Keypoints:
- Tarkwa mine deploys drones to combat intrusions
- Artisanal gold mining surges with prices
- Tech, armed patrols fight growing threats
UNDER the searing afternoon sun in southwestern Ghana, three Gold Fields security workers launch a drone into the skies above the sprawling Tarkwa gold mine. Within minutes, the aircraft captures images of freshly dug trenches and pools of mercury-laced water—evidence of another illegal mining attempt.
The discovery sparks swift action. A 15-member response team, including armed police, descends on the site, seizing diesel-powered water pumps and a ‘chanfan’ gold processing unit. The wildcat miners had fled, leaving behind their tools and environmental destruction.
According to Reuters, scenes like this are becoming increasingly common as gold prices hover above $3,300 per ounce, attracting more informal mining activity and intensifying confrontations at industrial concessions across Ghana, Guinea, and Burkina Faso.
Surveillance from the sky
‘Because of the vegetation cover, if you don’t have eyes in the air, you won’t know something destructive is happening,’ said Edwin Asare, head of protection services at Tarkwa. ‘It’s like you first get eyes in the sky to help you put boots on the ground.’
The mine now spends roughly $500,000 each year on surveillance technology and security—a necessary cost as incursions rise and operations are increasingly threatened by wildcat mining.
Price boom fuels illicit activity
According to industry experts cited by Reuters, nearly 20 wildcat miners have died in confrontations at major sites since late 2024. Incidents have occurred at Newmont’s Ahafo site, AngloGold Ashanti’s Obuasi and Siguiri mines, and Nordgold’s Bissa operation.
While no mine staff have been harmed, the confrontations have led to production shutdowns lasting weeks. In response, companies are urging governments to deploy military units at high-risk mines.
The pressure on mining assets is being driven in part by soaring global demand, rising central bank gold purchases, and geopolitical uncertainty. Ulf Laessing, head of the Sahel programme at Germany’s Konrad Adenauer Foundation, warned: ‘The more the gold price rises, the more conflicts we will see between industrial and informal miners.’
Livelihood or liability?
Unregulated gold mining is both a vital income source and a growing problem. According to the UN, some 10 million people in sub-Saharan Africa depend on artisanal mining. In West Africa alone, informal mines produce about 30 percent of total gold output.
Miners like Famanson Keita in Senegal’s Kedougou region say they turned to gold to supplement farming incomes. But after corporate miners moved in, they claim promises of jobs and development went unfulfilled. ‘Many of our young people are employed in low-level, uncontracted jobs with little pay and no stability,’ said Keita.
What began as subsistence mining is now driven by syndicates using dredgers and Chinese-supplied equipment. In Mali’s Kenieba region, Reuters spoke with a wildcat operator who said more gear is being deployed as gold prices climb—though the identity of the financiers remains unclear.
National response ramps up
Ghanaian authorities have stepped up enforcement this year, raiding dozens of illegal sites and arresting hundreds of nationals and foreign operators, including Chinese nationals. Much of the gold from these sites is smuggled, depriving governments of revenue.
Marc Ummel of Swissaid told Reuters that Ghana lost over 229 metric tonnes of mostly artisanal gold to smuggling between 2019 and 2023, based on export data analysis.
Industry leaders warn that wildcat miners are now tunnelling as deep as 100 metres, damaging ore bodies and reducing the productive life of official mines.
‘We’re losing money,’ said Adama Soro, president of the West African Federation of Chambers of Mines. ‘They’re competing for the same ore.’
Tech and troops: the new frontier
Ghana’s Minerals Commission is launching an AI-powered control centre that will monitor data from 28 surveillance drones. The system also features excavator trackers and a remote shutdown function for equipment operating outside authorised zones.
Ahmed Dasana Nantogmah of Ghana’s Chamber of Mines said discussions with government in April produced ‘positive’ commitments for increased military support. However, mines may have to bear the cost—estimated at $18,000 per day per 50-man military unit.
‘Ideally, we want military presence at all operations, but we understand the need to prioritise,’ said Nantogmah.
As West African governments wrestle with informal mining’s economic and environmental toll, the battle is increasingly being fought with drones, data, and armed patrols—an airborne front in a booming, and dangerous, gold rush.
