Adamawa Region: Customs intercepts smuggled minerals.

According to the Customs Mobile Brigade in Bankim, located in the Mayo-Banyo Division, two trucks travelling from Mayo Darle were stopped and found to be transporting several tonnes of greisen. The mineral-rich rock contains up to 50 per cent cassiterite and was reportedly destined for export to Asia.

Authorities stated that the cargo belonged to a mining company but lacked the required customs documentation for circulation. The drivers, intercepted in Bankim, failed to present an export declaration or a certificate authorising the shipment of the minerals, including documentation for delivery to China.

Customs officials further described the seizure as part of ongoing operations to combat the illegal export of goods, particularly strategic mineral resources. Officials added that the interception forms part of measures aimed at enforcing trade regulations and controlling the movement of mineral resources within and beyond national borders.

Greisen, a rock formed through the hydrothermal alteration of granite, contains valuable metals such as tin (cassiterite), tungsten, molybdenum and niobium. The minerals are said to be used in industrial applications and modern technologies and are considered important to global supply chains.

According to Customs, the interception comes against the backdrop of illicit mineral trafficking, where unauthorised exploitation and export of natural resources continue to be reported. Authorities have indicated that such activities undermine regulatory frameworks governing the mining sector.

Customs services have reiterated plans to intensify surveillance at border points and along transport corridors within the country. The measures are intended to detect and prevent smuggling activities and ensure compliance with existing trade and export regulations.
