The Colombian Navy, the National Army, and DIAN seized five tons of rare earth materials. Colombian security forces seized the strategic materials on March 22, 2026, in Puerto Carreño, in the department of Vichada. The shipment consisted of rare earth materials and suspected coltan, whose estimated value is 6.3 billion pesos (US$1.5 million) on the international market.
Authorities led the operation in the Casuarito sector. The National Police, the Attorney General’s Office, and DIAN, the Colombian tax and customs authority, supported the search. Units seized 125 sacks, and each sack weighed approximately 40 kilograms (88 pounds).
The National Police arrested two people during the operation and turned them over to the Attorney General’s Office, and the material is in custody of the authorities for technical verification.
Brig. Gen. Wilson Martinez Londoño said the bust weakens criminal finances along the eastern border. The operation is part of the Ayacucho Plus Joint Strategic Plan.
Why rare earth materials matter
Rare earth materials comprise 17 chemical elements critical to modern technology. Their unique magnetic properties allow manufacturers to build efficient electronic devices.
Coltan acts as a natural vessel for two precious metals. When processed, the mineral yields niobium and tantalum. Neither element occurs freely in nature. Both depend on the extraction of columbite and tantalite found in the Earth’s crust.
Tantalum enables the production of high-capacity electrical capacitors used in smartphones, tablets, and laptops. Niobium, meanwhile, withstands high temperatures and resists corrosion, making it essential for specialized equipment.
Technology experts say no modern mobile device can function without these components. Criminal networks exploit high international demand to fund their logistics operations, making control of deposits in Vichada a strategic priority for illegal mining rings.
Environmental toll in Vichada
Illegal mining causes irreversible damage to ecosystems across the Orinoquia region. Gen. Martinez stressed that these activities degrade soil and contaminate water sources. The government aims to dismantle illicit economies that fund armed groups. It also seeks to protect the region’s biodiversity.
Vichada has seen some of the country’s largest illegal mining busts. In April 2025, the Army seized 48 metric tons (105,800 pounds) of coltan in Caño Negro. Later that year, Operation Magnesio netted another 19 metric tons (41,900 pounds).
Both operations struck at the finances of Segunda Marquetalia and ELN, armed groups that rely on illegal mining to fund their operations along the Colombian-Venezuelan border.
