ShapshotThe Marula operation mining infrastructure includes two decline shafts, offices, stores, a concentrator plant, a chromite recovery plant, TSFs and overland ore conveyance.

The Marula Phase II project to expand and extend Marula’s life-of-mine was initiated in FY2022. During the 2023 year under review, the program to expand mining and milling by 20% was split into discrete projects — for the two mining complexes and the plant - to facilitate optimal resource allocation and funding while maintaining production targets. The R5.7 billion program will deliver a 15-year life-of-mine extension to FY2045 at 2.4 million tonnes per annum, with steady-state production expected in FY2028.

Summary:

Both the Merensky and UG2 Reefs are present at Marula, but only the UG2 Reef is currently exploited.

The Merensky Reef is located about 650 m below the surface with the UG2 Reef approximately 400 m deeper than the Merensky Reef. The Merensky Reefs occurs near the top of the Upper Critical Zone in a sequence of rocks knows as the Merensky Cycle.

The Merensky and UG2 Reefs are separated by a sequence of primarily anorthositic and noritic layered units of 400m in combined vertical thickness. The UG2 Reef is defined as the main chromitite layer, with most of the mineralisation confined to this unit, followed by a poorly mineralised pegmatoidal footwall. The Merensky Reef comprises the upper portion of a pyroxenite layer, with a chromitite stringer close to the hangingwall contact. Mineralisation peaks over the chromitite stringer and decreases into the hangingwall and footwall. The average 6E ratios show the differences between the Merensky and UG2 Reefs, particularly the high proportions of palladium and rhodium associated with the UG2 Reef at Marula.

Both mineralised horizons sub-outcrop on the Marula mining rights area and dip in a west-southwest direction at 10° to 14°. The reefs are relatively undisturbed by faults and dykes, with one prominent dolerite dyke traversing the mining area. Potholes represent most of the geological losses encountered underground, while a small dunite pipe also disrupts the reef horizons. These geological features are accounted for in the Mineral Resource and Mineral Reserve estimates as geological losses.
