South African police have arrested nearly 1,000 undocumented miners at the Sheba Gold Mine in Barberton, Mpumalanga, in one of the country’s biggest recent operations against illegal mining.
According to DW, the week-long sweep was carried out under Operation Vala Umgodi and focused on a mine in the northeastern part of the country near the borders with Eswatini and Mozambique. Public broadcaster SABC reported that those arrested were working underground and would be charged with immigration offences and possibly illegal mining. Police said some of the detainees were likely underage.
The scale of the operation shows how entrenched illegal mining has become in South Africa. DW said the country has around 6,000 abandoned mines, many of which have become hotspots for criminal activity and gold theft. In that environment, the arrest of almost 1,000 people at a single site is not just a routine policing action; it is a sign of how large and organised the underground economy has become.
Barberton Mines, the mine owner, welcomed the arrests and said illegal mining would not be tolerated. That reaction matters because the Sheba Mine is not an abandoned site but an operational one with a long history. DW noted that it was founded in the 1880s and is among South Africa’s oldest and richest gold mines, which makes the policing challenge both economic and historical.
The government’s operation also touches on migration policy. Police said the people arrested were undocumented migrants, which means the case reaches beyond mining law into border control and labour enforcement. The mine’s location close to Eswatini and Mozambique adds to the cross-border dimension.
Illegal miners in South Africa are commonly known as zama-zamas, a Zulu phrase meaning “take a chance.” DW explained that the term covers both foreign migrants and unemployed South Africans who have turned to illegal mining after the formal sector declined. That mix makes the issue hard to police because it combines poverty, criminality and a parallel labour market.
The arrests come after a grim precedent elsewhere in the country. DW recalled a 2024 police operation near Stilfontein, southwest of Johannesburg, where officers surrounded an abandoned mine and cut off supplies to force miners out. That standoff ended months later with the discovery that dozens of miners had died.
By comparison, the Barberton operation appears to have ended with arrests rather than a prolonged siege. But the broader message is the same: South Africa is still wrestling with a shadow mining economy that moves in and out of active mine shafts and abandoned pits. The state is trying to respond with large-scale operations, but the underlying problem remains.
Police said more arrests could follow, suggesting the current tally may not be final. For now, the sweep at Sheba has become a new benchmark for the scale of illegal mining enforcement in South Africa and a reminder that some of the country’s richest mines also sit at the centre of its most persistent security problems.
