CONAKRY, Nov. 3, 2026 — Guinea’s government has announced a total ban on illegal and disorderly gold mining in the northeastern administrative region of Siguiri, under a joint statement signed by several ministers on Monday. The move targets one of West Africa’s most productive and most contested gold-mining areas. news
Why the ban was imposed
The decision follows inspection and assessment missions in recent months that found serious environmental damage from mining carried out in breach of existing rules, according to Mamadou Aliou Sow, spokesperson for the Ministry of National Defense. news
Officials say heavy machinery has destroyed soil, farmland and vegetation, while pollution and silting have affected the Niger River, the Tinkisso River and their tributaries. The government also condemned the use of dredgers, explosives, mercury, cyanide and other hazardous chemicals at mining sites. news
What is prohibited
The spokesperson reminded the public that mining is strictly forbidden in riverbeds and along riverbanks, on agricultural and grazing land, in protected areas and classified forests, and near homes and public infrastructure. news
How the ban will be enforced
The government plans a stricter enforcement regime:
- Permanent surveillance: A permanent monitoring system will be deployed across the Siguiri region, involving the armed forces, gendarmerie, police, customs and nature conservation officers. news
- Checkpoints: Inspections will cover roads, rivers and entry points to the region to stop dredgers, heavy machinery, explosives and chemicals from reaching illegal sites. news
- Identity and residency checks: Security forces will verify the identities and residency status of people at mining sites. Foreign nationals staying illegally will face legal procedures. news
- No protection for illegal operators: Citizens are barred from shielding any person or company involved in these operations. news
Local authorities, traditional and religious leaders, youth and women’s groups, and mining operators have been urged to cooperate and report illegal activity. news
A sector under pressure
The government stressed that the measures do not diminish the gold sector’s importance to the national economy. It said they aim to protect communities, preserve the environment and ensure resources are exploited under national law and sustainable development principles. news
The announcement fits a broader tightening of Guinea’s mining sector. In June 2026, Guinea banned raw gold exports to force local processing, a decision reported after President Mamadi Doumbouya’s announcement. The military-led government, in power since 2021, has sought to boost economic growth by renegotiating mining contracts, accelerating project development and increasing state earnings from the country’s natural resources. miningmxminingweekly
Siguiri’s long-running tensions
Siguiri has struggled with unregulated mining for years. A 2018 report said authorities estimated more than 20,000 illegal miners operated in the Siguiri region, and that mudslides at informal mines had killed at least four people. The region is home to AngloGold Ashanti’s open-pit gold mines and is plagued by illegal artisanal mining. news24miningweekly
Tensions have turned violent. In October 2025, Guinea charged 60 people with arson, theft and murder after a deadly riot at the privately owned Weily Mining firm in Siguiri. Analysts have also flagged governance and security risks along the border. One August 2026 analysis said weak governance of artisanal mining is among the issues Guinea must address, and that clashes over gold sites near the Mali border have recurred. channelafricaallafrica
What to watch next
Observers will be watching several things: how consistently the ban is enforced, how licensed operators and artisanal communities are affected, whether legal pathways for small-scale miners emerge, and whether river quality improves. How the new measures interact with the raw gold export ban will also matter for investors and local economies.
