A major law-enforcement operation targeting illegal mining and related criminal activity in Gauteng has resulted in 39 arrests, with police and the South African National Defence Force seizing explosives, suspected gold-bearing material and large quantities of equipment allegedly used in illegal mining.
The operation was conducted between 14 and 20 September 2026 in and around Mohlakeng and the Randfontein Central Business District, as members of the South African Police Service and SANDF intensified operations under Operation Prosper/Karabo.
The arrests involved a range of alleged offences, including possession of explosives, possession and transportation of suspected gold-bearing material, possession of illegal mining equipment, contraventions of immigration legislation and driving under the influence of alcohol.
Among the most significant discoveries was a collection of explosive material recovered in the Mohlakeng policing precinct. Police said investigators secured the explosives and related items for further investigation and forensic processing.
The operation forms part of continuing efforts to disrupt illegal mining networks in Gauteng, where authorities have increasingly combined police resources, military support and other law-enforcement agencies in operations targeting the illegal extraction and movement of mineral resources.
39 SUSPECTS ARRESTED DURING THE WEEK-LONG OPERATION
The operation ran for seven days, from 14 September through 20 September 2026.
During that period, police and SANDF members conducted deployments in Mohlakeng and around the Randfontein CBD.
According to SAPS, a total of 39 suspects were arrested.
The arrests were not linked to one single offence.
Instead, investigators dealt with several categories of alleged criminal activity encountered during the operation.
These included the possession of explosives, possession and transportation of suspected gold-bearing material, possession of illegal mining equipment, contraventions of the Immigration Act and driving under the influence of alcohol.
The range of offences illustrates the wider law-enforcement challenges surrounding illegal mining.
Illegal mining can involve more than the physical extraction of minerals.
Authorities also investigate the movement of suspected illegally obtained material, equipment used to access underground workings, explosives and other activities that may support unlawful mining operations.
EXPLOSIVES FOUND IN MOHLAKENG
One of the most significant discoveries was made in the Mohlakeng policing precinct.
Police recovered a collection of explosive material during the operation.
The seized items included 17 explosives, 12 blasting cartridges, detonating cord, connector capped fuses, a copper connector fuse and six stock tube assemblies.
The items were secured for further investigation and forensic processing.
The recovery of explosives is particularly important to the investigation because explosive material can pose risks not only to people directly involved in illegal mining but also to nearby communities.
Illegal mining sites can be located close to residential areas, roads, businesses and other infrastructure.
The use or storage of explosive material in such environments can therefore create risks extending beyond the people directly participating in mining activity.
WHAT THE EXPLOSIVES ARE USED FOR
Explosives can be used in mining to break rock and access mineral-bearing areas.
In regulated mining operations, explosives are subject to strict controls concerning storage, transportation, handling and use.
Illegal mining operations do not necessarily operate under the same safety and regulatory controls.
That is one reason authorities treat the possession of explosives in illegal-mining environments as a serious matter.
The exact intended use of every item recovered during the operation has not been publicly established.
Police have said the explosives and associated materials were secured for investigation and forensic processing.
The evidence will therefore have to be examined before investigators can establish the circumstances surrounding possession and any potential links to specific illegal mining operations.
GOLD-BEARING MATERIAL ALSO SEIZED
Police also recovered suspected gold-bearing material during the operation.
Some suspects were arrested for allegedly possessing or transporting the material.
The investigation is expected to establish where the material originated and whether it was unlawfully extracted.
The movement of suspected gold-bearing material is an important part of illegal-mining investigations because authorities do not only focus on people physically working at mining sites.
They also seek to disrupt the networks involved in moving and processing minerals.
The material recovered during the operation will therefore form part of the evidence available to investigators.
ILLEGAL MINING EQUIPMENT CONFISCATED
Authorities also seized a substantial collection of equipment allegedly used in illegal mining.
The recovered equipment included generators, jackhammers, chisels, stampers, phendukas, water pumps, drill bits, spades, hammers, hacksaws and drills.
