3, Rowland, Saffy, and E3. The Merensky and the UG2 reefs are mined simultaneously at an average depth of 500m and are accessed via infrastructure consisting of shallow incline and deeper vertical shafts. The 4 Belt shallow incline, K3 and Rowland vertical shafts target both the Merensky Reef and UG2 Reef horizons, while the E3 shallow incline and Saffy vertical shaft target only the UG2 Reef. The vertical shaft complexes account for the largest portion of the

The Mineral Reserves are accessed from the surface using conventional underground mining methods. The 4 Belt and E3 shallow incline shafts extend to depths of approximately 400m below surface and the K3, Rowland and Saffy vertical shafts to approximately 900m below surface. 45% or 48.3Moz of the total Mineral Resources are above infrastructure (AI) and 55% or 54.9Moz are below infrastructure (BI). The main contributing factor to this being the large Mineral Resource base in the Merensky Reef that has not yet been mined.

Apart from the underground operations, there is one tailings retreatment operation. The re-minin ........
