China has begun testing a 500-ton shaft boring machine, nicknamed “Gangtie Jiliang,” designed for deep-earth mineral exploration. The machine is intended to access potential resource deposits located over 1,000 meters below the surface. This represents a significant investment in accessing resources at previously unreachable depths. Details regarding the specific minerals targeted have not been released. The project signals China’s ambition to secure vital raw materials and reduce reliance on imports. The “Gangtie Jiliang” is being described by some as an “underground aircraft carrier” due to its size and capabilities. Successful deployment of this technology could revolutionize resource extraction methods.
