South Africa’s Chrome Wealth Hides a Deadly Underground Trade

When a wall of earth gave way on August 13 at an old mining pit near the informal settlement of Nkaneng, the ground swallowed a dozen people in a matter of seconds. Fourteen bodies were later recovered, most of them undocumented migrants who had been scraping a living from the rusted remnants of South Africa’s once‑glorious chrome fields.

"It happened in a flash, and the earth swallowed a dozen," recalled Lerothodi Nale, a Lesotho national who escaped the collapse and fled the scene without a passport, fearing the police would detain him. His story is a glimpse into a darker side of the country’s mineral boom.

Rustenburg sits atop the Bushveld Igneous Complex – a geological treasure chest that supplies the world’s largest share of chrome and platinum‑group metals. While giant corporations ship polished ore to factories in China and elsewhere, abandoned shafts litter the landscape, tempting desperate workers with the promise of quick cash.

For men like Nale, the abandoned pits are both opportunity and a tomb. "The disused mines are sitting graves with no geologists to confirm if rocks are still stable down there," warned metals‑governance expert Tapuwa Nhachi. South Africa’s government has pledged to seal dangerous shafts, yet thousands remain open, creating a lucrative playground for criminal syndicates.

Illegal operators favour chrome because the ore can often be reached near the surface, slashing extraction costs. Organized groups set up makeshift washing stations, equip miners with rudimentary tools – and sometimes even explosives – before sending them underground. The profit, however, ends up in the hands of those who own the equipment, the trucks, and the covert trade routes.

“At this juncture, we are held hostage by the alleged Maresha cartel, which takes 70 % of our earnings and forces us to work in unsafe mines until we repay debts,” Nale explained, describing a system that begins far beyond South Africa’s borders. Migrants from Lesotho, Zimbabwe and Mozambique are recruited by intermediaries who promise transport money and a wage that beats the poverty at home.

Once they arrive, workers are split into groups, shackled to debts, and shuffled between criminal networks that keep them underground until the ore runs out. Verifying the exact scale of these gangs is difficult, but police have repeatedly linked illegal mining to violence, weapons trafficking and money‑laundering.

For families waiting at home, the risk is unimaginable. Dineo Motho, 29, travelled 400 km from Lesotho to the gates of Marikana police station, clutching a traditional blanket and hoping her husband, Kgadi Ntuli, survived the collapse. He had left in January to earn enough to water their goats and feed their children, only to vanish into a system that rewards disappearance.

The ripple effects reach far beyond the mines. Traditional leader Mmanotshe Ramokoka warns that illegal extraction is churning up farmland, contaminating water sources and sparking clashes between communities and criminal crews. Environmental experts say the scars left by unregulated washing ponds scar the already fragile ecosystem of the North West province.

As long as poverty, unemployment and weak enforcement persist, the pipeline of vulnerable men to subterranean death will not slow down. "As soon as this batch of miners dies or gets injured, more destitute men are on the bus to replace them," migration scholar Loren Landau noted.

The tragedy at Nkaneng is a stark reminder that South Africa’s chrome riches, while fueling global industry, also nourish a hidden, deadly economy that thrives on exploitation and fear.