The range of equipment provides an indication of the different activities involved in accessing and processing mineral-bearing material.
Generators can provide electricity in locations without reliable grid power.
Jackhammers and drills can be used to break or penetrate hard surfaces.
Water pumps can be used in mining environments where water accumulates.
Other hand tools can be used in excavation and processing activities.
Police say the equipment was believed to have been used in illegal mining operations.
WHY THE RANDfontein AREA IS A FOCUS
The operation covered Mohlakeng and the Randfontein CBD, areas located within the broader West Rand mining region.
The West Rand has a long history of gold mining.
The region's mining legacy has also contributed to ongoing challenges involving abandoned or inactive mining infrastructure and illegal mining activity.
Illegal miners can enter old mine workings or operate in areas where mineral deposits remain accessible.
Authorities have increasingly focused on disrupting these operations because of the safety, environmental and criminal risks associated with them.
The latest Operation Prosper/Karabo deployment is part of that continuing effort.
OPERATION PROSPER/KARABO
The operation was conducted under the banner of Operation Prosper/Karabo, a law-enforcement initiative targeting illegal mining and related criminal activities in Gauteng.
SAPS worked alongside SANDF members during the latest deployment.
The use of multiple agencies reflects the scale and complexity of illegal mining.
Police officers have responsibilities involving arrests, investigations, crime prevention and evidence gathering.
The SANDF can provide additional operational support in areas where authorities are conducting large-scale interventions.
The combined approach allows authorities to deploy more personnel and resources across targeted areas.
THE OPERATION TARGETED MORE THAN MINING
Although illegal mining was the central focus, police also encountered other alleged offences.
The 39 arrests included cases involving immigration violations and driving under the influence of alcohol.
This means the operation also functioned as a broader crime-prevention and law-enforcement deployment.
Such operations can identify offences that might otherwise be dealt with separately.
The presence of officers in targeted areas allows authorities to conduct searches, stop vehicles, verify documentation and respond to information gathered during the operation.
That can result in arrests unrelated to the primary target of the deployment.
SUSPECTED GOLD MOVEMENT UNDER INVESTIGATION
The recovery of suspected gold-bearing material raises another important part of the illegal-mining economy.
Illegal mining does not end when mineral-bearing material is removed from the ground.
The material must eventually be transported, processed or sold.
Authorities therefore seek to disrupt the movement of suspected illicit minerals as part of broader efforts to weaken illegal mining networks.
In the latest operation, some arrests were linked specifically to the possession and transportation of suspected gold-bearing material.
Investigators will now need to establish the source of the material and whether the suspects were directly involved in illegal mining or were allegedly participating in another part of the supply chain.
THE ROLE OF FORENSIC INVESTIGATION
The explosives recovered during the operation have been secured for forensic processing.
Forensic examination can help investigators establish the nature of seized materials and potentially determine whether specific items are connected to other evidence or investigations.
The same principle applies to suspected gold-bearing material and equipment.
Investigators can document seized items, examine them and compare information with existing intelligence or evidence.
The process can take time, particularly when several suspects and different categories of evidence are involved.
WHY EXPLOSIVES CREATE A PUBLIC-SAFETY RISK
Illegal mining operations can present dangers beyond financial and environmental concerns.
Explosives stored or handled outside regulated systems can create risks of accidental detonation.
Mining equipment can also create physical hazards for people entering abandoned shafts or underground workings.
Some illegal mining areas may be unstable, poorly ventilated or vulnerable to flooding.
Authorities have repeatedly warned about the dangers associated with illegal mining, particularly where people operate without the safety systems found in regulated mines.
The latest seizure of explosive materials therefore has implications beyond the criminal charges facing individual suspects.
THE EQUIPMENT TELLS PART OF THE STORY
The diversity of equipment recovered during the operation also highlights how organised illegal mining can become.
A small-scale illegal mining operation may involve simple hand tools.
