n the mountains of central China, a colossal antenna system stretches across the landscape.
Originally built for submarine communication, the massive system now drives China’s hunt for critical minerals. Stretching farther than New York City five times over, the 500-kilowatt transmitter is broadcasting signals deep into the Earth to uncover resources hidden kilometers underground.
As countries scramble to secure lithium, cobalt, and rare earths for green technologies, China has placed its bet on advanced electromagnetic exploration.
These systems, including the giant antenna, are helping geologists detect ore bodies and energy resources in places previously out of reach.
