Key takeaways
- A landslide at an unlicensed gold mine in Nariño, Colombia, killed 14 people on 19 October 2026, twelve of them women.
- Gold above $5,000 an ounce raises rewards for armed groups taxing mines, while safety investment in pits remains largely absent.
- In Sudan, at least 82 miners died at Al-Zaraa on 15 September 2026, and survivors say the RSF refused to help.
- ACLED finds violence by armed groups in the Sahel concentrating within 10 kilometres of artisanal mining sites.
A landslide collapsed an unlicensed open-pit gold mine in the Chambero sector of Santa Bárbara de Iscuandé, in Colombia's southwestern Nariño department, at about 8:30 a.m. on Monday 19 October 2026, El Tiempo reported. Fourteen people were killed and seven were injured, four of them critically. Twelve of the dead were women, most of them mothers who were their households' main earners, EFE reported. The area has no road access. Residents and responders used excavators to move earth, and wrapped bodies were carried in wooden canoes along the Iscuandé River.
It was the second mass-fatality mining disaster in Nariño in under three months. An August collapse in Policarpa killed 13 people, which brings the toll in the department to 27. The conditions behind these deaths are not unique to Colombia. Gold has traded above $5,000 per troy ounce this year. Artisanal mining zones in Colombia, Sudan, the Sahel and Venezuela share three features: armed groups that tax extraction, little or no safety investment, and workers with few alternatives. This analysis follows how those features connect.
What a record gold price changes
At current prices the arithmetic favours gold over the drug that financed Colombia's armed groups for decades. In May 2025 a Colombian general told El Tiempo that a kilo of coca was selling for about 5 million pesos on the Ecuadorian border, while a kilo of gold, small enough to fit in a smuggler's pocket, fetched about 426 million pesos. The gold price has risen sharply since.
That ratio helps explain why armed groups with roots in the cocaine trade, including the Gulf Clan and FARC dissident factions, are present in most of Colombia's alluvial gold mining areas, a shift traced in Crisis.Zone's earlier reporting on Colombia's illicit economies. It also changes the risk calculation for miners. Pits and tailings that were not worth working when gold traded near $1,200 an ounce can become attractive at today's prices, even when the ground is visibly unstable. In this analysis, the price lowers the level of danger that an impoverished digger or an armed syndicate is willing to accept.
Nariño: a mine in contested territory
A joint report by UNODC (United Nations Office on Drugs and Crime) and the Colombian Ministry of Mines and Energy, released in October 2026, showed alluvial gold exploitation growing 4.5% year on year in 2025 to 118,410 hectares, Reuters reported. Some 75% of that area operates without authorisation, and 45% of the total lies on the collective lands of Black communities. In 85.6% of municipalities with alluvial mining, active illegal armed organisations have a documented presence.
Nariño borders Ecuador and is disputed by rival armed groups. Groups reported to profit from mining around Iscuandé include Comandos de la Frontera and factions of the Segunda Marquetalia, former FARC (Revolutionary Armed Forces of Colombia) fighters who returned to arms after the 2016 peace accord. The Defensoría del Pueblo, Colombia's ombudsman's office, said illegal armed groups are present in the area, asked that rescue and humanitarian teams be given safe access, and urged the government to consider sending the Benkos Biojó hospital ship from Guapi.

The Sahel: violence around mining perimeters
Armed Islamist groups in the central Sahel have moved from highway banditry to systematic involvement in artisanal and small-scale mining (ASM). The groups include JNIM (Jama'at Nusrat al-Islam wal-Muslimin), an al-Qaeda affiliate, and Islamic State Sahel Province (ISSP). ACLED (the Armed Conflict Location and Event Data Project) finds that violence by armed groups increasingly concentrates within a 10-kilometre perimeter of artisanal mining sites.
Burkina Faso accounted for 75% of recorded mining-related violent incidents between January 2015 and June 2026, ACLED found. The violence has since spread: in 2025 Burkina Faso's share fell to 54%, while Mali accounted for 29% and Niger for 18%. Mining sites serve the groups in two ways. They impose zakat (a religious levy) and security fees, collected in gold dust. They also use the sites as bases. Fighters blend in with migrant miners, weapons are stored in abandoned shafts, and the groups obtain dual-use inputs such as ammonium nitrate, detonators, solar equipment and motorcycle parts. The background is set out in Crisis.Zone's reporting on jihadist financing through ASM gold.
Guinea and the coastal frontier
The gold frontier is moving south toward Senegal, Côte d'Ivoire, Ghana and Guinea. In Guinea, artisanal mining makes up 69% of national gold exports, or 49.6 tons. Much of that gold comes from the border region with Mali, which is exposed. In March a checkpoint at Yanfolila in Mali, 50 kilometres from the Guinean border, was attacked, and since May JNIM has disrupted cargo convoys on the Bamako-Kourémalé route into Guinea.
The risk, in this analysis, is that Guinea's informal mineral economy is drawn into the same pattern of taxation and basing seen further north. That outcome is not established. It depends on whether the groups can hold the transit routes, and on how far the Guinean state can maintain presence along the border.

A shared pattern, not a single cause
The collapses in Nariño and Kordofan, and the armed taxation of mining perimeters in the Sahel, have different local histories. They share a common mechanism. Gold at record prices makes dangerous ground profitable, armed groups collect rent from that ground, and state presence is too thin to impose safety rules or offer another livelihood.
Fourteen deaths at Santa Bárbara de Iscuandé, at least 82 at Al-Zaraa and the spread of violence around Sahelian mines are not evidence that gold causes conflict on its own. They show what can happen when a high-value, easily moved commodity is extracted under armed control. In this analysis, the pattern is likely to persist while prices stay high and origin goes unchecked in the market's upstream links. That is a judgement tied to current conditions. It would change if prices fell, if access and enforcement improved, or if buyers began to verify origin at the pit.