Larger operations can require generators, pumps, drills and machinery capable of moving and processing significant quantities of material.
The presence of several categories of equipment does not by itself establish the scale of a particular operation.
However, police believe the items recovered during the latest operation were being used in illegal mining activities.
Investigators will determine which suspects were allegedly connected to which equipment.
POLICE SAY OPERATIONS WILL CONTINUE
SAPS said illegal mining remains a threat to communities, the environment and public safety.
Authorities have indicated that joint operations with other law-enforcement partners will continue.
The latest arrests therefore form part of a continuing enforcement programme rather than a single isolated raid.
Police have also urged communities to report suspected illegal mining activities and the possession or transportation of suspected illicit goods.
Information from members of the public can assist investigators in identifying locations, vehicles, equipment and individuals allegedly involved in illegal activities.
THE ENVIRONMENTAL DIMENSION
Illegal mining can also have environmental consequences.
Mining can disturb land, affect water systems and leave behind contaminated or unstable areas.
Where old mining infrastructure is accessed without proper controls, there can also be risks involving polluted water, exposed underground workings and damaged land.
The environmental effects can continue even after illegal mining activity stops.
That is why law-enforcement operations are often accompanied by calls for broader intervention involving environmental authorities and mining regulators.
The criminal investigation is one part of a much larger problem.
COMMUNITIES LIVING NEAR MINING AREAS
Residents living near illegal mining areas can experience the consequences directly.
Noise from machinery can disrupt communities.
Heavy vehicles may move through residential areas.
The presence of explosives creates additional safety concerns.
There can also be fears about criminal activity associated with illegal mining networks.
Authorities have therefore framed illegal mining not only as a violation of mining laws but also as a community-safety issue.
The latest operation in Mohlakeng and Randfontein reflects that broader approach.
THE ECONOMIC SIDE OF ILLEGAL MINING
Gold remains a valuable commodity.
Illegal extraction can deprive legitimate operators and the state of revenue while creating an underground economy that operates outside regulatory structures.
The financial value of suspected gold-bearing material can also create incentives for organised networks.
Those networks may involve people performing the physical extraction, others transporting material and additional individuals involved in processing or selling it.
Law-enforcement agencies therefore increasingly focus on disrupting the entire chain.
Recovering equipment and suspected mineral products can provide investigators with evidence about how an operation functions.
WHY 39 ARRESTS MATTER TO THE INVESTIGATION
The number of arrests gives authorities a significant number of suspects to investigate.
However, an arrest does not automatically mean that every person will face the same charges or that every allegation will ultimately result in a conviction.
Each suspect's circumstances must be assessed individually.
Investigators must establish what each person was allegedly doing, what evidence was recovered and which laws may have been contravened.
The prosecution will then determine what charges are appropriate.
THE IMMIGRATION OFFENCES
Some of the arrests involved alleged contraventions of the Immigration Act.
Illegal mining areas can attract people from different parts of South Africa and other countries because of the potential income associated with informal mineral extraction.
Where foreign nationals are involved, immigration status can become an additional law-enforcement issue.
However, immigration status and involvement in illegal mining are separate legal questions.
A person must not be treated as an illegal miner merely because they are a foreign national.
The charges against each suspect will depend on the evidence and the specific offence alleged.
DUI ARRESTS DURING THE OPERATION
The operation also resulted in arrests for allegedly driving under the influence of alcohol.
This demonstrates how broad policing operations can uncover unrelated public-safety offences.
Driving under the influence creates risks for road users and communities.
Police can identify such offences through road checks and other enforcement activities conducted during broader operations.
The inclusion of DUI arrests in the latest operation shows that Operation Prosper/Karabo involved multiple forms of law enforcement rather than only searches of mining sites.
WHAT HAPPENS TO THE SEIZED EQUIPMENT
The seized equipment will form part of the investigation.
Some items may be examined for forensic evidence.
Others may be retained as exhibits if prosecutors determine that they are relevant to criminal charges.
