Scientists discover largest 'invisible gold' reserve beneath Japan's seabed, but this one major problem may never let the underwater treasure be mined

Scientists have identified a vast reserve of hidden gold deep beneath the Pacific Ocean. This "invisible gold" is locked inside pyrite and requires advanced techniques to detect. The discovery occurred in an active underwater volcanic region off the coast of Japan. This finding renews interest in deep-sea mining while also raising environmental concerns. Commercial extraction remains uncertain due to technical and economic challenges.
