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.
The grayish-black sand and small stones sifted from river sediments and dug from pits across the Amazon hold little recognized value for local communities. Yet these materials are rapidly shipped abroad, where Chinese refineries process a wide variety of minerals and rare earth elements.
In Venezuela, much of the mineral output is first collected in centers operated by the Venezuelan Mining Corporation (CVM). Collection hubs for cassiterite and coltan in Los Pijiguaos and Morichalito, two nearby towns in the state of Bolívar, were established in 2023, after the Venezuelan government designated cassiterite, nickel, rhodium, titanium, and other rare-earth-related minerals as strategic resources for exploration, extraction, and commercialization.