The final disposition of seized equipment will depend on the legal proceedings and applicable procedures.
Authorities may also need to determine whether certain equipment can be linked to particular mining locations or suspects.
THE IMPORTANCE OF DOCUMENTING EVIDENCE
In a large operation involving dozens of arrests and numerous categories of seized property, evidence management becomes critical.
Police must record where each item was recovered, who allegedly possessed it and the circumstances surrounding the seizure.
Explosives require particularly careful handling.
Suspected gold-bearing material must also be documented and assessed.
The quality of evidence handling can affect later court proceedings.
COURT PROCEEDINGS WILL FOLLOW
The 39 suspects now face the criminal-justice process.
Those accused of specific offences are expected to appear before the appropriate courts as their cases are processed.
The exact charges and court dates may differ from one suspect to another because the arrests involve different alleged offences.
The court process will determine the legal consequences for each accused person.
Until convictions are secured, the suspects remain accused persons and are entitled to due process.
ILLEGAL MINING REMAINS A NATIONAL CHALLENGE
Although the latest operation occurred in Gauteng, illegal mining is not confined to one province.
Gold-bearing areas across South Africa have experienced illegal mining activity.
The problem has required cooperation between police, the SANDF, mining authorities, municipalities and other government structures.
The scale of the challenge means that arrests alone cannot resolve the underlying issue.
Authorities also have to address abandoned mining infrastructure, economic incentives, environmental rehabilitation and the legal processing of mineral resources.
THE WEST RAND'S MINING LEGACY
The West Rand's history is closely tied to South Africa's gold-mining industry.
For generations, mining has contributed to employment, industrial development and economic activity in the region.
But as some mines have closed or become inactive, old infrastructure has remained.
Those abandoned areas can become vulnerable to illegal access.
The authorities therefore face the challenge of securing old workings while preventing criminal exploitation of remaining mineral resources.
THE ROLE OF THE SANDF
The SANDF's involvement demonstrates the scale of resources being deployed against illegal mining.
Military personnel can support police operations by providing additional personnel and operational capabilities.
However, policing functions remain governed by the legal framework applicable to law enforcement.
The latest operation shows the continued use of joint deployments in areas identified as requiring intensified intervention.
OPERATIONAL PRESSURE ON ILLEGAL MINING NETWORKS
Repeated operations can place pressure on illegal mining networks by disrupting access to equipment, explosives and suspected mineral products.
The seizure of machinery can also make it more difficult for operators to continue activities in targeted locations.
However, illegal mining networks can adapt.
That is why intelligence gathering and investigations into the people financing, organising and profiting from illegal mining are important.
The latest operation provides investigators with new evidence and suspects that could potentially help reveal wider connections.
THE NEXT PHASE OF THE INVESTIGATION
The arrests mark the beginning of the next phase.
Investigators will examine the seized equipment and materials.
They will identify which suspects are allegedly connected to particular offences.
They will process forensic evidence.
They will prepare case dockets for prosecution.
And they will determine whether additional investigations are necessary.
If evidence establishes connections to wider illegal-mining networks, further arrests could follow.
At this stage, such developments cannot be assumed.
WHAT POLICE ARE ASKING FROM COMMUNITIES
SAPS has urged members of the public to report suspected illegal mining activities.
Community information can be particularly important because residents may notice unusual vehicle movements, heavy machinery, suspicious digging activity or the transportation of suspected mineral products.
Authorities have also encouraged people to report the possession or movement of suspected illicit goods.
Information can be provided through established police reporting channels.
The objective is to give investigators information that can be assessed alongside intelligence and evidence gathered through police operations.
A WEEK OF INTENSIFIED ENFORCEMENT
The seven-day operation demonstrates sustained law-enforcement pressure in the targeted areas.
Rather than conducting a single short raid, authorities maintained deployments from 14 to 20 September.
During that period, police and SANDF members targeted illegal mining-related activity in Mohlakeng and Randfontein.
