Platinum mined supply


Platinum mine supply is unusually highly concentrated, with over 70 per cent of global mine supply coming from a relatively small geographic region in South Africa. Here platinum mine supply has declined from a peak of 5.3 moz in 2006 to an estimated 4.3 moz in 2022. Globally, refined platinum mine supply has declined from 6.8 moz in 2006 to an estimated 5.0 moz in 2022.

When compared to gold and silver mine supply, platinum supply reflects its scarcity as a resource. In 2021, the mined production of silver, gold and platinum was 823 moz, 115 moz and 6 moz, respectively. Each year, a further 2 moz or so of platinum comes from mainly autocatalyst and jewellery recycling. Here we consider the dynamics and drivers of mined platinum supply only.

Where does platinum come from?

Thirty times rarer than gold, platinum occurs at very low concentrations in the Earth’s crust – it ranks as the 72nd most common out of 92 natural elements. There are only four regions in the world that have platinum mining operations of any significance and of these South Africa has the largest platinum resources, and output, by far, with 75 per cent of annual mined platinum supply coming from there. The balance comes from: Russia – 11 per cent; Zimbabwe – 8 per cent; and North America – 4 per cent. Other minor producers including China, Colombia and Finland produce the balance. Concentration of supply does bring some risks to mine supply should geopolitical or weather events, or regional operational challenges, act to impede the mining industry in specific geographies.

South Africa’s Bushveld Igneous Complex ore body dominates global platinum production. Here, over 80 per cent of the world’s economically viable platinum-bearing deposits (reserves) are located.

In addition to its rarity, platinum is not easy to extract. While over 70 per cent of all mineral extraction globally arises from surface mining, in contrast, the geology and location of the world’s platinum reserves mean that platinum mining takes place principally underground. The main exception to this is the Mogalakwena mine in South Africa which is the largest open-pit platinum mine in the world, producing some eight per cent of annual platinum mine supply.

Platinum is very rarely found in isolation, it is more commonly found alongside other metals, including the other Platinum Group Metals (PGMs) – palladium, rhodium, ruthenium, iridium and osmium – and base metals like nickel and copper and chrome, as well as gold and silver.

This means that a platinum mine produces a mix of PGMs and other metals for each ounce of platinum mined, refined and sold, at ratios that vary from mine to mine. Each commodity is priced individually by the global markets, contributing to total sales revenue, which when divided by the number of ounces produced derives a mine level basket price.  Depending on the composition of the ore that is extracted, platinum can be classed as either the primary product or a by-product metal. For example, in South Africa and Zimbabwe, platinum is mined as a primary metal, whereas in Russia platinum is produced predominantly as a by-product of nickel mining. In North America mined platinum is produced as a by-product of palladium and nickel mining. The various ratios of metals found within different ore types is known as the ‘prill split’.

Producers’ revenues are determined by both the volume of ore mined and the grade of the deposit; the higher the grade, the greater the metal content, with the prices of the commodities being mined – reflecting the composition of the ore body – also having a significant bearing. For PGM producers, platinum has historically made up ~ 60% of revenues, which has meant that the revenue leverage has typically been to the platinum price. Since 2018, price appreciation has resulted in that equation swinging in favour of a combination of palladium and rhodium, which currently account for ~70% of revenues.

Platinum is extracted, processed and purified through a complex series of physical and chemical processes, namely mining, concentrating, smelting and refining.

Platinum mine supply

Mining activity requires significant initial investment to discover and evaluate a deposit, develop a mine and produce refined metal. To make this an economically sensible decision, the revenue from the future sale of the metal minus the associated costs of running the mine (operating costs, capital expenditure, taxes, financing costs, etc.) should lead to a good return on the initial investment (many mining companies use a 15 per cent Internal Rate of Return as a benchmark). Often the time from discovery of PGMs in the ground to mine development and eventual production can take over a decade. Some of the factors that can impact mined platinum supply are detailed below:

  1. Reserve and resource limitations – how much metal remains in a deposit.
  2. Mineral economics – how much of that metal can be extracted at current commodity prices and production costs.
  3. Confident projections – Planning ten years ahead requires confidence in the future demand outlook and a stable regulatory and fiscal environment.
  4. Barriers to entry/exit – How easy is it to establish brand new operations or to shut-down or suspend existing operations.
  5. Licence to operate – This is a complex combination of social and environmental considerations.

Outlook for platinum mined supply

Mined platinum supply grew steadily up until 2005, since when it has broadly plateaued at almost 6 moz p.a. There are some prospects for future growth, but few projects of significance are being sanctioned, and most that are sanctioned are replacement production for reserve depletion elsewhere. This reflects an uncertain operating environment in South Africa, as well as investors in the platinum mining equities showing a preference for shareholder returns over production growth. Challenges facing South African mining companies include a worsening socio-economic climate leading to increased community unrest, as well as ongoing power shortages due to the problems being experienced by ESKOM, the state power utility.
