The Price of Progress: The Dark Side of Critical Minerals in the Amazon

On the Colombian-Venezuelan border, Chinese buyers, Colombian guerrillas, corrupt state forces, and Indigenous communities are locked in violent competition over materials at the center of 21st century geopolitical rivalries. The global energy transition, combined with increasing defense budgets and technological development, has created unprecedented demand for rare earth elements and critical minerals. These are essential components for electric vehicle batteries, wind turbines, solar panels, and defense and aerospace systems such as missiles, armor-piercing ammunition, night-vision devices, and aircraft engines.

In Colombia’s jungles, where the deep green of the Amazon collides with poverty and exclusion, a hidden and dangerous business flourishes. In the remote corners of Guainía, Indigenous communities such as the Puinave find themselves trapped in illegal mining, an activity that allows them to survive but threatens to destroy the land they inhabit. With the decline of gold, strategic minerals have risen as a promise for the future. However, this new mineral rush, which promises to be less polluting than gold mining, carries enormous environmental and social risks.

In the remote landscapes of the Orinoquía, the Minastyc project is emerging as a revolutionary venture for rare earth mining in Colombia. Behind its supposed economic and technological potential lies a complex web of legal conflicts, international tensions, and territorial disputes.

In the Colombian-Venezuelan borderlands — from the arid, rocky savanna areas near the Orinoco River to the dense, fertile stretches of the Amazon rainforest — lie some of the most coveted minerals on Earth. Their existence exposes a stark contradiction: the critical minerals essential for green energy and defense technologies are extracted through operations that destroy Indigenous communities, damage vital ecosystems, and fuel guerrilla violence, even as global powers compete for these same resources to build what they call a sustainable future. Here, in lands that Indigenous communities have inhabited for millennia, a new type of invasion is taking place.

On the Colombia-Venezuela border, the illegal mining of strategic minerals such as tantalum, niobium, and rare earth elements is fueling a transnational illicit economy involving guerrillas, armed organizations, and criminal networks. Colombia’s Orinoquía Naval Force has seized dozens of tons of these so-called “black sands.” However, the complexity of trafficking networks and the lack of a solid legal framework have made it impossible to curb the extraction and illicit flow of these materials. The absence of state control and the manipulation of mining titles allow the laundering of these minerals, while legal loopholes facilitate an illegal mining industry that could become one of the region’s main sources of conflict.

A complex network of actors has emerged around the critical minerals of the Amazon. Some operate along contested river corridors, trading with guerrilla groups and corrupt security forces. Others, under a façade of legality, move massive quantities of material through large port cities connected to international trade routes. Together, these operations endanger the environment and the sovereignty of entire nations.
