Tharisa mine overview

Tharisa Minerals is uniquely positioned as the world’s only co-producer of both PGMs and chrome concentrates. Tharisa Minerals’ core asset is the Tharisa Mine, which is situated on South Africa’s Western Limb of the Bushveld Complex – home to more than 70% of the world’s platinum and chrome resources.

The Tharisa Mine, located in the South African Bushveld Complex, the world’s largest PGM deposit, also taps into one of the world’s largest single chrome resources of 859.5 Mt.

Tharisa acknowledges that the safety of its people is critical to its success. The LTIFR for FY2020 was 0.09 (2019: 0.27) per 200 000 man hours worked. The mine achieved five years fatality free and four million fatality-free shifts.

The Tharisa Mine produced 142.1 koz of PGMs and 1.34 Mt of chrome concentrates in FY2020 and has provided FY2021 production guidance of between 155 koz and 165 koz of PGMs (on a 5PGE + Au basis) and 1.45 Mt to 1.55 Mt of chrome concentrates.

Tharisa Minerals holds a Mining Right over 5 475 ha of land near the town of Rustenburg in the North West province of South Africa. The Mining Right was granted on 19 September 2008 for an initial period of 30 years, providing access to MG Chromitite Layers, which outcrop with a strike length of approximately 5 km.

The Tharisa Mine has a remaining open pit life of 14 years with a projected. 40-year underground mining operation. The open pit is divided into the east pit and west pit, and extracts reef from five MG Chromitite Layers.

  • OPERATING COMPANIES
  • ARXO RESOURCES

    Arxo Resources has the exclusive right to sell the metallurgical grade chrome concentrate produced by Tharisa Minerals to customers in China and other international markets. It has established a strong platform with global customers in China, including stainless steel and ferrochrome producers, as well as global commodity traders.

    Arxo Resources also has a joint marketing agreement for Tharisa Minerals’ chemical grade chrome concentrate production.

    The scale of Arxo Resources’ operations allows for direct access to market and price discovery. Its established contacts with customers also directly creates an excellent platform for additional sales of third-party products.

  • ARXO LOGISTICS

    Arxo Logistics provides an integrated logistics platform that reduces the risk and costs of transporting concentrates. It manages the road transportation of Tharisa’s PGM concentrates to Impala Platinum and the long haul transportation of chrome concentrates from the Tharisa Mine and K3 UG2 chrome plant to international customers through bulk and container shipping. Exports take place via the Richards Bay Dry Bulk Terminal and the Durban container port on the South African coast.

    Arxo Logistics has a good relationship with both South Africa’s transport parastatal, Transnet, and the port authorities. Arxo Logistics has the exclusive use of the Marikana railway siding for chrome exports.

    Over 95% of the product is shipped in bulk, which is preferred by customers due to ease of handling and reduced port charges, as well as reduced levels of administration.

    The logistics arm of the Group has the necessary road and rail transport capacity, warehousing facilities and port facilities at the Richards Bay Dry Bulk Terminal and the Durban container port to manage Tharisa Minerals’ full production capacity. It also serves as a platform from which the Group can provide services to additional third-party customers.

  • ARXO METALS

    Arxo Metals owns the Challenger Plant, which is integrated into Tharisa Minerals’ Genesis Plant. The Challenger Plant is dedicated to the production of chemical and foundry grade concentrates.

    Specialty grade concentrates carry more stringent specifications and therefore fetch a higher selling price. Arxo Metals has an offtake agreement for the sale of its concentrates to customers in the chemical and foundry industries globally.

    In August 2017, Arxo Metals entered into an agreement with now Sibanye-Stillwater on the operation of its K3 UG2 chrome plant and for the sales and marketing of the UG2 chrome concentrate produced. Arxo Metals unlocks greater value from the K3 UG2 chrome plant using innovative processing already in use at our operations. Arxo Metals is also the beneficiation, research and development arm of the Group. Arxo Metals conducts extensive research into technologies and downstream beneficiation opportunities that have the potential to improve yields and recoveries at the Tharisa Mine. The creation of increased value PGM and chrome products through the expansion and optimisation of the Group’s processing operations is its core focus.

    Arxo Metals has commissioned a 1 MW DC furnace, operated by Tharisa Minerals, which produces PGM alloy, and is continuing its research work into refining processes.