The operation resulted in 39 arrests and multiple seizures.
The scale of the deployment also illustrates the resources required to address illegal mining.
FROM EXPLOSIVES TO GOLD-BEARING MATERIAL
The evidence recovered during the operation covers several parts of the alleged illegal-mining chain.
Explosives can provide access to mineral-bearing areas.
Mining equipment can facilitate extraction.
Suspected gold-bearing material represents the product being recovered.
Vehicles can be used to transport people, equipment or material.
When these elements are encountered together, investigators can examine whether they form part of connected activities.
The latest operation provides authorities with that opportunity.
NO FINAL FINDING OF GUILT
The 39 people arrested remain accused persons.
Their arrests do not establish that every person was involved in illegal mining.
Each case will be determined on its own evidence.
Police investigations must be followed by prosecutorial decisions and court proceedings.
The same principle applies to the seized equipment and materials.
Their recovery is evidence for investigation, not by itself proof of criminal liability.
THE BROADER FIGHT AGAINST ILLEGAL MINING
The latest operation highlights how South Africa's response to illegal mining has evolved toward larger, integrated operations.
Police and military personnel are being deployed together.
Investigators are targeting explosives and equipment.
Authorities are examining the movement of suspected mineral products.
Immigration offences and other crimes encountered during operations are also being addressed.
The objective is to disrupt the wider criminal environment surrounding illegal mining.
WHAT COMES NEXT FOR MOHLAKENG AND RANDFONTEIN
Authorities are expected to continue monitoring the areas targeted during the operation.
Police have indicated that joint operations will continue.
Further investigations may follow from evidence recovered during the week-long deployment.
Communities are also being encouraged to provide information about suspected illegal mining activities.
For investigators, the challenge will be to turn the seizures and arrests into evidence capable of supporting successful prosecutions where offences have been committed.
A MAJOR WEEK FOR GAUTENG LAW ENFORCEMENT
Between 14 and 20 September 2026, Gauteng police and SANDF members carried out a sustained operation against illegal mining and related crimes.
The result was 39 arrests.
Police recovered 17 explosives, 12 blasting cartridges, detonating cord, connector capped fuses, a copper connector fuse and six stock tube assemblies, along with suspected gold-bearing material and extensive mining equipment.
The equipment included generators, jackhammers, chisels, stampers, phendukas, water pumps, drill bits, spades, hammers, hacksaws and drills.
The operation demonstrates the range of resources authorities are deploying to disrupt illegal mining in Gauteng.
It also provides investigators with a substantial body of evidence to examine.
THE FOCUS NOW SHIFTS TO THE COURTS
The arrests are only the first stage of the criminal process.
Investigators must complete their work.
Prosecutors must assess the evidence.
Suspects must appear before court.
And the courts will determine the outcome of the cases.
The seriousness of the operation does not remove the requirement for due process.
Each accused person will have the right to challenge the allegations against them.
ILLEGAL MINING UNDER CONTINUED PRESSURE
The latest arrests send another clear message that authorities are continuing to target illegal mining in Gauteng.
The recovery of explosives is particularly significant because of the danger associated with unauthorised possession and use.
The seizure of mining machinery and suspected gold-bearing material also gives investigators an opportunity to examine the wider networks operating around illegal mineral extraction.
The involvement of the SANDF alongside SAPS demonstrates the continuing use of joint operations in the fight against the problem.
For communities in and around Mohlakeng and Randfontein, the immediate focus will be on whether the operation results in sustained disruption of illegal mining activity.
For investigators, the focus now turns to the evidence.
39 SUSPECTS HAVE BEEN ARRESTED, EXPLOSIVES AND ILLEGAL MINING EQUIPMENT HAVE BEEN SEIZED, AND THE INVESTIGATION INTO ALLEGED ILLEGAL MINING ACTIVITIES IN MOHLakeng AND RANDFONTEIN IS NOW MOVING INTO THE NEXT STAGE.
