Lonmin
Lonmin was a South African platinum-group metals mining company, once among the world's largest primary producers of platinum. It operated mines in the Marikana area of the North West province, near Rustenburg, where mining and processing formed the core of its business. The company was listed on the London Stock Exchange and the Johannesburg Stock Exchange for most of its existence. Lonmin's operations included underground and open-pit mining, concentrating, smelting and refining of platinum-group metals for industrial and jewellery markets. The company became internationally known following the 2012 Marikana massacre, in which police shot dead 34 striking mineworkers during a wage dispute at its Marikana operations, an event that drew lasting scrutiny of labour relations and safety practices in South African mining. Lonmin faced years of financial difficulty afterwards, driven by weak platinum prices, high production costs and reputational damage. It underwent restructuring and rights issues in an attempt to remain viable. In 2019, Sibanye-Stillwater acquired Lonmin in an all-share deal, absorbing its Marikana operations into Sibanye-Stillwater's platinum-group metals portfolio. The company traces its origins to the London and Rhodesian Mining and Land Company, founded in the early twentieth century, before evolving into a focused platinum producer. Lonmin no longer exists as an independent entity, but its Marikana operations and legacy remain a significant reference point in South African mining and labour history.
