Sibanye-Stillwater Brand Guidelines: A Gold Fields Spin-Off, Stillwater & Lonmin

Three gold mines, unbundled from Gold Fields.

Sibanye-Stillwater began as a gold company. English Wikipedia says that in 2012 Gold Fields unbundled its South African subsidiary, GFI Mining South Africa, which was renamed Sibanye Gold and took the Kloof, Driefontein and Beatrix mines with it, along with a set of support businesses; Gold Fields shareholders received one Sibanye share for each Gold Fields share they held. German Wikipedia dates the new company to November 2012 and its stock-market listing to 2013. The older parent has its own history, told in our Gold Fields guide.

Growth came quickly and mostly by acquisition. English Wikipedia lists the Cooke operations, bought from Gold One in 2013, and the Burnstone project, which came with the purchase of WitsGold in 2014. In April 2016 the company moved into platinum-group metals with an all-share offer for Aquarius Platinum, whose assets included Kroondal, Platinum Mile and half of Zimbabwe’s Mimosa mine, and it also took over the Rustenburg operations of Anglo American Platinum. German Wikipedia dates the agreement with Anglo American for three South African platinum mines to September 2015.

The step that gave the group its double-barrelled name came in the United States. Stillwater Mining Company, the Montana producer of palladium and platinum, received a takeover proposal from Sibanye Gold in December 2016; English Wikipedia says the deal was cleared by the US foreign-investment review committee in April 2017 and completed in May. On 30 August 2017, Wikipedia says, Sibanye Gold began trading as Sibanye-Stillwater and reorganised its operations into two regions, Southern Africa and the United States. German Wikipedia gives the legal name as Sibanye Gold Limited, with Sibanye-Stillwater as the name used in public.

Montana reef, Columbus smelter, a long metals list.

In Montana the group took over two mines on the J-M Reef of the Stillwater igneous complex: the Stillwater mine near Nye and the East Boulder mine near Big Timber. English Wikipedia describes the reef as the only known significant source of platinum-group metals inside the United States, traced over about 45 kilometres. Ore is upgraded to concentrate at each mine and further purified at a smelter and base-metal refinery at Columbus, which also recovers metals from spent catalytic converters shipped in by suppliers. That recycling line is now part of how the group is described: English Wikipedia calls it one of the global recyclers of a suite of metals, with interests in secondary mining.

Across the portfolio the list of metals is long. Wikipedia names platinum, palladium, rhodium, iridium and ruthenium as the platinum-group metals the group mines and refines, alongside gold, and lists nickel, chrome, copper, silver, cobalt and zinc as further products. In January 2020 the company raised its stake in DRDGOLD, the gold-tailings retreater, to 50.1%. In February 2021 it invested in Keliber, a lithium project in Finland, which Wikipedia says has been a subsidiary since 2022, with an 80% holding.

The company reports output region by region. According to its 2025 annual report, as cited by English Wikipedia, the South African PGM operations produced 1.7 million 4E ounces (platinum, palladium, rhodium and gold) and the US PGM operations 284 thousand 2E ounces (platinum and palladium). Wikipedia puts the 2025 workforce at 72,668 people, most of them in South Africa, and says the group is the largest industrial employer in the state of Montana. Its primary listing is on the Johannesburg Stock Exchange under the code SSW, previously SGL, with a New York listing as SBSW since February 2020.

Montana has also been the scene of recent labour news. Miningmx reported on 7 October 2026 that workers represented by the United Steelworkers at the Stillwater East mine and the Columbus metallurgical facility had signed a new three-year wage agreement, ending a strike first announced on 2 September. Chief executive Richard Stewart told the publication that the operation would need time to settle and rebuild momentum, and that the agreement set a path towards more mechanisation; he added that the Montana site also supports the group’s US recycling business.

How the category presents itself.

Platinum-group, nickel and zinc miners sell to refiners, carmakers, battery makers and investors rather than to shoppers, and their visual identities tend to reflect that. Corporate sites in this group often lean on deep blues, steel and slate greys and copper or bronze accents, tones that echo metal, rock and industrial plant without pointing to any single product. Wordmarks are usually short: a clipped group name, an acronym or a founding name kept through decades of mergers.

Photography does much of the work. Shaft heads, headgear against the sky, concentrators, smelters and refineries are commonly shown at scale, often from a distance and with people small in the frame, so that the size of an operation reads at a glance. Underground images, core trays and molten metal appear as texture beside portraits of employees and community members.

Information is organised by place and by metal. Many producers give each mine its own page, with location, depth, life of mine and headcount, and add explainers on what each metal is used for: platinum and palladium in autocatalysts, platinum in fuel cells, nickel and other metals in batteries, zinc in galvanised steel. Production updates, mineral resource and reserve statements, and annual integrated reports sit close to the surface of the site, because investors and analysts are a core audience.

Sustainability and community pages sit alongside the operations. Sections on tailings storage facilities, water, climate, employee housing, host communities and responsible sourcing are standard, and labour relations, strikes and land agreements form part of many of these companies’ public histories. The result is a register that is sober, data-heavy and place-specific, in which colour and typography stay restrained so that maps, tables and site photographs can carry the identity.

Lonmin, Marikana and a two-part name.

Another acquisition followed in 2019. Lonmin, the London-listed platinum producer that was incorporated in 1909 as the London and Rhodesian Mining and Land Company and was later known as Lonrho, became part of the group on 10 June 2019, according to English Wikipedia. Lonmin’s operations at Marikana, near Rustenburg in North West province, were where the Marikana events took place in August 2012; the official commission of inquiry submitted its report in March 2015, and the report was released to the public in June 2015. After the acquisition, Wikipedia says, Sibanye-Stillwater launched the Marikana Renewal process in 2020.

Descriptions of the group’s size change with each deal. After the Lonmin purchase, English Wikipedia describes the enlarged group as one of the largest primary producers of platinum and rhodium and a major recycler of spent catalytic-converter material; German Wikipedia, describing an earlier stage, called it South Africa’s largest gold producer, one of the ten largest gold producers worldwide. Both are dated snapshots of a portfolio that has kept moving, from Witwatersrand gold to the Bushveld, Montana and Finnish lithium.

The name itself records that path. It joins a South African gold company and an American palladium miner with a hyphen, and the group has kept the Stillwater name on the Montana operations it bought. For a design guide, Sibanye-Stillwater shows how a mining group built through acquisitions can carry two inherited names in one identity and organise its reporting by region and by metal. Compare it with Anglo American, whose platinum arm sold it the Rustenburg operations, and with Gold Fields, the company it was spun out of. For this guide we use a deep teal, a smelter copper and a slate grey with a geometric sans, an unofficial interpretation; no product or logo is reproduced.
