Deep-Sea Manganese Nodule Mining Robot Swarm AbyssMiner Completes First Commercial Test in Pacific Ocean: Seabed Mining Enters Operational Phase
AbyssMiner consists of 12 underwater robots collecting manganese nodules at 4,500-meter depth in the Clarion-Clipperton Fracture Zone and delivering them to a surface platform.
Deep-Sea Manganese Nodule Mining Robot Swarm AbyssMiner Completes First Commercial Test in Pacific Ocean
On September 17, 2030, Belgian deep-sea mining company Global Sea Mineral Resources (GSR) announced that its AbyssMiner robot swarm completed its first commercial-scale test mining in the Clarion-Clipperton Fracture Zone of the Pacific Ocean. During the 30-day trial, 12 underwater robots collected approximately 500 tons of manganese nodules at 4,500 meters depth.
Manganese nodules are spherical ore bodies rich in manganese, nickel, cobalt, and copper, scattered across the deep-sea sediment surface. These metals are critical raw materials for electric vehicle batteries and renewable energy equipment. The manganese nodule reserves in the Clarion-Clipperton Zone alone are estimated to exceed 30 billion tons.
The AbyssMiner system consists of three types of robots: 4 seabed collection robots (each weighing approximately 12 tons, equipped with vacuum suction devices), 4 relay pumping robots (transporting ore to the surface via pipelines), and 4 environmental monitoring robots (monitoring sediment disturbance and marine life impacts in real time).
GSR CEO Kris Van Nijen said: "AbyssMiner's design philosophy is to minimize impact on deep-sea ecosystems. The collection robots only vacuum approximately 5 centimeters of surface sediment, and the environmental monitoring robots detect any potential ecological impacts in real time and automatically pause operations."
Environmental organizations strongly oppose the initiative. The World Wildlife Fund (WWF) issued a statement saying deep-sea mining will cause irreversible damage to "Earth's least understood ecosystems" and called on all nations to suspend deep-sea mining permits.
The International Seabed Authority (ISA) is currently reviewing the regulatory framework for deep-sea mining, with formal commercial mining rules expected by June 2031.
