India’s Deep Ocean Mission: Unlocking Strategic Mineral Wealth in the Indian Ocean

The Ministry of Earth Sciences (MoES) recently announced a significant milestone under India’s Deep Ocean Mission (DOM) with the identification of potential hydrothermal vent sites in the Central Indian Ridge. These sites are known to be rich in polymetallic sulphides (PMS), which contain high concentrations of strategic minerals such as copper, gold, silver, zinc, and lead. Hydrothermal vents are essentially fissures on the seafloor where geothermally heated water is discharged. As this hot, mineral-rich fluid meets the cold seawater, minerals precipitate and form chimney-like structures. For India, the exploration of these vents in the Indian Ocean is not merely a scientific endeavor but a strategic necessity. As the global economy shifts toward a green energy transition, the demand for critical minerals required for electric vehicle batteries, solar panels, and wind turbines is skyrocketing. Securing domestic or controlled sources of these minerals is vital for India’s mineral security and to reduce reliance on volatile global supply chains.
