The Geological Survey of India (GSI), supported by the National Mineral Exploration Trust (NMET), has identified several high-potential zones in Northeast India containing rich deposits of critical and strategic minerals. These materials are vital for clean energy technologies, digital infrastructure, and defence manufacturing.
Through thematic studies, baseline surveys, and targeted exploration, GSI uncovered the presence of rare earth elements (REE), graphite, vanadium, lithium, cobalt, and other key minerals essential for batteries, semiconductors, and advanced alloys.
Meeting India’s Growing Demand for Strategic Resources
With India’s demand for critical minerals rapidly increasing, GSI emphasized the urgency of developing domestic sources. “India’s growing need for such resources underscores the importance of tapping geologically promising regions like the Northeast,” the agency noted.
Geological Formations Favour Exploration
The region’s unique geology—including ophiolite belts, ultramafic complexes, and graphite-rich schists—makes it exceptionally favourable for mineral exploration. These formations host several high-value minerals critical for energy storage and emerging technologies.
Arunachal Pradesh Emerges as Major Graphite Source
Among the Northeast states, Arunachal Pradesh has stood out as a key source of graphite. GSI has identified over 17.89 million tonnes of high-grade graphite in the state. With a carbon content ranging from 5% to 25% and fine- to medium-flake texture, the mineral is ideally suited for lithium-ion battery production. This positions Arunachal Pradesh as a vital player in India’s transition to clean energy and electric mobility. As reported by projectatoday.com, the government aims to unlock the mineral potential of Northeast India. This will help build resilient, self-reliant supply chains for strategic sectors and accelerate its clean energy ambitions.
