This region lies on the eastern limb of the Bushveld Igneous Complex, a vast geological structure that contains the world’s largest reserves of PGMs. The mine exploits two primary ore bodies: the Merensky Reef and the Upper Group 2 (UG2) Reef. These reefs are relatively thin, laterally extensive layers of igneous rock containing significant concentrations of platinum, palladium, rhodium, gold, nickel, copper, and other associated minerals. The geology dictates the mining methods employed, typically narrow-reef, tabular mining.

Ownership within Implats

Marula mine is wholly owned and operated by Implats Platinum (South Africa) (Pty) Ltd, a subsidiary of Impala Platinum Holdings Limited (Implats). Implats is one of the world’s foremost PGM producers, with significant mining and refining operations in South Africa and Zimbabwe, as well as joint ventures and investments in Canada and the USA. Marula mine is one of Implats’ key South African assets, contributing a significant portion of the group’s overall PGM production. The strategic integration of Marula within the Implats value chain allows for efficient processing and refining of its concentrate at Implats’ central facilities, optimizing overall operational synergy and cost-effectiveness.

Merensky and UG2 Reefs

The Merensky Reef is renowned for its relatively consistent PGM grades and associated valuable minerals like nickel and copper. The UG2 Reef, typically found stratigraphically below the Merensky Reef, is characterized by a higher proportion of chromite and often exhibits different PGM-mineral associations. Both reefs are exploited at Marula mine, requiring different mining and processing approaches to maximize recovery. The presence of these two distinct, economically viable reefs allows for a diversified mining strategy and contributes to the mine’s overall resource base and longevity. The geological complexity and mineral variability within these reefs require sophisticated mineral processing techniques.

Mining and Processing Operations

The mining operations at Marula mine Steelpoort primarily employ conventional, hand-held drill-rig mining methods, adapted for the narrow-reef nature of the PGM deposits. This involves developing underground infrastructure, including shafts and tunnels, to access the Merensky and UG2 reefs. Once the ore is extracted, it is transported to the surface via mine hoists. On the surface, the ore undergoes a series of processing steps, starting with crushing and milling to reduce the rock into fine particles. This liberation of PGM-bearing minerals is crucial for subsequent separation.

The concentrated PGM minerals are then separated from the waste rock using froth flotation. This process uses specific chemical reagents to make the PGM particles attach to air bubbles, allowing them to float to the surface and be collected as a concentrate. This concentrate, typically containing several grams of PGMs per ton of material, is then transported to Implats’ central concentrating and smelting facilities for further refining. The entire process is managed with a strong emphasis on safety, environmental responsibility, and maximizing PGM recovery rates to ensure the mine’s economic viability and contribution to Implats’ overall production targets. Continuous improvement and technological integration are key aspects of these operations in 2026.

Underground Mining Methods

Marula mine utilizes conventional narrow-reef mining techniques. This involves establishing mining panels within the reefs, often using methods like breast stoping or shrinkage stoping, where miners work on or below the ore body. Hand-held drill rigs are used to drill holes for explosives, which are then detonated to break the ore. The broken ore is typically loaded onto conveyors or into LHD (Load-Haul-Dump) machines, which transport it to ore passes leading to the main shaft system. Support structures, ventilation, and dewatering systems are critical components of the underground operation to ensure safety and efficiency.

Concentrating Plant Operations

Once the PGM-bearing ore arrives at the surface, it enters the concentrating plant. Here, the first step is crushing, where large pieces of ore are broken down into smaller sizes using crushers. This is followed by milling, usually in mills like SAG (Semi-Autogenous Grinding) or ball mills, which further grind the ore into a fine powder, liberating the PGM minerals from the host rock. The resulting slurry then proceeds to the flotation circuit. In flotation cells, air is bubbled through the slurry containing added reagents. These reagents selectively attach to the PGM minerals, causing them to float to the surface as froth, which is collected. The tailings (waste rock) are discharged separately. The concentrate produced typically has a PGM content significantly higher than the run-of-mine ore.

Transport to Smelters

The PGM concentrate produced at Marula mine is not refined on-site. Instead, it is transported via road or rail to Implats’ central processing facilities, primarily the Impala smelter located in Springs, Gauteng Province, or potentially other affiliated facilities. This integrated approach allows for economies of scale in smelting and refining, ensuring efficient processing and recovery of the precious metals. The logistics of transporting large volumes of concentrate require careful planning and management to ensure timely delivery and minimize costs.
